Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 1, in an embodiment of the present application, an air conditioner 1 is provided, where the air conditioner 1 is configured to be installed in a designated area and provide an air conditioning effect to the designated area, so as to improve air quality of the designated area and improve comfort of a user. The air conditioner 1 includes a compressor 3, and the compressor 3 is configured to compress and guide out a refrigerant, and simultaneously provide power for the refrigerant to circulate in the air conditioner 1, so that the air conditioner 1 can conveniently perform air conditioning on a designated area under the condition that the refrigerant circulates in the air conditioner 1.
Since the compressor 3 may vibrate during operation and the vibration of the compressor 3 may be intensified as the operation frequency of the compressor 3 increases, noise may be generated when the vibration of the compressor 3 reaches a certain degree, thereby reducing the user experience. Therefore, in the prior art, when the air conditioner 1 product is generally developed, the air conditioner 1 is subjected to a noise test in a laboratory, the frequency point of the compressor 3 with the noise exceeding the standard caused by wall resonance is selectively shielded, and the tested frequency point of the compressor 3 is written into a controller of the air conditioner 1, so that the compressor 3 can operate by shielding the frequency point under the condition of controlling the operation of the compressor 3, and the purpose of removing the noise can be realized. However, the above method is only suitable for laboratory test conditions, and cannot meet the actual use environment of all users, which has great limitations.
In order to solve the technical problem that the noise removal control limitation of the air conditioner 1 is large due to different use environments in the prior art, the air conditioner 1 is provided. The air conditioner 1 includes a memory 4, and a first storage area and a second storage area are preset in the memory 4, the first storage area is configured to store a plurality of noise masking values, and the second storage area is configured to store a plurality of frequency masking values. Under the condition that the air conditioner 1 reads the multiple noise shielding values in the first storage area and the multiple frequency shielding values in the second storage area in the memory 4, the compressor 3 of the air conditioner 1 can shield the multiple frequency shielding values to operate, in other words, the compressor 3 operates at an operating frequency other than the multiple operating frequencies corresponding to the multiple frequency shielding values, so that multiple noises corresponding to the multiple noise shielding values cannot occur in the operation process of the air conditioner 1, and the use experience of a user is improved. It should be noted that, in some embodiments of the present application, the Memory 4 in the air conditioner 1 is an electrically Erasable Programmable Read-Only Memory 4 (EEPROM), so that a plurality of noise mask values stored in the first storage area and a plurality of frequency mask values stored in the second storage area in the Memory 4 can be automatically updated, in other words, the data stored in the Memory 4 can be updated in real time according to the actual environment of the user, so that the denoising method operated by the air conditioner 1 can be adapted to the actual environment of the user, and the technical problem of the prior art that the limitation of denoising control of the air conditioner 1 is large due to different environments is solved.
Of course, the air conditioner 1 may further include a processor, and when the noise mask value in the first storage area and the frequency mask value in the second storage area are read by the processor, the operation of the compressor 3 may be controlled for the purpose of noise removal and the air conditioner 1 may be caused to operate the automatic noise removal control method provided hereinafter.
Optionally, in some embodiments of the present application, the air conditioner 1 further comprises a noise detection device 5 and a compressor frequency detection device 6. Wherein, the noise detection device 5 is disposed on the air conditioner 1 to detect the noise value of the air conditioner 1 in the operation state. A compressor frequency detection device 6 is provided on the air conditioner 1, and the compressor frequency detection device 6 is configured to detect an operating frequency value of the compressor 3.
Of course, the air conditioner 1 may further include a main control module 2, the main control module 2 is electrically connected to the memory 4, and the main control module 2 is configured to read a plurality of noise masking values in the first storage area and a plurality of frequency masking values in the second storage area in the memory 4, so that the air conditioner 1 may be controlled to shield the plurality of frequency masking values for operation, so as to prevent noise corresponding to the plurality of noise masking values. In addition, the main control module 2 is electrically connected with the noise detection device 5 and the compressor frequency detection device 6, so that the main control module 2 can obtain a noise value and an operation frequency value. In addition, the main control module 2 may further write the noise value and the operating frequency value into the first storage area and the second storage area respectively when the noise value meets the preset noise removing condition, so as to update the data in the first storage area and update the data in the second storage area, so that the main control module 2 may control the operation of the compressor 3 according to the updated plurality of frequency mask values to shield the corresponding operating frequency under the condition that the main control module 2 reads the data in the first storage area and the second storage area to control the air conditioner 1, thereby preventing the air conditioner 1 from generating a plurality of noises corresponding to the updated plurality of noise mask values. Therefore, the air conditioner 1 can automatically adapt to the actual environment of the air conditioner 1, the technical problem that the air conditioner 1 is large in limitation of noise removal control due to different use environments in the prior art is solved, and good use experience of a user is guaranteed.
Based on the air conditioner 1 provided above, the embodiment of the present application further provides an automatic denoising control method, which is used to solve the technical problem in the prior art that the denoising control of the air conditioner 1 is limited greatly due to different use environments. Referring to fig. 2, the automatic denoising control method includes:
and step S10, acquiring the running frequency value of the compressor 3 under the condition that the received noise value meets the preset denoising condition.
In the case that the noise detection device 5 sends the detected noise value to the main control module 2, the main control module 2 may be configured to determine whether the noise value satisfies a preset noise cancellation condition. In the case that the noise value satisfies the preset noise removing condition, it indicates that the noise value has reached the condition requiring noise removal, and therefore, the main control module 2 may obtain the operating frequency value of the compressor 3 corresponding to the noise value.
Optionally, before step S10, the automatic denoising control method further includes:
and S02, receiving the noise value.
The noise value is automatically detected by the noise detection device 5, and after the noise value is detected by the noise detection device 5, the noise value is sent to the main control module 2, and the main control module 2 obtains the noise value.
In addition, referring to fig. 3, step S10 may include:
and step S111, if the noise value is larger than the preset noise value, judging whether the noise value is larger than all the noise shielding values in the first storage area.
It should be noted that, the preset noise value is a threshold considered to be set, and in a case where the noise value reaches the threshold, it indicates that the noise value may form noise to affect the user. Therefore, when the noise value is larger than the preset noise value, the noise value is compared with the plurality of noise mask values in the first storage area to determine whether the noise value has been stored in the first storage area, and whether the noise value has a larger influence than the plurality of noise mask values is determined.
And step S112, if the noise value is larger than the total noise shielding value, judging that the noise value meets the preset denoising condition.
When the noise value is greater than the total noise mask value, it indicates that the noise value has a greater influence on the user than the noise corresponding to the total noise mask value, and therefore, it indicates that the noise value satisfies the noise removal condition and it is necessary to remove the noise generated by the noise value. Therefore, if the determination result in step S111 is yes, it indicates that the noise value satisfies the preset noise cancellation condition.
Of course, in other embodiments of the present application, other determination manners may be adopted for determining whether the noise value satisfies the predetermined denoising condition, for example, after step S111, if the noise value is greater than one of the noise masking values, it is determined that the noise value satisfies the predetermined denoising condition, and the like.
Optionally, referring to fig. 4, in an embodiment of the present application, step S10 may further include:
step S121, if the noise value is obtained according to the noise removal instruction set by the user, determining that the noise value satisfies the preset noise removal condition.
It should be noted that the denoising instruction may be sent by a user through a remote controller adapted to the air conditioner 1, in other words, when the user considers that the current noise has affected the user, the user may send the denoising instruction to the air conditioner 1 through the remote controller, and obtain the current noise value under the condition that the main control module 2 receives the denoising instruction, where the noise value meets the preset denoising condition. Of course, the denoising instruction may also be sent by the user through another intelligent terminal, and the intelligent terminal may be a mobile phone, a computer, or another intelligent device. The noise canceling command may be made by a voice or a gesture made by the user, for example, the air conditioner 1 may be provided with a voice recognition device and a gesture recognition device, and when the user makes a corresponding voice or gesture, the voice recognition device may be triggered or the gesture recognition device may be triggered to issue the noise canceling command.
In addition, when the main control module 2 receives the noise canceling instruction, the main control module 2 acquires a noise value detected and emitted by the noise detection device 5. The noise detection device 5 may detect the noise value in real time, and send the noise value to the main control module 2, and when the main control module 2 receives the noise removal instruction, it indicates that the currently obtained noise value meets the preset noise removal condition, and at the same time, obtains the operating frequency value of the compressor 3 corresponding to the noise value.
Optionally, in some embodiments of the present application, the first storage area includes a first automatic storage area and a first mandatory storage area. The first automatic storage area and the first forced storage area each store therein a plurality of noise mask values. In addition, the second storage area includes a second automatic storage area and a second forced storage area, and a plurality of frequency mask values are stored in both the second automatic storage area and the second forced storage area. It should be noted that the first automatic storage area and the second automatic storage area are configured to store the noise value and the operating frequency value that need to be updated after step S111 and step S112, and the first forced storage area and the second forced storage area are configured to store the noise value and the operating frequency value that need to be updated after step S121; in other words, under the condition that the main control module 2 automatically judges that the noise value meets the preset denoising condition, the noise value and the operation frequency value can be respectively stored in the first automatic storage area and the second automatic storage area; under the condition that the main control module 2 judges that the noise value is obtained according to the noise removing instruction, the noise value and the operation frequency value can be respectively stored in the first forced storage area and the second forced storage area. Of course, in other embodiments of the present application, the first automatic storage area and the second automatic storage area may be the same storage area, and the first forced storage area and the second forced storage area may be the same storage area.
Optionally, in some embodiments of the present application, the number of noise mask values allowed to be stored in the first automatic storage area is greater than the number of frequency mask values allowed to be stored in the first mandatory storage area, and similarly, the number of noise mask values allowed to be stored in the second automatic storage area is greater than the number of frequency mask values allowed to be stored in the second mandatory storage area; and, the number of noise mask values allowed to be stored in the first automatic storage area is equal to the number of frequency mask values allowed to be stored in the second automatic storage area, and the plurality of noise mask values stored in the first automatic storage area correspond to the plurality of frequency mask values stored in the second automatic storage area, respectively, wherein the noise mask values correspond to the frequency mask values to indicate that, in a corresponding actual environment, in a case where the air conditioner 1 controls the operation of the compressor 3 by the frequency mask values, the air conditioner 1 generates noise corresponding to the noise mask values; similarly, the number of noise mask values allowed to be stored in the first forced storage area is equal to the number of frequency mask values allowed to be stored in the second forced storage area; and, the plurality of noise mask values stored in the first forced storage area correspond to the plurality of frequency mask values stored in the second forced storage area, respectively.
After the noise value obtained by the main control module 2 in step S10 satisfies the preset noise removing condition and the main control module 2 obtains the operating frequency value corresponding to the noise value, please refer to fig. 2, where the method for controlling automatic noise removing further includes:
step S20, updating at least one noise mask value in the first storage area with the noise value.
In other words, when the main control module 2 determines that the received noise value satisfies the preset denoising condition, it indicates that the noise corresponding to the currently received noise value affects the user, and thus the noise corresponding to the noise value needs to be denoised. Accordingly, at least one noise mask value in the first storage area is updated with the noise value.
It should be noted that the noise value updates at least one noise mask value in the first storage area to indicate: and writing the data corresponding to the noise value into a first automatic storage area or a first forced storage area in the first storage area, wherein an upper limit exists in the data storage based on the first storage area, so that the data corresponding to the noise value replaces the data corresponding to at least one noise shielding value, and the data in the first storage area is updated.
Wherein, after step S111 and step S112, step S20 can be expressed as: at least one noise mask value in the first automatic storage area is updated with the noise value. Of course, after step S121, step S20 may be expressed as: at least one noise mask value in the first forced storage area is updated with the noise value.
Optionally, referring to fig. 5, in some embodiments of the present application, step S20 may include:
step S21, the minimum noise mask value in the first storage area is updated with the noise value.
In other words, the noise value may be updated in step S20 by replacing the data corresponding to the smallest noise mask value in the plurality of noise mask values with the data corresponding to the current noise value, so that the air conditioner 1 can preferentially mask the larger noise when reading the noise mask value in the first storage area, so as to improve the user experience.
Of course, in some embodiments of the present application, if the noise masking values in the first storage area are equal, in other words, if the noise magnitudes corresponding to the noise masking values in the first storage area are equal, the step S20 may further include:
step S22, the noise mask value with the longest storage time is updated by the noise value.
By updating the noise mask value with the longest storage time in the first storage area, the distortion problem caused by overlong data storage time can be prevented, and therefore the automatic denoising control method can be ensured to accurately perform denoising control.
The automatic denoising control method further comprises the following steps:
step S30, updating at least one frequency mask value in the second memory area with the running frequency value.
In other words, under the condition that the main control module 2 determines that the received noise value meets the preset noise removing condition, it indicates that the current operating frequency of the compressor 3 causes a large noise, so as to affect the user, and therefore, the operating frequency value of the compressor 3 corresponding to the noise value is recorded, so that the main control module 2 can shield the corresponding operating frequency under the condition of controlling the operation of the compressor 3, thereby preventing the noise corresponding to the noise value from being caused, and achieving the purpose of removing the noise.
It should be noted that the update of the running frequency value in the second storage area indicates that at least one frequency mask value is: and writing the data corresponding to the operating frequency value into a second automatic storage area or a second forced storage area in the second storage area, wherein an upper limit exists in the second storage area based on the data storage in the second storage area, so that the data corresponding to the operating frequency value replaces the data corresponding to at least one frequency mask value, and the data in the second storage area is updated.
With continuing reference to fig. 2, after step S111 and step S112, step S30 can be represented as: updating at least one frequency mask value in the second automatic storage area with the running frequency value. Of course, after step S121, step S30 may be expressed as: at least one frequency mask value in the second pre-storage area is updated with the running frequency value.
Optionally, referring to fig. 6, in some embodiments of the present application, step S30 may include:
and step S31, updating the minimum frequency mask value in the second storage area by the running frequency value.
In other words, the operation frequency value may be updated in step S30 by replacing the data corresponding to the current operation frequency value with the data corresponding to the minimum frequency mask value in the plurality of frequency mask values, so that the air conditioner 1 can preferentially mask the larger operation frequency when reading the frequency mask value in the second storage area, thereby preventing the larger noise from being generated and improving the user experience.
Of course, in other embodiments of the present application, if the plurality of frequency mask values in the second storage area are equal, in other words, if the operating frequencies corresponding to the plurality of frequency mask values in the second storage area are equal, the step S30 may further include:
and step S32, updating the frequency mask value with the longest storage time by using the running frequency value.
By updating the frequency mask value with the longest storage time in the second storage area, the distortion problem caused by overlong data storage time can be prevented, and therefore the automatic denoising control method can be ensured to accurately perform denoising control.
With continued reference to fig. 2, after the data in the first storage area and the second storage area in the memory 4 are updated, the method for controlling automatic noise cancellation further includes:
