Centralized Vehicle Door Control for Platform Screen Doors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current door control systems for passenger transport vehicles are complex and require multiple central control units, leading to increased components and potential failure points, making them less reliable and more difficult to coordinate the opening and closing of vehicle and platform doors.
Innovation Solution
A centralized door control unit on the vehicle controls both vehicle and platform doors through permanent and temporary communication links, eliminating the need for a separate platform control unit and reducing components, with actuators only moving under direct control commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate central control units are provided for vehicle doors and platform doors, then each door system can be controlled independently, but the system complexity increases and reliability decreases due to more components and coordination requirements
Solution Approach 1:
The patent merges the vehicle door control unit and platform door control unit into a single integrated control unit located on the vehicle. This control unit executes door control programs that manage both vehicle doors and platform doors, eliminating the need for a separate platform-side control unit and reducing overall system complexity while maintaining independent control capability
2Ease of operation
If separate central control units are provided for vehicle doors and platform doors, then each door system can be controlled independently, but the reliability decreases due to increased potential failure points
Solution Approach 1:
By consolidating control functions into a single vehicle-mounted control unit, the patent reduces the number of independent control components in the system. This merger eliminates potential failure points associated with separate control units and their interconnections, thereby improving overall system reliability while maintaining the capability to independently control vehicle and platform doors
3Adaptability or versatility
If a separate platform control unit is provided, then platform door control can be autonomous, but the coordination between vehicle and platform doors becomes more difficult
Solution Approach 1:
The patent combines the control functions for both vehicle doors and platform doors within a single control unit on the vehicle. This unified control architecture simplifies coordination by having one control entity manage both door systems, eliminating the complexity of inter-unit communication and coordination protocols that would be required if separate control units were used

AI summary
The invention relates to a door control system comprising a vehicle (10) for passenger transport, in particular a rail vehicle, with at least one vehicle door (11;12;13) and a platform (20) with an access control device (30), wherein the access control device (30) has at least one platform door (31;32;33), and each vehicle door (11;12;13) is assigned a vehicle door actuator (51;52;53) with means for moving the respective vehicle door (11;12;13) and each platform door (31;32;33) is assigned a platform door actuator (41;42;43) with means for moving the respective platform door (31;32;33). A central door control unit (50) of the vehicle is designed to control both the at least one vehicle door actuator (51;52;53) and the at least one platform door actuator (41;42;43).A first communication link (60) exists between the central door control unit (50) and the at least one vehicle door actuator (51; 52; 53), via which control commands for the movement of a vehicle door (11; 12; 13) can be transmitted to the respective vehicle door actuator (51; 52; 53). For controlling the at least one platform screen door actuator (41; 42; 43), a temporary second communication link (40; 61) is established between the central door control unit (50) and the at least one platform screen door actuator (41; 42; 43), via which control commands for the movement of a platform screen door (31; 32; 33) can be transmitted from the central door control unit (50) to the respective platform screen door actuator (41; 42; 43). The invention further relates to a method for the joint control of vehicle doors (11;12;13) and platform screen doors (31;32;33) via a central door control (50) of the vehicle (10).
