Real Time Measuring and Control System Based on Regional Site Bus of Mine Ventilation Gas

In order to solve the ventilation, non power-off and other problems of a mine gas accident, a new technical basic system of a mine safety production mon itoring and control was developed and was a regional full direction comprehensive integrated real time measuring and control system in mine ventilation gas and a mine safety production measuring and control technical system of the site bus in a nervous element real time network LonWorks.Meanwhile, the mine roadway ventilation qu antity, ventilation direction, absolute air pressure sensors and the monitoring and measuring device of the ventilation quantity in the air duct were developed.With the ap plication of the system and technology to Tunlan Mine of Xishan Coal and Electric Power Group and over 70 other coal mines, the practice results showed that the new mine safety production monitoring and control technology could effectively solve the synchronous real time response and the synchronous related measuring and contro I technology in the mine, the multi pilot power-off in gas flow region and other technical problems.
