Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The working principle of the scheme is briefly described as follows:

in the utility model, the first pipeline pressure sensor and the second pipeline pressure sensor respectively detect the pressure in the pipeline and respectively send the pressure to the fourth wireless communication module connected with the main control module through the first wireless communication module and the second wireless communication module, after the main control module receives the information, preset standard pressure data are extracted from the storage module for comparative analysis, when the real-time pressure is lower than a set threshold value, at the moment, the pipeline is broken possibly to cause pressure reduction, at the moment, the main control module controls the first normally open type solenoid valve driver to close the first normally open type solenoid valve, the second normally open type solenoid valve driver closes the second normally open type solenoid valve, at the moment, if the data of the first pipeline pressure sensor is still lower than the standard value, the problem is found between the first normally open type solenoid valve and the pipeline inlet, the main control module controls the first alarm driver to start the first alarm, simultaneously, the alarm lamp is opened to control alarm lamp driver, if pipeline pressure sensor's data is normal, No. two pipeline pressure sensor's data is less than the threshold value of settlement, the problem is gone out between a normally open solenoid valve and No. two normally open solenoid valves so, host system still controls an alarm driver and starts an alarm, No. two alarm lamps are opened to the simultaneous control alarm lamp driver, if pipeline pressure sensor and No. two pipeline pressure sensor's data is all normal, the problem is gone out between No. two normally open solenoid valves and pipeline export so, host system is except starting an alarm this moment, still will control the alarm lamp driver and open No. three alarm lamps. Acoustic sensor carries the acoustics leakage signal who gathers for the fast Fourier transformer through signal processor, the fast Fourier transformer carries out fast Fourier change to this acoustics leakage signal, draw corresponding spectrogram, provide visual waveform, spectral analysis, and compare this spectrogram and the spectrogram when the valve that prestores does not leak through the analysis appearance, whether leak with judge this valve, and send the data that obtains the analysis for main control module through No. three wireless communication module, when the condition of leaking appears in the valve, No. two alarms of main control module control driver start No. two alarms.

Furthermore, standard air pressure information is preset in the storage module, standard waveform information is preset in the analyzer, whether the air pressure of the pipeline is normal is judged through the preset standard air pressure information, whether the valve leaks air is judged through the preset waveform information, the design difficulty is reduced, and meanwhile the purpose is achieved more easily.

Further, the alarm lamp includes an alarm lamp, No. two alarm lamps, No. three alarm lamps, and different pipeline sections are corresponded to different alarm lamps, make things convenient for the staff to distinguish fast which section has appeared the problem, have reduced staff's work load.

Further, a normally open solenoid valve and No. two normally open solenoid valves will wait to detect the pipeline and equally divide into the three-section, and a normally open solenoid valve is close to pipeline entry one side, and No. two normally open solenoid valves are close to pipeline export one side, and the design of the different alarm lamps of cooperation can confirm that the problem has appeared in that district section on the earth fast.

Further, pipeline pressure sensor sets up between pipeline entry and a normally open solenoid valve, and pipeline pressure sensor sets up between a normally open solenoid valve and No. two normally open solenoid valves, detects respectively the pressure in different sections, and the pressure in that section is unusual, so can judge for a long time that a section has appeared the problem.

Further, the signal processor is used for amplifying and filtering the input signals, and can obtain clearer signals by amplifying and filtering the signals, so that subsequent fast Fourier converters and analyzers can perform analysis processing conveniently.

Furthermore, audible and visual alarms are adopted in the first alarm and the second alarm, and two different alarm modes of sound and light are adopted, so that the reminding effect is more obvious.

Furthermore, acoustic sensor includes a plurality ofly, evenly sets up on waiting to detect the pipeline, and different valves correspond different acoustic sensor, can reach the purpose that quick judgement that valve has appeared leaking.
