Generally, regular / irregular repair / reinforcement is frequently performed in a railway / road / airport / subway. At this time, it is necessary to evacuate to the safety zone avoiding the moving means approaching through the continuous front sight. The same applies to facilities that are mainly used for forward surveillance, iron-frame boundaries, and operations during operations.

Although the monitoring status is monitored by arranging the monitoring personnel during the work, the supervisor is also often working for a long time, and the state boundary is loosened, leading to the accident due to the monitoring failure. In the event of an accident, firstly, human accidents and facilities accidents are caused, and second, the public use of the public facilities is inconvenienced.

Thus, there is a need for a monitoring system that is free from monitoring failure due to fatigue without loosening the boundaries of the human monitoring system.

The conventional method is mainly used for monitoring the entrance of a train by a fixed signal lighting method, but it is difficult to apply it to a place where the working position is flexible. In addition, there has been a problem that errors are caused in a state of influencing the sensing condition due to heavy rain or heavy snow.
