“两客一危”GPS卫星定位系统车载终端设计

摘要

道路运输车辆卫星定位系统车载终端，是实现全国重点营运车辆联网联控系统统一的重要组成部分。车载终端的设计充分利用JT/T794—2011交通运输行业标准进行设计，采用内置的GPS卫星定位模块获得定位信息，以及利用车辆状态信息采集模块获得车辆运行情况信息，通过GPRS传输模块传输数据，同时具有对车辆监听、通话的功能。实验结果表明，道路运输车辆卫星定位系统车载终端功能良好。具有很好的实用性。%Road transport vehicle satellite positioning system vehicle terminal, is the realization of national key operating vehicle network of joint control system of an important part of the unified. Terminal design make full use of JT/T 794-2011 transportation industry standards for the design, using GPS positioning module to obtain positioning information, and the use of vehicle state information acquisition module for vehicle running condition information, via GPRS transmitting module to transmit data, at the same time on the vehicle monitoring, call the function. The experimental results show that, the road transport vehicle satellite positioning system, vehicle terminal function is good, it has very good practicality.
