The utility model provides a kind of real time gas concentration monitoring system for the different depth that drills, including gas density collection main frame, an Acquisition Instrument and some concentration sensors, gas density collection main frame is connected by cable with concentration sensor, by being wirelessly connected with Acquisition Instrument, including a real time gas concentration monitoring module；Each concentration sensor is both secured in a protecting tube, is detected gas density information and is generated electric signal, and the electric signal is sent into gas density by cable gathers main frame；The Acquisition Instrument with computer by being wirelessly connected.The system can realize the real time gas concentration monitoring to the different depth that drills, and obtain gas density information and change in concentration feature in real time, send gas high concentration early warning in time, avoid the generation of gas accident, improve the security of underground work.The system is simple in construction, and intelligence degree is high, easy to operate. |
