  On the side surface of the lower end portion of the underframe A, a plurality of illumination units 31 to 41 are provided along the traveling direction of the maintenance vehicle 1. In the maintenance vehicle 1 equipped with the vehicle speed fluctuation display system according to the present embodiment, eleven lighting units 31 to 41 are provided from the front to the rear of the underframe A. The illumination units 31 to 41 are provided not only on the left side toward the front of the maintenance car 1 shown in FIG. 1, but also on the right side toward the front of the maintenance car 1 (not shown).

  The control units 100 and 101 further set lighting conditions of the first lighting unit and the second lighting unit when the maintenance car 1 is moving forward and when the maintenance car 1 is moving backward. The first lighting unit and the second lighting unit are controlled to change. As a result, the worker can know the operation of the maintenance car 1 by visually observing the first lighting unit and the second lighting unit.

  Next, the illumination units 31 to 41 will be described in detail. 2 and 3 are explanatory diagrams of the lighting patterns of the sequential lighting of the lighting units 31 to 41 of the maintenance vehicle 1 equipped with the vehicle speed fluctuation display system according to the embodiment of the present invention. 4 to 6 are explanatory diagrams of different lighting patterns of the sequential lighting of the lighting units 31 to 41 of the maintenance vehicle 1 equipped with the vehicle speed fluctuation display system according to the embodiment of the present invention.

The illumination units 31 to 41 are provided as lower lights on the side surface of the lower end portion of the underframe A of the maintenance car 1 and illuminate the lower side and the side of the maintenance car 1. The illumination units 31 to 41 have a long shape having a fixed length in the front-rear direction of the maintenance vehicle 1, and each of the illumination units 31 to 41 has a plurality of light emitting bodies S1 to S4 such as LEDs. They are aligned in the front-rear direction of the maintenance car 1 (see FIGS. 1 to 6).
In the maintenance vehicle 1 equipped with the vehicle speed fluctuation display system according to the present embodiment, the lighting units 31 to 41 are lit in a pattern of all lighting, sequential lighting, and extinguishing according to the vehicle speed and traveling direction of the maintenance vehicle 1 Thus, the control units 100 and 101 can control the illumination units 31 to 41.

Here, the sequential lighting refers to a lighting pattern that repeats lighting and extinguishing so that the lighting units 31 to 41 flow from one side of the maintenance car 1 to the other side.
For example, when the maintenance car 1 is moving forward, all the illumination units 31 to 41 in FIG. 2A are in the off state, only the illumination unit 41 in FIG. 2B is on. 2 (c), only the illumination unit 39 of FIG. 2 (d) is illuminated, only the illumination unit 38 of FIG. 2 (e) is illuminated. 2 (f), only the illumination unit 36 of FIG. 2 (g) is illuminated, only the illumination unit 35 of FIG. 2 (h). A state in which only the illumination unit 34 in FIG. 2 (i) is illuminated, a state in which only the illumination unit 33 in FIG. 2 (j) is illuminated, only the illumination unit 32 in FIG. 2 (k) Is a lighting pattern which repeats the state where only the illumination part 31 of FIG. 2 (l) is lighting.
The lighting pattern as described above is used in the maintenance vehicle 1 equipped with the vehicle speed fluctuation display system according to the present embodiment when the maintenance vehicle 1 is moving forward at 6 to 29 km / h.

  Similarly, in the maintenance vehicle 1 equipped with the vehicle speed fluctuation display system according to the present embodiment, when the maintenance vehicle 1 is moving backward at 6 to 29 km / h, all of FIG. 3 (b), only the lighting unit 32 of FIG. 3 (c) is lighted, and FIG. A state in which only the illumination unit 33 in (d) is on, a state in which only the illumination unit 34 in FIG. 3 (e) is on, a state in which only the illumination unit 35 in FIG. 3 (g) is illuminated, only the illumination unit 37 of FIG. 3 (h) is illuminated, and only the illumination unit 38 of FIG. 3 (i) is illuminated. The state in which only the illumination unit 39 in FIG. 3 (j) is on, the state in which only the illumination unit 40 in FIG. 3 (k) is on, the illumination in FIG. 3 (l) Only part 41 is lighting pattern that repeats a state of light.

The lighting patterns of the illumination units 31 to 41 as described above are implemented by the control units 100 and 101 instructing the illumination units 31 to 41. That is, the control units 100 and 101 determine the vehicle speed and the traveling direction (the vehicle speed and traveling direction of the maintenance vehicle 1) of the first truck C1 from the electric signal input from the rotary encoder (not shown). At that time, in the maintenance vehicle 1 equipped with the vehicle speed fluctuation display system according to the present embodiment, when the maintenance vehicle 1 is moving at 0 to 5 km / h, the lighting units 31 to 41 are all turned on, and the maintenance vehicle Control is performed so that the lighting units 31 to 41 are sequentially turned on when 1 is moving at 6 to 29 km / h, and the lighting units 31 to 41 are turned off when the maintenance car 1 is moving at 30 km / h or more The units 100 and 101 control the illumination units 31 to 41. Furthermore, depending on the traveling direction, a lighting pattern of sequential lighting is implemented which is either forward movement shown in FIG. 2 or reverse movement shown in FIG.
Here, when the maintenance car 1 is moving at 0 to 5 km / h, the lighting units 31 to 41 are all turned on while moving alongside the maintenance car 1 on the side of the maintenance car 1 This is to provide illumination for workers who work. The reason for sequentially lighting the illumination units 31 to 41 when the maintenance car 1 is moving at 6 to 29 km / h is to alert the worker that the maintenance car 1 is moving at a low speed and to call attention It is. On the other hand, when the maintenance car 1 is moving at 30 km / h or more, the illumination units 31 to 41 are turned off because the moving speed of the maintenance car 1 is high and lighting is not necessary.

  Here, the control units 100 and 101 are provided with a memory unit (not shown), and the memory unit stores a rewritable program. Therefore, the control units 100 and 101 implement the lighting patterns of the illumination units 31 to 41 as described above by executing the program stored in the memory unit. Therefore, the lighting units 31 to 41 can implement different lighting patterns by rewriting a program or storing a plurality of programs for implementing different lighting patterns in the memory unit and selecting an arbitrary program.

  For example, the lighting pattern as shown in FIG. 4 may be implemented instead of the lighting pattern as described above. That is, in the lighting pattern shown in FIG. 4, when the maintenance car 1 is moving forward, only the lighting unit 41 of FIG. 4 (a) is lighting, only the lighting unit 40 of FIG. 4 (b) A state in which only the illumination unit 39 in FIG. 4C is on, a state in which only the illumination unit 38 in FIG. 4D is on, only the illumination unit 37 in FIG. 4 (f), only the illumination unit 35 of FIG. 4 (g) is illuminated, illumination unit 34 of FIG. 4 (h). 4 (i), only the lighting unit 33 of FIG. 4 (j) is lighted, and the lighting unit 32 of FIG. 4 (k). Repeat the state in which only 31 is on. Even with sequential lighting having such a lighting pattern, a worker located on the side of the maintenance car 1 can appropriately recognize the traveling direction of the maintenance car 1. In addition, the lighting pattern shown in FIG. 4 corresponds to the case where there is no state where the illumination parts 31 to 41 of FIG. 2A are turned off in the lighting pattern shown in FIG. Therefore, in the lighting pattern shown in FIG. 4, since any of the illumination units 31 to 41 is always on, the worker can easily grasp the position of the maintenance car 1. Similarly, in the lighting pattern shown in FIG. 3, the lighting pattern in which the illumination units 31 to 41 in FIG. 3A do not have a state of turning off may be implemented.

As an example of a further lighting pattern, a lighting pattern as shown in FIG. 5 and FIG. 6 may be used. That is, in the lighting pattern shown in FIG. 5, when the maintenance car 1 is moving forward, the state in which all the lighting units 31 to 41 in FIG. 5A are extinguished, the lighting unit in FIG. 5 (c), only the illumination parts 39 and 40 of FIG. 5 (d) are lit, FIG. In the state where only the illumination parts 38 and 39 in e) are lit, in the state where only the illumination parts 37 and 38 in FIG. 5 (f) are lit, only the illumination parts 36 and 37 in FIG. 5 (h), only the illumination units 34 and 35 of FIG. 5 (i) are illuminated, the illumination unit of FIG. 5 (j). A state in which only 33 and 34 are on, a state in which only the illumination units 32 and 33 in FIG. 5 (k) are on, the illumination in FIG. 5 (l) State in which only 31 and 32 is lit, repeat the state where only the illumination unit 31 of FIG. 5 (m) is on. Thus, a lighting pattern may be used in which two adjacent lighting units light simultaneously.
Moreover, as shown in FIG. 6, when the maintenance car 1 is moving forward, a state in which all the lighting units 31 to 41 in FIG. 6 (a) are extinguished, the lighting unit 41 in FIG. 6 (b) 6 (c), only the illumination units 38 and 39 of FIG. 6 (d) are illuminated, FIG. 6 (e). 6 (f), only the illumination units 32 and 33 of FIG. 6 (g) are illuminated. It is possible to repeat the state in which only the illumination unit 31 of FIG. 6 (h) is on. In this case, the two adjacent lighting units are simultaneously turned on, and the advancing direction of the lighting units which are on is faster than in the case of FIG.
Moreover, in the lighting pattern of FIG.5 and FIG.6, you may eliminate the state which light-extinguishes all the illumination parts 31-41 like the example of FIG. Also in this case, since any of the illumination units 31 to 41 is always on, the worker can easily grasp the position of the maintenance car 1.

  When the above-described sequential lighting is performed, the lighting intervals of the lighting units 31 to 41 can be set arbitrarily. For example, from the state of FIG. 2 (a), FIGS. 2 (b), 2 (c), 2 (d), 2 (e), 2 (f), 2 (g) and 2 (h). 2 (i), FIG. 2 (j), FIG. 2 (k) and FIG. 2 (l), each time interval is a predetermined number of seconds (e.g., 0.5). 2 (a) to the state shown in FIG. 2 (b), or may be displayed for a predetermined number of seconds (for example, 0.5 seconds). It may be a short time interval that changes from the state of 2 (a) to the state of FIG. 2 (l) through the states of FIGS. 2 (b) to 2 (k). This time interval can be changed as appropriate by rewriting the program stored in the memory unit or selecting any setting from among the programs stored in advance. This applies not only to FIG. 2 but also to the examples shown in FIGS. 3 to 6 and the following modifications.

  As described above, the lighting units 31 to 41 provided on the side surface of the maintenance car 1 are all turned on, lighted in a predetermined lighting pattern by sequential lighting, or turned off according to the vehicle speed and traveling direction of the maintenance car 1 Therefore, a worker located on the side of the maintenance car 1 can immediately grasp the information on the operation of the maintenance car 1.

  Here, the light emitters S1 to S4 of the first lighting unit, the second lighting unit, and the lighting units 31 to 41 are preferably LED lighting from the viewpoint of durability and energy conversion efficiency. If electrical control by 101 is possible, any lighting device such as a fluorescent lamp, an incandescent lamp, and a halogen lamp can be used. Further, the color of the LED is not particularly limited, but, for example, yellow, blue, orange and the like can be optionally used according to the application.

  Next, structural features of the illumination units 31 to 41 will be described in further detail, taking the illumination unit 31 as an example.

  As described above, the lighting unit 31 has a function of illuminating the lower part and the side of the maintenance car 1 in addition to the function of indicating the vehicle speed and the traveling direction of the maintenance car 1 as described above. Therefore, it is desirable that the irradiation angle of the illumination unit 31 be inclined toward the track bed rather than parallel to the track bed. Assuming that the irradiation angle when the irradiation angle of the illumination unit 31 is parallel to the track is 0 ° and the irradiation angle when the lighting unit 31 vertically irradiates the track is −90 °, the irradiation angle is 0 ° to It is preferable that it is about -90 degrees. Furthermore, it is more preferable that it is about -20 degrees--70 degrees. This means that the closer the irradiation angle is to 0 °, the easier it is for the worker located on the side of the maintenance car 1 to visually recognize the irradiation light of the illumination unit 31, and the closer the irradiation angle is to -90 °. The reason is that the area around the maintenance car 1 can be illuminated brighter. In particular, when the irradiation angle is about -20 ° to -70 °, the illumination unit 31 serves as a lower light of the maintenance car 1 and for maintenance to workers located on the side of the maintenance car 1 The vehicle speed of the car 1 and the role of displaying the traveling direction can both be played most efficiently. The same applies to the illumination units 32-41.

The installation height of the illumination unit 31 is not particularly limited as long as the worker located on the side of the maintenance car 1 can recognize the illumination light of the illumination unit 31. For example, the installation height is about 30 to 150 cm from the bottom of the rail R Is preferred. This is because it is easier for the worker to perceive the illumination light of the illumination unit 31 when the illumination light of the illumination unit 31 is closer to the worker's line of sight on the side surface of the maintenance car 1. The same applies to the illumination units 32-41.
In addition, the irradiation angle of the illumination parts 31-41 is not necessarily limited to about 0 degree--90 degrees, and can be suitably changed according to the needs of a work site. For example, about 0 degree-90 degrees may be sufficient, and 45 degrees-about 45 degrees may be sufficient.

Further, among the lighting units 31 to 41, the lighting units 31 and 41 corresponding to the front end side and the rear end side of the maintenance car 1 are provided at the front end and the rear end of the side of the lower end of the underframe A. By arranging, it is possible to make a worker located on the side of the maintenance car 1 recognize the full length of the maintenance car 1.
In addition, even if it is not possible to provide the illumination units 31 and 41 at the forefront and the rear end of the side surface of the lower end portion of the underframe A, it is about 80% of the total length of the underframe A If the lighting units 31 to 41 are disposed across the vehicle, it is possible to make a worker located on the side of the maintenance car 1 recognize the approximate total length of the maintenance car 1. In addition, in order to make a worker located at the side of the maintenance car 1 recognize the approximate total length of the maintenance car 1, as described above, 8 of the total length of the underframe A (full length of the maintenance car 1) Although it is preferable that the illumination parts 31 to 41 be disposed over a relatively small extent, the present invention is not limited to this. For example, the ratio of the lighting units 31 to 41 with respect to the total length of the underframe A is particularly to alert a worker located on the side of the maintenance car 1 that the maintenance car 1 is moving. It is not limited. That is, the illumination units 31 to 41 do not necessarily have to be provided over about 80% of the total length of the frame A.

  In the maintenance vehicle 1 equipped with the vehicle speed fluctuation display system according to the above embodiment, each of the illumination units 31 to 41 includes a plurality of light emitters S1 to S4, and illumination is performed when the illumination units 31 to 41 are sequentially lit. Although light-emitting-body S1-S4 provided in each of the parts 31-41 operate | moves by the pattern of either all lighting or light extinction, this invention is not this limitation. FIGS. 7-9 is explanatory drawing of the lighting pattern of the sequential lighting of the illumination part 31 of the maintenance vehicle 1 carrying the vehicle speed fluctuation display system which concerns on the modification of embodiment of this invention. In the maintenance vehicle 1 equipped with the vehicle speed fluctuation display system according to the modification of the embodiment of the present invention, only the lighting pattern of the sequential lighting of the illumination units 31 to 41 mounted the vehicle speed fluctuation display system according to the embodiment Since this is different from the maintenance vehicle 1, the description of the same configuration as that of the maintenance vehicle 1 equipped with the vehicle speed fluctuation display system according to the above embodiment will be omitted.

  In the maintenance vehicle 1 equipped with the vehicle speed fluctuation display system according to the present modification, each of the plurality of light emitters S1 to S4 provided in each of the illumination units 31 to 41 changes from one of the maintenance vehicles 1 to the other. The programs of the control units 100 and 101 are revised so as to have a lighting pattern in which lighting and extinction are repeated so as to flow.

  That is, in the lighting pattern shown in FIG. 7, when the maintenance car 1 is moving forward, the light emission of FIG. 7B is started from the state in which all the light emitters S1 to S4 of FIG. A state in which only the body S1 is on, a state in which the light emitters S1 and S2 in FIG. 7 (c) are on, a state in which only the light emitter S4 in FIG. 7 (d) is off, FIG. The state in which all the light emitters S1 to S4 are turned on is repeated to provide a lighting pattern that makes the lighting part appear to be moving forward.

Even with sequential lighting having such a lighting pattern, a worker located on the side of the maintenance car 1 can appropriately recognize the traveling direction of the maintenance car 1.
Note that all of the light emitters S1 to S4 of the lighting units 31 to 41 may simultaneously move as shown in FIG. 7, or after the light emitters S1 to S4 of the lighting unit 41 are in the state of FIG. The light emitters S1 to S4 of the illumination unit 40 are changed to the state of FIG. 7 (e) from the state of FIG. 7 (b) through the states of FIG. 7 (c) to FIG. 7 (d). The light emitters S1 to S4 are changed from the state of FIG. 7B through the states of FIG. 7C to FIG. 7D to the state of FIG. S1 to S4 are changed to the state of FIG. 7 (e) from the state of FIG. 7 (b) through the states of FIGS. 7 (c) to 7 (d), and all the light emitters S1 to S4 of the illumination units 31 to 41 are The light emitters S1 to S4 of the illumination units 31 to 41 may move in a series until the light emission state is turned on.
In addition, when the maintenance car 1 reverses, as shown in FIG. 8, the lighting parts are reverse by moving the light emitters S1 to S4 in the reverse movement to the case shown in FIG. 7. I can show it. Further, when moving backward, as in the case of moving forward described in the example of FIG. 7, all the light emitters S1 to S4 of the lighting units 31 to 41 may simultaneously move as shown in FIG. The 41 light emitters S1 to S4 may move in a series.
Also, in the maintenance vehicle 1 equipped with the vehicle speed variation display system according to the present modification, as shown in the maintenance vehicle 1 equipped with the vehicle speed variation display system according to the above embodiment, for example, as shown in FIG. 7 (a) may be changed to a state shown in FIG. 7 (b) in a predetermined number of seconds (for example, 0.5 seconds). 7 (b) to 7 (d) to a state shown in FIG. 7 (e) may be a short time interval changing between predetermined seconds (for example, 0.5 seconds) .

According to the lighting pattern of the sequential lighting of the lighting units 31 to 41 of the maintenance vehicle 1 equipped with the vehicle speed fluctuation display system according to the modification of the embodiment of the present invention as described above, individual lighting of the light emitters S1 to S4 By controlling the pattern by the control unit 100, 101, it is possible to realize the lighting pattern of the detailed light emitters S1 to S4.
