摘要
讨论了GPS和航位推算系统两种定位技术,给出了基于这两种定位技术的车辆定位系统的硬件构成.介绍了系统重要组成部件:PC104计算机、JupiterGPSOEM接收机、HMR3000电子罗盘以及里程计的主要性能.给出了JupiterGPS接收机、HMR3000电子罗盘、里程计与PC104计算机通信接口电路的设计.实验结果表明,本文所讨论的系统硬件的设计是合理有效的.
Two kinds of position technologies such as GPS and dead reckoning system are discussed, The hardware frame of vehicle position system based on two position technologies is proposed. The different performance of PC104 computer, Jupiter GPS OEM receiver, HMR3000 electronic compass and milemeter is discussed. The communication circuit design between PC104 computer and Jupiter GPS OEM receiver, HMR3000 electronic compass and milemeter is discussed respectively. The experiment results show that the design of hardware system is valid.
