Video Interference in Monitoring System and Its Solution

Closed-circuit television monitoring systems are used more and more in various fields. Under different environments, different installation conditions and different construction personnel, due to differences in line and electrical environment, or negligence in construction, it is easy to cause various types of interference. . These interferences will enter the closed-circuit television monitoring system through the transmission cable, resulting in the degradation of video image quality, system control failure, and unstable operation, directly affecting the quality of the entire system. Therefore, to understand the impact of video interference on closed-circuit television monitoring system, take corresponding measures to solve the interference problem for different situations, it is very beneficial to improve the quality of closed-circuit monitoring system engineering and ensure the stable operation of the system.

The main form of video interference is 1. A black bar or white bar appears on the monitor screen and scrolls up or down. This is the so-called 50Hz power frequency interference. Most of this interference is due to the potential difference between the grounding and the control center's improper grounding of the two devices, resulting in a loop entering the system; it may also be due to a drop in the power supply performance of the device itself.

2, the image has snow noise. This kind of interference is mainly caused by signal attenuation on the transmission line and coupling of high-frequency interference.

3, video images have ghosting, or the image is whitish, character jitter, or on the monitor screen to produce a number of equally spaced vertical bars interfere. This is due to impedance mismatch due to the fact that the characteristic impedance between the video transmission line or the equipment is not 75Ω.

4, twill interference, beating interference, power interference. The appearance of this kind of interference does not drown the normal image when it is light, but when the image distortion is serious, it cannot be watched. The cause of this kind of failure phenomenon is more and more complicated. For example, the quality of the video transmission line is not good, especially the shielding performance is poor, or because the power supply system power supply is caused by clutter, and there is a strong system nearby. Source of interference.

5, large area moire interference, also known as single-frequency interference. This phenomenon is mainly due to the short circuit caused by the video cable's core wire and shielded network, the failure caused by the open circuit, or due to the poor contact of the BNC connector.

The video interference encountered in the scene is nothing more than the above five conditions. Therefore, we encountered such phenomena in the scene. First of all, we must calmly analyze the types of interference that belong to which categories, identify the possible causes of interference, and finally come Exclude it. The following is a specific example to analyze the causes of video interference and how to eliminate it.

Figure 1 shows a schematic diagram of a typical video surveillance system. Such systems tend to produce images with twill interference or scrolling dark bars on the monitor. From the form of interference performance, we can determine that the main cause of interference is from line interference and power interference.

Vab=(Vo×75)÷[75×2+Rc+Rd]]+(Vi×75)÷[75×2+Rc+Rd]]

Among them, the first item is the effective video signal obtained by the load Voh=(Vo×75)÷[75×2+Rc+Rd]]. The second item is the effective interference signal obtained by the load Vih=(Vi×75)÷[75×2+Rc+Rd]];

When the cable is very short, the resistance of the inner and outer conductors can be ignored, Rc+Rd=0. At this time, the effective video signal Voh=(Vo×75)÷75×2+0)=Vo×75÷75×2=Vo/2=1 Vp-p. Since the disturbance induced electromotive force Vi is proportional to (Rc+Rd), Vi=0 and Vih=0 at this time.

It is worth noting that the interference signal Vi is determined by the longitudinal distribution parameters (impedance or resistance) of the cable, and is not a concentrated point source. The important point is that it is connected in series in the video signal transmission circuit, and the load is at the same time that the camera video signal is obtained. It must also acquire the interference signal.

The nature of the interference belongs to "additive interference" and it always exists regardless of the presence or absence of video signals. From the above formula, we can see that the most important method to eliminate interference is to sense the small electromotive force as much as possible. This should also be taken into account when handling.

Several major sources of interference A, the ground of the ground-interference front-end equipment and the ground of the control room equipment are different from the potential of the power-grid ground, that is, the potential difference between the two grounding points is different from the “ground” of the power grid. A power loop is formed between the camera and the matrix, and the video cable shield is grounded, so that the 50Hz power frequency interference enters the matrix, causing interference. For this kind of interference, because it is difficult to make the “ground” potential of each location exactly the same as the potential difference of “grid-ground”, a more effective method is to cut off the path of the formation loop and use a method of cutting off the ground loop, at the end of the camera. Do not ground and do insulation measures with the mounting bracket so that interference caused by grounding can be substantially eliminated. It is worth mentioning that, because the coaxial cable is too long, it will inevitably have joints in the middle. If the joints are not handled properly, the shield network will also cause such interference when it touches the metal trunking.

B. Power supply interference Caused by the power supply system's power supply is not "clean". The power source referred to here is not "clean" and refers to an interference signal superimposed on a normal power source. This type of interference signal on the power supply is mostly caused by equipment that uses thyristors in the power grid, especially high-current, high-voltage thyristor equipment. The pollution to the power grid is very serious, which leads to the power supply in the same power grid. Not "clean". For example, in this power grid, there are high-power thyristor frequency modulation speed control devices, thyristor rectifier devices, thyristor AC-DC converter devices, and so on, all of which will cause pollution to the power supply. For example, after an on-site system is installed, there is a twill interference phenomenon in the image, and no reason can be found. Later, it was discovered that since this system was installed in the summer, the room was already equipped with air conditioning during installation, and the air conditioner was in automatic operation. Once accidentally shutting down the air conditioning power supply, a miracle appeared and the image on the monitor was normal. Then plug in the air conditioning power supply, and the interference appeared again. The problem of being troubled for a long time was finally discovered. Later, UPS was installed to separate the system power supply from the air-conditioning power supply, eliminating interference. The solution to this situation is relatively simple, as long as the entire system is powered by a clean power supply or an online UPS.

C. The space radiation interference introduced by the transmission line This interference phenomenon is generated mostly because there is a strong, high-frequency space radiation source near the transmission system, the system front-end or the central control room. One of the solutions to this situation is to understand the surrounding environment when establishing the system and try to avoid or stay away from the radiation source; another way is to strengthen the shielding of the front-end and center equipment when the radiation source cannot be avoided. The transmission line is piped with steel and grounded.

D. Impedance mismatch The fault phenomenon caused by the mismatch of the characteristic impedance of the transmission line. This is due to impedance mismatch due to the fact that the characteristic impedance of the video transmission line is not 75Ω or the characteristic impedance of the device itself is not 75Ω. For such interference, the impedance of each device in the system should be matched as much as possible.

As more and more matrix cascading systems are now in place, cascaded matrices are generally used where control points need to be managed separately and managed in the main control room. In the cascade system, if the distance is close, the video line may be directly connected between the matrices. In this way, the interference is very easy to occur. Especially since the two matrices are not together, the ground potentials of the two grounds are inconsistent. The most prominent interference of this system is ground interference. After this kind of disturbance appears, it is very difficult to handle. For the suppression of such interference, there are methods that have been solved in the project.

For the interference generated by this type of system, there are the following suppression methods:

1. Where possible, cascading video signals and control signals use optical transceivers as much as possible to transmit video, so optical isolation can better solve this interference problem. However, because the price of optical transceivers is relatively high, and not every place has the conditions for laying optical cables, this method is not applicable everywhere.

2. Install video anti-jamming isolator between cascaded video signals. Video anti-jamming isolator is a modern high-tech patented product. When audio-visual equipment is connected to produce various cross-talk interference, the product is connected in series on the video line, which can effectively isolate various interference signals and restore the original image and improve the quality of signal transmission. . The video anti-jamming isolator is a low-distortion, high-performance video isolator consisting of a wideband, high-performance band-pass filter and a high-performance video operational amplifier. Its use enables the remote and near-end video cables to be electrically powered. Completely in isolation, this fundamentally completely avoids the interference caused by the ground potential difference, and at the same time can effectively suppress the system damage caused by lightning shock. Due to the isolation of the electrical signal, the video anti-jamming isolator can also effectively avoid the interference of the interference signal to the video signal due to the environment high frequency, pulse and the like.

Anti-jamming isolator features:

●Simple installation, just connect the receiving end of the video cable in series;

● This product does not require an external power supply;

● Adopts wideband, high-performance bandpass filters;

● Optically isolated video signals;

● Effectively suppress the black-print rolling interference caused by the difference in ground potential;

● Effectively suppress high frequency moire caused by the phase of the power supply;

●It can also suppress high-frequency pulse interference caused by insufficient cable insulation;

● For long-distance transmission of video signals, with phase adjustment, signal amplification;

● Effectively isolate the impact of lightning on the system equipment.

3. Use a modem to increase the signal frequency and transmit it.

E. The relationship between the interference wave propagation distance and frequency According to the relationship curve between the interference wave propagation distance and frequency, it can be seen that the lower the frequency is, the longer the propagation distance is. This also means that the lower the frequency, the greater the chance of interference and the greater the intensity. Therefore, using the signal to increase the frequency after transmission, in the center and then the signal modulation and filtering can also greatly reduce the interference.

Because each monitoring system has its own different characteristics, it will produce such interference, so correctly analyze the causes of interference, and take effective measures to suppress interference, to ensure the quality of the project and equipment to run well, the monitoring system looks Especially important.

Slow demand for Chinese tool market

Slow demand for Chinese tool market The demand for the tool market in the world is constantly increasing. Among them, European and North American countries have maintained stable growth, especially in Eastern European countries. The Asian market has picked up slightly. The market has great potential. The Latin American market has grown significantly, especially Mexico.

In terms of technology updates, carbide cutting tools have gradually replaced high-speed steel tools, especially circular tools. The application of coated cutters is becoming more and more common. In Europe, the market for new cutting tools for high-speed machining continues to increase. The dynamics of the manufacturers. Judging from the cooperation mode of tool manufacturers, many large companies will emerge in the high-tech market.

At present, the domestic market has a large demand for medium-to-high-grade molds. During the 12th Five-Year Plan period, the general trend of the mold market has been steadily upwards. However, domestic molds must meet the needs of users in terms of quality and delivery time. Moreover, the home appliances, automobiles, and plastic products industries have the greatest demand for molds. In the international market, labor غير مجاز مي باشدts in industrialized countries have increased in recent years and they are being transferred to developing countries, especially Southeast Asian countries. Its domestic production of high-precision molds, labor-intensive labor-intensive molds rely on imports to solve.

Therefore, the medium and low-end mold international market has great potential. As long as the quality of domestic molds can be improved, the delivery date can be guaranteed, and the outlook for mold exports is very optimistic. In addition, the demand for mold standard parts in the international market is also large. At present, China has only a small amount of exports.

In the new wave of world economic integration, the global manufacturing industry has accelerated its shift to mainland China, and China will gradually develop into a world-class manufacturing base. The obvious advantages of Guangdong, especially the Pearl River Delta region, will develop into a global mold production center within 10 years. At the same time, due to the fact that China has imported molds for nearly US billion per year in recent years, among which the precision, large-scale, complex, and long-life molds account for the majority, starting from the perspective of reducing imports, the proportion of such high-grade molds and hardware tools in the market will gradually increase. Increase. In the future, China's mold and CNC tool industry will also be among the best in the world.

In the past year, the slow growth in demand for the Chinese tool market was mainly due to the increase in tool life. Then there was a request from the user for the entire manufacturing process that replaced many machine tools and tools. And the use of multi-purpose tools has increased, replacing many simple tools that used to be single-function.

In the future, the user will place greater emphasis on the research and development of the tool in the production plant, not only in the field of materials and surface coating technology, but also in the production of cutting tools and their production processes. The focus on production practices will help tool manufacturers increase their Familiar with the market competitiveness in the field.

From the perspective of the development trend of the machinery manufacturing industry, the main components of high-efficiency CNC advanced cutting tool CNC machine tools in our factories in the future. The proportion of machine tools will increase year by year, and the demand for efficient and advanced tools will also increase. The country is a big country in the production and export of hardware tools. Most of the world's electric tools are manufactured and exported from China. Although the tool industry in China is large in size, it is weak in technological innovation, the market structure is too single, and the brand influence is strong. Weak and other factors, many tool manufacturers often lack core competitiveness, low-end product technology, it is difficult to become bigger and stronger. The advanced cutting tool is an essential part of the CNC machine tool, but there is a big gap between the tools produced by domestic tool makers and foreign advanced tools.

China's machinery manufacturing industry uses a large number of standardized cutting tools, while developed countries use a large number of highly efficient cutting tools. This results in a much lower processing efficiency in China than in developed countries. Knife makers in the country are still producing a large number of aggressive standardized cutting tools. Even some small-sized tool manufacturers still produce a large number of low-grade cutting tools. These low-end cutting tools are put into the market and not only have no market, but will reduce the development level of the entire industry. Of course, there are also quite advanced cutting tools in manufacturing in Tianjin, Shanghai and other places. There is still a difference in prices, but the trend is that the demand for advanced cutting tools is increasing year by year. According to statistics, the country consumes 40% of the world's tool data, but its sales revenue only accounts for 12%-15% of the world's tool industry. The gross profit rate of the tool companies in developed countries is all around 40%, while the profit of China's tool factory is very low, and some of the tool factories are still losing money.

Judging from the technological development trend of the machinery manufacturing industry, the proportion of high-efficiency CNC machine tools in China's factories will increase year by year, and the demand for efficient and advanced tools will increase rapidly, while the demand for aggressively-regulated tools will decrease year by year. In addition, due to the increase in labor غير مجاز مي باشدts in China, the price advantage of the middle and low-grade standard cutting tools will gradually be lost, and the import volume will be reduced accordingly. Judging from the technological development trend of the machinery manufacturing industry, the proportion of high-efficiency CNC machine tools in China's factories will increase year by year, and the demand for efficient and advanced tools will increase rapidly, while the demand for aggressively-regulated tools will decrease year by year. For the current situation of increasing demand for advanced tools for numerical control machine tools, China's tool industry must change its philosophy, vigorously develop the production of high-efficiency cutting tools, pay attention to sales, but also pay more attention to after-sales service, and strive to occupy more market share.

ZeroLatency is about to push 8 people to synchronize large space VR experience

Recently, the brand Zero Latency, a well-known VR offline experience brand, announced the upcoming 8-person VR experience. This broke the record that the company had previously supported up to six people for synchronization. The first VR experience hall with 8-person games is being tested in Melbourne, Australia, with a site area of ​​nearly 400 square meters.

The company stated that there will be two existing venues and three additional new venues with a VR experience of 8 people.

“Our goal has always been to create epic social VR games that connect different players and create beautiful memories for them,” said Tim Ruse, CEO of Zero Latency.

“In 2015, we created a large-scale VR experience at the warehouse scope level and simultaneously supported six people to synchronize games. Through our exclusive motion capture technology, we have now achieved support for more players at the same time.”

At present, the company has 8 VR offline experience halls in the world, ranging from 200 square meters to 400 square meters. There are no walls and obstacles in the stadium, so players can walk around and explore safely.

In VR, the player will have a virtual image that reflects his actions in real time, which is a very realistic reflection of the strategy, call for help, and battle scenarios.

Zero Latency CTO Scott Vandonkelaar said that the company’s 12 technicians spent six months upgrading the system to support eight players.

“We are already a leader in the industry. The biggest difficulty at present is how to cope with the increased load of wireless data transmission after the increase in number. We must deal with huge real-time game data and network transmission data at the same time.”

Zero Latency currently has VR outlets in Melbourne, Australia, Tokyo, Japan, Madrid, Spain, and several locations in the United States. Boris Bielert, executive director of Zero Latency, said that by the end of 2017, the company will open operations in five other locations in South East Asia; Zero Latency has seen tremendous growth in the past fiscal year with a turnover of .5 million.

Seven major subsystems of integrated wiring system

The integrated wiring system can be divided into seven subsystems, which are the work area subsystem, the wiring (horizontal) subsystem, the trunk (vertical) subsystem, the equipment subsystem, the management subsystem, the building cluster subsystem, and the optical cable transmission. system.


The integrated wiring system is a set of wiring systems specially designed to meet the development needs. For a modern building, like the nerves in the body, it uses a series of high-quality standard materials to synthesize voice, data, images and some control signal systems with a unified transmission medium in a modular combination. After a unified planning and design, integrated in a standard wiring system, the three major subsystems of modern architecture are organically connected to provide a physical medium for the system integration of modern architecture. It can be said that the success of the structured cabling system is directly related to the success of the modern building, and it is crucial to choose a high quality integrated cabling system.

The integrated wiring system is an open structure that can support telephones and various computer data systems, and can also support the needs of systems such as conference televisions and surveillance televisions. The integrated wiring system can be divided into seven subsystems, the work area subsystem, the wiring (horizontal) subsystem, the trunk (vertical) subsystem, the inter-equipment subsystem, the management subsystem, the building cluster subsystem, and the optical cable transmission system.

1. Working area subsystem An independent area that needs to set up the terminal, namely a working area. The working area subsystem should be composed of the information outlet of the wiring (horizontal) wiring system, extending to the connecting cable and adapter at the workstation terminal equipment.

2. Wiring (horizontal) Subsystem The Wiring Subsystem consists of an information outlet for the work area, wiring cables from each wiring device to the information outlet, floor wiring equipment, and jumpers.

3. The trunk (vertical) subsystem trunk subsystem shall consist of wiring equipment and jumpers between equipment and connecting cables between the equipment and the floor wiring.

4. Inter-equipment subsystems The equipment room is where the incoming equipment, network management, and management personnel are placed at appropriate locations in each building. The inter-equipment subsystem consists of various wiring devices, telephones, data, computers, and other host devices and their security wiring devices.

5. Management Subsystem The management subsystem is located in the room of each level of wiring equipment. The management subsystem should be composed of the distribution equipment, input/output equipment, etc., and the management subsystem can also be applied to the equipment subsystem.

6. Building Complex Subsystem The Building Complex consists of telephones, data, and television systems for two or more buildings. A building complex wiring system includes cables and wiring equipment that connects the buildings. ), composed of building complex subsystems.

7. Optical cable transmission system When the integrated wiring system needs to lay a longer distance between buildings, or in the building information system requires the formation of high-speed networks, or with other external networks, especially with the power cable network When electromagnetic interference is required, optical cables should be used as transmission media. The optical cable transmission system should be able to meet the comprehensive transmission requirements of the building and building environment for telephones, data, computers, televisions, etc. When used in computer local area networks, multimode optical cables should be used; as a part of long-distance telecommunications networks, single mode should be used. Optical cable.

The above is the composition diagram of the seven subsystems in the integrated wiring system. It is not easy to remember the integrated wiring system in the graphic understanding, and hope to help everyone.

CMB’s freeze of LeTV Assets “has a bad head”? Other banks may follow suit

Text | Fang Yuanying Yang Lin

It is undeniable that Jia Yueting is now in crisis.

A tough move by China Merchants Bank to collect debts from LeTV is pushing him to the corner.

Assets were sealed - this is the worst of many situations. The situation of LeTV is quite similar to that previously understood: In the past, banks may have a grace period after the loan expired, waiting for the company's cash flow to come back for repayment. “But Levision lacks profit points, the longer it takes, the more it loses. Now, it is to see who understands first and who will go to court to sue it,” said one insider.

The person also believes that if LeEco has a timeline that may close in the face of a lot of run, "that is to see which bank reacted to first sue him and closed his account." Prior to this incident, LeTV Accounts that have been opened in multiple banks have been rejected.

The worrying scene has already taken place. On the afternoon of July 3, according to media reports from Tencent and Handan, China Merchants Bank Co., Ltd. Shanghai Chuanbei Sub-branch applied for property preservation from the Shanghai Higher People's Court on June 26, 2017. The application was ruled by the court to comply with the law.

According to the exclusive understanding of 36 Miles, Lefeng Mobile Hong Kong Co., Ltd., as the main borrower, had a loan to China Merchants Bank Shanghai Chuanbei Sub-branch. The loan amount was nearly HK0 million, and the loan was due in mid-July this year.

China Merchants Bank’s move is a prelude to the prosecution of LeTV. “China Merchants Bank Shanghai Branch applied to the court for asset preservation this time, which is a legal measure adopted by LeTV after its unsuccessful interest in Leward Mobile Loan, and after China Merchants Bank’s Shanghai branch has repeatedly received no results.” Merchants Bank responded in a speech tonight.

The contents of the court's specific rulings were: Freeze Levent Mobile Hong Kong Co., Ltd., LeSports Mobile Intelligence Information Technology (Beijing) Co., Ltd., LeTV Holdings (Beijing) Co., Ltd., Jia Yueting, and Gan Wei's bank deposits totaling RMB 1.237 billion, or Seize other equivalent assets.

In this regard, a legal person told 36, according to the contents of the court's ruling, this is the property preservation of China Merchants Bank before the lawsuit, and the bank should also prosecute Jia Yueting and his three companies.

The reason why Jia Yueting and his wife are two natural persons is also involved. There are two main possibilities. One is Jia Yueting’s guarantee with his own personal property and the loan from China Merchants Bank; the other is Jia Yueting as the legal person of LeTV Holding. Joint liability guarantees.

If this single loan itself is concerned, it is not too much of a problem for LeTV. LeTV responded to this issue by saying 36, “We have mortgaged the assets of this loan, and it is sufficient to cover the debt.” China Merchants Bank’s public response also has room to turn around. “The follow-up does not rule out solving problems with LeTV through friendly negotiation.”

However, the fatal consequence of CMB’s move was that it “brought a bad head” to other banks and creditors.

Previously, 36-year-old had reported in the in-depth manuscript “Sun Hongbin entered LeTV, Jia Yueting's harder one hundred days” that LeTV had been experiencing “runs” in recent months. There is no shortage of banks that are worried about recovering funds. There are about one to twenty banks that come to the door, and some banks that are not yet due are still watching.

LeTV still has a lot to wait for. At the shareholders’ meeting on June 28, Jia Yueting acknowledged for the first time that since LeTV saw the outbreak of the capital chain crisis, they had taken many measures and also made some mistakes. As a result, the system and funds of LeTV’s non-listed companies have even More nervous. Received 9.7 billion in funds, but actually paid more than 15 billion yuan. After returning the financial institutions' arrears, there is still no follow-up financial support from financial institutions.

The dilemma that there is no follow-up financial support must be traced back to April this year. For the first time, LeTV's financial report issued non-standard audit opinions from the audited companies since listing, and there are huge differences between some of the performance data and the performance earnings bulletins released earlier. Auditing agencies’ attitudes are alarming for financial professionals. "Before the financial report did not come out, LeTV may still be able to make loans. Now all banks have gone to LeTV to receive loans. No trust or fund has dared to lend it." An informed source told 36.

Now, China Merchants Bank’s tough debt-paying measures have risen by one level compared to the past. According to 36 reports earlier this year, as of May this year, five or six banks have already come to LeTV for debt collection. The approach is to directly “block the door”.

China Merchants Bank apparently believes it is a good idea to adopt such a tough approach today. "After applying for asset preservation, the business risk of China Merchants Bank Shanghai Branch and LeTV is currently under control," said China Merchants Bank.

"Either way, once the court decides that the bank is successful, if LeEco cannot repay the loan by then, the frozen assets will enter the auction process." A legal industry source told the 36-year-old reporter.

In the future, will there be other banks that will study China Merchants Bank to take lawsuits and freeze LeTV accounts to recover debts? It is very likely.

In the banks that have tasted back, China Merchants Bank is probably the first case.

Pipeline instrument operation method explanation

Pipeline instrument manufacturers

The underground pipeline detector is one of the essential instruments of the water company, gas company, railway communication, industrial and mining, infrastructure, transformation, maintenance, and census underground pipelines. It can quickly and accurately detect the underground without damaging the ground cover. The location, trend, depth of pipelines, metal pipelines, cables, etc., and the location and size of damaged points in the corrosion protection layer of steel pipelines.

The vast majority of underground pipelines are metallic materials that can transmit electromagnetic waves. Based on this principle, Baoying Huachen Power Equipment Factory designed and developed an instrument that can intelligently detect the position of pipelines by detecting electromagnetic waves emitted from pipelines. detector. The underground pipeline detector has a wide range of users in fields such as electric power, telecommunications, water supply, thermal power, gas, petroleum, chemical industry, and urban public utilities with its superior performance, flexible and convenient detection methods.

Here we take the intelligent pipeline detector of Yangzhou Zhili Company as an example to introduce the operation method of the underground pipeline detector in detail:

1. There are three ways to connect transmitter transmitters: direct connection, inductive coupling, and induction. We focus on direct links:

direct connection:

(1) Insert the cable to turn off the transmitter and insert the straight cable into the transmitter output socket.

(2) Connecting with the conductor Connect the red wire of the connecting wire to the target-uncharged metal part.

(3) Choose the grounding method. Connect the black lead of the connecting wire as far as possible from the pipeline and make a right angle with the pipeline. Look for metal ready grounds (such as street signs). Be careful not to go near any underground conductors nearby. If there is no existing grounding point, grounding solder can be used. Ground the solder as much as possible, then connect the black lead. To improve the conductivity. Can be poured under the board (4) Select frequency audio: for good conductors and long distance positioning.

IF: Intermediate frequency radio frequency for audio RF: General positioning of pipelines with dense piping or non-metallic joints.

(5) Select output power Select high and low gears according to specific conditions.

(6) Check loop resistance The transmitter automatically checks the loop resistance and displays the measured resistance in the LCD. The higher the resistance, the weaker the signal of the conductor. The resistance cannot be reliably positioned when the resistance exceeds 30KΩ. It is possible to change the position, preferably on moist land or on the ground, thus reducing the resistance of the ground. If necessary, move it several times to find the point with the least resistance. Note: Be sure to turn off the ground before pulling out the ground. After a good boot.

Warning: Never connect directly with live cables. Be sure to disconnect the cable when connecting directly to the cable.

2. Receiver Path Pursuit (1) The receiver is turned on.

(2) Check the battery level. When the battery level is low, replace the battery.

(3) Set the frequency and press the frequency key to set the receiver to the desired frequency. If active positioning mode is used, the frequency of the receiver should match the transmitter. The frequency of selection depends on the test conditions. Audio and RF have their own strengths. The audio wavelength is larger and the transmission distance is longer, so audio is generally used first. If the signal abruptly vanishes, disappears, or turns or turns accidentally, then the RF verification results must be used again.

Sensitivity setting The "gain plus minus" key is used to increase or decrease the gain and increase or decrease the sensitivity. If the reading of the number is too low, adjust the Gain Plus key so that the bar graph reading is between 40-50 of the entire range. Similarly, if the digital reading is too high, adjust the Gain minus key so that the bar graph reads between 40-50 of the entire range.

Select the track mode and press the mode key to select the crest or trough pursuit mode.

The wave peak method keeps the detector of the underground pipeline detector substantially perpendicular to the ground and moves the receiver above the pipeline. When the receiver is directly above the pipeline path, the maximum value can be obtained by moving the receiver. See below. When you shake the receiver gradually away from the pipeline path, the bar graph and readings (acoustic response frequency) will decrease; when you shake the receiver directly above the pipeline path, the maximum segment of the intensity value will show the path of the pipeline. It is consistent with the receiver's plane. Then start tracking at the transmitter at the right speed and move the receiver left and right. Watch the table for indications of peak readings.

The trough method is required to make the plane of the receiver perpendicular to the direction of the pipeline when tracking the survey, and vice versa. When the plane and the direction of the pipeline are parallel, the measured intensity is the minimum. This feature is often used to determine the direction of the pipeline.

Move the receiver above the pipeline. When the receiver is directly above the pipeline path, the receiver can get the minimum value and the sound response is also very small. When you shake the receiver off the minimum, the meter's reading will rise to a peak: and the voice response will be in its highest segment. As the receiver shakes along the peak area, the meter's reading will start to decay. Then start tracking from the transmitter at a moderate rate while shaking the receiver side to side. Look at signal strength and reading indications.

3. Scan and search (sensing search)

Inductive search is the most reliable technique for detecting unknown pipelines. This search method requires a transmitter and receiver and two operators. This search method is called "two-person search." Before starting the search, determine the areas to search for and the possible directions through which the pipeline passes. And set the on transmitter in induction mode. The first person operates the transmitter and the second person operates the receiver. When the transmitter passes the pipeline, a signal is applied to the pipeline, and then the receiver can detect the signal 20 meters upstream or downstream from the transmitter. The direction of the transmitter is consistent with the estimated direction of the pipeline. The second person is holding the receiver at the beginning of the area to be searched and the direction of the antenna of the receiver remains perpendicular to the direction of the possible underground pipeline. The receiver is tuned to the highest sensitivity that will not receive transmitter signals directly from the air. When the direction of the transmitter and receiver is correct, the two operators move forward in parallel. The operator carrying the receiver moves the receiver back and forth while moving forward. The transmitter applies the signal to the pipeline directly below and the receiver detects the signal. Mark the ground at the receiver's detected peak position. Repeat the search in other directions where there may be a pipeline crossing.

4. Induction skills:

Keeping the Distance Between the Transmitter and the Transmitter In the inductive mode, the transmitter sends a signal to the air in addition to the target pipeline, which may interfere with the probing work near the transmitter. To check that the receiver is detecting a signal in the pipeline, rather than a signal directly from the transmitter, move the transmitter a meter or two, and if the pipeline also moves with it, this indicates that the receiver is too close to the transmitter. Another way to check whether the receiver receives the transmitter signal is to point the receiver at the transmitter. If the response size of the receiver does not change or increase, it indicates that the receiver received the transmitter signal directly from the air. In this case, the transmitter output power is reduced and the receiver sensitivity is reduced. The receiver may also have to leave the transmitter 25 to 30 meters. Do not place the transmitter on the well cover as this will prevent the signal from reaching the pipeline.
