10,000-ton devices will be completed by the end of the year

The preliminary design of the fluidized bed methanol to propylene technology development project was recently approved by the Anhui Provincial Development and Reform Commission. The project was jointly developed by China National Chemical Engineering Corporation and Huaihua Group. It adopts the methanol-fluidized catalytic cracking technology developed by Tsinghua University to produce propylene, and Huaihua Group has established a 10,000-ton methanol catalytic cracking system to produce propylene industrial test devices. The device is scheduled to be commissioned by the end of this year.
It is understood that the methanol-fluidized catalytic pyrolysis technology for propylene developed by Tsinghua University has completed a small test and is of international advanced level. The fluidized bed methanol to propylene industrial test device project is to amplify this small-scale test result to the 10,000-ton scale and provide technical basis for the construction of a million-ton industrial device. The project mainly includes three parts: basic research, process amplification and industrial testing. The construction scale is to treat 30,000 tons of methanol annually, convert 10,000 tons of propylene, produce liquefied petroleum gas 800 tons, and invest a total investment of 170 million yuan. It is planned to be completed by the end of this year.
According to relevant experts, coal-to-olefin technology is the core technology for the development of new-type coal chemical industry and is an important development direction for the coal chemical industry in the future. The methanol reforming propylene pilot plant construction will develop methanol-produced propylene technology with independent intellectual property rights. Against the backdrop of rising world oil prices, the use of methanol as a new petrochemical feedstock has become a trend, and propylene is becoming an important platform compound and basic chemical raw material for petrochemicals.
It is predicted that the domestic demand for propylene will reach 19.05 million tons in 2010, but due to the shortage of petroleum resources in our country, it can only provide 10.8 million tons of propylene, which cannot meet the rapidly growing demand. The core of fluidized bed methanol to propylene technology is to use advanced gas generation technology to convert Anhui's abundant coal resources into methanol through the channels of coal to syngas, and then to produce low-carbon olefins from methanol. Less than half of the current production of propylene from petroleum.

Q: Generally speaking, there is a rule when choosing and installing intruder detectors, namely "passive indoors, active outdoors". Is this the universal matching principle?

A: The so-called passive and active are distinguished by the detection means of the detector. A passive infrared detector is a detector that uses a pyroelectric sensing element (PIR element) as the main detection means. The alarm is triggered by a temperature change in the detection range. Usually, a three-dimensional area is sensed, and the general ambient temperature in the room is constant. When there is an intruder, the detector will sense the difference between the human body temperature and the background temperature and alarm, while the outdoors due to the unstable ambient temperature, if you use an ordinary passive detector will cause a great false positive rate. The range of detection of passive infrared detectors is 120 degrees left and right, and 75 degrees up and down. Its detection range is wider than that of active infrared detectors. It is usually installed in a room or hall.

Active infrared detectors generally refer to photoelectric detectors. These detectors always consist of a photo-emission and a photo-detection end. The emission end emits an infrared beam that is invisible to the human eye, and the receiving end receives the infrared beam. Energy, it is always used in pairs: one launch, one receive. When someone traverses the surveillance zone, an invisible infrared beam is blocked and an alarm is triggered. The ambient temperature has little effect on it. As mentioned earlier, the detection range of a passive infrared detector is a three-dimensional space. Relatively speaking, the detection range of an active infrared detector can be described as a surface. It is mainly installed on windows, fences, and important entrances and exits. Its detection range is Only between the emitter and the receiver is an alarm triggered when someone or object passes through it. Due to the problems of detection efficiency, range, and غير مجاز مي باشدt in the room, active infrared detectors are rarely used.

Q: There are still dead angles when the active infrared detector is used for perimeter protection. How to solve this problem?

A: Due to the problem of the active infrared detector itself or the geographical environment of the detection area, there may be some small areas or small dead angles that cannot be completely sealed by the radiation detector. This brings certain hidden troubles to the security system and reduces the entire area. System reliability. Like the barrel effect, the entire security rating is determined by the weakest link in the system. Therefore, in order to solve these weak links, it is very necessary to select some outdoor curtain detectors to seal the corners.

Q: Since the PIR detector is a kind of weak signal detection device, some details of the installation may directly affect the detection effect of the detector. Then, what are the requirements on the angle and height when installing it? What are the places that are not suitable for installation?

A: To a large extent, the sensitivity, detection range, and installation height of the detector are directly related to each other. The optimal installation height of a typical passive infrared detector is 2.1 to 2.5 meters. If it is a pet-proof detector, then it is Mounting height requirements will be higher. If the installation is too high, the blind spot will be large. If it is too low, it may not be able to detect the far position. Therefore, the actual application also needs to be measured. For example, a curtain detector that belongs to the principle of passive infrared, if it needs to be installed on a window, the installation height at this time is 25CM away from the window sill. If it is too high, people can drill it from under the probe if the distance is too low. May be crossed from above.

The principle of passive infrared is to monitor the temperature difference. When the outside temperature is about 37 degrees, it basically fails, so do not install near the heat source. In addition, it is necessary to pay attention to avoid fluidity areas such as vents, air conditioners and radiators that can change the ambient temperature, and also to block the shielding of the middle shield (even if it is transparent, such as glass). Also, avoid moving objects such as fans, drying clothes, and curtains. Places where animal activity is frequent should also be avoided. If it is difficult to avoid the actual needs, then special attention should be paid to using a pet-proof detector.

Q: What are the rules for the installation of active infrared detectors?

A: The installation of the active infrared detector has some common sense installation specifications according to the specific conditions of the human body. For example, if a human invades, the invasion distance will be greater than 20cm regardless of whether it is horizontal or lateral. Therefore, the installation height should generally not be lower than the minimum. 20cm; In the case of an arc-shaped corner, the distance from the tangent to the arc shall not be greater than 20cm; when mounted on the fence, the distance between the edge of the fence and the center of the detector shall not be greater than 20cm. In addition, active infrared detectors require that the mounting bracket is stable and firm, and there should not be shaking. A slight deviation may cause the detector to fail. At the same time, there should not be sheltered branches and weeds in the detection range, so as to avoid causing too many false alarms. . There is also a need to consider the linearization of its detection, which is difficult to shape for some complicated and varied shapes.

Q: The detection distance of the active infrared detector determines its detection area. The nominal distance and the actual working distance of the general manufacturer do not match. How to determine the optimal installation distance?

A: Due to the defect of infrared technology, there is a certain error between the measured distance and the nominal distance when the active infrared detector is used for perimeter protection. This is also reasonable, but if the error is too large, it is the quality of the product itself. Manufacturers mark the working distance in the best weather conditions, but it is actually difficult to achieve such conditions, even if it does not last for a long time. Therefore, in a stable environment, the detector's detection distance can also reach the manufacturer's nominal distance, and sometimes the detection distance will be much higher than the nominal distance. However, under actual circumstances, the outdoor environment is an unstable environment. In particular, the energy loss of infrared light during rainy and foggy days is very large, and the nominal distance is often not reached at this time. Therefore, in practice, it is often installed in accordance with 50% to 70% of the nominal distance of the manufacturer. Therefore, the actual measurement is the most critical when selecting the anti-theft product.

Q: The commonly used detectors are wired. If it is installed indoors, there are many indoor circuits such as TV, stereo, and lighting. How can these lines not affect the normal operation of the detector? In addition, there is a certain distance between the detector and the line connected to the host. How can these lines be protected from being cut off?

A: Ordinary detectors generally use four-wire system, in which two lines are power (usually DC12V), and the other two lines are signals (usually NO/NC switch signals). In accordance with the engineering regulations, strong and weak currents should be routed separately, and the signal line of the detector is not easily affected by environmental disturbances. Therefore, TV, audio and lighting circuits will not be affected. Also, when installing, do not put together with strong electricity and electric appliances that can generate strong magnetic fields. Lines cannot go along with strong electric lines.

Whether it is indoor or outdoor, the wired alarm detector has a certain distance from the host circuit, so the protection of the detector circuit is also very important. At present, the detectors generally have a shear protection function. For the protection of the connection line, on the one hand, according to the grade of the project, it can be protected by means of steel pipes, PVC pipes, bridges or buried burial; on the other hand, the simple and easy way to prevent the line from being cut is the access line resistance. Each regular manufacturer's host has this feature. In addition, the qualified alarm host's zone detection circuit will respond to the cut of the line. Once the line is cut, the host will consider this detector as abnormal.

However, according to the current state of security development, it is not enough to have only the shear protection function. Because with the open management of the security industry, internal theft or technical crimes increase year by year, only the detectors with self-protection function can better protect Others.

Q: The active infrared working devices are mainly the transmitting and receiving lenses. What problems do they have during adjustment?

A: If these two lenses are misaligned, the direct result is to deviate from the center area, resulting in poor reception.

The adjustment of the active infrared detector should generally be based on the voltage output of the light receiving end. Through the fine adjustment of the deflection angle and vertical angle of the lens, the output voltage of the light receiving end can be observed. The higher the voltage, the more accurate the detector is, and the false alarm rate. The lower it is. Generally, the radiation detector will have a lowest output voltage index. The current shots are relatively simple to install and debug. As long as they are correctly installed in accordance with the installation method provided by the manufacturer, there is no problem under normal circumstances.

Q: Sensitivity is the most direct factor that affects the false alarm rate or missed rate of the detector. How to adjust the sensitivity so that the false alarm rate and false negative rate achieve the desired effect?

A: In the conventional detection technology, sensitivity is a contradiction between false positives and false negatives. To reduce false positives and lower sensitivity, it is bound to bring about the problem of missing reports; instead, it is increased to reduce false negatives. Sensitivity, in turn, raises the problem of false positives. It is difficult to accurately grasp this "degree" in practical applications.

The specific setting of sensitivity depends on the actual environment. In general, if the application environment is rather harsh, for example, there are often birds or blade floats blocking the beam, it should be set in a low-sensitivity range. The active infrared detector should choose the appropriate response time: if it is too short, it will cause unnecessary disturbances, such as flying over small birds, passing through small animals, etc.; too long will result in missed reports. The shortest shading time is usually determined at a speed of 10 meters per second. Sometimes due to seasonal changes, sensitivity is adjusted separately in winter and summer.

Q: Currently there are two-beam and four-beam infrared detectors.

A: The four-beam detector means more stability and lower false alarm rate, and the ability to adapt to the environment is stronger. It also means that the increase in غير مجاز مي باشدt is generally used in long-distance environments (nominal distance exceeds 100 meters). The more the beam is, the better the detection effect is. We need to look at where it is used. If the place is relatively small, we will use less beams, so we can reduce its false negative rate. If we use a larger area, we must use more. Beams of light, so that it can reduce its false positive rate.

The main purpose of multi-beam detectors is to prevent false alarms, because the principle is to cover the entire beam to alarm, from this point of view, as long as it is more than two beams, it is detected in the body of this range of objects, and the beam How much does not matter, only with the coverage area of ​​the beam. Of course, some products are currently considered to be infrared fences, which is due to the combination of multi-beam detectors.

Q: Shuangjian detector utilizes the dual technology of infrared and microwave, which reduces the false alarm rate and improves the accuracy. However, microwave technology itself can penetrate walls and other obstacles (and its shielding of metal). Does the stability and reliability of Shuangjian detectors suffer greatly?

A: The microwave detection range of the Shuangjian detector is generally wider than that of the passive infrared detector. The Shuangjian detectors of general manufacturers are equipped with microwave range adjustment knobs. During the debugging process, the detectors are observed by walking. The indicator light, through the microwave range adjustment knob and the angle of the mounting bracket, make the microwave range as close as possible to the passive infrared detection range. Microwave sensitivity must not be too large, because microwaves are only penetrating, and care should be taken during commissioning.

Will microwave technology affect the stability and reliability of the detector itself? It is understood that the answer is of course negative. Some manufacturers have also done a lot of useful work in this regard: such as increasing the frequency (the K-band frequency is 2-5 times that of other commonly used microwave frequencies), reducing leakage; increasing the degree of microwave molding, using a dedicated waveguide The shaped antenna makes the microwave and infrared highly complex, further reducing the microwave energy leaked outside the protected area.

All types of access gates are organically integrated with mechanical, electronic, microprocessor control, and various read-write technologies. They have become more and more popular in recent years, and are often seen in subways, stations, scenic spots, and halls. Various gates, such as the CD-T101 three-roll gate, CD-T301 wing gate, CD-T202 swing gate and so on. How to maintain and maintain the gate product? How to maintain the three-roll gate lock gate? Shenzhen Equator Science and Technology engineers guide everyone in this area.

First of all, we must know that the maintenance of the tunnel gate is of utmost importance. Like the automobile, it needs maintenance and maintenance. The maintenance and service of the gate affects the service life of the gate directly. Therefore, regular maintenance of the gate must be performed. To do, but also to do a good job, many users rarely maintain or even do not maintain, and other machines only think of manufacturers before they go to replace components. This is often due to small losses, usually there is no maintenance, a little bit of a problem, a long time will affect the use, so we must understand the importance of maintenance of the gate. Maintenance begins with the following aspects.

First, external cleaning and maintenance

The general gates are made of domestically produced 304 stainless steel, and it is recommended to clean the exterior once a week.

1, the surface is clean: Use a soft cloth to clean the surface of the dust, with a soft cloth and talcum powder to polish the outside of the chassis, conditions can be coated with anti-rust oil, just coated with anti-rust oil do not wipe by hand, etc. 3-5 About the hour, you can dry it by hand, otherwise it will destroy the effect of surface rust prevention.

2, the use of a long time, especially in outdoor use, there may be some rust spots, remove rust spots: use sandpaper and talcum powder along the long lines to wipe (protect thick grain direction), otherwise it will affect the appearance.

3, if it is the appearance of spraying or painting chassis, use a soft cloth to wipe off the dust on the outside, if exposed scratches, use the same color paint to make up, but be careful not to wing flap, swing gate of the radio eye part of the painted , otherwise the brake accident alarm, causing unnecessary trouble.

Second, movement maintenance

The movement is the heart of the machine and it must be maintained. It is recommended to maintain it once a month.

1. Cut off the power supply, open the cover of the brake, clean the dust on the surface, add the butter after cleaning the drive part first, and apply some butter to the gears and wheel slots of the wing lock and swing gate.

2. Check the fasteners and connecting rods for loosening and tighten them.

3. Check the wear of the wearing parts. The positioning arm of the tripod gate and the positioning plate have more than 3mm gaps and replace them in time. The normal clearance (1-1.5mm) is properly added to the solenoid valve core to make the solenoid valve Reducing resistance during left and right movements, and being lubricated, be careful not to add too much and be moderate.

4. Pay attention to the limit switch and the limit piece of the gate. Do not adjust it to prevent it from being too far or too close.

Third, the circuit power supply maintenance
1, cut off the power, clean the surface of dust. Be careful not to wash with water and prevent short circuits from occurring.

2, according to the previous use, to see if there is a problem in the circuit part, there is no problem, then check the circuit, power supply, wires, plug-ins are exposed or loose, to be bandaged, organize, tighten the plug, check for leakage, if the wire has Aging should be replaced.

3, refer to the gate manual, check whether the various parameters are normal, there are no aging electronic components. There are problems, we must contact the manufacturers, follow the steps, find the root cause of the problem, replace individual electronic components.

Fourth, the above maintenance must have someone special maintenance, especially the movement and maintenance of the circuit part, to go through professional training, full understanding of the strong and weak electricity, in order to post operations.

With the development and demand of the monitoring industry, intelligent automatic tracking generally uses panoramic cameras combined with high-speed domes or high-speed heads to increase work efficiency.

PTZ selection
PTZ can be simply understood as a base that can rotate freely in all directions (360° horizontal, 90° vertical). The use of the head to expand the camera's field of vision. In the television monitoring system, places that need to be monitored by the tour, such as halls, playgrounds, plazas, etc., often use PTZ.

PTZ is generally divided into ordinary type and ball type PTZ. Ordinary pan/tilt heads are bare pan/tilt heads. Camera guards are required to install cameras; ball heads are built-in pan/tilt heads, and global or semi-spherical shrouds are external, so ball heads are more beautiful than ordinary heads. Concealed and easy to install.

First, when choosing a PTZ, the following points must be noted:

(1) Identify indoor and outdoor installations. Outdoor PTZ is better than indoor PTZ waterproof, corrosion resistance, constant temperature and impact resistance, to adapt to outdoor complex climatic conditions, its weight and carrying capacity are also greater than indoor PTZ.

(2) According to special environmental requirements. Such as hotels, communities, government agencies, office buildings and other places, generally have higher requirements for concealment after installation, and therefore more use of ball-type PTZ. It should be noted that because the indoor hemispherical pan tilt needs to be embedded and installed, if the top of the wall cannot be hollowed out, it cannot be installed.

(3) If you add infrared light to the camera, you must use the ordinary head. Ball heads cannot mount infrared lights.

(4) Since the ball head does not have a mechanical wiper, if the wiper function must be used, only the ordinary head can be used with a wiper boot.

PTZ troubleshooting

A pan/tilt will not operate quickly or at all after it is used. It is a common fault of the PTZ. The appearance of this situation, apart from the factors of product quality, is generally caused by the following reasons:

(1) Only the pan/tilt that is mounted on the camera is allowed to use the lifting method. In this case, the hoisting method leads to an increase in the operational load of the pan-tilt. Therefore, soon after use, the pan-tilt mechanism will be damaged, and even the motor will be burned.

(2) The total weight of the camera and its protective cover exceeds the weight of the PTZ. Especially for PTZs that are used outdoors, the weight of the protective cover is often too large, and there is often the problem that the PTZ will not move (especially the vertical direction).

(3) The outdoor pan/tilt head is faulty or even damaged due to poor ambient temperature, too low, waterproof, and frost-proof measures.

2. When the distance is too far, the keyboard cannot be controlled by the decoder on the camera (including the lens) and the head.

This is mainly because when the distance is too far, the control signal is attenuated too much and the control signal received by the decoder is too weak. At this time, a relay box should be installed at a certain distance to amplify the shaping control signal.

3, the monitor image contrast is too small, the image is light.

This phenomenon is not the problem of controlling the host computer and the monitor itself, that is, the transmission distance is too long or the attenuation of the video transmission line is too large. In this case, the line amplification and compensation device should be added.

4, the image clarity is not high, the details are lost, serious color signal loss or color saturation is too small.

This is due to the fact that the loss of the high-frequency end of the image signal is too large, resulting in the basic loss of signals above 3 MHz. In this case, either the transmission distance is too long and there is no amplification compensation device in the middle; or the distribution capacitance of the video transmission cable is too large; or the equivalent capacitance is concentrated in the transmission link between the core wire and the shielded wire. Caused.

Hue distortion

This is a fault phenomenon that easily occurs in long-distance video baseband transmission. The main reason is caused by the large phase shift of the high frequency band caused by the transmission line. In this case, a phase compensator should be added.

Operation keyboard failure

This phenomenon can basically be determined as the "deadlock" of operating the keyboard when there is no problem in checking the connection. On the operating instructions of the keyboard, there are generally methods to solve the "crash", such as "reset the whole machine" and other methods, this method can be used to solve. If it cannot be solved, it may be that the keyboard itself is damaged.

The host does not clean the image

This failure phenomenon is manifested in the screen after the selection, the interference of other pictures superposed, or the interference of the line synchronization signals of other pictures. This is due to the poor quality of the host or matrix switch and the lack of isolation between images.
