اندازه‌گیری دمای توری فیبر براگ و سنسور اعلام حریق, مشخصات و پارامترهای سیستم

این 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. اما, با توجه به بهبود مستمر روش های بازرسی سنتی که تنها بر ویژگی های ساخت و ساز آسان و تخمگذار در فضا تمرکز دارد, the importance of temperature detection systems in monitoring has been ignored, resulting in inconvenient monitoring, هزینه های نگهداری بالا, و حتی فلج سیستم به دلیل خرابی طولانی مدت, خطر آتش سوزی برای زندگی مردم. 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, ارتباط فیبر نوری, حسگر فیبر نوری, انتقال فیبر نوری, کنترل فوتوالکتریک و سایر فناوری ها. Based on the temperature measurement principle of fiber optic backscattering with temperature changes, advanced OFDR technology is adopted to monitor the feedback information on the fiber optic cable in real time, measure the temperature changes at various points on the fiber optic cable, and monitor the temperature condition of the detected area in real time;
2. مناسب برای نظارت از راه دور, سیستم بسیار ساده و قابل اعتماد است, تعمیر و نگهداری رایگان, 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, inherently safe optical fiber, تحت تأثیر تداخل الکترومغناطیسی قرار نمی گیرد, قضاوت هوشمند جامع بدون هشدارهای کاذب, and it is not electrified, مناسب برای موقعیت های خطرناک خاص.

Fiber Bragg Grating Linear Temperature Fire Detector is a fire alarm device based on the Bragg Grating temperature sensing principle, which can detect the temperature changes along the fiber Bragg Grating sensing points in real time and achieve multi-level alarm functions; This instrument comes with a LCD screen and touch buttons, making it convenient for on-site reset and self checking operations.

The fiber optic grating linear temperature sensing fire detector processor has passed various tests and inspections in GB16280-2014 “Linear Temperature Sensing Fire Detector” and obtained the corresponding 3C certificate. The temperature sensor connected has been tested by relevant national departments and obtained a high-level explosion-proof certificate.
