便携式磁场异常监测系统设计

DESIGN OF PORTABLE MAGNETIC FIELD MONITORING SYSTEM

本文设计了一种便携式地磁场异常监测系统,介绍了监测系统的硬件设计过程,包括串口电路、时钟电路、报警电路、液晶电路等,以及监测系统的软件设计流程。该系统电路简单,成本低廉,可分布于各监测点对地磁场进行监测,通过串口将ROM中的数据发送给PC,在基于地磁场的地震监测与预报领域,有着广泛的应用前景。

A portable magnetic field monitoring system is designed. The design of hardware includes serial interface circuit, clock circuit, alarm circuit, liquid crystal circuit and so on. The design cycle of software is introduced, too. The system has the advantage of simple circuit and low cost. It can monitor magnetic field on different measuring point at the same time. The monitoring data can be transferred to the compute by serial interface. The system has a wide application foreground in the domain of earthquake monitoring and prediction.
