Dangerous Goods Vehicles In The Gps / Gprs / Rfid-based Monitoring System

Being the international metropolis,the development of safety is one of the most important content of the economy construction of the city Shanghai,and the important part of the construction of the harmonious society.Shanghai has been the leading one in supervising the transportation of the unsafe goods all the time,howerever,there are some hidden troubles all the same.The main reasons are those:there have been some lack in supervising the vehicle transporting the unsafe goods as the dynamic source of the danger beforehand and dynamic. So,in order to meets the requirement of the Department of the Shanghai safety production,the article brings forward the designing project of supervising the transportation vehicle of the unsafe goods based on the technology of GPS/GPRS/RFID,which provides the realism foundation for supervising the vehicle transportation in Shanghai efficiency.The paper has accomplished the main tasks,as below:<1> The paper discussed some important technology including GPS orientation,GPRS wireless transferring,RFID the system involved,and introduced the development,application,and the theory of them, which settle the foundation for the following chapters.The paper made a short introduction for some main communication technology,such as the GSM communication network,CDMA system,fixed frequency communication,multi-frequency communication,secondary planet communication,and chose the GPRS wireless transferring in this system after comparing the characteristic of these communication mode.<2> In allusion to the requirement of the supervising the Shanghai unsafe vehicle,the paper brings forward the designing project of supervising the transportation vehicle of the unsafe goods based on the technology of GPS/GPRS/RFID,which tailed the vehicle with the GPS orientation,checked the vehicle information with RFID technology,and transferred the vehicle orientation information and unsafe goods information with GPRS wireless transferring mode,and also provides the designing idea and function of each subsystem.<3> The paper demonstrated the designing idea of the tulip which applied in the subsystem of the vehicle supervising,realized both the hardware part and the software part of the tulip,and accomplished transferring the GPS information based on the GPRS,and the software design of the remote server.<4> The wireless transferring of the vehicle information with RFID has been explained,using the RF chip NRF401 to transfer the information,and the chip of MAX232 to make the MCU communicate with the computer. <5> Has tested both the hardware and the software,and also made some experiments and analyses,,done some researches on the fleetness and reliability of each pans.According to the result of the test,the system was practical and useful,which has some use for reference for the safety construction of Shanghai.
