摘要
主要利用TI公司的多路异步收发器TL16C554和PHILIPS公司的SJA1000设计一个多路总线协议转换通讯系统。为了实现4路UART总线与CAN总线之间的相互转换过程,采用微控制器AT89S51来控制通讯数据转换,通过硬件电路实验和软件调试算法,得到了4路串行总线与CAN总线之间的相互透明转换过程。该电路系统大大方便了具有UART接口的设备进行远距离、多节点传输,增强了系统的通讯可靠性。
A multi-channel bus protocol conversion communication system was designed by using the multi-channel asyn- chronous transceiver TL16C554 of TI and SJA1000 of Philips. In order to achieve the interconversion between four-channel UART bus and CAN bus, the microcontroller AT89S51 is adopted to control the communication data conversion. The process of interconversion between four-channel serial bus and CAN bus was acquired through hardware circuit experiment and soft- ware debugging method. It is convenient for the circuit system to carry out long-range multi-node transmission of the equip- ments with UART interface. It enhances the reliability of communication systems.
