摘要
基于MC9S08DZ32单片机设计了复用电源导线的客车CAN总线控制系统,介绍了系统的硬件构成,分析了主要部件和器件的选型原则,描述了系统的软件框架,通过电力线载波芯片LM1893可将电力线数据进行合理转换,提供给网络节点,同时可以将网络节点的发送的数据信号进行合理变换,通过电力线传送给上位机。系统软件运行于uc/os嵌入式操作系统,充分利用了MC9S08DZ32单片机的软件资源,最大程度简化了硬件电路,提高了系统的可靠性和稳定性,使系统具有高的性价比。
Microcontroller based design of power line carrier MC9S08DZ32 network node controller area network control system,describes the hardware structure,analysis of main components and devices,the principle of selection,describes the system＇s software framework,through the power line carrier chip LM1893 can be Power Line reasonable conversion,provided to the network nodes,network nodes can also send a reasonable transformation of data signals through power lines to send to the host computer.Full use of the whole system MC9S08DZ32 SCM software resources,the greatest degree simplify the hardware circuit,improved reliability and stability of the system,the system has a high price.
