ATC System

Small in size
The signal decision component and the control component have been converted to support full digital processing and unified to produce smaller dimensions (reduced 50 percent compared to our conventional units). The unit supports a wide range of signal systems including the AM modulation system and MSK modulation system.

Enhanced reliability
While maintaining the time-proven dual computer system for better fail-safe characteristics, the unit has its signal decision component and its controlling component converted to support full digital processing, and unified to dramatically reduce the number of parts and wiring and to improve reliability.

Improvement for maintenance saving
The configuration with DSP digital circuits for the processes from detection to signal determination has eliminated the need to make adjustments to the operation level.
The introduction of a test record component for automatic testing curtails the testing period. Its advanced operation record function enables easier failure analyses.

Enriched control functions
The introduction of low-power braking control and overrun stop control to the onboard pattern system has raised the comfort in the ride and the scheduled speed.

ATO System

Shortened time of actual operation coordination
A dynamic "simulated operation test" run in the factory shortens the duration of actual train operation.

Minute operation control
A comprehensive determination based on the wealth of knowledge accumulated from the experience of skilled drivers on rail conditions, car characteristics and other aspects produces finely detailed train control.

Flexible response to changes in operating status
The inference of coordination required based on data on control status and operation state allows a flexible response to changing conditions.

Data expression in data format for easy knowledge accumulation and alteration
Since control knowledge is expressed in data format, it is easy to apply empirical and other rules and to edit and add to it.

Simplified predictive control
The prediction of indications at the forward signal with the recognition of the running zone and changes in ATC signals ensures that the train operates in the optimal operation pattern.(Introduction of digital ATC enables more minute prediction.)

On-schedule operation
Automatic judgment from operational delays changes operating patterns to shorten the driving time.
