基于GSM的无人值守地震台站远程监控系统

A Remote Monitoring and Control System Based on GSM for Unattended Seismic Stations

摘要:

针对无人值守地震台站特点，通过传感技术和嵌入式技术，采用低功耗、功能强大的单片机微处理器以及稳定、安全、嵌入式的GPRS/GSM模块等设备进行开发，实现无人值守台站的的环境监控以及远程控制。当无人值守站点交流电中断或SDH链路异常时，该监控系统均能第一时间报警并短消息提醒设备维护人员，很好应对人为对台站环境以及地震设备的影响；同时系统也能响应客户端指令完成数采等设备的断电和重启以及设备工作环境的监测，当工作环境监测到火情、盗情及温、湿度出现异常时，系统会向客户端发送报警信息，这对提高无人值守站点的技术系统稳定性与数据产品的稳定、连续性都具有重要意义。

Abstract:

To ensure the reliability, stability, and continuity of seismic monitoring data as well as the normal operation of seismic monitoring instruments at unattended seismic stations, a system is developed in this study using a sensing technology and embedded technology, as well as a powerful microprocessor and stable, safe embedded GPRS/GSM modules and other equipment. Using this system, functions such as environment monitoring and remote controlling can be realized in an unattended station. The unattended station is interrupted by an alternating current or an abnormal synchronous digital hierarchy (SDH) link, and the monitoring system can alarm and remind the maintenance personnel; this benefits both the supervisor in charge of the station environment and the seismic equipment. In addition, the system can also respond to the client instructions, complete an outage and restart of the station instruments, and monitor of the equipment working environment. The system will send an alarm information to the client the instant it detects abnormal cases, such as fire, theft, and change in the temperature and humidity, which is of great significance to improve the stability of the technical system as well as the stability and continuity of the output data.
