Description
Technical field
The present invention relates to a kind of measurement instrument, definite says, is a kind of water meter of remote transmission meter reading.
Background technology
Water meter, as a kind of measurement instrument, is that the integrated flow of water is measured mostly.Generally be divided into volumetric water meter and velocity type water meter two classes, adopt the direct mechanical motion process of removable wall volumetric measurement chamber or flow rate of water flow to the work of wing wheel in order to calculate the flowmeter of current volume of the water supply pipe of flowing through, existing water meter is waterworks and is arranged on the inlet end on each user's doorway, house, traditional water meter needs staff's observed and recorded one by one, so extremely loses time; In order to address the above problem, collecting unit, short-range communication unit and related signal processing unit are set in water meter, the reading of water meter is sent on staff's handheld terminal, so, what staff just can mass obtains meter reading.The collecting unit of present water meter arranges K1 and two switches of K2, and K1 conducting is expressed as A, K1 disconnection and is expressed as
k2 conducting is expressed as B, K2 disconnection and is expressed as
needle often circles, and one of four states occurs successively:
If water forward flow (needle clockwise rotates) in remote transmitting water meter, one of four states moves by following rule:
If water reversed flow (needle rotates counterclockwise) in remote transmitting water meter, one of four states moving law is as follows antithesis:
If this kind of water meter moves in the situation that existing external magnetic field to disturb, sensor at this moment all can detect constant magnetic signal, and sensor just cannot be counted, and cannot obtain correct reading, affects staff and normally works.
Summary of the invention
Goal of the invention: the object of this invention is to provide that one is convenient to safeguard, reading is accurate, when being subject to external magnetic and disturbing can and the water meter of alarm.
Technical scheme: the present invention adopts following technical scheme to realize: a kind of three impulse sampling remote transmitting water meters, comprise water meter body and be arranged on the signals collecting conveyer on water meter body top, near a side of dial plate, arc groove is set at signals collecting conveyer, arc groove edge arranges the over cap that covers water meter dial plate, the root of described pointer arranges magnet, three pick-up transducers are set on signals collecting conveyer, in the time that pointer rotates, magnet passes through pick-up transducers successively, thereby make pick-up transducers magnetic signal be detected and conducting, and then make pick-up transducers send signal.
Described pick-up transducers comprises first sensor, the second sensor, the 3rd sensor, and three sensor settings are at the edge of device for signalling downside, and the spacing between sensor is greater than the distance of reaction of magnet.
Described pick-up transducers is magneto-dependent sensor.
The processing unit that judges water meter rotation direction is set in signals collecting conveyer, and processing unit connects pick-up transducers and also receives the signal that pick-up transducers is sent, and the priority of sending according to signal judges water meter rotation direction, and described processing unit is single-chip microcomputer.
The dismountable side that is fixed on water meter body top of described signals collecting conveyer, described fixed form is that trip connects or bolt connects.
In described signals collecting conveyer, communication unit is set, communication unit is M_BUS or RS485 telecommunication circuit, and traffic element is subject to Single-chip Controlling.
On single-chip microcomputer, connect storage unit, single-chip microcomputer is processed the signal receiving after coding, sends into after storage unit is kept in and sends.
On signals collecting conveyer, power supply unit is set, power module is single-chip microcomputer, traffic element and sensor power supply.
Beneficial effect: compared with prior art, it utilizes three pulse signals to monitor indicator of water gauge in the present invention, and its accuracy strengthens greatly; And only utilize the magnetic induction signal producing as identification signal, its algorithm is simple, clear logic, the probability of makeing mistakes is little; And signals collecting conveyer is departed from the setting of water meter body by it, it is easy to safeguard more.

Embodiment
Below in conjunction with instructions, the present invention is described in further detail:
The present invention relates to a kind of remote transmitting water meter of three pulsed samplings; comprise water meter body 1; afterbody at a root pointer 4 of water meter body 1 arranges a magnet; along with pointer 4 rotates; magnet also rotates thereupon; on the top of water meter body 1; be provided with signals collecting conveyer 2; specifically; signals collecting conveyer 2 is arranged on a side on water meter body 1 top, its some cover dial plate top and according to the shape of dial plate, one arc-shaped recess be set, at arc-shaped recess place; over cap is also set, by over cap, dial plate is covered.Arc-shaped recess place directly over the movement locus of pointer that is provided with magnet is provided with three pick-up transducers 3, be respectively first sensor, the second sensor, the 3rd sensor, in the time that pointer rotates, magnet is respectively through three sensors 3, three sensor 3 conductings successively, thereby send successively signal, the distance in the present invention between three sensors 3 is greater than the distance of reaction of magnet, so can not produce three sensors and be subject to magnet impact simultaneously and send simultaneously the phenomenon of signal.The pointer that magnet is set described in the present invention is arranged according to actual conditions, is traditionally arranged to be x0.01 times of pointer.
The signal input signal that three sensors 3 send gathers in conveyer 2 and analyzes, in signals collecting conveyer 2, single-chip microcomputer is set, single-chip microcomputer connects three sensors, and the signal of providing to three sensors respectively defines, as first sensor provides a-signal, the second sensor provides B signal, the 3rd sensor provides C signal, if water forward flow in remote transmitting water meter, needle clockwise rotates, signal is input as: A → B → C, on the contrary input C → B → A.The circulation of A-C is pointer and turns around, and single-chip microcomputer is in addition record of the number of times of signal cycle, thereby converses the flow of water in water meter, is that explanation is that external magnetic is disturbed when A, B, C detect signal simultaneously, now can produce alerting signal.
In the storage unit that the flow of the current that converse arranges in signals collecting conveyer, give record, and stamp corresponding timestamp, at set intervals, the data that newly add are just covered the oldest data, ensure that memory device normally moves, can not store and overflow.
Sensor described in the present invention is magneto-dependent sensor, in general adopts Hall element or tongue tube to be realized.
In signals collecting conveyer, be also provided with communication unit, send after request when user's handheld device, single-chip microcomputer extracts data, after encoding, sends by traffic element; Or directly obtain data by long-range GPRS access.In the present invention, communication unit is M_BUS or RS485 telecommunication circuit.
The dismountable water meter body top that is fixed on of the conveyer of signals collecting described in the present invention, described fixed form is preferably used trip to connect or bolt connecting mode, like this in the time that signals collecting conveyer breaks down, can be changed very easily, and do not need water meter to pull down completely, first reduced manually, also provided cost savings simultaneously.
