Abstract

The utility model relates to a water run-out preventing monitor which is characterized in that the utility model comprises an electrical controlled valve arranged on a water supplying pipeline, a flow meter arranged on the water supplying pipeline and a flow transmitter integrally connected with the flow meter; the flow transmitter is connected with an input end of a controller of a single chip computer; an output control end of the controller of the single chip computer is connected with a driving control circuit of the electrical controlled valve. The utility model has the basic principle that living water comprises a normal water state and an abnormal water state according to a time constant; when the abnormal water state appears (a water tap is not turned off or water leaks out of a pipeline), a flow signal is converted into an electric signal by the flow transmitter to be transmitted to the controller of the single chip computer, the signal is processed by the controller of the single chip computer, the controller of the single chip computer emits a command to lead the electrical controlled valve to be closed, and the pipeline for supplying water is cut off. The utility model has the advantages that the utility model can monitor the water run-out of the water tap and can also monitor the water leakage of other positions of the water supplying pipeline, which effectively prevents the flood damage from happening in a user's house and avoids the waste of water resources.

Description

The anti-supervising device of metalling run out

Technical field:

The utility model relates to a kind of anti-supervising device of metalling run out that is applied on the water supply pipe.

Background technology:

In life, because water swivel does not close, the floods (metalling run out) of the corrosion of water pipeline, initiation such as break are of common occurrence to loss and neighbourhood's dispute that people bring; The water waste that " perennial draingage " that forms owing to reasons such as cistern are airtight not sternly, the water swivel cushion rubber is aging brings also is to be difficult to avoid.All adopt pressure or law of buoyancy that single water swivel is controlled at present, so that the water swivel of not closing is cut off the water supply when coming water once more.But this technology can't be monitored water systems whole in the room, especially can't supervise the water pipeline corrosion outside the water swivel, the leaking of causing of breaking.

Summary of the invention:

In view of the deficiency that above-mentioned prior art exists, the purpose of this utility model provide a kind of can be to whole anti-supervising device of metalling run out of monitoring of water systems in the room.

The purpose of this utility model is achieved in that it comprises that the electrically-controlled valve and the flow that are arranged on the water pipeline take into account the flow transmitter that is connected as a single entity with flowmeter, this flow transmitter links to each other with the input end of a singlechip controller, and the output control terminal of singlechip controller links to each other with the Drive and Control Circuit of electrically-controlled valve.Its ultimate principle is with time constant domestic water to be divided into normal water and improper water two states.Time constant is meant the time that current that flow velocity remains unchanged continue, this time value can the people for setting.Normally be meant with water state: 1, the water time quite long, but show each water terminal (water swivel) should be down here, start-stop stops, therefore on flow velocity should be to neglect fast neglecting constantly to change slowly; 2, flow velocity is constant, but the water time is shorter relatively.Improper have only a kind of situation with water state, is exactly to remain unchanged with water flow velocity for a long time, surpassed the setting-up time constant.This has only may taking place of a kind of maximum, and promptly water swivel does not close or pipeline leaks.By flow transmitter flow signal is converted into electric signal and is transferred to singlechip controller, signal is handled, determine normal water and improper water by singlechip controller.When improper water occurred, singlechip controller promptly sent instruction, closes electrically-controlled valve, cut off supply channel.

Above-mentioned singlechip controller reaches the display that links to each other with single-chip microcomputer by single-chip microcomputer, analog to digital conversion circuit, D/A converting circuit, electrically-controlled valve Drive and Control Circuit and constitutes, its output terminal of analog to digital conversion circuit of connection traffic transmitter output terminal links to each other with the signal input part of single-chip microcomputer, and the signal output control terminal of single-chip microcomputer links to each other with the control motor of electrically-controlled valve through D/A converting circuit, electrically-controlled valve Drive and Control Circuit.

The utility model has the advantages that both can monitor water swivel " metals run out ", can monitor other position of water pipeline again and leak, thereby prevent that effectively the user from floods taking place, also avoided the waste of water resource.

Below in conjunction with accompanying drawing the utility model is done with explanation.

Description of drawings:

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model circuit theory diagrams.

Embodiment:

By accompanying drawing as can be known, the utility model mainly is made of singlechip controller 1 and the electrically-controlled valve 5, flowmeter 3 and the flow transmitter 2 that are located on the water pipeline 8.Sequence number 4 is for connecting the cable signal line of singlechip controller 1 and flow transmitter 2, electrically-controlled valve 5 among the figure; Sequence number 7,9 is respectively former water meter, the overhead control valve that is installed on water pipeline 8 inlets.Singlechip controller mainly comprises the single-chip microcomputer that is made of chip 8052, latch 74LS373, program storage 3732A and the display that is made of

chip

8255,7406, charactron LED and the analog to digital conversion circuit that is made of chip 14433, the D/A converting circuit that is made of chip 0832, the electrically-controlled valve Drive and Control Circuit that is made of triode BG1 and relay J, the alarm that is made of triode BG2 and hummer FQ.When user's water, measure and show the instantaneous delivery of water in the water lines by flowmeter 3, this flow signal changes electric signal into through flow transmitter 2 and is transferred to singlechip controller 1, be converted to digital signal by analog to digital conversion circuit in this singlechip controller and give single-chip microcomputer and handle (comprise timer timing, flow show), and shown by display.Exceed schedule time constant (10 seconds or 20 seconds when the constant time of instantaneous delivery, this value can artificially be set and adjust) time, send steering order by single-chip microcomputer, the instruction alarm equipment alarm shortens the cycle in sampling time, as flow in 20 seconds still remain unchanged (nobody carries out the water consumption adjustment), choose analog-digital chip 0832, the output analog electrical signal is by triode BG1 pilot relay J adhesive, and, cut off supply channel by the machine operation of the control contact of this relay control electrically-controlled valve.

To make the user can not water the time in order breaking down, at electrically-controlled valve 5, flowmeter 3 and flow transmitter 2 place pipelines are other is arranged in parallel a pipeline, and a make-up valve 6 to be set on this pipeline, make things convenient for the user with this at this device.
