Title
(EN) ELECTRONIC MEASURING DEVICE AND METHOD THEREOF
(FR) DISPOSITIF DE MESURE ÉLECTRONIQUE ET PROCÉDÉ ASSOCIÉ
Abstract
(EN)
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.

L'invention concerne un dispositif de mesure électronique et un procédé associé. Le dispositif de mesure électronique comprend un ensemble boîtier (10), une bobine (34) et une bande (36) enroulée sur la bobine (34). Le dispositif de mesure électronique comprend en outre des codes à barres de codeur incrémental (50), des codes à barres de codeur absolu (40), un module lecteur optique (603) et un processeur (702). Les codes à barres de codeur incrémentiel (50) sont lisibles pour générer des données de mesure incrémentielles indiquant une extension linéaire de la bande (36). Les codes à barres de codeur absolu (40) sont lisibles pour générer des données de mesure absolues indiquant une position absolue sur la bande (36). Le processeur (702) est utilisable pour corriger les données de mesure incrémentielles sur la base des données de mesure absolues pour délivrer en sortie une valeur mesurée. Le dispositif de mesure électronique et le procédé associé présentent des avantages dans divers aspects tels qu'une précision élevée, une synchronisation, une simplicité technique, une facilité de fabrication, d'assemblage, de fonctionnement, de maintenance et de transport.
