The Applied Research About Information Exchange In The Traffic Signal Control System Based On XML And Message Oriented Middleware

The traffic problem is increasingly serious in major cities in the country, and traffic signal control system plays an important role in ensuring the smooth flow of traffic, security and order, but each signal in the traffic signal control system lacks unified communication standards and the degree of information sharing is low, this is not conducive to the long-term development of the traffic signal control system. So this paper puts forward the unified information exchange platform based on XML and message oriented middleware, has realized the information sharing and interaction between the traffic signal control system and each signal.Firstly, based on the analysis of XML and message oriented middleware, further study of information exchange model; secondly, put forward the information exchange standard of traffic signal control system after the demand analysis of information exchange, which laid a foundation for scalability and versatility; thirdly, combined with the advantages of XML technology in data communication, put forward the traffic signal control system protocol TelesemeML(Teleseme Markup Language) based on XML, to solve the communication standard problems between traffic signal control system and the traffic signal machines; finally, to system model and analy and design information exchange in traffic signal control system with UML, set up the information exchange platform in traffic signal control system based on XML and message oriented middleware, and implement a prototype system based on TelesemeML.This paper uses signals as the system control terminal to do the experiment, the experimental results show: the information exchange platform can complete information interaction of bidirectional four channels accurately in realtime between traffic signal control system and the traffic signal machines.The information exchange model based on XML and message oriented middleware has been successfully applied to the traffic signal control system, TelesemeML based on XML provides a unified communication standard between traffic signal control system and the traffic signal machines, the information exchange platform based on message oriented middleware solves problems about information sharing, which contributes to the long-term development of the domestic traffic signal control system, and has high reference value.
