Description
[technical field]
The present invention relates to flow metering device technical field, in particular to the sender of a kind of forward and reverse Hall metering of water meter band
Circle.
[background technique]
The signal acquisition of intellectual water meter is always the numerous producers of this industry technical problem to be solved, cheap, batch
It measures reliable and stable, there is very long service life, be the target of our this industry indexing.
The sensor (sender circle) of water meter, tongue tube pulse sender circle: tongue tube is also a kind of pulse collection mode, because
Its cost is cheap, and fault point is seldom, is attracted number and is greater than 1,000,000 times or more, has more applications on water meter, but because be after all
The attracting mode of machinery examination, with the presence of jitter phenomenon, while having should be larger because of volume, and structure is mounted on the machine core of water meter
Face is difficult to accomplish walking direction, and the physical space for installing three tongue tubes is inadequate, therefore uses very on remote transmitting water meter at present
It is few.Go alone reed pipe sensor, i.e., the sensing system of the extraction signal formed with single magnet and a tongue tube, mainly by magnetic
Body makes tongue tube be attracted and disconnect to issue useful signal: as schemed, when magnet is close to tongue tube reed, magnetic force, which arrives greatly, can overcome spring
When the elastic force of piece, reed is just attracted short circuit；When magnet is far from reed, reed is just separated when attraction is less than elastic force, i.e. an arteries and veins
Punching issues.This mode occurs relatively early, and structure is simple, power saving, but when the magnetic line of force makes the reed of dry reed tube be in critical state (i.e.
Attraction is equal with the elastic force of reed) when, slightly external interference (such as water hammer), reed will be attracted and break with external force
It opens, issues bursts of error.Though situation take a favorable turn after filtering, but still cannot avoid malfunction signal input completely.For this purpose, I
Propose the sender circle of the forward and reverse Hall metering of water meter band a kind of.
[summary of the invention]
The main purpose of the present invention is to provide a kind of sender circles of the forward and reverse Hall metering of water meter band, can effectively solve
The problems in background technique.
To achieve the above object, the technical scheme adopted by the invention is as follows:
A kind of sender circle of the forward and reverse Hall metering of water meter band, including shell, the shell are equipped with pipeline, in the shell
Portion is equipped with shaft, and the shaft is equipped with impeller, is equipped with magnet ring at the top of the shaft, the magnet ring is equipped with magnet, institute
It states case top and Hall element is installed positioned at the side of magnet ring.
Further, the Hall element includes hall sensing chip A and hall sensing chip B.
Further, the Hall element uses unipolarity Hall.
Further, the Hall element is also electrically connected with control single chip computer.
Compared with prior art, the invention has the following beneficial effects:
1, the conducting and disconnection of Hall element are determined using polarity, magnet Gauss value can be done so greatly, guarantee to produce
The reliability of product.
2, using a magnet, structure is simple, and circumferentially movement is to change the direction of the magnetic line of force, to make Hall element
On-off.
3, it is simultaneously turned on using two Halls, can identify the positive and negative rotation of water meter, and then solve the metering accuracy of water meter.

[specific embodiment]
To be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, below with reference to
Specific embodiment, the present invention is further explained.
As shown in Figure 1-3, a kind of sender circle of the forward and reverse Hall metering of water meter band, including shell 1, the shell 1 are equipped with
Pipeline 4 is equipped with shaft 2 inside the shell 1, and the shaft 2 is equipped with impeller 3, is equipped with magnet ring 6 at the top of the shaft 2,
The magnet ring 6 is equipped with magnet 7,1 top of the shell and side for being located at magnet ring 6 is equipped with Hall element 5.
A kind of sender circle of the forward and reverse Hall metering of water meter band of the present invention, the present invention use unipolarity Hall element 5, according to
For magnet 7 in circular motion, when close, magnetic line of force direction is consistent with Hall original part 5, when separate, magnetic line of force direction and Hall
The opposite polarity principle of element 5 guarantees magnet 7 when moving in a circle, and Hall element 5 can be connected and disconnect well, simultaneously
Also it can guarantee that four states be connected, disconnect, simultaneously turning on, simultaneously switching off, therefore single-chip microcontroller occur in two hall sensing chips
The water (flow) direction that can judge water meter is to rotate forward or invert, when magnet 7 is close to Hall original part 5, close to hall sensing chip
When A51, hall sensing chip A51 is first connected, and then hall sensing chip B52 is connected, and then hall sensing chip A51 is disconnected,
Then hall sensing chip B52 is disconnected, and is thus existed and is simultaneously switched off, simultaneously turns on, single to be only connected, single only to disconnect four shapes
State, it is contrary needed for the direction of the magnetic line of force and Hall original part 5, it is easy to disconnected when magnet 7 is gone to far from Hall original part 5
Open, as long as selection Gauss in this way is worth very big magnet, guarantee the stability of pulse signal, rather than by magnet diameter about
Variation distance is moved on 10 millimeters of circular motion, generates changing magnetic field size to determine the conducting and actuation of Hall.
Wherein, the Hall element 5 includes hall sensing chip A51 and hall sensing chip B52.
Wherein, the Hall element 5 uses unipolarity Hall.
Wherein, the Hall element 5 is also electrically connected with control single chip computer.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent thereof.
