फाइबर ब्रैग झंझरी तापमान माप और संवेदन आग अलार्म, सिस्टम विशेषताएँ और पैरामीटर

वही 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. फिर भी, पारंपरिक निरीक्षण विधियों के निरंतर सुधार के कारण जो केवल आसान निर्माण और अंतरिक्ष में बिछाने की विशेषताओं पर ध्यान केंद्रित करते हैं, the importance of temperature detection systems in monitoring has been ignored, resulting in inconvenient monitoring, उच्च रखरखाव लागत, और यहां तक ​​कि लंबे समय तक ख़राबी के कारण सिस्टम पक्षाघात भी, लोगों के जीवन के लिए आग का खतरा पैदा करना. To address the multiple defects caused by existing technologies, our product has made significant breakthroughs in system architecture, effectively solving the problems raised above. वर्तमान में, 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.

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, फाइबर ऑप्टिक संचार, फाइबर ऑप्टिक सेंसिंग, फाइबर ऑप्टिक ट्रांसमिशन, फोटोइलेक्ट्रिक नियंत्रण और अन्य प्रौद्योगिकियां. 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. लंबी दूरी की निगरानी के लिए उपयुक्त, प्रणाली बहुत सरल और विश्वसनीय है, रखरखाव मुक्त, and easy to install. नए उपकरणों की स्थापना और विस्तार को प्रभावित किए बिना इसे निलंबित किया जा सकता है और एक सीधी रेखा में रखा जा सकता है;
3. लंबी सेवा जीवन, inherently safe optical fiber, विद्युत चुम्बकीय हस्तक्षेप से प्रभावित नहीं, झूठे अलार्म के बिना व्यापक बुद्धिमान निर्णय, and it is not electrified, suitable for special hazardous situations.

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.
