| 摘 要： | 主要利用TI公司的多路异步收发器，TLl6C554和PHILIPS公司的SJAl000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13的设备进行远距离、多节点传输，增强了系统的通讯可靠性。

| Abstract: | A multi-channel bus protocol conversion communication system was designed by using the multi-channel asynchronous 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 software debugging method.It is convenient for the circuit system to carry out long-range multi-node transmission of the equipments with UART interface.It enhances the reliability of communication systems. |
