Embodiment Construction
[0049] The structure diagram of the self-synchronizing barcode displacement sensor of the present invention is as follows figure 1 As shown, the self-synchronizing barcode displacement sensor of the present invention includes a reading box 3, a tape 1, and a specific one-dimensional barcode 2 printed on the tape. The reading box 3 is separated from the ruler tape 1 by a certain distance, and is kept parallel all the time, and the movement direction of the reading box 3 is consistent with the length direction of the ruler tape 1 . Among them, the reading box 3 includes a display screen 4, a function button 6, a microUSB data interface 7, and a signal indicator light 8, and a barcode reading device 5 (a CCD camera in this embodiment) is installed below, and there are two on the left and right sides respectively. Install fixing hole 9.
[0050] In this embodiment, the tape 1 is made of PC film, which has good flexibility, is suitable for installation on a flat or curved surface,...
