Alin ang pinakamahusay na fiber optic fire monitoring system manufacturing plant-INNO

Fiber Optic Fire Monitoring System

Ibinahagi ang fiber optic temperature sensing system may tumpak na sukat, matatag na pagganap, malakas na anti-interference na kakayahan, at maaaring mapagtanto ang malayuang pagtuklas ng temperatura. Ang video-type na fire detector ay maaaring malaman nang mas intuitive at mabilis ang lokasyon ng apoy, ang laki ng apoy, ang bilis ng sunog at direksyon ng pagkalat ng usok, ang sitwasyon ng mga nakulong na tao at iba pang impormasyon, upang ang mga tauhan ng pagsubaybay ay makapag-react nang mabilis upang makontrol ang pag-unlad ng sunog sa pinakamabuting posibleng panahon, at upang maiwasan ang mga maling alarma na dulot ng panlabas na kapaligiran. Ang firefighting linkage system ay upang gumawa ng emergency response sa sunog nang mabilis at ipatupad ang pagsagip sa mga tauhan, sistema ng bentilasyon at paglisan ng trapiko. Kung ang video surveillance system ay ginagamit upang madagdagan ang distributed fiber-optic temperature sensing system, at ang firefighting linkage system ay ginagamit para sa emergency response sa tunnel fires, pagkatapos ay ganap na maisasama ng sistemang ito ang mga pakinabang ng lahat ng tatlo sa isang kumpletong pagsubaybay sa sunog sa lagusan at sistema ng maagang babala sa pag-apula ng sunog.

Ayon sa mga katangian ng apoy ng isang lagusan ng isang mahabang highway, upang mapagtanto ang mahusay na pagkontrol ng apoy sa isang mahabang lagusan ng highway, ang kumpanya ay nakapag-iisa na nagsaliksik at nakabuo ng isang set ng tunnel pagsubaybay sa sunog at early warning fire fighting system. Patuloy na sinusukat ng distributed fiber-optic temperature sensing system ang temperatura sa linya ng pamamahagi, na maaaring tumpak na matukoy ang lokasyon ng fire point at ang temperatura ng bawat tindahan sa tunnel, pag-iwas sa interference ng electromagnetic waves; the video monitoring system, when receiving the alarm signal from the fiber-optic sensor, can quickly obtain the specific situation of the fire scene through the monitor, which facilitates the rapid response to the fire, effectively controls the development of the fire, and facilitates the firefighting and rescue of the fire. The fire fighting and rescue system is also convenient for fire fighting and rescue. The fire fighting linkage system can make emergency response to the tunnel fire.

The test highway tunnel consists of three sub-systems; a fiber optic temperature sensing detection system, information sharing between control rooms, and collection of data and information from on-site equipment, which is ultimately transmitted to a computer in the monitoring center, triggering the video monitoring system and the fire emergency response system.

When a fire is detected by the fiber-optic temperature sensing detection system, the monitoring video system can quickly receive the alarm signal, display the location of the fire on the screen, and then immediately activate the fire-fighting linkage system to realize fire-fighting and ventilation as well as evacuation of people inside and outside the tunnel after confirmation. In order to prove the feasibility of this tunnel fire monitoring and early warning fire fighting system, and at the same time, to improve the basis for analyzing the development pattern of the fire and the speed of smoke flow at the early stage of the fire, the ignition test was simulated. According to the “Fiber Optic Grating Temperature Sensing Fire Alarm System Design, Construction and Acceptance Specification”, the test tunnel was divided into four fire zones.

The test tunnel is divided into 4 fire zones, at 1 fiber optic sensor is set up, with a total of 10 fiber optic sensors in each fire zone, forming 40 mga punto ng pagsubaybay. One manual alarm button is installed at 50m intervals, and the alarm signal is transmitted by twisted pair cable. The fire source for the ignition test is a 0.68X0.68 m2 fire bowl, and the manual alarm signal and the temperature signal detected by the fiber optic are transmitted to the fire alarm control mainframe, and the OPC server implements the system. The ignition test shows that the system’s alarm position and temperature are accurate, the data are reliable, at mataas ang sensitivity. Sa simulate ignition test ng mahabang highway tunnel, ang pinakamabilis na oras ng alarma ng system para sa a 0.5 m2 sunog noon 10 s. Pinatunayan ng pagsubok na ito ang pagiging posible ng pagsubaybay sa sunog ng tunnel at sistema ng proteksyon sa sunog ng babala.
