سنسورهای دمای فیبر نوری INNO ,سیستم های مانیتورینگ دما.
را fiber optic grating temperature sensing fire detection system has been widely used in automatic fire detection systems, especially for narrow spaces such as tunnels and comprehensive pipe galleries. با این حال, due to the continuous improvement of traditional inspection methods that only focus on the characteristics of easy construction and laying in space, the importance of temperature detection systems in monitoring has been ignored, resulting in inconvenient monitoring, high maintenance costs, and even system paralysis due to long-term disrepair, posing a fire hazard to people’s lives. To address the multiple defects caused by existing technologies, our product has made significant breakthroughs in system architecture, effectively solving the problems raised above. در حال حاضر, China’s nuclear power plants are in a period of rapid development and construction, and the protection system of nuclear power plants using nuclear fuel reactors as energy is particularly important, among which the fire detection, alarm and linkage system is also a very important system.
اندازه گیری دمای توری فیبر براگ and Sensing Fire Alarm System
1. Being able to accurately locate the exact location of temperature changes, reflecting small temporal and spatial differences in frequency to achieve precise positioning, thus forming a precise fiber optic linear temperature detection system. It integrates computer, fiber optic communication, حسگر فیبر نوری, fiber optic transmission, photoelectric control and other technologies. Based on the temperature measurement principle of fiber optic backscattering with temperature changes, فناوری پیشرفته OFDR برای نظارت بر اطلاعات بازخورد روی کابل فیبر نوری در زمان واقعی اتخاذ شده است, تغییرات دما را در نقاط مختلف کابل فیبر نوری اندازه گیری کنید, و وضعیت دمای منطقه شناسایی شده را در زمان واقعی نظارت کنید;
2. مناسب برای نظارت از راه دور, سیستم بسیار ساده و قابل اعتماد است, بدون تعمیر و نگهداری, و نصب آسان. بدون تأثیر بر نصب و گسترش تجهیزات جدید می توان آن را معلق و در یک خط مستقیم گذاشت;
3. عمر طولانی, فیبر نوری ذاتا ایمن, تحت تأثیر تداخل الکترومغناطیسی قرار نمی گیرد, قضاوت هوشمند جامع بدون هشدارهای کاذب, و برقی نیست, مناسب برای موقعیت های خطرناک خاص.
