The Design And Exploiture Of A Data Processing System Of Strong Motion Network Center

Earthquake observation (Strong Motion Instrumentation) is the exact meaning of strong vibration observation, it is to use equipment to observe the strong earthquake ground motion and in the process of engineering structures under earthquake response, and proceed to near-field earthquake engineering and seismology on the basis of information provided. Earthquake quick report network security building in Beijing is part of precautionary measures, seismic disaster reduction is also part of Beijing, Beijing's security and prosperity has a special significance.Eclipse RCP can give the exploiter to found may expand the client side application procedure the ability, also gave the general Java exploiter to provide the compilation to have the characteristic bright local impression and the use experience rich client side code ability.According to the java language characteristic, develops in the platform in Eclipse RCP to carry on the software the design and the development.Causes the JAVA code with JUnit to become more vigorous and healthier, more reliable.Socket is the application layer and the TCP/IP agreement race correspondence middle software abstract level, it is group of connections.The system selects the Socket communication method and macroseism each sub-Taiwan carries on the data communication, the data packet form which the stature Taiwan use defines to the system transmission data.The system is responsible for the data which receives and the buffer receives. The CD-1.1 protocol is the earthquake system specialized transmission data agreement, not only it moves in the reliable agreement, moreover may move in the UDP agreement or other agreements.The support to many place transmission and the receive, may use many IP.This article according to the CD-1.1 protocol the characteristic as well as the Socket communication way, has realized many Taiwan station transmission data receive.Has solved before must 24 hour real-time transmission data question.Not only now may the discontinual transmission, moreover may carry on between each station in the data transmission process the parameter control, has realized the intelligent control communication.Verifies the frame with Crc64 the integrity and the accuracy, reduces the method with Steim1 to reduce the data quantity, guarantees the data transmission with the DSS digital signature the security and the reliability. Carries on the expansion using Eclipse based on the plug-in unit the thought, built one to use in the profile demonstration the application procedure, like this realized the receive stature Taiwan data profile to demonstrate, the earthquake profile demonstrated divided into three components: Vertical component, north and south component and thing component.And may to demonstrate as necessary the profile the reproduce by pantograph and the position carry on the adjustment.
