Description
Technical field
The utility model relates to a kind of measurement instrument, specifically, 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 class, adopt the direct mechanical motion process of removable wall volumetric measurement room or flow rate of water flow to the work of wing wheel in order to calculate the flowmeter flowing through the current volume of water supply pipe, existing water meter is the inlet end that waterworks is arranged on the doorway, house of each user, traditional water meter needs staff's observed and recorded one by one, so extremely loses time; In order to solve the problem, arrange collecting unit, short-range communication unit and related signal processing unit, be sent on the handheld terminal of staff by the reading of water meter in water meter, so, staff just can the acquisition meter reading of mass.The mode of present employing adds small magnet on the pointer of original old-fashioned water meter, and add a magneto-dependent sensor and outside collecting circuit board in water meter inside, sensor and outside collecting circuit board are connected by wire, it reaches the object of water measurement amount by the number of turns detecting indicators turn.This water meter is arranged on water meter inside due to foregoing circuit element, and it needs to make certain water-proofing treatment, the quotation adding water meter undoubtedly; And circuit board section and sensor part are divided into consumable accessory, need to open whole water meter during maintenance to place under repair, water meter is even needed to change completely, so wasting manpower and material resources, two waste material, and its signal transmission is by magnetic field, so just there is situation about may be disturbed by external magnetic field, at this moment sensor all can detect constant magnetic signal, and sensor just cannot count.
Utility model content
Utility model object: the purpose of this utility model is to provide a kind of water meter being convenient to safeguard, use manpower and material resources sparingly.
Technical scheme: the utility model adopts following technical scheme to realize: a kind of up-sampling is separated magnetism-free type remote transmitting water meter, comprise water meter body, conveyer is gathered in water meter top signalization, at signals collecting conveyer, arc groove is set near the side of dial plate, arc groove edge arranges the over cap covering water meter dial plate, the root of the root pointer arranged in dial plate arranges metallic conductor, signals collecting conveyer arranges two pick-up transducers, sensor is the LC free harmonic vibration damped vibraion utilizing telefault and capacitor to form, and timing gives oscillator pulses pumping signal, when indicators turn, conductor is near inductance, damped oscillation amplitude decays rapidly.
The dismountable side being fixed on water meter body top of described signals collecting conveyer, described fixed form is that trip connects or bolt connects.
In signals collecting conveyer, arrange the processing unit judging uninterrupted, processing unit connects pick-up transducers and detects damped oscillation degrade condition in pick-up transducers measures the number of turns of indicators turn, and described processing unit is single-chip microcomputer.
In described signals collecting conveyer, arrange communication unit, communication unit is M_BUS or RS485 telecommunication circuit, and communication unit is by Single-chip Controlling.
Single-chip microcomputer connects storage unit, after the signal transacting received is encoded by single-chip microcomputer, sends into after storage unit is kept in and send again.
Signals collecting conveyer arranges power supply unit, and power supply unit is single-chip microcomputer, communication unit and sensor power.
Beneficial effect: the utility model compared with prior art, signals collecting conveyer is departed from water meter body and arranges by it, easy to maintenance, and can change circuit component according to actual conditions, which save time and manpower, avoid the waste of material, and the utility model measures current volume by measuring the realization of damped oscillation time, what it was interfered may reduce greatly.

Embodiment
Below in conjunction with instructions, the utility model is described in further detail:
The utility model relates to a kind of novel remote transmitting water meter, comprise water meter body 1, at the afterbody of a root pointer 4 of water meter body 1, one piece of metallic conductor is set, along with pointer 4 rotates, metallic conductor 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 the side on water meter body 1 top, its some cover above dial plate and according to the shape of dial plate and one arc-shaped recess be set, the arc-shaped recess place on movement locus top of the pointer being provided with magnet is provided with pick-up transducers 3, two LC free harmonic vibration damped vibraions that sensor utilizes two telefaults and two capacitors to form, and timing gives oscillator pulses pumping signal, when indicators turn, conductor is near inductance, damped oscillation amplitude sharp-decay.The pointer arranging magnet described in the utility model is arranged according to actual conditions, is traditionally arranged to be x0.01 times of pointer.
The amplitude minimum value input signal of damped oscillation gathers in conveyer 2 and analyzes by sensor, in signals collecting conveyer, single-chip microcomputer is set, single-chip microcomputer connects pick-up transducers 3, one threshold value is set in single-chip microcomputer, when the time reckoning of single-chip microcomputer damped oscillation goes out the indicators turn number of turns, thus converse the flow of water in water meter.
Record is given in the storage unit that the flow of the current conversed is arranged in signals collecting conveyer 2, and stamp corresponding timestamp, at set intervals, the oldest data are just covered by the data newly added, ensure that memory device normally runs, can not spilling be stored.
In signals collecting conveyer 2, be also provided with communication unit, after the handheld device of user sends request, data extract by single-chip microcomputer, are sent after encoding by communication unit; Or directly obtain data by long-range GPRS access.In the utility model, communication unit is M_BUS or RS485 telecommunication circuit.
The conveyer of signals collecting described in the utility model 2 is dismountable is fixed on water meter body 1 top, described fixed form preferably uses trip to connect or bolt connecting mode, like this when signals collecting conveyer 2 breaks down, can be changed very easily, and do not need water meter to pull down completely, reduce firstly artificial, also save cost simultaneously.
