Specific embodiment
The present invention is described in further detail with reference to specification：
The present invention relates to a kind of new remote transmitting water meter, including water meter body 1, one is set in the dial plate of water meter body 1
Root monitors pointer 4, and the length for monitoring pointer 4 is slightly less than the diameter of dial plate, and its rotary shaft is arranged on the center of circle of dial plate, and its root sets
Metallic conductor is put, as monitoring pointer 4 is rotated, metallic conductor also concomitant rotation, the purpose for setting larger monitoring pointer 4 is
When the water-carrying capacity in water meter is larger, the rotating speed of pointer can be controlled, and so just be not in the phenomenon of monitoring leakage circle, be protected
The monitoring accuracy of water meter is demonstrate,proved.On the top of water meter body 1, signal acquisition conveyer 2 is provided with, specifically, signal is adopted
Collection conveyer 2 is arranged on the side on water meter top, its some be covered in dial plate top and set according to the shape of dial plate
One arc-shaped recess, collection sensor 3, sensing are provided with being provided with the arc-shaped recess on the movement locus top of the pointer of magnet
Device be using inductance coil and capacitor bank into LC free harmonic vibration damped vibraions, be divided into the first oscillator and vibrated with second
Device, oscillator timing gives pulse excitation signal, and when indicators turn, metallic conductor is produced near inductance, metallic conductor inside
Induced-current, consumes portion of energy, damped oscillation amplitude sharp-decay.The heretofore described monitoring that metallic conductor is set
Pointer 4 is set according to actual conditions, is traditionally arranged to be x0.01 times of pointer.
Sensor will be analyzed in the minimum amplitude amplitude input signal collection conveyer of damped vibraion, in signal
Single-chip microcomputer is set in collection conveyer, single-chip microcomputer connection sensor one threshold value of setting and by it and is received in single-chip microcomputer
Amplitude is compared, and when amplitude minimums are much smaller than given threshold, then a judgement signal is provided, specifically, when first
When the minimum amplitude of oscillator is much smaller than given threshold, single-chip microcomputer provides signal A and keeps in；The minimum amplitude of the second oscillator is remote
During less than given threshold, single-chip microcomputer provides signal B, and when occurring A in single-chip microcomputer in succession with B signal, single-chip microcomputer judges that pointer turns
A dynamic circle.If only continuation a-signal or continuation B signal, temporary signal is deleted, exist this avoid metal finger
Measurement error caused by continuous metering when stopping under oscillator.By measuring the number of times of A, B signal appearance simultaneously so as to converse
The flow of water meter reclaimed water.
Recorded in the memory cell that the flow of the current for conversing is set in signal acquisition conveyer, and stamped
Corresponding timestamp, at regular intervals, the new data for adding just are covered oldest data, it is ensured that storage device is normal
Operation, will not store spilling.
Communication unit is also provided with signal acquisition conveyer, after the handheld device of user sends request, monolithic
Machine extracts data, is sent by communication unit after being encoded；Or directly by long-range GPRS access obtain data.This
In invention, communication unit is M_BUS or RS485 telecommunication circuits.
Heretofore described signal acquisition conveyer is detachably mounted to water meter body top, and the fixed form is excellent
Choosing is connected or bolt connecting mode using trip, so when signal acquisition conveyer breaks down, can very easily be given
To change, without water meter is pulled down completely, firstly reduce manually, while also saving cost.
