Description

Technical Field

[0001] The invention belongs to the technical field of energy saving, and in particular relates to an induction faucet and a control method thereof. Background Art

[0002] Traditional faucets are often opened or closed manually, so it is inevitable that people will forget to close the faucet or the faucet will not be completely closed, which will not only cause a certain amount of water waste, but also bring a certain risk of flooding. Therefore, how to control the water flow of the faucet has become a technical problem that needs to be solved urgently.

[0003] In order to realize the water flow control of the faucet, the existing technical solutions in the invention patents CN201811569845.7 "Microwave measurement method, electronic device and storage medium of induction faucet" and CN202110602469.2 "Faucet water flow control method and faucet" use infrared sensing devices to identify the user, and control the water flow of the faucet according to the identification result, which ensures the energy saving of the faucet and avoids unnecessary waste of water resources. However, at the same time, there are the following technical problems:

[0004] Due to differences in usage habits among different users, there are certain differences in the usage time of faucets among different users. In life, there is often the problem of the water flow time of the faucet being too long or too short. Sometimes it even takes two or three times of sensing to complete the use. Therefore, if the water flow control time cannot be differentiated according to the user's usage habits, it is impossible to meet the user's usage needs while ensuring energy-saving effects.

[0005] In view of the above technical problems, the present invention provides an induction faucet and a control method thereof. Summary of the invention

[0006] To achieve the purpose of the present invention, the present invention adopts the following technical solutions:

[0007] According to one aspect of the present invention, a method for controlling an induction faucet is provided.

[0008] A method for controlling an induction faucet, characterized by comprising:

[0009] S1 determines the identity matching degree with different preset users based on the infrared sensing signal of the infrared sensing window of the induction faucet, and determines whether the identity recognition reliability of the induction faucet meets the requirements based on the identity recognition matching degree. If yes, proceed to step S3, if not, proceed to the next step;

[0010] S2 determines the comprehensive identity recognition reliability of the induction faucet by the identity recognition reliability of different historical recognition times of the induction faucet within a preset time, and when the comprehensive identity recognition reliability of the induction faucet meets the requirement, proceeds to the next step;

[0011] S3 determines the suspected credible identification user among the preset users, and when it is determined that the identity result of the suspected credible identification user is unreliable through the identity identification matching degree of the suspected credible identification user and the deviation amount of the identity identification matching degree with other preset users, proceeds to the next step;

[0012] S4 takes a preset user whose identity recognition matching degree is greater than a preset matching degree as a candidate reference user, and determines the water flow control time length of the induction faucet according to the matched water flow control time lengths and identity recognition matching degrees of different candidate reference users.

[0013] A further technical solution is to determine the identity matching degree with different preset users, specifically including:

[0014] The distribution of feedback time of infrared sensing signals of different parts of the target user is determined according to the infrared sensing signals, and the matching degree between the infrared sensing signals and the identities of different preset users is determined according to the distribution of feedback time of infrared sensing signals of different parts.

[0015] A further technical solution is that the different parts of the target user include palms and fingers of the target user.

[0016] A further technical solution is that the value range of the comprehensive identity recognition reliability of the induction faucet is between 0 and 1, wherein when the comprehensive identity recognition reliability of the induction faucet is greater than a preset reliability threshold, it is determined that the comprehensive identity recognition reliability of the induction faucet meets the requirements.

[0017] A further technical solution is that, when the comprehensive identity recognition reliability of the induction faucet does not meet the requirements, the water output control time of the induction faucet is determined by a preset control time.

[0018] A further technical solution is that, when the identity result of the suspected trusted identification user is reliable, the water flow control duration of the induction faucet is determined based on the matched water flow control duration of the reference identification user.

[0019] On the other hand, the present invention provides an induction faucet, which adopts the above-mentioned control method of the induction faucet, and is characterized by specifically comprising:

[0020] Matching evaluation module, reliability evaluation module, identity result verification module, duration control module;

[0021] The matching evaluation module is responsible for determining the matching degree with different preset users based on the infrared sensing signal of the infrared sensing window of the sensing faucet;

[0022] The reliability evaluation module is responsible for determining the comprehensive identity recognition reliability of the induction faucet through the identity recognition reliability of different historical recognition times of the induction faucet within a preset time;

[0023] The identity result verification module is responsible for determining the suspected credible identification user among the preset users, and determining whether the identity result of the suspected credible identification user is reliable through the identity identification matching degree of the suspected credible identification user and the deviation amount of the identity identification matching degree with other preset users;

[0024] The duration control module is responsible for selecting a preset user whose identity recognition matching degree is greater than a preset matching degree as an alternative reference user, and determining the water flow control duration of the induction faucet according to the matched water flow control duration and identity recognition matching degree of different alternative reference users.

[0025] The beneficial effects of the present invention are:

[0026] 1. The infrared sensing signal of the infrared sensing window of the induction faucet determines the identity matching degree with different preset users, realizing accurate evaluation of the identity matching with the preset users from the perspective of infrared sensing signals, laying the foundation for the differentiated determination of water output control time, and also reducing the emergence of technical problems with high transformation costs caused by unnecessary hardware investment.

[0027] 2. The water flow control time of the induction faucet is determined according to the matched water flow control time and identity recognition matching degree of different alternative reference users, thereby realizing the adjustment of the water flow control time of the induction faucet without an accurate matching user. This takes into account the differences in requirements for the water flow control time of the induction faucet caused by differences in identity recognition matching degrees of different alternative reference users, and realizes accurate control of the water flow control time of the induction faucet by comprehensively considering the water flow control time of different alternative reference users.
