In the case of large fires, it is often the case that an accident occurs in which the disaster relief personnel are isolated due to the collapse of the building in which the fire occurred, or the collapse of the disaster relief crew.

The accident of the disaster rescue crew is one cause of failure to relieve the disaster rescue crew at the appropriate time because the position of the disaster rescue crew who entered the fire site can not be grasped accurately by the command and control headquarters (fire command car, etc.) Another reason is that the absence of data on disaster relief crews and evolving sites does not allow the Command & Control Headquarters to recognize and warn of the danger signs in advance.

In recent years, in order to prevent these disaster relief crew accidents, sensing devices for tracking the position of disaster relief crews at the fire site and for checking the status of disaster relief crews are being developed. Through the information transmitted from such equipment, Research on the command system that can support efficiently has been continued.
