Overview of smart energy-saving faucet system scheme and fiber optic light design

1. Overview of intelligent energy-saving faucet system

The system is mainly composed of infrared sensing part, power generation and storage part and power consumption part. The infrared sensor of the faucet receives the induction signal, the single-chip microcomputer processes it and sends out an instruction, controls the solenoid valve to open, the faucet is turned on and waterproof, and the water flows through the turbine to generate electricity. .

1.2 Infrared sensor part

In this paper, a 52 single-chip microcomputer is used to control the photoelectric sensor. The infrared faucet control circuit is composed of a transformer, an infrared transmitting circuit, an infrared receiving circuit, a solenoid valve control circuit and a sensitivity adjustment circuit. The circuit is powered by 220V alternating current, and 12V direct current is output from the secondary side through the transformer to supply the operation of the electromagnetic water valve, the infrared emitting and receiving tube and the control circuit of the electromagnetic water valve. The relay is supplied with 5V voltage by the microcontroller. The circuit collects the external signal by the infrared transmitting and receiving tube. When the signal changes, the measured change is first converted into a change of the optical signal, and then the optical signal is converted into an electrical signal by the photoelectric element. The electrical signal is input into the electromagnetic valve control circuit, and the electromagnetic water valve control circuit controls the opening and closing of the electromagnetic valve according to the change of the input signal.

1.3 Power generation and storage part

The generator uses a F50 -12V water turbine with a DC 12V regulated output, which can charge the battery and work for the optical fiber lamp and the system. The design of the energy storage part is that the output terminal of the turbine outputs a stable DC voltage through the LM2596 voltage regulator module, and then the DC voltage is stabilized within the charging voltage range of the battery through the LM7805 charging protection module, so that the battery will not be damaged due to overcharging. damage, ensuring the safety of charging. The electric energy stored in the battery can be used by loads such as fiber optic lights and voice chip lights. Because the service time of the faucet is short, the flow through the water turbine is limited, so the power generation is limited, the battery is fully applicable, and there is no need to use a more powerful energy storage device.

2. Intelligent energy-saving faucet fiber optic light part

The fiber optic light uses the whole body fiber optic material, and uses the bright LED exposed light as the light source. The light-emitting components of the light source are made of high-brightness LED semiconductor chips, and are made with special technology and advanced design. Its special production process makes it have the advantages of easy installation of luminous characters, energy saving, cost reduction, high brightness and eye-catching colors. During the use of the faucet, the electric energy generated by the water turbine can be used for the operation of the fiber optic lamp, which plays the role of lighting and saves resources.
