Rotary optical fiber temperature-sensing fire detector

Abstract

The invention relates to the technical field of fire detectors, in particular to a rotary optical fiber temperature-sensing fire detector which comprises a plurality of temperature-sensing control hosts. The temperature-sensing control hosts are connected with temperature-sensing optical cables and arranged in a control box, the control box is fixed in a box body, the temperature-sensing control host is connected with a power module through a wire, the temperature-sensing control host detects temperature changes through a temperature-sensing optical cable, the temperature-sensing control host is connected with a wireless transmission module through a signal line, and the wireless transmission module is in signal connection with a console. The console collects detection signals returned by the temperature-sensing control hosts arranged at all positions, the console is connected with a route generation module through a signal line, and the route generation module automatically generates an escape route according to fire information fed back by all the temperature-sensing control hosts. The fire happening position can be conveniently judged, and an escaper can be assisted to escape quickly.

Description

technical field [0001] The invention relates to the field of fire detectors, in particular to a rotary optical fiber temperature-sensitive fire detector. Background technique [0002] The working principle of the optical fiber line type temperature-sensing fire detector is simple, that is, the detection optical fiber is laid in the space to be tested, and the temperature-sensing optical fiber host emits the laser beam into the detection optical cable, and collects in real time the reflected light along the optical fiber, with the scene The Raman (Raman) scattered light of real-time temperature information, the temperature-sensing optical fiber host analyzes and processes these optical signals, so as to obtain the temperature distribution information on the entire optical fiber. The temperature information is compared with the preset alarm parameter value, and when the alarm condition is met, the optical fiber host sends out a fire alarm sound and light indication, and can ou...

AI Technical Summary

Problems solved by technology

The optical fiber temperature-sensitive fire detector in the prior art is inconvenient to judge the location of the fire, so it is inconvenient to plan the escape route reasonably, which affects the rescue and escape time
