Due to the problems of the present monitoring system, such as the single function and bad data sharing, the coal mine Comprehensive monitoring system is designed based on the industry Ethernet. In this paper, the structural model of kilomega industry Ethernet plus CAN field- bus is adopted to establish the synthesis monitoring system and the system is divided into management layer, monitoring layer and de- vice layer.Every monitoring subsystem can be converged by the industrial Ethemet ring network delivery platform. Also according to the structure characteristics of the system, the coal mine comprehensive mono toning software is designed based on the configuration software and finally realized the congregation of the comprehensive information, also improved the level of the coal mine monitoring automation.
