TSRS Automatic Speed Restriction Command Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing railway vehicle speed restriction technologies, particularly in China Train Control System-2 (CTCS-2) and CTCS-3, face issues with manual management leading to accidents and inconsistent speed restriction enforcement, as decentralized control systems lack automation and attendant involvement, leading to potential omission of speed restrictions.
Innovation Solution
A centralized Temporary Speed Restriction Server (TSRS) is introduced to automatically split and distribute temporary speed restriction commands to Train Control Centers (TCC) and Radio Block Centers (RBC) based on defined zones, ensuring consistent speed restriction enforcement across CTCS-2 and CTCS-3 systems without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If decentralized control is used for speed restriction management, then operational flexibility is improved, but consistency of speed restriction enforcement deteriorates
Solution Approach 1:
The patent introduces a Temporary Speed Restriction Server (TSRS) as an intermediary component between the dispatching system and the distributed TCC/RBC systems. The TSRS receives speed restriction commands from the dispatching system, automatically splits them according to jurisdiction boundaries, and distributes them to appropriate TCC and/or RBC systems. This intermediary mechanism ensures that all distributed systems receive consistent and complete speed restriction information while maintaining operational flexibility.
2Device complexity
If manual management mode is used for speed restriction, then device complexity is reduced, but reliability of speed restriction enforcement deteriorates
Solution Approach 1:
The patent implements an automated system where the TSRS performs self-service functions by automatically receiving speed restriction commands from the dispatching system, autonomously splitting the commands according to pre-configured jurisdiction boundaries of TCC and RBC systems, and automatically distributing them to the appropriate systems without requiring manual intervention from station attendants. This automation eliminates human error while maintaining manageable system complexity through standardized processes.
3Reliability
If automated centralized distribution is implemented, then consistency of speed restriction enforcement is improved, but device complexity increases
Solution Approach 1:
The patent segments the speed restriction management function by introducing a dedicated TSRS component that handles the complex task of command splitting and distribution. The TSRS divides the overall speed restriction command into smaller sub-commands tailored to each TCC and RBC jurisdiction, allowing the complex automated distribution logic to be isolated in a single component rather than distributed across multiple systems. This segmentation improves consistency while containing the increase in device complexity to a specific modular component.

AI summary
The present invention provides a method and a device for sending temporary speed restriction command in C3 system. The method comprises: a TSRS receives a temporary speed restriction command issued by a CTC; the TSRS, according to the speed restriction zone starting point, the speed restriction zone end point, and the jurisdiction of each speed restriction of each TCC and/or RBC on the railway line corresponding to the line number, automatically splits, and then sends a corresponding temporary speed restriction command to the related TCC and/or RBC, and the TCC sends the C2 speed restriction information to a C2 onboard device via an active transponder, and the RBC sends the C3 speed restriction information via a GSM-R. Through setting a TSRS in a railway system and connecting the TSRS to the CTC to obtain a temporary speed restriction command, and distribute the temporary speed restriction command to related TCC, RBC, so as to realize automatic distribution of each TCC, RBC and a centralized management train control speed restriction command within a full-line management and control range; through the TSRS, C2 and C3 speed restriction commands can be set and cancelled simultaneously, so as to guarantee consistency of two train control modes.
