The intelligent water-saving automatic controller

Technical field

The utility model relates to a kind of automatic control equipment, is specifically related to a kind of intelligent water-saving automatic controller that adopts microcomputerized control.

Background technology

Water resources is the common valuable property of the whole mankind, for the poor relatively lack of water big country of our such water resources, and protection water resources, using water wisely, for the descendants benefits, particularly important.But no matter widely used flush toilet in the city has the people unmanned at present, and day and night bath is continuous, and water consumption is big, wastes surprising.By common discharge, every day, water consumption was about ten tons in a water flushing tap, 1 year more than the 3000 ton of water that will pour off, and water rate is also wanted several thousand yuan, units up to ten thousand.Therefore, how effectively the control bath can make the lavatory clean hygiene, prevents the waste of water resources again, is the important topic of pendulum in face of scientific and technical personnel.

Summary of the invention

Technical problem to be solved in the utility model is: solve the problem that municipal water is flushed the toilet no Based Intelligent Control, had the people nobody and day and night to wash by water constantly, cause great lot of water resources to waste that has now; And provide a kind of can be according to flow of the people, tap size, the bath of delay time Based Intelligent Control, rationally utilize the water source, avoid waste, intelligent water-saving automatic controller that technical performance is good.

The technical solution adopted in the utility model is: this intelligent water-saving automatic controller is a core with thermal release electric infra-red ray sensing signal processor and single-chip microcomputer, the signal input part of thermal release electric infra-red ray sensing signal processor connects pyroelectric infrared sensor, the signal output part output of thermal release electric infra-red ray sensing signal processor is connected to the signal input part of single-chip microcomputer after transistor is anti-phase, the signal output part of single-chip microcomputer is connected to the transistor amplification driving circuit, transistor amplification driving circuit output connects the driving relay, relay control electromagnetism water valve, the height of single-chip microcomputer, the low level output also connects the working power end of control thermal release electric infra-red ray sensing signal processor.

In the technique scheme; the thermal release electric infra-red ray sensing signal processor is that the BISS0001 digital-to-analogue mixes application-specific integrated circuit (ASIC), its inside by operational amplifier, voltage comparator, condition comparator, state controller, time of delay timer and blocking time timer constitute.

In the technique scheme, single-chip microcomputer is AT89C1051 or AT89C2051, is 8 CMOS microcomputers of low-voltage, high-performance that the flash programmable read of atmel corp's band 1K byte of producing is write read-only memory.

The utility model utilizes existing embedded scm and pyroelectric infrared Detection Techniques to develop, ratio of performance to price height, experimental results show that, under the High-frequency Interference of 10-1000MHZ, detector still can be worked reliably, and mobile communication there is very strong antijamming capability, circuit design adopts the Single-chip Controlling bath time, and the bath time can set up on their own according to specified conditions, does not need to change hardware parameter, and is very convenient, go back the scalable delay time during setting, according to what of flow of the people, the size of water tank, the flow of bleeder cock cooperates delay time, controls one day bath number of times.The infrared spectrum principle work that the utility model discharges according to human body, when human body is movable in its range of receiving, pyroelectric infrared sensor receives the infrared energy that human body discharges, the output signal of telecommunication enters thermal release electric infra-red ray sensing signal processor BISS0001, handling the back output signal of telecommunication by BISS0001 hands over single-chip microcomputer to handle again, the time of water valve is opened or turn-offed to Single-chip Controlling, so just having changed in the past, no matter flush toilet has the people unmanned, the continuous phenomenon of day and night washing by water, avoided waste, the water-saving result urinal can reach more than 94%, and closet stall can reach more than 82%.

The utility model is simple in structure, and is reasonable in design, and intelligent degree height is convenient for installation and maintenance, need not change existing facility, reliable operation, long service life, high in technological content, saving water and energy, is the ideal product that substitutes touch, audio-switch, should vigorously promote the use.
