System for controlling movement of passenger train

Abstract

A system for controlling movement of a passenger train having a locomotive and a plurality of doors is provided. The system includes a door status sensor to determine open and closed status of each door of the locomotive. The system further includes a first control module coupled to the door status sensor and a relay coil through a first diode. The relay coil is energized on receipt of input from the door status sensor, when all doors of the locomotive are closed, and the energized relay coil allows controlling movement of the locomotive. The system further includes a door override switch. In an actuated condition, the door override switch allows power to flow from a power source to the relay coil, thereby energizing the relay coil. The energized relay coil allows controlling movement of the locomotive.

Description

TECHNICAL FIELD[0001]The present disclosure relates to a passenger train and more particularly to a system for controlling movement of the passenger train.BACKGROUND[0002]With the development of technology, manually and mechanically operated doors of a passenger train are being replaced with electrically and automatically operated doors. As such, operation of the doors of the passenger train needs to be monitored to achieve safety requirements during movement of the passenger train. For example, open condition of the doors during movement of the passenger train may not be safe to the passengers. Accordingly, the doors of the passenger train need to be maintained in a closed condition during movement of the passenger train.[0003]Korean Patent Number 101252542B1, hereinafter referred to as the '542 patent, describes a door control circuit for a train that includes a molded case circuit breaker, a rear train contact relay, a front train contact relay, a door switching switch, a door sw...

AI Technical Summary

Benefits of technology

The present invention relates to a system for controlling the movement of a passenger train. The system includes sensors on each door of the train that detect whether the door is open or closed, and a control module that receives information from the sensors. The control module communicates with an operator of the train to control its movement based on the status of the doors. The system also includes a relay coil and a door override switch for selectively controlling the movement of the train. The technical effect of the invention is to improve safety and reliability by automatically controlling the movement of the train based on the status of its doors.

Problems solved by technology

For example, open condition of the doors during movement of the passenger train may not be safe to the passengers.

As such, '542 patent involves two individual feedback loops, thereby rendering the door control circuit complex.

In addition, such independent circuits add to the cost of the door control circuit.
