Description

Intelligent fixed quantity water meter

The present invention relates to a kind ofly can quantitatively control confluent, especially metering be can the convection current water amount detect and electric energy, mechanical energy need not to add and quantitative automatic shutoff, the certain electric signal that input is transmitted by integrated network such as IC-card, telephone communication network, wideband information net or information carrier, the micromotor in the startup table of after identification, having ready conditions again, open valve in the water meter, resume water supply; And water meter lid, watchcase, valve, valve opening closing control system, circuit locking in the water meter can be fastened as one, even water pipe head before the water meter can be hidden sealing or semiclosed from the top, locking fastens as one in the water meter, thereby prevents that non-water supply management maintenance personal from opening or dismantling the intelligent fixed quantity water meter of water meter, water meter lid, valve cover, electrical equipment box voluntarily.

At present, public water meter, be by the water strainer in the water meter housing, impeller box, spiral type or rotary wind type impeller Measuring and testing modes such as (or) rotations of measuring cup piston, gear counter, gearcase, numeral shows compositions such as wheel or pointer watch dial, water meter is serially connected with on the supply channel, current enter water meter through pipeline, pass through water strainer, enter impeller box from tangential direction, promote impeller (or measuring cup) rotation, drive multistage counting gear rotation counting, be in " power " difference of counting gear on gear set or the character wheel group diverse location or character wheel representative, represent different measurement units, character wheel or dial plate pointer are promptly represented the reading of discharge.In order to prevent that other people from taking off the water meter lid voluntarily, touch other part in the table, cause the reading variation or detect error in dipping greatly, adopt the lead sealing mode that water meter lid and watchcase are enclosed in together.But these water meters show the function of measuring of integrated flux reading and instantaneous delivery size owing to only have the metering of detecting, and water meter can only water measurement and do not have control by, the control and management function of turn-offing current.Among a small circle, little water unit turn-off, open the control of water supply and management function can only by user, supvr all can random movement the valve that adds finish, the supvr has more management method of controlling unlike the user.Some also break the credit lead sealing voluntarily, unlatching table lid is touched part in the water meter, water meter is lost detect function of measuring and correct reading accurately, do not have the credit formula lead sealing of strong equipment guarantee, and in fact incessantly some are subjected to the hand of interests driving to pipe.Simultaneously, because the variation of dwelling house, the variation of social environment, the variation of physical environment is strengthened management, water-saving requirement, and registers one's residence that the counting cost by gas meter problem increases, difficulty increases; Build the requirements of the times of an a water-saving society, and the policy guidance of country, also require the meterage water meter in a family, to read the ammeter directly, meterage is to the family.In order to adapt to or to satisfy these variations and requirement, the present small diameter watermeter that extensively generally uses in family, unit etc. is incited somebody to action from the indoor open air that moves in some places or city, but water meter is from the indoor open air that moves to, supply channel building improvement project amount is big, expense height, and destroy the finishing and the structure in house, and cause that the manual management of manual metering, meter reading personnel troop expand, efficient is low, the human error is many, and is backward in management; In the place of cold, also can not carry out the outdoor transformation of such water meter, because cold will be freezed water system, cause supplying water and interrupt.

At present existing many types by water meter and the valve that can turn-off/open, and control the new water meter (being commonly referred to intellectual water meter) that the mechanism of this valve working combines, this class new water meter is to obtain metering signal from metering water meter, use the electric detecting technology of non electrical quantity, the mechanical action of non electrical quantity is converted into electric quantity signal, and water meter is connected by signal wire with control gear; Check differentiation, by-pass valve control work through control circuit after obtaining signal.Valve can be various electrically operated valves such as the ball valve, stop valve, ceramic valve, gate valve of solenoid valve, pilot valve or Motor Control.But the new water meter of this class composite set exists on many structures, on the principle, in the use or managerial problem: the signal wire of connection, and magnetic, electric control mechanism etc., easily by people's malice or deliberately change signal and out of control with various destructions such as magnetic, electricity or machinery or other modes, or the out of control and misoperation because of damage; Some this class water meter protects signal wire and inner structure with external structures such as shell, pipelines, but still uses credit lead sealing sealing or mechanical lock to carry out locking; Can not prevent that so still some from destroying lockset, private and tearing lead sealing open, open water meter and touch part in the table, cause not measuring or measure less or measure inaccurate; For example: some this class device uses solenoid valve, owing to use the control of powered battery and low-voltage weak current, the solenoid valve adjustment is operated in highly sensitive state, misoperation occurs when, battery loose contact undesired at power supply or non-transformer, it is undesired to occur unexpected error action and metered water supply when causing the water meter valve working; This class is used the water meter of solenoid valve, also take place because of water supply line vibration, water hammer or artificially weight knock malfunctions such as water pipe water meter and valve; Some this class device uses motorized valve, and the gear of motor, connection, motorized valve bayonet socket etc. has just become target of attack, and stuck by foreign matter when bayonet socket, reduction gearing etc., device is out of hand and management function; Also as easy as rolling off a log attack of motor and transfer wire thereof destroyed; The intellectual water meter of present stage and remote transmitting water meter, have simultaneously that electronic digit shows and mechanical digital shows, such two kinds of demonstrations or multiple demonstration water consumption output, violate national measurement Law and require same measurement instrument that the legal requirements of a kind of mete-wand, a measurement standard can only be arranged; In use also be irrational: when paying is based on electronic data, the control water supply used water also is an electronic data, and the measurement standard and the reading of checking meter then are as the criterion with mechanical reading, obviously violate convention, and is obviously just out of control in actual the use; Because after using this class new water meter device, the supvr will implement the non-counting cost by gas meter of registering one's residence to the water meter measurement counting cost by gas meter to the family, the daily inspection of checking meter of no longer registering one's residence of supvr, and user (user) used under the supervision and management condition in long-term the shortage relatively, if water meter is taken off without the metered water supply water, or open the shell of this class device and water meter lid voluntarily, and change metering method or do not measure, also more easily accomplish; The composite set intellectual water meter of this class band valve that has for fear of above-mentioned because of using solenoid valve, motorized valve and battery supply and device systems defective or the deficiency brought, use resonance power supply or external power supply power supply, the non-transformer of intellectual water meter own, remote control is opened the water meter valve and is supplied water, but such water meter that has must manually be opened the water meter valve specially, when opening water meter except giving telepilot or controller packed battery, the dress IC-card, have use a teleswitch or controller simultaneously even also need to go just can open metered water supply by the respective keys of water meter with hand, use very inconvenience; In addition, the daily management of water meter controller or telepilot also is a problem; The water meter that has is attacked from the high voltage of information transmission contact in order to prevent, adopt light----electric coupling mode to transmit water supply used water information, but still have many power issues or fault of construction that source information equipment produces because of power supply: equipment do not have power supply or power supply undesired just can not be normally, stablize, reliably working! Even (top quality battery also the catastrophic failure phenomenon can occur in useful life in the phase, is commonly called as battery sudden death rate) causes equipment failure and water supply mismanagement.Therefore, this is a link of easily being attacked, or cause can not be reliable and stable the weak link that supplies water of management.If purchase only valve of opening and closing of water, then valve may because of long-term supply water be failure to actuate cause incrustation too much move ineffective, be not closed completely; Can not satisfy national requirements and implement the policy requirements of progressive price for water.The system defect of these equipment or the fault of construction of essence have formed new management hidden danger on the contrary, exist the risk that management control difficulty increases even cause mismanagement; Therefore do not reach the purpose of management control yet, increased maintenance workload all the better, and caused worry water meter operate as normal and water supply mismanagement to water meter self; And the water user uses inconvenience, and cutting off the water without reason influences user's normal life, causes problems such as bad social influence.Give the new parameter of management counting cost by gas meter reform more having increased that supplies water; This device that has still will change existing water supply line when install changing and substituting existing water meter, building improvement project amount is big, and improvement expenses is big; At present, remote transmitting water meter is being used in many places, this is to change the water measurement mechanical signal of non electrical quantity into electric quantity signal, and teletransmission is gathered or non-concentrated collection point to set of signals, but, when these teletransmission electric signal are supplied with at the circuit non-transformer, or power supply can not reliable and stable work when undesired; And, signaling point easily by magnetisable material disturb, transmission line is also destroyed easily or disturb, and causes reading error or inaccurate, in actual the use, as charge according to the time still need and often manually check, as management and control according to the time just made mistakes easily.Simultaneously, the table of these remote transmitting water meters and intellectual water meter lid, electrical equipment box, enclosing cover also can only the lead sealings of credit formula.Usually, what the telemetering type water meter was realized is the reading of checking meter of water meter measurement data, and intellectual water meter is realized is the flow through meterage of the water yield of water meter.In brief, at this stage, still lack and to take off electricity work, highly stable, reliable, anti-this class device of attacking.General knowledge is told us: if attack equipment and getting profit from attack, and the interests that obtain are greater than paying of attacking, and then attack to have long-term possibility; If attack the loss of equipment or risk, even have only loss and do not have gained much larger than gained, then attack take place may be just few, As time goes on, then equipment possibility under attack is just more and more littler.Rational management configuration to water resource, water resource lacks or the water supply management in area in short supply relatively and lack of water season and modern property water supply information system management, running water, water rate are in arrears with, are disputed over trifles etc., particularly necessity management among a small circle, little water unit that feedwater is supplied water all lacks effective, necessary management control and executive means.

Purpose of the present invention provides a kind of stable, reliable, anti-attack, may command, can take off the information-based water meter of electricity work; Be that performance is more perfect, structure is simple, control is reliable, easy to use, management is relieved, transform to install and change easily, cost adapts to corresponding the economic development management and the level of consumption in period; Water and electricity supply alternative expression work: when normal water supply, do not use power supply, also can finish when non-transformer or power supply are undesired purchasing or set the output supply, and automatically shut down valve in the water meter, use novel intelligent fixed quantity water meter, the novel teletransmission type intelligent fixed quantity water meter of power supply when only needing in collecting water rate, unlatching table valve.It can not only be the network off line terminal of IC-card as intellectual water meter the time, also can be as the teletransmission type intelligent fixed quantity water meter of having ready conditions and controlling when regional water supply management or zonule water supply centralized management.It can not only detect metering, adopts single mechanical indicator/digital character wheel to show the big or small and integrated flux reading by the instantaneous delivery of water meter, and can quantitatively control the water yield that flows through water meter; Water volume that can be utilized that can also display water-meter; Solved the fault of construction that existing intellectual water meter and remote transmitting water meter have electronic digit shows and mechanical digital shows two demonstrations or multiple demonstration water consumption, output simultaneously; Encrypt locking from water meter inside to valve, valve opening shutdown system, control circuit etc. in water meter lid, the table, and water pipe head before the water meter can be hidden sealing or semiclosed from the top, prevent that the non-management maintenance personal from opening water meter lid, valve cover voluntarily, touch part in the table, or after opening water meter lid, valve cover, change meter reading voluntarily, water pipe head before dismounting water meter, electrical equipment box, the water meter; If attack: ruin power supply, dismounting circuit, destroy structure etc., water meter supply once not need any electric energy or external force to stop water supply with regard to automatic-closing valve after quantitative, the attack obvious damage assailant oneself; Property or living facilities to oneself are carried out destructiveness and are attacked, and have only loss and do not have income, under normal circumstances also can not take place; Therefore has high anti-aggressiveness.And the extremely short start-up time that only valve supplies water in opening water meter, when maybe needing to open water meter lid, valve cover maintenance, control circuit just energized uses battery.When valve shutoff, circuit supply, use information carriers such as IC-card, telephonic communication line, wideband information net to water meter control circuit input optional network specific digit electronic signal, after the identification of water meter control circuit, can resume water supply by automatic conditionally control executing mechanism unlatching water meter valve, or open water meter lid, valve cover maintenance.Be reached for and run feedwater water supply, rational allocation use water resource, using water wisely, protection environment well; slave unit, technical thorough solution water rate are in arrears with, are disputed over trifles; for doing modern estate management well and realizing the informationization of water supply toll administration, computerize, provide the executive means of powerful effectively management, control.

The present invention is achieved in that in water meter housing, water strainer is enclosed within the outer water meter inlet end of impeller box, the end of the spiral shell wing or rotary wind type impeller connects gear (No. 0 counting gear), or the end of measuring cup piston connects gear (No. 0 counting gear), mesh together with the counting gear group in the gearcase, with in the counting gear group at the counting gear of specific gauge position, be set at the quantitative gear of counting of the quantitative amount of corresponding water supply, the quantitative control breach of cycle control during the position of counting the as close as possible gear axis of quantitative gear is provided with and is convenient to rotate, with the clutch inclined-plane, valve is arranged in the water meter, by motor through reduction gearing, control gear supplies water after driving Open valve, and the energy of exporting during with the motor Open valve is deposited with in the displacement process of magnetic material, the store energy of exporting in the time of also can be with this motor Open valve is in the distortion of spring, as the energy of valve-off; Intelligent fixed quantity water meter is under uncontrolled normal condition, and valve is swung to automatically and closed; In water supply process, drive the rotation of water meter counting gear group by the current of the water meter of flowing through, after water meter had supplied to set the water yield, little power of counting quantitative gear generation acted on valve control system by quantitatively controlling breach and clutch inclined-plane, discharge and close the valve energy, thereby close water supply valve automatically.Count the control gear of valve closing in the quantitative gear mesh control water meter/open and implement the dual control of atomic power: the one, cutting-off valve connects with the engagement of motor and reduction gearing, the 2nd, the energy of release control system valve-off is reliably closed valve when the setting output is finished; The one-directional rotation of the quantitative gear of counting repeats to press and leave roof pressure position and control position to control gear automatically in water supply process, repeats thus quantitative water supply is opened---close each take turns cycle control; And in the Open valve process, motor and train of reduction gears and control gear are linked together automatically, and finish the action of Open valve; The power supply of basic control circuit and motor after finishing Open valve with automatic cutout; And valve is started working closed again connection of power supply of control circuit when turn-offing automatically; Control circuit is after energized is started working, according to condition (for example water rate is paid situation) the decision motor of the Open valve of the setting Open valve of whether switching on.-motor, train of reduction gears, the quantitative gear of counting, control gear, valve, spring etc. are all installed and are placed in the airtight valve box that is solidified as a whole with water meter.Open water meter lid and valve box after the lead sealing, the locking closure device has been installed in order to prevent that the user from destroying, the locking in addition from water meter inside, the locking closure device is identical with general electric opening lockset principle.Is one with watermeter shell fastening locking internally with the dead bolt of tongue spring with lock with the water meter lid or the valve enclosing cover of groove with lock.As if there being two places need distinguish locking (for example water meter lid and valve enclosing cover), for simplified structure, water meter lid on the water meter shell or valve enclosing cover be a locking one place just, and another is in the preceding fixedly locking of going ahead of the rest of locking.The concrete practice is: water meter lid or valve enclosing cover or single water meter have covered locked groove outward, and the locking closure hole is arranged on the water meter housing, reach the locking closure device of being made up of jointly dead bolt hook, latch bolt spring, dead bolt shell or dead bolt frame; Dead bolt puts in the locking closure hole, and the water meter shell is fixed on cover lock.Another is in the preceding fixedly method of locking of going ahead of the rest of locking, be should locate water meter lid or the valve enclosing cover is installed on the watchcase, porose on the watchcase, put into the hole with screw or pin it is blocked, again valve enclosing cover or water meter are covered spinning on watchcase, dead bolt springs into automatically in the watchcase locking closure hole and gets final product; Also can adopt the valve enclosing cover or the water meter cover lock that will be positioned at the top to close, and the water meter of top lid or valve enclosing cover are pushed down the water meter lid or the valve enclosing cover of below, finish the locking at another place in such a way.And uncap eccentric wheel or the camming action of uncapping in the valve box or on the reduction gearing in the water meter lid can be opened the locking closure device in the dead bolt hook.Micromotor is controlled by control circuit, and the Based Intelligent Control basic circuit that with microprocessor or microelectronic circuit functional block serves as main formation is contained in the valve box, or is contained in the electrical equipment box shell that is solidified as a whole with the water meter shell after moisture seal is handled.In different wet types or dry-type meter, valve box, electrical equipment box and measurement gear box can be a common box body, or use different box bodys with: the shared box body of valve positioner and control apparatus for example.The water meter intelligence control circuit has cryptographic check, reduces water rate and controls the function that micromotor is just changeing two kinds of mechanical actions of counter-rotating, i.e. the function of Open valve and unlatching locking closure device.When valve was in opening, the output signal of position switch was cut off the electricity supply, and part or whole circuit can quit work; Work as valve closing, position switch is energized again, control circuit is started working again, control circuit is through cryptographic check etc., produces the once metering signal of deducting fees, and sends the Open valve instruction after exchanges data is confirmed to deduct fees, Open valve behind the motor start-up, position switch is cut off the electricity supply automatically behind the valve opening, the water meter normal water supply, and quantitative water supply begins again.This is the pattern of a kind of control circuit and the work of valve water supply alternative expression: power supply is necessary when Open valve only, behind the valve opening in the water supply process, the basic circuit deenergization is no longer powered, this water meter is after setting water yield supply and finishing, need not power supply can turn-off valve automatically, valve turn-offs simultaneously that position switch closes the basic circuit power supply again automatically, whole water meter be in long-time water supply but need not to power, instantaneous power supply charge opens the such working method of valve.When needs were implemented progressive price for water, the record that needs duration of valve opening was as the foundation of calculating stepped water pricing, and the water meter intelligence control circuit should have clock circuit and supply with the interior battery of micropower that clock circuit consumes.There is power work pilot light and the no water rate alarm lamp light that starts the back short-term operation in the integral sealing circuit block outside of control circuit.The card form digital integrated circuit (being commonly called as Contact Type Ic Card or non-contact IC card etc.) that the present invention adopts, or telemetering type centralized management control mode all are as information or the secret wherein a kind of carrier that transmits of instruction.For example, adopt quota decrement mode or claim the attribute IC-card, each data storage cell is represented the digit of an application, and the value of each digit is represented once quantitatively amount and corresponding actual value thereof.Suppose quantitatively once to supply water 1 ton, water unit price per ton is 1 yuan in first stepped water pricing, and then each data storage cell is worth 1 yuan.Start each time and promptly deduct 1.All water supply data, comprise that the date, time of output, Open valve, possible fees for water supplied etc. are taken back by IC-card or teletransmission communication lead is sent central water supply back to and sold the water computing machine, focus on, the circuit of each water meter and the topworks of Open valve, only part is analogous to an electronic lock.During use, with valve closing, the good intelligent fixed quantity water meter of table cover lock is installed on the user pipe, load onto battery, the IC-card that uses is injected the IC-card seat, contactless IC card must be near the relevant position, or connection connection, pass through supervisory computer by water supply person, modulator-demodular unit circuit in water meter is sent out valve water supply encrypted message, through cryptographic check, exchanges data and affirmation start micromotor in the water meter after reducing water rate, through multi-stage speed-reducing gear drive control gear, in the driving process, control gear and control gear core are one by the control gear pellet shot from a slingshot at the marble spring effect second line of a couplet, motor and reduction gearing drive the magnet control arm by control gear and control gear core, the magnet of magnet control arm acts on the magnetic guiding valve, and by lever drives glue valve, Open valve supplies water, and outage automatically, this process will be opened the required energy of valve simultaneously and be deposited with in the displacement of magnet; In the water supply process, counting quantitative gear discharges gradually in metering is rotated with self small quality and closes the valve energy: compressing center, clutch inclined-plane control lever, the center control lever ejects the control gear pellet shot from a slingshot gradually by steel ball, be subjected to magnet on the magnet control arm there is a natural attraction between the sexes effect, control gear and control gear core are thrown off, the control gear core rotates a low-angle to closing the valve direction under there is a natural attraction between the sexes acting force effect, continue in the water supply process, count quantitative gear rotation, the clutch inclined-plane leaves, the center control lever upwards reverts to previous status under the control lever spring action of center, control is next time carried out in preparation; The control fork is because of being controlled the effect of gear core to the magnetic force that closes the valve direction, act on the quantitative gear shaft of counting after this power of control gear core cap is reduced into N/one (ratio of the length arm of control fork), quantitative breach on the quantitative gear shaft of counting goes to control fork place, the control fork rotates, discharge the control gear core, there is a natural attraction between the sexes for the magnet on the magnet control arm that is solidified as a whole with the control gear core and the magnet of magnetic guiding valve, by lever transmission glue guiding valve with valve closing, once supply water and finish, the magnet control arm closes the position of source switch simultaneously, the control circuit power connection begins quantitative water supply process next time.

Whenever a quantitative water supply is finished, power on circuitry, IC-card is at IC-card seat slot, or contactless IC card does not leave induction reading zone, it normally is that data storage cell has and can supply water (water rate enough or in allowing the overdraw scope) in the normal and IC-card of powered battery that power supply detects, control circuit all will automatically carry out once Open valve job procedure again, finish and open the valve supply water process again.When needs are opened Water meter cover or valve cover, to water meter inner control circuit input boiling water table lid digital and electronic encrypted message, start micromotor, uncap cam or the eccentric wheel that drive the reduction gearing final stage are to dead bolt maximum eccentric position, dead bolt is withdrawed from locked groove in Water meter cover or the valve cover, can will show lid or valve cover with instrument and take off and carry out maintenance activity.

If when using as the teletransmission intellectual water meter, physical construction is basic identical, difference only all links together with the central control room (CCR) of lead and centralized management at the circuit of all intellectual water meters, circuit purchase surplus water, circuit functions such as inquiry surplus water all can no longer be provided with, paying the fees deducts fees concentrates in together and carries out, the management of the information management of IC-card and water charge is reduced to more single feed pipe water toll administration: the water meter circuit is accepted the instruction control of central control room (CCR), central control room (CCR) is behind the water supply requirement (closing of circuit in the water meter) that the circuit of accepting arbitrary water meter sends, central control room (CCR) through the water rate remaining sum relatively, deduct fees, send out the valve cipher instruction to the water meter circuit, open the valve process just with aforementioned identical.

Owing to adopt such scheme, can in normal water supply, implement quantitatively control, and resume water supply again easily at any time, prevent non-management maintenance personal unlatching table lid.Realization to the reasonable disposition of water resource and to supply water among a small circle, the effective and necessary management control of little water unit; strengthen using water wisely; the protection environment, the phenomenon generation of being in arrears with and disputing over trifles of stopping water rate realizes intelligent, informationalized water supply toll administration.

The invention will be further described below in conjunction with drawings and Examples.
