Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present application, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type, and are not limited to the number of objects, such as the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The following describes in detail the operation principle of the air conditioner according to the embodiment of the present application:
as shown in fig. 1, the compressor compresses a refrigerant (refrigerant), and sends the compressed refrigerant to the condenser through a pipe, and the high-temperature and high-pressure gaseous refrigerant releases heat in the condenser to change the gaseous refrigerant into a medium-temperature and high-pressure liquid refrigerant. After that, the medium-temperature and high-pressure liquid refrigerant is reduced in pressure by a capillary tube (throttle unit) and becomes a low-temperature and low-pressure liquid refrigerant. The low temperature and low pressure liquid refrigerant is delivered to the evaporator where it evaporates from a liquid to a gas and absorbs a large amount of heat during the evaporation process. Finally, the low-temperature low-pressure gaseous refrigerant in the evaporator is delivered to the compressor to participate in the next cycle. When the air conditioner is used for refrigerating, the heat exchanger of the outdoor unit is a condenser, and the heat exchanger of the indoor unit is an evaporator, otherwise, when the air conditioner is used for heating, the heat exchanger of the outdoor unit is an evaporator, and the heat exchanger of the indoor unit is a condenser.
The following description is made with respect to terms related to embodiments of the present application:
Millimeter wave radar is a novel wireless communication technology which is rapidly developed in recent years, and has wide application in human body detection. The millimeter wave radar technology is to utilize the tiny change of a weak signal to extract the related information of a target object by transmitting a millimeter wave signal to the target object and receiving an echo signal thereof, so as to realize the non-contact and non-invasive measurement and identification of the object.
Based on the above characteristics of millimeter wave radar, its application in human body detection includes the following aspects:
Health monitoring, namely detecting physiological parameters such as heart beat, respiration, body temperature and the like of a human body, and is used for health monitoring and disease prevention. For example, in the medical field, the heart or respiratory power of a patient may be monitored by millimeter wave radar, which may allow a physician to more accurately understand the health of the patient. Gesture recognition, namely, by detecting and recognizing the human body gesture, the method can be further applied to the fields of human body movement analysis, posture correction and the like, and is helpful for the physical health and movement effect of people. For example, in gyms, millimeter wave radar may be used to detect whether an athlete's stance is accurate, in order to correct the athlete's wrong stance and reduce injury to the sport. The millimeter wave radar can perform security check on human bodies, identify and detect dangerous goods, thermal energy substances and the like, and timely find personnel carrying dangerous goods in airports, large public places and the like, thereby ensuring safety. In addition, when the human body condition is detected to be bad, the millimeter wave radar can automatically send a signal to emergency personnel so as to obtain emergency assistance. In a word, millimeter wave radar has many applications in human body detection, can effectively promote people's quality of life and ensure human safety. Future applications will also be more extensive and diverse due to the development of millimeter wave radar technology.
Compared with the traditional infrared sensor, the millimeter wave radar has the following advantages:
Compared with the infrared sensing triggering, the method reduces the false touch rate and breaks the limitation of mobile monitoring. The millimeter wave radar can realize target personnel presence sensing, track tracking, personnel counting and the like in the office scene area range. Compared with a camera, the millimeter wave radar does not involve privacy disclosure, and meets the requirements of related privacy regulations. The camera is more suitable for office scenes such as staff office areas, conference spaces, open spaces, even highly sensitive places such as toilets and rest areas, which are inconvenient to deploy cameras. Compared with infrared sensing equipment which relies on transparent materials such as glass and plastic and the like as a shell, the ultrasonic equipment needs to avoid a short plate of a shielding object when in use, and the limiting factors of the millimeter wave radar are much less, so that the infrared sensing equipment does not need to have specific shape setting like an infrared sensor or be arranged at a place with wide visual angle like an intelligent camera, and can be integrated into different equipment to serve as basic hardware.
As can be seen from the above, since the compressor is provided in the outdoor unit, the outdoor unit inevitably generates a large noise when the air conditioner is operated in the cooling or heating mode, and particularly, many households in summer may be subjected to window opening ventilation.
In view of the above technical problems in the related art, an embodiment of the present application provides a control method for reducing the noise influence of an outdoor unit of an air conditioner, where other people affected by the noise of the outdoor unit of the air conditioner can inform the air conditioner that the noise generated by the outdoor unit of the influence has been caused by the specific gesture, so that the air conditioner can reduce the noise of the outdoor unit by reducing the fan rotation speed of the outdoor unit and reducing noise reduction measures such as the running frequency of a compressor.
The control method for reducing the noise influence of the outdoor unit of the air conditioner provided by the embodiment of the application is described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.
As shown in fig. 2, a control method for reducing noise influence of an outdoor unit of an air conditioner according to an embodiment of the present application may include the following steps 201 and 202:
step 201, monitoring limb actions of a target area in an outdoor area based on millimeter wave radar arranged on the outdoor unit.
The millimeter wave radar is disposed on an outdoor unit of an air conditioner to monitor limb movements of all objects in a target area. The target area may be an area within a predetermined range centered on the outdoor unit.
For example, the other persons in the target area are affected by the outdoor noise to a high degree, and the other persons outside the target area are affected by the outdoor noise to a low degree. The size of the target area may be set in advance or may be set according to the recognition distance of the millimeter wave radar. I.e., the farther the millimeter wave radar is identified, the greater the range of the target area.
The target trigger motion may be any gesture motion, such as a cross-hand motion, a forward palm motion, for example.
Step 202, controlling the outdoor unit to execute a noise reduction operation when the limb action of any target object in the target area is determined to be a target trigger action.
The noise reduction operation comprises at least one of reducing the rotating speed of a fan of the outdoor unit and reducing the running frequency of a compressor.
For example, when it is recognized that the limb motion of any one target object exists in the target area as the target trigger motion, the noise of the outdoor unit has a large influence on the target object, and at this time, the influence on the target object can be reduced by controlling the outdoor unit to perform the noise reduction operation.
It should be noted that, in order to facilitate that other people can know that a specific action can trigger the outdoor unit to perform the noise reduction operation, operation guiding information can be posted on the outdoor unit, so that other people can know what limb action can trigger the outdoor unit to perform the noise reduction operation.
In one possible implementation, the strength of the noise reduction operation may be determined according to the distance between the target object and the outdoor unit.
Specifically, the step 202 may further include the following steps 202a1 and 202a3:
Step 202a1, determining a target distance between the target object and the outdoor unit when the limb motion of any target object in the target area is determined as a target trigger motion.
Step 202a2, determining a first adjustment ratio of the fan rotation speed of the outdoor unit and/or a second adjustment ratio of the compressor operation frequency according to the target distance.
Step 202a3, reducing the fan rotation speed of the outdoor unit according to the first adjustment ratio, and/or reducing the compressor operation frequency according to the second adjustment ratio.
The first adjustment proportion is inversely related to the target distance, and the second adjustment proportion is inversely related to the target distance.
It is understood that the farther the distance between the target object and the outdoor unit is, the smaller the influence of the noise of the outdoor unit is, and the smaller the force of the noise reduction operation of the outdoor unit is when the noise reduction operation is performed. On the contrary, the closer the distance between the target object and the outdoor unit is, the more the influence of the noise of the outdoor unit is, and the more the noise reduction operation of the outdoor unit is performed.
In another possible implementation manner, the target object may express the severity of the influence of noise by different limb movements, and the outdoor unit may trigger the noise reduction operation with different forces according to the different limb movements.
Specifically, the target trigger actions include a first trigger action, a second trigger action, and a third trigger action, and the step 202 may further include any one of the following steps 202b1 to 202b 3:
step 202b1, when the limb movement of the target object is determined to be the first trigger movement, reducing the fan rotation speed of the outdoor unit and/or the compressor operation frequency according to a first adjustment parameter.
Step 202b2, when the limb movement of the target object is determined to be the second trigger movement, reducing the fan rotation speed of the outdoor unit and/or the compressor operation frequency according to a second adjustment parameter.
Step 202b3, when the limb movement of the target object is determined to be the third trigger movement, reducing the fan rotation speed of the outdoor unit and/or the compressor operation frequency according to a third adjustment parameter.
The first adjusting parameter is larger than the second adjusting parameter in adjusting the fan rotating speed of the outdoor unit and the compressor operating frequency, and the second adjusting parameter is larger than the third adjusting parameter in adjusting the fan rotating speed of the outdoor unit and the compressor operating frequency.
The first trigger action, the second trigger action, and the third trigger action are different trigger actions, and the different trigger actions can trigger the outdoor unit to execute noise reduction operations with different forces. For example, the first trigger operation may be an arm cross operation, the second trigger operation may be a parallel operation of the arms in the vertical direction, and the third trigger operation may be a parallel operation of the arms in the horizontal direction.
In the embodiment of the application, the noise reduction operation is divided into three gears of high, medium and low, and different limb actions can trigger different noise reduction operations. Those skilled in the art can expand a plurality of gears on the basis of the above, and the method belongs to the protection scope of the embodiment of the application.
Optionally, in the embodiment of the present application, because the imaging definition of the millimeter wave radar directly affects the accuracy of the limb motion recognition, and the outdoor unit generates stronger vibration during operation, in order to improve the accuracy of the millimeter wave radar in limb motion recognition, the influence of the outdoor unit vibration on the millimeter wave radar needs to be reduced.
It can be appreciated that the air conditioner can generate vibration when running, and the vibration can influence the imaging definition of the millimeter wave radar arranged on the air conditioner, so that the running of the air conditioner is influenced, for example, the vibration can influence the judgment of the limb action of a user, so that the identification accuracy of the action is reduced, and the function based on the limb action identification is difficult to trigger.
Illustratively, as shown in FIG. 3, an embodiment of the present application provides a vibration canceling device that includes a vibration sensor, a millimeter wave radar (other radars are possible), and a vibration generator. The vibration eliminating device is arranged on the outdoor unit, the millimeter wave radar is arranged on the vibration eliminating device, and the millimeter wave radar is not in direct contact with the outdoor unit.
Illustratively, based on the vibration canceling device shown in fig. 3, vibration information of the outdoor unit may be detected, and a vibration signal capable of canceling the vibration of the outdoor unit may be generated, so as to reduce the influence of the vibration of the outdoor unit on the imaging of the millimeter wave radar, and improve the imaging definition of the millimeter wave radar provided on the outdoor unit.
As shown in fig. 4, before the step 202, the control method for reducing the noise influence of the outdoor unit of the air conditioner according to the embodiment of the present application may further include the following steps 401 to 403:
Step 401, acquiring a first vibration signal of an outdoor unit when the outdoor unit is running.
The first vibration signal comprises vibration information of multiple times of vibration of the outdoor unit.
Specifically, the first vibration signal of the outdoor unit may be obtained by the following steps, that is, the above step 401, may include the following steps 401a1 and 401a2:
Step 401a1, obtaining vibration information of the outdoor unit.
The vibration information includes, for example, a vibration amplitude of each vibration, and a vibration period of each vibration.
Step 401a2, when the vibration information indicates that the vibration amplitude of the outdoor unit is greater than a preset amplitude, and/or the vibration frequency of the outdoor unit is greater than a preset frequency, performing vibration sampling on the outdoor unit by using the vibration sensor, so as to obtain the first vibration signal.
For example, the minute vibration generated from the outdoor unit does not affect the imaging of the millimeter wave radar, and thus, the outdoor unit may perform the vibration canceling operation in the case where the vibration amplitude of the outdoor unit is greater than the preset amplitude and/or the vibration frequency of the outdoor unit is greater than the preset frequency.
It should be noted that, the vibration waveform of the outdoor unit is similar to the simple harmonic, but the time consumed by each vibration (the vibration period is different) of the outdoor unit is not exactly the same, and the vibration amplitude of each vibration is not exactly the same, so in order to cancel the influence of the vibration of the outdoor unit on the millimeter wave radar imaging, it is necessary to collect vibration information generated by multiple times of vibration, and calculate the average vibration amplitude and the average vibration period, so as to generate an anti-phase vibration wave opposite to the vibration wave of the outdoor unit based on the average vibration amplitude and the average vibration period, and further cancel the vibration generated by the outdoor unit.
Step 402, calculating an average value of a plurality of vibration amplitudes included in the first vibration signal and an average value of a plurality of vibration periods included in the first vibration signal according to the first vibration signal, obtaining an average vibration amplitude and an average vibration period, and generating a second vibration signal based on the average vibration amplitude and the average vibration period.
The average vibration amplitude and the average vibration period are each obtained by averaging the vibration amplitude and the vibration period included in the vibration information of the plurality of vibrations acquired in the above step, for example.
Specifically, in the step 402, an average value of a plurality of vibration amplitudes included in the first vibration signal and an average value of a plurality of vibration periods included in the first vibration signal are calculated according to the first vibration signal, so as to obtain an average vibration amplitude and an average vibration period, which may include the following steps 402a and 402b:
step 402a, determining a vibration period of each vibration and a vibration amplitude of each vibration in vibration information of a plurality of vibrations included in the first vibration signal.
Step 402b, calculating the average vibration period according to the vibration period of each vibration, and calculating the average vibration amplitude according to the vibration amplitude of each vibration.
As shown in fig. 5, for example, a waveform diagram of the vibration wave generated when the outdoor unit is operated is shown, and according to the waveform diagram, the amplitude of the vibration wave generated when the outdoor unit is operated is not exactly the same for each period, and there is a certain difference. Therefore, in order to facilitate calculation of the anti-phase vibration wave, the average vibration amplitude and the average vibration period of the plurality of vibrations can be calculated, and further the anti-phase vibration wave can be obtained from the average vibration amplitude and the average vibration period.
Specifically, the step 402a may include the following step 402a1:
Step 402a1, calculating the average vibration period T according to the following formula:
Wherein n is the vibration sampling frequency, and T i is the vibration period of each vibration.
For example, in calculating the average vibration period, the average vibration period may be calculated by directly adding up n vibration periods obtained by sampling n times of vibration.
Specifically, the step 402b may include the following step 402b1:
step 402b1, calculating the average vibration amplitude A according to the following formula
Wherein n is the vibration sampling times, A i is the displacement extreme value of each vibration, and one vibration comprises the displacement at the wave crest and the displacement at the wave trough.
For example, in calculating the average vibration amplitude, in order to make the average vibration amplitude more approximate to the real situation, the average vibration amplitude may be obtained by averaging the sum of squares of 2n vibration amplitudes obtained by sampling n times of vibration.
It will be appreciated that each vibration includes a maximum positive offset and a maximum negative offset, and that squaring a i is required to eliminate the effect of positive and negative values.
For example, after the average vibration amplitude and the average vibration period are obtained, waveform fitting may be performed based on the average vibration amplitude and the average vibration period to obtain an antiphase vibration wave of the original waveform, that is, the second vibration signal.
Illustratively, in the embodiment of the present application, the above-described second vibration signal may be obtained by the following two ways.
Mode 1:
in embodiment 1, a sine wave may be fitted directly to the average vibration amplitude and the average vibration period, and the second vibration signal may be obtained based on the sine wave.
Specifically, the generating of the second vibration signal based on the average vibration amplitude and the average vibration period in the step 402 may include the following steps 402c1 and 402c2:
step 402c1, generating a sine wave fitting signal according to the average vibration amplitude and the average vibration period.
And step 402c2, shifting the sine wave fitting signal according to a target offset to obtain the second vibration signal.
The target offset is half of the average vibration period, the vibration amplitude of the second vibration signal is the average vibration amplitude, and the vibration period of the second vibration signal is the average vibration period.
Mode 2:
In mode 2, the number of samples of the original waveform (i.e., the first vibration signal) can be increased, and a waveform of the vibration wave closer to the indication of the first vibration signal can be fitted based on the average vibration amplitude and the average vibration period.
Specifically, the generating of the second vibration signal based on the average vibration amplitude and the average vibration period in the step 402 may include the following steps 402d1 and 402d2:
step 402d1, generating a vibration wave fitting signal according to the average vibration amplitude, the average vibration period and the average vibration median value.
And step 402d2, shifting the vibration wave fitting signal according to a target offset to obtain the second vibration signal.
The average vibration median value is an average value calculated based on a deviation value median value of each vibration, the target deviation value is half of the average vibration period, the vibration amplitude of the second vibration signal is the average vibration amplitude, and the vibration period of the second vibration signal is the average vibration period.
Illustratively, the average vibration median value B described above can be calculated by the following formula three:
Wherein n is the vibration sampling times, B is the displacement median value of each vibration, and one vibration comprises 4 displacement median values.
In order to cancel the vibration generated by the outdoor unit, the wave trough of the second vibration signal needs to correspond to the wave crest of the first vibration signal, and the wave crest of the second vibration signal needs to correspond to the wave trough of the first vibration signal.
And step 403, controlling a vibration generator arranged on the vibration eliminating device to vibrate based on the second vibration signal so as to reduce the influence of the vibration of the outdoor unit on millimeter wave radar imaging.
The vibration eliminating device is arranged on the outdoor unit, the millimeter wave radar is arranged on the vibration eliminating device, and the millimeter wave radar is not in direct contact with the outdoor unit. That is, the millimeter wave radar is installed on the outdoor unit through the vibration canceling device.
The millimeter wave radar described above may also be replaced by a laser radar, a Time of flight (TOF) camera, an infrared sensing device, or an RGB camera, for example.
Illustratively, by controlling the vibration generator to generate the anti-phase vibration wave (i.e., the above-described second vibration signal) as shown in fig. 6, the anti-phase vibration wave can be cancelled out with the original vibration wave (i.e., the above-described first vibration signal) generated by the outdoor unit, and the amplitude of the cancelled vibration wave is small, as shown in fig. 6, so that it is difficult to influence the imaging of the millimeter wave radar.
Alternatively, in the embodiment of the present application, in order to cancel out the vibration wave generated by the outdoor unit by the anti-phase vibration wave generated by the vibration generator, it is necessary to ensure that the vibration direction of the vibration generator is consistent with the vibration direction of the outdoor unit.
The vibration generator is provided with a linear motor, and the vibration generator is also provided with a rotating mechanism for adjusting the angle of the linear motor. The step 403 may further include the following steps 403a1 and 403a2:
step 403a1, determining a vibration direction of the outdoor unit according to the vibration signal of the outdoor unit, determining a rotation angle and a rotation direction of the rotation mechanism according to the vibration direction of the outdoor unit, and determining a voltage value and a frequency value of the input voltage of the linear motor according to the vibration amplitude and the vibration period of the second vibration signal.
Step 403a2, controlling the rotation of the rotation mechanism according to the rotation angle and the rotation direction of the rotation mechanism, and controlling the operation of the linear motor according to the voltage value and the frequency value of the input voltage.
Wherein, the rotary mechanism is used for keeping the vibration direction of the linear motor consistent with the vibration direction of the outdoor unit.
The rotation mechanism may rotate in any direction to ensure that any vibration generated by the outdoor unit is counteracted by the vibration canceling device.
