Description
Technical field
The utility model relates to a kind of water meter counter.
Background technology
In direct-reading water meter, the mechanical character wheel reading is converted to electronical reading at present and mainly contains following several method:
Collect pulse singaling
This mode adopts the on-off action of magnet for magnetosensitive devices such as reed pipe, Hall elements, the cumulative measurement pulse signal.Owing to be subject to external magnetic field influence, be easy to generate cumulative errors, and the power supply when taking of this type of sensor, there is very big drawback.
The shooting direct-reading
This scheme volume of transmitted data causes the cost height greatly, and the user is difficult to accept, and it is big to promote difficulty.
Infrared direct-reading scheme
At present more advanced and be each producer widely used be that the character wheel end face is slotted, as the disclosed direct-reading water meter of the Chinese patent literature CN2919201Y coaxial coding counter of photoelectricity, by shell, 4 coaxial coding print wheels, four or eight gear wheels, circuit board and photoelectric sensor constitute, the both sides of each character wheel all are provided with the coaxial disc that photoelectric sensor is installed, the disk upper end is connected as a single entity with circuit board. and wherein the end face of each character wheel is divided into 30 equal angles covering of the fans by 30 group codings, be printed with 0～9 numeral on the character wheel cylinder, each numeral accounts for 3 equal angles covering of the fans, and every group coding is made of 5 bits.Be distributed with 3 sections circular holes on each character wheel, on a concentric circles, arc angle is respectively 24 °, 96 ° and 60 °.5 photoelectric sensors are installed on the disk of character wheel both sides, 5 photoelectric sensors evenly distribute at a concentric circles, this concentric circles is identical with the residing concentric circles radius of 3 sections circular holes on the character wheel, its can reach reading easily, discern effect accurately, but the weak point of this scheme is that three groove requirement on machining accuracy of coding print wheel are higher, otherwise the carry blind area will occur.And because five photoelectric sensors are evenly distributed on the same circumference, make that electro-optical package must be in the form of annular discs, so it is applicable to dry-type meter, is difficult on liquid-sealing water meter, use.
The utility model content
Technical problem to be solved in the utility model is to overcome the above-mentioned deficiency of prior art and a kind of direct-reading water meter photoelectricity coding counter is provided, make its make simple, counting is more accurate.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
Direct-reading water meter photoelectricity coding counter, comprise several coding print wheel of counter, four or eight gear wheels, optical-electric module, it is characterized in that: the end face of each coding print wheel is left an arc groove coaxial with character wheel, the external arc institute of groove is 198 ° to central angle, interior circular arc right central angle be 162 °, the two-end-point of inside and outside circular arc connects with a line segment or several line segments, arc groove system is the symmetric figure of axis of symmetry with the radius that connects arcuate midway point, evenly prints ten numerals of 0-9 on the coding print wheel face of cylinder; Optical-electric module is made up of some electro-optical packages and the circuit board that is welded with electron device, the one side of every electro-optical package has 5 light-emitting components, 5 light activated elements are arranged on the another side correspondence position, 5 light-emitting components and 5 light activated elements all by at interval 36 ° be evenly arranged into fan-shapedly, this fan-shaped catching up with is stated the arc groove correspondence; Some electro-optical packages and coding print wheel be assembling alternately, constitutes the photoelectric coding of long number under drives.
Compared with prior art, advantage of the present utility model is:
1. an arc groove is only opened on the coding print wheel face of cylinder, and mould is opened system and conveniently is easy to processing, helps producing in batches.
2. the special grooved of coding print wheel makes the right state of photoelectricity be extended for four kinds of states from the two states (switching) of other scheme, is convenient to judge the carry attitude, can eliminate " reading blind area " that other scheme exists at all.
3. arranging of photoelectric sensor is semicircle, so electro-optical package is easy for installation, both has been applicable to the counter of dry-type meter, also is applicable to the counter of liquid-sealing water meter, and range of application is big, can adapt to the needs in market fully.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, the arc surface of each coding print wheel 1 is established an arc groove 11 coaxial with character wheel, the external arc 12 pairing central angles of groove are 198 °, interior circular arc 10 pairing central angles are 162 °, the two-end-point of external arc 12, interior circular arc 10 connects with three line segments 13,14,15, the arc groove 11 that constitutes is an axis of symmetry with the diameter 16 of coding print wheel 1, evenly prints ten numerals of 0-9 on coding print wheel 1 face of cylinder.
The 5 pairs of optical sensors (infrarede emitting diode 21 and phototriode 22) that are positioned at coding print wheel 1 both sides are installed on the electro-optical package 2, are even fan-shaped distribution respectively, and per two adjacent pipes institute is 36 degree to central angle.Fan-shaped coaxial with arc groove 11.At opposite side, the position is corresponding one by one at a side, 5 photosensitive tubes 22 for 5 luminotrons 21.The line of every pair of light idol is parallel to the axis of coding print wheel 1.Some electro-optical packages and coding print wheel be assembling alternately, constitutes the photoelectric coding of long number under drives, as Fig. 2, shown in Figure 3.
Electro-optical package is fixed, and character wheel rotates.During reading of data, infrared light is sent in the luminotron energising.Be in the arc groove 11 (the light all-pass is crossed) as luminotron, photosensitive tube light income maximum then, its state is 1; Be in beyond the arc groove 11 (light by) as luminotron, photosensitive tube light income minimum then, its state is 0; Be in line segment 13,14 as luminotron, then the photosensitive tube light income is placed in the middle, and its state is a or b (photosensitive tube light income upper middle and non-1 state are a, and photosensitive tube light income lower middle and non-0 state are b).Its whole coded system is seen Fig. 4.
So, the cylinder of each coding print wheel is divided into 30 12 covering of the fans of spending angles by 30 group codings, is printed with ten numerals of 0-9 of using for artificial reading on the character wheel cylinder successively, and each numeral accounts for 3 equal angles covering of the fans, the corresponding unique a kind of state of each covering of the fan.In the corresponding three state of each numeral, preceding a kind of state representation should numeral excessively arrive display window, and the 2nd kind of state representation should numeral have been stablized and be in display window, and three state represents that this numeral has begun to the high-order digit carry.After each digital block was divided into three state, the carry problem of handling sense data had just had physical basis.Adopted the coding print wheel of said structure, can be at any time, no matter character wheel counter is in any position, need not any presupposed information just can be accurately with the demonstration numerical value converting digital electric signal of character wheel counter.Read circuit and only need when reading, to provide power supply.
