Preferably, described gas detection sensor is infrared gas detection sensor, laser gas detecting sensor, heat-conducted gas detecting sensor or electrochemical gas detecting sensor.
Preferably, described pressure transducer is fiber bragg grating pressure sensor.
Compared with prior art, the beneficial effects of the utility model are:
(1) the comprehensive monitoring early warning to gas pipeline longer transmission stage and application area stage can be realized, full monitoring to fuel gas transmission to the whole process of user after combustion gas exploitation can be realized, can Timeliness coverage problem, respond in time;
(2) Jiao Jing on the gas pipeline of application area sets up exhaust pump, occurs in the well of cellar for storing things as leaked, and can the combustion gas of leakage be gone out from cellar for storing things well array in time, reduce the density of cellar for storing things well internal leakage combustion gas, for accident maintenance, personnel provide safety guarantee;
(3) infrasonic sensor is monitored longer transmission stage pipeline in conjunction with fiber bragg grating pressure sensor, solve the problem that when both monitor separately, rate of false alarm is high, and reduce the locating area of leakage point, be convenient to search leakage point in time, process in time;
(4) in view of the circumstance complication of application area, disturbing factor is many, uses the pipeline of jamproof gas detection sensor to application area to monitor, improves accuracy of detection;
(5) the utility model is installed on the pipeline buried underground, utilize the Jiao Jing that pipeline has been established just can realize comprehensively detecting to pipeline, not only eliminate the cost of excavation, and install simple, easy, be also convenient to the installation and maintenance of sensor or exhaust pump simultaneously.
