发布时间：2018-10-09 14:22
【摘要】：汽车行驶记录仪的使用，对遏制交通违章、约束驾驶人的不良驾驶行为、保障车辆行驶安全以及道路交通事故的分析鉴定具有重要的作用。新一代的卫星定位行车记录仪不仅具备以上功能，同时还兼具对车辆实时监管、问题警示、防抢、防盗及事故前提醒、事故后报警求救等。目前，中国自主的北斗定位系统已经相对成熟，为了响应国家推广北斗终端的号召，全球定位系统使用北斗定位。 系统采用ARM9控制器MB9G711及其他功能组件，设计了一种卫星定位行车记录仪。功能组件包括：电源控制电路、液晶显示电路、打印机驱动电路、北斗模块及GPRS模块控制电路等。分析了系统存在的干扰，并提出了抑制措施。 移植了以色列开源操作系统EFOS，并在其框架下完成了相关硬件驱动程序的编写；使用北斗定位系统进行地理信息的采集，，在卫星信号较弱时过滤掉不连续的跳变数据；利用三轴加速度传感器计算水平度，详细分析了计算侧翻的工作原理及相关算法；使用射线法对电子围栏进行计算，从而判断出车辆是否按照预定路线或区域行驶。 对研制的卫星定位行车记录仪进行了大量的实验，各项指标均达到设计要求，具有较强的抗干扰能力，先后通过了国家标准及行业标准的认证，目前已经批量生产。
[Abstract]:The use of the vehicle driving recorder plays an important role in curbing traffic violations, restraining the bad driving behavior of the driver, ensuring the safety of the vehicle and the analysis and identification of the road traffic accident. The new generation of satellite positioning CarLog not only has the above functions, but also has real-time vehicle supervision, problem warning, anti-robbery, anti-theft and pre-accident reminders, and calls for help after the accident. At present, China's independent Beidou positioning system has been relatively mature, in response to the national call to promote the Beidou terminal, the Global Positioning system uses Beidou positioning. The system uses ARM9 controller MB9G711 and other functional components to design a satellite positioning CarLog. Functional components include: power control circuit, LCD circuit, printer drive circuit, Beidou module and GPRS module control circuit. The interference of the system is analyzed and the suppression measures are put forward. In this paper, the Israeli open source operating system EFOS, is transplanted and the related hardware driver is compiled under its framework. The Beidou positioning system is used to collect geographic information and filter out the discontinuous jump data when the satellite signal is weak. Using the three-axis acceleration sensor to calculate the horizontal degree, the working principle and the related algorithm of calculating the rollover are analyzed in detail, and the electronic fence is calculated by the ray method to determine whether the vehicle is running according to the predetermined route or area. A large number of experiments have been carried out on the developed satellite positioning CarLog, each index has reached the design requirements and has strong anti-interference ability. It has passed the certification of national standard and industry standard successively, and has been produced in batches at present.
