摘要
本文设计了一种能够检测锂电池电压和温度的系统,能够把测量结果通过串口上报,并且可以根据结果进行声光报警指示和风扇控制散热,它主要由AT89C51单片机控制模块,A/D转换模块,DS18B20温度采集模块,串口通信模块和LCD1602液晶显示模块等组成,解决了锂电池在使用过程中的安全问题。
A lithium battery voltage and temperature detection system was designed by the author, which consists of AT89C51 MCU module, A/D converter module, DS18B20 digital thermometer module, serial port communication mod-ule and LCD1602 display module. It can be used to detect the voltage and temperature of lithium battery and resolves the security problem when the battery is working.
