基于MC9S12DG128的发动机仪表数据采集系统

Data Acquisition System for Engine Instrument Based on MC9S12DG128

针对具有CAN总线的发动机控制器,开发了基于MC9S12DG128的发动机仪表数据采集系统,该系统可以对发动机水温、油压、车速、转速和档位信号进行采集、处理、发送和显示。工程应用表达该系统达到了预期的开发效果。

For the engine controller with CAN bus, a data acquisition system was developed based on MC9S12DG128, which collected the water temperature, oil pressure, vehicle speed, rotational speed and stall signals, then processed and displayed the signals. The application of engineering showed the results were satisfied.
