Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
A kind of line leakage and system of defense, including base station, central station and monitor terminal, monitor terminal make for user
Equipment, base station include data collecting system, RTU and base station GPS, and central station includes central monitoring computer and base
Stand GPS, the central station includes central monitoring computer and central station GPS, central monitoring computer connection
Central station GPS；The data collecting system is connected to RTU, and the RTU is connected to base station GPS, described
RTU, to central station and monitor terminal, communication number is carried out between central station and monitor terminal by network transmission signal by network
Include leak detection instrument, signal amplifier, wave filter and analog-digital converter according to acquisition system, leak detection instrument is arranged on pipeline
Each position, leak detection instrument are connected to signal amplifier, and signal amplifier is connected to wave filter, and wave filter is connected to modulus and turned
Parallel operation.
A kind of line leakage and defence method, step are as follows：
(1) multiple leak detection instrument are set in the diverse location of pipeline, time of collection pipeline is collected by leak detection instrument
Acoustic signals.
(2) infrasound signal amplifies by signal, filtering, after analog-to-digital conversion, is responsible for storage to RTU, RTU by network transmission
