摘要
介绍了一种新型汽车状态记录仪,该系统除包括车况参数采集、数据记录、数据统计分析等汽车行驶参数记录仪的基本功能外,集成了对汽车尾气的实时监测功能,可实时检测车辆的尾气排放。着重分析了汽车状态记录仪的硬件结构和软件流程设计,最终将本系统安装在实地运行的公交车上进行了测试。现场测试得到了预期汽车行驶过程中的各种参数,结果表明本设计方案的各项参数精确度更高,可靠性更好,更能准确、全面地反映出车辆实际行驶中的状态。
The paper introduced a new intelligent vehicle state data recorder which integrated the function of gas monitor as well as the functions of vehicle state information acquisition,data recording and data analysis. The paper is focused on the hardware structure and the software design of the system. And the field measurement was performed by installing the recorder on a bus, from which the related parameters during the bus operation were obtained. The results show that the design of the recorder possesses higher reliability and reflects the overall status of a bus under operation.
