The Tokyo Metropolitan Bureau of Transportation announced that it will introduce a platform door opening / closing control system using a QR code (tQR) at all stations on the Asakusa Line by 2023.
The tQR was jointly developed by the Tokyo Metropolitan Bureau of Transportation and Denso Wave. It is a mechanism that reads the tQR with a camera (reading device) installed on the ceiling of the platform and opens and closes the platform door according to the opening and closing of the vehicle door.
Information on the position of the doors and the number of trains is stored in tQR, and even if the number of doors per car and the number of trains are different, the platform doors can be controlled, so there is no need to repair the cars. ..
The Tokyo Metropolitan Bureau of Transportation has already introduced this system at four stations on the Asakusa line, Shimbashi station, Daimon station, Mita station, and Sengakuji station, and is proceeding with the development of the remaining 15 stations on the Asakusa line, and by 2023 The policy is to introduce it at all stations on the Asakusa line.
Platform doors that use the same mechanism have been put to practical use on the Keihin Electric Express Railway and the Kobe Municipal Subway, and there are widespread movements toward full-scale introduction, such as the start of demonstration tests at JR Central.
