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. The reasons are nothing more than the following.

First of all, the management department does not pay enough attention to the maintenance of the monitoring system, and thinks that it is not necessary to invest too much manpower, material resources and financial resources, so it ignores the management of the monitoring system facilities in the management process, which leads to the late management and maintenance of the system can not keep up.

Secondly, there is no complete and planned monitoring equipment maintenance implementation plan. There are hundreds of monitoring devices in Shenyang Taoxian International Airport, which are distributed on the first floor, the first floor, the second floor, the second floor and the first floor of the entire terminal. The maintenance of equipment is an arduous and important task. Classify these monitoring devices and make maintenance plans, so that the complicated and tedious work becomes orderly and clear. When a certain equipment breaks down, professional technicians can quickly call out the relevant technical parameters, performance indicators and other relevant information of the equipment and take targeted maintenance measures to effectively improve the maintenance efficiency of the equipment.

Third, the cost performance of monitoring equipment is considered too much in the procurement, while the maintenance of monitoring system and equipment is neglected. There are too many brands of monitoring equipment, too many product suppliers, and the after-sales guarantee measures of manufacturers are not in place, which leads to the continuous failure of monitoring equipment after a period of use and the rising damage rate. Finally, the original equipment has to be updated in a large area, resulting in repeated investment and serious waste.

Maintenance method of monitoring equipment

In order to maintain the monitoring equipment, the maintenance center is equipped with corresponding manpower and material resources (tools, communication equipment, etc.). ), responsible for the daily monitoring, maintenance, service and management of the monitoring system, and undertake equipment maintenance services to ensure the long-term, reliable and effective operation of the monitoring system.

1, maintain basic conditions

As the saying goes, "a clever woman can't cook without rice" is the same for the maintenance of monitoring system. 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 are available.

Generally speaking, the maintenance of each system should establish a corresponding spare parts library, which mainly stores some important equipment that is not easy to repair immediately after damage, such as cameras, lenses, monitors and so on. 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 meet the requirements

Accessories are mainly the extra configuration of various discrete components and modules in the equipment, which can be prepared more, 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 test instruments should be in good condition.

In order to maintain the equipment frequently, it is necessary to configure common maintenance tools and instruments, such as pliers, screwdrivers, measuring pens, soldering irons, adhesive tapes, multimeters and oscilloscopes. Buy it at any time when necessary, and make your own simulated load as a test tool when necessary.

2, some matters needing attention in equipment maintenance

In the maintenance process of monitoring system equipment, it is necessary to take precautions against some situations and make the equipment run normally as much as possible, mainly including moistureproof, dustproof, anticorrosion, lightning protection and interference prevention.

1) moistureproof, dustproof and anticorrosive

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 mechanical and electrical system maintenance 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, when maintaining monitoring equipment, we must attach great importance to lightning protection. 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 separation of 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.

3. Details are as follows:

I Dust and clean the equipment once every quarter, and clean the dust exposed by the monitoring equipment. Remove the camera, protective cover and other components for thorough dust removal, and then clean each lens with anhydrous alcohol cotton to adjust the definition, so as to prevent dust from being sucked into the monitoring equipment body due to factors such as machine operation and static electricity, and ensure the normal operation of the machine. At the same time, check the ventilation, heat dissipation, dust removal and power supply facilities in the monitoring room. The outdoor temperature should be -20℃ ~+60℃ and the relative humidity should be 10% ~ 100%. The indoor temperature should be controlled at +5℃ ~+35℃ and the relative humidity should be controlled at 10% ~ 80%, so as to leave a good running environment for the monitoring equipment in the computer room.

Two. According to the operation instructions of each part of the equipment in the monitoring system, check its technical parameters and transmission line quality of the monitoring system every month, deal with hidden dangers, assist the monitoring supervisor to set the use level and other data, and ensure that all parts of the equipment function well and can run normally.

Three. Conduct a comprehensive inspection on the aging parts of monitoring equipment once a month, and replace and repair them in time once aging phenomena are found, such as video heads.

Four. Regularly clean the parts that are easy to absorb dust every quarter. If the display is exposed to the air, a large amount of dust will be adsorbed on the surface of the display due to the electrostatic effect of the screen, which will affect the clarity of the picture. Wipe the monitor regularly and check the color and brightness of the monitor.

Verb (abbreviation of verb) carries out maintenance on the monitoring equipment that works for a long time once a month. Hard disk video recorder will generate more heat if it works for a long time. Once its electric fan fails, it will affect the heat dissipation, thus avoiding the abnormal work of the hard disk video recorder.

Intransitive verbs monitor the operation of monitoring systems and equipment, analyze the operation situation, and find and eliminate faults in time. Such as network equipment, server systems, monitoring terminals and various terminal peripherals. Running check of desktop system, virus defense of network and desktop system.

Seven. Optimize the monitoring system and equipment regularly every month: reasonably arrange the monitoring network requirements of the monitoring center, such as bandwidth and IP address restrictions. Provide monthly monitoring system network performance test, including network connectivity, stability and bandwidth utilization; Real-time detection of all foreign network attacks that may affect the monitoring network equipment, real-time monitoring of the running status, traffic and intrusion monitoring of each server. Check the abnormal situation and handle it. Plan and optimize the monitoring network according to the needs of users; Assist to deal with server hardware and software failures and remove related hardware and software.

Eight. Provide regular information service once a month: on the first working day of each month, submit the record of last month's emergency repair, repair and maintenance to the person in charge of the monitoring center in the form of electronic documents.
