介紹了電力操作電源與智能電池巡檢系統(tǒng)的特點(diǎn),給出了一種基于超低功耗單片機(jī)MSP430 F149針對(duì)中小型變電站自動(dòng)化運(yùn)行的專(zhuān)用設(shè)備的基本設(shè)計(jì)原理及實(shí)現(xiàn)方法,最后給出了詳細(xì)硬件構(gòu)成和軟件實(shí)現(xiàn)。該系統(tǒng)能滿(mǎn)足中小型變電站安全、可靠、自動(dòng)運(yùn)行的要求,并通過(guò)與上位機(jī)的串行通信實(shí)現(xiàn)變電站的遠(yuǎn)程管理和控制。
Abstract:
The characters of the intelligent battery data logging system of the electric operation power are introduced.The basic design principle and the implemented methods of the special equipment which only designed for the middle or small transformer substation based on MSP430F149 are prescribed. Finally, the hardware block diagram and the software flow chart are also given. The function that the system finally needs to realize can basically meet with the middle or small transformer substation’s satisfy, reliably,and automatic running.And it can also realize the transformer substation long-distance management and control by serial communicating with the host computer.
