摘要
CAN总线技术有着高效的数据传输能力和强抗干扰等优势,在很多领域都有广泛应用。本文提出了一种基于CAN总线的汽车仪表显示系统的设计,选用STC89C52作为汽车仪表硬件平台的核心处理器,以u C/OS-II嵌入式操作系统作为软件平台运行程序。通过实验验证,基于CAN总线的汽车仪表比传统的汽车仪表更加稳定可靠,且在容错处理和数据交换等方面更有优势。
The efficient data transmission ability and the advantages of strong anti-interference of CAN Bus technology, make it widely applied in many fields. This paper presents a kind of automotive instrument display design system based on CAN bus, which use the STC89C52 as the core hardware platform for automotive instrument, and uC/OS-II embedded operating system as software. Through the practical operation shows that, based on the CAN bus automotive instrument stability, reliability and accuracy than the traditional instruments superior car. Based on the CAN bus in the fault-tolerant automotive instrumentation and data exchange and other aspects of anti-interference than the traditional instruments superior car.
