Logistics Tracking And Vehicle Detection System Design Based On Embedded Technology

With the continuous improvement of logistics transportation carryings and the rapid development of logistics industry, some issues have followed.Such as the corresponding speed of logistics is slow, the goods in transit is lossserious, logistics vehicle especially the vehicle that loading of dangerous goods occur accidents frequently.For this reason, a system for logistics tracking and vehicle attitude detection based on embedded technology was studied. The system consists of three main parts. They are a logistics company’s data center and a in-car system and a client. The embedded technology is used in the in-car system. The available angle values was acquired through a MPU-6050 moduleand that can collect the information of vehicle attitude and use Calman filter to count the initial angle value. The position information was acquired through SIM908 module.The information between the vehicle platform and data center was transited by GPRS. The data center can not only realize the quer function of vehicle information and cargo information, but also realize the information function between the center and the in-car system.The date center integrate with Baidu map of API and OpenGl technology to display the vehicle’s pposition on map and 3D pose informa-tion.The client use the INTERNET network for the date transfer between data center and the in-car system. The customer can inquiry the transport information on the client system.Through the research and test on the system,the main functions have been realized.The cargo information can be recorded on the in-car system.The goods can be positioned through the positioning for vehicle.The call information and the vehicle attitude information can be received by date center when the vehicle accident.The attitude information can display in 3Dsimulation image mode.
