Description

[Technical Field]

[0001] The present invention relates to the field of fire detection, and more particularly to an intelligent fire detection device. [Background technology]

[0002] Fires are characterized by their suddenness, rapid spread, and tendency to produce toxic smoke, which can result in casualties and serious property damage. Common causes include electrical circuit failures (30%-40%), improper fire management, spontaneous ignition, lightning strikes, and other natural factors. Each type of fire can pose a threat to the safety of people's lives and property, so it is important to carry out thorough firefighting activities.

[0003] Among many fire situations, fires occurring inside buildings are extremely inconvenient for rescue due to the complex structure of the building, and if firefighters rush into the scene directly without knowing the fire situation inside, it will delay the rescue mission and put the firefighters themselves in danger, so a detection device that can intelligently detect the source of fire is needed instead of firefighters having to enter the danger zone to reveal the fire situation.In addition, due to the urgency of the firefighting mission, rescue equipment needs to be easy to carry so that firefighters can arrive quickly with the equipment, so an intelligent fire detection device is proposed.
