Wireless monitoring equipment common problems and solutions
It is inevitable that wireless monitoring equipment will encounter some common problems and failures during the operation of the wireless monitoring equipment . Users who do not understand the product knowledge will not be able to handle it by themselves. Today, Tengyuan Zhituo Xiaobian has listed some common wireless monitoring equipment common problems and solutions for everyone, so that the users can use the equipment better. The problems that often occur with wireless monitoring devices are the following types.
First, the quality of the product itself
This situation occurs mostly on decoders, electric gimbals, and transmission components. The solution to the equipment product quality problem is to replace the product instead of disassembling and repairing it.
Second, the incorrect connection between devices usually has the following aspects
1, the impedance does not match
2. Communication interface or communication mode does not correspond.
3, the drive capacity is not enough or exceed the specified number of device connections.
Solution: Reconnect the device according to the operating instructions.
Third, the appearance of wood grain interference on the monitor.
There are many reasons for this failure. There are roughly the following reasons:
1. The quality of the video transmission line is not good, and the shielding performance is poor. At the same time, the line resistance of such a video line is too large, which causes the signal to be greatly attenuated and is also the cause of the increased failure. If this type of reason is determined, the solution is to replace the cable that meets the requirements.
2, because the power supply system is not "clean"
The fact that the power supply is not "clean" means that an interference signal is superimposed on a normal power supply (50-week sine wave). This type of interference signal on the power supply is mostly caused by high-current, high-voltage SCR devices in the power grid. The solution to this situation is relatively simple. It can be eliminated by simply using a clean power supply or an online UPS for the entire system.
3. There are strong interference sources near the wireless monitoring system that cause the influence on the transmission signal. The solution can be judged through investigation and understanding. If this is the reason, it is necessary to strengthen the shielding of the front-end and central equipment, as well as to ground the pipelines of the video cable.
Fourth, the transmission of image clarity is not high, data loss, color saturation is too small.
This situation may be due to the fact that the transmission distance is too long, and there is no relay amplification device in the middle; or because the distribution capacitance of the video transmission cable is too large; or because of the convergence between the core and shielded wires of the transmission line in the transmission link. The distribution of the equivalent capacitance.
The above is about the common faults and solutions of wireless monitoring equipment. If it is not detailed enough, users are welcome to pay attention to the website of Tengyuan Zhituo.
