Problems solved by technology

[0002] At present, remote power controllers are generally controlled by Ethernet or wireless public network, the workload of wiring and installation is very large, the security of using wireless public network is also poor, and centralized remote control cannot be realized; especially in the power industry, real-time power data requirements Very high, the transmission of real-time data directly affects the safety and reliability of power supply. At present, every substation in the power industry has installed a special power dispatching data network to transmit real-time power data; due to the large amount of data transmission, it often causes power dispatching The data network equipment crashes and the network channel is interrupted, which often requires personnel to rush to the scene to deal with it, especially in some remote substations where the traffic is very inconvenient. It takes a lot of manpower and man-hours to deal with such accidents, and the efficiency is low, causing a lot of unnecessary waste.
