Detailed Description
For a better understanding of the above technical solutions, exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.
The following describes a noise reduction method and device for an air conditioner, the air conditioner and an electronic device according to an embodiment of the present application with reference to the drawings.
Fig. 1 is a schematic flowchart of a noise reduction method for an air conditioner according to an embodiment of the present disclosure.
As shown in fig. 1, the noise reduction method of the air conditioner includes the steps of:
s101, acquiring a current signal of a compressor in the air conditioner.
When the current signal of the compressor in the air conditioner is tried to be acquired, the current can be acquired through the arranged current acquisition unit so as to acquire the current signal of the compressor.
S102, collecting a current noise signal of a compressor in the air conditioner.
In the present application, a collecting device related to a noise signal is provided at a valve of the outdoor unit or a box of the outdoor unit. Wherein, the collection device can collect in real time or periodically. The period can be set according to actual conditions.
Generally, the current noise signal of the compressor in the air conditioner can be obtained by collecting at least one of the suction and discharge pulsation noise signal and the rotation noise signal.
Alternatively, as shown in fig. 2(a), at least one sound collector may be disposed at the large and small valve ports of the outdoor unit to collect suction and discharge pulsation noise signals of the compressor.
Alternatively, as shown in fig. 2(b), at least one sound collector may be provided on the casing of the outdoor unit to collect a rotation noise signal of the compressor. Further, under the condition that two or more noise signals are obtained, one fused noise signal can be obtained through algorithms such as weighted fusion, and the like, the fused noise signal can be used for representing the actual noise condition of the compressor, and the fused noise signal is used as the current noise signal of the compressor in the application. For example, noise signals a and B are collected at a box of the outdoor unit, and the weighting coefficients corresponding to the noise signals a and B are a and B, respectively.
And S103, acquiring a noise reference signal according to the current signal and the noise signal.
As a possible implementation manner, a mapping relationship between the current signal and the noise reference signal may be preset, and after the current signal and the noise signal are obtained, the corresponding noise reference signal may be obtained by querying the mapping relationship. The mapping relation can be a mapping table, a specific mapping formula, established through specific tests, or an established machine learning model, and the model is used for acquiring the noise reference signal.
S104, controlling the sound generator to generate secondary noise according to the noise reference signal; wherein the secondary noise interferes with the primary noise of the compressor to reduce the noise of the compressor.
In the present application, a plurality of sound generators are provided at the suction/discharge port of the compressor, the casing of the compressor, or the like.
Alternatively, as shown in fig. 2(a), a plurality of sound generators are provided at the suction/discharge port of the compressor.
Alternatively, as shown in fig. 2(b), which is a schematic front side view and a schematic top view of an outdoor unit of an air conditioner, a sound generator is provided on at least one side of a casing of a compressor. In practical application, the outdoor fan may generate noise when operating, and when the secondary noise generated by the sound generator interferes with the original noise of the compressor, the secondary noise may be superimposed with the noise of the fan, and the noise of the fan may be increased.
After the noise reference signal is acquired, a noise generation instruction for the sound generator may be generated according to the noise reference signal, and the noise generation instruction may be input to the sound generator so that the sound generator generates secondary noise according to the noise generation instruction. Wherein the secondary noise interferes with the primary noise of the compressor to reduce the noise of the compressor. The sound generator may be selected according to actual conditions, and for example, the sound generator may be selected to be a microphone.
The technical scheme in the embodiment of the application at least has the following technical effects or advantages:
the noise reference signal can be obtained based on the obtained current signal and the obtained noise signal, and then secondary noise which can interfere with the original noise of the compressor is actively generated according to the noise reference signal so as to reduce the noise of the compressor. In addition, the secondary noise can be dynamically updated along with different original noise signals of the compressor, so that a better noise reduction effect can be obtained under any working condition or any compressor operation frequency, and the problems of poor applicability and non-ideal noise reduction effect are fundamentally solved.
In theory, after the sound generator is controlled to generate the secondary noise according to the noise generation command, the secondary noise interferes with the original noise of the compressor, the noise peak is cancelled, and the noise residual value signal can be set to 0. However, in practical applications, the practical reduction effect is affected to some extent due to limitations of device sensitivity, calculation speed, and the like. Therefore, after controlling the sound generator to generate the secondary noise according to the noise generation instruction, the noise residual value signal after the interference is performed can be acquired, and whether the noise residual value signal meets the allowed noise condition or not can be judged. If the identified noise residual signal does not satisfy the allowed noise condition, new secondary noise may continue to be acquired to reduce the noise of the compressor until the identified noise residual signal satisfies the allowed noise condition.
As a possible implementation manner, as shown in fig. 3, the method specifically includes the following steps:
s201, collecting a noise residual value signal after the secondary noise interferes with the original noise of the compressor.
The air conditioner can be controlled to receive a signal fed back after the secondary noise interferes with the original noise of the compressor, and the signal is marked as a noise residual value signal.
S202, judging whether the noise residual value signal meets the noise condition allowed by the air conditioner.
After the noise residual value signal is obtained, the noise residual value signal can be compared with a preset threshold value, if the noise residual value signal is identified not to exceed the preset threshold value, the fact that the original noise of the compressor is weakened by more secondary noise is indicated, and the noise residual value signal can meet the noise condition allowed by the air conditioner, the step S203 is executed; if the identified noise residual value signal exceeds the preset threshold value, which indicates that the original noise of the compressor is weakened by less secondary noise, so that the noise residual value signal fails to meet the noise condition allowed by the air conditioner, and the noise of the compressor needs to be further reduced, step S204 is executed. The preset threshold value can be set according to actual conditions.
And S203, controlling the sound generator to maintain the generation of the secondary noise.
And identifying that the noise residual value signal does not exceed the preset threshold value, which shows that the noise residual value signal can meet the noise condition allowed by the air conditioner, and at the moment, the noise of the compressor is not required to be further weakened, and the current secondary noise can be maintained to be generated.
And S204, controlling the sound generator to generate new secondary noise.
And identifying that the noise residual value signal exceeds a preset threshold value, which indicates that the noise residual value signal cannot meet the noise condition allowed by the air conditioner, and the noise of the compressor needs to be further weakened, controlling the sound generator to regenerate new secondary noise, and continuing to interfere with the noise of the compressor by using the new secondary noise.
Optionally, iteration processing may be performed according to the noise residual value signal to obtain a new noise reference signal, then a new noise generation instruction for the sound generator is generated according to the new noise reference signal, the updated noise generation instruction is input to the sound generator, so that the sound generator regenerates a new secondary noise according to the updated noise generation instruction, and a new noise residual value signal fed back after the interference of the secondary noise is obtained again until the newly-collected noise residual value signal meets the noise condition allowed by the air conditioner, and the iterative update is stopped.
Therefore, the secondary noise generated based on the noise reference signal in the application is closer to the secondary noise capable of completely weakening the noise of the compressor, the number of times of iterative processing according to the noise residual value signal can be effectively reduced, and the noise of the compressor can be reduced more quickly and effectively. Furthermore, when the compressor is powered on and operated next time, a more accurate new noise reference signal can be obtained according to the updated mapping relation, and the noise of the compressor can be reduced more quickly and effectively based on the new noise reference signal in the operation process of the compressor.
Optionally, after the iterative update is stopped, the current signal, the noise signal and the noise reference signal acquired in the noise reduction process may be used to update the mapping relationship between the current signal, the noise signal and the noise reference signal, and the mapping relationship is stored in the memory, for example, the mapping relationship obtained in the last operation process of the compressor may be covered. After the compressor is powered on again, after the current signal and the noise signal are acquired, the updated mapping relation can be read from the memory to be used as a basis for acquiring the noise reference signal in the operation process.
The technical scheme in the embodiment of the application at least has the following technical effects or advantages:
according to the method and the device, the noise residual value signal can be acquired after the secondary noise interferes with the original noise of the compressor, so that whether the noise residual value signal meets the allowable noise condition or not can be identified, and after the noise residual value signal does not meet the allowable noise condition, the sound generator can be controlled to regenerate new secondary noise so as to reduce the noise of the compressor until the noise residual value signal meets the allowable noise condition, and a good noise reduction effect is ensured. Optionally, after the noise residual value signal meeting the allowable noise condition is obtained through the iterative algorithm, the mapping relationship between the current signal and the noise reference signal can be updated, when the compressor is powered on for the next time, a more accurate new noise reference signal can be obtained according to the updated mapping relationship, and in the operation process of the compressor, the noise of the compressor can be reduced more conveniently and effectively based on the new noise reference signal.
Fig. 4 is a schematic flow chart of a noise reduction method of an air conditioner according to another embodiment of the present application, and as shown in fig. 4, the method specifically includes the following steps:
s301, acquiring a current signal of a compressor in the air conditioner.
S302, collecting a current noise signal of a compressor in the air conditioner.
And S303, acquiring a noise reference signal according to the current signal and the noise signal.
S304, controlling the sound generator to generate secondary noise according to the noise reference signal; wherein the secondary noise interferes with the primary noise of the compressor to reduce the noise of the compressor.
S305, collecting a noise residual value signal after the secondary noise interferes with the original noise of the compressor.
S306, judging whether the noise residual value signal meets the noise condition allowed by the air conditioner.
And S307, controlling the sound generator to maintain the generation of the secondary noise.
And S308, controlling the sound generator to generate new secondary noise.
The technical scheme in the embodiment of the application at least has the following technical effects or advantages:
1. the noise reference signal can be obtained based on the obtained current signal and the obtained noise signal, and then secondary noise which can interfere with the original noise of the compressor is actively generated according to the noise reference signal so as to reduce the noise of the compressor. In addition, the secondary noise can be dynamically updated along with different original noise signals of the compressor, so that a better noise reduction effect can be obtained under any working condition or any compressor operation frequency, and the problems of poor applicability and non-ideal noise reduction effect are fundamentally solved.
