AI Technical Summary

Technical Problem

Existing train determination systems fail to accurately identify trains that do not require the opening of platform doors, posing a safety risk when such trains arrive at platforms.

Method used

A train determination system using an image acquisition unit, character detection unit, and determination unit, employing a pre-trained learning model via machine learning to identify specific train operation types from destination indicators, controlling platform door opening and closing based on character detection and position analysis.

Benefits of technology

Accurately determines trains that do not require platform door opening, ensuring safe operations by controlling door opening and closing operations without delay, facilitating a simple, ground-based platform door system.

Abstract

The system accurately identifies train types that do not require the opening of platform screen doors. [Solution] The train determination system 1 comprises an image acquisition unit 11, a character detection unit 12, a determination unit 13, and a signal output unit 17. The image acquisition unit 11 acquires an image of the side or front of the train, including the destination indicator. The character detection unit 12 uses a learning model created in advance by machine learning using sample data related to a predetermined string of characters displayed on the destination indicator to detect each character in the string of characters displayed on the destination indicator in the image. The determination unit 13 determines whether the detected string of characters matches a predetermined string of characters. The signal output unit 17 outputs a signal S1 indicating the determination result by the determination unit 13 to a control panel 2 that controls the opening and closing operation of the platform doors 3 installed on the platform. The predetermined string of characters is a string of characters that represents a type of train operation that does not require the opening operation of the platform doors 3.
