Wireless fire detector for early fire recognition

Abstract

The invention relates to a fire alarm, in particular to an early fire recognition detector based on the combination of a sensor array technique and a ZigBee wireless technique. The detector is achieved by a sensor array module, a mode recognition module and the ZigBee wireless technique, wherein the sensor array module consists of a plurality of paths of gas sensors and temperature sensors; and after the processing by a signal processing module, a fire recognition algorithm is adopted to detect and recognize the gas generated at an early stage of fire; a ZigBee sends the result of the recognition, the temperature and the smoke intensity to a monitoring center in a wireless mode; and a computer of the monitoring center achieves the positioning of a fire source point and the description of a three-dimensional space of a temperature field and a smoke field. The detector has the advantages of the early fire recognition, the positioning of the fire source point, and visual descriptions of the temperature field and the smoke field.

Description

Technical field [0001] The invention relates to a fire alarm, in particular to an early fire identification detector based on the combination of sensor array technology and ZigBee wireless technology. Background technique [0002] After a fire occurs, it has the characteristics of difficult evacuation, difficult rescue, and rapid fire development. Once a fire occurs, it will often cause a large number of casualties and huge property losses, so the early detection of the fire is particularly important. [0003] Although the fire alarm systems and fire-fighting facilities installed in large and medium-sized buildings and public places in our cities have gradually become popular and improved, the problems exposed in the actual use process have become increasingly prominent. Mainly manifested in two aspects: First, the traditional fire detector is mainly composed of a single sensor (smoke sensor, temperature sensor, etc.), the fire point detection, through the threshold to determine ...

Problems solved by technology

But the fly in the ointment is that the use of photoelectricity, smoke and temperature composite fire detectors still cannot realize the early prediction of fire and the location of the fire source, and there are certain false alarms (for example, cigarettes), and there are certain limitations in the appropriate places. Sex (such as a dance hall, there is more smoke)
