Abstract:  Aiming at the current development of logistics and transportation, a design method of logistics dynamic traceability system based on Beidou satellite navigation system is proposed. Combined with embedded technology, wireless communication technology and sensor technology, designed a logistics dynamic traceability system, so that a variety of information in the process of transport can be realtime monitoring. The system has many functions, such as obtaining location information, showing trajectory of tractor and path planning. The actual test shows that the system is running smoothly, with high precision and high stability.
