In the automatic control system of the heat exchange station, the video monitoring system is an important unattended auxiliary means. Each heat exchange station is equipped with 2 cameras with night vision infrared function, a hard disk recorder, and borrows the router of the local control system. , Remotely transmit the video signal to the remote monitoring service center through the network.
The two cameras are respectively aimed at the entrance door of the heat exchange station and the heat exchange unit. The camera on the door can record who has entered the heat exchange station and when it was stolen; whether it is against the camera of the unit can see whether the device has The molecular beam epitaxy of water leakage, steam leakage and fire, etc., take effective measures early to prevent the loss from expanding. Video surveillance extends people's vision, reduces vehicle fatigue, saves time, improves work efficiency, and can store abnormal events, which is helpful for the analysis of accident causes.
The remote service center is composed of two servers: one manages the monitoring data of each heat exchange station; the other collects video signals. Professional software is installed on each of these servers. In addition to collecting and displaying information, the system also has to store important data. Therefore, the hard disk size and redundancy of the server have high requirements. The DELL server is selected in the application. Ensure long-term normal operation.
The service center and the heat exchange station can communicate in real time, using mature network VPN technology.
Steel poles are commonly used to carry several types of electric power lines, distribution lines and lighting system. Distribution lines carry power from local substations to customers. They generally carry voltages from 4.6 to 33kV for distances up to 30 miles, and include transformers to step the voltage down from the primary voltage to the lower secondary voltage used by the customer. A service drop carries this lower voltage to the customer's premises.
