FIG. 6 is a flowchart of a control method of a steam oven identification and safety system according to an embodiment of the present invention. As shown in FIG. 6 , the application process of the system control method provided by the embodiment of the present invention includes the following processes:

(1) Turn on the device, start the camera, and adjust the camera angle. Specifically, the default angle of the vertical direction of the camera can be set at the display operation panel, and the main control board controls the rotation of the vertical rotation motor according to the relevant parameter settings, so that the camera can be rotated to an appropriate angle to ensure that the visual range of the camera is large enough. , can perform food identification and security scanning.

(2) The box door is opened, the camera is rotated horizontally to the position inside the box, the food is put in, and the box door is closed. Specifically, the main control board sends control instructions to control the horizontal rotation motor to rotate the camera to a position facing the inside of the box.

(3) The camera scans the food to be steamed and roasted in the box, and transmits the collected image signal to the main control board. The main control board judges whether the relevant ingredients are scanned through the internal algorithm. If the relevant ingredients are scanned, the main control board judges whether There is a menu corresponding to the ingredients. If there is a corresponding menu, the steaming operation of the corresponding menu will be performed according to the menu, and a control signal will be sent to the display operation panel to display the corresponding interface; if the relevant ingredients are not scanned or the corresponding menu does not exist, a prompt will be displayed. "Scanning error, please put the ingredients back into the box for scanning." At this time, you need to reopen the box door and put in the correct ingredients or adjust the position of the ingredients so that they can be scanned by the camera. You can also manually set the parameters; if scanning If the obtained menu is not the desired menu or the menu is incorrect, it needs to be terminated manually, and scan again or directly set the parameters manually.

(4) When the equipment starts to run the normal steaming operation, the main controller sends a command to control the horizontal rotation motor to rotate the camera about 180°, so that the camera rotates to the position outside the box, and scans whether anyone is approaching.

(5) When the camera scans that someone is approaching, the main control board determines whether it is a child, and sends a control signal to adjust the camera angle. Specifically, the camera transmits the recognized parameters such as body height, body characteristics, and proximity distance to the main control board, and the main control board sends control signals to the vertical rotation motor through the internal algorithm to adjust the camera angle to improve the sampling information, and then judges. Are children and within a dangerous distance. If it is judged that it is a child, it will send a control signal to the display operation panel to lock the button and forcibly lock the door lock; if it is judged that it is not a child, it will restore the camera to the default angle and continue scanning.

(6) When the steaming operation is finished or manually terminated, the camera rotates into the box in the horizontal direction, and rotates to the default angle in the vertical direction, the device is turned off, and the camera is turned off. At this time, the door of the box can be opened normally to take out the food.

The cooking appliance identification and safety system, control method and cooking appliance provided by the embodiments of the present invention can identify whether there is a child approaching the cooking appliance through a camera, transmit the information to the main control panel in the background, and start the operation when it is judged that it is a child Safety measures; at the same time, the camera can identify the ingredients to be cooked, and after the information is transmitted to the main control panel in the background, the corresponding cooking plan can be started; further, the rotation of the camera can be controlled by the rotating bracket, so as to achieve the above two modes. Free switching That is, when the horizontally rotating motor controls the camera to face the inside of the box, it can identify the cooking food, and when it faces outside the box, it can judge whether the child is approaching, which alleviates the technical problem in the prior art that both human body recognition and to-be-cooked ingredients can not be recognized.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, but not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: The technical solutions described in the foregoing embodiments can still be modified, or some or all of the technical features thereof can be equivalently replaced; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the technical solutions of the embodiments of the present invention. scope.
