	Design of CAN bus application layer protocol for aerocraft control system (EI CONFERENCE) 会议论文 OAI收割 2010 2nd International Conference on Industrial Mechatronics and Automation, ICIMA 2010, May 30, 2010 - May 31, 2010, Wuhan, China 作者: Zhang Y.; Zhang H.; Zhang H.; Zhang W.; Zhang W. 收藏 \| 浏览/下载：33/0 \| 提交时间：2013/03/25 A special Controller Area Network (CAN) bus application layer protocol is designed for the highly reliable communication of microcomputer-based systems in aerocraft control system by analyzing the practical time sequence of data transmission data priority data type and data function etc in this paper. Identifier distribution data storage form data type data exchange method and fault handling mechanism of the application layer protocol are specified in detail in the background of a real aerocraft control system. At last a simulation platform based on CAN bus for aerocraft control system is built to validate the design. Experimental results show that this application layer protocol meets the requirements of data transmission reliability real-time and high efficiency. The bus load rate is low and there is great room for expansion. 2010 IEEE.
