With the improvement of people's living standards, the requirements for high-quality life for the home environment are also getting higher and higher. Among them, the improvement of space environment by air conditioners is even more obvious. In existing air conditioners, noise is an important factor affecting user comfort. If users work and live in a noisy environment for a long time, it will inevitably lead to user discomfort. At the same time, excessive noise is also a cause of abnormal operation of the air conditioner. Performance.

The noise generated by the existing outdoor unit of the air conditioner is mainly generated 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 normally through the noise. Only when there is an obvious abnormality in the noise will they pay attention. By then, the outdoor unit of the air conditioner will have been running at a loss. Once it runs for too long, the harm will be huge.

During the noise detection process, priority is given to judging whether the source of the noise is an outdoor unit through the sound fluctuation value. If the source of the noise is judged to be an outdoor unit, the sound decibel value of the outdoor unit when it is running is obtained. The outdoor unit can be judged by the sound decibel value. Whether it is abnormal operation; if it is judged from the sound fluctuation value that the source of the noise is not the outdoor unit, but the installation environment of the outdoor unit, then there is no need to obtain and judge the subsequent sound decibel value.

The sound decibel value obtained at the moment.

The specific process of multiple detections is: 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 repeated acquisition K times, the average sound decibel value of the K sound decibel values is calculated. A method of averaging multiple acquisitions to improve the accuracy of the sound decibel mean. Among them, K is the number of times to repeatedly obtain the sound decibel value.

After calculating the average sound decibel value, it is determined whether the outdoor unit is operating abnormally based on the comparison result between the average sound decibel value and the first decibel threshold. When it is determined that the outdoor unit is operating abnormally, the air conditioner sends an abnormal indication signal for Users are reminded that they need to check and judge abnormal indication signals.

Preferably, in order to eliminate misjudgment caused by the sound fluctuation value of the outdoor unit installation environment noise and the sound fluctuation value of the outdoor unit being in the same range. In the process of multiple detections, the sound fluctuation value needs to be obtained first. When the noise source is judged to be an outdoor unit based on the sound fluctuation value, the sound decibel value at that moment is obtained and used to calculate the average sound decibel value, and is repeated K times.
