Many enterprises in the computer room installed monitoring system, began to enter the trial run phase and delivery, in the use of the process may be a failure phenomenon. These failures can affect the normal operation of the system or the overall performance and quality is not ideal. So how do you deal with these common problems? Shenzhen Ji Tong today to tell you about eight of the problems of fault!
Some lines connected to the monitoring host, if improperly handled, can cause disconnection, short circuiting, poor insulation between wires, faulty cabling and other equipment (or parts) damaged, degraded performance or the equipment itself is not damaged, but reflects the phenomenon exists in electronic equipment or components, especially some connectors of poor quality, Poor cabling technology is also a common cause of problems.
Solution: In this case, we need to analyze calmly according to the phenomenon of fault, and judge that the fault phenomenon is caused by the connection of some lines on several lines, so that the scope of the problem can be reduced. For example, a camera with a three-variable lens image signal is normal, but the lens can not be controlled without having to check the video output line and just check the lens control cable.
Second, the computer room monitoring host or the component itself quality is carefully screened out, has been commercialized equipment or components should not appear quality problems.
Workaround: Even if the problem usually occurs after the system has been delivered and has been running for quite a long time, the most common problem in addition to the above-mentioned product quality problem is due to improper adjustment of the equipment. For example, the adjustment of the rear intercept of the camera is a very detailed and precise work, such as the failure to carefully adjust the focus will be poor or in the three variable lens of the various operations of defocus and other issues. In addition, the position of some switch and adjustment knob on the camera is correct, whether it meets the technical requirements of the system, the correct setting of the XXX code switch or other adjustable parts will directly affect the normal use of the device itself or affect the normal performance of the whole system.
Three, the distance too far when the operation of the keyboard can not be xxx on the camera (including lens) and gimbal remote control
Workaround: This is mainly because the distance is too far, the control signal attenuation is too large and the XXX connection is too weak control signal caused. At this point should be installed at a certain distance of the relay box to enlarge the XXX control signal.
Four, the monitor image contrast is too small and the image is light
Workaround: This phenomenon if not the control of the host and the monitor itself is the transmission distance or the video transmission line attenuation is too large. In this case, the line amplification and compensation device should be added.
Five, the image clarity is not high, the details are missing, serious when the color signal loss or color saturation through the small
Solution: This is due to the high-frequency loss of the image signal is too large, so that the frequency of more than 3MHz signal loss caused by the basic. This is due to the transmission distance too far and the middle without amplification compensation device, or because the video transmission cable distribution capacitance is too large, or because the transmission link in the transmission line between the core and the shielding line has a concentrated distribution of equivalent capacitance caused.
VI, computer room monitoring tone distortion
Workaround: This is a long-distance video baseband transmission mode prone to the phenomenon of failure. The main reason is caused by the transmission line caused by the high frequency of the signal phase shift too large. This condition should be combined with a phase compensator.
Seven, the computer room monitoring communication bad fault
Solution: The performance of the controlled gimbal or motorized lens can sometimes be normal operation, sometimes not (or delay) action, or after the action is not able to stop after the communication line has a problem.
Viii. failure caused by improper use of power supply
Solution: The power supply is incorrect may be the power supply line or supply voltage is not correct, power is not enough, the transmission line of the electricity supply system short circuit, open circuit, instantaneous overvoltage, etc., especially due to power supply error or transient overvoltage caused by equipment damage.
