In addition, by the uncertain point that the reflective working lining of this runner is obtained, there is one at the most.
Further combined with Fig. 5 and respective embodiments the utility model is further described below.
Shown in Fig. 3-2,4-2,4 groups of photoelectric sending and receiving sensor groups 200 are carried out the sensitization data collection to the reflective working lining 150 of 4 supporting runners respectively, reflective areas 151 wherein is arranged between the 2-6 of character wheel 141, non-reflective areas window 154 is arranged between 3 and 4, corresponding non-reflective areas 153 is arranged on that reflective areas window 152 is arranged between 8 and 9 between the 7-1 of character wheel 141, this moment 4 reflective working linings of runner that 4 groups of photoelectric sending and receiving sensor groups are gathered data mode, " 1999 " that show with the visual numerical aperture 130 of above-mentioned Fig. 3-1 are corresponding.The high-order non-reflective areas window 154a of high-order as we can clearly see from the figure character wheel correspondence, the low level non-reflective areas window 154d corresponding with the low level character wheel width of comparing has increased.
Shown in ginseng Fig. 3-2, the data mode of 4 reflective working linings of runner of 4 groups of photoelectric sending and receiving sensor group collections, because each photoelectric sending and receiving sensor 210 is when Information Monitoring, corresponding all is reflective areas or non-reflective areas accurately, there are not reflective areas window and non-reflective areas window to be gathered, so and after truth table 300 comparisons, just directly draw " 1999 " of visual numerical aperture 130 demonstrations of above-mentioned Fig. 3-1, this moment, these data did not have uncertain point as can be seen, and the numerical value of reading is exact value.
Shown in ginseng Fig. 4-1 and Fig. 4-2,4 groups of photoelectric sending and receiving sensor groups are gathered the data mode of 4 reflective working linings of runner, and we are called 4 pairing numerical value of runner from left to right: first, second, the 3rd, the 4th.When runner by " 1999 " state, we analyze one by one to the demonstration situation of each below when turning to " 2000 ":
First, owing to produced carry, reading between this group photoelectric sending and receiving sensor R0-R4 is at this moment: 1, (1 or 0), 0,0,1,1.5 position of the truth table 300 among this just corresponding Fig. 1, the reading of R1 is uncertain, and what R4 read is uncertain some decision state value, because first correspondence is high-order character wheel, the width of corresponding non-reflective areas window 154a is the wideest in these four, so the easiest being determined of this uncertain point.
Second, also produced carry, 0,0,1,0, (1 or 0) reading between this moment this group photoelectric sending and receiving sensor R0-R4 is:, 9.5 position of the truth table 300 among this just corresponding Fig. 1, what R2 read is uncertain some decision state value, and the reading of R4 is uncertain, because the character wheel of second correspondence is only second to most significant digit, the width of corresponding non-reflective areas window also is only second to the width of the non-reflective areas window of most significant digit correspondence, so this uncertain point more easily is determined.
The 3rd, its principle and above-mentioned deputy just the same, just the width of corresponding non-reflective areas window is only second to the width of the non-reflective areas window of second correspondence, is not just giving unnecessary details at this.
The 4th, its principle and above-mentioned second and third just the same, just the width of corresponding non-reflective areas window is only second to the width of the non-reflective areas window of the 3rd correspondence, the width of corresponding non-reflective areas window is minimum in the technical solution of the utility model, so the 4th is these four of being difficult for judging uncertain point most.
If between 3 and 4, do not have non-reflective areas window as can be seen from above-mentioned four place readings, and there is not the reflective areas window between 8 and 9, first may be read as 1 or 2 so, second, three, four all might be read as 9 or 0 respectively, just may be misread as this moment: 1999,1990,1909,1900,1099,1009,1090,1000,2999,2990,2909,2900,2099,2009,2090,2000 totally 16 kinds may situations, we are provided with reflective areas window and non-reflective areas window now, as long as the packets of information of gathering contains uncertain point, just must collect reflective areas window or non-reflective areas window one, by just judging, be in nondeterministic statement this moment like this.
But problem is, though we are provided with reflective areas window or non-reflective areas window, because the width of window is not done further qualification, same like this problem of makeing mistakes can appear detecting, particularly should be for 1999 or 2000 but because also there be the carry problem in a high position as the original numerical value of above-mentioned situation, just might read is 2999 or 1000, will cause irremediable error like this, and the utility model the reflective areas window that high-order character wheel is corresponding with the low level character wheel or the width of non-reflective areas window, the high position that just can guarantee that is set to successively decrease successively enters uncertain some determinating area at first, leave uncertain some determinating area at last, thereby make that the accuracy of reading is more secure.
As mentioned above, when determining when comprising at uncertain,, shown in Fig. 4-1,4-2, will be final reading directly with 1999 before the carry with directly reading last of carry, the error with reading has dropped to minimum like this.
More than be to description of the present utility model and non-limiting, based on other embodiment of the utility model thought, all among protection domain of the present utility model.
