How to do a good job in monitoring fire smoke exhaust equipment.

For a long time, due to the neglect of the maintenance of the monitoring system, many monitoring equipment was damaged just after it was put into use. In order to maintain the monitoring equipment, the maintenance center is equipped with corresponding manpower and material resources (tools, communication equipment, etc.). ) Be responsible for the daily monitoring, maintenance, service and management of the monitoring system, and undertake the maintenance service of equipment to ensure the long-term, reliable and effective operation of the monitoring system. 1, basic maintenance conditions As the saying goes, "A clever woman can't cook without rice", the same is true for the maintenance of monitoring systems. The basic maintenance condition for normal equipment maintenance of monitoring system is "four neat", that is, spare parts, accessories, tools and instruments are clean and tidy. 1) spare parts collection Generally speaking, a corresponding spare parts library should be established for the maintenance of each system, which mainly stores some important equipment that is not easy to be repaired immediately after being damaged, such as cameras, lenses, monitors, etc. Once these devices fail, the system may not work normally and must be replaced in time. Therefore, there must be a certain number of spare parts, and the inventory of spare parts warehouse must be constantly updated according to whether the equipment can be maintained and the characteristics of the equipment operation cycle. 2) Accessories are mainly the extra configuration of various discrete components and modules in the equipment, and more can be prepared, which is mainly used for equipment maintenance. Commonly used accessories mainly include various integrated circuit chips and various circuit discrete components required by circuits. Other large equipment must be equipped with certain functional modules in case of emergency. After this maintenance, it can produce better benefits with less investment and save a lot of money for updating equipment. 3) Tools and testing instruments In order to maintain the equipment frequently, commonly used maintenance tools and instruments, such as pliers, screwdrivers, measuring pens, soldering irons, tapes, multimeters, oscilloscopes, etc. , if necessary, it should be added at any time, and if necessary, it should also make its own simulated load as a test tool. 2, some precautions in equipment maintenance In the maintenance process of monitoring system equipment, it is necessary to prevent some situations as much as possible to make the equipment run normally, mainly to do a good job of moisture-proof, dust-proof, anti-corrosion, lightning protection and anti-interference. 1) Moisture-proof, dust-proof and anti-corrosion For all kinds of acquisition equipment in the monitoring system, because the equipment is directly placed in a dusty environment, it will have a direct impact on the operation of the equipment, and it is necessary to focus on the maintenance of moisture-proof, dust-proof and anti-corrosion. If the camera is hung at the end of the shed for a long time, the protective cover and dustproof glass will be covered with a layer of dust, carbon ash and other mixtures, which are dirty, black and corrosive, seriously affecting the viewing effect and damaging the equipment. Therefore, it is necessary to do a good job in dustproof and anticorrosive maintenance of the camera. In some places with high humidity, it is necessary to adjust the installation position and equipment protection during maintenance to improve the moisture-proof ability of the equipment itself, and at the same time, dehumidification measures should be taken frequently in high humidity areas to solve the moisture-proof problem. 2) Lightning protection and interference prevention As long as anyone who has been engaged in the maintenance of electromechanical systems knows, it is common for equipment to be struck by lightning when thunderstorm weather comes, which brings great security risks to the normal operation of monitoring equipment. Therefore, monitoring equipment must attach great importance to lightning protection in the maintenance process. Lightning protection measures are mainly to do a good job of lightning protection grounding network for equipment grounding, and to make an independent comprehensive grounding network with grounding resistance less than 1 ohm according to the equipotential body scheme to prevent the lightning protection grounding of weak current system from being mixed with the lightning protection grounding network of power, and to prevent the interference of power grounding network clutter on equipment. Anti-interference is mainly to adhere to the principle of separating strong and weak electricity when wiring, separate power cables from communication cables and video cables, and strictly follow the wiring specifications of communication and power industries.
