| Abstract: | Based on location technology of GPS/GSM network, the parameters about the user’s movement locus, real speed, locomotion direction and vehicle state of mobile aim are mornitored and controlled, in order to ensure safety of mobile vehicle, schedule management and operation efficiency. The system is composed of mobile vehicle, transfer network and monitor center, where data are transmitted based on GSM sound channels, and exchanged between GPS block and AT89C51 based on RS232 serial communication ports. The paper introduces hardware composition, work principle and software design of mobile vehicle location system. Relative technologies of mobile location are discussed. |
