[0044] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0045] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0046] The main solution of the embodiment of the present application is: by responding to the detection of the target person, the initial distance corresponding to the current volume of the audio module is determined according to the current scene; the current position of the target person is detected by the ultrasonic sensor, and the current distance between the target person and the smart doorbell is determined based on the current position of the target person; the difference between the current distance and the initial distance is calculated to obtain the distance difference; the sound pressure level difference of the audio module is calculated based on the distance difference; the current volume of the smart doorbell is compensated based on the sound pressure level difference of the audio module. This solution uses a built-in ultrasonic sensor to identify the visitor position around the smart doorbell, and dynamically adjusts the volume of the audio modules such as the doorbell speaker (speaker), microphone, etc. by volume compensation in combination with the distance between the visitor position and the smart doorbell, so that the volume of the speaker and microphone of the smart doorbell can be intelligently adjusted in different scenes, ensuring that the visitor position changes always have a more appropriate volume effect, and further can adjust the sensitivity. This solution not only solves the shortcomings of infrared sensors in detecting visitor positions, but also solves the problem that the visitor position is not fixed and the voice call effect is poor, and can also improve the service life of the smart doorbell audio system; at the same time, it is conducive to the development of smart doorbells in the direction of intelligence and humanization.

[0047] Due to existing technology, most smart doorbells need to be equipped with infrared sensors to detect the visitor's location. This method of judging the visitor's location has a large error and a limited judgment distance. At the same time, it is impossible to intelligently adjust the volume based on the user's location. This affects the user experience and distance detection accuracy of smart products. Not only that, the speaker is under high load operation, and the product life and sound quality will deteriorate.

[0048] The present application provides a solution that can ensure that when the visitor's location changes, the smart doorbell always has a relatively appropriate volume effect, thereby improving the intelligence and humanization level of the smart doorbell, and / or its service life, and improving the user experience.

[0049] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a smart doorbell, etc. The following takes a smart doorbell as an example to illustrate this embodiment and the following embodiments.

[0050] Based on this, the embodiment of the present application provides a smart doorbell control method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the smart doorbell control method of the present application.

[0051] In this embodiment, the smart doorbell control method includes steps S10 to S50, each of which is explained in detail below.

[0052] like Figure 1 As shown, the first embodiment of the present application proposes a smart doorbell control method, wherein the smart doorbell is provided with an ultrasonic sensor and an audio module, and the method includes:

[0053] Step S10, in response to detecting the target person, determining an initial distance corresponding to the current volume of the audio module according to the current scene;

[0054] Among them, the target person can be a user such as a visitor of the smart home.

[0055] The audio module may include a speaker and / or a microphone of the smart doorbell. The speaker and the microphone may be installed on the camera of the smart doorbell.

[0056] The technical solution of this embodiment can compensate the volume of the camera's speaker and microphone according to the distance, so as to ensure that when the visitor's position changes, the smart doorbell always has a relatively appropriate volume effect, thereby improving the intelligence and humanization level of the smart doorbell, and / or its service life, and improving the user experience.

[0057] The executor of this embodiment may be a smart doorbell, which may be configured with a camera, an MCU chip, an amplifier module, a speaker, a microphone, an ultrasonic sensor, etc. The MCU chip is communicated with the camera, the amplifier module, the microphone, the ultrasonic sensor, etc., and each functional module is controlled by the MCU chip to perform its operation.

[0058] As an implementation method, when the volume of the speaker and microphone of the camera is adjusted for compensation according to the distance, a strategy of making the adjustment values ​​of the microphone and the speaker consistent can be adopted. This embodiment is mainly described using the speaker as an example.

[0059] In specific implementation, when a visitor comes, the target person, i.e. the visitor, can be detected by the camera of the smart doorbell. The camera sends the detection result to the MCU chip. In response to the detection of the target person, the MCU chip determines the initial distance corresponding to the current volume of the audio module according to the current scene.

[0060] The initial distance corresponding to the current volume of the audio module refers to the distance between the position corresponding to a default suitable volume of the audio module in the current scene and the smart doorbell.

[0061] The default suitable volume of the audio module can be preset according to the actual situation. For example, the audio module is a speaker. For example, the volume can be divided into different levels based on the preset volume change for different locations far away from the smart doorbell according to the playback volume of the speaker, such as 1, 2, 3... That is, different locations (or distances) can correspond to different default volumes.

[0062] In a possible implementation manner, different default volumes corresponding to the speaker and the microphone at different positions (or distances) may also be set in combination with changes in the sound pressure levels of the speaker and the microphone.

[0063] For example, the preset volume change of 10cm is the sound pressure level change ε ​​at the speaker position. Similarly, the microphone volume changes by 10cm and the sound pressure level changes θ after recording. The volume can be divided into 1, 2, 3...

[0064] Step S20, detecting the current position of the target person by an ultrasonic sensor;

[0065] Among them, the current location of the target person can be represented by the distance between the target person and the smart doorbell.

[0066] In this embodiment, an ultrasonic sensor is configured in the smart doorbell, and the current position of the target person (i.e., the visitor) is detected by the ultrasonic sensor so as to determine whether to adjust the volume of the speaker and the microphone according to the current position of the target person.

[0067] Among them, the ultrasonic sensor is a sensor that uses the characteristics of ultrasound to convert ultrasonic signals into electrical signals.

[0068] According to their working principles, ultrasonic sensors can be divided into piezoelectric, magnetostrictive, electromagnetic, etc. They are widely used in industry, national defense, biomedicine, etc., such as anti-theft alarms, lighting, automatic door switches, automobile anti-collision ranging, etc.

[0069] The working principle of ultrasonic sensors to detect the position of people is mainly based on ToF (Time-of-Flight) technology. This sensor transmits ultrasonic pulses and measures the time from the emission to the reflection of the target object, thereby calculating the distance between the target object and the sensor. The specific steps are as follows:

[0070] Transmit phase: The sensor transmits an ultrasonic pulse through the transmitter.

[0071] Receiving stage: The ultrasonic pulse propagates in the air and is reflected back after encountering the target object. The sensor's receiver receives the reflected ultrasonic signal.

[0072] Measurement phase: The sensor calculates the distance between the target object and the sensor by measuring the time difference between the transmission and reception of the ultrasonic pulse. Since the propagation speed of ultrasonic waves in the air is known, the distance can be calculated based on the relationship between the flight time and the propagation speed.

[0073] Ultrasonic sensors have the advantages of high precision, high measurement speed, and strong anti-interference ability, and are suitable for various environments and application scenarios. For example, in smart homes, they can be used for human detection, gesture recognition, and indoor positioning; in security monitoring, they can be used for intrusion detection, tracking, and deployment.

[0074] In addition, ultrasonic sensors also have the advantage of non-contact measurement, which will not damage the target object and is suitable for application scenarios that require non-contact with the measured object. They are relatively insensitive to external interference such as light and dust, and can maintain stable measurement performance in complex environments.

[0075] In terms of human behavior detection, ultrasonic sensors can detect the presence and movement of a human body by emitting ultrasonic waves and receiving the waves reflected by the human body. When a human body moves, the detected distance changes, thereby determining that someone is moving.

[0076] In general, ultrasonic sensors detect and measure the position of a person by emitting and receiving ultrasonic pulses and calculating the flight time of these pulses. They are widely used in many fields such as industrial automation, smart home, and security monitoring. In this embodiment, the current position of the target person (i.e., visitor) is detected by an ultrasonic sensor.

[0077] Compared with the prior art in which the smart doorbell is equipped with an infrared sensor to detect the visitor's location, which results in a large error in visitor location detection and a limited judgment distance, and at the same time, it is impossible to intelligently adjust the volume based on the user's location, which affects the user experience of the smart product and the distance detection accuracy. In this embodiment, an ultrasonic sensor is set in the smart doorbell to detect the visitor's location, which can greatly improve the accuracy of visitor location detection and the judgment distance is not limited.

[0078] Step S30, performing difference calculation based on the current position of the target person and the initial distance to obtain a distance difference;

[0079] Among them, in the specific implementation, as an implementation method, after the ultrasonic sensor detects the current position of the target person, it sends the current position of the target person to the MCU chip, and the MCU chip calculates the difference between the current position of the target person and the initial distance to obtain the distance difference.

[0080] Step S40, calculating the sound pressure level difference of the audio module based on the distance difference;

[0081] In one implementation, calculating the sound pressure level difference of the audio module based on the distance difference may include:

[0082] The sound pressure level difference of the audio module is calculated based on the distance difference and in combination with a preset sound pressure level difference calculation formula, wherein the sound pressure level difference calculation formula includes a correlation relationship between the sound pressure level and the distance.

[0083] Step S50, compensating the current volume of the smart doorbell based on the sound pressure level difference of the audio module.

[0084] In a feasible implementation manner, the step S50 of compensating the current volume of the smart doorbell based on the sound pressure level difference of the audio module may include steps A11 to A13:

[0085] A11, dividing the sound pressure level difference of the audio module by the sound pressure level change value corresponding to each preset distance of volume change to obtain a calculation result;

[0086] A12, determining a volume compensation value according to the calculation result;

[0087] Among them, different calculation results can correspond to different volume compensation values.

[0088] A13, compensate the current volume of the smart doorbell according to the volume compensation value.

[0089] In one embodiment, the volume compensation operation can be performed by the MCU chip and the power amplifier module of the smart doorbell. That is, the MCU chip can adjust the amplification factor of the power amplifier module according to the volume compensation value to compensate for the current volume of the smart doorbell.

[0090] Specifically, as an implementation method, taking a speaker as an example, the calculation and compensation principle of the sound pressure level difference of the speaker is as follows:

[0091] First, the appropriate volume distance A1 is determined for the default current volume of the speaker in the current scene. At this time, the sound pressure level of the speaker is SPL1; and through detection, the current distance A2 between the target person and the smart doorbell is determined. If the appropriate volume can be achieved by adjusting to the current distance, the sound pressure level of the speaker is SPL2.

[0092] Secondly, the difference between the two sound pressure levels is determined to obtain a sound pressure level difference value of the loudspeaker, so as to compensate the volume of the loudspeaker according to the sound pressure level difference value of the loudspeaker.

[0093] The sound pressure level difference calculation formula is as follows:

[0094] △SPL=SPL2-SPL1=20lg(A2 / A1).

[0095] The sound pressure level difference △SPL between the current distance A2 and the volume appropriate distance A1 is calculated according to the sound pressure level difference calculation formula △SPL=SPL2-SPL1=201g(A2 / A1).

[0096] Then, the volume compensation value is calculated based on the calculated sound pressure level difference △SPL, and the current volume of the speaker is compensated. The main calculation process is as follows:

[0097] The sound pressure level difference △SPL is divided by the sound pressure level change ε ​​corresponding to the volume change per 10cm to obtain the calculation result δ.

[0098] Among them, as a possible implementation, if -1<δ<1, the volume compensation value is 0; if -2<δ<-1, the volume compensation value is 1; if 1<δ<2, the volume compensation value is -1; if -3<δ<-2, the volume compensation value is 2; if 2<δ<3, the volume compensation value is -2; and so on. Other volume compensation values ​​can be calculated similarly.

[0099] Afterwards, the current volume of the smart doorbell can be compensated according to the volume compensation value.

[0100] Visitors can hear the normal volume of the voice played by the camera speaker. Similarly, the microphone pickup effect in the camera can also be compensated.

[0101] It can be understood that the technical solution of this embodiment, in response to the detection of the target person, determines the initial distance corresponding to the current volume of the audio module according to the current scene; detects the current position of the target person by an ultrasonic sensor; calculates the difference between the current position of the target person and the initial distance to obtain the distance difference; calculates the sound pressure level difference of the audio module based on the distance difference; and compensates the current volume of the smart doorbell based on the sound pressure level difference of the audio module. This solution uses a built-in ultrasonic sensor to identify the visitor position around the smart doorbell, and dynamically adjusts the volume of the audio modules such as the doorbell speaker (speaker), microphone, etc. by volume compensation in combination with the distance between the visitor position and the smart doorbell, so that the volume of the speaker and microphone of the smart doorbell can be intelligently adjusted in different scenes, ensuring that when the visitor position changes, the smart doorbell always has a more appropriate volume effect. This solution not only solves the shortcomings of infrared sensors in detecting visitor positions, but also solves the problem of unfixed visitor positions and poor voice call effects, and can also improve the service life of the smart doorbell audio system; at the same time, it is conducive to the development of smart doorbells in the direction of intelligence and humanization.

[0102] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the first embodiment can refer to the above introduction, and will not be repeated in the following. Figure 2 , after step S50, the smart doorbell control method also includes step S60.

[0103] Step S60: adjusting the sensitivity of the audio module according to the compensation result.

[0104] Specifically, since the sensitivity of the speaker and the microphone is mainly affected by the distance, during adjustment, the sensitivity of the speaker and the microphone can be adjusted accordingly according to the location of the visitor.

[0105] In addition, the adjustment values ​​of the microphone and the speaker may be consistent. This embodiment is mainly described by taking the speaker as an example.

[0106] As an implementation method, the current position of the visitor can be detected by an ultrasonic sensor, that is, the current distance between the visitor and the smart doorbell can be determined; the difference between the current position of the visitor and the initial distance is calculated to obtain the distance difference; the sound pressure level difference of the audio module is calculated based on the distance difference; the current volume of the smart doorbell is compensated based on the sound pressure level difference of the audio module, and finally, the sensitivity of the audio module is adjusted based on the compensation result.

[0107] Among them, for the specific implementation principle of compensating the current volume of the smart doorbell, please refer to the above embodiment and will not be repeated here.

[0108] The technical solution of this embodiment uses a built-in ultrasonic sensor to identify the location of visitors around the smart doorbell, and dynamically adjusts the volume of audio modules such as the doorbell speaker (horn) and microphone through volume compensation in combination with the distance between the visitor's location and the smart doorbell. Therefore, the volume of the speaker and microphone of the smart doorbell can be intelligently adjusted in different scenarios to ensure that when the visitor's location changes, the smart doorbell always has a relatively suitable volume effect. Furthermore, the user's location can be fed back to the MCU chip to adjust the amplification factor of the built-in power amplifier module, thereby intelligently adjusting the sensitivity of the speaker and microphone of the smart doorbell in different scenarios. This solution not only solves the shortcomings of infrared sensors in detecting visitor locations, but also solves the problem of unstable visitor locations and poor voice call effects, and can also improve the service life of the smart doorbell audio system; at the same time, it is conducive to the development of smart doorbells in the direction of intelligence and humanity.

[0109] Based on the first embodiment or the second embodiment of the present application, in the third embodiment of the present application, the same or similar contents as those of the first embodiment or the second embodiment can refer to the above introduction, and will not be repeated later. Figure 3, after step S50, the smart doorbell control method also includes step S70.

[0110] Step S70, detecting by the ultrasonic sensor whether the position of the target person changes;

[0111] If it is detected that the position of the target person has changed, return to step S30: perform a difference calculation based on the current position of the target person and the initial distance to obtain a distance difference, so as to determine again whether the current volume of the smart doorbell needs to be compensated according to the current position of the target person, and / or determine whether the sensitivity of the audio module needs to be adjusted.

[0112] As an implementation method, if it is detected that the position of the target person changes, the process returns to step S30 and subsequent steps.

[0113] The complete process of this embodiment can be referred to Figure 4 shown.

[0114] This embodiment adopts the above scheme, specifically by responding to the detection of the target person, determining the initial distance corresponding to the current volume of the audio module according to the current scene; detecting the current position of the target person by means of an ultrasonic sensor; performing a difference calculation between the current position of the target person and the initial distance to obtain a distance difference; calculating the sound pressure level difference of the audio module based on the distance difference; and compensating for the current volume of the smart doorbell based on the sound pressure level difference of the audio module. In addition, the ultrasonic sensor can also be used to detect whether the position of the target person has changed; if the position of the target person is detected to have changed, then it is determined again based on the current position of the target person whether the current volume of the smart doorbell needs to be compensated, and / or whether the sensitivity of the audio module needs to be adjusted. This solution uses a built-in ultrasonic sensor to identify the visitor position around the smart doorbell, and combines the distance between the visitor position and the smart doorbell to dynamically adjust the volume of the doorbell speaker (horn), microphone and other audio modules through volume compensation, so that the volume of the speaker and microphone of the smart doorbell can be intelligently adjusted in different scenarios to ensure that when the visitor position changes, the smart doorbell always has a relatively suitable volume effect, and the sensitivity can be further adjusted. This solution not only solves the shortcomings of infrared sensors in detecting visitor positions, but also solves the problem of unstable visitor positions and poor voice call effects, and can also improve the service life of the smart doorbell audio system; at the same time, it is conducive to the development of smart doorbells in the direction of intelligence and humanity.

[0139] One or more technical solutions proposed in this application have at least the following technical effects: by responding to the detection of the target person, determining the initial distance corresponding to the current volume of the audio module according to the current scene; detecting the current position of the target person by an ultrasonic sensor; performing difference calculation based on the current position of the target person and the initial distance to obtain the distance difference; calculating the sound pressure level difference of the audio module based on the distance difference; and compensating the current volume of the smart doorbell based on the sound pressure level difference of the audio module.
