oasaesoaoossseaeaee monitoring shearer position, working reliability and real-time performance is difficult to meet the requirements of the system in the harsh environment and complex fully mechanized working face. studies A spray and dust suppression system of fully mechanized mining face based on CAN bus and wireless sensor networks( WSNs ) technology. The ZigBee terminal node of WSNs is installed on the shearer body for collecting and transmitting operation state of equipment. The routing node is transmitted to the hydraulic support through WSNs, and location of the shearer can be determined in realtime according to the location algorithm. Each routing node is connected through CAN bus to ensure the high efficiency and reliability, and the data is finally uploaded to the ground database through the ground CAN bus interface. Finally, the feasibility of monitoring network communication is verified by simulation experiments.

0引言
综采工作面采煤机截割煤岩时产生大量粉尘,虽然采煤机自身携带内喷雾降尘装置,但效果甚微,通常在综采工作面液压支架上安装外喷雾降尘装置弥补采煤机内喷雾降尘装置的不足(1.2)。文献[3,4]对综采工作面采煤机外喷客系统进行了深人研究和改进,提高了综采工作面采煤机外喷雾系统的喷雾降尘效率。以上研究多采用红外传感装置对采煤机运行位置进行检测,在实际综采工作面中得到广泛应用,但也存在一定的弊端。
