一种基于AVR单片机的直流电源监控系统

A Sort of Direct Current Power Supervise Control System Based on AVR Chip Computer

介绍一种基于AVR单片机(Atmega128)实现的直流电源监控系统的设计方案及其软、硬件设计思路。该监控系统能检测直流电源系统的各种实时运行数据及状态,自动监测各种故障并发出声光报警,实现蓄电池的智能管理;通过RS232或RS485与上位机通信,实现遥信、遥测、遥控和遥调等功能,能较好地满足无人值守变电站及配网自动化的需要。

The design means for the DC power supervise control system based on AVR chip computer and the logic of hardware and software design are introduced. This system can detect all real time operation data and state of DC power supply system, and supervise the failure of the system and send off acousto|optic alarm, so as to achieve the intelligence management for storage battery. The communication with the local control computer is conducted though RS232 or RS485, which implements the operation of distance communication, remote metering, distance control and distance regulating to meet the requirement of transformer substation and power distribution automation without people on duty.
