摘　　要：设计了针对小型系统的MicroCAN总线协议.该协议规范了消息机制,实现数据传输单帧与多帧接口的统一,保障数据传输的可靠性;规范了大数据量传输机制,利用打包与解包技术,保障数据传输的正确性与高效性.详细阐述了协议的实现方法.该协议已成功应用于调距桨连续数据记录仪中,测试结果表明该协议具有高可靠性和高效性的特点.MicroCAN bus protocol is designed for small system. Message mechanism is standardized in this higher CAN protocol, by which the API of multi-frame and single frame data transmission is unified, and the reliability of data transmission is ensured; also the large amount data transfer mechanism is standardized by using packet and parse technology to ensure the accuracy and efficiency of the data transmission. The protocol has been successfully used in Voyage Data Recorder, test results show that the protocol has high reliability and high efficiency.
