Abstract
There is disclosed a vehicle train control apparatus and method for controlling the operation of a vehicle train by a second control equipment provided in a different control vehicle of the train in the event of the failure of the train control equipment of a first control vehicle initially selected to control the train.
Claims16
In control apparatus for a train of vehicles operative with a roadway track and having at least a primary control vehicle and a secondary control vehicle, with each control vehicle including an automatic train control equipment, the combination of
- first means provided in said primary control vehicle for receiving a control signal from the roadway track,
- second means provided in each of said primary and secondary control vehicles, with the second means in said primary control vehicle being coupled with the first means in the primary control vehicle and providing an interface control connection between said primary control vehicle and said secondary control vehicle,
- third means provided in each of the primary control vehicle and the secondary control vehicle, with the third means in the primary control vehicle being coupled with the second means in the primary control vehicle for selecting either a normal operation with the primary control vehicle controlling the train or a handback operation with the secondary control vehicle controlling the train,
- with said second means including first signal means in each of the primary and secondary control vehicles and being energized in the primary vehicle for determining the secondary control vehicle to control the train for said handback operation, and with said second means including second signal means in each of the primary and secondary control vehicles and being energized in each of the primary and secondary control vehicles for enabling the secondary control vehicle to control the train for said handback operation.
In control apparatus for a train operating along a roadway track providing a control signal and having a first vehicle with a train control equipment and a second vehicle with a train control equipment, the combination of
- first means provided in each of said first and second vehicles and establishing a control connection between the first vehicle control equipment and the second vehicle control equipment,
- second means provided in each of said first and second vehicles and operative with the first means of the first vehicle for selecting either a normal train control operation with the first vehicle control equipment determining the operation of the train or a handback train control operation with the second vehicle control equipment determining the operation of the train,
- with said first means including first signal means in said first vehicle for establishing said control connection associated with said first vehicle and including second signal means provided in each of the first vehicle and the second vehicle and coupled with the first signal means in the first vehicle, with said first signal means in the first vehicle energizing said second signal means in each of the first and second vehicles for establishing said control connection associated with each of the first vehicle and the second vehicle.
In the method of controlling a train of vehicles operative with a roadway track providing a control signal with said train having at least a front control vehicle and a rear control vehicle that each have a train control equipment,
- the steps of
- sensing the control signal associated with the front control vehicle for determining the operation of the train along said roadway track,
- controlling said train with the train control equipment of a primary control vehicle in response to said control signal for a normal control operation of said train,
- controlling said train with the train control equipment of a secondary control vehicle in response to said control signal for a handback control operation of said train,
- providing a first signal circuit in the primary control vehicle for establishing said handback control operation of the train, and
- providing a handback signal circuit in each of the primary control vehicle and the secondary control vehicle for enabling said handback control operation of said train.
