New temperature sensing fire detection and alarm system, कार्य, संपूर्ण मार्गदर्शिका

The integrated pipe gallery, subway, underground complex and other underground engineering are unified into the urban underground space planning, एक सामान्य और व्यापक विकास का निर्माण करना, and the fire prevention requirements of the integrated pipe gallery are gradually increasing. व्यापक पाइप गैलरी पर लागू फायर अलार्म सिस्टम मुख्य रूप से रैखिक फाइबर ऑप्टिक तापमान का पता लगाने वाला है, with distributed fiber optic sensors based on Raman scattering and optical time domain reflectometry. इसमें मजबूत विद्युत चुम्बकीय हस्तक्षेप प्रतिरोध के फायदे हैं, उच्च संवेदनशीलता, और कम लागत. तथापि, आर्द्र वातावरण की विशेषताओं के अनुकूल होने के लिए, जटिल पाइपलाइन, और व्यापक पाइप गैलरी की उच्च अग्नि रोकथाम आवश्यकताएँ, रैखिक फाइबर ऑप्टिक तापमान पहचान प्रणाली के प्रदर्शन में और सुधार करने की आवश्यकता है.

In the analysis of temperature (आग) in various engineering systems, temperature measurement methods, बिखरे हुए और असंतत तापमान माप बिंदु, तापमान माप दूरी, तापमान माप सटीकता, तापमान संकेतों का निष्कर्षण, and location analysis of heating points are important links. पारंपरिक तापमान माप उपकरणों में लाइव डिटेक्शन जैसी कमजोरियां हैं, कम तापमान सटीकता, fuzzy positioning, कम तापमान प्रतिक्रिया दर, कम प्रभावी तापमान माप दूरी, और कठिन निर्माण. Develop a distributed linear fiber optic temperature measurement system that meets the requirements based on the actual temperature (आग) monitoring signals of major engineering projects, ऑप्टिकल प्रौद्योगिकी और इलेक्ट्रॉनिक सर्किट प्रौद्योगिकी के साथ संयुक्त. The more continuous the data collected by instruments for monitoring temperature (आग) 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. तापमान की दीर्घकालिक निगरानी और विश्लेषण के माध्यम से (आग), a lot of information about temperature (आग) can be obtained. इसलिए, whether temperature (आग) can be monitored continuously and accurately for a long time largely determines the accuracy and timeliness of temperature (आग) 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 (ओटीडीआर) 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.
