Indigenous design and development of Obstacle Deflection and Derailment Detection device (ODD)

Background:

Functional Requirement-

• ODD shall detect obstacles of specific condition on the track.
• ODD shall remove small obstacles from track.
• In the case of derailment of Train, ODD shall detect the derailment.
• ODD shall provide distinct signal to TCMS for obstacle and derailment detection.

Challenge:

• Using link structure, rectangle-shaped rotating pivot will pass sensing area of non-contact detecting sensors by rotating of detection bar.
• Non-contact detecting sensors installed in the detecting sensor box will be activated by sensing movement of the pivot.
• ODD system is working on mechanical principle. Using SIL level 2 certified fail-safe inductive sensor, reliability of system has to be ensured and system failure by malfunction of sensors is excluded.
• Detection bar shall be V-shaped to remove the obstacles to the outside of track.

Future Expectation from the prototype / Technology developed

The existing and upcoming UTO (Driverless trains) projects are seeking ODD as a mandatory requirement. With BEML experience and capabilities, it is proposed to take up design and development of Obstacle deflection and derailment detection device as a R&D project.
