Description

Technical Field

[0001] The present invention belongs to the technical field of fire helmets, and particularly relates to a precision positioning intelligent fire safety helmet. Background Art

[0002] A fire helmet is one of the important protective equipments for firefighters during rescue work at the fire scene. It can provide protection for the heads of firefighters and prevent them from being injured by falling objects, sharp objects, etc. As the core protective equipment for firefighters, the functions of the fire helmet mainly focus on passive protection and lack the ability to actively perceive the life status of firefighters and the fire scene environment.

[0003] First, the existing fire helmets cannot understand the physical condition of firefighters in real time and cannot detect in time whether dangerous situations such as hypoxia occur to firefighters, which may endanger the lives of firefighters; second, the existing fire helmets cannot detect whether there are toxic gases in the on-site environment. Statistics from the US NFPA show that about 60% of firefighter casualties are directly related to inhaling toxic gases, and 30% of them are due to the failure to detect gas leakage in time. Therefore, the research and development of intelligent fire helmets with vital sign monitoring and environmental detection functions is of great significance for improving the safety and efficiency of fire rescue.
