(ZH) 一种接触状态监测装置
Abstract: front page image
(EN)The invention relates to the field of engineering, and in particular, to a contact state monitoring device. The contact state monitoring device comprises a packaging member (1) having a disc shape, and comprising a sensing optical fiber (2) disposed therein. By considering requirements of cement board installation and pavement techniques and disadvantages of several conventional pressure measurement techniques, and using Brillouin optical time-domain analysis (BOTDA), the embodiment provides a novel, real-time, distributed monitoring, and BOTDA-based monitoring device to monitor a contact state of a cement board bottom.
(FR)L'invention concerne le domaine de l'ingénierie, et en particulier un dispositif de surveillance d'état de contact. Le dispositif de surveillance d'état de contact comprend un élément d'emballage (1) possédant une forme de disque, et comprenant une fibre optique de détection (2) disposée en son sein. En tenant compte des exigences des techniques de chaussée et d'installation de plaque de ciment et des inconvénients de plusieurs techniques de mesure de pression classiques, et à l'aide d'une analyse de domaine temporel optique de Brillouin (BOTDA), le mode de réalisation fournit une nouvelle surveillance répartie en temps réel, et un dispositif de surveillance basé sur BOTDA en vue de surveiller un état de contact d'un fond de plaque de ciment.
