Fire disaster detector and detection positioning method

Abstract

The present invention relates to a fire detector and a detection positioning method. The fire detector of the present invention comprises a real-time monitoring sensor, a horizontal positioning sensor and a vertical positioning sensor. When the real-time monitoring sensor monitors a fire signal, the horizontal positioning sensor scans at the horizontal direction and stops scanning when detecting the fire signal; then the vertical positioning sensor scans at the vertical direction and stops scanning when detecting the fire signal, so as to finish positioning an ignition point. The fire detector and the detection positioning method of the present invention utilizes an ultraviolet flame sensor to detect the occurrence of fire, can avoid the interference of sunlight, lamplight and other background light, reduce false alarm rate, and improve detection accuracy degree. The fire detector can accurately position the ignition point through the horizontal positioning sensor and the vertical positioning sensor, so as to provide accurate data for subsequent fire extinguishment and realize that extinguishing agent is accurately sprayed at the ignition point, which can prevent extinguishing agent from damaging unlighted property at the same time when saving extinguishing agent.

Description

technical field [0001] The invention relates to a fire detector, in particular to a fire detector utilizing ultraviolet light and having a positioning function, and also relates to a fire detection and positioning method. Background technique [0002] The essence of fire detection technology is to use sensors to perceive the physical phenomena in fire. According to the physical characteristics of fire, people have used dozens of physical quantity conversion effects as fire detection principles, and developed corresponding fire detectors. These fire detectors can be divided into five types: gas-sensitive, temperature-sensitive, smoke-sensitive, light-sensitive and sound-sensitive. Different fire detectors are suitable for different monitoring needs and environmental conditions. [0003] For buildings with large spaces, such as large warehouses, workshops, hangars, garages, and oil depots, etc., the internal space is high and the span is large, and the smoke diffusion at the...

Problems solved by technology

This will have two disadvantages. One is that the fire extinguishing agent, especially water or powder, will pollute the protected place, and even damage the articles stored in the protected place; , especially in large space places, the consumption of fire extinguishing agent is very large when spraying fire extinguishing agent in a large area. If the fire extinguishing effect is to be ensured, a large amount of fire extinguishing agent storage is required. The fire is not extinguished when the fire extinguishing agent has been exhausted
