Abstract:

Based on the status of domestic safety monitoring system used in coal mine, a safety monitoring system is proposed, which adopt the techniques of industry ethernet and field bus to build a hybrid distributed accessing network. Industry ethernet provides a high-speed channel for the multimedia monitoring data, and the monitoring system can control distributed devices. Also, with the techniques of field bus,any distributed third-party devices can access the hybrid network and communicate seamlessly. In this paper, the structure is analyzed as well as the communication mode between control stations and substations. This system can achieve to monitor and control the devices of coal mine with the characteristics of high reliability,openness,real-time control and high communication rate etc.

Key words: centralized monitoring, distributed network, mine
