Based On 3g Goods Dynamic Tracking System Design And Development

This paper represented the conception, application, and problems of goods' dynamic tracing. Then put forward an idea of goods dynamic tracing system applied to logistics distribution which is based on 3G (GPS, GIS, GSM) .This paper discussed the practicability, key technique and trend of development of 3G based on its application principle. It put forward utilize the receiver installed in vehicle as collector of locator information, GSM short message as transmission method of locator information, GIS as expression of locator information to implement the major function of goods dynamic tracing system. Based on this, this paper established the system's physics framing and logic framing, and decomposed the system to some modules to implement its integrated function, and put forward every module's key technology and the way to settle it.In the system's software-procedure, this paper use the OLE technique to realize data sharing between VB6.0 and MapInfo, foreground process VB coded program to implement system module's function , background call MapInfo processor to manage electronic map and execute vehicle location in the electronic map. At the same time, this paper put an idea that binds vehicle data and goods data to format the database of vehicle and goods in the process of distributing, this idea can format mutual inquiry and location between vehicle and goods.After the test to the software, its modules can basically satisfy the requirements to vehicle and goods dynamic follow system. At the same time this paper approves that the idea of vehicle and goods dynamic tracing system which based on 3G applied to logistics distribution has stronger practicability and promotion for advance the future logistics distribution level of our country.
