With the continuous advancement of the modernization process,today's China has undergone earth-shaking changes,people's living standards and quality have significantly improved,and the pace of industrialization has been continuously accelerated,which has accelerated energy consumption and the supply of energy New challenges have been raised.At the same time,there are constant geological disasters.According to relevant data,China is one of the countries with the highest frequency of geological disasters.In order to solve the above-mentioned increasingly difficult geological problems of resources,energy and geological disasters,the most effective way is to march deep into the earth and understand the geological information of the deep earth.Among the various geophysical exploration methods,seismic detection is one of the most effective methods,and has been widely used in mineral resource exploration,geological information survey and other fields.In the seismic detection method,the detection with the help of natural earthquakes has the advantages of low cost,simple operation,and large depth of detection.It has attracted more and more attention from scientific researchers and applied it to different exploration projects.Natural seismic signals have the characteristics of frequency bandwidth and large focal depth,and require high-precision natural seismic recorders for accurate acquisition and recording.In this regard,China has long relied on imports,which are not only expensive,but also subject to people.Therefore,Jilin University independently developed the GEIBSR-I wideband seismometer,breaking the monopoly situation abroad.However,it is inevitable that during the observation of natural seismic signals,the instrument needs to work in the field for a long time,and the distance between the instruments is large.The monitoring of the instrument state and the recovery of seismic data need to be processed at the monitoring site.A large amount of human,material and financial resources are required,and the working status and recovery data of the instrument cannot be understood in a timely manner.In order to solve the problems of real-time performance and cost of instrument monitoring and data recovery,a wideband seismometer remote data monitoring system based on cloud server is designed in this paper.The system structure is mainly divided into two parts,namely the terminal data acquisition and transmission subsystem and the cloud server data processing subsystem.The terminal data acquisition and transmission subsystem mainly implements the acquisition,preprocessing,and transmission of seismic data.The cloud server data processing subsystem mainly implements receiving,analyzing,and processing of terminal data.Firstly,the hardware circuit was improved based on the original wideband seismometer.Two-level voltage conversion circuit and interface circuit were added to it.The embedded Linux operating system and 4G module dial-up Internet access program were transplanted to form a new terminal.Then,design the cloud server platform software,including server building,network client program design,etc.Finally,tests were performed,and the results showed that the terminal realized dial-up Internet access and uploaded the collected data to the cloud server.The cloud server can receive the data uploaded by the terminal,can process the data,and visually check the various working status of the instrument and remotely recover the data.
