Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a train door safety confirmation system for assisting safety confirmation of a door so that the train can be started after the train door is surely closed.

[0002]

2. Description of the Related Art Conventionally, safety confirmation when a train stopped at a platform closes the door in order to depart, the confirmation by the detection result of a door opening / closing sensor attached to the door and the station staff at the platform Both the visual inspection of the door and the visual confirmation in front of the door of the surveillance camera installed on the platform are used together.

In the current state of door open / close detection by the door open / close sensor, it is considered that the door is closed in terms of signal processing even when the actual door is closed with a slight gap left. If this is set so that it is determined that the door is closed due to signal processing only when the door is completely closed, for example, when the hem of the clothing of the passenger who boarded the train last is slightly sandwiched between the doors Even if there is no problem, it will be considered as opening the door for signal processing,
This is because the train cannot be departed as it is, and this will hinder the scheduled operation of the train, especially during rush hours.

On the other hand, if it is judged that the door is closed due to signal processing even if there is a slight gap in the door in reality, and the train departure is OK, a part of the clothes left by the person on the platform side is caught in the train door. There is a danger that the train may leave in the state of being left unattended.

Therefore, crew members and station staff visually confirm between the platform and the train to see if there is no problem in leaving the train as it is when the door is slightly open. The condition between the platform and the train is photographed and displayed on a monitor TV to check and judge.

[0006]

However, in such a conventional train door safety confirmation method, regardless of the detection result of the door opening / closing sensor, all the train doors are comprehensively monitored for safety confirmation. Since we do so, it is not possible to check with the crew alone, especially in platforms with poor visibility, so multiple station staff must always make safety confirmation on the platform side to notify the crew and let them start, so many personnel are required. It is necessary and has been a factor that has hindered the reduction in the number of passengers and station staff in recent years and the unmanned operation.

[0007] In addition, there is a tendency that the number of homes with poor visibility tends to increase due to the necessity of constructing curved homes due to the lengthening of train formations due to the increase in transportation demand in recent years and due to land shortages. The number of personnel must be increased, and the development of a train door safety confirmation system that enables efficient safety confirmation is required.

The present invention has been made in view of the above-mentioned conventional problems. A door which is not completely closed is specified, a situation near the door is photographed by a surveillance camera, and a fixed image in the train is fixed. A train door safety confirmation that can be displayed on a monitor TV installed at a certain position or a fixed position on the platform so that safety confirmation can be done, so that only the crew or only one station staff can surely confirm the safety and prepare for train departure The purpose is to provide a system.
