Wang Man-yi · Yibiao jishu yu chuanganqi · 2010
Aiming at the requirements of communication real-time and reliability,this paper presented Mine-CAN protocol which was an application layer protocol based on voice warning system on the basis of CAN2.0B technology protocol,and its background was coal mine voice warning system. The paper introduced the integrated structure and the hardware of the voice warning system and researched Mine-CAN protocol from the message definition,the distribution of eleven identifiers,the definition of the frame and the communication mode.It proves the reasonableness that applies Mine-CAN protocol to coal mine voice warning system through building experiment system.
