Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and more specifically, to an air conditioner noise detection method, an air conditioner noise detection device, an air conditioner, and a readable storage medium. Background Technology

[0002] As people's living standards continue to improve, the demands for a high-quality home environment are also increasing, and the improvement that air conditioners can bring to the living space is particularly evident. Among existing air conditioners, noise is a significant factor affecting user comfort. Users who work and live in noisy environments for extended periods will inevitably experience discomfort. Furthermore, excessive noise is also a sign of abnormal air conditioner operation.

[0003] The noise generated by the outdoor unit of an existing air conditioner is mainly produced by the operation of the compressor and fan. Since the outdoor unit is usually placed outdoors, it is difficult for users to detect whether the air conditioner is working properly through noise. By the time they notice the noise is obviously abnormal, the outdoor unit has already been worn out and is running for too long, which can cause great harm.

[0004] However, in actual use, there is a problem: the noise detection methods for air conditioners in the existing technology have low accuracy and are prone to misjudgment, which affects the user experience. Summary of the Invention

[0005] This invention addresses the technical problem of low accuracy in existing noise detection methods for air conditioners.

[0006] To address the aforementioned problems, this invention provides a noise detection method for an air conditioner. The noise detection method includes: acquiring the sound decibel value of the outdoor unit during operation after the air conditioner is running; determining the magnitude of the sound decibel value and a first decibel threshold; calculating the average sound decibel value of multiple sound decibel values ​​acquired within a time period if the sound decibel value is greater than or equal to the first decibel threshold; determining whether the outdoor unit is operating abnormally based on the comparison result between the average sound decibel value and the first decibel threshold; and issuing an abnormality indication signal if the outdoor unit is determined to be operating abnormally.

[0007] Compared with existing technologies, the technical effects achieved by this solution are as follows: The sound decibel value obtained during outdoor unit operation is the sound decibel value obtained at the moment when the noise source is determined to be the outdoor unit; when the sound decibel value is less than the first decibel threshold, it is determined that the outdoor unit is not operating abnormally, and at this time the outdoor unit is operating normally, and the air conditioner can operate in normal mode; when the sound decibel value is greater than or equal to the first decibel threshold, in order to avoid misjudgment and thus affecting the user experience, the sound decibel value needs to be detected and judged multiple times to improve the accuracy of noise detection; when the sound decibel value is greater than or equal to the first decibel threshold, the sound decibel value is obtained every second interval, and after repeating the acquisition K times, the sound decibel average of the K sound decibel values ​​is calculated. The accuracy of the sound decibel average is improved by taking the average value multiple times.

[0008] In one embodiment of the present invention, when the sound decibel value is greater than or equal to a first decibel threshold, the outdoor unit is determined to be operating abnormally based on the comparison result between the average sound decibel value and the first decibel threshold, including: when the average sound decibel value is less than the first decibel threshold, the outdoor unit is determined to be operating normally; and / or when the average sound decibel value is greater than or equal to the first decibel threshold, the outdoor unit is determined to be operating abnormally.

[0009] Compared with existing technologies, the technical effect achieved by this technical solution is as follows: if the average sound decibel value obtained after repeating K times is still greater than or equal to the first decibel threshold when the sound decibel value is greater than or equal to the first decibel threshold, it indicates that the sound decibel values ​​detected multiple times are too high, and the outdoor unit is judged to be operating abnormally.

[0010] In one embodiment of the present invention, after determining the magnitude of the sound decibel value and the first decibel threshold, the method further includes: when the sound decibel value is less than the first decibel threshold, determining that the air conditioner is operating normally.

[0011] Compared with existing technologies, the technical effect achieved by adopting this technical solution is as follows: if the source of noise is determined to be the outdoor unit, and the sound decibel value is less than the first decibel threshold, it is determined that the outdoor unit is not operating abnormally. At this time, the outdoor unit is operating normally, and the air conditioner can operate in normal mode.

[0012] In one embodiment of the present invention, the noise detection method further includes: after the air conditioner is running, acquiring the sound fluctuation value of the outdoor unit during operation; determining the source of the noise based on the sound fluctuation value; and if the source of the noise is determined to be the outdoor unit, determining whether the outdoor unit is operating abnormally based on the sound decibel value.

[0013] Compared with existing technologies, the technical advantages of this solution are as follows: In the noise detection process, the source of the noise is first determined by the sound fluctuation value to determine whether it is from the outdoor unit. If the source is determined to be the outdoor unit, the decibel value of the outdoor unit during operation is obtained. This decibel value can then be used to determine whether the outdoor unit is operating abnormally. If the sound fluctuation value indicates that the source of the noise is not the outdoor unit but its installation environment, then there is no need to obtain and determine the decibel value subsequently. By first determining whether the source of the noise is the outdoor unit, and then deciding whether to obtain the decibel value and determine whether the outdoor unit is operating abnormally based on the decibel value, this design in the noise detection method saves steps, reduces unnecessary judgment and detection steps, and makes the detection process more efficient.

[0014] In one embodiment of the present invention, determining the source of noise based on sound fluctuation value includes: determining whether the source of noise is the outdoor unit installation environment based on the comparison result of sound fluctuation value and a first fluctuation threshold; if the source of noise is determined to be not the outdoor unit installation environment, obtaining the sound fluctuation value at a second time after an interval of a first time interval; and determining whether the source of noise is the outdoor unit based on the comparison result of the sound fluctuation value at the second time and the second fluctuation threshold.

[0015] Compared with existing technologies, the technical effects achieved by this solution are as follows: when the sound fluctuation value is less than the first fluctuation threshold, it is determined that the source of the noise is not the outdoor unit installation environment. In the case that the source of the noise is determined to be not the outdoor unit installation environment, in order to avoid misjudgment, the sound fluctuation value at the second moment is obtained after the first interval. Based on the comparison between the sound fluctuation value at the second moment and the second fluctuation threshold, it is further determined whether the source of the noise is the outdoor unit, thus improving the accuracy of the judgment method.

[0016] In one embodiment of the present invention, when it is determined that the source of the noise is not the outdoor unit installation environment, the determination of whether the source of the noise is the outdoor unit is based on the comparison result of the sound fluctuation value at the second moment and the second fluctuation threshold, including: when the sound fluctuation value at the second moment is greater than or equal to the second fluctuation threshold, it is determined that the source of the noise is not the outdoor unit; and / or when the sound fluctuation value at the second moment is less than the second fluctuation threshold, it is determined that the source of the noise is the outdoor unit.

[0017] Compared with existing technologies, the technical effect achieved by this technical solution is as follows: when it is initially determined that the source of the noise is not the outdoor unit installation environment, the source of the noise can be further determined based on the comparison between the sound fluctuation value at the second moment and the second fluctuation threshold, thereby improving the accuracy of the judgment method.

[0018] In one embodiment of the present invention, after the air conditioner issues an abnormal indication signal when it is determined that the outdoor unit is operating abnormally, the noise detection method further includes: determining whether the air conditioner receives a first operation signal from the transmitter; if so, the air conditioner adjusts its current operating state according to the first operation signal; when the first operation signal is to operate a first button, the air conditioner is controlled to stop; and / or when the first operation signal is to operate a second button, the abnormal indication signal is ignored, and the sound decibel value is not acquired again during a first ignoring period.

[0019] Compared with existing technologies, the technical effects achieved by this solution are as follows: When the outdoor unit is determined to be operating abnormally, the air conditioner issues an abnormality indication signal, reminding the user to check the outdoor unit according to the signal. The air conditioner then controls its subsequent operation based on the first operation signal it receives. Once the user checks and confirms that the outdoor unit is indeed operating abnormally, the air conditioner shuts down to prevent further malfunctions. If the user checks and confirms that the outdoor unit is functioning normally, it can resume normal operation. To avoid misjudgment, a first grace period can be selected to refrain from further testing.

[0020] In another aspect, embodiments of the present invention also provide a noise detection device for an air conditioner, the noise detection device comprising: an acquisition module, configured to acquire the sound decibel value and sound fluctuation value of the outdoor unit during operation after the air conditioner is running; a first judgment module, configured to judge the magnitude of the sound decibel value and a first decibel threshold; a calculation module, configured to calculate the average sound decibel value of multiple sound decibel values ​​acquired within a time period when the sound decibel value is greater than or equal to the first decibel threshold; a second judgment module, configured to judge whether the outdoor unit is operating abnormally based on the comparison result between the average sound decibel value and the first decibel threshold; and a prompting module, configured to issue an abnormal indication signal when the outdoor unit is judged to be operating abnormally.

[0021] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: The noise detection device of the air conditioner in this embodiment is used to implement the noise detection method of the air conditioner as in any embodiment of the present invention, and therefore it has all the beneficial effects of the noise detection method of the air conditioner as in any embodiment of the present invention, which will not be repeated here.

Detailed Implementation

[0039] To make the above-mentioned objectives, features, and advantages of the present invention more apparent and understandable, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Example 1

[0041] See Figure 1 This is a flowchart of a noise detection method for an air conditioner provided in the first embodiment of the present invention, combined with... Figure 2 Noise detection methods include:

[0042] After the air conditioner is running, obtain the sound fluctuation value of the outdoor unit during operation;

[0043] Determine the source of noise based on sound fluctuation values;

[0044] If the noise source is determined to be the outdoor unit, the decibel level of the sound can be used to determine whether the outdoor unit is operating abnormally.

[0045] In one specific embodiment, when the air conditioner is turned on, it monitors the decibel and fluctuation values ​​of the outdoor unit's sound in real time. During noise detection, the sound fluctuation value is used first to determine whether the noise source is the outdoor unit. If the source is determined to be the outdoor unit, the decibel value of the outdoor unit's sound during operation is obtained. This decibel value can be used to determine whether the outdoor unit is operating abnormally. If the sound fluctuation value indicates that the noise source is not the outdoor unit but rather its installation environment, then further acquisition and judgment of the decibel value is unnecessary.

[0046] Furthermore, by first determining whether the noise source is the outdoor unit and then determining whether to obtain the sound decibel value, the outdoor unit can be judged to be operating abnormally based on the sound decibel value. This design in the noise detection method can save more steps, reduce unnecessary judgment and detection steps, and make the detection process more efficient.

[0047] Preferably, the acquisition module can be a sound sensor or a noise detector; the type of abnormal indication signal is not limited, and the abnormal indication signal may include, but is not limited to: continuous flashing of the indicator light or continuous alarm.

[0048] Furthermore, noise detection methods include:

[0049] After the air conditioner is running, obtain the decibel value of the outdoor unit's sound during operation;

[0050] Determine the magnitude of the sound decibel value and the first decibel threshold;

[0051] If the sound decibel value is greater than or equal to the first decibel threshold, calculate the average sound decibel value of multiple sound decibel values ​​obtained within the time period;

[0052] Based on the comparison between the average decibel level and the first decibel threshold, determine whether the outdoor unit is operating abnormally;

[0053] If the outdoor unit is determined to be operating abnormally, the air conditioner will issue an abnormality indication signal.

[0054] In one specific embodiment, when the noise source is determined to be the outdoor unit, the current sound decibel value is output, and compared with a first decibel threshold. When the sound decibel value is less than the first decibel threshold, the outdoor unit is determined to be operating normally, and the air conditioner can operate in normal mode. When the sound decibel value is greater than or equal to the first decibel threshold, to avoid misjudgment and affecting user experience, the sound decibel value needs to be detected and judged multiple times to improve the accuracy of noise detection. The first decibel threshold is obtained and determined through experimental testing, and is a fitted value generated by comparing different compressor frequencies and fan speeds. The obtained sound decibel value during outdoor unit operation is the sound decibel value obtained at the moment when the noise source is determined to be the outdoor unit.

[0055] The specific process of multiple tests is as follows: when the sound decibel value is greater than or equal to the first decibel threshold, the sound decibel value is acquired at second intervals. After repeating this process K times, the average sound decibel value of the K acquisitions is calculated. This method of averaging multiple acquisitions improves the accuracy of the average sound decibel value. Here, K is the number of times the sound decibel value is acquired.

[0056] After calculating the average decibel level of the sound, the air conditioner determines whether the outdoor unit is operating abnormally based on the comparison between the average decibel level and the first decibel threshold. If the outdoor unit is found to be operating abnormally, the air conditioner will issue an abnormality indication signal to remind the user to check and judge the abnormality indication signal.

[0057] Preferably, to eliminate misjudgments caused by the sound fluctuation values ​​of the outdoor unit's installation environment and the outdoor unit itself falling within the same range, during multiple tests, the sound fluctuation value must first be obtained. If the noise source is determined to be the outdoor unit based on the sound fluctuation value, the sound decibel value at that moment is obtained to calculate the average sound decibel value. This process is repeated K times to finally calculate the average sound decibel value.

[0058] Preferably, the second interval duration is 2 minutes; to ensure the accuracy of detection and prevent misjudgment, K≥3.

[0059] Furthermore, when the sound decibel value is greater than or equal to the first decibel threshold, the outdoor unit is judged to be operating abnormally based on the comparison between the average sound decibel value and the first decibel threshold, including:

[0060] When the average sound level in decibels is less than the first decibel threshold, the outdoor unit is considered to be operating normally; and / or

[0061] When the average decibel level of the sound is greater than or equal to the first decibel threshold, the outdoor unit is judged to be operating abnormally.

[0062] In a specific embodiment, if the average sound decibel value obtained after repeating K times is still greater than or equal to the first decibel threshold when the sound decibel value is greater than or equal to the first decibel threshold, it indicates that the sound decibel values ​​detected multiple times are too high, and the outdoor unit is judged to be operating abnormally.

[0063] Furthermore, after determining the magnitude of the sound decibel value and the first decibel threshold, the following steps are also included:

[0064] When the sound decibel value is less than the first decibel threshold, the air conditioner is judged to be operating normally.

[0065] In one specific embodiment, if the noise source is determined to be the outdoor unit, and the sound decibel value is less than the first decibel threshold, it is determined that the outdoor unit is not operating abnormally. At this time, the outdoor unit operates normally, and the air conditioner can operate in normal mode.

[0066] Furthermore, determining the source of noise based on sound fluctuation values ​​includes:

[0067] Based on the comparison between the sound fluctuation value and the first fluctuation threshold, determine whether the source of the noise is the outdoor unit installation environment;

[0068] If the source of the noise is determined to be outside the outdoor unit installation environment, the sound fluctuation value at the second moment is obtained after the first interval.

[0069] Based on the comparison between the sound fluctuation value at the second moment and the second fluctuation threshold, it is determined whether the source of the noise is the outdoor unit.

[0070] In one specific embodiment, based on the comparison between the sound fluctuation value and a first fluctuation threshold, it can be preliminarily determined whether the source of the noise is the outdoor unit installation environment. Since the noise from an indoor unit malfunction is relatively persistent and stable, the sound fluctuation value is generally small. Therefore, when the sound fluctuation value is greater than or equal to the first fluctuation threshold, the source of the noise is determined to be the outdoor unit installation environment. When the sound fluctuation value is less than the first fluctuation threshold, the source of the noise is determined not to be the outdoor unit installation environment. In cases where the source of the noise is determined not to be the outdoor unit installation environment, to avoid misjudgment, after a first interval, the sound fluctuation value at a second moment is obtained. Based on the comparison between the sound fluctuation value at the second moment and the second fluctuation threshold, it is further determined whether the source of the noise is the outdoor unit, thus improving the accuracy of the determination method. Specifically, the sound fluctuation value is calculated from the sound fluctuations monitored within a first set time period; the first fluctuation threshold is obtained and determined by experimental testing and is the noise fluctuation value generated by the outdoor unit itself due to frequency conversion; the source of the noise is the outdoor unit installation environment, meaning that the source of the noise may be one or more of the following: noisy traffic noise, nearby construction noise, etc.

[0071] Preferably, the preferred value for the first interval duration is 1 minute; the preferred value for the first set duration is 20 seconds.

[0072] Furthermore, if the noise source is determined to be outside the outdoor unit's installation environment, the comparison between the sound fluctuation value at the second moment and the second fluctuation threshold is used to determine whether the noise source is the outdoor unit, including:

[0073] When the sound fluctuation value at the second moment is greater than or equal to the second fluctuation threshold, the source of the noise is determined to be not the outdoor unit; and / or

[0074] When the sound fluctuation value at the second moment is less than the second fluctuation threshold, the source of the noise is determined to be the outdoor unit.

[0075] In one specific embodiment, if it is initially determined that the source of the noise is not the outdoor unit installation environment, when the sound fluctuation value at the second moment is greater than or equal to the second fluctuation threshold, it is determined that the source of the noise is not the outdoor unit; when the sound fluctuation value at the second moment is less than the second fluctuation threshold, it is determined that the source of the noise is the outdoor unit.

[0076] The second fluctuation threshold is obtained and determined by experimental testing. It is a sound fluctuation value generated at the same frequency that has been verified by actual simulation.

[0077] Furthermore, when the outdoor unit is determined to be operating abnormally, and the air conditioner issues an abnormality indication signal, the noise detection method also includes:

[0078] Determine whether the air conditioner receives the first operation signal from the transmitter;

[0079] If so, the air conditioner adjusts its current operating status according to the first operation signal;

[0080] When the first operation signal is an operation of the first button, the air conditioner is controlled to stop; and / or

[0081] When the first operation signal is to operate the second button, the abnormal indication signal is ignored, and the sound decibel value is not acquired again during the first ignore duration.

[0082] In one specific embodiment, when the outdoor unit is determined to be operating abnormally, the air conditioner issues an abnormality indication signal to remind the user to check the outdoor unit according to the abnormality indication signal, and controls the subsequent operation of the air conditioner according to the first operation signal received by the air conditioner. The system determines whether the air conditioner receives the first operation signal from the transmitter: if the first operation signal is pressing the first button, it means the user has checked and confirmed that the outdoor unit is indeed operating abnormally, therefore the air conditioner is controlled to stop to prevent abnormal operation of the outdoor unit; if the first operation signal is pressing the second button, it means that after the user's check, it is confirmed that the outdoor unit is not abnormal, and the noise detected by the outdoor unit may be continuous ambient noise, therefore the outdoor unit can continue to operate normally. The user can also choose to ignore the abnormality indication signal, and will not acquire sound decibel values ​​again during the first ignore period to avoid misjudgment during the first ignore period.

[0083] Preferably, there is no limitation on the type of transmitter, which may include, but is not limited to: air conditioner remote control, mobile phone, smartwatch.
