Briefly explain the causes and solutions of wireless monitoring signals being interfered

In the wireless monitoring scheme, signal interference is an important factor that has long plagued the stable transmission of wireless monitoring. However, among many wireless monitoring solutions, some equipment vendors can avoid the problem of wireless monitoring signal interference. Today, Tengyuan Zhituo Xiaobian will share the reasons and avoidance methods of wireless monitoring signal interference.

1. Similar equipment interference

Avoid surrounding similar equipment or signal interference with the same equipment. The signal source of such an interference signal may be a normal signal source in our system. It may be that the receiving end does not receive the signal or receives the same signal due to the same frequency or similar, making the receiving terminal difficult to recognize. In this case, we can adjust the frequency of the wireless device, choose a clean channel, or change the position of the wireless device transmitter or receiver to open the distance between the devices.

2. Building interference

Buildings have a debilitating effect on the transmission of wireless signals. When a wireless signal passes through any object, its electrical frequency signal will be refracted to some extent, causing a certain change in its transmission direction, and will cause reflection and attenuation of the signal. If a metal object is encountered during propagation, the attenuation of the signal is also increased. Therefore, when selecting the installation position of the wireless device, the middle is unobstructed as much as possible, and the transmitting end is visible to the middle of the receiving end, thus avoiding the attenuation of the microwave signal, and the monitoring center can receive the high-intensity wireless signal, thereby improving Monitor the effect.

Of course, not all devices interfere with wireless, such as mobile, Unicom towers, walkie-talkies, etc., which have no effect on wireless microwave devices. In the case of interference sources, we can adjust the frequency of the device or choose to install it far away from the interference source, thus greatly reducing the interference to the wireless microwave device.

In addition, to reduce the interference of wireless monitoring signals, the quality of wireless monitoring equipment is also very important. For example, Tengyuan Zhituo has 13 years of experience in R&D and application of wireless monitoring equipment. The company's wireless monitoring equipment uses imported Qualcomm chips and has industrial grades above IP67. Quality, anti-interference, high bandwidth and so on.
