Problems solved by technology

Therefore, the particles that need to be detected in the invention are distributed between 1nm-2000nm, and the wavelength of incident light that can cause Rayleigh scattering of these corresponding particles needs to be between 10nm-20000nm. The spectrum of these wavelengths, especially in the deep ultraviolet part, traditional methods difficult to manufacture
[0007] In addition, in traditional spectral analysis methods, prisms or lenses are mostly used to adjust the optical path, and the materials of the lenses are limited in the range of light-transmitting wavelengths. There are few lenses on the market that can transmit deep ultraviolet light or far-infrared light.

Embodiment 1

[0020] Such as figure 1 , 2 As shown, the very early fire safety and fire early warning detection device of the present invention is realized in this way, the composite light source or ray radiation source a is placed behind the baffle b in a closed space A (box), and there is a Single slit c, the single slit c on the baffle b can not only make the compound light source diffract when it passes through, but at the same time, the width of the single slit on the baffle b should not be greater than 10000 times the diameter of the smallest particle to be detected, In the closed space A on the other side of the single slit c on the baffle b, array photosensors d and e are respectively arranged on the side and front of the diffracted light of the wavelength that can cause Rayleigh scattering of ultra-small particles, and the array on the side The sensing surface of the photoelectric sensor d is parallel to the light, the sensing surface of the front array photoelectric sensor e is f...

Embodiment 2

[0022] Such as Figure 4 As shown, in order to reduce air pollution to the array photoelectric sensor, the part of the channel where the array photoelectric sensor d, e is set is the decapitation channel, and the baffle b in front of the decapitation channel is provided with an opening, so that the air inlet and the compound hair The space of the light source or the radiation source a communicates with the space, and at the same time, the space where the compound light source or the radiation source a is set communicates with the channel with the fan h. In this way, the outside air can enter the part of the channel where the array photosensors d and e are arranged as the broken end channel, so that the change of the amount of ultra-small particles in the air can be brought into the broken end channel, and at the same time, a large amount of continuous air can be prevented. The flow passes through the broken end channel to avoid continuous accumulation of pollutants and pollute...

Abstract

The invention discloses a fire control safety fire early-warning detection method and a fire control safety fire early-warning detection device capable of discovering fire risks and predicting fire-breaking materials at a very early stage. The fire control safety fire early-warning detection device comprises a composite light source, a baffle plate with a single slit, an air passage, a photoelectric sensor, a central processing module and a network module, wherein light rays with different wavelengths are diffracted and split by means of the baffle plate with the single slit, and irradiate ultra-small particles passing through the air passage along with the flowing air; the content and change law of the ultra-small particles in the air are detected by detecting intensity of the sheltered light rays with different wavelengths and intensity of Rayleigh scattering light on mote particles of different diameters by means of the photoelectric sensor; and the effects of sensing a potential fire disaster at the very early stage and predicting the fire-breaking material are achieved through detecting fire-breaking mote concentration in the atmosphere by utilizing a big data machine learningmethod. Compared with the prior art, the fire control safety fire early-warning detection method and the fire control safety fire early-warning detection device have the advantages of being simple instructure, and capable of discovering the potential fire disaster at the very early stage and predicting the fire-breaking materials.

Description

technical field [0001] The invention relates to an early warning detection technology for fire protection. Background technique [0002] In the current fire warning and monitoring equipment, most of the products are based on smoke sensing or some kind of gas sensing. When a fire occurs, there are many types of gas and smoke released, and the fire sensor cannot cover all situations. As a result, conventional early warning mechanisms are prone to false alarms. Moreover, when significant indicators such as smoke have risen, the fire has basically formed, and there is not much time left for people to extinguish the fire or escape. Therefore, how to detect fire hazards as early as possible before visible smoke is produced is the key to prevention. [0003] When fighting a fire, firefighters often need to investigate and determine the type and nature of the burning substance before they can use the corresponding fire extinguishing method in a targeted manner. For example, if oi...
