The necessity of using fiber optic temperature measurement system in fire warning system

शहरीकरण के निरंतर विकास के साथ, पावर ग्रिड निर्माण में अधिक से अधिक केबल और हाई-वोल्टेज स्विचगियर हैं, और फाल्ट की संभावना भी बढ़ती जा रही है. According to fault statistics, it was found that the failure rate of cables and switches has been increasing year by year. इसके अतिरिक्त, अधिकांश अग्नि दुर्घटनाएँ उच्च तापमान के कारण होती हैं. इसलिए, before a fire occurs, timely and accurate monitoring of temperature changes in cables and switchgear and issuing alarms allows users sufficient time to take corresponding measures, which is particularly important for avoiding accidents or causing fires. तथापि, the current main use is traditional temperature measurement systems, where the detection points of the sensor distribution are intermittent, और केवल जांच जांच के संपर्क में आने वाले बिंदुओं का ही पता लगाया जा सकता है. पता लगाने की सीमा छोटी है, and the detection signal output is a weak electrical signal, जो विद्युत चुम्बकीय हस्तक्षेप के प्रति अत्यधिक संवेदनशील है; Using circuits as signal channels requires particularly high insulation requirements for high-voltage equipment, रखरखाव और मरम्मत को कठिन बनाना. तापमान प्रणालियों के व्यापक परीक्षण के लिए उपयुक्त नहीं है.

Fiber Bragg Grating Temperature Sensing Fire Detection System

Fiber optics have been widely used in automatic fire detection प्रणाली, especially in narrow spaces such as tunnels and comprehensive pipe galleries. तथापि, due to the continuous improvement of traditional inspection methods that only focus on the characteristics of easy construction and laying in space, and neglect the importance of temperature detection systems in monitoring, this has led to inconvenient monitoring, उच्च रखरखाव लागत, and even system paralysis due to long-term disrepair, posing a fire hazard to people’s lives. To address the aforementioned deficiencies in existing technologies, FJINNO has made significant breakthroughs in the structure of its fiber optic fire warning system products, effectively addressing the aforementioned issues.

1. Being able to accurately locate the exact location of temperature changes and achieve precise positioning, a precise fiber optic linear temperature detection system is formed, which integrates computer, फाइबर ऑप्टिक संचार, फाइबर ऑप्टिक सेंसिंग, fiber optic transmission, optoelectronic control and other technologies. Based on the temperature measurement principle of fiber optic backscatter with temperature changes, OFDR advanced technology is used to monitor the feedback information on the fiber optic in real time through temperature sensing optical cables, measure the temperature changes at various points on the fiber optic, and monitor the temperature status of the detected area in real time;

2. Suitable for long-distance monitoring, the system is very simple and reliable, maintenance free, and extremely convenient to install. It can be suspended and laid in a straight line without affecting the installation and expansion of new equipment;

3. लंबी सेवा जीवन, intrinsic safety of optical fiber, कोई विद्युत चुम्बकीय हस्तक्षेप नहीं, comprehensive intelligent judgment without false alarms, and it is not charged, suitable for special dangerous situations.
