Abstract：The time delay effect and real-time scheduling strategy of mine industrial Ethernet network, which is under massive data flow video load, was researched. On the basis of analyzing the theoretic calculation of Ethernet network time delay based on massive data flow video load, the model of mine industrial Ethernet network was built, and the time delay effect of 100 Mbps and 1 000 Mbps industrial Ethernet when they connected video load was simulated by the method of loading data flow, which was approximative with the date flow of coal mine scene. The simulation results show that 1 000 Mbps industrial Ethernet has shorter time delay and better real-time of communication than that of 100 Mbps industrial Ethernet. In order to decrease the delayed time of transmitting massive data flow and transmit the control instruction real-time in limited network bandwidth, the strategy of load scheduling was also given, and the load scheduling strategy simulation results show that distribution scheduling strategy can decrease the time delay effect of network effectively and get the aim of transmitting and controlling in real time.
