Embodiment
Below in conjunction with description of drawings the utility model is described in further detail: as shown in Figure 1, the utility model specifically is made up of counter character wheel 1, black and white sign disk 2, sensor circuit board 3 and digital signal processing circuit plate 5.Ten numerals of 0-9 are arranged on the counter character wheel 1, be evenly distributed on counter character wheel 1 periphery, the central angle between the numeral is 36 °, sees Fig. 2 (a).Black and white sign disk 2 divides ten districts corresponding to the ten number strokes of the 0-9 on the counter character wheel 1, and the central angle in each district is 36 °, and 0 ° of-180 ° of fan types zone is a black on the black and white sign disk 2, and 180 ° of-360 ° of fan types zones are white, see Fig. 2 (b).Black and white sign disk 2 is fixed on the counter character wheel 1, sees Fig. 2 (c).5 reflection-type infrared tubes (S1, S2, S3, S4, S5) (4) are arranged on the sensor circuit board 3, be 36 ° of angle circular arcs each other and arrange (or being 72 ° of angle circular arcs arrangements), they are concentric with the counter number wheel shaft, see Fig. 3 (a) and Fig. 3 (b).The black and white sign disk 2 that is fixed on the counter character wheel 1 rotates synchronously with counter character wheel 1, zones of different on 5 reflection-type infrared tubes (optoelectronic transceiver pipe), the 4 corresponding black and white sign disks 2 on the sensor circuit board 3, therefore character wheel 1 rotates in different angles, 5 reflection-type infrared tubes on the sensor circuit board 3 have different reactivenesses, sensor circuit board 3 outputs are pointed to corresponding 5 binary coded signals of numeral with counter character wheel 1, and 5 pairs of 5 binary combination coded signals of digital signal processing circuit plate are deciphered and conversion process.
Principle of work of the present utility model: a bit can be represented 2 kinds of states, i.e. " 0 " and " 1 ", reflection-type infrared tube 4 is a photoelectric sensor, when the Infrared that luminotron sends projects on the black and white sign disk 2, if reflection spot is on black region, because black absorption light, infrared light can not reflex on the receiving tube, then receiving tube ends, and it is output as high level " 1 "; When reflection spot during at white portion, then receiving tube is saturated, is output as low level " 0 ".The physical location that 10 numerals are arranged on the counter character wheel 1,5 numeric areas are set at black, other 5 numeric areas are set at white, therefore, need on the sensor circuit board 35 infrared tubes 4 can identification and counting machine character wheel 1 on the physical location of 10 numerals.When counter character wheel 1 rotates, black and white sign disk 2 rotates synchronously with counter character wheel 1,5 infrared tubes (S1, S2, S3, S4, S5) 4 have different duty (saturated or by) respectively, sensor circuit board 3 outputs are pointed to corresponding 5 the binary combination coded signals of numeral with counter character wheel 1, see shown in Fig. 4 (a) and Fig. 4 (b).So respectively corresponding ten 5 binary combination sign indicating numbers of 0 to 90 number of counter window reading, see shown in Fig. 5 (a) and Fig. 5 (b), with Fig. 5 (a) (0) is example, counter window reading is " 0 ", 5 infrared tube S1, S2, S3, S4, S5 The corresponding area all are black, and the output state combinational code of 5 infrared tubes is " 11111 "; If counter window reading is " 3 ", the zone of S1, S2 correspondence is that the zone of black, S3, S4, S5 correspondence is a white, and then the output state combinational code of 5 infrared tubes is " 00011 ", sees shown in Fig. 5 (a) (3).5 binary combination code tables of counter character wheel 0 to 90 number correspondence are seen Figure 10 (a) and Figure 10 (b).
The utility model has designed special wheel digital recognition structure, and 10 numerals of 10 corresponding counter character wheels " 0-9 " of 5 binary combination sign indicating numbers are seen Figure 10 (a) and Figure 10 (b) combination code table.This structure has well solved wrong identification appears in counter character wheel 1 at two digital intersections problem, as can see from Figure 5, counter character wheel 1 moves two digital intersections, only exist 1 infrared tube black, intersection entering or leaving between the white region, therefore only can produce the binary combination sign indicating number of one of them number in these two numerals, and can not produce other the number the binary combination sign indicating number, so, adopt this special wheel digital recognition structure, turn to the critical place of two-digit at counter character wheel 1 and just error code can not occur, this also is a unique distinction of the present utility model.
According to the recognition principle of counter wheel digital of the present utility model, another embodiment of the present utility model: as shown in Figure 6, form by counter character wheel 1, sensor circuit board 3 and digital signal processing circuit plate 5.Ten numerals of 0-9 are arranged on the counter character wheel 1, be evenly distributed on counter character wheel 1 periphery, angle between the numeral is 36 °, 360 ° of circumference in wheel digital face one side are set to black and white logo area 6, promptly 0 ° of-180 ° of circular arc is the black designation band, 180 ° of-360 ° of circular arcs are the white marker band, 5 reflection-type infrared tubes (S1, S2, S3, S4, S5) 4 on the sensor circuit board 3, install along counter character wheel 1 external arc, be 36 ° of angle circular arcs each other and arrange, they are concentric with the counter number wheel shaft.The wheel digital recognition method of this structure and preceding a kind of the identical of black and white sign disk mode that have, the binary combination sign indicating number of output are seen Figure 10 (a) combination code table.
Above-mentioned is the recognition principle of a digit counter wheel digital, mechanical counter generally is made up of a plurality of character wheels, the package assembly of embodiment one is: black and white sign disk 2 is separately fixed on each counter character wheel 1, between per two character wheels and the outside of most significant digit character wheel, a sensor circuit board 3 need be installed respectively; The package assembly of embodiment two is: sign black and white district 6 on each counter character wheel 1, in the external arc outside of each character wheel, a sensor circuit board 3 need be installed respectively.The shared digital signal processing circuit plate 5 of multidigit mechanical counter, sensor circuit board 3 is fixed on the digital signal processing circuit plate 5, and digital signal processing circuit plate 5 is fixed on the mechanical counter support, sees Fig. 7, shown in Figure 8.
Wheel digital recognition technology of the present utility model is when using, may be because of the gauging table inner structure, the difference in space, cause black and white sign disk 2 to be fixed on angle on the counter character wheel 1 setting of black and white mark region 6 (or on the counter character wheel) difference, and sensor circuit board 3 relative installation is different, then sensor circuit board 3 will produce 5 different binary combination sign indicating numbers, so different structure of the present utility model, different positions, it also is different that its counter character wheel 1 points to 5 corresponding binary combination sign indicating numbers of numeral, but regardless of black and white sign and sensor circuit board relative installation, can obtaining counter character wheel 1, to point to numeral corresponding, also be 5 unique binary combination coded signals, can decipher and be converted to the reading value of character wheel by 5 pairs of combinational codes of digital signal processing circuit plate.
Directly reading with transmitting device of meter counter numeral is simple in structure, realizes can not powering at ordinary times easily, only when the needs reading, just needs power supply.
