Description

A helmet-mounted infrared detection and image transmission processing system

technical field

The invention belongs to the technical field of infrared detection, and in particular relates to an infrared detection and image transmission processing system.

Background technique

Under the current communication conditions, when a fire breaks out, the commanders in the back field judge the fire situation and make operational decisions mostly through the information sent back by the fire station signalers orally. There will be a large error in transmission. At this stage, the fire communication command system is the weakness of our country's fire brigade, and it is difficult for various advanced communication technologies and concepts to really enter the field of fire protection for practical application. Therefore, the communication command system for fire protection developed by advanced communication technology will have great market prospects and application space.

The infrared thermal imager uses the infrared detector and the optical imaging objective lens to receive the infrared radiation energy distribution pattern of the measured target and reflect it on the photosensitive element of the infrared detector to obtain an infrared thermal image, which is consistent with the thermal image on the surface of the object The distribution field corresponds. Generally speaking, the infrared thermal imager is to convert the invisible infrared energy emitted by the object into a visible thermal image. The different colors on the thermal image represent the different temperatures of the measured object. Due to factors such as small temperature field differences and complex on-site environment, a good thermal imager must have 320*240 pixels, a resolution of less than 0.1°C, a small spatial resolution, and the ability to synthesize infrared images and visible light images. Because infrared thermal imaging technology can perform non-contact, high-resolution temperature imaging, generate high-quality images, provide a lot of information on measurement targets, and make up for the lack of human eyes, it has been used in power systems, civil engineering, Automobile, metallurgy, petrochemical, medical and many other industries have been widely used, and the future development prospect is even more limitless.

Infrared thermal imaging cameras are widely used in fire fighting and rescue, rescue and disaster relief operations, and fire inspections by fire supervisors. In the fire fighting industry, thermal imaging cameras are divided into two categories: rescue type and detection type. Among them, the infrared camera of salvation is usually a handheld thermal imager, which requires battery power, and has the functions of infrared image display and rough temperature indication. It is required to be able to guide firefighters to rescue personnel, find fire sources, and prevent firefighters from straying into high-temperature dangerous areas under severe conditions of dense smoke and high-temperature fire scenes. It is an important fire-fighting and rescue equipment. From the point of view of use, handheld thermal imaging cameras for firefighting are not very convenient to carry, and must be operated by hand, which reduces the combat efficiency of firefighters to a certain extent because they cannot free their hands.
