The speed measurement module 5 is used to measure the water speed. The speed measurement module 5 includes a rotor, a magnet, a power supply VCC, a Hall sensor HS, a resistor R3, a resistor R4, a resistor R5 and a transistor Q2;

[0030] The rotor is installed in the valve, the magnet is fixed on the rotor, and the Hall sensor HS is installed near the rotor. The Hall sensor HS is used to measure the rotor speed. The first end of the Hall sensor HS is connected to the power supply VCC, and the second end of the Hall sensor HS is grounded. The output end of the Hall sensor HS is connected to the first end of the resistor R4, the first end of the resistor R3 is connected to the power supply VCC, the second end of the resistor R3 is connected to the first end of the resistor R4, the second end of the resistor R4 is connected to the base of the transistor Q2, the first end of the resistor R5 is connected to the power supply VCC, the second end of the resistor R5 is connected to the collector of the transistor Q2, the emitter of the transistor Q2 is grounded, and the second end of the resistor R5 is also connected to the input port of the main control module 1. When the magnet rotates, the direction and intensity of the magnetic field around it will continue to change. The Hall sensor HS is installed near the magnet. The Hall sensor HS will generate a corresponding Hall potential according to the change of the magnetic field. By processing and analyzing these signals, the rotation speed of the magnet can be obtained, and ultimately the water speed can be obtained.

[0031] In this embodiment, a display module 2 is further included. The display module 2 is signal-connected to the main control module 1 and can use a common LCD display screen. The displayed data includes real-time water speed, set water speed and other data.

[0032] Specifically, the water discharge module 4 includes a resistor R1, a resistor R2, a transistor Q1 and a solenoid valve;

[0033] The first end of the resistor R1 is connected to the output port of the main control module 1, the second end of the resistor R1 is connected to the base of the transistor Q1, the first end of the resistor R2 is connected to the power supply VCC, the second end of the resistor R2 is connected to the second end of the resistor R1, the emitter of the transistor Q1 is connected to the power supply VCC, the collector of the transistor Q1 is connected to the first end of the solenoid valve, and the second end of the solenoid valve is grounded. The transistor Q1 is a PNP transistor. When the base of the transistor Q1 is at a low level, the solenoid valve works, and when the transistor Q1 is at a high level, the solenoid valve does not work.

[0034] Furthermore, an alarm module 6 is included, which includes a resistor R6, a resistor R7, a transistor Q3 and a buzzer;

[0035] The first end of resistor R7 is connected to the output port of main control module 1, the second end of resistor R7 is connected to the base of transistor Q3, the first end of resistor R6 is connected to power supply VCC, the second end of resistor R6 is connected to the second end of resistor R7, the emitter of transistor Q3 is connected to power supply VCC, the collector of transistor Q3 is connected to the first end of buzzer, the second end of buzzer is grounded, transistor Q3 is a PNP transistor, when the base of transistor Q3 is at a low level, the buzzer works, when the transistor Q3 is at a high level, the buzzer does not work, when the speed measurement module 5 detects abnormal water speed, the alarm module 6 will work to remind the user to check the problem in time.

[0036] When the intelligent Internet of Things valve faucet control valve of the present invention is in use, the main control module 1 outputs a PWM signal to control the water discharge module 4, thereby realizing the control of the water flow size. The water flow impacts the rotor, the rotor rotates, and the magnet rotates accordingly. When the magnet rotates, the Hall sensor HS generates a Hall potential, and the Hall sensor HS then converts the Hall potential into an alternating electrical signal. Finally, the built-in circuit of the Hall sensor HS adjusts and amplifies the signal, outputs a rectangular pulse signal, and then outputs a square wave pulse signal through the conduction and cutoff of the transistor Q2. The main control module 1 can calculate the rotor speed and then obtain the water speed, and then adjust the PWM signal to achieve precise control of the water speed. PID control can be used. In addition, when the speed measurement module 5 measures an abnormal water speed, it indicates that there is a problem with the valve or water pipe. The main control module 1 controls the alarm module 6 to issue a warning, which is convenient for the user to check the problem in time. In addition, the display module 2 can display data such as water speed in real time, which is convenient for the user to view. The user can also issue control instructions through the communication module 3, which is more practical.
