摘要:
基于多分量地震监测系统 AETA 对电磁前兆异常信号的监测需求，提出了一种电磁信号的采集系统方案。系统包括信号调理和信号实时采集两部分。在信号调理部分，通过对模拟信号进行放大、滤波等处理输出高灵敏度的原始信号。在信号采集部分，为了实时采集和传输所有频段的电磁信号的原始数据，采用了高速、高精度的模数转换器，选择了支持百兆数据传输的 TCP/IP 网络传输协议。同时为了减少设备维护成本，提高系统的便利性、安全性和可靠性，基于 STM32F407 设计了软件系统的自动更新机制，提高了系统的运维效率。测试结果表明，信号调理电路输出电磁信号符合设计需求，采集电路实现了快速采集和传输，系统更新功能运行正常。
Abstract:
Based on the monitoring requirements of multi－component seismic monitoring system named AETA，we propose an electromagnetic signal acquisition system which is comprised of signal conditioning and real－time acquisition．In the signal conditioning，the analog signal is converted into original signal with high sensitivity through its amplification，filtering and other processing．In the signal acquisition，in order to collect and transmit the raw data of the electromagnetic signals in all bands in real time，a high－speed，high－precision analog－to－
digital converter is used，and a TCP/IP network transmission protocol supporting 100M data transmission is selected．At the same time，in order to reduce the cost of the equipment maintenance and improve the convenience，safety and reliability of the system，the automatic updating mechanism for the software system is designed based on STM32F407，which improves its operation and maintenance efficiency．The test shows that the signal conditioning circuit output meets the design requirements，and the acquisition circuit achieves the goal of rapid acquisition and transmission．The updating function of the system works normally．
