The integrated pipe gallery, subway, underground complex and other underground engineering are unified into the urban underground space planning, forming a common and comprehensive development, and the fire prevention requirements of the integrated pipe gallery are gradually increasing. The fire alarm system applied to the comprehensive pipe gallery is mainly linear fiber optic temperature detection, with distributed fiber optic sensors based on Raman scattering and optical time domain reflectometry. It has the advantages of strong electromagnetic interference resistance, 고감도, and low cost. 그렇지만, in order to adapt to the characteristics of humid environment, complex pipelines, and high fire prevention requirements of the comprehensive pipe gallery, the performance of the linear fiber optic temperature detection system needs to be further improved.
In the analysis of temperature (fire) in various engineering systems, temperature measurement methods, 흩어져 있고 불연속적인 온도 측정 지점, 온도 측정 거리, 온도 측정 정확도, 온도 신호 추출, and location analysis of heating points are important links. 기존의 온도 측정 장치에는 실시간 감지와 같은 약점이 있습니다, 낮은 온도 정확도, fuzzy positioning, 낮은 온도 응답률, 짧은 유효 온도 측정 거리, 그리고 어려운 건설. Develop a distributed linear fiber optic temperature measurement system that meets the requirements based on the actual temperature (fire) monitoring signals of major engineering projects, 광학 기술 및 전자 회로 기술과 결합. The more continuous the data collected by instruments for monitoring temperature (fire) in an effective area, the more realistic and accurate the actual signals obtained. This requires a device with super computing power and high-speed acquisition and processing. 장기간의 온도 모니터링 및 분석을 통해 (fire), a lot of information about temperature (fire) can be obtained. 그러므로, whether temperature (fire) can be monitored continuously and accurately for a long time largely determines the accuracy and timeliness of temperature (fire) warning and alarm.
The recoverable linear fiber optic temperature sensing fire detection and alarm system is a new type of temperature sensing fire detection and alarm system developed internationally in recent years. It integrates laser technology, fiber optic transmission and sensing technology, optoelectronic technology, weak signal detection technology, high-speed transient data acquisition and computer processing technology, and is a high-tech product that integrates optics, mechanics, electronics, and computers. The system utilizes the Raman scattering effect of laser fiber and the principle of optical time domain reflectometry (증권 시세 표시기) to achieve temperature measurement and position determination of continuous spatial temperature fields. Although existing fire detectors can achieve basic fire alarms, they have low measurement accuracy, few measurement points, high false alarm rates, and poor reliability of information data.
The recoverable linear fiber optic differential temperature fire detector consists of a temperature sensing fiber optic, a fiber optic temperature intelligent analyzer, a connector, a central processing unit, and a fire controller. The temperature sensing fiber optic is connected to the fiber optic temperature intelligent analyzer; Fiber optic temperature intelligent analyzer and connector connection; Connect the connector to the central processing unit; Connect the central processing unit to the fire controller; Temperature sensing optical fibers include fixed temperature sensing optical fibers and differential temperature sensing optical fibers.
