Table 4
It can be seen that, knowable in 6 Gray's code tables of table 1- tables 4, the repetition period of 6 Gray codes is 64, and serial number（M+1）Gray code compared with the Gray code of serial number M（Wherein 1≤M≤63）, have and only one-bit digital there occurs change（Become 0 by 1, or be changed into 1 from 0）.If black code is designated as 0, white code is designated as 1, then by above-mentioned 64 6 Gray codes with one end of tape band 200 as starting point, sequentially print to the other end.For example by the 000000 of serial number 1, this 6 Gray codes are arranged on starting point place end, specifically by highest order in 6 Gray codes（I.e. the 6th）0 is arranged on the 6th Gray's code channel 216, by a secondary high position（I.e. the 5th）0 is arranged on the 5th Gray's code channel 215, is arranged on the 4th Gray's code channel 214 by the 4th 0, is arranged on the 3rd Gray's code channel 213 by the 3rd 0, by secondary low level（That is second）0 is arranged on second Gray code channel 212, by lowest order（I.e. first）0 is arranged on first Gray's code channel, the height of above-mentioned 6 codes is highly equal with corresponding Gray's code channel, above-mentioned 6 codes are rectangular strip, and the width of rectangular strip is 1mm, sequence number so as shown in table 1- tables 4 sequentially arranges Gray code on tape band 200, you can obtain tape band 200 as shown in Figure 3 and Figure 4.Wherein, 200 front of tape band as shown in Figure 3 is to set gradually first Gray's code channel 211, second Gray code channel 212 and the 3rd Gray's code channel 213 from top to bottom, and 200 back side of tape band as shown in Figure 4 sets gradually the 6th Gray's code channel 216, the 5th Gray's code channel 215 and the 4th Gray's code channel 214 from top to bottom.
When the front and the back side of the tape band 200 of the Intelligent measuring tape are provided with 3 Gray's code channels 210 from bottom to up, it is additionally provided with and 210 one-to-one infrared transceiver device 300 of Gray's code channel, and the range of exposures of infrared light that sends of each infrared transceiver device is without departing from the altitude range of each Gray's code channel 210.Specifically, first infrared transceiver device is just to first Gray's code channel 211, second infrared transceiver device is just to the second Gray code channel, 3rd infrared transceiver device is just to the 3rd Gray's code channel 213,4th infrared transceiver device is just to the 4th Gray's code channel 214,, just to the 5th Gray's code channel 215, the 6th infrared transceiver device is just to the 6th Gray's code channel 216 for 5th infrared transceiver device.Above-mentioned six infrared transceiver devices connect the corresponding I/O mouths in the MCU control chips in Intelligent measuring tape body 100 respectively.
As the both sides of tape band 200 are respectively arranged 3 infrared transceiver devices 300, if the infrared transceiver device of 200 both sides of tape band is completely just right, the infrared transmitting that then infrared transceiver device 300 of 200 side of tape band sends excessively the tape band 200 when, the infrared light-receiving result of the infrared transceiver device 300 of opposite side can be caused to change, affect measurement result.
In order to ensure the accuracy of measurement result, the starting point of 200 positive Gray's code channel of the tape band need to be shifted to install with the starting point of Gray's code channel at 200 back side of the tape band.Due to when tape band 200 is the state that the first beginning and end are drawn out, starting point of first infrared transceiver device just to first Gray's code channel 211, starting point of second infrared transceiver device just to the second Gray code channel 212, starting point of 3rd infrared transceiver device just to the 3rd Gray's code channel 213, starting point of 4th infrared transceiver device just to the 4th Gray's code channel 214, starting point of 5th infrared transceiver device just to the 5th Gray's code channel 215, starting point of the 6th infrared transceiver device just to the 6th Gray's code channel 216.Because there is dislocation in the starting point of the two-sided Gray's code channel of tape band 200, thus be distributed in the first infrared transceiver device, the second infrared transceiver device and the 3rd infrared transceiver device of 200 side of the tape band just to position relative to be distributed in the 4th infrared transceiver device, the 5th infrared transceiver device and the 6th infrared transceiver device of 200 opposite side of the tape band just to position have the dislocation of certain distance.When being embodied as, the starting point of 200 positive Gray's code channel of the tape band is 3-10mm with the starting point dislocation distance of Gray's code channel at 200 back side of the tape band.Optimal, the starting point of 200 positive Gray's code channel of the tape band is 5.5mm with the starting point dislocation distance of Gray's code channel at 200 back side of the tape band.
Due to being all black code and white code occur with some cycles on each Gray's code channel 210, and white code and black code are to be alternately present.The absorbance of the infrared light that black code and white code are sent to infrared transceiver device 300 is different simultaneously, specifically black code is high to the absorbance of infrared light, white code is low to the absorbance of infrared light, and less than the infrared absorption rate of black code, 0 is decoded as after the infrared light that black code is reflected back is received by infrared transceiver device 300,1 is decoded as after the infrared light that white code is reflected back is received by infrared transceiver device 300.
Therefore when tape band 200 is during being pulled, by infrared transceiver device 300, and detect jointly tape band 200 frequency n of repetition period length and offset Δ L in current repetition period length when pulled with the MCU control chips that are connected in Intelligent measuring tape body 100 and with infrared transceiver device 300 are arranged on, then by L=n*LT+ Δ L can be calculated actual measurement length L, be achieved in that and length is accurately measured, reduce measurement error.Particularly due to the black code with one fixed width and white code are arranged on each Gray's code channel of tape, it is prevented effectively from and deforms upon and caused measurement error because soft tape is stretched.
In sum, the Intelligent measuring tape that measurement length can be converted into footwear code value of the present invention, when user need to measure sole length and be converted into footwear code value, then switch the measurement pattern of Intelligent measuring tape to surveying pattern, and tape band is extracted out in vivo from Intelligent measuring tape sheet can complete measurement.And after measurement is completed, the footwear code value after the sole measurement of length reading and conversion can be retained in Intelligent measuring tape, and user can check at any time, facilitate user.Simultaneously because by Gray code is set directly on tape band, and repeat to arrange Gray code by the cycle of specifying on tape band, and each Gray code in a cycle has the black code or white code of one fixed width, the Gray code on tape band can be read by reading device, traditional scale reading manner is instead of, the stability of reading is enhanced.
