Elevator Monitoring Pains VS Powerline Communication Solution
Elevator Monitoring Pains:
The installation difficulty of the elevator video monitoring for the engineers is mainly due to the difficulty in wiring. Although the wireless bridge scheme commonly used in the market has solved the cabling problem, while the signal is unstable, it is easy to drop wires and lose packets. The effect is not ideal.
Powerline Transmission Solution:
Working principle: Use the original line of the elevator to load the network (TCP/IP protocol) video or other network signals of the terminal equipment such as the camera/digital screen in the car to 7HP200 or 7ZX150, after modulation, through OFDM carrier technology , use the video line of the elevator travelling cables to transmit the signal to another 7ZX150 on the platform on the elevator shaft, and then transmit the video and other signals to the host computer in the monitoring room after modulation and demodulation.
Since 7ZX150 has the function of filtering and anti-interference, it can perfectly solve various strong electromagnetic interference and noises on signal transmission caused by heavy-duty variable-frequency motors from the shaft to the car, strong current switch surges, and high-frequency signal generators during the operation of the elevator. interference to achieve stable signal transmission.
Installation method: Install a 7ZX150 on the platform of the elevator shaft. In the middle, use the elevator travelling cables to find the video cable, install a 7HP200 or 7ZX150 in the car, and connect it with the network camera to achieve the purpose of stably transmitting network video and other signals.
Stable operation and easy installation;
This scheme is not only used for video monitoring, but also for transmission of any data, such as elevator status monitoring/diagnosis, video intercom, equipment signal transmission, etc.
