Study On Automatic Monitoring System Of Gas Drainage Borehole
2017 CHINESE AUTOMATION CONGRESS (CAC)(2017)
摘要
In view of the special conditions of gas drainage boreholes in coal mines, an automatic monitoring system of gas drainage borehole is designed, which consists of operation control, image acquisition, image transmission, record demonstration, electricity supply and explosion protection. According to the voltage level in coal mine, a three-stage transformer with wide voltage range and stable operation has been designed. Through laboratory simulation experiment, the layout scheme of camera and lighting devices are decided: when using 12W LED lights to light the borehole and setting the distance between cameras to 10m, monitoring system will be more efficiently. Monitoring experiments were carried out on site and good results were obtained.
