Wireless flame detection system

Abstract

The invention provides a system comprising a wireless flame detector. The system comprises the wireless flame detector, wherein the wireless flame detector is capable of forming a communication network through a wireless transmission circuit, and communicating with a data monitoring center to transmit detected fire data and an alarm signal to the data monitoring center; and the wireless flame detector comprises an infrared sensor with a wavelength of 2 microns, an ultraviolet sensor with a wavelength of 2 nanometers, a sensor signal processing circuit, a pre-positioned digital signal processing circuit, a processing chip and a signal transmission circuit. According to the wireless flame detection system, the setting of the sensors selects a certain angle, the detection regions of the sensors are at a certain distance, the coverage detection of the fire surface is realized, the accuracy and stability of fire detection are improved, the acquired signals are subjected to analog filtering and digital filtering, white noise and stored auxiliary sensor signals are introduced in the digital filtering, thus noise in the background of the scene environment can be filtered out, the digital signal processing circuit can process frequency domain data of signals, the fire detection signals are accurate, the wireless transmission circuit can form the network , and the wired and wireless transmission methods can be switched according to the scene situations.

Description

technical field [0001] The detection system of the invention is suitable for the field of industrial fire protection systems, and particularly relates to the field of fire detection and alarm. Background technique [0002] Fire detection system is also called flame detection system, which is used for fire detection, alarm and activation of fire-fighting equipment in industrial and public places. The detector is suitable for various types: oil depots, wine depots, hangars, chemical equipment places, military equipment places, liquefied gas stations, power stations, etc. When fires germinate, there is no smoldering stage or less smoldering stage, and the direct generation of open flames is the main method. place. Because any object has the ability to continuously radiate, absorb, and reflect electromagnetic waves. The radiated electromagnetic waves are different in each band, that is, they have a certain spectral distribution. This spectral distribution is related to the ch...
