| Abstract: | A new kind of vehicle navigation and position terminal system, based on 32- bit ARM, GPS and GSM/GPRS, has been re- searched and designed in this paper. The design processes of power system, communicating interface, video system and data acquisi- tion system are explained in details, and a new method of simulating full- duplex communication interface using two 32- bit timers (with 4 capture and 4 compare channels) and PWM timer of ARM has also developed, and 5 full- duplex communication interfaces have been successfully simulated which satisfied the requirement of Serial Interface. The test indicates that the new vehicle terminal can meet the demands of Navigation and Position. |
