For a long time, due to the monitoring system maintenance is not emphasized, resulting in a lot of monitoring equipment has just been put into use on the damage, the reason is no more than the following points.
First of all, the management of the monitoring system maintenance work is not enough attention, that there is no need to invest too much manpower, material and financial resources, and therefore neglected in the management process of the monitoring system facilities management, resulting in the system's post-management and maintenance to keep up.
Secondly, there is not a complete, planned monitoring equipment maintenance implementation program. Shenyang Taoxian International Airport, the number of monitoring equipment up to hundreds of units, and distributed throughout the terminal building of the first floor, first floor mezzanine, the second floor, as well as the second floor of the mezzanine and the first floor, the maintenance of the equipment is an arduous and important work, these monitoring equipment classified and formulated the maintenance program, the complex and cumbersome work to become structured and clear. When a certain equipment failure, professional technicians can quickly call out the equipment related technical parameters, performance indicators and other relevant information, and take targeted maintenance measures to effectively improve the efficiency of equipment maintenance.
Thirdly, the procurement of monitoring equipment is too much consideration of the cost-effectiveness of the equipment and ignore the monitoring system and equipment maintenance and repair. Monitoring equipment brand too many, too many product suppliers, manufacturers of after-sales protection measures are not in place and so on, leading to the use of monitoring equipment for a period of time, equipment failures, the damage rate continues to rise, and ultimately had to carry out a large area of the original equipment to update the phenomenon of duplication of investment, wastefulness and severity of the phenomenon.
Monitoring equipment maintenance methods
In order to do a good job of monitoring equipment maintenance, maintenance centers equipped with the appropriate manpower, material resources (tools, communication equipment, etc.), responsible for the daily monitoring of the monitoring system monitoring, maintenance, service, management, to assume responsibility for the maintenance of the equipment and services, in order to ensure that the monitoring system for long-term, reliable and effective operation.
1, the basic conditions of maintenance
The old saying goes, "a clever woman can't cook without rice", the same reason for the maintenance of the monitoring system is also the same reason for the monitoring system to carry out normal maintenance of equipment required for the maintenance of the basic conditions of the monitoring system, that is, to do "four Qi "that is, spare parts, accessories, tools, instruments, Qi.
1) spare parts Qi
In general, the maintenance of each system must establish a corresponding spare parts library, the main reserve of some of the more important and damage is not easy to repair immediately after the equipment, such as cameras, lenses, monitors and so on. Once the failure of these devices may make the system can not be normal operation, must be replaced in a timely manner, so there must be a certain number of spare parts, and spare parts library inventory must be based on whether the equipment can be repaired and the characteristics of the equipment's operating cycle is constantly being updated.
2) Accessories
Accessories are mainly a variety of discrete components in the device and the additional configuration of the module, you can prepare more, mainly for the maintenance of equipment. Commonly used accessories are mainly circuit required by a variety of integrated circuit chips and a variety of circuit discrete components. Other larger equipment will have to configure certain functional modules for emergency use. In this way, after maintenance can produce good benefits with a small investment, saving a lot of money to update equipment.
3) tools and testing instruments Qi
To do diligently repair equipment, it must be configured with commonly used maintenance tools and overhaul instruments, such as a variety of pliers, screwdrivers, electric pens, soldering irons, tape, multimeters, oscilloscopes, and so on, and when needed should be added at any time, and if necessary, should also be made such as analog loads as a test tool.
2, some of the precautions in the maintenance of equipment
In the monitoring system equipment maintenance process, should be prevented in some cases, as far as possible, so that the normal operation of the equipment, the main need to do a good job of moisture, dust, corrosion, lightning, and anti-interference work.
1) Moisture, dust, corrosion
For a variety of monitoring system acquisition equipment, as the equipment is directly placed in a dusty environment, the operation of the equipment will have a direct impact on the need to focus on moisture, dust, corrosion maintenance work. Such as cameras hanging in the shed for a long time on the end of the shield and dust glass will soon be covered with a layer of dust, carbon dust and other mixtures, dirty and black, but also corrosive, seriously affecting the effect of viewing, but also to the damage to the equipment, so you must do a good job of the camera's dust, corrosion maintenance work. In some places where moisture is heavy, it must be in the maintenance process on the installation location, the protection of equipment to adjust to improve the equipment itself to prevent moisture, while the high humidity zone should often take dehumidification measures to solve the moisture problem.
2) Lightning, anti-interference
As long as the people engaged in the maintenance of electromechanical systems are aware of the thunderstorms, the equipment is often struck by lightning, to monitor the normal operation of the equipment caused by a great deal of security risks, therefore, the monitoring equipment in the maintenance process must be a high degree of attention to the issue of lightning. Lightning measures are mainly to do a good job of equipment grounding lightning ground network, should be done according to the equipotential body program to do a good job of independent ground resistance less than 1 ohms of the integrated grounding network, to put an end to the weak system of lightning grounding and power lightning grounding network mixed with the practice of preventing the power grounding network clutter on the equipment to produce interference. Anti-interference is mainly to do when the wiring should adhere to the principle of separation of strong and weak power, power cables and communication cables and video cables are separated, in strict accordance with the communications and power industry wiring specifications for construction.
3, as follows:
I. Quarterly equipment dust, cleaning, sweeping the monitoring equipment exposed dust, the camera, the shield and other components should be unloaded thoroughly blowing dust, and then use anhydrous alcohol cotton to wipe the lens clean, adjust the clarity, to prevent the machine from running, static electricity and other factors will be dust inhaled into the body of the monitoring equipment to ensure that the machine operates normally. At the same time, check the monitoring room ventilation, cooling, dust, power supply and other facilities. Outdoor temperature should be -20 ℃ ~ +60 ℃, relative humidity should be 10% ~ 100%; indoor temperature should be controlled at +5 ℃ ~ +35 ℃, relative humidity should be controlled at 10% ~ 80%, leaving the room to monitor the equipment a good operating environment.
II. According to the instructions for each part of the monitoring system equipment, monthly testing of its technical parameters and monitoring system transmission line quality, dealing with hidden faults, and assisting the supervisor to set up the monitoring level and other data, to ensure that each part of the equipment is functioning well, and can be operated normally.
III. For easy aging of the monitoring equipment components once a month to carry out a comprehensive inspection, once found that the aging phenomenon should be replaced in a timely manner, maintenance, such as video head.
IV. easy to absorb dust part of the regular quarterly clean-up, such as the monitor is exposed to the air, due to the electrostatic effect of the screen, there will be a lot of dust is adsorbed on the surface of the monitor, affecting the clarity of the picture, to regularly wipe the monitor, the monitor to calibrate the color and brightness.
V. Regular monthly maintenance of monitoring equipment for long periods of time, such as hard disk recorders work for a long time will produce more heat, once its electric fan has a fault, it will affect the heat exhaust, so as to avoid the hard disk recorder does not work properly.
VI. monitoring system and equipment operation to monitor, analyze the operating situation, timely detection and troubleshooting. Such as: network equipment, server systems, monitoring terminals and various terminal peripherals. Desktop system operation check, network and desktop system virus defense.
VII. Regular monthly optimization of monitoring system and equipment: Reasonable arrangement of monitoring center monitoring network requirements, such as bandwidth, IP address and other restrictions. Provide monthly monitoring system network performance testing, including network connectivity, stability and bandwidth utilization, etc.; real-time detection of all external network attacks that may affect the monitoring network equipment, real-time monitoring of the operating status of each server, traffic and intrusion monitoring. For abnormal situations, verification and related processing. According to the user needs to monitor the network planning, optimization; to assist in dealing with server hardware and software failure and related hardware and software disassembly and installation.
VIII. Provide regular information service once a month: on the first working day of each month, report the record sheet of the previous month's emergency repairs, repairs, maintenance, and upkeep to the person in charge of the monitoring center in the form of an electronic document.
