Water meter counting apparatus described in the utility model, when pointer rotates, the first magneto-dependent sensor and the second magneto-dependent sensor are exported respectively low and high level signal, and pointer is during through the first magneto-dependent sensor induction region, and compute chip receives low level; Pointer is during through the first magneto-dependent sensor and the overlapping induction region of the second magneto-dependent sensor, and compute chip receives overlapped signal; Pointer is during through the second magneto-dependent sensor induction region, and compute chip receives high level.In one-period, if there is successively low level signal-overlapped signal-high level signal, can judge that pointer turns clockwise, compute chip is carried out add one operation; If there is successively high level-overlapped signal-low level signal, can judge that pointer is rotated counterclockwise, compute chip subtracts a computing.Solve in the situation of existing water meter employing single-sensor, no matter current are forward flow or reverse flow, the shortcoming that all can make water meter counter reading increase; In addition, only have a larger angle of pointer rotation just can make two sensors produce pulse signal simultaneously, prevent the counting error that in single-sensor situation in the past, pointer shake causes.
The utility model is also constructed a kind of intellectual water meter, comprise watermeter shell, the water meter movement being driven by current in watermeter shell, and the magnetic pointer being rotated by movement drive that is positioned at watermeter shell upside, outer rim in the rotation of magnetic pointer is provided with the first magneto-dependent sensor and the second magneto-dependent sensor, the first magneto-dependent sensor is different with the level amplitude of the second magneto-dependent sensor output pulse signal, and the induction region of the first magneto-dependent sensor and the second magneto-dependent sensor partly overlaps, the first magneto-dependent sensor and the second magneto-dependent sensor are all connected to compute chip input end, send detection signal to compute chip, the output terminal of compute chip connects display screen again, operation result is transported to display screen to be shown.
Intellectual water meter described in the utility model, thereby the plus-minus that the signal that compute chip passes over according to two magneto-dependent sensors judgement water (flow) direction is correlated with calculates, further improved the counting precision of water meter, the counting error that can effectively avoid pointer shake to cause.

Embodiment
A kind of water meter counting apparatus as depicted in figs. 1 and 2, rotating counting pointer is magnetic pointer, outer rim in the rotation of magnetic pointer is provided with the first magneto-dependent sensor 1 and the second magneto-dependent sensor 2, the first magneto-dependent sensor 1 is different with the level amplitude of the second magneto-dependent sensor 2 output pulse signals, and the induction region of the first magneto-dependent sensor 1 and the second magneto-dependent sensor 2 partly overlaps, the first magneto-dependent sensor 1 and the second magneto-dependent sensor 2 are all connected to compute chip input end, send detection signal to compute chip, the output terminal of compute chip connects display screen again, operation result is transported to display screen to be shown.When magnetic pointer rotates, the first magneto-dependent sensor 1 and the second magneto-dependent sensor 2 are exported respectively low high level signal, and pointer is during through the first magneto-dependent sensor 1 induction region, and compute chip receives low level; Magnetic pointer is during through the first magneto-dependent sensor 1 and the overlapping induction region of the second magneto-dependent sensor 2, and compute chip receives overlapped signal; Magnetic pointer is during through the second magneto-dependent sensor 2 induction region, and compute chip receives high level.In one-period, if there is successively low level signal-overlapped signal-high level signal, can judge that magnetic pointer turns clockwise, compute chip is carried out add one operation; If there is successively high level-overlapped signal-low level signal, can judge that magnetic pointer is rotated counterclockwise, compute chip subtracts a computing.Solve in the situation of existing water meter employing single-sensor, no matter current are forward flow or reverse flow, the shortcoming that all can make water meter counter reading increase; In addition, a larger angle of the pointer that is only magnetic rotation just can make two magneto-dependent sensors produce pulse signal simultaneously, prevents the counting error that in single-sensor situation in the past, pointer shake causes.
As Fig. 2, a kind of intellectual water meter shown in 3, comprise watermeter shell, the water meter movement being driven by current in watermeter shell, and the magnetic pointer being rotated by movement drive that is positioned at watermeter shell upside, outer rim in the rotation of magnetic pointer is provided with the first magneto-dependent sensor 1 and the second magneto-dependent sensor 2, the first magneto-dependent sensor 1 is different with the level amplitude of the second magneto-dependent sensor 2 output pulse signals, and the induction region of the first magneto-dependent sensor 1 and the second magneto-dependent sensor 2 partly overlaps, the first magneto-dependent sensor 1 and the second magneto-dependent sensor 2 are all connected to compute chip input end, send detection signal to compute chip, the output terminal of compute chip connects display screen again, operation result is transported to display screen to be shown.
Wherein, magneto-dependent sensor be arranged on magnetic pointer rotation outer rim above or below.Two magneto-dependent sensors are the first magneto-dependent sensor 1 and the second magneto-dependent sensor 2, and the angle between the first magneto-dependent sensor 1 and the second magneto-dependent sensor 2 and magnetic pointer shaft is 45 °, and the signal resolution of generation is best.Movement comprises impeller 7 and transmission gear 6, when current process water meter, and drive impeller 7 rotations, impeller 7 is by 6 rotations of impeller shaft band nutating gear, and magnetic pointer 5 always keeps same speed to rotate with transmission gear 6 by gear shaft.When magnetic pointer rotates, the first magneto-dependent sensor 1 and the second magneto-dependent sensor 2 are exported respectively low and high level signal, and magnetic pointer is during through the first magneto-dependent sensor 1 induction region, and compute chip receives low level; Pointer is during through the first magneto-dependent sensor 1 and the overlapping induction region of the second magneto-dependent sensor 2, and compute chip receives overlapped signal; Magnetic pointer is during through the second magneto-dependent sensor 2 induction region, and compute chip receives high level.In one-period, if there is successively low level signal-overlapped signal-high level signal, can judge that pointer turns clockwise, compute chip is carried out add one operation; If there is successively high level-overlapped signal-low level signal, can judge that pointer is rotated counterclockwise, compute chip subtracts a computing., for example, there is low level or high level in other situations, can think pointer shake intermittently, and compute chip is not carried out computing.
Magnetic pointer body can be nonmagnetic substance and makes, and only one end arranges magnet steel, as Fig. 2.The use of its material that can deperm, reduces cost of manufacture.Also can be provided with magnet steel at the two ends of pointer body, as Fig. 3, by two ends, magnet steel is set, magnetic pointer only need turn over half-turn just can complete a count cycle, be equivalent to precision and be doubled, even when discharge is fewer, also can realize accurately counting, improve precision and the sensitivity of water meter, expanded the scope of application of water meter.
