Sanwang Communication--mine safety comprehensive monitoring system

Introduction In order to improve the coal mine production capacity and safety production management level, the mine has to install and construct a variety of automated systems, such as: lifting, drainage, transportation, ventilation automation systems and power supply, coal preparation, industrial television, security detection systems. Most of these systems are built at different stages and are in a state of independence, such as repeated investment in communication lines, poor overall reliability, inability to communicate with each other's system information, and large amounts of maintenance. In order to integrate resources, it is necessary to establish a unified integrated automation system. The establishment of a fiber optic redundant ring network will be ground gas drainage station, coal washing plant, transformer room, wind pressure machine room and down the belt, coal mining area substation subsystems connected together, according to the distance of distance can be used single or multiple Mode fiber. In addition to these, there are various control stations in our control layer, servers in the information layer, and video systems that use switches to form ring networks to exchange data through coupling between rings. The use of the IEM7010 Gigabit Industrial Ethernet module to form the backbone network of the integrated monitoring system can not only introduce the concept of integration, but also provide a high-speed network medium for future expansion systems. By composing a complex ring-shaped redundant network, the system ensures that the links of devices in various subsystems are unblocked, and plays a very effective role in failure recovery.

Network Features The network structure of the integrated security monitoring program for mine safety consists of the field device layer, monitoring layer and management layer. Its core network consists of Ring and Dual Homing in the basic networking structure of SW-Ring. The Gigabit fiber single ring network formed on the ground and the 100M fiber single ring network composed of boreholes connect the downhole and downhole single ring in the form of Dual Homing. The reliability of this type of networking is very high. Even if the network is faulty at the interface between the two single rings and the single ring, the network can operate normally. In coal mines, this kind of demanding reliability environment is particularly suitable for this type of networking and fully reflects its advantages. Two redundant IES5026M-2GCs are used at the monitoring level to ensure that the ground equipment can be safely and reliably monitored on the ground. The core part of the whole network adopts fiber optic cable for transmission, and the IEM7010 Gigabit industrial Ethernet switch module has outstanding performance in EMC. This ensures that all kinds of data can be transmitted safely and reliably, and is almost free of all kinds of machinery and equipment in mines. influences.
