具有区域识别功能计价器车载定位模块研制

Development of orientation module with district-identification function for taximeter device

采用 GPS 技术研制具有区域识别功能出租车计价器中的关键部件——定位模块,编制了相应的运行软件,并进行了调试和试运行试验;对区域识别算法进行了研究,提出了区域识别的算法——弧长法;为了保证通信的可靠性和工作的稳定性,从软、硬件两个方面采取了抗干扰措施。依据交通需求管理理论,能够有效地解决交通拥挤问题。

This essay adopts GPS technology to make the key component in taximeter - orientation module, compiles corresponding software, and makes adjustment and experiment. Also it has done a profound research in district-identification arithmetic, which is radian arithmetic. We adopt anti-interference measures in both hardware and software to ensure communication reliability and working stability. According to Transportation Demand Management (TDM) theory, it can effectively solve the traffic jam problem.
