基于无线网络的无缆地震仪远程监控系统

摘要

Aiming at the problems in acquisition process of seismic data,such as staff members are unable to monitor and control instruments remotely,the remote monitoring system for cable-less seismograph based on wireless network technology is designed and implemented. The system consists of two parts, the cable-less seismograph and the main control center. The cable-less seismograph is divided into two types in accordance with the communication modes, one is with normal node,and another one is with gateway node. The normal node is connected to gateway node via WiFi, the gateway node is connected to Internet via cellular network for setting up TCP connection with main control center. The real time monitoring of the operation status of the cable-less seismograph and the detection of the quality of seismograph data are conducted in main control center. The tests show that the system possesses excellent stability and real time performance;it can be used in seismic data acquisition.%针对地震数据采集过程中工作人员无法远程监测和控制仪器的问题，设计并实现了一种基于无线网络技术的无缆地震仪远程监控系统。该系统由无缆地震仪和主控中心两部分组成。无缆地震仪按照通信方式被分为普通节点和网关节点两种。普通节点通过WiFi连接到网关节点；网关节点通过蜂窝网络连入互联网，与主控中心建立TCP连接，主控中心完成对无缆地震仪工作状态的实时监控和地震数据质量的监测。经测试，基于无线网络的无缆地震仪远程监控系统具有良好的稳定性与实时性，能够在地震数据采集工作中使用。
