Description of the Related Art Conventionally, various guidance broadcasts using wireless microphones have been carried out in order to ensure the safety of passengers at platforms such as when entering / exiting trains and opening / closing doors at station platforms. When the door is opened and closed, a door closing signal, a door closing confirmation signal, a restart door signal, an emergency stop signal, and the like are provided with a predetermined display pattern and display color on a door closing signal indicator suspended from the ceiling of the home. A closing signal is displayed, and the conductor confirms this.
Stop operation is being performed.

In the above conventional method, when the platform is crowded with passengers, such as during a rush hour in the morning and evening, or in a station platform where the platform itself is curved, a door closing operation fixedly installed on a pillar of the platform is performed. There is also a problem that safety may not be ensured sufficiently, because a boarding or emergency may occur immediately after the operation of the container. However, in order to solve this problem, Japanese Patent Application Laid-Open No.
In Japanese Patent No. 67057, a wireless microphone function and a control function of a door closing signal indicator for instructing opening and closing of a door are controlled by a wireless device using a different transmission method and frequency, respectively, by a door opening / closing operation and a train departure / train from an arbitrary place. A door closing operation device capable of performing a stop operation is presented.
