Fully Electronic Interlocking System

Background

Railways and urban rail transit develop rapidly; while traditional interlocking systems, characterized by numerous interfaces, low integration, and insufficient automation and intelligence, struggle to meet modern transportationdemands. The emergence of the fully electronic interlocking system aims to address these challenges by enabling the electrification, modularization, and high integration of signal control, thereby enhancing system performance and efficiency.

The system complies with international standards including IEC 62280 to ensure global compatibility; and complies with domestic standards including TB/T 3027-2015 to guarantee compliance within China’s railway and urban rail transit sectors.

Product Features

High Integration and Miniaturization:
The fully electronic interlocking system enables the electrification and modularization of signal control equipment and is easier for installation and maintenance by reducing interfaces between devices and improving system integration and compactness.
High Safety and Reliability:
The system features all-weather real-time monitoring, fault self-diagnosis, and recovery capabilities. With multiple redundancy designs, it ensures high safety and reliability even under extreme conditions.
Flexibility and Scalability
The system supports flexible configuration and expansion, allowing customized design based on the specific requirements of different railway lines. It is wellpositioned to meet the evolving needs of future transportation systems.
Integrated Control of Interlocking and Platform Doors
Integrated with platform doors, the system reduces train-to-ground transmission nodes and potential failure points. This lowers construction costs and shortens project cycles, minimizes equipment room space, and enhances coordination efficiency.Meanwhile, it improves the safety and availability of the platform door control system.

Application Examples

Chengdu Metro Line 27: As the second fully automated metro line in Chengdu, Line 27 leads the new trend of smart mobility with its advanced technology applications. By replacing traditional relay combination cabinets,the fully electronic interlocking systemsignificantly reduces equipment footprint and wiring complexity, and supports hot-swapping of fault boards, increasing maintenance efficiency by 30%.

Nationwide Deployment: The fully electronic interlocking system has been deployed across 21lines nationwide.
