As shown in fig. 1, the present embodiment provides a gas leakage monitoring system, which includes a volume recognition module 1, a first timing module 2, an audio recognition module 3, a second timing module 4, an electrical signal converter 5, and a monitoring system 6. The volume identification module 1 is used for detecting the volume of noise and judging whether the volume is in a set air leakage volume range, and the first timing module 2 is electrically connected with the volume identification module 1 and is used for timing the duration that the volume of the noise is continuously in the set air leakage volume range.

The second timing module 4 is electrically connected with the audio recognition module 3 and is used for timing the duration that the noise audio is continuously within the set air leakage audio range. An electrical signal transducer 5 is electrically connected to the second timing module 4 for forming an electrical signal indicative of an air leak. The monitoring system 6 is electrically connected with the electric signal converter 5 and is used for receiving and displaying the electric signal.
In order to ensure that the worker receives the signal of air leakage in time, optionally, the air leakage monitoring system further comprises a communication module 7 and a client 8, the communication module 7 is electrically connected with the second timing module 4, and the communication module 7 is in communication connection with the client 8. Namely, when the system recognizes that the noise is caused by air leakage, the second timing module 4 triggers the communication module 7, the communication module 7 is in communication connection with the client 8, so that the signal of air leakage is sent to the client 8, and the worker can timely receive the condition of air leakage at the client 8. Optionally, the communication module 7 includes a signal transmitter, and the client 8 includes a signal receiver, and the signal transmitter and the signal receiver are communicatively connected.
In order to further facilitate the search of the air leakage position for the staff, optionally, the air leakage monitoring system further includes a position detection module, the position detection module is used for detecting the air leakage occurrence position, and the position detection module is electrically connected with the electrical signal converter 5. When air leakage is determined to occur, the electric signal converter 5 converts the electric signal into a corresponding electric signal and triggers the position detection module to start, and air leakage position detection is started. Optionally, the position detection module includes a plurality of volume detectors, and the volume detectors are respectively disposed at a plurality of positions where air leakage is likely to occur. Noise volumes at a plurality of positions detected by the volume detector are transmitted to the electric signal converter 5 and finally transmitted to the monitoring system 6, so that workers can know the noise volumes of all positions through the monitoring system 6, and the air leakage position can be judged.
Optionally, the gas leakage monitoring system further includes a power supply, and the power supply is electrically connected to the volume recognition module 1, the first timing module 2, the audio recognition module 3, the second timing module 4, and the electrical signal converter 5. Optionally, the gas leakage monitoring system further comprises a solar panel electrically connected with the power supply. Optionally, the power source is a battery. The solar cell panel and the storage battery are matched for power supply, so that energy conservation and emission reduction can be realized, and the applicability of the gas leakage monitoring system is improved.
The embodiment also provides a circuit breaker, including foretell gas leakage monitoring system to whether monitoring circuit breaker leaks gas. The circuit breaker can timely and accurately monitor the self gas leakage condition and send out signals to enable workers to know the gas leakage condition, so that normal and stable operation of equipment is guaranteed.
The embodiment also provides a gas leakage monitoring method, when the noise volume is within the set gas leakage volume range, the first timing module 2 is triggered to time, when the first set time length is reached, the audio recognition module 3 is triggered to start, when the noise audio is recognized to be within the set gas leakage audio range, the second timing module 4 is triggered to time, and when the second set time length is reached, the electric signal converter 5 is triggered to transmit a gas leakage signal to the monitoring system 6.
Because the volume of the breaker is very high when air leakage occurs, whether air leakage occurs or not can be judged through volume identification in the first step. Specifically, the volume recognition module 1 is in an on state at ordinary times, and when the noise volume detected by the volume recognition module 1 is not within the set air leakage volume range, the first timing module 2 cannot be triggered to time, and only when the noise volume detected by the volume recognition module 1 is within the set air leakage volume range, the first timing module 2 can be triggered to start timing. Because the circuit breaker normally works, the sound that conventional mechanism deciliter action arouses is also in setting for gas leakage volume range, so through first timing module 2, can calculate the time that the noise lasts, avoids arousing the condition of erroneous judgement gas leakage because automatic air supplement under circuit breaker normal action and the normal condition, increases this gas leakage monitoring system's reliability. Optionally, when the timing duration a of the first timing module 2 does not reach the first set duration, and the noise volume detected by the volume recognition module 1 changes to be outside the set air leakage volume range, the timing duration a returns to zero. The timing strategy can prevent the noise generated in normal work from being judged as air leakage by mistake. Optionally, the air leakage volume range is set to be 87-110 db, the first set time duration is 90 seconds, that is, only when the noise volume is within the time duration of more than 90 seconds and is always within the set air leakage volume range, the first timing module 2 triggers the audio recognition module 3 to perform subsequent recognition and judgment. Of course, the set air leakage volume range can be adjusted according to the set position of the volume recognition module 1, and the first set time length can also be adjusted according to the actual situation.
After the audio recognition module 3 is triggered to be turned on, when the noise audio detected by the audio recognition module 3 is not within the set air leakage audio range, the second timing module 4 cannot be triggered to time. Optionally, at this time, the audio recognition module 3 is set to be turned off, the timing duration a returns to zero, the first timing module 2 is turned off, the volume recognition module 1 re-determines whether the noise volume is within the set air leakage volume range, and the first timing module 2 is restarted to perform timing when the noise volume meets the set range, so as to eliminate interference of other noises in the environment. The second timing module 4 can be triggered to start timing only when the noise audio frequency detected by the audio frequency identification module 3 falls within the set air leakage audio frequency range.
Because the air supplement action may be caused after air leakage occurs, the pressure of the leaked air in a period of time is considered to be not changed greatly, namely, the audio frequency in the air leakage process is not changed greatly, namely, the audio frequency of the air leakage noise in a period of time is within the set air leakage audio frequency range. The timing strategy of the second timing module 4 comprises: when the timing duration B of the second timing module 4 does not reach the second set duration and the noise audio frequency changes to be out of the set air leakage audio frequency range, the timing duration B returns to zero. Therefore, the interference of environmental noise can be further eliminated, and the misjudgment is avoided. Optionally, when the timing duration B returns to zero, the second timing module 4 is turned off, the audio recognition module 3 re-recognizes the noise audio, and when the noise audio is within the set air leakage audio range, the second timing module 4 is turned on again. Optionally, the air leakage audio frequency range is set to be 1100 hz to 1900 hz, the second set time duration is 90 seconds, only when the noise audio frequency is within the set air leakage audio frequency range all the time within 90 seconds, the noise is considered to be originated from the air leakage, and at this time, the second timing module 4 triggers the electrical signal converter 5, converts the noise into a corresponding electrical signal and transmits the electrical signal to the monitoring system. Of course, the set air leakage audio frequency range can be adjusted according to the set position and the actual situation of the audio frequency identification module 3, and the second set time length can also be adjusted according to the actual situation.
This gas leakage monitoring system, circuit breaker and gas leakage monitoring method, can be through the volume of discernment noise, long with taking place, judge whether take place to leak gas, when the gas leakage is taken place to the affirmation, convert corresponding signal of telecommunication and transmit to monitoring system into through signal of telecommunication transducer 5, the staff can see monitoring system and show the gas leakage signal, just can in time accurately master the condition that the circuit breaker took place to leak gas to in time deal with the processing, with the normal steady operation of guarantee equipment.
Example two
The embodiment discloses a gas leakage monitoring method, and the difference between the gas leakage monitoring method in the embodiment and the gas leakage monitoring method in the first embodiment is as follows: when the timing duration B of the second timing module 4 does not reach the second set duration, the noise audio frequency changes to be out of the set air leakage audio frequency range, and the timing duration B returns to zero, the second timing module 4, the audio frequency identification module 3 and the first timing module 2 are all closed, the volume identification module 1 judges whether the noise volume is in the set air leakage volume range again, and the first timing module 2 is restarted to time when the noise volume accords with the set range, so that the interference of other noises in the environment is eliminated.
In addition, the rest of the contents of the gas leakage monitoring method provided in this embodiment are the same as those of the gas leakage monitoring method in the first embodiment, and are not described herein again.
