AI Technical Summary

Technical Problem

Current door devices in rail vehicles have high complexity in cabling and signal processing due to centralized control systems, leading to increased sensitivity to interference and higher demands on data transmission.

Method used

A decentralized control system is implemented, where a first door control is located outside the door leaf and a second door control is integrated into the door leaf, allowing local intelligence for actuation and control, reducing the need for continuous signal transmission between components and central control.

Benefits of technology

This approach reduces the complexity of cabling and data transmission, decreases interference sensitivity, and allows for more efficient and reliable door operation by distributing control logic, enabling independent operation of door leaf components.

Abstract

The invention relates to a door device (200) of a rail vehicle (300), at least comprising: a door frame with a door opening, at least one door leaf (5a, 5b), which is driven relative to the door frame by a door leaf drive (1a, 1b), for opening and closing the door opening, a first door controller (10) which provides a first set of functions of a door leaf operating or door leaf actuating control of the at least one door leaf (5a, 5b) and which is arranged outside of the at least one door leaf (5a, 5b), in particular on the door frame. The invention is characterized by a second door controller (56) which is arranged on or in the at least one door leaf (5a, 5b) and which provides a second set of functions of the door leaf operating or door leaf actuating control of the at least one door leaf (5a, 5b).
