Abstract
The present invention discloses an automatic flushing pyroelectric inducing closet controller capable of distinguishing shit and urine for automatic flushing and relates to monichip computer application and pyroelectric control technology. The main characteristic is to install flushing solenoid valve installed in the outlet of the cistern and controlled by the CPU and to provide with pyroelectric inducing signal receiving and amplifying circuit, monochip control circuit and switch executing circuit connected successively. The present invention flushes automatically in the water amount of 6 L for shit and 3 L for urine and can save water and keep clean.
Description
Technical field patent of the present invention belongs to microchip technology field, particularly single-chip microcomputer pyroelectric sensing control technology.
Background technology patent application of the present invention a few days ago, the utility model patent 02256516.7 of having authorized except that me " can be distinguished the excrements saving toilet of flushing automatically " and adopt automatic loading water electromagnetic valve and the auto-flushing electromagnetic valve, does not have saving toilet and pyroelectric sensing control device that single employing automatic flushing valve can be distinguished the excrements auto-flushing.
The purpose of summary of the invention patent of the present invention is exactly to provide the single employing auto-flushing of a kind of energy electromagnetic valve to distinguish the pyroelectric sensing water closet control device of excrements auto-flushing, be applicable to that all kinds of water closets are distinguished excrements to be washed automatically, has both helped the conserve water resource and has also helped keeping sanitation of environment and preventing cross-infection.
Description of drawings Fig. 1 is the circuit structure block diagram of patent of the present invention.Wherein 1 is central processing unit, and 2 is water tank auto-flushing control valve, and 3 for hot type electric induction receives and control circuit, and 4 is the switch executive circuit, and 5 is power supply.

The specific embodiment
Central processing unit (1) is a 8-bit microprocessor; Water tank auto-flushing control valve (2) is impulse electromagnetic valve or general solenoid valve, is installed on the water tank water side; The pyroelectric sensing reception receives human body signal with control circuit (3) and is connected in the I/O input of central processing unit (1); Switch executive circuit (4) connects impulse electromagnetic valve by the switching tube drive circuit, and power supply (5) is Dc low voltage power supply or passes through the dc source that the rectification of civil power transformation produces.
Impulse electromagnetic valve is controlled by the impulse electromagnetic valve forward or backwards of two I/O output ports of central processing unit (1), and the coil two ends link to each other with the colelctor electrode of a pair of opposite polarity silicone tube and germanium tube respectively.
The method of attachment of impulse electromagnetic valve and single-chip processor i/o output is as follows: impulse electromagnetic valve L respectively with a pair of positive-negative-positive triode T

4Emitter stage connect power cathode.When receiving direct impulse, opens impulse electromagnetic valve, close when receiving reverse impulse, adopt general solenoid valve as electromagnetic valve, then directly by the conducting of single-chip processor i/o end by the control triode with end, and then control coupled relay or controllable silicon makes electromagnetic valve open and close.
Pyroelectric sensing receives and the S end output of control device infrared thermal release electric induced signal by probe B H in the patent of the present invention, through Fresnel lens and triode VT
1, operational amplifier IC
2Two folding and unfoldings are big, after the filtering, send voltage comparator ic
3Input 3 is compared with the reference voltage of input 2, if during human body sensing, 2 terminal voltages are less than 3 terminal voltages, comparator IC
3Output 6 output high level, then switching tube VT
2Conducting and to single-chip microcomputer output useful signal, output 6 output low levels when no human body is responded to, switching tube VT
2End.Single-chip microcomputer is according to the time of secondary useful signal, and judgement excrements is used the lavatory state, and then the switching time of control impuls electromagnetic valve, realizes just needing by size to wash by water respectively.
