閉路電視監工系統中傳輸信號類型有兩種:模擬視頻信號和數字信號。造成干擾的原因主要有

1.各種高頻噪聲;

2.地電位不等;

3.平衡傳輸線路失衡;

4.傳輸線上阻抗不匹配

5.靜電放電沿傳輸線進入設備造成接口芯片損傷或損壞。

一般來說,選擇合適的監控系統供電方式能有效抗干擾。監控系統供電方式有:集中供電和分佈式供電,從抗干擾效果來抗,集中供電方式較好,能消除各處參考電位不等的情況。

Causes of interference from the monitoring system

There are two types of transmission signals in CCTV supervisory systems: analog video signals and digital signals. The main causes of interference are

1. Various high frequency noise;

2. The ground potential is not equal;

3. Balanced transmission line imbalance;

4. Impedance mismatch on the transmission line

5. Electrostatic discharge enters the device along the transmission line, causing damage or damage to the interface chip.

In general, choosing the appropriate monitoring system power supply mode can effectively resist interference. The power supply modes of the monitoring system are: centralized power supply and distributed power supply. The anti-interference effect is resistant, and the centralized power supply mode is better, which can eliminate the situation where the reference potentials are different.
