Ensuring safe operation of the high-speed EMU

Technical solutions built using software-and-hardware complexes to integrate the high-speed EMU into infrastructure containing a modern interval-regulation system that addresses tasks of increasing line capacity and train speeds while maintaining the same level of functional safety integrity.

Ensuring safe EMU movement on the first HSR line Moscow – Saint Petersburg and on other tracks of the Russian Railways network open to general use

1. Prevention of accident and pre-accident situations in movement by advance warning of the driver using visual and audible signalling, and by forced braking and stopping of the EMU.

2. The safety assurance system provides:

• operation in centralised mode (with RBC data) and local mode (with ALS data) of train movement control;
• operation at train speeds up to 400 km/h;
• operation with RBC over a protected duplicated radio channel;
• entry of locomotive and train characteristics and their storage in non-volatile memory;
• operation in train and shunting modes, in multiple-unit mode (multiple-unit operation).

3. Basic functions:

• permissible speed control;
• driver vigilance control;
• parameter recording;
• interval regulation.

1. Satellite technologies. Electronic map of sections and positioning by railway coordinates.

2. Cryptographic protection. Protection of the radio channel using certified means.

3. Interval regulation. A set of technologies that increase line capacity, including cab-signalling technologies and technologies using transmission of safety-critical information over a digital radio channel.

4. Modularity. Capability for flexible expansion of system functionality.

5. Extended diagnostics. Full recording of system information exchange for analysis. Use of predictive diagnostic methods for condition of the system's own nodes and external modules.

6. Data exchange. Connection to data transmission networks built on various technologies and principles, including but not limited to: CAN;

Ethernet.

7. Software is developed using:

• programming languages: C, C++;
• development tools: Visual Studio, Eclipse, NetBeans, and specialised integrated environments for embedded microcontroller software (IAR, Keil, CubeIDE);
• source code management tools: SVN, Git;
• requirements management tools: T-FLEX RM.
