Technical scheme: the utility model adopts following technical scheme to realize: the separated magnetism-free type remote transmitting water meter of a kind of large pointer up-sampling, comprise water meter body, in water meter top signalization, gather conveyer, at signals collecting conveyer, near a side of dial plate, arc groove is set, arc groove edge arranges the over cap that covers water meter dial plate, monitoring pointer is set in dial plate, the length of monitoring pointer is slightly less than the diameter of dial plate, its rotation axis is arranged on the center of circle of dial plate, its root arranges metallic conductor, on signals collecting conveyer, pick-up transducers is set, sensor utilizes two telefaults and two two LC free harmonic vibration damped vibraions that capacitor forms, and timing gives oscillator pulses pumping signal, when pointer rotates, conductor is near inductance, damped oscillation amplitude decays rapidly.
On dial plate circumference, scale is set.
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.
The processing unit of judgement uninterrupted is set in signals collecting conveyer, and processing unit connects pick-up transducers and detects damped oscillation attenuation in pick-up transducers and measure the number of turns that pointer rotates, and described processing unit is single-chip microcomputer.
In described signals collecting conveyer, communication unit is set, communication unit is M_BUS or RS485 telecommunication circuit, and communication unit 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 supply unit is single-chip microcomputer, communication unit and sensor power supply.
Beneficial effect: the utility model compared with prior art, it departs from the setting of water meter body by signals collecting conveyer, easy to maintenance, and can to circuit component, change according to actual conditions, time and manpower is saved for it, avoided the waste of material, and the utility model is measured current volume and realized by measuring the damped oscillation time, and what it was interfered may reduce greatly, and use large pointer as monitoring pointer, its rotating speed is slower, and monitoring accurately.

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, a monitoring pointer 4 is set in the dial plate of water meter body 1, the length of monitoring pointer 4 is slightly less than the diameter of dial plate, its rotation axis is arranged on the center of circle of dial plate, its root arranges metallic conductor, along with monitoring pointer 4 rotates, metallic conductor also rotates thereupon, when the object that larger monitoring pointer 4 is set is that the discharge in water meter is larger, the rotating speed of pointer can be controlled, so just there will not be monitoring to leak the phenomenon of circle, guaranteed the monitoring accuracy of water meter.Top at water meter body 1, be provided with signals collecting conveyer 2, specifically, signals collecting conveyer 2 is arranged on a side on water meter top, its some cover dial plate top and according to the shape of dial plate, one arc-shaped recess be set, at the arc-shaped recess place on movement locus top that is provided with the pointer of magnet, be provided with pick-up transducers 3, sensor is the LC free harmonic vibration damped vibraion that utilizes telefault and capacitor to form, be divided into the first oscillator and the second oscillator, oscillator regularly gives pulse excitation signal, when pointer rotates, metallic conductor is near inductance, metallic conductor inside has produced induction current, consumed portion of energy, damped oscillation amplitude sharp-decay.The monitoring pointer 4 that metallic conductor is set described in the utility model is arranged according to actual conditions, is traditionally arranged to be x0.01 times of pointer.
Sensor gathers the minimum amplitude amplitude input signal of damped vibraion in conveyer and analyzes, in signals collecting conveyer, single-chip microcomputer is set, single-chip microcomputer connecting sensor, in single-chip microcomputer, set a threshold value and itself and the amplitude receiving are compared, when amplitude minimum value is during much smaller than setting threshold, provide a decision signal, specifically, when the minimum amplitude of the first oscillator is during much smaller than setting threshold, single-chip microcomputer provides signal A temporary; The minimum amplitude of the second oscillator is during much smaller than setting threshold, and single-chip microcomputer provides signal B, and while there is in succession A and B signal in single-chip microcomputer, single-chip microcomputer judges that pointer rotates a circle.If only have continuation a-signal or continuation B signal, temporary signal is deleted to the measurement error that while having avoided like this metal finger to stop, continuous metering causes under oscillator.Thereby the number of times simultaneously occurring by measurement A, B signal converses the flow of water in water meter.
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, guarantee that memory device normally moves, can not store and overflow.
In signals collecting conveyer, be also provided with communication unit, when user's handheld device, send after request, single-chip microcomputer extracts data, after encoding, by communication unit, sends; Or directly by long-range GPRS access, obtain data.In the utility model, 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 utility model, described fixed form is preferably used trip to connect or bolt connecting mode, like this when 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.
