With the advancement of safe cities, the safety of urban communities has been paid more and more attention. Among them, elevator safety is particularly important. As a closed and small public place, the elevator is slightly inadvertent and easy to cause casualties. Therefore, the safety index is very high. It is necessary to monitor the personnel activities and elevator operation in the elevator day and night. Video surveillance Existence is indispensable.
Most of the traditional elevator monitoring systems are wired monitoring systems. The cable monitoring system will wear out in the elevator operation, which needs regular update and maintenance, which increases the cost. Therefore, more and more engineers choose wireless monitoring methods.
Factors affecting elevator monitoring wireless transmission:
The wireless transmission adopts the point-to-point method. A transmission point is installed on the car and a receiving point is installed at the end of the elevator shaft. The data can be freely transmitted while the elevator car is moving, and the bandwidth fully satisfies the high-definition surveillance video transmission.
However, customers are often heard that wireless transmission solutions are not effective, with large delays and poor stability. In fact, not all wireless monitoring devices have poor stability, but do not choose the right product or the problem caused by not paying attention to details during the installation process. This article combines the experience of applying Tengyuan Zhituo wireless bridge to analyze the factors that affect the effect of elevator monitoring wireless transmission system:
1, the camera reason
Poor performance of the camera itself can also result in unclear surveillance images.
2, the choice of wireless monitoring equipment
As we all know, to build a stable wireless monitoring system, wireless monitoring equipment is the most important factor, it is directly related to the transmission performance of the entire system. The environment of the elevator shaft is complicated. The inverter motor and the controller will generate interference signals. This has high requirements for the anti-interference of the monitoring equipment. Therefore, the elevator wireless monitoring equipment is often selected to build the elevator monitoring system.
3. Installation and debugging
The elevator wireless monitoring equipment needs to find a suitable installation position and direction when bridging, and also needs to enter the setting interface to set the bridge. The bridging status of the wireless monitoring equipment and the signal strength of the bridge play a vital role in the monitoring effect. Therefore, it is recommended to install and debug the professional.
