Common problems in monitoring engineering
Monitoring engineering is now around everywhere, whether it is the park, banks, elevators, factories, companies, campuses, and so on are all need to monitor the motivation, so we must monitor the equipment.
1, power supply is not properly triggered by the failure of equipment. Power supply is not correct or roughly as follows: power supply line or power supply voltage is not correct, power is not enough (or the power supply line is not enough, the pressure is too large, etc.), power supply system of short circuit, open circuit, transient over-voltage, etc.. Especially in the case of the power supply error or transient over-voltage caused by the damage of the device into the case. Therefore, before the power supply in the system debugging, we must seriously, strictly check and inspection, must not let down.
2, because some devices (such as those with three variable lens camera and PTZ) links there are many, if not handled properly, especially connected with the equipment line processing is not good, there will be open circuit, short circuit, the line between poor insulation, wiring error as a result of equipment damage, the decline in performance problems. In this case, we should analyze according to the phenomenon of failure, and judge the connection of the line which is caused by the problem that the fault is caused. This will narrow the scope of the problem. Of particular note is that of PTZ cameras due to a full range of motion, a long time, causing interconnect shedding and brake is common. Therefore, special attention should be paid to the connection of the equipment and all kinds of lines should be in accordance with the requirements of the long running. 1 D) w ^8 "W3 O+ D}9
3, the quality of the equipment or components themselves. In theory, all kinds of equipment and components are likely to have quality problems. But from the point of view of experience, is purely the product itself quality problems occurred in the decoder, electric pan, transmission parts and other equipment. It is worth pointing out that some of the equipment from the overall quality may not appear to be unable to use the problem, but from some technical indicators, but not to give the product specification. Therefore, it is necessary to carry out the sampling inspection of the selected products. When it is indeed a product quality problems, the best way is to replace the product, and should not disassemble the repair. In addition, the most common problems due to improper adjustment of equipment. Such as camera and intercept adjustment is a very meticulous and precise work, if not carefully adjusted, there will be out of focus or in three variable lens of various operations occur scattered focal problems. In addition, the camera on the number of switches and adjust the position of the knob is correct, whether it is in line with the technical requirements of the system, the decoder encoding switch or other adjustable parts of the correct or not will directly affect the normal use of the device itself or affect the normal performance of the whole system this text by Shaanxi Electric Communication Technology Co., ltd..
