detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

The control method provided by the embodiment of the present invention will be described in detail below.

Embodiment one:

This embodiment provides a control method for a range hood, as shown in FIG. 1 , the above control method includes:

S201: Detect whether there is a target object in the preset recognition area of the range hood;

Here, it can be understood that in this embodiment, a human body proximity sensor, such as a pyroelectric human body infrared sensor, an infrared reflective sensor or a Doppler sensor, can be used to detect whether there is a target object in the preset recognition area of the range hood, It is also possible to detect whether there is a target object in the preset recognition area of the range hood through an image acquisition sensor, such as a camera, a face recognition device or an action recognition device. For the convenience of description, in this embodiment, the pyroelectric human body infrared sensor is taken as an example to further explain whether there is a target object in the preset recognition area of the range hood. The temperature difference of the background environment is used to detect whether there is a target object in the preset recognition area. The working principle is to use the pyroelectric effect. When someone passes by, the heat received by the two pyroelectric elements is different, and the pyroelectric energy is different. After being processed by the signal processing circuit and the signal amplification circuit, the microprocessor can perceive the distance between the human body and the range hood by judging the width of the output pulse of the pyroelectric human body infrared sensor, and then judge whether there is a target object in the preset recognition area. The discharge human body infrared sensor has the advantages of fast response speed, strong sensitivity and high accuracy in the process of detecting whether there is a target object in the preset recognition area of the range hood.

S202: If the existence of the target object is detected, collect the sound signal of the environment where the range hood is located;

Here, it can be understood that the above-mentioned sound signal can be the sound signal collected by the cooking sound recognition sensor. It should be noted that the cooking sound recognition sensor can be placed on the range hood, or on the cooker, or placed in other places , subject to realizing the collection of sound signals in the space where the range hood is located, which is not specifically limited in this embodiment of the present invention.

S203: comparing the sound signal with a preset cooking sound signal;

Specifically, the sound signal includes various sound signals of the environment where the range hood is located. The purpose of comparing the sound signal with the preset cooking sound signal is not only to determine whether the sound in the sound signal is cooking sound, but also to It is judged what kind of cooking sound signal the sound signal is.

It should be noted that the aforementioned preset cooking sound signals may include several characteristic sound signals when cooking food. Of course, those skilled in the art may also set the preset cooking sound signal according to actual cooking characteristics, which is not specifically limited in the embodiment of the present invention.

S204: If the sound signal belongs to the preset cooking sound signal, start the range hood.

Here, it can be understood that if the above-mentioned sound signal belongs to the preset cooking sound signal, it is judged that the sound signal of the environment where the range hood is collected by the cooking sound recognition sensor belongs to the preset cooking sound signal, and at this time, start the range hood , Quickly suck away the oily fumes generated during cooking.

It can be seen from this that in this embodiment, firstly, it is detected whether there is a target object in the preset recognition area of the range hood; secondly, if the presence of the target object is detected, the sound signal of the environment where the range hood is located is collected; and then , compare the sound signal with the preset cooking sound signal; finally, if the sound signal belongs to the preset cooking sound signal, start the range hood, so that the range hood can be automatically turned on and off without manual control by the user, and further Specifically, this embodiment combines the detection of the target object and the collection of the cooking sound signal, avoiding the problem that the single detection of the target object or the collection of the cooking sound signal may cause the range hood to start up by mistake, and improves the reliability of the intelligent control of the range hood.

Further, referring to FIG. 2 , when it is determined in step S204 that the above-mentioned sound signal belongs to the preset cooking sound signal, and after starting the range hood, the control method further includes:

S205: Obtain characteristic parameters of the sound signal;

Here, it can be understood that the above characteristic parameters may include volume parameters of the acquired sound signal.

S206: Query the mapping relationship between the preset sound signal characteristic parameters and the control instructions according to the characteristic parameters, and obtain the control instructions corresponding to the characteristic parameters;

Here, it can be understood that the above-mentioned preset sound signal characteristic parameter may be a sound volume parameter range, and there is a mapping relationship between different sound volume parameter ranges and different control instructions. After the sound volume parameter of the sound signal is obtained, query the preset sound volume parameter range corresponding to the sound volume parameter of the above sound signal, and after determining the preset sound volume parameter range to which the sound volume parameter belongs, according to the preset sound volume parameter range and control The mapping relationship between the instructions obtains the corresponding control instruction, and the control instruction can be used to control the fan speed of the range hood.

Here, only the volume parameter of the sound signal obtained when the characteristic parameter is cooking is used as an example for illustration, and the implementation of the control method in this embodiment shall prevail, and no specific limitation is made. For example, in the process of cooking, the characteristic parameters of the sound signal obtained in sequence include the first characteristic parameter, the second characteristic parameter and the third characteristic parameter, wherein the first characteristic parameter is the sound volume parameter when the dish is just out of the pot (here The sound volume parameter obtained at this time is A), the second characteristic parameter is the sound volume parameter when stir-frying (the sound volume parameter obtained at this time is B), and the third characteristic parameter is the sound volume parameter before the pot (obtained at this time The sound volume parameter is C), wherein A is greater than B, and B is greater than C. That is to say, the sound volume parameter of the sound signal obtained when the dish is just out of the pot is the largest, and the sound volume parameter of the sound signal obtained when the dish is about to come out of the pot is the smallest.

Further, query the preset sound volume parameter ranges corresponding to the above-mentioned first characteristic parameter, second characteristic parameter and third characteristic parameter, and obtain the above-mentioned first The first control instruction corresponding to the characteristic parameter (the first control instruction is used to control the fan speed of the range hood to the maximum), the second control instruction corresponding to the second characteristic parameter (the second control instruction is used to control the fan speed of the range hood Medium), the third control instruction corresponding to the third characteristic parameter (the third control instruction is used to control the minimum fan speed of the range hood).

S207: Control the fan speed of the range hood according to the control instruction;

Here, it can be understood that, according to the first control instruction, the fan speed of the range hood is controlled to be the maximum, so as to achieve the purpose of quickly discharging oil fume; according to the second control instruction, the fan speed of the range hood is controlled to be medium; The minimum speed is used to save energy.

Of course, those skilled in the art can also set the mapping relationship between the preset sound signal characteristic parameters and the control instructions according to actual needs, which is not specifically limited in the embodiment of the present invention.

It can be seen from this that in this embodiment, the mapping relationship between the preset sound signal characteristic parameters and control instructions can be queried according to the acquired characteristic parameters of the sound signal, and the control instruction corresponding to the characteristic parameters can be obtained for real-time adjustment. The fan speed of the range hood.

S208: Receive a shutdown signal of the cooker, and send a shutdown instruction to the range hood according to the shutdown signal.

Here, as described in conjunction with FIG. 3 , the cooking range 10 and the range hood 20 are connected wirelessly. The shutdown signal of the above-mentioned cooker can be obtained through detection by a switch detection device arranged on the cooker. The cooker in this embodiment is also provided with a wireless transmitting device, which is used to send a shutdown command to the range hood according to the shutdown signal of the cooker, and the range hood in this embodiment is provided with a wireless receiving device, which is used to receive the transmission signal of the wireless transmitting device . The above-mentioned wireless transmitting device and wireless receiving device transmit signals through wireless communication technology, wherein the above-mentioned wireless communication technology can be any of the following: Bluetooth communication technology, Wi-Fi (Wireless-Fidelity) wireless fidelity communication technology, ZigBee Zigbee Communication technology, nRF communication technology. Here, when the switch detection device of the cooker detects a shutdown signal of the cooker, the cooker sends a shutdown command to the range hood by wireless communication according to the shutdown signal, and controls the range hood to be turned off.

What needs to be explained here is that in the prior art, after the range hood is turned on, the fan speed of the range hood is not automatically adjusted according to the change of the cooking state, but the fan speed of the range hood is manually adjusted by manual control, or the fan speed of the range hood is manually adjusted during the whole cooking process. The range hood always runs at a fixed wind speed. For example, when the thermocouple detection module is used to control the fan speed of the range hood, when the thermocouple flame detection module detects that the flame is burning, the range hood controller controls the fan module to start working, and the fan starts at Fixed wind speed operation, when the thermocouple flame detection module detects that there is no flame burning on the cooker, the range hood controller controls the fan module to stop working, this solution cannot automatically adjust the range hood fan speed, so that the user needs to manually control while cooking The fan speed of the range hood affects the cooking effect and the user experience is poor. In the technical solution of this embodiment, by obtaining the control parameters corresponding to the preset cooking sound signals from the preset cooking database, and controlling the fan speed of the range hood according to the control parameters, the fan speed of the range hood is automatically adjustable. functions, energy saving and environmental protection, and has a high degree of user experience.

Further, referring to FIG. 4, comparing the sound signal with the preset cooking sound signal described in step S203 may include:

S2031: Comparing the sound signal with the preset cooking sound signal to obtain the similarity between the sound in the sound signal and the sound in the preset cooking sound signal;

S2032: Determine whether the similarity exceeds a preset threshold;

S2033: If the similarity exceeds the preset threshold, determine that the sound signal belongs to a preset cooking sound signal.

It should be noted here that the above-mentioned sound signal is the sound signal of the space where the range hood is located, and the sound signal collected by the cooking sound recognition sensor is still used as an example for illustration. For example, when the cooking sound recognition sensor collects the first sound signal (this When the sound in the first sound signal is the sound of the user washing dishes in the kitchen where the range hood is located), the first sound signal is compared with the preset cooking sound signal to obtain the sound in the first sound signal and the preset cooking sound signal. The first similarity S1 of the sound in the cooking sound signal; the above-mentioned preset threshold is S, and the above-mentioned first similarity S1 is less than the above-mentioned preset threshold S through comparison, that is to say, the current sound collected by the cooking sound recognition sensor The signal does not belong to the preset cooking sound signal, and the cooking sound recognition sensor continues to collect the sound signal of the space where the range hood is located. For another example, when the cooking sound recognition sensor collects the second sound signal (the sound in the second sound signal at this time is the corresponding "stinging" sound when the vegetables have just been cooked), the second sound signal The sound is compared with the sound in the preset cooking sound signal to obtain the second similarity S2 between the sound in the second sound signal and the sound in the preset cooking sound signal; the above-mentioned preset threshold is S, and the comparison is obtained If the second similarity S2 exceeds the preset threshold S, it is determined that the sound signal belongs to the preset cooking sound signal.

It can be seen that, in this embodiment, the sound in the collected sound signal is compared with the sound in the preset cooking sound signal to obtain the sound in the sound signal and the sound in the preset cooking sound signal. The similarity of the sound is used to judge whether the similarity exceeds the preset threshold. When the similarity exceeds the preset threshold, it is determined that the sound signal belongs to the preset cooking sound signal, and then the range hood is started to realize the intelligent control of the range hood. As a result, the accuracy of range hood control is improved.

Further, when it is determined in step S204 that the above-mentioned sound signal belongs to the preset cooking sound signal, and the range hood is started, the control method further includes: controlling the lighting device to be turned on, and controlling the speed of the fan of the range hood to be a peak speed.

Here, understandably, in order to facilitate the user to view the cooking process, when the range hood is started, the lighting equipment is controlled to be turned on, and the fan speed of the range hood is controlled to be at a peak speed, so as to discharge cooking fumes as soon as possible. In addition, when the range hood is started, the panel display interface of the range hood can also be controlled to light up, the indicator light to be turned on, etc., so as to facilitate the user to perform cooking-related operations. In this embodiment, in order to meet the brightness requirements in various kitchen environments, the range hood can also be provided with an illuminance sensor connected to the lighting equipment and a control unit connected to the illuminance sensor. The light intensity signal and transmit the signal to the control unit, the control unit controls the lighting equipment to adjust the brightness, adjust the brightness of the lighting equipment in real time, and then meet the light perception requirements of the human eye, and realize the effect of intelligent lighting brightness adjustment.
