[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Most schools are equipped with hot water faucets, which provide convenience for teachers and students. However, children in lower grades may not be able to use the hot water faucet independently due to their young age. In order to prevent children in lower grades from accidentally opening the hot water faucet, the utility model can effectively manage the use of hot water through face recognition to achieve the purpose of safe water use. The pre-power supply design is added to achieve rapid response and recognition, and is easy to use. Touch sensing is added to the hot water switch, and early warning reminders can be added on the basis of face recognition. The utility model occupies a small area, has a small amount of engineering, is cost-effective, and has high reliability.

[0026] Figure 1-Figure 3This is an embodiment of the utility model: a face recognition automatic switch faucet for preventing scalding by boiling water, comprising a face recognition module 1 for collecting face information through a camera; a main control module 2 for establishing a control connection with the face recognition module 1, the main control module 2 adopts an integrated chip of model ESP32, the camera adopted by the face recognition module 1 is integrated on the ESP32 main control chip, in addition, ESP32 also provides WiFi, a video transmission interface, an LED control interface, and a single-chip microcomputer connection interface, etc. The main control module 2 is used to control the face recognition module 1 to collect face information, and to process the collected face information. The face recognition automatic switch faucet also includes a current control module 3 that receives the face recognition result generated by the main control module 2 and switches the current on and off according to the face recognition result. The current control module 3 uses a relay to switch the current on and off. The current control module 3 controls the switch of the boiling water solenoid valve by controlling the on and off of the current. The boiling water solenoid valve is a full copper food-grade boiling water solenoid valve; and a pre-power supply module 4 that controls the power on and off of the main control module 2. After the pre-power supply module 4 converts 220VAC to 24VDC safety voltage, it supplies power to system-related equipment. The pre-power supply module 4 The invention comprises a human signal acquisition module 41 for acquiring human activity signals through a human infrared sensor; and a power on / off control module 42 for receiving the human signal acquired by the human signal acquisition module 41 and switching the current on and off for the main control module 2 according to the human signal. The human signal acquisition module 41 adopts a human infrared sensor, and the power on / off control module 42 adopts a relay. Users can select sensors with different sensing distances according to their needs. When the human infrared sensor senses human activity, it outputs a signal to energize the relay. The relay is usually in a normally closed state, and the relay outputs power to the main control module 2 to realize pre-supply. When using the face recognition system, the sluggish feeling caused by the startup delay is avoided to achieve a quick response. When the face information collected by the face recognition module 1 is recognized by the main control module 2, a signal is sent to the current control module 3. The relay used by the current control module 3 energizes the switch of the water-boiling solenoid valve, so that the water faucet can be used normally. When the human body leaves, the human infrared sensor will output a closing signal. At this time, the power supply to the main control module 2 is disconnected, and the current control module 3 will also be powered off, so that the solenoid valve will also lose power. After losing power, the solenoid valve will remain in a normally closed state, thereby cutting off the water source and achieving the purpose of safe water use.

[0027] As the preferred technical solution of this embodiment, the face recognition automatic switch faucet also includes a tactile sensing module 5 for collecting touch signals through a tactile sensor. The tactile sensing module 5 adopts a capacitive touch sensor with model MPR121QR2. The tactile sensing module 5 is installed on the faucet switch. The tactile sensing module 5 is used to send the touch signal to the main control module 2. The main control module 2 analyzes and warns based on the received touch signal and the face recognition result. The signal generated by the user through touch is sent to the main control module 2 through the tactile sensing module 5. If the main control module 2 receives the touch signal and the face recognition is successful, it sends a signal to the current control module 3. After the relay used in the current control module 3 receives the signal, it connects the power to the all-copper food-grade boiling water solenoid valve to keep the boiling water flowing. At this time, turning on the faucet can control the water flow and the switch.

[0028] As a preferred technical solution of this embodiment, the main control module 2 includes an information acquisition module 21 for receiving the face information collected by the face recognition module 1, processing the face information, and generating face data; and an analysis and comparison module 22 for receiving the face data generated by the information acquisition module 21 and the touch signal collected by the tactile sensing module 5. The analysis and comparison module 22 is used to compare the face data with the preset data in the face recognition management system to generate a face recognition result, and analyze the face recognition result and the touch signal to generate a sensing result. The information acquisition module 21 and the analysis and comparison module 22 both adopt the built-in algorithm of the main control module 2. The face information collected by the face recognition module 1 is obtained through the information acquisition module 21, and the face information is analyzed and processed through the image processing algorithm to generate face data, which is convenient for subsequent analysis and comparison. Module 22 compares the face data with the face information registered in the face recognition management system. If the information is consistent, the recognition is successful, otherwise the recognition fails. When the touch signal sent by the tactile sensing module 5 is received, if the face recognition fails, it is considered that the current faucet is unusable. If someone touches the faucet switch and tries to turn on the faucet switch, an early warning prompt is sent to the user to prevent lower grade students from trying to turn on the faucet switch when the recognition fails, which not only damages the equipment but also may scald lower grade children due to residual hot water; and an early warning module 23 that issues an early warning based on the sensing result. The early warning module 23 uses a buzzer and an LED light for early warning. When the main control module 2 receives the touch signal but the face recognition fails, an early warning reminder is sent to the user through the buzzer and LED light of the early warning module 23.
