Description

Technical Field

[0001] The present invention relates to an indoor space welding and fire identification system, and more particularly to an indoor space welding and fire identification system, which detects the real-time working status by detecting the location where welding work is performed to prevent possible fires from occurring when welding work is performed in the indoor space, and determines whether there is a fire by detecting and identifying sparks generated by welding and fire. Background Art

[0002] Generally speaking, buildings are equipped with smoke detectors to sound an alarm when a fire occurs in order to reduce damage to property or people.

[0003] These fire detection devices include heat detectors that detect heat when a fire occurs, smoke detectors that detect smoke, and water sprinklers (also known as sprinklers, hereinafter referred to as "sprinklers") that spray water when a fire occurs.

[0004] Traditional fire detection and extinguishing systems typically use differential thermal detectors and constant-temperature thermal detectors. Differential thermal detectors, in particular, detect the expansion rate of the air inside. At room temperature, the air expansion rate is constant due to temperature changes at a fixed rate. However, when a fire breaks out, the sudden change in temperature causes the air to expand rapidly. Detecting the fire by detecting this change in the air expansion rate results in a slow response to fire. Furthermore, since these systems cannot operate until the fire has grown to a certain size, early fire extinguishing is not possible.

[0005] To prevent various hazards (such as fire, explosion, and asphyxiation) in industrial sites, various sensors are typically deployed in the workplace to monitor hazards in an integrated manner. For example, in the case of a fire, flame or lighting detection is used; in the case of asphyxiation, gas and oxygen concentration detection is used to identify hazards.

[0006] However, in industrial sites involving welding, it is difficult to distinguish sparks from those from fires, which can lead to welding being misidentified as a fire even when it is in progress. This can cause danger or evacuation warnings to be issued even in non-disaster situations, causing confusion among workers, leading to unnecessary evacuations and reduced work efficiency.
