电动汽车充电站车载定位系统的研究

Positioning System of Electric Vehicle Charging Station

随着电动汽车的不断普及和发展,其配套设施也受到了越来越多的关注,尤其是充电站的建设已经提到发展日程上来,如何对充电站进行快速准确定位成为驾驶员最为关注的问题之一。针对传统汽车导航仪需要定时升级的弊端,本文设计一种新型的电动汽车充电站车载定位系统,该系统主要由DSP处理器、GPRS收发模块、GPS接收模块等组成。其中,DSP处理器负责数据处理,GPRS收发模块负责接收充电站的地理位置、使用状态等信息,G PS负责电动汽车的定位。系统可以将接收到的充电站位置信息直接嵌入到内置电子地图中,实现对充电站的实时定位和路径规划,克服了传统导航仪需要定期更新电子地图的缺点,从而为用户提供一种低成本、高性能的无线充电站定位方式。

With the development of electric vehicles ,the supporting facilities,especially the charging sta-tions ,have caught more and more attention. How to locate the charging stations quickly and accurately is becoming one of the most important problems for the drivers. In accordance with the disadvantage of tra-ditional navigators to upgrade the electronic map in time,a new type positioning system of electric vehi-cle charging station is proposed. The system is mainly composed of DSP,GPRS transmission module, GPS transmission module. The DSP is used to process the data. The GPRS module is used to receive the geographical position and statement of charging station while the GPS module is used to locate the charging stations and the vehicles. The system can embed the position information into the electronic map and realize the real-time location and path planning,which overcames the disadvantage of naviga-tors. It provided the drivers with a low-cost and high-performance method of charging station position-ing.
