Various efforts have been made to prevent safety accidents, but safety accidents are constantly occurring in industrial sites for various reasons and reasons, regardless of the object of work.

Especially, in a working environment like a power plant, even with a small mistake, it can be said that extreme safety is required because a huge problem such as interruption of local power supply, downsizing of the entire power plant and damage to human life can be spread.

In the case of coal-fired thermal power plants, various tasks are being performed in a wide range of areas such as coal field, conveying by belt, dropping, crushing, steam generation, and energy generation using turbines. Welding work, etc.) frequently occur, so prevention and management of safety accidents such as fire is more important.

Although various tasks that use firearms for safety accident prevention, job monitoring and control are subject to complex steps such as planning, task execution, and task completion, most of these methods are performed by workers, supervisors, etc. It is inherently a human-dependent method, such as a manual method or a method of visual confirmation, so that there is always the possibility that an accident may occur.

In addition, it is often the case that firearm operations to be supervised and supervised are not actually performed based on the planned contents, or workers voluntarily perform them without prior permission or without supervision by supervisors or supervisors. In addition, even if a safety accident such as an actual fire occurs, it is difficult to immediately recognize a safety accident as well as immediate follow-up action.
