摘要：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。

0引言

人们对石油和天然气日益增加的需求不断推动着资源勘探工作快速发展。作为资源勘探最主要的方式，陆上地震勘探具有作业范围大、采样节点众多、产生海量数据等特点。实际工作中，工作人员需要对几十万个采集设备进行操作(检测、布设、回收)。由于节点数量巨大，用于通信的线缆占地震勘探总装备重量的75%，且对通信线缆的检测、铺设以及回收工作是整个勘探工作量的50%。除此之外，由于通信线缆无法横穿铁路、公路，传统地震勘探设备在该类区域内无法工作[1]。……
