Tram Monitoring System Based On Java And GIS Technology

With advances in rail technology and fast transport to the city, the pursuit of green travel modes, with environmentally friendly, modern streetcar carrying capacity, stability and intelligence level of convenience advantages of gradually replacing the traditional trams in the rise in major cities, as a new track traffic patterns, modern trams have tram dispatch command system, intelligent passenger tracking system and signal system, intelligent automatic sensor module. For each of the above intelligent modules can effectively stabilize the operation, but also to give passengers a more comfortable ride safe human experience, we need to provide high-precision modern streetcar system, stable and reliable real-time location information Train.Train monitoring system is an important tram intelligent transportation systems link, the key is to accurately grasp the train's current location and status information, in order to better achieve this goal, the paper attempts to combine Java programming software system, SQLServer database technology Modem communication technology train positioning technology, global positioning system, geographic information systemsto be integrated to achieve, and ultimately makes the monitors real-time monitoring of vehicle road status, greatly improve transport efficiency, to ensure road safety.Contents of this paper focuses on how to quickly and accurately in real-time monitoring of the train, and monitor the results are displayed in PC terminal, the entire process to achieve the integration of four structures:(1) Column prison system location information GPS/Compass FRID transponder system obtained using the appropriate algorithm to be amended;(2) Car hardware by Zigbee module to pass information to the column monitoring platform, related to the TCP/IP communications model and serial communication modes specific research and development;(3) Access to the switch machine, signal, whether occupied Track information and other information, and train information, switch machines, signals and other status information for the incoming train monitoring systems and accurate display systems, to ensure communication on the state of the downstream equipment good and stable.(4) column monitoring platform will display complete and accurate information, the system uses Java object-oriented programming concepts, and multi-thread edit mode technology, the three-tier support, allows the system to have better portability, plus parts in different fields on a common method for libraries and smooth without coupling interfaces allow platform used in other transportation industries also simple and convenient.
