Abstract
An automatic flushing device of crouch closet on the train is featured as connecting I/O input end of monolithic computer to pulse signal output end of infrared induction device, connecting I/O output end of monolithic computer to control device of pulse solenoid valve which is connected in series between pipes of water supply on the train. The device flushes 6L water for shit and 3.5L for piss depending upon time long or time short of personal body induction based on infrared induction technology.
Description
Technical field the invention belongs to the application of single-chip microcomputer in the sanitary equipment technology.
Before background technology the invention, known train squat toilet adopts foot-operated or the key mode bath is washed by water owing to not distinguishing stool and urine, cause the waste of train limited water resources,, cause pollution and the cross-infection of train with the lavatory environment as untimely flushing.
The purpose of summary of the invention the invention is intended to overcome the defective of prior art, and a kind of train squat toilet pulse magnetic valve automatic flushing device based on infrared induction is provided.
The invention solves the technical scheme that its technical matters adopts: comprise infrared inductor, single chip machine controlling circuit and pulse electromagnetic valve controling circuit, the I/O input end of single-chip microcomputer is connected with the pulse signal output end of infrared inductor, the I/O output terminal of single-chip microcomputer is connected with the pulse electromagnetic control valve device, infrared inductor is made up of infrared reception and power valve, hex inverter and phaselocked loop, finish infrared emission, reception, modulation and demodulation, the output terminal of phaselocked loop is connected with the single-chip processor i/o input end.Impulse electromagnetic valve is serially connected with between the train supply channel.Single-chip microcomputer is according to the time of secondary useful signal, and judgement stool and urine is used the lavatory state, and then the switching time of gating pulse solenoid valve, just needing by size to realize auto-flushing.Pulse electromagnetic valve coil L is connected with a pair of positive-negative-positive triode and a pair of NPN type triode respectively, four triodes are connected with the single-chip processor i/o output terminal respectively, the polarity of the output pulse by changing single-chip microcomputer changes the direction of current that flows through the pulse electromagnetic valve coil, thus the switching of driving pulse solenoid valve.Impulse electromagnetic valve is serially connected with between the train feed pipe.
The beneficial effect of the invention is: the invention is based on the infrared induction technology, time length by human body sensing is distinguished stool and urine, and replace former train squatting pan button bath or ride flushometer by 6 liters in stool, 3.5 liters of auto-flushings of urine, the beneficial effect of the invention be the conserve water resource also help train use the lavatory environment, be widely used in the control of train a new generation squatting pan.
