本文首先对过欠压保护器硬件进行了设计，包括电源电路、采集电路和磁保持单线圈继电器驱动电路。随后用IAR visualSTATE状态机软件对整个系统软件进行了设计，编写了输入输出相关事件和动作的API接口函数代码。IAR visualSTATE可以自行产生代码，ROM、RAM消耗量小，非常适宜嵌入式应用，开发完成后可以生成相关文档，便于日后软件维护和升级，大大缩小产品上市时间。

In this paper the hardware of overvoltage and undervoltage protector is designed,including power circuit, data acquisition circuit and single coil magnetic holding relay drive circuit. Then the whole system software is de-signed by using the IAR visualSTATE software,and the related events and actionsˊinput and output code of the API interface function are written. IAR visualSTATE can automatically generate code. ROM and RAM consumption is very small,very suitable for embedded application. After the completion of the development,relevant documents can be generated,which facilitate future software maintenance and upgrade,greatly reduce the time to market.
