Detailed Description
The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.
The recognition of the range hood on the size of the oil smoke is mainly realized by an image recognition module, the image recognition module can comprise an image processing main controller and a visual camera, the visual camera can collect oil smoke images, then the image processing main controller processes the images into corresponding oil smoke data to output, and the rotating speed of a fan of the range hood can be controlled according to the output oil smoke data. The rotating speed of the fan is directly determined by the oil smoke data, and the wind following smoke function that the rotating speed of the fan is high when the oil smoke is large and the rotating speed of the fan is low when the oil smoke is small is realized.
Currently, a single image recognition module has the following problems: one is gesture false recognition. For example, when the temperature in the pan does not reach the condition of generating oil smoke during uncooked or cooking, and when the gesture action of quickly waving the arm exists in the range of the visual camera, the image recognition module can misrecognize the gesture action as oil smoke generation, so that oil smoke data is output, and the situation of misstarting a fan occurs. The other is that the shadow interferes with the misrecognition, for example, under the condition that the temperature in the pot does not reach and produces the oil smoke when not cooking or cooking, when there is the shadow to rock in the vision camera scope, image recognition module can sometimes shake the shadow misrecognition and take place for the oil smoke, leads to there is oil smoke numerical value output, appears the condition that the fan was started by mistake to lead to user experience poor.
Fig. 1 is a flowchart of a control method of a range hood, where the method may be performed by a range hood control device, the device may be implemented by software and/or hardware, the device may be configured in a range hood, and the method may be applied to a situation that a shadow or motion interference image recognition module recognizes a range hood.
As shown in fig. 1, the technical solution provided by the embodiment of the present invention includes:
s110: and acquiring an oil smoke image in the cooking process through an image identification module, and monitoring the temperature in the pot through an infrared temperature sensor.

S120: and when the temperature in the pot is smaller than the fuming temperature, prohibiting the determination of the oil smoke data based on the oil smoke image by the image recognition module.
In embodiments of the invention, the fuming temperature may be 170 ℃. When the temperature in the cooker is less than the smoke generating temperature, the cooker basically does not generate oil smoke, so that the image recognition function of the image recognition module is closed, oil smoke data is not output, namely the image recognition module is prohibited from determining the oil smoke data based on the oil smoke image, and a fan of the range hood is not started at the moment. When gesture actions or human shadows with extremely high similarity to the oil smoke appear in the oil smoke image and shake, the gesture or human shadows interfere with the oil smoke image so that the oil smoke is in a closed state, and the false start of the oil smoke is not caused.
S130: when the temperature in the cooker is higher than the smoke generation temperature, determining oil smoke data based on the oil smoke image through the image recognition module, and controlling the rotating speed of a fan of the range hood based on the oil smoke data.
In the embodiment of the invention, the image processing main controller in the image recognition module can be based on oil smoke image oil smoke data, wherein the oil smoke data can comprise oil smoke concentration and oil smoke area or can also comprise other data representing the oil smoke.
In the embodiment of the invention, when the temperature in the cooker is higher than the smoke generating temperature, the cooker generates oil smoke, so oil smoke data is determined based on the oil smoke image through the image recognition module, the rotating speed of the fan of the range hood is controlled based on the oil smoke data, and the oil smoke is discharged out of the chamber. Under the condition, when the oil smoke image is subjected to gesture motion or figure shaking with extremely high oil smoke similarity, the oil smoke extractor needs to be started because the oil smoke image is in an oil smoke state at the moment, and therefore the gesture or figure interference cannot influence the starting of the oil smoke extractor. In one example embodiment, controlling the rotational speed of the range hood fan based on the range hood data may include; when the oil smoke concentration is larger and the oil smoke area is larger, controlling the rotating speed of a fan of the range hood to be larger; when the oil smoke concentration is smaller and the oil smoke area is smaller, the rotating speed of the fan of the range hood is controlled to be smaller. Or may include: when the oil smoke concentration is larger than the set concentration, the rotating speed of the fan of the range hood is adjusted to correspond to the first oil smoke area, or when the oil smoke concentration is smaller than the set concentration, the rotating speed of the fan of the range hood is adjusted to correspond to the oil smoke area. Or can comprise adjusting the rotational speed of the range hood to correspond to the concentration of the oil smoke when the oil smoke area is greater than the set area, or adjusting the rotational speed of the range hood to correspond to the concentration of the oil smoke when the oil smoke area is less than the set area.
According to the technical scheme provided by the embodiment of the invention, the image recognition module is used for collecting the oil smoke image in the cooking process, and the infrared temperature sensor is used for monitoring the temperature in the pot; when the temperature in the cooker is lower than the smoke temperature, the image recognition module is prohibited from determining the oil smoke data based on the oil smoke image, so that the starting of the range hood can be prohibited, and the situation of false starting of the range hood caused by gesture actions or human shadow interference is avoided; when the temperature in the cooker is higher than the smoke generation temperature, the image recognition module is used for determining the oil smoke data based on the oil smoke image, and the rotating speed of the fan of the range hood is controlled based on the oil smoke data, so that gesture actions or artifacts cannot influence the starting of the range hood, and the false starting of the range hood is avoided.

S240: when the temperature in the pot is greater than the preset temperature, determining oil smoke data based on the oil smoke image through the image recognition module; wherein the preset temperature is greater than the fuming temperature.
In the embodiment of the invention, the preset temperature can be set according to the requirement and is higher than the fuming temperature. For example, the preset temperature may be 250 ℃ and the fuming temperature may be 170 ℃.
S250: when the value of the oil smoke data is smaller than a preset value, compensating the value of the oil smoke data, and controlling the rotating speed of the fan of the range hood based on the compensated value.
In the embodiment of the invention, the preset value is the value of the oil smoke data corresponding to the preset temperature. When the temperature in the cooker is higher than the preset temperature and the value of the oil smoke data determined based on the oil smoke image through the image recognition module is lower than the preset value, the value of the oil smoke data is compensated, and the rotating speed of the fan of the range hood is controlled based on the compensated value. The numerical value of the compensation oil smoke data can be specifically: and compensating the numerical value of the oil smoke data to be the same as the numerical value of the oil smoke data corresponding to the temperature in the pot, and controlling the rotating speed of the fan of the range hood based on the compensated numerical value.
