Description

A kind of Mousehold water saving valve control system
Technical field
The utility model belongs to automation field, particularly a kind of Mousehold water saving valve control system.
Background technique
In daily life, when needing water at home, we need manual unlocking water tap, accumulate over a long period and can assemble a large amount of bacteriums on water tap, while fetching boiling water leading water, if direct manual unlocking switch, can be infected with on hand a large amount of bacteriums, very unhygienic.Moreover after people are finished water, closed tap in time, will cause the waste of water resources.
Had at present infrared sensing water tap, when having object blocks before infrared senor, water tap will be opened automatically, thereby has reached the function of automatic control.But at home; many times all need to discharge water to cook; manufacture hot water; people will be placed on water container below water tap, and water tap is water outlet always, if at this time have the phone sound to rise in another room; people can be eager to answer the call conventionally; and forget that water tap is still in water outlet, and water tap cannot sense whether people leaves, water overflow container causes the waste of water resources.
Model utility content
The problem existing in order to solve above-mentioned background technology, the utility model aims to provide a kind of novel household water-saving valve control system, realizes automation control and the economical environment-protective of domestic water.
In order to realize above-mentioned technical purpose, the technical solution of the utility model is:
A kind of Mousehold water saving valve control system, comprises hot radio infrared senor, infrared tube sensor, comparing unit, solenoid valve driving module and power supply.Described solenoid valve driving module comprises optical coupled switch and relay; Described hot radio infrared senor is connected respectively comparing unit with infrared tube sensor, and comparing unit is connected with the coil of relay through optical coupled switch, and the contact of relay is connected in solenoid valve loop.Hot radio infrared senor and infrared tube sensor send respectively the signal detecting to comparing unit, and comparing unit sends control command according to the testing signal receiving to optical coupled switch, then is moved by the contact of optical coupled switch control relay.Power supply is to hot radio infrared senor, infrared tube sensor, comparing unit and relay power supply.
Wherein, above-mentioned comparing unit comprises and door and 2 comparators, the negative input end of 2 comparators connects respectively reference potential, the positive input terminal of 2 comparators connects respectively hot radio infrared senor and infrared tube sensor, and the output terminal of 2 comparators connects respectively and the input end of door, and give optical coupled switch by the signal producing with door.
Wherein, above-mentioned power supply is divided into 5V DC electrical source and 12V DC electrical source, and 5V DC electrical source is to electric infrared senor, infrared tube sensor and comparing unit power supply, and 12V DC electrical source is powered to relay.
Wherein, above-mentioned hot radio infrared senor adopts HC-SR501 human body induction module, and infrared tube sensor adopts TCR T5000 sensor.
Wherein, above-mentioned optical coupled switch adopts H92B4 optical coupled switch, and relay adopts SRD-12VDC-SL-C relay.
The beneficial effect that adopts technique scheme to bring is:
(1) automatically design: due to sensor detect and water tap control all by comparing unit, automatically complete, this model utility can provide service without manually-operable;
(2) saving water resource: add that on original automatic induction tap a hot radio infrared senor, as switch control, more meets people's demand in daily life;
(3) promptness: sensor detection speed is very fast, when people enters induction region, pyroelectric infrared sensor just has output, and at this time when infrared when tube sensor has been detected to obstacle, comparing unit just can be worked immediately, controls driver module.
Accompanying drawing explanation
Fig. 1 is system architecture diagram of the present utility model.
Embodiment
Below with reference to accompanying drawing, the technical solution of the utility model is elaborated.
System architecture diagram of the present utility model as shown in Figure 1, a kind of Mousehold water saving valve control system, comprises hot radio infrared senor, infrared tube sensor, comparing unit, solenoid valve driving module and power supply.Described solenoid valve driving module comprises optical coupled switch and relay; Described hot radio infrared senor is connected respectively comparing unit with infrared tube sensor, and comparing unit is connected with the coil of relay through optical coupled switch, and the contact of relay is connected in solenoid valve loop.Hot radio infrared senor and infrared tube sensor send respectively the signal detecting to comparing unit, and comparing unit sends control command according to the testing signal receiving to optical coupled switch, then is moved by the contact of optical coupled switch control relay.Power supply is to hot radio infrared senor, infrared tube sensor, comparing unit and relay power supply.
In the present embodiment, above-mentioned comparing unit comprises and door and 2 comparators, the negative input end of 2 comparators connects respectively reference potential, the positive input terminal of 2 comparators connects respectively hot radio infrared senor and infrared tube sensor, and the output terminal of 2 comparators connects respectively and the input end of door, and give optical coupled switch by the signal producing with door.Above-mentioned hot radio infrared senor, infrared tube sensor and comparing unit adopt 5V DC power supply, and relay adopts 12V DC power supply.Above-mentioned hot radio infrared senor adopts HC-SR501 human body induction module, and infrared tube sensor adopts TCR T5000 sensor.Above-mentioned optical coupled switch adopts H92B4 optical coupled switch, and relay adopts SRD-12VDC-SL-C relay.
Workflow of the present utility model is: 5 V DC electrical source are to after comparing unit, hot radio infrared senor and the power supply of infrared tube sensor, comparator receives the signal of hot radio infrared senor and infrared tube sensor, and sends respectively signal to 2 comparators.To collect two setting values corresponding to signal sets, then setting value is converted to reference potential and gives respectively the negative input end of 2 comparators.The signal voltage value gathering when hot radio infrared senor is higher than corresponding reference potential, there is people when sensor is other, corresponding comparator output high level, when the infrared signal voltage value that tube sensor is gathered is higher than corresponding reference potential, be that sensor is while object being detected, corresponding comparator output high level, the output terminal of 2 comparators connects the input end with door again, only have when being all high level with two input ends of door, just export high level with door, by this high level signal, give optical coupled switch, the make contact of optical coupled switch control relay, solenoid valve is opened.Except this situation, with all output low levels of door, relay contact is in off state, closed electromagnetic valve.
Above embodiment is only explanation technological thought of the present utility model; can not limit protection domain of the present utility model with this; every technological thought according to the utility model proposes, any change of doing on technological scheme basis, within all falling into the utility model protection domain.
