Rail yard train-switching system, control device, and control method
A rail yard train-switching system includes train-moving machines and a control device. The train-moving machines each draw one of railroad trains in a rail yard. The control device transmits a traction command to the train-moving machines based on an operation schedule. The train-moving machines each move, based on the traction command transmitted from the control device, to a first location specified by the traction command to couple with an appropriate one of the railroad trains, and draw the one of the railroad trains from the first location to a second location specified by the traction command.
1 . A rail yard train-switching system comprising:
a plurality of train-moving machines to draw a railroad train in a rail yard; and
a controller comprising a processor and a memory and configured to select a train-moving machine of the plurality of train-moving machines to perform a switching operation based on states of the plurality of train-moving machines and to transmit a traction command to the selected train-moving machine based on an operation schedule of the switching operation including a start time for the traction command, wherein
the selected train-moving machine
moves, based on the traction command transmitted from the controller, to a first location specified by the traction command to couple with the railroad train, and draws the railroad train from the first location to a second location specified by the traction command, wherein
the selected train-moving machine
includes a target detection circuitry to detect an intrusion to be detected into the rail yard,
the controller
transmits a patrol command to the selected train-moving machine based on a preconfigured patrol schedule, and
the selected train-moving machine
patrols the rail yard while detecting presence or absence of the intrusion to be detected using the target detection circuitry, based on the patrol command transmitted from the controller.
2 . The rail yard train-switching system according to claim 1 , wherein
the controller includes
a route determination circuitry to determine a first travel route to the first location of the selected train-moving machine, and a second travel route from the first location to the second location of the selected train-moving machine, and
a route establishment circuitry to cause a coordinator device to control a switch in the rail yard, based on the first travel route and on the second travel route determined by the route determination circuitry.
3 . The rail yard train-switching system according to claim 2 , wherein
the controller
transmits an entry prohibition command prohibiting ones of the plurality of the train-moving machines other than the selected train-moving machine that receives the traction command, among the plurality of the train-moving machines, from entering the first travel route and the second travel route.
4 . The rail yard train-switching system according to claim 1 , wherein
the plurality of train-moving machines
move, based on the traction command, in conjunction with each other a railroad train specified by the traction command.
5 . The rail yard train-switching system according to claim 1 , wherein
the selected train-moving machine
includes a sensor for inspecting the railroad train, and
the controller or the selected train-moving machine
inspects the railroad train based on a result of detection performed by the sensor.
6 . The rail yard train-switching system according to claim 5 , wherein
the sensor
is an image sensor, and
the controller or the selected train-moving machine
compares an image of the railroad train captured by the image sensor with an image of the railroad train in a normal condition to detect an anomaly of the railroad train.
