Description
Technical Field
The invention relates to the technical field of intelligent tape measures, in particular to an invisible ink Gray code belt and an intelligent tape measure.
Background
The gray code belongs to reliable coding and is a coding mode with minimized errors. Because, although the natural binary code can be converted directly to an analog signal by a digital-to-analog converter, in some cases, for example, every digit of the binary code changes from 3 to 4 decimal digits, a large spike current pulse can be generated by the digital circuit. Gray code does not have this disadvantage, and only one bit changes when it transitions between adjacent bits. It greatly reduces the confusion of logic from one state to the next. Since only one bit is different between two adjacent code groups in the code, in the conversion of linear displacement amount to digital amount for direction, when the linear displacement amount is slightly changed (and the digital amount is possibly changed, the gray code is changed by only one bit, which is more reliable than the case of simultaneously changing two or more bits in other codes, i.e. the possibility of error is reduced.
Gray code disks are mostly adopted for detection or counting in the prior art, and the phenomenon of brush jumping or brush leakage often occurs when the Gray code disks are read by a coder or an electric brush device, namely, the phenomenon of counting error is caused because the electric brush device bounces over a certain Gray code due to the fact that the rotating speed of the electric brush device is too high, and the Gray code is not beneficial to use. Meanwhile, the Gray code disc is arranged in the intelligent tape measure body, and occupies a large internal space, so that the device is large in size. Meanwhile, in the prior art, if the scales are directly arranged on the tape, the tape is easy to copy and has poor anti-counterfeiting performance.

Detailed Description
The invention provides a hidden ink Gray code strip and an intelligent measuring tape, and the invention is further described in detail below in order to make the purpose, the technical scheme and the effect of the invention clearer and more clear. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1-2, fig. 1 is a schematic view of a front side of a tape body of the gray code tape in an explicit state, fig. 2 is a schematic view of a back side of the tape body of the gray code tape in an explicit state, the gray code tape includes a tape body 100 and gray codes 110 disposed on the front side and/or the back side of the tape body 100, the gray codes 110 are 2-9 gray codes, and the gray codes 110 are repeatedly disposed on the tape body 100 by infrared invisible ink according to a designated period. In this way, the gray codes are arranged on the tape body 100 by adopting invisible ink, and the gray codes are repeatedly arranged on the tape body 100 according to a specified period instead of directly arranging length scales on the tape, so that the tape is not easy to copy and has good anti-counterfeiting property.
In particular implementations, the invisible ink is an anti-stokes ink. The anti-Stokes ink is invisible infrared excited ink, is in a invisible state under the condition of not being excited by infrared light, emits visible light under the excitation of 980nm infrared light, can present different colors of green, blue, yellow and the like, contains rare earth elements, can absorb a plurality of long-wave radiation with low energy, and emits high-energy short-wave radiation after being subjected to multi-photon addition, so that infrared light invisible to human eyes can be changed into visible light, and is also called as an infrared up-conversion material or infrared excited ink, and the luminescence process is also called as an infrared visible process. This phenomenon of short wavelength (higher energy) photons from excitation by long wavelength (lower energy) photons is called anti-stokes luminescence, and thus the ink is also called anti-stokes ink.
Further, the tape body 100 is provided with length scales. Therefore, a user can intuitively obtain the measurement length through the length scale and can also read the measurement length through the Gray code reading device. Thus, when the scale is worn, the measurement length can be read by a Gray code reading device; when the gray code of the invisible ink fails, the measurement length can be directly obtained through the length scale.
Further, the gray code 110 includes a first sub-gray code 111 corresponding to binary number 1 and a second sub-gray code 112 corresponding to binary number 0.
Referring to fig. 1 and fig. 2 again, the first sub-gray code 111 is a first background invisible ink rectangular silk-screen layer with a width of 1-600mm and capable of reflecting yellow light under excitation of 980nm infrared light. Most preferably, the width of the first sub-gray code 111 is 2 mm. The second sub-gray code 112 is a second base color invisible ink rectangular silk screen printing layer which reflects blue light under excitation of 980nm infrared light and is 1-600mm in width. Most preferably, the width of the second sub-gray code 112 is 2 mm. The first sub gray codes 111 are set as first background color invisible ink rectangular silk-screen layers, and the second sub gray codes 112 are set as second background color invisible ink rectangular silk-screen layers only for increasing the color difference of the two sub gray codes, so that a reading device of a gray code belt can conveniently and accurately read the current gray codes.
The specific implementation is not limited to the above manner, and it is only required that the color difference between the first sub gray code corresponding to the binary number 1 and the second sub gray code corresponding to the binary number 0 is higher than a specified color difference threshold, for example, the first sub gray code 111 is a yellow-background rectangular silk-screen layer, and the second sub gray code 112 is a green-background rectangular silk-screen layer.
Further, as shown in fig. 1 and 2, at least one linear type gray code channel 120 is disposed on both sides of the tape body 100, and a plurality of first sub-gray codes 111 and second sub-gray codes 112 are disposed on the gray code channel 120. The gray scale channel 120 is only used to limit the placement of the gray scale 110 on the tape body 100. For example, 1 gray code channel 120 with the length of 1.5m and the width of 5mm is arranged on the tape body 100, meanwhile, the first sub-gray code 111 is a first base color invisible ink rectangular silk-screen printing layer with the width of 2mm and the height of 5mm, the second sub-gray code 112 is a second base color invisible ink rectangular silk-screen printing layer with the width of 2mm and the height of 5mm, and then 750 gray codes can be arranged on the gray code channel 120 along the length direction. If only one gray track 120 is provided, only 1-bit gray can be provided on the tape body 100, and the practical application is not so large, so that at least one linear gray track 120 is provided on the front surface and/or the back surface of the tape body 100 in the specific implementation.
If all the gray code channels 120 are arranged on the same surface of the tape body 100, the width of the tape body 100 can be increased, the tape body 100 is wound and arranged at the inside of the intelligent tape, the height of the tape outlet is increased, namely the thickness of the intelligent tape body is increased, so that the size of the whole intelligent tape is increased, and the tape is inconvenient to carry by a user.
If the gray track 120 is arranged on the front side and the back side of the tape body 100, the width of the tape body 100 can be reduced, which is beneficial to reducing the volume of the intelligent tape measure and is convenient for a user to carry.
For example, when the tape body 100 has a total of 6 parallel Gray tracks 120, N Gray tracks (where 1. ltoreq. N.ltoreq.6, and N is a positive integer) may be provided on the front side, and (6-N) Gray tracks may be provided on the back side. Since the widths of the gray tracks 120 are all equal and fixed, and the sum of the widths of the gray tracks 120 on the same side of the tape body 100 plus the width of the non-gray track area is equal to the width of the tape body 100, when the difference between the number of the gray tracks 120 on the front side of the tape body 100 and the number of the gray tracks 120 on the back side of the tape body 100 is 1 or completely equal, the width of the tape body 100 can be reduced to the minimum value.
Preferably, as shown in fig. 1 and 2, the tape body 100 has 3 gray tracks on the front and back surfaces thereof from bottom to top, and each gray track is provided with one of 6 gray codes. A lower three-position gray code channel is arranged on the front surface of the tape body 100, the lower three-position gray code channel corresponds to the lower three position of the 6-position gray code, and the lower three-position gray code channel is respectively marked as a first position gray code channel 121, a second position gray code channel 122 and a third position gray code channel 123; the back of the tape measure tape body 100 is provided with three high gray code channels, the three high gray code channels correspond to three high gray codes in the 6 gray codes, and the three high gray code channels are respectively marked as a fourth gray code channel 124, a fifth gray code channel 125 and a sixth gray code channel 126. In specific implementation, the first gray track 121, the second gray track 122 and the third gray track 123 on the front surface of the tape body 100 can be interchanged at will, and the fourth gray track 124, the fifth gray track 125 and the sixth gray track 126 on the back surface of the tape body 100 can be interchanged at will.
Each of the 6-bit gray scales in the present invention is provided on the same surface of the tape body 100 in the longitudinal direction (i.e., in the width direction of the tape body 100). If the front surface of the tape body 100 is sequentially provided with a third gray code channel 123, a second gray code channel 122 and a first gray code channel 121 from bottom to top, and the back surface of the tape body 100 is sequentially provided with a fourth gray code channel 124, a fifth gray code channel 125 and a sixth gray code channel 126 from bottom to top, if there is a six gray code 111111, wherein the first bottom invisible ink rectangular screen printing layer (2 mm in width) corresponding to the highest position (i.e. the 6 th position) 1 is arranged on the sixth gray code channel 126, the first bottom invisible ink rectangular screen printing layer (2 mm in width) corresponding to the next highest position (i.e. the 5 th position) 1 is arranged on the fifth gray code channel 125, the first bottom invisible ink rectangular screen printing layer (2 mm in width) corresponding to the 4 th position 1 is arranged on the fourth gray code channel 124, and the first bottom invisible ink rectangular screen printing layer (2 mm in width) corresponding to the 3 rd position 1 is arranged on the third gray code channel 123, the first background color invisible ink rectangular silk-screen layer (width is 2 mm) corresponding to the next lower position (namely, the 2 nd position) 1 is arranged on the second gray code channel 122, and the first background color invisible ink rectangular silk-screen layer (width is 2 mm) corresponding to the lowest position (namely, the 1 st position) 1 is arranged on the first gray code channel 121.
The first base color invisible ink rectangular silk screen layer corresponding to the highest position (namely, the 6 th position) 1, the first base color invisible ink rectangular silk screen layer corresponding to the next highest position (namely, the 5 th position) 1 and the first base color invisible ink rectangular silk screen layer corresponding to the 4 th position 1 are arranged in alignment along the longitudinal direction (namely, along the width direction of the measuring tape body 100). The first base color invisible ink rectangular silk-screen layer corresponding to the 3 rd position 1, the first base color invisible ink rectangular silk-screen layer corresponding to the next lower position (i.e. the 2 nd position) 1 and the first base color invisible ink rectangular silk-screen layer corresponding to the lowest position (i.e. the 1 st position) 1 are longitudinally (i.e. along the width direction of the tape measure body 100) aligned. Since the period of the 6-bit gray code is 64 (i.e. the power of 6 of 2), see table 1-table 4, the 6-bit gray code of a whole period is set to have a length of 32 × l (where l is the width of the first sub-gray code 111 or the second sub-gray code 112, e.g. 2 mm).

TABLE 4
Therefore, the Gray code is directly arranged on the tape and is repeatedly arranged according to the designated period instead of directly arranging the length scales on the tape, the Gray code on the tape can be read by the reading device, the traditional scale reading mode is replaced, and the reading stability is enhanced. Meanwhile, the gray code is directly arranged on the tape body, so that a gray code disc does not need to be additionally arranged when the tape is wound into the tape body, and the size of the tape is reduced.
Based on the gray code strip, the invention further provides an intelligent measuring tape with a gray code strip, as shown in fig. 3 and 4, the intelligent measuring tape with a gray code strip comprises the gray code strip and a gray code reading device 200 for reading the reading of the gray code strip.
When the front and back of the tape body 100 of the intelligent tape measure are provided with 3 gray code channels 120 from bottom to top, gray code reading devices 200 corresponding to the gray code channels 120 one to one are further provided, and the irradiation range of infrared light emitted by each gray code reading device does not exceed the height range of each gray code channel 120. Specifically, the first gray code reading device faces the first gray code channel 121, the second gray code reading device faces the second gray code channel 122, the third gray code reading device faces the third gray code channel 123, the fourth gray code reading device faces the fourth gray code channel 124, the fifth gray code reading device faces the fifth gray code channel 125, and the sixth gray code reading device faces the sixth gray code channel 126. The six Gray code reading devices are respectively connected with corresponding I/O ports in an MCU control chip in the intelligent tape measure body.
In specific implementation, the gray code reading device 200 includes an infrared emitting module (which emits infrared light with a wavelength of 980 nm) and a visible light intensity detecting module. The reflection light of each gray code on the tape body 100 to the infrared light emitted by the infrared emission module is determined by whether the current gray code is the first sub-gray code or the second sub-gray code. If the current gray code is the first sub gray code, after infrared light emitted by the infrared emission module is reflected by the first sub gray code, the visible light intensity detection module acquires the light intensity of the reflected light and decodes the light intensity into 1; if the current gray code is the second sub gray code, the visible light intensity detection module acquires the light intensity of the reflected light and decodes the light intensity into 0 after the infrared light emitted by the infrared emission module is reflected by the second sub gray code.
Because 3 gray code reading devices are respectively arranged on two sides of the tape body 100, if the infrared receiving and transmitting devices on two sides of the tape body 100 are completely opposite, when infrared rays emitted by the infrared receiving and transmitting device on one side of the tape body 100 transmit through the tape body 100, the infrared receiving result of the gray code reading device 200 on the other side is changed, and the measuring result is influenced.
In order to ensure the accuracy of the measurement result, the start point of the gray track on the front surface of the tape body 100 needs to be displaced from the start point of the gray track on the back surface of the tape body 100. When the tape measure body 100 is in an initial state without being pulled out, the first gray code reading device faces the starting point of the first gray code channel 121, the second gray code reading device faces the starting point of the second gray code channel 122, the third gray code reading device faces the starting point of the third gray code channel 123, the fourth gray code reading device faces the starting point of the fourth gray code channel 124, the fifth gray code reading device faces the starting point of the fifth gray code channel 125, and the sixth gray code reading device faces the starting point of the sixth gray code channel 126. Since the starting points of the gray tracks on both sides of the tape body 100 are misaligned, positions facing the first, second, and third gray reading devices distributed on one side of the tape body 100 are misaligned by a predetermined distance with respect to positions facing the fourth, fifth, and sixth gray reading devices distributed on the other side of the tape body 100. In specific implementation, the displacement distance between the starting point of the gray track on the front surface of the tape body 100 and the starting point of the gray track on the back surface of the tape body 100 is 3-10 mm. Preferably, the displacement distance between the start point of the gray track on the front surface of the tape body 100 and the start point of the gray track on the back surface of the tape body 100 is 5.5 mm.
When the tape body 100 is pulled, the Gray code reading device 200 and an MCU control chip which is arranged in the intelligent tape body and connected with the Gray code reading device 200 detect the times n of the repeating cycle length when the tape body 100 is pulled and the offset delta L in the current repeating cycle length together, and then the L = n LTThe actual measurement length L can be obtained through calculation by + delta L, so that the length can be accurately measured, and the measurement error is reduced. Particularly, the first sub-gray codes and the first sub-gray codes with certain widths are arranged on each gray code channel of the tape, so that the gray codes on the tape can be read by the reading device, the traditional scale reading mode is replaced, and the reading stability is enhanced.
In summary, the invisible ink gray code strip and the intelligent tape provided by the invention have the advantages that the gray codes are arranged on the tape by adopting the invisible ink, and the gray codes are repeatedly arranged on the tape according to the specified period instead of directly arranging the length scales on the tape, so that the tape is difficult to copy and has good anti-counterfeiting performance. And moreover, the tape measure can also read Gray codes on the tape measure belt through the reading device, so that the traditional scale reading mode is replaced, and the reading stability is enhanced. Meanwhile, the gray code is directly arranged on the tape body, and a gray code disc does not need to be additionally arranged when the tape is wound and arranged in the intelligent tape body, so that the size of the tape is reduced.
It is to be understood that the invention is not limited to the examples described above, but that modifications and variations may be effected thereto by those of ordinary skill in the art in light of the foregoing description, and that all such modifications and variations are intended to be within the scope of the invention as defined by the appended claims.
