Abstract

The invention relates to an intelligent water meter with function of releasing, spraying and leaking prevention. In order to solving the long-term and common releasing, spraying and leaking problems of the running water, the invention provides a technical scheme of improving existing equipment that includes the IC pre-payment intelligent water meter and an infrared induction valve and contains a microprocessor, a control program, an electromagnetic valve, an inductor, an input interface, an indicator, and a power supply and the like. According to the technical scheme, a subprogram that is used for determining whether releasing, spraying and leaking phenomena of the running water exist and controlling the on/off of the electromagnetic valve is added to the control program of the equipment; and the determination of existence of the releasing, spraying and leaking phenomena uses the technical means for determining whether continuous water flowing time or water outflow volume exceeding the normal value exists. The technical technique can be realized easily by changing the control program at the existing intelligent water meter and infrared induction valve and can be applied to the intelligent water meter or induction valve with the improved control program and better functions.

Description

The intellectual water meter of leakage is emitted in anti-race

Affiliated field: water works, has the electronic product of microprocessor.

Background technology:

Who does not commit excesses a minor error, such as forgets to turn off the light, and forgets to turn off the tap.Forgetting to turn off the light is exactly waste some electricity, and forget to turn off the tap, waste may be just larger, and also may cause unknown losses, such as, family floods.

Time-delay valve, infrared induction valve etc. has been had now to help us to make few the mistake of wasting water, although also just use in part place.

Running water pipe can burst, especially winter.Public place still needs a lot of common valve.

Recently, Tianjin government performs actual deeds for the people, and start old building transforming engineering, therefore I sees a kind of prepayment IC-card intellectual water meter.This intellectual water meter developed along pre-paying kilowatt-hour meter thinking, your tap water turned off by its meeting solenoid valve.Is leakage emitted in the race that this intellectual water meter can be utilized to realize anti-tap water so I just thinks?

Summary of the invention: the present invention emits leakage problem in order to the race solving tap water that is long-term and that extensively exist, proposes one to existing IC prepayment intelligent water meter and this kind of technical scheme a bit improved containing microprocessor, control program, solenoid valve, inductor, input interface, indicator, the isostructural equipment work of power supply of infrared induction valve.Whether the program is in the control program of this kind equipment, increase the subroutine that the race that whether there is tap water emits the judgement of leakage situation and Controlling solenoid valve to turn off, and exist to run and emit the judgement of leakage situation to be adopt to judge whether to exist to be greater than conventional constant to go out this technological means of water state.This technological means can be realized by change control program easily on existing intellectual water meter and infrared induction valve, also can be applied to that design control procedure is more perfect, the better intellectual water meter of function and sensing valve.

Accompanying drawing illustrates: Fig. 1 is the general structure schematic diagram that the intellectual water meter of leakage is emitted in this kind of anti-race.

The control program of a kind of intellectual water meter of Fig. 2 adds anti-race and emits flaw programmed logic to judge FB(flow block).

Embodiment:

How is judgement forgotten to turn off the tap, or valve where, water pipe leak? it will be argued that, forget to turn off the tap, be that the long-time excessive flow of a kind of water does well, leak, is also that the long-time excessive flow of tap water does well.That is, the intervention of people is lost.So, what kind of is when someone intervenes? someone intervenes, does people understand What for? yes closing valve.So, it is considered herein that, a kind ofly go out the time out of usual solid stream of water or current output may be just that nobody's closing valve or pipeline leak and cause, so, can realize for this situation the equipment that valve shut by programmed control solenoid valve, intellectual water meter or the valve of leakage are emitted in a kind of exactly anti-race.

The control program that Fig. 2 provides a kind of intellectual water meter adds anti-race and emits flaw programmed logic to judge flow process.

Initialization-except user buys water yield register msl, add very consumption flow accumulation register rl and delivery time time-out time accumulation register tl, and determine to control numerical value rlf and tlf, add and set up counter rld and timer tls.Beginning-chip card reader, the water consumption msld that user buys is read in customer volume register, and determining whether zero, is zero, call and close valve subroutine, turn off valve, otherwise start reading flow numerical quantity and velocity amplitude, zero? that rld, tls data are reset, and are not, rld, tls successively decrease, and then judge whether rld and tls is zero, has respectively, provide control data, start solenoid valve, Shuttoff Valve, no, return, continue to read.

Non-constant flow accumulation register controls numerical value rlf, is called for short non-constant domination number herein, can determines according to general service condition.Such as, general family, washes dish, washes clothes, and once discharge water a few liter or a few decaliter, because, the finite capacity of washing machine.Disposable discharging water may be at most bathtub, at most namely 100 liters.So, prevention number is set to such as 130 liters or 140 liters just passable.When user buys water, ask user's family maximum regimen condition, these data are implanted, or manufacturing enterprise is according to market study, even mandarin duck bathtub, once discharge water namely 140 liters, this numerical value Uniform provisions of product is just 140 liters by that, meets special circumstances and changes individually.Function is emitted in race like this with regard to realizing prevention household tap water.Be scaled flow number 140 liters, then be scaled 16 system numbers, namely obtain rlf.

Delivery time time-out time controls setting up of numerical value tlf and is mainly used in leakproof.Sometimes valve does not close and puts in place, or valve or pipeline have damage, and lavatory or toilet leak, and are sometimes not easily found, but water meter can be measured, and the time grow, and it is also not little for wasting, and this situation also more often occurs.Due to the pressure of supply water difference of tap water pipe network may be there is, tlf can be set to 60 minutes, to pressure of supply water lower can be set to 120 minutes.120 minutes are scaled 16 systems of machine cycle, namely obtain tlf.Because have rlf as criterion simultaneously, generally there will not be large waste.For the intellectual water meter of present employing IC-card, by control program Shuttoff Valve, still need with water, as long as with card induction or insertion deck, it is just passable to carry out reset operation, but should search reason, and solves as early as possible.

Use the infrared induction valve of microprocessor, above-mentioned functions will be realized completely, need to possess speed pickup to experience flow, if only only time controls, will be strictly many.The now common public place time delay infrared induction valve of several seconds, expensive, if adopt Microprocessor S3C44B0X, facilitate and be incorporated into the use of other places, and realize water saving.Such as use in kitchen, hand is close, induction water outlet, until should turn off the tap, hand is again close, closes.May exceed if discharged water continuously and wash nappy capacity, as 3 minutes, then automatically turn off valve, also not wash if thought, need hand again close, induction water outlet.Not enough for pressure of supply water, the water supply network that ductwork pressure changes greatly, uses above-mentioned anti-race to emit and leaks intellectual water meter or sensing valve, may need to add pressure transducer at the water intake end of this kind equipment, with rlf and the tlf value of calibration setup.
