Research On Digital Logistics Vehicle Main Control Center System Based On RFID And GPS Technology

The digital logistics system is a high integrated information management system based on the traditional logistics, which applies the advanced scientific methods to be available to speed up logistics, to enhance accuracy , to decrease stock reduces, and to reduce cost. This paper will integrate the two technologies of GPS (Global Position System) and RFID (Radio Frequency Identification). It study and develop a digital logistics based on RFID and GPS. The system has some features that are in real-time monitoring of common information for the flow of objects and movement of vehicles, identification of three-dimensional positioning and stronger security features. The digital logistics system includes two parts: the digital logistics vehicle terminal system and the digital logistics vehicle main control center system. At present, in terms of logistics system only based on GPS technology , it is typical of broader application, more security, more intelligent. The paper main study and develop the digital logistics vehicle main control center system based on RFID and GPS technology. The main work of this paper is as follows:Firstly, to the digital logistics main control center system, the paper make a whole design for every module, and definite the functions, relations and assignments of different modules. Our study focuses on wireless data transmission, communication potocols and database structions, the mutual interface of people and computer.Secondly, the software modules and the hardware modules of vechile main control system have been developed and debugged. The specific contents are as follows:(1) In hardware circuit aspects , the paper develop and debug the transceiver board of vehicle main control center system. Using by the transceiver board, the paper can implement to receive the notes of vehicle terminates and to send order information The transceiver board includes GSM(Global System for Mobile Communications) communication module, serial output module, electric power module and MSP430 microprocessor module.(2) In software aspects, as the core of MSP430, it program in order to control GSM module and serial module and achieve to read note from GSM module and to send information by serial port. In addition , the application programs of the PC(Personal Computer) , which include the programs of the mutual interface of people and computer, the programs of decapsulating data packet protocol, the programs of coordinate transformation and the programs of database storing and hanging , can achieve to track the digital logistics terminal and display timely the terminal running routesFinally, the paper has debugged the whole vehicle main control center system. The result of debugging indicate that the system can rapidly and accurately acquire the wireless information from the vehicle terminates , and process and store the data from RFID and GPS. The useful information can display the mutual interface of people and computer. At the same time the mutual interface of people and computer can be exchanged for automotive terminals to the acquisition of RFID and other relevant information to provide a reliable and effective platform for the display...
