The invention takes a selected singlechip development board as a core, designs an induction water valve control system by expanding peripheral circuits such as an infrared sensor and the like, and mainly realizes the following functions: when the controller senses that water needs to be discharged, the controller intelligently processes the required water discharge through the single chip microcomputer, drives the ultra-low power consumption pulse electromagnetic valve to open, and tap water flows out, and meanwhile, the kinetic energy of the pulse electromagnetic valve is used for generating power and charging the rechargeable battery, so that external energy is completely not needed, and the purposes of energy conservation and emission reduction are achieved.
The intelligent water output control method is intelligently embodied in the calculation of the required water output and the control of the actual water output. The water yield calculation is based on the user urine time collected by the infrared sensor and is controlled by the single chip microcomputer, and the time is counted when the user enters the sensor area and is finished when the user leaves the time. Aiming at different use time, the singlechip sends out control signals of different water flushing amount; the control basis of actual water yield is then the voltage numerical value that the generator produced, and the voltage value that produces because of the generator can be along with hydraulic big or small change in the pipeline, utilizes the AD function of singlechip, can accomplish when water pressure is great, and control water time is short slightly, and water pressure is less, then control water time is long slightly for actual water yield can be more accurate reach the requirement, avoids the condition of washing by water not enough or wasting water.
The invention has the characteristics of self-generating electricity, no external power supply is needed, in order to achieve the purpose, the device can be used for a long time, the voltages at the two ends of the rechargeable battery are introduced into the AD module of the singlechip, and when the voltage at the two ends of the rechargeable battery is detected to be lower, the water outlet time can be properly prolonged when water is discharged next time, so that the generator can generate more electric energy and store the electric energy for standby. Meanwhile, the design of the circuit and the selection of each device take low power consumption as a standard, the energy consumption of the system is reduced as much as possible, and the purposes of energy conservation and emission reduction are fully achieved.
In order to enhance the practicability of the system, a manual water valve switch is connected in parallel at two ends of the pulse electromagnetic valve, when the energy storage of the rechargeable battery is insufficient due to long-time non-use, the water valve is opened manually to discharge water, the generator can generate and store electricity by utilizing the kinetic energy of the generator, and the generator can be normally used next time. Meanwhile, the condition that the urinal cannot be used when the device breaks down is also avoided.
In the invention, the kinetic energy of the water outlet of the water valve is fully utilized by the water valve controller, and the kinetic energy is converted into electric energy for the system, so that the energy consumption of the system is reduced; meanwhile, the controller automatically adjusts the water outlet flow according to the induction time and the water pressure, reduces the water outlet quantity on the premise of not influencing the flushing effect, and achieves the purpose of water saving.
