基于LoRa技术的节点地震采集单元数据远传系统设计

Design of a remote data transmission system for seismic node acquisition units based on LoRa technology

目前,地震数据采集节点多数采用了分布式自主采集模式,使用中缺乏有效的现场质量监测手段。当前普遍采用的人工巡检、数据回收等工作耗费了大量的人工和较长的施工时间,采集数据的质量和施工效率难以得到保证。根据现场施工需求,基于主流LoRa无线通信技术以及物联网软件架构的发展,在原有地震采集节点的基础上增加LoRa无线采集模块,同时通过网关的自组网方式,并搭配物联网服务器软件,进行节点状态参数的远距离传输,实现了节点采集中的质量监控。

Presently,most seismic nodes operate as distributed autonomous acquisition stations that lack a coordinated on-site quality monitoring.Manual inspection and data recovery are costly and time-consuming.Therefore,the quality and efficiency of operations are difficult to guarantee.According to the requirements of the work site,exploiting the development of an internet-of-things(IOT)software architecture and the mainstream LoRa wireless communication technology,a LoRa wireless acquisition module was added to the existing nodes.Using a gateway’s ad-hoc network mode and IOT server software,remote data transmission and quality control was realized.
