What are the maintenance methods of monitoring equipment?

As the old saying is good, “The clever woman is hardly a straw without rice”. The same is true for the maintenance of the monitoring system. The basic maintenance conditions required for the normal equipment maintenance of the monitoring system are the “four equals”, that is, the spare parts. , Accessories Qi, tools Qi, instruments Qi.

In general, each system must maintain a corresponding spare parts store for its maintenance. It mainly stores some equipment that is more important and can't be repaired immediately after damage, such as cameras, lenses, and monitors. Once these devices fail, they may cause the system to fail to operate properly and must be replaced in time. Therefore, a certain number of spare parts must be available, and the inventory of the spare parts library must be constantly updated according to the characteristics of the equipment's ability to maintain and operate the equipment.

The accessories are mainly the additional configuration of various discrete components and modules in the equipment, and can be prepared for more, mainly used for equipment maintenance. The commonly used accessories include various integrated circuit chips and various circuit discrete components required for the circuit. Other larger devices must be equipped with certain functional modules for emergency use. In this way, after maintenance, small investments can be made to produce good benefits, saving a lot of money for updating equipment.

To repair equipment, you must configure common maintenance tools and maintenance equipment, such as various pliers, screwdrivers, pencils, soldering irons, tapes, multimeters, oscilloscopes, etc. If necessary, you should also add them at any time. Make your own simulation load as a test tool.

During the maintenance of the monitoring system equipment, some situations should be guarded against as far as possible so that the equipment can operate normally. The main work is to prevent moisture, dust, corrosion, lightning and interference.

For various collection equipments of the monitoring system, since the equipment is directly placed in a dusty environment, the operation of the equipment will have a direct impact, and it is necessary to focus on the maintenance of moisture, dust, and corrosion. If the camera is hung on the shed for a long time, the protective cover and the dustproof glass will be quickly covered with a mixture of dust, carbon ash, etc., dirty and black, and also corrosive, seriously affecting the viewing effect, also to the equipment To damage, so you must do a good job of camera dust, corrosion protection and maintenance work. In some places where the humidity is heavy, the installation position and equipment protection must be adjusted during the maintenance to increase the moisture resistance of the equipment. At the same time, dehumidification measures must be taken to solve the moisture problem in high humidity areas.

As long as people who have engaged in the maintenance work of electromechanical systems know that thunderstorms and lightning strikes are a common occurrence and cause great safety risks to the normal operation of monitoring equipment. Therefore, monitoring equipment must be protected against lightning during the maintenance process. highly valued. The measures of lightning protection are mainly to make the equipment grounding lightning protection ground network, should be based on the equipotential body program to do an independent grounding resistance less than 1 ohm of the integrated grounding network, to eliminate the lightning protection system grounding and power lightning protection grounding network Mixed practices to prevent power ground grid clutter from interfering with equipment. Anti-interference is mainly to adhere to the principle of separation of strong and weak electricity when wiring, separate the power cable from the communication cable and the video cable, and strictly follow the wiring and construction specifications of the communication and power industry.

1. Dust removal and cleaning of the equipment every quarter, sweeping the dust exposed by the monitoring equipment, thoroughly removing dust from the camera, protective cover and other parts, and then wiping the lens clean with anhydrous alcohol to adjust the resolution to prevent Due to machine operation, static electricity and other factors, dust is sucked into the monitoring device body to ensure normal operation of the machine. At the same time check the monitoring room ventilation, cooling, clean dust, power supply and other facilities. Outdoor temperature should be -20 °C ~ +60 °C, relative humidity should be 10% to 100%; indoor temperature should be controlled at +5 °C ~ +35 °C, relative humidity should be controlled at 10% ~ 80%, leaving a good monitoring room equipment Operating environment.

2. According to the instructions for use of each part of the monitoring system, monthly check its technical parameters and the quality of the transmission line of the monitoring system, handle hidden troubles, assist supervisory supervisors to set various data such as usage level, and ensure that each part of the equipment The item is well-functioning and can operate normally.

3. Perform comprehensive inspections on components that are prone to ageing once a month, and replace them once they are found to be aging, such as video heads.

4. Clean the easy-to-vacuum part once every quarter. If the monitor is exposed to air, due to the electrostatic effect of the screen, there will be a lot of dust adsorbed on the surface of the monitor, affecting the clarity of the picture. Regularly wipe the monitor. , proofread the color and brightness of the monitor.

5. The monitoring equipment that works for a long time is regularly maintained once a month. For example, if the hard disk recorder is working for a long time, it will generate more heat. Once the fan has a fault, it will affect the heat discharge, so as to prevent the hard disk recorder from working abnormally.

6. Monitor the operation status of the monitoring system and equipment, analyze the operation status, and find and eliminate faults in time. Such as: network equipment, server systems, monitoring terminals and various terminal peripherals. Check the running of the desktop system and virus defense of the network and desktop systems.

7. The monthly monitoring system and equipment are optimized regularly: The monitoring network needs of the monitoring center are reasonably arranged, such as bandwidth, IP address and other restrictions. Provide monthly monitoring of network performance of the surveillance system, including network connectivity, stability, and utilization of bandwidth; real-time detection of all external network attacks that may affect monitoring network devices, real-time monitoring of server operating status, traffic, and intrusion monitoring Wait. Check the abnormal situation and perform relevant processing. According to the needs of the user, the planning and optimization of the monitoring network will be carried out; the failure of the server hardware and software and the disassembly and assembly of the relevant hardware and software will be assisted.

8. To provide monthly regular information service: On the first working day of the month, the emergency repair, maintenance, maintenance, and maintenance records of the previous month shall be submitted to the person in charge of the monitoring center in the form of an electronic document.
