[Abstract]:Intelligent Transportation system (its) is a real-time, accurate and efficient integrated transportation management system, which combines advanced information technology, wireless communication technology, sensor technology and computer technology. As an important part of intelligent transportation system, embedded vehicle monitoring system realizes real-time communication and data interaction between mobile vehicle and monitoring center. The embedded vehicle GPS monitoring system studied in this paper makes full use of the advanced technical achievements such as GPS satellite positioning, GSM/GPRS wireless communication and embedded system. The vehicle terminal based on ARM9 processor can receive the GPS positioning information in real time, and interact with the monitoring center through wireless network. The traffic monitoring center can locate, track and monitor the mobile vehicle. The whole system consists of three parts, including monitoring center, wireless communication network and vehicle terminal system. The main contents of this paper are as follows: firstly, according to the requirement of system function and the working principle of GPS and GSM/GPRS, the overall architecture of the system is designed. Based on the selection of hardware platform and main function modules, the embedded Linux system is transplanted. According to the characteristics of the hardware platform, the corresponding device driver is developed to realize the docking between the hardware platform and the software system. Secondly, the upper application software system is designed to realize the wireless monitoring of the vehicle terminal. For the GPS data processing, the network link and data transmission of GPRS complete the data interaction between the central system and the terminal system, and add the connection between the terminal host and the ad machine of the special hardware device to realize the media playing function. Finally, a large number of module unit tests and whole machine integration tests are designed to ensure the stability and reliability of embedded terminal system.
