Kitchen ventilator control system based on gesture recognition

Abstract

The invention relates to a kitchen ventilator control system based on gesture recognition, and the system comprises a central control system, a gesture collection and recognition system, a control result indication module, and a motor drive module. The system is characterized in that the gesture collection and recognition system consists of a microprocessor, a gesture sensor based on the technology of computer vision, and a wireless signal transmitting module; the gesture sensor enables a gesture signal to be transmitted to the microprocessor; the microprocessor converts a recognized gesture signal into a corresponding control instruction; the wireless signal transmitting module enables the control instruction transmitted by the microprocessor to be transmitted to the central control system in a wireless manner; the central control system consists of a microcontroller and a wireless signal receiving module; the wireless signal receiving module receives the control instruction transmitted by the gesture collection and recognition system; the microcontroller enables the control instruction to be converted into a control signal, and transmits the control signal to the motor drive module for controlling the rotation of a kitchen ventilator motor. The system is convenient, enables a user to be able to remotely control the kitchen ventilator, and can guarantee that the panel of the kitchen ventilator is ordered and smooth and is easy to clean.

Description

technical field [0001] The invention relates to a range hood control system, in particular to a range hood control system based on gesture recognition, which is suitable for remote control of household range hoods. Background technique [0002] Range hood is an important kitchen appliance for purifying residents' kitchen environment in the process of urbanization in my country. It is usually installed above, below or on the side of the stove in the kitchen, and can quickly suck away the harmful oil fumes generated during the cooking process. The range hood not only has the function of purifying the kitchen air and beautifying the kitchen environment, but also has the function of anti-virus and explosion-proof safety guarantee. For users at all levels, how to design range hoods to improve the convenience of users is a hot research topic at present. [0003] As the core of the range hood, the control system of the range hood plays a key role in improving the convenience of us...

AI Technical Summary

Problems solved by technology

Because users often have oil or water on their hands during the cooking process, frequently pressing keys will cause serious oil pollution on the keys on the panel of the range hood, and the gaps at the keys will bring some inconvenience to the user to clean the panel

Although the range hood is controlled by touch buttons, which avoids the inconvenience caused by the protrusions and gaps of the buttons, this method requires the user's hands to be relatively clean. However, when cooking in the kitchen, the user's hands are covered with oil and water. The hands may hold other ingredients at the same time, so the user must either wash his hands and place the ingredients properly to control the range hood, or control the range hood with dirty hands and then clean up, so both will cause inconvenience to the user

[0004] In order to overcome the shortcomings of contact range hood control technology, the range hood industry has introduced voice control and other non-contact range hood control technologies and equipment one after another. However, in the noisy kitchen environment, the voice recognition rate will drop. control will reduce range hood control efficiency

CN103617722A discloses "a non-contact range hood control system based on infrared technology", which uses a gesture control module to control the range hood, wherein the gesture control module includes an infrared transmitter, an infrared receiver and a micro-controller It has the following problems: 1. It is required that the infrared transmitter and infrared receiver can be integrated with the range hood. Therefore, the range hood has a great impact on the accuracy of signal acquisition; 2. Only limited gestures can be recognized; 3. Irregular gestures and the distance between gestures and range hoods will greatly limit the practical application of such technologies
