Specific implementation mode
Below with reference to the embodiments and with reference to the accompanying drawing doing specific description to the technical solution of the utility model.
Embodiment 1：A kind of gas meter, flow meter based on Hall sensor counter, gas meter, flow meter 7,1# Hall sensors 9 and 2#
Hall sensor 10 is commodity prototype part, and 1# is installed on the counter 15 of gas meter, flow meter 7, and Lovell is sensed suddenly by Lovell sensors 9 and 2# suddenly
Device 10, counter 15 include counter assembly 1, tally assembly 2 and fixed frame 3.
The counter assembly 1 includes skeleton 4, character wheel 5, magnetic patch 6.Skeleton 4 is fixed on gas meter, flow meter 7, and skeleton 4 is equipped with word
Wheel 5, general character wheel 5 are seven, and character wheel 5 is that gas meter, flow meter 7 commonly uses round character wheel 5.Magnetic patch 6 is chosen cylindrical magnetic patch 6 and is installed on
On skeleton 4 on the character wheel 5 of least significant end, magnetic patch 6 is flush-mounted in the side of character wheel 5, the general side for being loaded on 5 number 2 of character wheel, magnetic patch 6
Without dividing the poles N and S extreme directions when installation, 6 axis of cylindrical magnetic patch is perpendicular to 5 axis of character wheel, and when character wheel 5 rotates, magnetic patch 6 encloses
It is rotated around 5 axis of character wheel, magnetic patch 6 is by the 1# Hall sensors 9 with tally 8（Honeywell, SL353）The vertical position in face
When setting, that is, magnetic patch 6 and 1# Hall sensors 9 apart from it is nearest when, magnetic that magnetic patch 6 is generated in 9 sensitive face of 1# Hall sensors
Field is more than the trigger value of 1# Hall sensors 9, the 1# Hall sensors 9 of 6 flip-flop number plate assembly 2 of magnetic patch；When character wheel 5 continues to turn
Dynamic, magnetic patch 6 is triggered far from 1# Hall sensors 9, the stopping of 1# Hall sensors 9；This process makes 1# Hall sensors 9 export one
A signal, signal are received by line 11 by circuit unit 12, have display unit 13 on circuit unit 12, finally by output signal
It is exported in the form of display unit 13, reaches the final display effect of the counting of gas meter, flow meter 7.5 turns of the count signal of output and character wheel
The number of turns is consistent, and the numerical value that display unit 13 is shown is exactly the variable that gas meter, flow meter 7 actually uses combustion gas.
Tally assembly 2 is installed on two cylinders of fixed frame 3, first wears line 11 from the circular hole of fixed frame 3
It crosses, two cylinders for then leaking out residue plate.Tally assembly 2 is fixed on counter assembly 1, tally assembly 2
After being installed on counter assembly 1, the 1# Hall sensors 9 of counting are placed exactly in the underface of character wheel 5.9 body of 1# Hall sensors
Product is small and exquisite, helps to reduce PCB space size, number of components and overall application cost, installs simple and convenient and low-power consumption.
The tally assembly 2 includes tally 8, Hall sensor 1#9, Hall sensor 2#10 and line 11.It counts
Plate 8 is single sided copper clad PCB, PCB size according to fixed frame matched design, 9 He of design installation 1# Hall sensors on tally 8
2# Hall sensors 10, the right side welding 1# Hall sensors 9 of tally 8, play the role of counting, when character wheel 5 rotates one week
When, Hall sensor 1#9 can trigger and export a signal, and 2# Hall sensors 10 are welded on the left side, when there is extraneous magnet close
When near 7 magnetic patch 6 of gas meter, flow meter, extraneous magnet can trigger the 2# Hall sensors 10,10 output signal of 2# Hall sensors, letter
It number is received by circuit unit 12, circuit unit 12 can carry out closing 7 motor valve valve 14 of gas meter, flow meter after receiving the signal, make combustion gas
Table 7 is stopped using, and on display unit 13 and magnetic disturbance signal is shown, to achieve the effect that prevent surreptitiously gas；1# Hall sensors 9
With the digital Hall effect device of 2# Hall sensors 10, the magnetic field generated by permanent magnet or electromagnet controls, so magnet
North magnetic pole or south magnetic pole can be responded, that is, be not necessarily to distinguish magnetic pole, make the simpler convenience of 7 integral installation of gas meter, flow meter；Line
11 use four core ribbon plug-type harness, 11 one end of line to be welded in tally 8, and one end is connected to circuit unit 12.
The gas meter, flow meter of counter with Hall sensor can be widely applied to IC card, wireless remote transmission, Internet of Things, N2#10-
The products such as IOT gas meter, flow meters.
Embodiment 2：Two magnetic patch 6 can be filled on character wheel 5, two 6 axis of magnetic patch are each perpendicular to 5 axis of character wheel and two magnetic
Block 6 is distributed in 180 degree.When character wheel 5 rotates, magnetic patch 6 is rotated around 5 axis of character wheel, and magnetic patch 6 is by the 1# with tally 8
When 9 face upright position of Hall sensor, that is, magnetic patch 6 with count 1# Hall sensors 9 apart from it is nearest when, magnetic patch 6 is in 1#
The magnetic field that 9 sensitive face of Hall sensor generates is more than the trigger value of 1# Hall sensors 9, the 1# of 6 flip-flop number plate assembly 2 of magnetic patch
Hall sensor 9；When character wheel 5 is rotated further, magnetic patch 6 is triggered far from 1# Hall sensors 9, the stopping of 1# Hall sensors 9；This
Process makes 1# Hall sensors 9 export a signal, and signal is received by line 11 by circuit unit 12,
There is display unit 13 on circuit unit 12, finally exports output signal in the form of display unit 13.Character wheel 5 rotates
One circle, two magnetic patch 6 are primary with the Hall sensor 1#9 effects on tally 8 respectively, and one circle of the rotation of such character wheel 5 will output
Two signals, two signals carry out one counting of processing output by circuit unit 12, are finally shown in display unit 13.
Other increase the reliability and stability of counting with 1. two 6 forms of magnetic patch of embodiment, improve the metering essence of gas meter, flow meter 7
Degree.
