摘要
无线网络技术已被广泛的应用在工业控制系统中,介质访问控制(MAC)协议作为工业控制系统无线网络通信的底层基础,是保证无线网络高效通信的关键协议.针对搭载多收发器无线终端的工业控制系统设计了一种能源有效的MAC协议—MH-MAC,该协议可根据不同网络环境和应用的需求,灵活地配置信道分配方案和介质访问策略,采用MH-RS调度算法来协调多个收发器高效工作.最后与B-MAC协议进行了比较分析,实验表明MH-MAC协议在提高网络带宽、降低传输时延、增加网络吞吐量和减少能量消耗等方面明显优于B-MAC协议,具有良好的可扩展性和实际应用价值.
In recent years,wireless network technology has been widely used in industrial control system.As the bottom foundation of wireless network communication in the industrial control system,Media Access Control(MAC) protocol is the key protocol for efficient wireless network communication.An energy-effective MAC protocol(MH-MAC) is designed directed at the industrial control system equipped with multi-radio wireless terminal.This new protocol can flexibly configure channel assignments and media access strategies according to different network environments and application requirements,and coordinate the efficient work among multiple radios through the application of MH-RS schedule algorithm.Finally,a comparison is made between MH-MAC and B-MAC to show that MH-MAC protocol is obviously superior to B-MAC protocol in increasing throughput,reducing transmission delay and decreasing energy consumption.Besides,it has great expansibility and practical value.
