Is done. In such a conventional movement prohibition signal, the place where the prohibition signal flag is posted is stipulated by the rules for each site, and the movement prohibition signal is given to the leading vehicle on the upstream side or the downstream side, or the leading vehicle on the side close to the crew seat. A flag is posted. At the site, it is stipulated that when the driver goes up to the cab, the rule is to go up from the step where the movement prohibition signal flag is posted, so that the worker will notice the movement prohibition signal flag naturally in the work flow Efforts are being made. As a result, even if the driver tries to move the vehicle without noticing the movement prohibition signal flag, the pseudo mascon key is inserted into the keyhole where the mascon key is inserted, so that the driver can notice that the vehicle is prohibited from moving. it can.

Registered Utility Model No. 3087551 (paragraph number 0014 and FIG. 1)

  In the conventional movement prohibition signal, various measures have been taken at each site to make the staff aware of the prohibition of movement of the vehicle, but all depend on the attention of the staff, so a certain effect can be expected but the staff confirms If the operation was overlooked, it was difficult to completely prohibit the movement of the vehicle. For example, in a train zone where the vehicle can move in either direction on the top or bottom line, even if a movement prohibition signal flag is posted on the leading vehicle on the upstream side, crew members are prohibited from moving when moving from the leading vehicle on the downstream side. There is a risk of overlooking the signal flag. In addition, since the staff who post the movement prohibition signal flag knows the rules such as the train district to which they belong, they will post the movement prohibition signal flag at the designated posting location, but the crew member who confirms the movement prohibition signal flag will not move. There is a risk of overlooking the flag for prohibition of movement because it goes in and out of the different train zones where the flags are displayed and the rules are different.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a block diagram of a vehicle including a vehicle movement prohibition system according to an embodiment of the present invention.
The movement prohibition system 21 is a system for prohibiting the movement of the vehicle when performing work on the vehicle. As shown in FIG. 1 , the movement prohibition system 21 includes a drive device 8, a control device 9, a master controller 22, a switching device 23, a display device 24, a spare battery device 25, a parking brake device 26, , An emergency brake device 27, a shut-off device 28, a low pressure circuit 29, a pantograph lifting device 30, a pantograph 31, a high voltage circuit 32, and the like.

  For example, when the switching device 23 switches to the movement prohibited state, the control device 9 displays a signal indicating that the vehicle is working on the display device 24, or the brake is released during the brake test operation so that the vehicle When activated, the emergency brake device 27 is operated, the low-pressure circuit 29 is shut off, and the pantograph 31 is prohibited from rising. The master controller 22 is a master controller that commands control of powering, braking, and the like by a driver's steering operation. The switching device 23 is a work switch that switches the vehicle to a movement-inhibited state when performing work, and is installed in the cab of the vehicle and functions in the entire knitting when switched at one place during knitting. The display device 24 is a device that displays a signal indicating that the vehicle is working when the switching device 23 is switched to the movement prohibited state. The display device 24 displays, for example, “Movement prohibited” on the display screen of the cab of the vehicle, emits an LED or the like installed near the switching device 23 when the switching device 23 is turned on, The vehicle side indicator lamps installed on the both sides of the vehicle having the stand are respectively turned on. The spare battery device 25 is a device that supplies power to the display device 24 and the like when the high voltage circuit 32 is not pressurized and a load is applied to the battery device.

  The parking brake device 26 is a brake that operates when preventing the wheels from rolling when the vehicle is stopped, and the emergency brake device 27 is a brake that operates in an emergency. The shut-off device 28 is a change-over switch that shuts off the low-voltage circuit 29, and makes it impossible to turn on and off the battery device when the switch device 23 switches the vehicle to the movement-inhibited state. The low voltage circuit 29 is a circuit to which a voltage lower than the voltage of the overhead wire is applied. The low-voltage circuit 29 is, for example, a battery device that supplies electric power necessary for starting the vehicle, and functions as a power source necessary for the operation of equipment in the vehicle. The pantograph elevating device 30 is a device that raises and lowers the pantograph 31 and raises the pantograph 31 with the electric power from the low voltage circuit 29. The pantograph 31 is a device that receives power from an overhead line. The high voltage circuit 32 is a circuit to which power from the overhead line is supplied through the pantograph 31. When power is supplied from the overhead line, the high voltage circuit 32 operates a generator (not shown) to charge the battery device of the low voltage circuit 29.

Next, the operation of the vehicle movement prohibition system according to the embodiment of the present invention will be described.
FIG. 2 is a flowchart for explaining the operation of the vehicle movement prohibition system according to the embodiment of the present invention.
In step (hereinafter referred to as S) 100, it is determined whether or not the switching device 23 is turned on. When the operation is performed on the vehicle with the vehicle stopped, the vehicle is switched to the movement prohibited state when the switching device 23 is turned on. The control device 9 determines whether or not the switching device 23 is turned on. When the switching device 23 is turned on, the process proceeds to S200, and when the switching device 23 is turned off, the series of operations is terminated.

  In S200, the parking brake device 26 is activated. When the switching device 23 is turned on, the control device 9 activates the parking brake device 26 to prevent the vehicle from rolling. In S300, the emergency brake device 27 is activated. When the switching device 23 is turned on, the control device 9 operates the emergency brake device 27.

  In S400, the low voltage circuit 29 is confirmed. The control device 9 confirms whether the low pressure circuit 29 is pressurized or not. When an operation for changing the state of the low-voltage circuit 29 is performed, the control device 9 invalidates such an operation. For example, the control device 9 prohibits an operation that turns on and off the battery device.

  In S500, the pantograph 31 is not allowed to rise and the pantograph 31 is allowed to fall. When the high voltage circuit 32 is not pressurized, the pantograph 31 is separated from the overhead wire, and the vehicle is in a low voltage state. As a result, if the pantograph 31 is brought into contact with the overhead line to bring the vehicle to a high voltage state, there is a risk of danger to the operator, and the control device 9 prohibits the pantograph 31 from being lifted by the pantograph lifting device 30. When the vehicle is a pneumatic vehicle, the control device 9 prohibits starting of the internal combustion engine. On the other hand, when the high voltage circuit 32 is pressurized, the pantograph 31 is in contact with the overhead wire and the vehicle is in a high voltage state. As a result, even if the pantograph 31 is separated from the overhead line and the vehicle is in a low voltage state, there is less danger to the operator, so the control device 9 permits the pantograph 31 to descend by the pantograph lifting device 30. When the vehicle is a pneumatic vehicle, the control device 9 permits the stop of the internal combustion engine.

  In S600, the movement prohibition state is displayed. The control device 9 causes the display device 24 to display a signal indicating that the vehicle is working and is not allowed to move.

  In S700, it is determined whether or not the high voltage circuit 32 is pressurized. When the high voltage circuit 32 is pressurized, the pantograph 31 is in contact with the overhead wire, and power is supplied from the overhead wire to the high voltage circuit 32. The control device 9 determines whether or not the high voltage circuit 32 is pressurized. When the high voltage circuit 32 is pressurized, the process proceeds to S800, and when the high voltage circuit 32 is not pressurized, the series of operations is terminated.

  In S800, it is determined whether or not to perform a start-up test. When the master controller 22 is operated by the driver and the control device 9 determines that the start-up test is performed, the process proceeds to S900, and when the control device 9 determines that the start-up test is not performed, the process proceeds to S1000.

  In S900, a start-up test is performed. Since the parking brake device 26 and the emergency brake device 27 are operated in S200 and S300, the vehicle does not move even if the driver operates the main controller 22 to perform the activation check.

  In S1000, it is determined whether or not to perform a brake test. When the control device 9 determines that the master controller 22 is operated by the driver and the brake test is performed, the process proceeds to S1100. When the control device 9 determines that the brake test is not performed, the series of operations is terminated.

  In S1100, the relaxation check is performed and the emergency brake device 27 is released. At the time of the brake test, it is necessary to release the emergency brake device 27 because it is necessary to confirm the release of the brake.

  In S1200, it is determined whether or not the power controller notch is turned on by operating the master controller 22 by the driver. The control device 9 determines whether or not the power running notch for turning the vehicle into a running state is turned on. When the power running notch is turned on, the process proceeds to S1300, and when the power running notch is turned off, the process proceeds to S1400.

  In S1300, the emergency brake device 27 is activated. Since the emergency brake device 27 is released at the time of confirming the release, there is a possibility that the vehicle starts to move when the power running notch is turned on. For this reason, when the power running notch is turned ON, the control device 9 immediately activates the emergency brake device 27 to prevent the vehicle from moving.

  In S1400, a brake test is performed. When the power running notch is OFF, there is no possibility that the vehicle starts to move. Therefore, when the driver operates the brake handle of the master controller 22, the control device 9 controls the brake device based on a command from the brake handle. And make a brake test.

The vehicle movement prohibition system according to the embodiment of the present invention has the following effects.
(1) In this embodiment, the switching device 23 switches the vehicle to the movement-inhibited state when working on the vehicle, and the parking brake device 26 of the vehicle when the switching device 23 switches the vehicle to the movement-inhibited state. And the emergency braking device 27 is operated by the control device 9. As a result, since the movement of the vehicle is prohibited by a simple operation, the work on the vehicle can be performed safely.

(2) In this embodiment, the control device 9 forcibly operates the emergency brake device 27 when the brake is released and the vehicle is started during the brake test operation. As a result, when the power running notch is turned ON and the vehicle is started when confirming the release of the brake, the emergency brake device 27 can be actuated immediately to prevent the vehicle from moving.

(3) In this embodiment, when the switching device 23 switches the vehicle to the movement prohibited state, the display device 24 displays a signal indicating that the vehicle is working. As a result, the staff can be notified that the vehicle is working and is in a movement-inhibited state.

(4) In this embodiment, when the switching device 23 switches the vehicle to the movement prohibited state, the low voltage circuit 29 of this vehicle is prohibited from being turned on and off. As a result, the low pressure circuit 29 cannot be pressurized and unpressurized, so the state of the low voltage circuit 29 does not change, and the battery device of the low voltage circuit 29 cannot be turned on and off. Further, it is possible to prevent the pantograph lifting device 30 from raising the pantograph 31 by the electric power supplied from the low voltage circuit 29. As a result, since the pantograph 31 can be prevented from contacting the overhead line, the state of the high voltage circuit 32 does not change and the vehicle can be prevented from switching to the high voltage state.

(5) In this embodiment, when the switching device 23 switches the vehicle to the movement prohibited state, the control device 9 prohibits the rise of the pantograph 31 of this vehicle. As a result, it is possible to prevent power from being supplied from the overhead wire to the high voltage circuit 32 through the pantograph 31 and the vehicle to be in a high voltage state, so that the worker can perform the work safely.

(6) In this embodiment, when the switching device 23 switches the vehicle to the movement prohibited state, the control device 9 prohibits the start of the internal combustion engine of the vehicle. As a result, when the vehicle is a pneumatic vehicle, the internal combustion engine of the pneumatic vehicle can be prevented from starting.

The present invention is not limited to the embodiment described above, and various modifications or changes can be made as described below, and these are also within the scope of the present invention.
(1) Although this embodiment has been described by taking a train or a diesel car as an example, the present invention can also be applied to a passenger car towed by an electric locomotive or an internal combustion locomotive. In this embodiment, the railway vehicle has been described as an example, but the present invention can also be applied to other transportation vehicles such as automobiles, airplanes, and ships.

( 2 ) In this embodiment, the parking brake device 26 and the emergency brake device 27 are operated in S200 and S300, but only the parking brake device 26 can be operated. In this embodiment, the spare battery device 25 is operated in S500, but the spare battery device 25 may be omitted. In this case, if the display device 24 is operated when the high voltage circuit 32 is not pressurized, a load is applied to the battery device constituting the low voltage circuit 29. For this reason, when the low-pressure circuit 29 is not pressurized, the operation of the display device 24 can be omitted.
