Today, security monitoring has become one of the most important components of our security work. From the high-definition front-end camera, to the more convenient network transmission monitoring, and to the more powerful storage and high-definition video display on the back-end, the increase in this investment alone has explained to us the importance of video surveillance in the entire security work. ***. However, high investment may not necessarily achieve ideal returns. For many users, although the front-end monitoring equipment is sufficiently advanced, there are more users who use their back-end display to make their equipment "fall In the last step "before.

In fact, the monitoring monitor's interference elimination is not a problem. There are many times when a small, simple process can make our monitor “full of blood”. Today, the author will teach you how to remove the most common interferences. Ways to make the monitor no longer suffer from interference.

The most common interference: wood grain interference

In our application, wood grain interference is probably one of our most common disturbances. Not only monitors, but also TV lines transmitted on some old-fashioned non-wired video signals have been harassed by these lines. In light conditions, it may affect our visual fatigue, but it may even affect our normal viewing. Therefore, this is often regarded as our number one interference situation.

In fact, there are many reasons for this week's disturbances, and the most common one is caused by flaws in video transmission cables. In the construction of the monitoring system, the cables are often the most easily overlooked part of the network, so it is also easy to cause uneven quality of the cables. When the quality of the copper wire inside the cable is not high, or the outer screen is too sparse, it will have a very significant impact on the video display of the terminal. This is mainly due to the different cable quality leads to the resistance of the entire line is too large, and ultimately affect the quality of the signal transmission. For the solution of this line interference, the use of cable replacement is probably the only way.

Maximum area interference: moire interference

However, due to similar causes of interference for many reasons, the determination of the failure is undoubtedly the most important task, and it is recommended that it be done by an experienced person to avoid unnecessary error overhead.

In fact, in addition to the line problem, wood grain interference is sometimes caused by strong current harassment near the transmission line. This is mainly due to the presence of superimposed interference of normal power supply during the transmission of the line, or caused by the thyristor equipment in its own power grid, and these will also have a great impact on the transmission of the line. Of course, the handling of this interference is obviously much easier than the above method, as long as we can use the clean power supply or online power supply in the entire system, we can pass this small line pattern out.

In addition, the pasغير مجاز مي باشدe of strong currents around the perimeter will also affect our circuits. For this problem, we will use enhanced shielding for the front-end equipment, or ground the video cable.

In addition to our most common wood-grained disturbances, there is another type of disturbance that occasionally affects our viewing vision, which is web-based interference. In our common interference phenomenon, the area of ​​influence of this interference can be regarded as one of the largest. However, although its coverage is relatively large, it does not seem to be "dominant" when it is solved.

For the emergence of such failures, it is generally due to the short circuit or the open circuit of the transmission cable core of the video cable and the surrounding protection network. Therefore, such problems often occur mostly in BNC connectors or other types of connector parts. When we solve a similar problem, we can easily troubleshoot this type of interference by checking the corresponding connectors one by one and replacing the problem devices.

The most neat disturbance: vertical bar interference

Although this type of interference may not be very common, its characteristics are quite obvious. The main reason for the formation of such interference is that the quality of the cable is not in line with the standard, which ultimately results in abnormal data properties in the transmission process.

Therefore, in solving this kind of interference situation, most of us will use "start series resistor" or "terminal parallel resistor" approach to solve. Of course, the best way to prevent this interference is when we purchase the line, we must carry out the necessary product testing, early detection of the problem, so as to avoid facing a rework mess after the project is over.

The above three types of interference basically cover one of the most common interference phenomena in video surveillance. From the above analysis, it is not difficult to find that the reason for the existence of an equivalent part is due to the equipment or construction defects. Therefore, this also reminds us that in reality, interference is not a big problem. It is only when we construct or purchase accessories that we need to conduct more and more rigorous testing on the equipment. We must grasp the quality of the product at the source so that we can't use it in the final application. Leave troubles that can be avoided.

With the extensive installation of explosion-proof electrical equipment for hazardous materials explosion hazardous locations, the relevant knowledge should also follow up. Explosion-proof electrical appliances are mainly explosion-proof electric air-conditioning, explosion-proof switch electrical appliances, explosion-proof distribution boxes, explosion-proof instruments, explosion-proof complete sets of equipment and electrical accessories.

With the extensive installation of explosion-proof electrical equipment for hazardous materials explosion hazardous locations, the relevant knowledge should also follow up. Explosion-proof electrical appliances are mainly explosion-proof electric air-conditioning, explosion-proof switch electrical appliances, explosion-proof distribution boxes, explosion-proof instruments, explosion-proof complete sets of equipment and electrical accessories. During the use of these devices, due to mechanical wear or material aging, or affected by the use of the environment, or due to equipment inspection, maintenance, repair work errors and other reasons, so that the explosion-proof electrical equipment explosion performance is reduced or even lost, it will cause the formation of ignition sources Explosion or fire accident. Therefore, in the inspection, maintenance and repair work of explosion-proof electrical equipment, how to evaluate the safety and usability of the old explosion-proof electrical equipment is an urgent problem to be solved.
Operational and environmental conditions affect the safety of in-use explosion-proof electrical equipment

Parts 1, 2, 3, 4, 5, 6, 7, 8 and 9 of CB3836 “Electrical Equipment for Explosive Gas Environments”, for the structure, design, manufacture and inspection of explosion-proof electrical equipment of different explosion-proof types Specific regulations. The explosion-proof products manufactured by the manufacturer must meet the requirements of the standard, and must be subjected to explosion-proof inspections by a nationally authorized explosion-proof inspection agency, and production and sales must be allowed after obtaining the explosion-proof certification. The bulk explosion-proof products manufactured by the manufacturer must pass the specified factory inspection and be allowed to leave the factory after passing the inspection. Therefore, in general, the explosion-proof safety performance of new explosion-proof electrical products fully meets the requirements of the standards. However, explosion-proof air conditioning products are affected by working conditions and environmental conditions during use, and are subject to varying degrees of wear and tear. Some damages have an adverse effect on the performance of explosion-proof air-conditioning products; some damage will also reduce the explosion-proof electrical products. Explosion-proof safety. For example, the switch electrical component contacts installed in an explosion-proof flameproof distribution box will have poor contact due to mechanical wear, electrical corrosion, or chemical corrosion, which will affect the use performance of the distribution box; The joint surface is corroded for a long time and rust occurs, so that the flameproof performance is reduced or even lost.

The adverse effects of operating conditions and environmental conditions on explosion-proof electrical equipment are:

Poor operating conditions

Explosion-proof electrical equipment is subjected to strong vibration or impact during operation, which can affect the mechanical structure and strength of small electrical equipment, and can also cause loose electrical connections. Frequent start-up, reverse braking, and overload of the motor will affect the winding temperature of the motor. And the surface temperature affects the safety and service life of the equipment. Increased safety electrical equipment is susceptible to adverse operating conditions.

Wet environment

Explosion-proof electrical equipment is operated or stored in a humid environment for a long period of time, which will affect the insulation of electrical equipment, making it easy for electrical equipment to reduce the insulation resistance, cause electrical breakdown or leakage, and destroy the explosion-proof safety of increased safety type and non-spark type equipment. ***uality can also adversely affect the operational safety of flameproof or other explosion-proof electrical installations. In addition, moisture in the environment will cause flameproof welding of the flameproof equipment and cause corrosion, which will have an adverse effect on the safety of explosion protection.

Corrosion environment

The corrosive environment has a great influence on the explosion-proof electrical equipment. Severe corrosion will cause corrosion of the electrical equipment housing and the fasteners and flameproof joints, destroy the flameproof security of the flameproof housing, and also make other explosion-proof electrical The degree of protection of the device housing is reduced. In addition, corrosive environments can also have an adverse effect on the insulation of electrical equipment, and can also erode exposed conductors, making them poorly contacted and creating sparks.

Ambient temperature

Ambient temperature in excess of 40°C will affect the winding temperature and surface temperature of electrical equipment, because normally the allowable ambient temperature range of explosion-proof electrical equipment is -20°C to +40°C, and the ambient temperature exceeds +40°C, which will cause the temperature of electrical equipment. Raise, affect explosion-proof safety. In addition, long-term operation of electrical equipment at high temperatures can affect the life of electrical insulation materials. If the electrical equipment has a plastic housing, high temperatures will accelerate the aging of the plastic, affecting the operational safety and explosion-proof safety of the equipment.

Other adverse conditions

Sunlight, rain, snow, dust, lightning and other conditions will have adverse effects on explosion-proof electrical equipment. Sunlight can accelerate the photo-aging of insulating materials and plastic shells; rain, snow, and dust can reduce the leakage resistance of the insulating parts, and the dust can also affect the lubrication between relative moving parts (for example, bearings) of the equipment and cause friction. High temperature; Lightning produces an inductive surge voltage on the grid, causing damage to the insulation of electrical equipment. Safety Inspection of Explosion-Proof Electrical Equipment In order to ensure explosion-proof safety and operational safety of explosion-proof electrical equipment, regular and daily inspections and maintenance of in-use explosion-proof electrical equipment and electrical installations should be performed. "Electrical Safety Regulations for Explosive Hazardous Locations" (Trial) and IEC60079-17:2002 "Electrical Equipment for Explosive Gas Environments Part 17: Inspection and Maintenance of Electrical Installations in Hazardous Locations (Excluding Coal Mines)" Operation of Explosion-Proof Electrical Equipment and Electrical Installations And maintenance has been specified in terms of explosion-proof safety.

The inspection level is divided into the following methods and contents:

Visual inspection - the inspection of the apparent defect with the naked eye without the use of inspection equipment or tools, ie routine inspections.

Careful inspection - including visual inspection and inspection using inspection equipment. For example, using a stepladder (necessary place) and/or tool can identify a significant defect inspection. This type of inspection is a professional inspection and should generally be conducted on a regular basis.

One-by-one inspections - including careful inspections and inspections where the apparent defect can only be identified by opening the housing and/or (if necessary) using tools and testing equipment. This inspection is an inspection during the overhaul of equipment.

The inspection type is divided according to the inspection implementation time:

Initial inspection—checks of all electrical equipment, systems, and devices before they are put into operation. It is generally performed in conjunction with the installation acceptance of engineering projects or equipment.

Regular inspections - Routine inspections of all electrical equipment, systems, and devices. Can be carefully checked or checked item by item. Regular inspections are divided into professional inspections and overhaul inspections according to the purpose and contents of inspections. Sampling inspections of some electrical equipment, systems, and devices. The sampling inspection may be a visual inspection, a careful inspection or an item-by-item inspection. The specifications and composition of all sampling samples shall be determined according to the purpose of the inspection. The effects of environmental conditions, vibrations, and inherent defects in the design can be monitored through sampling inspections.

Continuous supervision - Regular maintenance, inspection, maintenance, monitoring and maintenance of electrical equipment by experienced and skilled technicians to keep the explosion-proof performance of the equipment in good condition. According to the characteristics of explosion-proof electrical equipment, reference is made to the inspection item list in IEC 60079-17. The inspection items related to the explosion-proof structure and explosion-proof safety of the explosion-proof, increased-safety, and non-sparking electrical equipment related to the equipment itself are listed in Table 1.

Safety evaluation of explosion-proof electrical equipment

The purpose of inspection of explosion-proof electrical equipment is to evaluate the current status of the equipment, to maintain the equipment in a normal state, and to repair or replace equipment that has failed. On the other hand, through daily inspections or professional inspections, it is possible to detect the precursors of equipment failures through the changes in equipment operating status and take relevant measures in a timely manner to avoid the losses caused by equipment failures. In order to evaluate the results of the examination, the basis for evaluation and judgment should be clearly defined. In order to correctly evaluate the safety of the explosion-proof electrical equipment in use, it is necessary to understand the safety level of the new explosion-proof electrical equipment.

New explosion-proof electrical equipment safety

According to the conditions of combustion and explosion, the three elements of flammable substances (for example, natural gas, gasoline vapor, etc.), oxidants (for example, oxygen in air), and ignition sources (open flame, arc, spark, or high temperature) are only in time and space at the same time. When they meet, it is possible to explode or burn. The installation and use of explosion-proof electrical equipment in explosion hazardous environments aims to prevent electrical equipment from becoming a source of ignition. Explosion-proof electrical equipment in accordance with explosion-proof measures are divided into intrinsically safe explosion-proof type, increased safety and other different types. Taking the explosion-proof type as an example, it is to make a sturdy enclosure for electrical equipment, able to withstand the explosion pressure caused by the explosion inside the enclosure without damage; the gap of all joints of the enclosure is less than the maximum experimental safety clearance of the corresponding flammable gas, if flammable When the gas enters the housing and is ignited by the spark, the explosion flame is confined within the housing and cannot ignite the explosive mixture in the external environment of the housing, thereby ensuring the safety of the environment. The shell is a flameproof shell, and the electrical equipment with a flameproof shell is a flameproof electrical equipment.

Explosion-proof electrical equipment is installed and installed in a dangerous explosion environment. Its explosion-proof safety is directly related to production safety. Therefore, safety assessment of explosion-proof electrical equipment in use in the environment should strictly comply with relevant standards and regulations. In the assessment of specific equipment, it is necessary to consider not only the condition of the equipment itself, but also the conditions of the environment, such as the division of hazardous locations and other conditions of the environment, to achieve safety and economy under the premise of safety. Unite.
