Meanwhile, when gas leaks, the leakage alarm unit 62 gives an alarm, and people near the bracket 1 can hear the alarm to know the gas leakage condition, and when no people near the bracket 1 exist, people can still know the gas leakage condition through the association terminal, so that the gas leakage condition can be timely processed.
Example 4
Referring to fig. 7, the present embodiment is different from embodiment 3 in that the gas weighing method further includes the steps of:
and S9, acquiring a human body detection condition, wherein the human body detection condition can be acquired through the image processing module 12, and the image processing module 12 is an image acquisition camera, and when the human body is not shot by the image acquisition camera, it is indicated that the human body is not detected.
And S10, acquiring a coal gas concentration value in the air. The gas concentration value is obtained through a gas concentration detection module 7, and the gas concentration detection module 7 is a gas sensor.
S11, it is determined whether or not a human body is detected, that is, whether or not the image processing module 12 detects a human body is determined. Namely whether the human body is shot by the image acquisition camera.
S12, comparing the gas concentration value with the first preset concentration value and the second preset concentration value, and judging whether the gas concentration value is higher than the second preset concentration value and lower than the first preset concentration value. The second predetermined concentration value is the highest concentration value in the air which is not dangerous for human body, for example, 5PPM maximum content allowed by the adult in the country.
And S13, when the gas concentration value is higher than the second preset concentration value and lower than the first preset concentration value and no human body is detected, controlling the weight sensor 21 to detect the weight of the gas tank 15 for preset times at intervals in preset time. When the human body is not detected, it indicates that the gas tank 15 is not in the use state, and if the detected gas concentration value is higher than the second preset value, it indicates that the gas in the gas tank 15 may leak, so it should be detected whether the gas in the gas tank 15 is reduced.
And S14, judging whether the weight of the gas tank 15 detected by the weight sensor 21 for a preset number of times within a preset time interval shows a descending trend.
S15, when the weight sensor 21 detects that the weight of the gas tank 15 reaches a descending trend within a preset time interval for a preset number of times, blowing air to the wireless sending module 4, sending gas leakage information to the associated terminal through the wireless sending module 4 in a wireless communication mode, and sending out an alarm.
The accessible of blowing to wireless sending module 4 makes the piece 10 that bloies start the realization, and the piece 10 that bloies can be the fan, and the air outlet of the piece 10 of blowing is towards wireless sending module 4 to just can blow to wireless sending module 4 when the piece 10 that bloies starts.
The alarm can be given by the leakage alarm unit 62, the leakage alarm unit 62 includes a buzzer, a warning lamp and other devices capable of giving a warning, and when people hear the sound of the buzzer or the light of the warning lamp, the gas leakage can be known.
When the weight of the gas tank 15 is reduced, the amount of gas is reduced. Therefore, the gas in the gas tank 15 may be leaked to a certain extent, and at this time, the blowing piece 10 blows the wireless sending module 4, so that the leaked gas is not easy to stay at the periphery of the wireless sending module 4, and the wireless sending module 4 is safer when finding the gas leakage information. Meanwhile, the leakage alarm unit 62 gives an alarm when gas leaks, people near the bracket 1 can hear the alarm to know the gas leakage condition, and when no people exist near the bracket 1, people can still know the gas leakage condition through the associated terminal, so that the gas leakage condition can be timely processed.
