51单片机蓄电池充电保护设计Proteus仿真功能描述如下：本设计由STC89C52单片机电路+LCD1602液晶显示电路+ACS712电流检测电路+分压电路+PCF8591 AD检测设计+继电器电路+DS18B20温度传感器。系统具有过压保护、过流保护和过温保护。即如果蓄电池的电压超过14 V或充电电流高于0.7A或温度高于40℃，则继电器断开,否则继电器闭合。液晶LCD1602实时显示温度、电压和电流。1、tDS18B20检测温湿度；2、tPCF8591检测电压；3、tACS712检测电流4、t将测得的温度和电压、电流显示于LCD1602上，同时显示继电器状态ON OFF；5、t根据温湿度、电压、电流控制继电器开关，保证在过温、过压、过流情况下及时断开电源；6、t电路上的模块使用标号进行连接，看起来像没有连在一起，实际已经连了，不然怎么可能实现上述功能。 <link href="/image.php?url=https://csdnimg.cn/release/download_crawler_static/css/base.min.css"
