Feeder terminal for intelligent power distribution network

Abstract

The invention relates to the field of intelligent equipment for power transmission and distribution. The invention provides a feeder terminal for an intelligent power distribution network. The feeder terminal comprises a CPU (central processing unit) control module, an electricity quantity acquisition module, a switching value input / output module, a wireless communication module, a data storage module and a power supply module, wherein the electricity quantity acquisition module, the switching value input / output module, the wireless communication module, the data storage module and the power supply module are connected with a CPU terminal; the wireless communication module is connected with the power supply module; the CPU terminal is an ARM processor. The feeder terminal based on solar energy and the ARM processor and provided by the invention has the advantages that the functions of acquiring, processing and storing electricity quantity in real time, monitoring and controlling switch on-off state, monitoring power supply voltage, performing wireless communication and the like are realized; by adoption of a wireless network data transmission technology, the trouble from cables is prevented, the data transmission cost is lowered, and the flexibility and anti-interference performance of the equipment are improved; the solar energy is adopted for supplying power, so that the situation that a monitoring terminal of the feeder terminal cannot work due to line fault is prevented.
