The Realization And Design Of The Seismic Network Real-time Monitoring System

With the rapid development of Internet technology,it is srongly demanded using networks to collect and distribute the sismic data,and report the sismic parameter rapidly.In this way we can reduce intermediate step and make the rapid report efficiently and exactly,so we design and program this so-called Seismic Networks Real-time Monitoring and Rapid Report System to make sure the rapid reprot result is scientific,logicla and exact.This system is used to collect and analyse the seismic data and locate the earthquake in one system to make sure monitoring and rapid report is Real-time and exactly.however, we not only care of collect the data simply,but also pay attention to the data's qulity and the rapid report's timely and efficiently,because the policy and decision is based on the fact,and the key factor is the data.This software is developed in this purpose.This article's work and mainly contribution as follows:According to the relevant theories of the modern software development, investigated the method of the requirements analysis.While receiving the requirements analysis, we obtained the consumer's requirement by the colloquium, the manufacture details, the impersonation role etc. Researched to the existing earthquake calling system, asked several national well-known expert in seismology to do the requirements analysis, and formed the requirements analysis report of the project on the foundation.We used prototype method to receive the validation to the requirement of the consumer, and inspire the further requirement with this.Using the relevant method of the database design, set up the information model of the system.In the system's database design procedure, combined the actual work's demand, according to four steps of database design, combined the 3NF design principle to receive the construction of the database, and constructed a great deal of view on the basic data table, reduced the redundancy of the data consumedly, improved the run-time efficiency of the database, strengthened the safeness of the data.Using of modern tool, completed the design of the system's structure. After comprehending the user requirements well, we designed to the overall system, put forward the structure of the system, lay the foundation for the coding of the system. Adopting various technique meanses, carried out various function of the system.In system's carring out of procedure, according to the process of the work and the flow chart that was gotten by the user requirements analysis and the full consideration circumstance of various possible presence, implemented the sysytem. Adopted to argument of body technique, preventing-chain technique, investigating the meanses before data storeing, verification code technique etc,these raise the safeness of the system. Stationing angle in consumer, carried out the batch data records to go into, modified and deleted etc. The user can carry out the operation of the database to input directly SQL statement at the browser, this can satisfy each kind of operation of consumer.Adopting various test techniques, perfected system.In the procedure of systems test, we carried out the test of the function, performance etc. In testing, we put forward the homologous improvement opinion to existent problem. This provided the good reference with improvement for the next mend of the system.
