The project describes a total length of 90 km highway, a total of 8 toll stations, each station DVR has 16 monitoring images, for color images, each flow is 500KB ~ 2M, to monitor the image of each station in the local storage, and then sent to the management Central monitoring. 16 images of each station are sent to the remote management center through the optical fiber ring network. The Korenix JetNet 4008f-s industrial Ethernet switch sets 8 sites and 1 management center to the backup ring network. The self-healing time is less than 20 milliseconds and starts. The IGMP multicast protocol improves the quality of video transmission and is monitored remotely at the management center. The framework shows that coal is an indispensable source of energy for the national economy, and mining is a very high risk. In order to enhance safety, it effectively achieves real-time positioning, tracking, elimination of human error and occurrence of various dangerous conditions for downhole personnel, guarantees the accuracy of original data collection, improves management level, and reduces economic losses.
