Design And Implementation Of A Distributed Comprehensive Management System For Earthquake Precursor Stations

Earthquake is one of the natural disasters which have a great impact on human society.For urban and rural areas,the damage caused by earthquakes is irreversible and even can be devastating.At present,many countries in the world have carried out a variety of studies on the earthquake,and have obtained a huge amount of data.In order to make more rational use of many instrument and equipment and make the measured seismic data be successfully concluded and applied,the researchers also developed the corresponding management system and put it into use.However,with the development of science and the progress of observation technology,the characteristics of the traditional seismic observation management system are difficult to meet the requirements of the modern earthquake precursor station management.The main problems are as follows:(1)the lack of effective real-time monitoring system for seismic stations,instruments and data,affecting the work efficiency of the station.(2)the rapid expansion of the amount of observation data makes the workload of the processing and computing systems increasing.The current seismic station management system urgently needs to update the configuration mode,strengthen the function and expand the capacity.The best solution is to integrate distributed system technology into system design.(3)the information and files of earthquake precursor stations need corresponding management functions to adapt to them.(4)At present,there is no B/S structure earthquake prediction software that can make the station staff used for earthquake prediction,which also affects the further efficient use of seismic precursor observation data.In response to the above-mentioned problems,a set of distributed seismic precursory station comprehensive management system software was developed.The work mainly includes:(1)Conducted in-depth investigation and research on the hazards of earthquake,the current situation of research and the development and use of the information management system of seismic stations at home and abroad.Aiming at the demand of the actual work,it tease out the content of the work for seismic precursor observation stations and process.Using the UML modeling language for the system functional modules,integrating the earthquake precursor station management information data,instrument,analysis of precursors,and instant messaging,papers design and implement the operation of the earthquake precursor station integrated management system.Firstly,users at all levels can master the operation status and working conditions of the station through the system,and communicate and interact effectively.Secondly,the system can monitor the equipment and data of the station in real time,so that the staff can find out the malfunction of the equipment and abnormal data in real time,then checkand solve the existing problems as soon as possible.In addition,the use function of the system can provide data,which can effectively be presented to the users by means of multi view intuitive and be provided to download.The earthquake prediction module can calculate and analyse the data to determine whether it is earthquake anomalies or not.(2)Through the comparison of the domestic and foreign advanced technology schemes,the related research and introduction of the technologies used are carried out.In combination with the features of this system,the system uses the Java programming language,selects SSM as the development framework,and uses MySQL database for coding and development.Data storage uses the combination of HDFS and MySQL,and uses Redis cache technology to cache the raw data into memory,which significantly improves the speed of data read and write operations.At the same time,the distributed data storage improves the system and data security,further optimizes the server working efficiency and enhances the maintainability of the platform.(3)Implement the expected functions and complete storage according to the design requirements and detailed programming.After the system is set up,the system has been repeatedly deduced and verified,and the system has realized the stable module function,which can meet the actual needs of earthquake monitoring and management.After the completion of the system development,the test was put into use at the Lingyang Seismic Station in Shandong Province,and the operation effect was good.The results show that this system is of great significance for improving the working efficiency of earthquake precursor stations,ensuring the normal operation of the instruments,improving the quality of basic work,and strengthening data application and analysis capabilities.
