Table 4
It can be seen that, as Gray code is set directly on tape band, and repeat to arrange Gray code by the cycle of specifying on tape band, rather than directly length scale is set on tape band, 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.Simultaneously because using directly arranging Gray code on tape measure band body, wind setting to tape measure sheet it is internal when without the need for additional again, Gray's code-disc is set, reduce the volume of tape measure.
Based on above-mentioned Gray code band, present invention also offers a kind of Gray code band Intelligent measuring tape, as shown in Figure 3 and Figure 4, including described Gray code band, also include for reading the Gray code reading device 200 of the Gray code tape reading.
When the front and the back side of the tape measure band body 100 of the Intelligent measuring tape are provided with 3 Gray's code channels 120 from bottom to up, it is additionally provided with and 120 one-to-one Gray code reading device 200 of Gray's code channel, and the range of exposures of infrared light that sends of each Gray code reading device is without departing from the altitude range of each Gray's code channel 120.Specifically, first Gray code reading device is just to first Gray's code channel 121, second Gray code reading device is just to the second Gray code channel 122,3rd Gray code reading device is just to the 3rd Gray's code channel 123,4th Gray code reading device is just to the 4th Gray's code channel 124,, just to the 5th Gray's code channel 125, the 6th Gray code reading device is just to the 6th Gray's code channel 126 for 5th Gray code reading device.Above-mentioned six Gray code reading devices connect the corresponding I/O mouths in the intrinsic MCU control chips of Intelligent measuring tape respectively.
When being embodied as, the Gray code reading device 200 includes infrared transmission module（Which sends the infrared light that wavelength is 980nm）With visible ray light-intensity test module.On tape measure band body 100, the reflected light of the infrared light that each Gray code is sent to infrared transmission module is that the first sub- Gray code or the second sub- Gray code are determined by current Gray code.If current Gray code is the first sub- Gray code, after the infrared light that infrared transmission module sends is by the first sub- Gray code reflection, the light intensity of reflected light is obtained by visible ray light-intensity test module and 1 is decoded as；If current Gray code is the second sub- Gray code, after the infrared light that infrared transmission module sends is by the second sub- Gray code reflection, the light intensity of reflected light is obtained by visible ray light-intensity test module and 0 is decoded as.
As the both sides of tape measure band body 100 are respectively arranged 3 Gray code reading devices, if the infrared transceiver device of 100 both sides of tape measure band body is completely just right, the infrared transmitting that then infrared transceiver device of 100 side of tape measure band body sends excessively the tape measure band body 100 when, the infrared light-receiving result of the Gray code reading device 200 of opposite side can be caused to change, affect measurement result.
In order to ensure the accuracy of measurement result, the starting point of 100 positive Gray's code channel of the tape measure band body and the starting point of Gray's code channel at 100 back side of tape measure band body need to be shifted to install.Due to when tape measure band body 100 is the state that the first beginning and end are drawn out, starting point of the first Gray code reading device just to first Gray's code channel 121, starting point of the second Gray code reading device just to the second Gray code channel 122, starting point of the 3rd Gray code reading device just to the 3rd Gray's code channel 123, starting point of the 4th Gray code reading device just to the 4th Gray's code channel 124, starting point of the 5th Gray code reading device just to the 5th Gray's code channel 125, starting point of the 6th Gray code reading device just to the 6th Gray's code channel 126.Because there is dislocation in the starting point of the two-sided Gray's code channel of tape measure band body 100, thus be distributed in the first Gray code reading device, the second Gray code reading device and the 3rd Gray code reading device of 100 side of tape measure band body just to position relative to be distributed in the 4th Gray code reading device, the 5th Gray code reading device and the 6th Gray code reading device of 100 opposite side of tape measure band body just to position have the dislocation of certain distance.When being embodied as, the starting point of 100 positive Gray's code channel of the tape measure band body is 3-10mm with the starting point dislocation distance of Gray's code channel at 100 back side of tape measure band body.Optimal, the starting point of 100 positive Gray's code channel of the tape measure band body is 5.5mm with the starting point dislocation distance of Gray's code channel at 100 back side of tape measure band body.
When tape measure band body 100 is during being pulled, by Gray code reading device 200, and detect jointly tape measure band body 100 frequency n of repetition period length and offset Δ L in current repetition period length when pulled with the MCU control chips for being arranged on Intelligent measuring tape sheet in vivo and be connected with Gray code reading device 200, 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 first sub- Gray code with one fixed width and the first sub- Gray code are arranged on each Gray's code channel of tape, the Gray code on tape band can be read by reading device, traditional scale reading manner is instead of, is enhanced the stability of reading.
In sum, invisible printing ink Gray code band of the present invention and Intelligent measuring tape, by Gray code is arranged on tape band using invisible printing ink, and repeat to arrange Gray code by the cycle of specifying on tape band, rather than directly length scale is set on tape band, and it is difficult to be imitated, antifalsification is good.But also 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.Simultaneously because using directly arranging Gray code on tape measure band body, wind setting to Intelligent measuring tape sheet it is internal when without the need for additional again, Gray's code-disc is set, reduce the volume of tape measure.
It should be appreciated that the application of the present invention is not limited to above-mentioned citing, for those of ordinary skills, can be improved according to the above description or be converted, all these modifications and variations should all be belonged to the protection domain of claims of the present invention.
