Title:
ELECTRONIC MEASURING DEVICE AND METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/061878
Kind Code:
A1
Abstract:
An electronic measurement device and method thereof is provided. The electronic measurement device includes a casing assembly (10), a reel (34), and a tape blade (36) wound on the reel (34). The electronic measurement device further includes incremental encoder barcodes (50), absolute encoder barcodes (40), an optical reader module (603), and a processor (702). The incremental encoder barcodes (50) are readable for generating incremental measuring data indicating a linear extension of the tape blade (36). The absolute encoder barcodes (40) are readable for generating absolute measuring data indicating absolute position on the tape blade (36). The processor (702) is operable to correct the incremental measuring data on the basis of the absolute measuring data to output a measured value. The electronic measurement device and method thereof has advantage in various aspects such as high accuracy, synchronization, technical simplicity, ease of manufacturing, assembling, operation, maintenance and carrying around.
