电控系统ECU和显示器间CAN总线通信设计

The Design of CAN Communication of Bus Line Used in the Electronic Controller Unit and the Display

介绍了车辆变速电控系统(electronic controller unit, ECU)和显示器之间的CAN(controller area network)总线通信系统;并就其软、硬件设计作了比较详细的分析;最后指出了它的应用前景.研究目的在于通过将CAN总线技术应用于实际的车辆电控系统ECU与显示器之间的通信连接,探索CAN总线技术在军用车辆中应用的可行性及相比较1553B总线技术的优势.研究结果表明:虽然CAN和1553B都具有传输效率高、可靠性高、实时性好等特点,但由于CAN价格低廉,故CAN总线应用范围更广,更具竞争性.

The paper introduces the system of the communication between the Electronic Controller Unit (ECU) of autotransmission control system of the vehicles and the LED display with CAN bus line. And also the hardware and software are introduced in detail. Finally,the application prospect of this system is pointed out. The paper aims to explore feasibility and it's superiority by putting CAN bus technology into practice in communication between the ECU of autotransmission control system of the vehicles and the LED display. By comparing the two bus technology in response time, reliability and flexibility of system expansion, we can come to the conclusion that CAN bus technology has widen application scope and great competition in performance, despite the both bus technology have the characteristics of high transmission efficiency, high reliability, high real time capability, etc.
