Taking a six-bit valid counting wheel as an example, the error reading that may occur between the first rotating wheels such as 7899.99 and 7900.00 is analyzed. Dividing a full six-bit word wheel into two line groups according to the multi-bit counting wheel carry principle, starting from the lowest bit counting digit, taking each three-bit counting digit as one line group, taking each two-bit counting digit wheel as a rotating wheel group, taking a low-bit digit such as 0 in the same rotating wheel group, and dividing the low-bit digit into three areas according to one tenth (36 degrees) of the whole circle: the high-order digit is divided into three digit areas, namely an area 0a, an area 0b and an area 0 c: region 0a, region 0b, region 0 c. Taking the carry partition determination of 7899.99 as an example: when the area 9c and the area 0a are in the same area, the effective counting value is carry: 7900.00, when zone 9a and zone 0a, the effective value of the count is the no carry count: 7899.99. taking the carry partition determination of 6888.95 as an example: the first decimal digit 9 is located at the position of x b, the second decimal 5 is located at the position of x c, no carry occurs in the rotating wheel set, and the effective count is 6888.96. Because the number in the same rotating wheel group is: b zone is static counting bit, absolute value reading has no carry judgment range, and misreading risks can not occur; and when the total number of counting digits is divided by 3 and the remainder is not zero, the remainder (1 or 2) is taken as an independent line group, and the carry judgment of the adjacent position is still carried out according to the rotating wheel group. The reading division mode of the line group grouping can effectively reduce the problem that the linearity of the carry character wheel effective indication digit is poor due to too many counting digits, transmission display lag is inevitably generated due to mechanical manufacturing and other problems, the caused character wheel line is in a diagonal line state, the software processing process is influenced, or deviation, misreading and other conditions are caused for the judgment of a correct value, and the requirement of mechanical manufacturing precision on character wheel carry can be effectively reduced by increasing the design of the carry judgment processing software of the line group. In the counting wheel, the low-order counting passes through the last one tenth of a turn, the high-order word wheel is carried by means of a special carry gear which is distributed on the circumference of the word wheel and meshed with the high-order word wheel, the transmitting and receiving signals of the counting and positioning of the word wheel are identified by means of special software through the light transmission and shading of fan-shaped or special-shaped holes which are distributed on the radial direction of the word wheel along the circular ring area, and a designed circuit reads unique binary digital signals of high and low levels instantly.
Example 2: as shown in FIG. 9, cdefgh is in a static count wheel with no carry occurring, and the electronic decision confirms that it is in region # b. ab is in the digital zone with carry generation, and the electronic judgment b is in the zones 4c and 9 c. Two secondary judgments exist among the three line groups, whether the continuous three-bit digital low-level line group exists or not is in the carry combining area, and the carry does not exist in the line group combining area. From this the correct indication is electronically read: 555555.50.
example 3: as shown in FIG. 10, fgh is in the static count wheel with no carry occurring, and the electronic judgment confirms that it is in region # b. abcde is located in the carry generation digit region, the electronic judgment b region is located in the regions 9c and 0b, the c region is located in the regions 9c and 0a, and the d region is located in the regions 8c and 9 b. Two secondary judgments exist among the three line groups, whether a continuous three-bit digital low-bit line group exists or not is judged in a carry combining area, a d area and an abc line group are judged, all three-bit carries exist in abc, and the d area is 8c and 0 a. From this the correct indication is electronically read: 555590.00.
