The Design And Realization Of Real-Time Monitoring System Software For Rock And Soil Microseismic

In recent years,with the rapid development of industrialization,energy industry,tunnel excavation and so on are developing rapidly.However,in the process of energy mining and tunnel excavation,due to the structure of the rock and the influence of various factors,safety accidents such as rockburst and landslide may occur.The study of geotechnical field shows that the microseismic events occur before the occurrence of mine rock collapse.By detecting and analyzing the waves of microseismic events,it can reach the purpose of early warning.Therefore,in the process of mine minning,tunnel excavation and other underground construction,designing microseismic monitoring system which can be used for real-time microseismic waves monitoring,analyzing,early warning will be significant to reduce the occurrence of disasters and protect people's lives,in the national economy and social development.This paper mainly discusses the design and implementation of a real-time monitoring system software for rock and soil microseismic.In the first,geotechnical microseismic monitoring system is briefly introduced.At the same time,aiming at the shortcomings of the traditional microseismic monitoring system,this paper clearly put forward the needs for the real-time microseismic monitoring system wanted to be designed and realized for this time.Then,through the requirement analysis,after comparing the key parts of the system which have more than one alternative,including the network transmission protocol,data storage and database,the method of microseismic source location and P wave arrival,combined with the actual application scenario,the scheme has been designed.Then,with the division of the function module of the system software and elaboration of the function,as well as the design of the database and the design of real-time of the system software,the design of the whole system software has been completed.After that,this paper discusses the implementation process of each functional modules,and gives the corresponding implementation flow chart.At the end of this paper,the functional modules of the whole software are tested,besides,the performance of this system software is tested for its accuracy of microseism locating and the instantaneity.Finally,the corresponding test platform and environment,test results and analysis are given.The experimental results show that all the functional modules including data receiving and automatic processing,microseismic event query,historical data query,manual processing,database operation,drawing and parameter configuration modules meet the design requirements.In the aspect of performance test,this paper has tested its instantaneity,the accuracy of the hypocentral location of this system software.The results show that the real-time performance of the system is good,and the design requirement is reached.At the same time,the average error of the source localization of Newton downhill method is below 10 m,meeting the performance requirements.
