Abstract
The invention relates to a water meter character wheel, in particular to an electronic remote-reading water meter character wheel and belongs to the technical field of water flow metering equipment. The electronic remote-reading water meter character wheel comprises a wheel body (30), wherein twenty transmission teeth (31) are distributed on one side of the wheel body (30) in a ringlike mode; three fan-shaped window (32) of different sizes are arranged on the wheel body (30); the three fan-shaped windows (32) are coaxial with a wheel hole (33) and positioned on the same circumference; the wheel body (30) is made of a light-proof material. The three fan-shaped windows (32) of different sizes are arranged on the wheel body (30), so that the electronic remote-reading water meter character wheel has the advantage that the reading accuracy is high.
Description
Technical field
The present invention relates to a kind of water meter character wheel, especially relate to a kind of electronic remote transmission water meter character wheel, belong to discharge metering equipment technical field.
Background technology
A lot of in recent years remote transmitting water meter manufacturers have developed electronic remote transmission water meter of new generation; It comprises essentic-water-meter, sampling section and SCM system; Be characterized in through being installed in character wheel middle four groups or three groups of photoelectric tubes; Cooperate the fan-shaped window on the character wheel, differentiate the character wheel position, thereby reached the purpose of metering with singlechip technology.The character wheel that generally uses at present offers a fan-shaped window on its wheel body, photoelectric tube adopts area array light source; Cause fan-shaped window to block the position difference through the character wheel rotation, make different position on the corresponding character wheel of photoelectric tube, thereby discern different character wheel readings; And then carry out active data output, but have only a fan-shaped window owing on its wheel body, and the photoelectric tube employing is area array light source; Deviation appears in the differentiation of character wheel present position easily, influences the accuracy of reading.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, provide a kind of accuracy of reading property higher electronic remote transmission water meter character wheel.
The objective of the invention is to realize like this: a kind of electronic remote transmission water meter character wheel; It comprises wheel body; Said wheel body one side is provided with driving cog, and driving cog quantity is 20 and distributes in the form of a ring, is characterized in: also be provided with three fan-shaped windows that vary in size on the wheel body; Said three fan-shaped windows and wheel hole concentric, and three fan-shaped windows are positioned on the same circumference.
Said wheel body adopts light-proof material to process.
Compared with prior art, the invention has the beneficial effects as follows:
A kind of electronic remote transmission water meter character wheel of the present invention; Its wheel body is provided with three fan-shaped windows that vary in size; Five groups of photoelectric sensors that cooperate its both sides to be provided with again; Angle and the residing position that can differentiate current character wheel accurately and rotated through SCM system, and then can read the reading of present character wheel exactly.
Description of drawings
Fig. 1 is the structural representation of a kind of electronic remote transmission water meter character wheel of the present invention.
Fig. 2 is that the high-low level of photoelectric sensor changes sequential chart.
Wherein:
Wheel body 30, driving cog 31, fan-shaped window 32, wheel hole 33.
Embodiment
Referring to Fig. 1, the present invention relates to a kind of electronic remote transmission water meter character wheel, it comprises wheel body 30; Said wheel body 30 adopts light-proof material to process, and wheel body 30 centers are provided with wheel hole 33, and wheel body 30 1 sides are provided with driving cog 31; Driving cog 31 quantity are 20 and distribute in the form of a ring; Also be provided with three fan-shaped windows 32 that vary in size on the wheel body 30, said three fan-shaped windows 32 and wheel hole 33 concentrics, and three fan-shaped windows 32 are positioned on the same circumference.
During use, wheel body 30 symmetria bilateralis are equipped with five groups of photoelectric sensors of being made up of photoelectric tube and photoelectric receiving tube of ABCDE, and photoelectric tube adopts the infrared ray pointolite; In the process of character wheel rotation; The relative position of three fan-shaped windows 32 and five groups of photoelectric sensors can change, if the light of photoelectric tube is blocked by wheel body 30, this moment, photoelectric receiving tube was in high level; If the light of photoelectric tube is received by photoelectric receiving tube through fan-shaped window 32; This moment, photoelectric receiving tube was in low level, because three fan-shaped windows 32 vary in size and are in the position of regulation, can make the every rotation of character wheel a kind of different high-low level state all will occur for 12 °; The a series of different conditions that rotate a circle and occurred according to character wheel; The high-low level that can obtain photoelectric sensor changes sequential chart (as shown in Figure 2), can determine angle and the present residing position of character wheel that character wheel rotated under a certain time sequence status through SCM system, and then carries out active data output.
