Itu 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. Walau bagaimanapun, 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. Pada masa ini, 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.
Fiber Bragg Grating Temperature Measurement 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, fiber optic sensing, fiber optic transmission, photoelectric control and other technologies. 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. Suitable for long-distance monitoring, the system is very simple and reliable, Penyelenggaraan Percuma, and easy to install. It can be suspended and laid in a straight line without affecting the installation and expansion of new equipment;
3. Long service life, inherently safe optical fiber, tidak terjejas oleh gangguan elektromagnet, comprehensive intelligent judgment without false alarms, 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.
