Title (EN) PHYSICAL QUANTITY MEASUREMENT SYSTEM
(FR) SYSTÈME DE MESURE DE GRANDEURS PHYSIQUES
(JA) 物理量計測システム
Abstract: front page image
(EN)This temperature measurement system (10) is provided with: an optical fiber (11) to which FBGs (21-30) are provided; a measurement device (12) connected to the optical fiber (11), and a light source that outputs incoming light to the optical fiber (11). The FBGs (21-30) have reflection spectra that are the same as each other. Also, the light source (14) outputs a broad spectrum of light including the reflection spectra of the FBG (21-30) to the optical fiber (11). The measurement device (12) detects the overall amount of light of the entire spectrum of reflection light from the FBGs (21-30), and on the basis of the overall amount of light, performs abnormality discrimination at battery cells (V1-V10), which are the sections to be measured at which each FBG (21-30) is disposed.
(FR)L'invention concerne un système de mesure de température (10) comprenant : une fibre optique (11) dans laquelle sont disposés des réseaux de Bragg sur fibre (FBG) (21-30) ; un dispositif de mesure (12) relié à la fibre optique (11) ; et une source lumineuse qui injecte la lumière émise dans la fibre optique (11). Les réseaux FBG (21-30) possèdent des spectres de réflexion identiques les uns aux autres. De même, la source lumineuse (14) délivre à la fibre optique (11) un spectre lumineux étendu qui contient les spectres de réflexion des réseaux FBG (21-30). Le dispositif de mesure (12) détecte la quantité de lumière totale de l'ensemble du spectre de lumière réfléchie des réseaux FBG (21-30) et, sur la base de cette quantité de lumière totale, effectue une discrimination d'anomalies au niveau des éléments de batterie (V1-V10), qui sont les sections à mesurer, dans chacune desquelles un réseau FBG (21-30) est disposé.
(JA) 温度計測システム10は、FBG21~30が設けられた光ファイバ11、光ファイバ11に接続される計測装置12、及び光ファイバ11に入射光を出力する光源を備えている。FBG21~30は、互いに同一となる反射帯域を有している。また、光源14は、FBG21~30の反射帯域を含む広帯域の光を光ファイバ11に出力する。計測装置12は、FBG21~30からの反射光の全体的なスペクトルの総光量を検出し、この総光量に基づいて、各FBG21~30が配置されている被計測部である電池セルV1~V10での異常判別が行われる。
