摘　　要：本文详细的从硬件与软件两方面介绍了监控市电闯入系统的设计思路与设计过程。该系统是以MSP430F449为核心,包括附叶式传感器,信号处理电路,液晶模块以及键盘模快以及报警设施。文章最后还给出了所设计的样机的仿真结果以及实际的结果。实践证明,它能够非常准确的判断市电是否闯入以及市电范围,此产品将在电信部门有很大的作用空间。This paper particularly discusses the designing ideas and courses of a system that can detect whether there is voltage or not, including hardware and software design. The core of the system is MSP430F449, including peculiar sensors,signal process circuits, LCD modules,key modules and some alarms. This paper ends with some simulation result and the actual result of the sample device we have made. Practice proves that it can well and truly judge whether there is voltage or not and tell the range of the voltage. This manufacture will have great influence on the telecom department.
