Description

Technical Field

[0001] This utility model belongs to the field of fire helmet technology, and in particular relates to a precise positioning intelligent safety helmet for fire fighting. Background Technology

[0002] Fire helmets are essential protective equipment for firefighters during rescue operations at fire scenes. They provide head protection against falling objects, sharp objects, and other hazards. However, as core protective gear, fire helmets primarily focus on passive protection and lack the ability to actively monitor the firefighter's vital signs and the fire environment.

[0003] First, existing fire helmets cannot monitor a firefighter's physical condition in real time, failing to detect dangerous situations such as oxygen deficiency, which could endanger their lives. Second, existing fire helmets cannot detect the presence of toxic gases in the environment. Statistics from the US National Fire Protection Agency (NFPA) show that approximately 60% of firefighter injuries and fatalities are directly related to toxic gas inhalation, with 30% of these cases due to the failure to detect gas leaks in time. Therefore, developing intelligent fire helmets with vital sign monitoring and environmental detection capabilities is of great significance for improving the safety and efficiency of fire rescue operations.
