说明：  STC89S52单片机设计一款智能充电器的控制系统，通过对电压传感器和电流传感器的检测，当检测充电电压和电流大设置值时，自动断开充电电路。本设计由软件和硬件两部分组成，硬件设计对单片机最小系统、电压电流采集电路、充电控制电路、按键电路、液晶显示电路、报警电路等进行设计，使控制器具备电压、电流检测，系统参数显示，自动断电控制等功能；软件设计方面对控制器的软件驱动程序进行设计。并利用Protues软件进行可行性仿真，对软件和硬件设计进行验证(425/5000 STC89S52 mcu design a smart charger control system, through the voltage sensor and current sensor detection, when the detection charging voltage and current settings, automatically open the charging circuit. This design is composed of two parts: software and hardware. The hardware design designs the minimum system, voltage and current collection circuit, charging control circuit, key-press circuit, liquid crystal display circuit, alarm circuit, etc. , the controller has the functions of voltage and current detection, system parameter display, automatic power-off control and so on. The feasibility simulation is carried out by using Protues software to verify the design of software and hardware)
