Mfumo mpya wa kutambua halijoto na mfumo wa kengele, kazi, mwongozo kamili-INNO

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. Mfumo wa kengele ya moto unaotumika kwenye ghala la bomba la kina ni ugunduzi wa halijoto ya macho ya nyuzi laini, with distributed fiber optic sensors based on Raman scattering and optical time domain reflectometry. Ina faida za upinzani mkubwa wa kuingiliwa kwa umeme, unyeti mkubwa, na gharama ya chini. Hata hivyo, ili kukabiliana na sifa za mazingira ya unyevu, mabomba tata, na mahitaji ya juu ya kuzuia moto wa nyumba ya sanaa ya bomba ya kina, utendakazi wa mfumo wa ugunduzi wa halijoto ya macho ya nyuzi laini unahitaji kuboreshwa zaidi.

Katika uchambuzi wa joto (moto) katika mifumo mbalimbali ya uhandisi, njia za kupima joto, sehemu za kipimo cha joto kilichotawanyika na kisichoendelea, umbali wa kipimo cha joto, usahihi wa kipimo cha joto, uchimbaji wa ishara za joto, na uchambuzi wa eneo la vituo vya kupokanzwa ni viungo muhimu. Vifaa vya kawaida vya kupima halijoto vina udhaifu kama vile kutambua moja kwa moja, usahihi wa joto la chini, nafasi ya fuzzy, kiwango cha majibu ya joto la chini, umbali mfupi wa kipimo cha joto, na ujenzi mgumu. Tengeneza mfumo wa kipimo cha joto cha nyuzi macho unaosambazwa ambao unakidhi mahitaji kulingana na halijoto halisi (moto) ufuatiliaji wa ishara za miradi mikubwa ya uhandisi, combined with optical technology and electronic circuit technology. The more continuous the data collected by instruments for monitoring temperature (moto) 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. Kupitia ufuatiliaji wa muda mrefu na uchambuzi wa joto (moto), a lot of information about temperature (moto) can be obtained. Kwa hiyo, whether temperature (moto) can be monitored continuously and accurately for a long time largely determines the accuracy and timeliness of temperature (moto) 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, umeme, and computers. The system utilizes the Raman scattering effect of laser fiber and the principle of optical time domain reflectometry (OTDR) 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; Nyuzi za macho zinazohisi joto include fixed temperature sensing optical fibers and differential temperature sensing optical fibers.
