Referring to fig. 1, a block diagram of an intelligent appliance according to an exemplary embodiment of the present application is shown. The intelligent household appliance shown in fig. 1 can be an intelligent household appliance in a kitchen such as an intelligent integrated stove and an intelligent range hood. This intelligent household electrical appliance can include: master controller and camera. In an optional embodiment, the smart appliance may further include: an infrared distance sensor. The main controller can control the camera and the infrared distance sensor, and can also acquire images shot by the camera and output results of the infrared distance sensor.
Referring to fig. 2, a flowchart of an overflow detection method according to an exemplary embodiment of the present application is shown. The method can be applied to the master controller included in the intelligent household appliance shown in fig. 1, and certainly, the intelligent household appliance can also include a camera. The method may comprise the steps of:
step 201: the method comprises the steps of obtaining a first image of a preset area of a kitchen, wherein the preset area of the kitchen comprises target household appliances in an overflowing state, and the first image is an image of the target household appliances in a non-overflowing state.
Step 202: and after an overflow detection instruction is detected, acquiring a current image of the preset kitchen area as a second image at preset detection time intervals.
In this embodiment, the kitchen predetermined area may be an area including a target appliance having an overflow state, for example: because the pan (namely the target household appliance) used may overflow when cooking porridge, soup and the like on the cooking bench, namely has an overflow state, the cooking bench area can be used as a kitchen preset area, so that the installation position and direction of the camera in the intelligent household appliance can be adjusted, and the camera can shoot images of the kitchen preset area.
A main controller in the intelligent household appliance can acquire a first image of a preset area of a kitchen through a camera in the intelligent household appliance. Wherein the first image may be an image of a target appliance in a predetermined area of the kitchen in an unswollen state, such as: when the preset kitchen area is a cooking bench area and the target household appliance is a pot, the first image is an image of the cooking bench area shot by the camera when the pot is in a non-overflowing state.
In an alternative embodiment, when the target household appliance in the predetermined area of the kitchen does not start to work, the user can call the camera through the master controller, and the camera shoots the predetermined area of the kitchen to obtain an image of the predetermined area of the kitchen when the target household appliance is in a non-overflow state. Specifically, the master controller may provide a user interface for a user, and the user may initiate a shooting operation when a target appliance in a predetermined area of the kitchen has not started to work through the user interface, and the master controller may invoke the camera to shoot the predetermined area of the kitchen after detecting the shooting operation. After the main controller acquires the image of the kitchen preset area when the target household appliance is in the non-overflow state, which is shot by the camera, the main controller can save the image as a first image of the kitchen preset area locally, namely, the main controller can directly acquire the first image of the kitchen preset area which is prestored locally subsequently.
Or the main controller can call the camera to acquire a first image of a preset area of the kitchen when the overflow detection instruction is detected. Specifically, the master controller may provide a user interface for a user, the user may initiate an overflow detection operation through the user interface, and the master controller may regard that an overflow detection instruction is detected after the overflow detection operation is detected, so that the camera may be called to shoot the predetermined kitchen area, so as to obtain an image of the predetermined kitchen area when the target household appliance is in a non-overflow state, and determine the image as a first image of the predetermined kitchen area.
In another embodiment, the intelligent appliance shown in fig. 1 may further include an infrared distance sensor. The main controller can detect whether users are near the preset area of the kitchen or not through the output result of the infrared distance sensor. If a user is near the predetermined area of the kitchen, the user can judge whether the overflow condition exists without starting the overflow detection function. However, if the main controller detects that there is no user near the predetermined area of the kitchen based on the output result of the infrared distance sensor, a timer may be started to count the duration of time during which no user is detected; after the duration that the user is not detected is determined to reach the preset overflow detection time, the user can be considered to leave the preset kitchen area, and whether the overflow condition exists can not be judged by himself, so that the main controller can be considered to detect the overflow detection instruction at the moment, and the first image of the preset kitchen area can be acquired through the camera. It should be noted that the overflow detection time may be set by the user through a user interface provided by the main controller, or may be a default value, which is not limited in this application.
Subsequently, after the main controller in the intelligent household appliance detects the overflow detection instruction, the current image of the preset area of the kitchen can be acquired as the second image through the camera in the intelligent household appliance at a preset detection time interval. The detection time interval may be set by the user through a user interface provided by the master controller, or may be a default value, which is not limited in this application. In this way, the master controller can compare the first image and the second image of the predetermined area of the kitchen to determine whether the target household appliance in the predetermined area of the kitchen overflows.
Step 203: and judging whether the second image is matched with the first image.
Step 204: and if the second image does not match the first image, executing overflow alarm operation.
In this embodiment, after the master in the smart home appliance acquires the first image and the second image of the predetermined area in the kitchen in the foregoing steps 201 and 202, the master may compare the first image and the second image to determine whether the first image and the second image are matched. Since the first image is an image of a target household appliance in the predetermined area of the kitchen when the target household appliance is in a non-overflow state, if the first image and the second image are matched, it can be determined that the target household appliance is still in the non-overflow state at this time, and it can be considered that the target household appliance has not been overflowed yet; if the first image and the second image are not matched, the target household appliance can be determined to be no longer in a non-overflow state at the moment, namely the target household appliance can be considered to be overflowed, and in this case, the master controller can execute an overflow alarm operation.
It can be seen from the above embodiments that, a master controller in an intelligent household appliance in a kitchen, such as an intelligent integrated cooker, an intelligent range hood, or the like, may determine, for a predetermined area of the kitchen including a target household appliance having an overflow state, whether a second image of the predetermined area of the kitchen, which is currently acquired, matches a first image of the predetermined area of the kitchen, which is acquired before, and may perform an overflow alarm operation when the second image is not matched with the first image, so as to remind a user that the target household appliance has an overflow because the first image is an image when the target household appliance in the predetermined area of the kitchen is in a non-overflow state. By adopting the mode, when no person is in a kitchen, the master controller in the intelligent household appliance can automatically judge whether the overflow condition occurs, so that the user can be timely reminded when the overflow condition occurs, and the potential safety hazard is avoided.
Specifically, referring to fig. 3, the following steps may be adopted to determine whether the second image matches the first image, and when the second image does not match the first image, perform an overflow alarm operation:
step 2031: and acquiring first state information of the target household appliance in the first image, and acquiring second state information of the target household appliance in the second image.
Step 2032: and judging whether the first state information is the same as the second state information.
Step 2033: and if the first state information is different from the second state information, executing overflow alarm operation.
In this embodiment, after acquiring the first image and the second image of the predetermined area of the kitchen in the foregoing steps 201 and 202, the master in the smart home appliance may acquire first state information of the target home appliance in the first image (i.e., the target home appliance having an overflow state in the predetermined area of the kitchen), and acquire second state information of the target home appliance in the second image.
Subsequently, the master may determine whether the first state information and the second state information are the same. If the first image and the second image are the same, the first image and the second image can be considered to be matched, so that the target household appliance can be considered not to overflow; if the two are different, the first image and the second image can be regarded as not matching, so that the target household appliance can be regarded as overflowing, and in this case, the master controller can execute an overflowing alarming operation.
In an alternative embodiment, the status information may be location, shape, size, color, etc.
For example, assume that the predetermined area of the kitchen is a cooktop area, the target appliance is a pot, and the status information is a color. Because white bubbles appear at the edge of the pot cover when the pot overflows, the color of the pot in the first image and the color of the pot in the second image are different, namely the first state information is different from the second state information. In this case, the master controller may determine that the pan (i.e., the target appliance) has overflowed, and perform an overflow alarm operation.
In another example, it is assumed that the predetermined area of the kitchen is a cooktop area, the target appliance is a pot, and the status information is a size. Due to the coverage of the white bubbles at the edge of the pot cover during the overflow, the size of the pot in the first image may be different from the size of the pot in the second image, that is, the first state information is different from the second state information. In this case, the master controller may also determine that the pan (i.e., the target appliance) has overflowed, and perform an overflow alarm operation.
In order to improve efficiency of acquiring the state information of the target appliance in the image, in an alternative embodiment, an initial image of a predetermined area of the kitchen excluding the target appliance may be further preset. Specifically, when the target household appliance is not yet installed in the predetermined area of the kitchen, the user can call the camera in the intelligent household appliance through the main controller in the intelligent household appliance, and the predetermined area of the kitchen is shot by the camera to obtain an initial image of the predetermined area of the kitchen, which does not include the target household appliance. For example, the master controller may provide a user interface through which the user may initiate a photographing operation when the target appliance has not been placed in a predetermined area of the kitchen, and the master controller may invoke the camera to photograph the predetermined area of the kitchen after detecting the photographing operation. After the main controller acquires the initial image of the preset area of the kitchen, which is shot by the camera and does not comprise the target household appliance, the initial image can be stored locally, namely the initial image can be directly acquired subsequently.
In this way, after the first image of the kitchen area including the target household appliance is acquired, the first image can be compared with the initial image, so that the first state information of the target household appliance in the first image is directly acquired; similarly, after the second image of the kitchen area including the target household appliance is acquired, the second image may be compared with the initial image, so as to directly acquire the second state information of the target household appliance in the second image. After the first state information and the second state information of the target household appliance are obtained, whether the target household appliance overflows or not can be determined by judging whether the first state information is the same as the second state information or not, namely when the first state information is different from the second state information, the main controller can determine that the target household appliance overflows, and therefore overflow alarm operation can be executed.
In another alternative embodiment, the master in the intelligent appliance may perform the overflow alarm operation in the following manner, including: control reduces or turns off the fire, for example: sending a control message to the cooktop, thereby causing the cooktop to reduce or turn off the fire; and/or outputting overflow alarm information locally in a voice or text mode, such as: reminding a user of overflow by voice, sending an alarm to remind the user, popping up a window displaying overflow warning characters in a user interface, and the like; and/or sending overflow alarm information to a user terminal connected with the intelligent household appliance. Therefore, the user can be reminded of overflowing, so that the user can check and solve the overflowing problem in time.
