【摘要】 CAN总线是一种有效支持分布式控制和实时控制的串行通信总线。煤矿安全监控系统通信实时要求高,单次通信量小,非常适合采用CAN总线。文章提出了一种基于CAN总线的煤矿安全监控系统,并对系统网络拓扑结构、网络参数、通信协议作了详细阐述。更多还原

【Abstract】 CAN Bus is one kind of serial communication Bus which support distributed control and real-time control effectively.In coal mine,the real-time requirement of communication of safety monitoring system is critical and each communication traffic is little,so the system is suited for CAN Bus.In this paper,a safety monitoring and control system in coal mine based on CAN Bus was introduced,the design of structure for network,parameter assignment for network,communication protocol were described in detail.更多还原
