Fire-proof mask equipped with infrared imaging system

Abstract

The invention discloses a fireproof mask equipped with an infrared imaging system, which is composed of an infrared imaging system and a fireproof mask. The infrared imaging system is composed of an infrared camera, a circuit board, and a power supply composed of an infrared lens and an uncooled infrared focal plane array. , display screen and magnifying eyepiece, the uncooled infrared focal plane array is connected to the corresponding port of the infrared camera circuit; the display screen is placed on the incident side of the magnifying eyepiece to form an observer; the observation side of the magnifying eyepiece is placed on the observable side of the human eye position; the display screen is connected to the corresponding port of the observer circuit board; the corresponding port of the infrared camera circuit board is connected to the corresponding port of the observer circuit board; The system and the fire mask form a whole to achieve waterproof, fireproof, dustproof and shockproof. The infrared fireproof mask of the present invention has high space integration, compact and firm structure, the viewer is close to the human eye, the field of view is large, the parallax is small, the target is clear, the hands are free, the line of sight is not blocked, and it is convenient for walking and operation.

Description

technical field [0001] The invention relates to a fireproof mask, in particular to a fireproof mask which integrates an infrared imaging system and the mask. Background technique [0002] In recent years, infrared imaging systems have become extremely important equipment in firefighting and rescue work. It can obtain images of surrounding scenery in dark environments, allowing firefighters to identify paths, see people and objects to be rescued, and facilitate rescue. Fires are always accompanied by a lot of smoke, and infrared radiation can be imaged through the smoke, which is not a characteristic of other types of equipment. Infrared images are thermal images, which can display the temperature distribution and temperature difference of the scene, and some infrared imaging systems also have the function of temperature measurement. According to the heat distribution, firefighters can judge dangerous situations, and even find high-temperature sources without open flames, an...

Problems solved by technology

But it also brings a series of disadvantages, mainly: the infrared imager is installed on the helmet, which is relatively high from the head, and it is easy to touch other objects during firefighting operations, which will damage the instrument; the distance between the infrared imager and the human eye is large, resulting in greater Large parallax; limited by the size of the helmet, its power supply often needs to be installed elsewhere, not an integrated structure; the infrared imager, the observer and the power supply must be connected by wires, and the fire resistance of the wires is difficult to guarantee and is easy to break , and it is inconvenient to install and disassemble; the observer is outside the mask, and the distance from the human eyes is far away, so the field of view is small and the image is not clear
