| 摘 要： | 重型车辆车载排放测试时经常需要同时记录排放测量数据和发动机转速、扭矩等总线数据，但多数排放测试设备缺乏从车辆总线获取数据的手段，为弥补其不足，结合测试设备的功能和硬件接口，本文基于XC164-CS单片机设计了一个CAN总线信息转换输出装置，将选定的CAN总线信息解析成实际的物理量，通过D／A转换成模拟量和RS-232串口通信2种方式对外输出，并通过LCD模块同步显示发动机转速和扭矩。

| Abstract: | On-board emission measurement of heavy vehicles often need to record the emission measurement data and the data from CAN bus such as engine speed and torque. But most of the emission testing equipment lack of the ability to obtain data from vehicle bus. In order to overcome the shortage, a CAN bus information conversion and output device based on the XC164 -CS single -chip and combined with the function of test equipment and hardware interface have been designed. With the device the CAN bus information sele... |
