摘要： A switch locking system and method of an authorized locomotive for safely traversing a switch in a railway including sending a lock command from a computer onboard the authorized locomotive to a switch controller associated with the switch; determining if a lock confirmation from the switch controller is received by the computer onboard the authorized locomotive; and safely traversing the switch upon receipt of the lock confirmation. The switch locking system and method may include sending an unlock command from a computer onboard the authorized locomotive to a switch controller after the train clears the switch.

摘要： The present invention relates to a switch monitoring method and a switch monitoring system, a railway line management method and a railway line management system. Electric signal of a switch motor during pulling of the switch can effectively reflect status of the switch, when the switch is in a stable state, electric signal of its motor is very steady during pulling of the switch; however, when the switch is in an unstable state, there will be different degrees of fluctuation in electric signal of its motor during pulling of the switch. Thus, the invention may be used to identify state of a switch by monitoring electric signal of a switch motor, and further take different measures based on different states of the switch. With these measures, accidents due to switch failure may be effectively reduced, and train delay time may also be reduced through proper line management.
