With the rapid increase of motor vehicle ownership in China and the construction of the national road network , the increasingly frequent exchanges between the intercity , driven by short-term interests and long-distance passenger transport market widespread overcrowding, speeding , fatigue driving , thus causing heavy catastrophic accidents occur frequently, people's lives and property safety has become a major threat . This article the functional requirements for the long-distance bus monitor , the design of the remote monitoring system based on GPS / RFID / GPRS / GIS . The system is divided into two parts of the vehicle terminal and monitoring center to achieve , in-car terminal using ATmega2560 as the main controller , combined with GPS, RFID and multi- sensor detection to achieve vehicle location and overcrowding , speeding, fatigue driving judgment , vehicle operating status information and in - car image information in the data frame format agreed uploaded via GPRS data channel to the monitoring center and the GSM short message as an alternate means of achieving the key parameters of vehicle operation uploading . Monitoring center software design using Visual Basic as a foreground Access as a back-end database , using the Winsock information received via the TCP / IP protocol to upload (or use MSComm receiving information via short message uploaded ) , and information parsing , access, display; using MapX secondary development of GIS platform , complete the basic operation of the map , binding Access data source , real-time dynamic display of vehicle location or playback historical trajectory to achieve real-time monitoring of online vehicle monitoring center by the TCP / IP protocol , or short message issued query run state instruction scheduling instruction , service / warning information to achieve real - time vehicle management , scheduling and services . In addition, if the vehicle suffered a robbery or an accident to the monitoring center can upload alarm information to organize rescue and improve the ability to respond to emergencies in a timely manner by monitoring center . Been tested , the system to achieve real - time information exchange between the mobile vehicle terminal and monitoring center , the system is able to coach with monitoring terminal to achieve the weather dynamic real-time monitoring , scheduling and management , improve the operational level and the scheduling of a long-distance bus safety management efficiency .
