The main research work are as follows:1. Hardware design: The hardware design mainly consists of the MSP430147 microcontroller、the GPS module and the GPRS module, the GPS module receive information through the satellite positioning to determine the current latitude and longitude, the GPRS module is responsible for communications with the service stations, to ensure the timely for the current location of the goods, the MSP430147 microcontroller is the control module and the core of data acquisition.2. Software design: The software is designed by C language, according to the Remote Data Acquisition System functions, a design about circuit schematic of microcontroller system is completed, the GPRS module is controlled by the AT command through data line between microcontroller system and GTM900 module , it describes the design of software flow charting, including the GPRS main program, the GPS modular data acquisition system procedures, the RFID modular data acquisition system and the microcontroller data communication program.3. We expand the function of the system add the RFID (Radio Frequency Identification) technology on it. It can identify and register the tag on the cargo, and send the receiving data to host microcontroller through RS-485 to process.4. After debugging, the GPS modular system can receive positioning data, and in a certain period of time through the transmission to the 485 communications system GPRS module, Each time the receiver can transmit completely.更多还原
