Design And Development Of Seismic Exploration Observation System For Cable-Free Self-Positioning Seismographs

The purpose of seismic exploration is to obtain effective geological information.When exploration is performed in different regions,exploration operations are performed using different observation arrangements,which can effectively achieve the purpose of exploration and acquisition,and acquisition.In the face of more complex large-scale seismic exploration missions with observing and arranging data,the design and management of the observing system is particularly important.Firstly,the article introduces the current status of seismic exploration systems at home and abroad.By comparing the functions of the observation system,the problem of the management of the observing system that is missing in the cableless selfpositioning seismic exploration system is analyzed.In the past,when using cableless self-positioning seismographs for exploration operations,the management program mainly used WIFI,3G,BeiDou satellites and other connections,to monitor the status of seismograph equipment.However,there is no systematic management of the arrangement of cableless self-locating seismographs in the observation system.In this paper,combining with the characteristics of the self-positioning seismograph equipment and the practical requirements of field construction,a cableless self-positioning seismograph observation system was designed and developed.The main contents of the system design are as follows:1)Arrangement management system design.The system function is mainly based on the observation and arrangement of data management and records.It is used to solve the problem of arrangement and management of the observation system in the construction site.The system uses user-defined and file-importing methods to obtain the arrangement data.The system parses the obtained data and obtains various acquisition parameters and position information of the shot inspection points,such as line number,station number,and physical coordinates.Arranging the arrangement data recorded by the management system,in the later seismic data processing process,the arrangement information can be automatically written into the header information of the seismic data file,and the data processing efficiency can be significantly improved.The arrangement management system has designed the function of graphically displaying the positions of the shot inspection points.Based on the physical coordinate information of the location points,a block diagram of the shot inspection points is displayed in the system interface,which helps construction personnel to conduct overall management of the arrangement of the shot inspection points.According to the corresponding relationship between the shot inspection points established by the shot table,on-site control of the construction progress can be performed.2)Design of on-site monitoring system for field monitoring and management of cableless self-positioning seismograph during construction,including: arrangement of collection stations,noise monitoring and status management.The collection station arrangement function is for the management of the collection station arrangement,and it reflects the actual arrangement of the collection station on the survey line.According to the arrangement information of the class report data record,the display management is also performed in the interface module in a graphical manner.The noise monitoring system is used to monitor the noise situation at the construction site and help the construction personnel to select the right timing for blasting.The noise value is represented by the average value of the noise data over a period of time,and the noise value is visualized in the form of a noise bar refreshed at a certain frequency.The status management function is the management and control of the status of the collection station.The system acquires the status information of the collection station in the form of sending and receiving instructions,and displays the status information in the program interface.It helps the construction workers to grasp the status information of the collection station at any time and controls the collection station..In laboratory tests and field applications,this system can provide the functions of arrangement management and on-site monitoring,effectively remedy the problems of past monitoring procedures for the overall management of observing systems,can meet the on-site management requirements of construction acquisition tasks,and improve construction efficiency.
