Design of Geophysical Information Collection Terminal Based on “Internet Plus”

随着物联网技术的不断发展,以及“互联网+”时代的到来,构建一种低成本密集分布式地震观测系统成为了可能。本文设计了一种基于“互联网+”的地球物理信息采集终端,用于定时采集地震孕育过程中的地球重力加速度、地磁场、温湿度、大气压及低频电磁波等地球物理信息,采用以太网或GPRS通信方式将数据上传至地震监控中心服务器群,可为地震的大数据分析预测工作提供大量的实时数据支持。文中简单介绍了低成本密集分布式地震观测系统的结构功能,着重分析了系统采集终端的软硬件设计及数据预处理。该终端结构简单、功耗低、数据传输可靠,可用于大范围分布式布设。

With the continuous development of Internet of Things technology and the arrival of“Internet plus”era,it is possible to construct a low cost dense distributed seismic observation system.In this paper,a geophysical information collection terminal based on“Internet plus”is designed to collect geophysical information such as Earth’s gravity acceleration,geomagnetic field,temperature and humidity,atmospheric pressure and low frequency electromagnetic waves during the time of earth-quakes.Using Ethernet or GPRS,the communication mode uploads the data to the earthquake monitoring center server group,which can provide a lot of real-time data support for the large data analysis and forecasting work of the earthquake.In this paper,the structure and function of low-cost dense distributed seismic observation system are briefly introduced,and the hardware and software design and data preprocessing of the system acquisition terminal are analyzed emphatically.The terminal structure is simple,low power consumption,reliable data transmission,and can be used for large-scale distributed layout.
