Specifically, for example, the control unit 31 controls, as predetermined signals, a display start signal indicating that the next station will be reached soon from an in-vehicle display device (not shown) mounted on the railway vehicle 21, and A signal indicating that the train 21 is stopped (speed is zero) and a door open/close signal of the railroad car 21 are received. Lighting of the LED 12 is started when receiving the signal, and the LED 12 is extinguished when the railway vehicle 21 stops and the door of the railway vehicle 21 is opened.

Note that the control unit 31 may be configured using a CPU or may be configured using a logic circuit. Alternatively, a CPU or the like mounted on the railroad vehicle 21 may function as the control unit 31 .

In the present invention, instead of automatically turning on/off the irradiation unit 11 by the control unit 31, the driver may manually turn on/off the irradiation unit 11 using a manual switch or the like.

According to the present embodiment, the irradiation unit 11 provided in the railway vehicle 21 irradiates a luminous flux toward a local area outside the vehicle determined according to the current position of the railway vehicle 21, and is irradiated with the luminous flux. The local irradiated region R is an index indicating the current position of the railroad vehicle 21 formed outside the railroad vehicle 21 so that the driver of the railroad vehicle 21 can directly visually recognize it.

According to the present embodiment, the local irradiated region R outside the vehicle by the luminous flux emitted from the railroad vehicle 21 is used as an index indicating the current position of the railroad vehicle 21. By directly looking at R, the current position of the railcar 21 can be easily confirmed.

Therefore, when stopping the railway vehicle 21 at a predetermined stop position, the driver can use the index R formed by the index forming device 1 according to the present embodiment to stop the railway vehicle 21 in the same manner as in the conventional method of stopping the railway vehicle. , compared to the case of using the position of the driver himself, the position of the window frame of the driver's cab, and the position of the structure of the railway vehicle visible through the window as an index indicating the current position of the railway vehicle, the current position of the railway vehicle 21 can be easily and easily determined. Accurate confirmation is possible, and thus the driver can more easily and accurately stop the railcar 21 at a predetermined stop position.

Specifically, when the driver stops the railroad vehicle 21 at a predetermined stop position, the driver checks the current position of the railroad vehicle by directly looking at the index R, and moves to the predetermined stop position. stop. At this time, the driver stops the railway vehicle 21 according to the line-shaped notation L1 to L3 according to the line-shaped notation L1 to L3. can be stopped at the stop position of

Further, according to the present embodiment, since the cross-sectional shape of the light flux is linear, the current position of the railway vehicle can be easily recognized accurately while improving the visibility of the index indicating the current position of the railway vehicle. . However, in the present invention, the cross-sectional shape of the luminous flux emitted by the irradiation unit 11 is not limited to a line shape, and may be, for example, a square shape or a circular shape.

In the present embodiment, the luminous flux from the irradiation unit 11 forms a line extending in a direction substantially perpendicular to the traveling direction of the railway vehicle on the horizontal plane when it reaches the predetermined horizontal plane. Therefore, in the present embodiment, since the surface to be irradiated with the light flux from the irradiation unit 11 is the floor surface 22a of the platform 22 which is a substantially horizontal plane, the local irradiated area serving as an index indicating the current position of the railway vehicle 21 R forms a line extending in a direction substantially perpendicular to the traveling direction W of the railroad vehicle 21 . Therefore, according to the present embodiment, it becomes easier to recognize the current position of the railroad vehicle 21 more accurately.

Furthermore, according to the present embodiment, since the irradiation of the light beam by the irradiation unit 11 is automatically turned on and off, it is convenient for the driver without requiring any special operation, and the light beam is always irradiated. Therefore, it is possible to save power and reduce the possibility of causing nuisance light to the neighborhood.

Further, according to the present embodiment, since the irradiation of the light flux is performed at least from when the railway vehicle 21 is positioned at a predetermined position before the predetermined stop position to when it stops at the predetermined stop position, The indicator R can be used when the driver stops the railcar 21 .

This embodiment differs from the first embodiment in that the illuminating section 11 irradiates a local line-shaped region R on the ground surface with the light flux emitted from the illuminating section 11. The difference is that the orientation of the irradiation unit 11 (that is, the X-axis, the Y-axis and the Z-axis) is set with respect to the railway vehicle 21 so as to do so. The line-shaped illuminated area R is substantially orthogonal to the traveling direction of the railroad vehicle 21 and serves as an index indicating the current position of the railroad vehicle 21 . Since there are sleepers, railroad tracks, and crushed stones (not shown) on the ground surface in front of the railroad vehicle 21, the line-shaped irradiated region R actually has unevenness.

FIG. 16 to 19, elements that are the same as or correspond to elements in FIGS. 5 to 7 are denoted by the same reference numerals, and overlapping descriptions thereof will be omitted.

The index forming system 61 according to the present embodiment forms three indices indicating three mutually different target stop positions of the railway vehicle 21. , 72, 73. In the present embodiment, each of the irradiation units 71, 72, and 73 is configured in the same manner as the irradiation unit 11, and irradiates a light beam having a linear cross-sectional shape. In FIGS. 17 and 18, unlike FIGS. 6 and 7, the linear notations L1, L2, and L3 are not shown on the floor surface 22a of the platform 22. FIG.

In this embodiment, the irradiation units 71 , 72 , 73 are provided above the floor surface 22 a of the platform 22 . The irradiation unit 71 is installed on the floor surface 22a of the platform 22 so that the light flux emitted from the irradiation unit 71 irradiates a linear region L1' where the linear notation L1 is written. A linear illuminated area L1′ irradiated with the light flux from the illumination unit 71 serves as an index indicating one target stop position of the railroad vehicle 21, similar to the linear notation L1. The irradiation unit 72 is installed on the floor surface 22a of the platform 22 so that the light flux emitted from the irradiation unit 72 irradiates a linear region L2' where the linear notation L2 is written. A linear irradiated area L2′ irradiated with the light flux from the irradiation unit 72 serves as an index indicating another target stop position of the railway vehicle 21, similar to the linear notation L2. The irradiation unit 73 is installed on the floor surface 22a of the platform 22 so that the light flux emitted from the irradiation unit 73 irradiates a linear region L3' where the linear notation L3 is written. A linear irradiated region L3′ irradiated with the light flux from the irradiation unit 73 serves as an index indicating the remaining target stop position of the railroad vehicle 21, similar to the linear notation L3.

FIG. 20 is a schematic block diagram showing an index forming system 61 according to a seventh embodiment of the invention. The index forming system 61 according to this embodiment also includes a controller 74 in addition to the irradiation units 71 , 72 , and 73 . The control unit 74 controls the irradiation units 71, 72, and 73 so that the irradiation of the light beams by the irradiation units 71, 72, and 73 is automatically turned on and off (turning on and off of the LED 12) under the condition that they are not turned on at the same time. do.

Then, the control unit 74 receives operation management information held by a ground device such as an operation management device or information obtained from the railway vehicle 21 to be stopped as a predetermined signal, and based thereon, determines the three target stop positions. The irradiation unit 71 is selected from among the irradiation units 71, 72, and 73 according to the type and the number of trains of the railway vehicle 21 that is to be stopped at one of them so that the irradiation unit 71 irradiates the luminous flux. , 72, 73. In other words, a signal indicating which stop target position the railway vehicle 21 to be stopped should stop as a predetermined signal is received from the ground device or the railway vehicle 21, and based on this, the irradiation units 71, 72, . Of the 73, only the irradiating unit that forms an index indicating the stop target position to be stopped is selectively turned on.

In the present embodiment, the control unit 74 turns on and off the irradiation of the luminous flux by one of the irradiation units 71, 72, and 73 selected according to the type and number of trains of the railway vehicle 21. is automatically performed, and at least from the time when the railway vehicle 21 is positioned at a predetermined position in front of the target stop position until it stops near the target stop position, at least the irradiation The irradiation unit is controlled so that the unit irradiates the light flux. Information necessary for such control can be obtained as a predetermined signal from a management device on the ground side, from the vehicle side, or from various sensors.

In the present embodiment, when the driver stops the railroad vehicle 21 at a predetermined stop position, the driver checks the current position of the railroad vehicle by directly looking at the index R, and furthermore, determines the target stop position. While confirming the target stop position of the railway vehicle 21 by directly looking at any of the linear irradiated areas L1′, L2′, and L3′ that are indices indicating the railway vehicle 21, the railway vehicle 21 is stopped at the predetermined stop position. At this time, the driver aligns the linear irradiated region R with the linear irradiated region formed by selectively irradiating the linear irradiated regions L1′, L2′, and L3′. By stopping the railroad car 21 by pressing the railroad car 21, the railcar 21 can be stopped at a predetermined stop position very easily.

According to the present embodiment, the local irradiated areas L1′, L2′, and L3′ on the ground side by the luminous fluxes emitted from the irradiation units 71, 72, and 73 provided on the ground side cause the railway vehicle 21 to stop. It is used as an index indicating the target position. Therefore, this index is easier to see than the conventional target stop position and linear notations L1, L2, and L3 even when the surroundings are dark or it is raining. , and line-shaped notations L1, L2, and L3, which are buried in snow and cannot be seen. Furthermore, since the index formed by the index forming system 61 according to the present embodiment is an area irradiated by the light flux and is not a sign board like the conventional stop position target, Since restrictions on size, arrangement, etc. are reduced, it is easy to adopt a size, arrangement, etc. for enhancing visibility.

As described above, the index formed by the index forming system 61 according to the present embodiment is easier to see than the conventional stop position target and linear notations L1, L2, and L3. Therefore, when stopping the railway vehicle at a predetermined stop position, the driver can use the index formed by the index formation system 61 according to the present embodiment to use the conventional stop position target or linear notations L1 and L2. , L3, the target stop position of the railroad vehicle can be easily and accurately confirmed, and the driver can more easily and accurately stop the railroad vehicle at a predetermined stop position. Become.

Further, according to the present embodiment, since the cross-sectional shape of the light flux is linear, the target stop position of the railroad vehicle can be accurately recognized while enhancing the visibility of the index indicating the target stop position of the railroad vehicle 21. becomes easier. However, in the present embodiment, the cross-sectional shape of the luminous flux is not limited to a linear shape, and may be, for example, a square shape or a circular shape.

In the present embodiment, the irradiated area that serves as an index of the target stop position includes a partial area of the floor surface of the platform, a partial area of the wall surface of the platform, a partial area of the ceiling surface of the platform, And it may include one or more of the partial areas of the ground surface.

Further, according to the present embodiment, the irradiation of the light beams by the irradiation units 71, 72, and 73 is automatically turned on and off, and the light beams are not always irradiated, so power can be saved. can.

According to the present embodiment, at least the irradiation units 71 and 72 are operated until the railway vehicle 21 is positioned at a predetermined position before the predetermined stop target position until the railway vehicle 21 stops near the predetermined stop target position. , 73 so that the driver can use the index when stopping the railcar 21 .

According to the present embodiment, one of the plurality of index forming devices that respectively form indices indicating different target stop positions is selected according to the railway vehicle that is going to stop at one of the target stop positions. The irradiation of the irradiation unit of only the forming device is selectively turned on, and the irradiation of the irradiation units of the other index forming devices is turned off, so that the driver forms only the index indicating the target stop position for his own vehicle. . Therefore, according to the present embodiment, compared to the case where a plurality of indices indicating mutually different target stop positions are formed at the same time, the index to be used becomes obvious at a glance, and the vehicle is stopped at the wrong target stop position. This eliminates the fear, and thus allows the driver to more easily and accurately stop the railway vehicle at the predetermined stop position.

In the present invention, one platform 22 may have only one stop target position. In this case, only one irradiation section may be used without using a plurality of irradiation sections.

Moreover, the index forming system 61 according to the present embodiment does not necessarily have to be used in combination with the index forming apparatus according to the first embodiment. For example, the driver may stop the railroad vehicle 21 at a position where an alternatively formed area among the linear irradiated areas L1', L2', and L3 is right beside him/herself.

The display lamps 85 to 86 are provided on the wall surface 22b of the platform 22 so as to be easily seen by the driver, corresponding to the linear notations L1, L2, and L3, respectively.

The control unit 88 receives from the outside a predetermined signal indicating which of the line-shaped notations L1, L2, and L3 should stop the railway vehicle 21 to be stopped at a target stop position indicated by one of the sensors 82 to 84. When a detection signal is obtained from the sensor corresponding to the target stop position to be made, the corresponding display lamp among the display lamps 85 to 86 is lit. Therefore, the lighting of the display lamp informs the driver that the railcar 21 has arrived at the target stop position where it should be stopped.
