地震监测系统的电磁信号的采集设计与实现

Design and Implementation of Electromagnetic Signal Acquisition in Seismic Monitoring System

随着环境的改变,多分量地震监测系统AETA对电磁前兆异常信号有了新的监测需求,因此提出了一种新型的电磁信号采集处理方案。新型的电磁信号采集系统包括信号的实时采集和信号调理两个部分。为了使系统更加安全、可靠且具有便利性,进一步减少维护设备的成本,设计了一种可以自动更新的软件系统——STM32F407,有效提高了监测系统自身的运维效率。一系列的测试证明,信号调理电路符合电磁信号的设计需求,能够快速采集和传输数据,系统的各项运行功能均正常。

Multi component seismic detection system AETA is composed of electromagnetic sensor probe,detection data cloud platform,geoacoustic sensor probe data processing terminal and data analysis system.In order to make the system more secure,reliable and convenient,and further reduce the cost of maintenance equipment,a software system stm32f407 which can be automatically updated is designed,which improves the operation and maintenance efficiency of the detection system itself.After a series of tests,the signal conditioning circuit meets the design requirements of electromagnetic signal,can quickly collect and transmit data,and the operation functions of the system are normal.
