Design And Study Of LON Fieldbus Structure Coal Mine Safety Supervise And Control System

The paper analyses the present coal mine safety supervise and control system, introduces LON fieldbus technology to the coal mine safety supervise and control system, has thoroughly studied the Lonworks agreement and its principle, has designed the new Lonworks field bus structure coal mine safety supervise and control system. The paper introduce the Lonworks fieldbus core technology , take the firedamp gas density supervision and measure as the example, design the simulation quantity intelligence node ; The after the debugging and the installment node gather and analyze data and the condition through field bus , realize real-time report and supervise function.The paper analyses the WebGIS development tendency and the mine digitization importance, bring forward how to use the advanced GIS technology, the network communication technology and the data bank technology, realizes the coal mine safety monitor parameter centralization monitor and the security information centralization management, the statistics and the analysis, promptly effectively manages the coal mine safety monitor information, thus effectively prevents occurring the coal mine security accident .
