Abstract

L'invention concerne un bouchon de mesure de température utilisé en association avec un système de mesure de température à bouchon d'unité principale d'anneau, comprenant un corps de bouchon (100), une extrémité du corps de bouchon (100) étant pourvue d'une rainure de montage d'insert principal (110) ; un insert principal (200) disposé dans la rainure de montage d'insert principal (110), l'insert principal (200) étant utilisé pour faciliter le montage du corps de bouchon (100) ; et une puce de mesure de température passive sans fil (300) disposée dans le corps de bouchon (100) et utilisée pour mesurer la température interne d'une unité principale d'anneau, renvoyer un signal de température à une antenne de réception externe, et générer une alimentation de travail en détectant un signal d'onde électromagnétique externe. Comparativement à la structure classique composée d'un inlay supérieur et d'un inlay inférieur, le bouchon de mesure de la température réduit considérablement le nombre d'inserts métalliques et diminue les coûts. La température interne de l'unité principale d'anneau peut être mesurée au moyen de la puce de mesure de température passive sans fil (300) ; parallèlement, une alimentation électrique de fonctionnement peut être obtenue directement en détectant le signal d'onde électromagnétique externe, et l'autorecherche de puissance ou la recherche de puissance par couplage de champ électrique et d'autres modes sont inutiles pour obtenir l'alimentation électrique, ce qui prolonge considérablement la durée de vie.
