[0036] At present, most of the existing wired controllers are controlled through physical button scanning and touch buttons. However, the physical button scanning control method is prone to wear and tear due to long-term use, and the touch buttons are prone to malfunction due to the user's wet or dirty fingers. A small number of them use image recognition through cameras to achieve contactless control, but image recognition often needs to be turned on for a long time and requires real-time calculation and analysis of image data, which causes the wired controller controlled by image recognition to have a certain control delay and high energy consumption.

[0037] Based on this, an embodiment of the present invention provides a wire controller based on gesture recognition control. The wire controller comprises an MCU controller, a gesture recognition sensor, and an LCD display driver. The MCU controller and the gesture recognition sensor are circuit-connected, and the MCU controller and the LCD display driver are circuit-connected. The gesture recognition sensor has a wake-up function. The gesture recognition sensor is configured to enter a sleep state when no gesture is recognized for a long period of time or to enter a wake-up state when a hand is sensed within a recognizable area. The gesture recognition sensor is further configured to recognize gestures within the recognizable area using infrared thermal imaging and to send gesture commands generated based on the recognized gestures to the MCU controller. The MCU controller is configured to receive the gesture commands and, based on the gesture commands, send corresponding application commands to an external appliance. The MCU controller is further configured to receive feedback from the external appliance and send the feedback to the LCD display driver. The LCD display driver is configured to receive and display the feedback. Thus, gestures can be recognized through infrared thermal imaging and the LCD display driver can display the feedback in real time. Complex image data processing is not required to achieve real-time control and feedback of gesture recognition, thereby improving the real-time performance of the wire controller in contactless control. Furthermore, the wake-up function in the gesture recognition sensor further reduces the overall energy consumption of the wire controller.

[0038] Therefore, the embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0039] Reference Figures 1 to 4 As shown, Figure 1 This is an overall structural diagram of a wire controller based on gesture recognition control provided by an embodiment of the present invention. Figure 2 This is a circuit diagram of an MCU controller provided by an embodiment of the present invention. Figure 3 This is a circuit diagram of a gesture recognition sensor provided by an embodiment of the present invention. Figure 4 This is a circuit structure diagram of an LCD display driver provided by an embodiment of the present invention. The wire controller based on gesture recognition control includes an MCU controller 101, a gesture recognition sensor 102 and an LCD display driver 103. The MCU controller 101 is circuit-connected to the gesture recognition sensor 102, and the MCU controller 101 is circuit-connected to the LCD display driver 103.

[0040] Among them, the gesture recognition sensor 102 is provided with a wake-up sleep function. The gesture recognition sensor 102 is used to enter a sleep state when no gesture action is recognized for a long time or to enter a wake-up state when a hand is sensed in the recognizable area. The wake-up sleep function in the gesture recognition sensor 102 can reduce the overall energy consumption of the wire controller.

[0041] In an optional embodiment, when the user waves his hand within the recognizable area of ​​the gesture recognition sensor 102 , the gesture recognition sensor 102 is immediately awakened, and begins to recognize gestures the next time the user waves his hand.

[0042] At the same time, the gesture recognition sensor 102 is also used to identify gesture actions within the recognizable area in the form of infrared thermal imaging and to send gesture instructions generated based on the recognized gesture actions to the MCU controller 101, thereby being able to identify gesture actions through infrared thermal imaging, without the need for complex image data processing to achieve real-time control of gesture recognition, thereby improving the real-time performance of the wire controller in contactless control.

[0043] Among them, the MCU controller 101 is used to receive gesture instructions and send corresponding application instructions to external electrical appliances according to the gesture instructions. The MCU controller 101 is also used to receive feedback information from external electrical appliances and send feedback information to the LCD display driver 103. The LCD display driver 103 is used to receive and display feedback information, and then the feedback can be displayed in real time through the LCD display driver 103, thereby improving the real-time controllability of the contactless wire controller.

[0044] In an optional embodiment, when the MCU controller 101 receives a gesture command, it generates a corresponding application instruction based on the gesture instruction and sends the application instruction to the external appliance. When the external appliance successfully executes the application instruction, it sends feedback information to the MCU controller 101. Upon receiving the feedback information, the MCU controller 101 sends the feedback information to the LCD display driver 103. Upon receiving the feedback information, the LCD display driver 103 displays a message "Gesture execution successful" on the corresponding UI interface. Simultaneously, the MCU controller 101 sends the feedback information to the gesture recognition sensor 102 via the serial port Tx. If the gesture recognition sensor 102 times out and fails to receive the gesture instruction, it resends the gesture instruction to the MCU controller 101. If the gesture recognition sensor 102 fails to resend the gesture instruction more than three times, the LCD display driver 103 displays a message "Gesture execution failed, please try again" on the corresponding UI interface.

[0045] It should be noted that the gesture recognition sensor 102 can recognize the user's waving motions to the left, right, up, down, forward, and backward, and can also recognize the hovering short press and hovering long press gestures.

[0046] In an optional embodiment, the external appliance is an air conditioner, and the MCU controller 101 can convert the "wave upward" gesture instruction sent by the gesture recognition sensor 102 into an application instruction of "setting the air conditioner temperature to increase"; convert the "wave downward" gesture instruction sent by the gesture recognition sensor 102 into an application instruction of "setting the air conditioner temperature to decrease"; convert the "wave right" gesture instruction sent by the gesture recognition sensor 102 into an application instruction of "setting the wind speed to increase"; convert the "wave left" gesture instruction sent by the gesture recognition sensor 102 into an application instruction of "setting the wind speed to turn down"; and convert the "wave right" gesture instruction sent by the gesture recognition sensor 102 into an application instruction of "setting the wind speed to turn down". The gesture command of “waving forward” sent by the gesture recognition sensor 102 is converted into an application command of “setting brightness up”; the gesture command of “waving backward” sent by the gesture recognition sensor 102 is converted into an application command of “setting brightness down”; the gesture command of “hovering, short pressing and waving in a specified direction” sent by the gesture recognition sensor 102 is converted into an application command of “switching the UI page in the wire controller in a specified direction”; the gesture command of “hovering, long pressing” sent by the gesture recognition sensor 102 is converted into an application command of “clicking on this function”.
