Description
Technical field
The invention belongs to mechanical water meter reading field, more particularly to a kind of new water meter mechanical character wheel direct-reading to implement system.
Background technology
Water meter, it is the instrument for measuring water-carrying capacity, is the integrated flow measurement of water mostly, is generally divided into volumetric water meter and speed
The class of degree formula water meter two, originating from Britain, the development of water meter has the history of nearly 200 years, when selecting water meter specification, should first estimate
The size and range of flow of used flow under normal circumstances, conventional flow is then selected closest to the water of that specification of the value
Table is as preferred.Traditional water meter is inconvenient there is reading, and meter reading is difficult, and water meter measurement is forbidden, also has and be in arrears with water rate
Situation is present.
In summary, the problem of prior art is present be：Traditional water meter is inconvenient there is reading, and meter reading is difficult, water
Meter amount is forbidden, and also has the situation for being in arrears with water rate and exists.
The content of the invention
The problem of existing for prior art, the invention provides a kind of new water meter mechanical character wheel direct-reading to implement system.
The intention of the present invention is mainly that the photoelectricity character code identification side examination that the original transmitting of monochrome 5/5 receives is improved into three colors 1 to launch/2
The photoelectricity identification method of reception, three-dimensional identification is improved to by one-dimensional identification, greatly reduces the component number needed for identification.
The present invention is achieved in that system, the new water meter machinery are implemented in a kind of new water meter mechanical character wheel direct-reading
Character wheel direct-reading implements system and is provided with character wheel, all-colour LED lamp bead, photoelectric receiving tube, light shield, optical filtering.It is special on the character wheel
Determine to drill between character code, the optical filtering for setting color is loaded in hole, the all-colour LED lamp bead is arranged on character wheel side PCB
On, corresponding with the central axis in two holes on character wheel, the photoelectric receiving tube is arranged on character wheel opposite side, with all-colour LED lamp bead
Close to two holes it is corresponding, the light shield blocks the light beyond corresponding two holes of photoelectric receiving tube.
Further, the bore position is set as 1/2,2/3,3/4,4/5,5/6,6/7,8/9.
Further, the color of the optical filtering paper and the position correspondence of hole are：1/2nd, 4/5 red is set；2/3rd, 6/7 set
Green；3/4th, 5/6,8/9 blueness is set.
Advantages of the present invention and good effect are：The new water meter mechanical character wheel direct-reading implements system and passes through full-color LED lamp
Red, green, blue three coloured light is sent successively, receives two binary codes from two photoelectric tubes every time, receives six binary systems three times
Code, shares 32 kinds of states, misaligned 10 groups is selected from the code character being likely to occur, you can realizes the reality that identification character wheel rotates
Position.The present invention is simple in construction, ingenious in design, saves the energy, and water-meter reading registration is very convenient.
5 debit's cases of existing monochromatic 5 hair realize plane identification (the character wheel garden plan-position identification of low-cost mechanical position
The identification of multi-emitting more receiving plane point positions.The present invention realizes single-shot and penetrates more receiving plane point position identifications.If use this
The method of invention is generalized to multi-emitting (more colors) and the motor point identification for receiving, then three dimensions can be achieved more.This is in machine
People identifies there is great meaning to peripolesis body point position.What if the very high reception pipe of cost can identify is what
Color of light, can of the present invention is only with a reception pipe, that is to say, that a hair one, which is received, is assured that something moves to plane
On that position.Same method can identify another plane vertical with this plane again, in theory for can know
Other object point is in the position in space.So it is very valuable to be used for machine for inexpensive recognition methods.And original multi-emitting is more
Reception is only used for plan-position identification, and the present invention has profound meaning.

Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to embodiments, to the present invention
It is further elaborated.It should be appreciated that specific embodiment described herein is not used to limit only to explain the present invention
The fixed present invention.
The structure of the present invention is explained in detail below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, system is implemented in the new type water provided in an embodiment of the present invention/gas meter, flow meter mechanical character wheel direct-reading
It is provided with character wheel 1, all-colour LED lamp bead 2, photoelectric receiving tube 3, light shield 4, optical filtering 5.On the character wheel 1 between specific character code
Drilled on correspondence position, the optical filtering 5 for setting color is loaded in hole, the all-colour LED lamp bead 2 is arranged on character wheel 1 one
Corresponding with the central axis in two holes on character wheel 1 on the PCB of side, the photoelectric receiving tube 3 is arranged on character wheel opposite side, and full-color
LED lamp bead 2 close to two holes it is corresponding, the light shield 4 blocks the light beyond corresponding two holes of photoelectric receiving tube 3.
Bore position provided in an embodiment of the present invention is set as between numeral 1/2,2/3,3/4,4/5,5/6,6/7,8/9.
The color of optical filtering 5 provided in an embodiment of the present invention and the position correspondence of hole are：Set between numeral 1/2,4/5
It is red；Green is set between numeral 2/3,6/7；Blueness is set between numeral 3/4,5/6,8/9.
The setting photoelectric receiving tube of the present invention exports high level 1 in no light, exports low level 0 when having illumination, passes through
With single-chip microcomputer control all-colour LED lamp bead put azarin, green, blue light pearl successively, if now have on two wide range photoelectric receiving tubes with it is right
Answer the LED lamp bead of filter color to be lit, then can receive optical signal and export low level 0, otherwise can not receive output high level 1.
In form shown in Fig. 3, the first behavior character wheel position；In second row, the black non-punch position of representative, red, green, blue point
Load respective color optical filtering after Dai Biao not punching；The third line fourth line is respectively the optical signal that two photoelectric receiving tubes receive
Coding (it is 0 to have light)；Fifth line is that the above-mentioned coding received after the green blue light pearl of azarin of sequentially being put three times in same position is formed
Identification code；Read identification code, you can table look-up and judge character wheel position, because the identification code of each position is inconsistent.In addition, only
Have when needing reading, startup single-chip microcomputer controls full-color RGB lamp beads to light successively and is once achieved with character wheel position, thus power consumption
It is atomic.
There is unglazed (1) signal of light (0) to form triad code according to what is received three times, table look-up and would know that character wheel position
Put.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement made within refreshing and principle etc., should be included in the scope of the protection.
