Design Of Train Monitoring System Based On GPS/GIS

In the process of train operation, how to accurately grasp a moving target current location information and real-time display in people's eyes has become one of hot issues. Therefore, GPS / GIS intelligent traffic monitoring system has been created. It combines a global positioning system technology, Geographic Information Systems technology and modern communications technology to achieve a real-time location monitoring of trains. This system makes people, vehicles and road work closely with staff to deal with increased ability to train fault.This paper has been designed a monitoring system for emergency vehicles based on GPS / GIS technology. In several wireless data transmission we select the GPRS General Packet Radio as a data communication. We have installed GPS modules and WACOME Q2403A GPRS module on the train terminal to receive and send data. Monitoring Center is responsible for communication through the GPRS network of GPS positioning data processing, combined with VB and MapX component technology to achieve a real-time monitoring, information inquiries, such as the history of the main functions of the track playback monitoring interface.The system uses GPRS data transmission network as a platform for enhanced real-time data transmission, and increased transmission flows and improve the data transfer rate and reduce the bit error rate and reduce the communication costs. This network is applicable to the sudden application of the data such as the GPS system. In addition, during designing the electronic map, using the MapInfo's MapX Component Object Model as a secondary development, making the work of relatively simple programming and shorten the development cycle. Monitoring Center of the man-machine interface used in the form of electronic maps, and can do the following operations for the entire interface ,such as enlarge, reduce,roaming and also can control map layers'information .This system is simple and clear, easy to operate,and it has the basic functions of the emergency vehicle location monitoring system.
