一种车辆状态通用自动监测装置设计与实现

当前装备车辆底盘数据大都通过仪表盘进行显示,而没有对数据进行采集和存储,造成对车辆的基本状态无法进行有效的评估和故障趋势分析；针对这种情况,设计一种对车辆底盘运行参数进行采集和存储的装置,通过一个通用的多PIN接口与车辆仪表盘信号线相连,采用高速AD芯片、高速主控芯片和RS485通讯接口实现对仪表盘接线输出信号的采集、计算与数据的传输存储；应用表明,此装置解决了多种车辆底盘参数的采集记录问题,具有广泛的推广应用价值。

Design and Application of Universal Auto Test Equipment for Parameters of Vehicle Status

_{:The status data of equipment chassis is expressed through instrument board,which isnot sampled and saved.So status estimate and fault prediction is not executed effectively. A kind of auto test equipment(ATE) which samples vehicle status has been designed. The proposed ATE is connected to instrument board through the universal PIN interface. It can complete real-time vehicle statusdata collection, compute and storage through AD,CPU, and RS485. The application resultsshow that the proposed ATE can complete sample and storage according to general vehicle chassis, and it has a high application value.}
