Background technology

Mechanical counters such as existing water meter, ammeter, gas meter, though it is simple in structure, with low cost, its continuous data can't be realized copying automatically and get and handle automatically, brings great inconvenience for user and supvr.For this reason, people have also designed the dynamo-electric treating apparatus of some mechanical counters, the patent No. as the applicant's application is 99229267.0, name is called " a kind of intelligent treating apparatus of mechanical flow meter ", and the patent No. is 200520074412.6, name is called " a kind of optical processing device of mechanical counter ", though they can both convert the metering result of mechanical counter electric signal to and carry out acquisition process, but owing to can't see the realtime graphic of mechanical counter, whether the copy reading result correctly can't know, in case copy reading makes mistakes, with the dispute of initiation with the user.Recently, people have also developed the shooting treating apparatus of mechanical counter, but because the prior mechanical counter is only seen a digital part on some when carry, and can't see complete numeral, therefore adopt common digit recognition method often to make mistakes, recognition accuracy is very low, still fails to be applied.

Summary of the invention

For overcoming the deficiencies in the prior art part, the utility model provide a kind of rational in infrastructure, accuracy is high, the shooting treating apparatus of good reliability, manufacturing and mechanical counter easy to use.

The technical scheme that its technical matters that solves the utility model adopts is: comprise circulation binary coding bar and single-chip microcomputer; On the periphery of each counting scale of mechanical counter, be equipped with the circulation binary coding bar of the garden annular more than five or five; Above circulation binary coding bar, camera is installed, and camera links to each other with single-chip microcomputer.

Above-mentioned circulation binary coding bar is divided into the garden segmental arc of 30 five equilibriums, is constituting 30 groups of circulation binary codings more than five or five on each counting scale, and the one in the 0-9 numeral on per three groups of circulation binary codings and the counting scale is corresponding.

In circulation binary coding bar,, be printed as white and black respectively corresponding to 1 and 0 in the circulation binary coding, otherwise or.

Above-mentioned circulation binary coding bar or be divided into the garden segmental arc of 40 or 50 five equilibriums is constituting 40 or 50 groups of circulation binary codings more than five on each counting scale, the one in the 0-9 numeral on per four groups or five groups and the counting scale is corresponding.

Above-mentioned camera and single-chip microcomputer place in the printed board of being fixed in the mechanical counter top.

The beneficial effects of the utility model are: simple in structure, encoding strip is reasonable in design, can convert the metering result of mechanical counter to electronic digital signal exactly, the measuring accuracy height, good reliability, and can see the realtime graphic of mechanical counter, make and easy to use, applied widely, for copying automatically of the continuous data of mechanical counter got and management brings great convenience.

Among the figure: 1 is that housing, 2 is that printed board, 3 is that camera, 4-1 are that an individual counting scale, 4-2 are that ten counting scales, 4-3 are that hundred counting scales, 4-4 are that kilobit counting scale, 4-a are that circulation binary coding bar, 5 is that single-chip microcomputer, 6 is that counting scale axle, 7 is that driving gear, 8 is that carry gear shaft, 9 is the carry gear.

Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

The utility model embodiment is with the example that is applied as on existing four mechanical counters.Four mechanical counters mainly are made up of housing 1, counting scale, counting scale axle 6, carry gear 9, carry gear shaft 8 and driving gear 7; Four by the black engineering plastics make, ten, hundred, kilobit counting scale 4-1,4-2,4-3,4-4 be loaded on the counting scale axle 6 successively, one end of counting scale axle 6 is contained on the sidewall of housing 1 inner chamber, and the other end is equipped with driving gear 7 after passing another sidewall of housing 1.Three carry gears 9 are loaded on the carry gear shaft 8, and lay respectively between four counting scales, and the two ends of carry gear shaft 8 are fixed on the two side of housing 1 inner chamber.A driving gear 7, counting scale axle 6 and a position counting scale 4-1 rotate synchronously, when individual position counting scale 4-1 rotates a week, drive ten counting scale 4-2 by carry gear 9 and rotated for 1/10th weeks, and the like, by low level to high position transmission step by step.Described shooting treating apparatus comprises circulation binary coding bar 4-a, camera 3 and single-chip microcomputer 5; At the circulation binary coding bar that is equipped with five garden annulars on the periphery of each counting scale of mechanical counter (being to have only a difference between adjacent two groups of binary codings) 4-a, and above-mentioned circulation binary coding bar 4-a is divided into the garden segmental arc of 30 five equilibriums, black is circulation binary-coded 0, white is circulation binary-coded 1 (otherwise or), promptly constitute 30 groups five circulation binary coding, the one in the 0-9 numeral on per three groups five circulation binary coding and the counting scale is corresponding.Referring to Fig. 2, the numeral on the counting scale 0 is corresponding to 00000,00001,00,011 three group five circulation binary coding as can be seen, other numeral and the like.Camera 3 is installed above mechanical counter, and above-mentioned camera 3 links to each other with single-chip microcomputer 5.For just manufacturing, above-mentioned camera 3 is fixed in the printed board 2 with single-

chip microcomputer

5, and 2 of printed boards are fixed on mechanical counter housing 1 inwall.

When needs are copied the metering as a result time of getting mechanical counter, by five the circulation binary codings on four counting scale garden side faces of single-chip microcomputer 5 control cameras 3 picked-up mechanical counters and the image of corresponding numeral, by single-chip microcomputer 5 five circulation binary codings on each counting scale garden side face are discerned, thereby drawn pairing numeral on the counting scale.This numeral can cause outside data collector by lead with certain coded format, because each numeral of the 0-9 on the counting scale is all corresponding to three groups five circulation binary coding, thereby can reflect the physical location of counting scale more accurately, it is more accurate to copy the metering result who gets, and get the realtime graphic that mechanical counter is also absorbed in metering in the result copying, whether accurately come into plain view for copying the metering result who gets.And, owing to adopt identification to bar code to replace in the prior art Direct Recognition, thereby the copy reading accuracy rate is significantly improved, particularly when digital especially obvious when imperfect to numeral.

Above-mentioned circulation binary coding bar 4-a also can be more than five (as: 6 or 7) be on the garden side face of a unit each counting scale of being printed in mechanical counter respectively; Circulation binary coding bar 4-a also can be divided into the garden segmental arc of 40 or 50 five equilibriums, promptly constitute 40 groups (or 50 groups), six (or seven s') circulation binary coding, the one in the 0-9 numeral on six (or seven) circulation binary codings of per four groups (or five groups) and the counting scale is corresponding.
