Inspection And Monitoring Technology For Intelligent Bus Based On Beidou(Compass)/GPS Navigation Satellite System

Vehicle electronic device is very important function component. Function of various electronicdevices will tend to amalgamation, so multi-function integrated information terminal (IIT) is the developdirection of vehicle electronic device. Integration technology of multi-function IIT will be studied in thispart, consisting of vehicle intelligentized monitoring&control method and electronic device integrationmethod.Firstly, the function model of Bus information terminal is presented. Based on the application actualityof vehicle electronic device, an architecture of automobile intelligent integration control system (AIICS) isproposed. Bus IIT is a sub-system of AIICS. And bus IIT also includes two main modules, vehicleintelligentized monitoring&control system (VIMCS) and vehicle electronic device integration system(VEDIS).Secondly, the key technology to develop vehicle intelligentized monitoring&control system isdiscussed. Based on the function structure of VIMCS, methods to implement some modules such ascommunication protocol (XMQ J1939), vehicle running parameter monitoring, device monitoring andcontrol, default detecting and processing and etc., are detailed.Thirdly, the method to implement the function of vehicle position via Beidou/GPS technology ispresented. We discussed the choice of the Beidou/GPS module and the software design, the goal of vehicleposition is achieved.Then, the method to implement the function of wireless communication via GPRS technology ispresented. Its function module definition and software integration model are given. Thus, the goal ofmonitor and control is achieved.
