摘要
首先提出基于车载网络的客车仪表信息系统的结构,然后从硬件和软件两方面设计了以HCS12系列MCU为核心的客车仪表信息系统,使其能完成对报警开关、水温、油压、车速和转速等信号的采集、处理和发送;通过工程运用,设计达到了预期的效果。
The configuration of bus meter information system is put forward based on in-vehicle Network; the hardware and software design of such system with the MCU core of HCS12 series is presented. This system can collect, process and send information of alarm switch, water temperature, fuel pressure, vehicle speed and rotational speed. It gets expectation effect in engineering application.
