摘要
针对舰船设备间通信,设计一种以51单片机为核心的CAN总线和RS-422串口的适配卡。对比分析了CAN总线和RS-422串口的通信特点,介绍了板卡硬件电路设计,并对软件的设计思路与流程做了详尽描述,并附相关代码。系统可靠性高,实时性好。
The adapter board for CAN bus and serial port based on the controller of 51 microchip is designed for communication between ship equipments. CAN bus and RS-422’s specialty is analyzed and compared, the design of hardware circuit is described, and the flow and design concept of program is described as well,also giving related code. The adapter board has a high reliability and a fine real time performance.
