基于ADuC485的多路电池状态监控系统的设计

Design of Status Monitoring System for Multi-channel Battery Based on ADuC485

为了实时监测多路电池的运行状态,设计了多路电池状态监控系统;系统采用ADu C485单片机作为控制芯片,从电池组的温度、电压以及电流三分面分析监控电池组的运行状态。电流采集系统选用分流器,能够将电流转换成电压,方便采集电流;电压采集系统设计的隔离模块电路,将大电压转换成符合单片机运行状态的小电压;温度采集系统选用温度传感器DS18B20;设计了基于多路开关CD4051的多通道切换模块提高了系统测量准确性和抗干扰能力。基于Delphi软件的监控程序,实时记录采集到的参数,并以折线图的形式显示出来,使多路电池状态监控更加直观、迅速、可靠。

The system is designed to real-time monitor the multi-channel battery＇ running status.Selecting ADu C485 SCM as its control chip and collecting voltage,current, temperature to analyze the multi-channel battery＇ running status.Current collection system used shunt,converting current to voltage and collecting current convenient.This paper designed isolation module circuit for the voltage collection system,converting the large voltage to a small voltage can be receiving by SCM.Temperature collection system used sensor DS18B20.The system measurement accuracy and anti-jamming capability are improved by designing multi-channel switching module based on CD4051.
