Description

A kind of simple monitoring of water quality of resident's building tap water water inlet and control device

Technical field

This utility model is related to a kind of simple monitoring of water quality and the control device of tap water water inlet, especially relates to a kind of residence The water quality monitoring of tap water water inlet and control device in people's building.

Background technology

With growth in the living standard, people increasingly pay attention to tap water quality: as drinking water it is desirable to be able to contribute to Health；As life other water it would be desirable to protect skin, dress material etc..In order to protect the health of people, country formulates Extremely strict " drinking water sanitary standard " (hereinafter referred to as " standard "), tap water Drinking water quality is completely guaranteed.But During water delivery, water quality is possible to deteriorate, as resident's building of water supply tip, when aqueduct material, hydropexis Between, upstream line repair change etc., all can affect resident's building water inlet water quality；Residence especially with water tank and tank People's building, water quality is easily affected by water tank cleaning and external contamination.As the water inlet of resident's building, comprehensive water quality index prison Survey, both cannot, also there is no need.Have four big class indexs: microbiological indicator in " standard ", toxicological parameters, sensory properties with General chemical index, and radioactive indicator.Microbiological indicator and sensory properties index is wherein only had easily to be subject to water delivery process Impact, and microbiological indicator is particularly important, is related to health, therefore define in Terminal tap water in " standard " it is essential to ensure that Disinfectant residual, disinfectant therein is: chlorine, monochloro amine, ozone, chlorine dioxide.Important indicator as sensory properties It is turbidity, the water supply at initial stage after water tank cleaning and pipeline maintenance, its turbidity all can severe exacerbation.

Microbiological indicator is measured, not only loaded down with trivial details, test request condition is high, and can not possibly supervise in real time online in resident's building Survey；Though four kinds of disinfectant in on-line monitoring water can be accomplished, instrument price is high.Substantially, disinfectant is exactly oxidant, and it disappears Malicious capacity of water, can with oxidation-reduction potential (below with english abbreviation orp), data represents, and measure orp instrument low price, More much smaller than the instrument price surveying chlorine residue；Moreover, if being polluted by Organic substance during water delivery or by metal pipe-wall Corrosion contamination, causes microbiological indicator in water to deteriorate, also can show the decline of orp in water inlet.The on-line determination of turbidity compares Easily realize, when turbidity index deteriorates, microbiological indicator and other sensory properties index are all difficult to ensure that.

Therefore, a kind of easy, monitoring of practical situation of intaking for resident's building and inlet control device, for guarantee Resident's building influent quality is significant.

Utility model content

The purpose of this utility model is to provide the water quality monitoring of tap water water inlet and control device in a kind of resident's building.

The utility model proposes resident's building in the water quality monitoring of tap water water inlet and control device, by scopometer 1, the One communication output lead 2, orp measuring instrument 3, probe the 4, second communication output lead 5, single-chip microcomputer 6, power supply 7, keyboard 8, LED lamp 9, list Phase solid-state relay 10 and electromagnetic valve 11, wherein: scopometer 1 connects the input of single-chip microcomputer 6 by the first communication output lead 2, Orp measuring instrument 3 connects the input of single-chip microcomputer 6 by the second communication output lead 5, and single-chip microcomputer 6 connects keyboard 8；Orp measuring instrument 3 With probe 4；Single-chip microcomputer 6 connects power supply 7, single-phase solid relay 10 and LED lamp 9 respectively, and single-phase solid relay 10 is respectively Connect power supply 7 and electromagnetic valve 11.

The beneficial effects of the utility model are: this utility model adopts turbidity to control, and can prevent from cleaning because of water tank Initial stage water inlet with water quality severe caused by pipeline maintenance；And can according to place subdistrict position, disinfectant species, pipe network situation, According to empirical value during tap water normal supply, determine the benchmark data of orp.This device is cheap, hardware is stable, foot To ensure resident's building tap water influent quality.

Brief description

Fig. 1 is structural diagrams of the present utility model.

In figure label: 1 is transmissometer, 2 is the first communication output lead, and 3 is orp measuring instrument, and 4 is probe, and 5 is the second communication Output lead, 6 is single-chip microcomputer, and 7 is power supply, and 8 is keyboard, and 9 is LED lamp, and 10 is single-phase solid relay, and 11 is electromagnetic valve.

Specific embodiment

Combine accompanying drawing below by embodiment and further illustrate this utility model.

Embodiment 1: as Fig. 1 arranges transmissometer 1 at water inlet；And the probe 4 on orp measuring instrument 3 is arranged on residential building In space running water inlet channel, follow-up water inlet setting electromagnetic valve 11；Transmissometer 1 and orp measuring instrument are defeated by the first communication respectively Outlet 2 and the second communication output lead 5 connect single-chip microcomputer 6, model mega128 of single-chip microcomputer 6, transmissometer 1 and orp measuring instrument 3 Measured value, exports to single-chip microcomputer 6.Collection and the process of data realized by single-chip microcomputer 6, single-chip microcomputer 6 by Real-time Monitoring Data and with Benchmark data compares, thus judging whether to need to cut off entering water electromagnetic valve and implement the measure reported to the police.

Turbidity benchmark data is exactly absolute value specified in " standard ", and all real-time turbidity data are more than this value, monolithic Machine 6 all makes cut-out entering water electromagnetic valve the judgement reported to the police；The benchmark data of orp can be constant value or with the time For the functional value of variable, by drawing the ratio that orp value reduces, single-chip microcomputer 6 is made whether to cut off entering water electromagnetic valve and reports to the police Judge.Single-chip microcomputer 6 is " logic or (or) " to the logical operationss of muddy angle value and orp value as long as relation is it may be assumed that have in two indices One index can not reach requirement, all takes cut-out entering water electromagnetic valve the scheme reported to the police.
