Problems solved by technology

Elastic parts are often accompanied by rattling noises during the rebound process; touch buttons have strict environmental requirements and are not suitable for use in environments with high humidity. They often cannot be used when fingers are wet. When it is magnetically sensitive, it may cause the keys to fail

Embodiment 1

[0030] combine Figure 1-Figure 2 , the present invention proposes a water heater control device based on plane gesture recognition, including an input detection unit, a main control unit, a water heater control unit and a display unit;

[0031] The input detection unit is used to receive the reflected light of the infrared light supplement 2 on the object, capture the gesture image formed by the user in the operation area, and send the captured gesture image to the main control unit; the input detection The unit includes a camera sensor 1 with an optical filter and an infrared light supplement 2. The filter can only pass through the infrared light with the same wavelength as the infrared supplementary light device 2 . The operating area 3 of the water heater is projected on the wall plane by the operating area projection device 4, which uses a laser to project a visible static pattern, and the content of the pattern is determined by the pattern printed on the film installed ...

Embodiment 2

[0045] combine image 3 , using a single-finger click method to adjust the temperature of the water heater, using the OV7620 camera and 808nm narrow-band filter as the input detection unit, and the infrared supplementary light device emits an infrared line with a wavelength of 808nm to the outside; this platform uses ST's stm32f407 as the main The control unit chip; the water heater control unit adopts the method of relay plus resistance wire, and adds a pt100 thermocouple sensor to detect the water temperature; the display unit adopts the method of triode driving the digital tube to display the set temperature value and the actual temperature value.

[0046] 1. System hardware initialization:

[0047] The initialization process includes: initializing the ov7620 camera, configuring a PWM output to drive the 808nm infrared light supplement, initializing the GPIO used to control the relay, initializing the GPIO used to drive the digital tube, and initializing the modulus used to...

Abstract

The invention provides a water heater control device and method based on plane gesture recognition. The control device comprises an input detection unit, a main control unit, a water heater control unit and a display unit. Plane gesture control is used for a water heater, plane gesture control replaces the traditional scheme adopting pressure keys and touch keys, the space occupied by a control panel of the water heater can be saved, the user gestures are detected by a camera sensor, the visual angle is wider, the operable region is larger, no noise is generated, no mechanical wear is generated, control can be completed without hard pressing, the cost is low, mounting and maintaining are easy, the environment requirement is not strict, accurate recognition can also be achieved when the finger makes contact with water, the operation manner is novel and saves labor, and better user experience is provided.

Description

technical field [0001] The invention belongs to the technical field of water heaters, in particular to a water heater control device and control method based on plane gesture recognition. Background technique [0002] Existing water heaters usually use pressure buttons or touch buttons as control methods, and the pressure buttons need to occupy a certain amount of panel space, and as the functions of the water heater increase, the number of buttons also increases, which leads to excessive space occupied by the control panel. Big. The use of the pressure button requires a certain amount of pressure. And when the key rebounds, it will produce a certain amount of noise; when the water mist touches the key, the recognition accuracy will be greatly reduced. Especially in the case of wet fingers, the keys can hardly recognize the operation of the fingers. [0003] Pressure button: Pressing the finger causes the elastic component inside to deform elastically and connect the cont...
