Description

  The present invention relates to a train operation system and a ground-side operation device, and in particular, when a driver cannot control a train and a deadman device mounted on a train cab operates, a train on which a passenger is placed can be quickly and The present invention relates to a system for safely moving and resuming operation of a route at an early stage.

  In a conventional train operation system, an operator operates a master controller and a brake command device to operate a train safely according to instructions from an automatic train control (ATC) device and an automatic train operation (ATO) device. As shown in FIG. 1, in the ATC device, a block that is electrically divided for each length of the rail 10 on which the train 13 runs is formed, and the ground device sends out the speed information allowed for the train for each block. . A speed sensor 7 coupled to the train axle transmits a speed pulse in response to the rotation of the axle. The ATC control unit 4 which is an ATC on-board device outputs a brake command based on the output of the ATC antenna 5 and the speed pulse. The train 13 travels and stops by the drive control device 8 and the brake control device 9 (see Patent Document 1).

  The ATO device is a device for automatically driving the train 13 based on a command from the ATO ground device. The ATO device receives a departure command, departs the train, receives a deceleration command, and stops the train.

The master controller is equipped with a deadman device, and the driver is unable to operate for some reason (specifically, when the driver releases his / her hand from the handle of the master controller, The emergency brake is automatically activated when the engineer releases his / her foot from the pedal at the driver's seat.

  In the above-described conventional technology, there is no function of moving a stopped train after the operation of the deadman device, and there is a problem that it is difficult to quickly recover the normal route state after the train stops.

  The present invention relates to a vehicle upper side driving device that operates a train, a deadman device that detects that the driver cannot control the train and stops operation of the train by the vehicle upper side driving device, and the deadman device operates the train. Vehicle-side vehicle information transmission device that transmits a deadman device operation signal when stopped, a ground side driving device that remotely controls the train, and a ground side that receives the deadman device operation signal and transmits a driving device remote operation signal And a vehicle information transmission device, and a train operation system that operates a train in a normal operation mode by a driver's operation on the upper side driving device or an emergency operation mode by a remote operation signal from a ground side driving device.

  Moreover, this invention is a train operation system in which the said ground side operation apparatus becomes possible [operation | movement of a train in emergency operation mode], if the said deadman apparatus operation signal is received.

  In the present invention, the ground side driving device receives and displays an image of a train front view from the vehicle upper side information transmission device, receives an operation of an operator, and displays a driving signal of the train on the vehicle upper vehicle. It is a train operation system sent to an information transmission device.

  Furthermore, the present invention is the train operation system that switches from the normal operation mode to the emergency operation mode when the vehicle upper side operation device receives emergency command information from the ground side vehicle information transmission device.

  Further, the present invention receives a deadman device operation signal, receives and displays an image of a train front view from the vehicle upper side information transmission device, and receives an operation of an operator to display the train operation signal as the vehicle upper vehicle. This is a ground-side driving device that is sent to the information transmission device.

  According to the present invention, when the driver cannot control the train and the deadman device operates, the train is provided with a function to move the train to the nearest station or the target location by an operation from the ground side. It can be moved safely and promptly.

The best mode for carrying out the present invention will be described.
Hereinafter, embodiments of the train operation system and the ground side operation device of the present invention will be described with reference to the drawings.

  Examples will be described. The train operation system of the present embodiment is shown in FIGS. When the operation mode switching command device 19 installed on the ground side and connected to the ground-side vehicle information transmission device 18 is in the “normal” position, it has the same function as the conventional train operation system and operates.

  When the driver 23 becomes unable to control the train 13 and a deadman device (not shown) installed in the on-board cab 1 operates, a deadman device operation signal is sent from the vehicle-side vehicle information transmission device 16. When the ground side vehicle information transmission device 18 receives the deadman device operation signal, the operation mode switching command device 19 can be manually switched from the “normal” operation mode position to the “emergency” operation mode position. When the operation mode switching command device 19 is in the “emergency” operation mode position, emergency command information is sent from the ground side vehicle information transmission device 18. The emergency command information is received by the vehicle-side vehicle information transmission device 16 and detected by the ATC receiver 2. Upon receiving the emergency command information, the train 13 detects whether the emergency command information has been received, the ATC receiving unit 2 determines whether the own train is in the “emergency” operation mode state, and detects the “emergency” operation mode state. In this case, a switching command (electric signal) from the “normal” operation mode position to the “emergency” operation mode position is given to the operation mode switching device 14. In the operation mode switching device 14, an electric circuit (ground cab command circuit) is constructed so that a train can be operated by operating the ground cab 20 in response to a command to switch to the “emergency” operation mode position.

  A detailed illustration of the ground cab 20 is shown in FIG. The ground cab 20 has the same configuration as the on-vehicle cab 1 and includes a monitor device 24 and a ground master controller 25. The ground master controller 25 can give a slow driving command and a brake command, for example, in response to an operation by the operator.

  When a ground cab command circuit is constructed in the train 13, the section from the current location of the train 13 to the nearest station or target position is set to move at a slow speed, and the traveling speed of the train is controlled by the ATC.

  In addition, when a deadman device operation signal is sent from the train 13, cameras 15 installed in four locations outside the train (each in the front / rear and left / right directions of the train 13) and in five locations in the train (four directions in the cab and cabin) Shoot the situation. The captured camera image is sent from the vehicle-side vehicle information transmission device 16 installed on the train 13 to the ground-side vehicle information transmission device 18 and is displayed on the monitor device 24 of the ground cab 20.

  The above state is maintained, and the train 13 is moved to the nearest station or target position by operating the ground controller 25 while confirming the status of the train 13 by the monitor device 24 from the ground side driving device side. Can do.
