Door operating system for passenger coaches taking safety into consideration

摘要

An intelligent pneumatic door operating system for passenger trains is developed taking fail-safe operation into account, equipped with interface function to train information system. Being designed as small size and lightweight with built-in CPU, this system is distributed to each door, which controls electro-magnetic valves for door operation and weakening of door operating force. Input and output circuits of the door control system are designed as the safety operation despite of the compact size.
