Some precautions in the maintenance of explosion-proof camera equipment

During the maintenance of the explosion-proof monitoring system equipment, some situations should be prevented to ensure that the equipment runs as normal as possible. The main work is to prevent moisture, dust, corrosion, lightning, and interference.

1) moisture-proof, dust-proof and anti-corrosion

For various acquisition equipment of explosion-proof monitoring system, because the equipment is directly placed in a dusty environment, it will have a direct impact on the operation of explosion-proof equipment, and it is necessary to focus on the maintenance work against moisture, dust and corrosion. If the explosion-proof camera is hung from the shed for a long time, the explosion-proof shield and explosion-proof glass will soon be covered with a layer of dust, carbon ash, etc., which is dirty and black, and also corrosive, which seriously affects the viewing effect and also gives explosion protection. The equipment brings damage, so the dustproof and anticorrosive maintenance work of explosion-proof cameras must be done well. In some places with heavy moisture, the installation position and equipment protection must be adjusted during the maintenance process to improve the equipment's moisture resistance. At the same time, dehumidification measures must be taken frequently in high-humidity zones to solve the problem of moisture resistance.

2) Lightning and interference prevention

As long as anyone who has been engaged in the maintenance of electromechanical systems knows that lightning strikes are common when thunderstorms occur, which causes great safety risks for the normal operation of explosion-proof monitoring equipment. Therefore, explosion-proof monitoring equipment must be protected during the maintenance process. The issue of lightning protection is highly valued. The lightning protection measures are mainly to implement a lightning protection grounding network for equipment grounding. An integrated grounding network with a ground resistance of less than 1 ohm should be prepared according to the equipotential scheme to prevent the lightning protection grounding of the weak electrical system and the power lightning protection grounding network. Mixed practices to prevent power ground grid clutter from interfering with equipment. The anti-interference principle is to adhere to the principle of separation of strong and weak electricity when wiring, separate power cables from communication cables and video cables, and strictly follow the wiring specifications of the communications and power industries.

3. The details are as follows:

1) Dust removal and cleaning of the equipment once a quarter, clean up the dust exposed by the explosion-proof monitoring equipment, remove the explosion-proof cameras, explosion-proof shields and other components to thoroughly blow off the dust, and then wipe each lens with anhydrous alcohol cotton to adjust the clarity To prevent dust from being drawn into the body of the explosion-proof monitoring equipment due to machine operation, static electricity, and other factors to ensure the normal operation of the machine. At the same time, check and monitor the ventilation, heat dissipation, dust cleaning, and power supply facilities in the equipment room. The outdoor temperature should be -20 ℃ ～ + 60 ℃, the relative humidity should be 10% ～ 100%; the indoor temperature should be controlled at + 5 ℃ ～ + 35 ℃, and the relative humidity should be controlled between 10% ～ 80%. It is left to the computer room for monitoring. The equipment has a good operating environment.

2) According to the instructions for the use of various parts of the explosion-proof monitoring system, monthly check its technical parameters and the quality of the transmission line of the explosion-proof monitoring system, handle the hidden troubles, assist the supervisor in setting various data such as the use level, and ensure that each part All functions of the equipment are good and can run normally.

3) Fully inspect the parts of the explosion-proof monitoring equipment that are easy to deteriorate once a month, and replace and repair them in time if aging phenomena are found, such as video heads.

4) Clean the dust-prone parts regularly every quarter. For example, if the explosion-proof monitor is exposed to the air, due to the electrostatic effect of the screen, a lot of dust will be adsorbed on the surface of the explosion-proof monitor, which will affect the clarity of the screen, and it should be wiped regularly. Explosion-proof monitor, proof color and brightness of explosion-proof monitor.

5) The explosion-proof monitoring equipment for long-term work is regularly maintained once a month. For example, if the hard disk video recorder works for a long time, it will generate more heat. Once its electric fan fails, it will affect the heat dissipation and prevent the hard disk video recorder from working abnormally.

6) Monitor the operation of the explosion-proof monitoring system and equipment, analyze the operation, and find and troubleshoot in a timely manner. Such as: network equipment, server systems, monitoring terminals and various terminal peripherals. Desktop system operation check, network and desktop system virus defense.

7) Regularly optimize the explosion-proof monitoring system and equipment every month: Reasonably arrange the monitoring network requirements of the monitoring center, such as bandwidth, IP address and other restrictions. Provides monthly network performance testing of explosion-proof monitoring systems, including network connectivity, stability, and bandwidth utilization; real-time detection of all external network attacks that may affect explosion-proof monitoring network equipment, real-time monitoring of the server operating status, traffic, and Intrusion monitoring and more. Check the abnormal situation and deal with it. Plan and optimize the monitoring network according to user needs; assist in handling server software and hardware failures, and disassemble and install related hardware and software.

8) Provide regular information service once a month: On the first working day of each month, submit the repair, repair, maintenance, and maintenance record form of the previous month to the person in charge of the monitoring center in the form of an electronic file.
