  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 variation display system according to the present embodiment, eleven illumination units 31 to 41 are provided from the front to the rear of the frame A. The illumination units 31 to 41 are provided not only on the left side of the maintenance vehicle 1 as shown in FIG. 1 but also on the right side of the maintenance vehicle 1 (not shown).

Next, the 1st illumination part not shown provided in the front end part of the frame A and the 2nd illumination part not shown provided in the rear end part of the frame A are demonstrated.

When the maintenance vehicle 1 is moving forward, the first illumination unit is a headlamp and the second illumination unit is a tail lamp. On the other hand, when the maintenance vehicle 1 is moving backward, the first illumination unit is a tail lamp and the second illumination unit is a headlamp.
Since the maintenance vehicle 1 equipped with the vehicle speed variation display system of the present embodiment does not have a self-propelling function, when the maintenance vehicle 1 moves forward, a locomotive (not shown) or the like is not shown in the first coupler D1. And the maintenance vehicle 1 is pulled forward, or a locomotive (not shown) is connected to the second connector D2 and the maintenance vehicle 1 is pushed forward.

  A rotary encoder (acquisition unit) (not shown) is provided on the first axle L3 of the first carriage C1, and the number of rotations of the first axle L3 is converted into an electric signal. Alternatively, the control units 100 and 101 are input to 101 (hereinafter, abbreviated as “control units 100 and 101”), so that the control units 100 and 101 have the vehicle speed and the traveling direction of the first carriage C1 (the vehicle speed and the traveling direction of the maintenance vehicle 1). Determine.

  The control units 100 and 101 further determine the lighting conditions of the first illumination unit and the second illumination unit when the maintenance vehicle 1 is traveling forward and when the maintenance vehicle 1 is traveling backward. The first illumination unit and the second illumination unit are controlled to change. As a result, the operator can know the operation of the maintenance vehicle 1 by viewing the first illumination unit and the second illumination unit.

  Next, the illumination units 31 to 41 will be described in detail. 2 and 3 are explanatory diagrams of sequential lighting patterns of the lighting units 31 to 41 of the maintenance vehicle 1 equipped with the vehicle speed variation display system according to the embodiment of the present invention. 4-6 is explanatory drawing of the lighting pattern from which the sequential lighting of the illumination parts 31-41 of the maintenance vehicle 1 carrying the vehicle speed fluctuation display system which concerns on embodiment of this invention differs.

The illumination units 31 to 41 are provided as a headlight on the side surface of the lower end portion of the frame A of the maintenance vehicle 1 and illuminate the lower side and the side of the maintenance vehicle 1. The illumination units 31 to 41 have a long shape having a certain length in the front-rear direction of the maintenance vehicle 1, and each of the illumination units 31 to 41 includes light emitters S <b> 1 to S <b> 4 such as a plurality of LEDs. They are arranged in the front-rear direction of the maintenance vehicle 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 illumination units 31 to 41 are lit in a pattern such as full lighting, sequential lighting, and extinguishing according to the vehicle speed and traveling direction of the maintenance vehicle 1. Thus, the control parts 100 and 101 can control the illumination parts 31-41.

Here, the sequential lighting means a lighting pattern in which lighting and turning off are repeated so that the lighting units 31 to 41 flow from one side of the maintenance vehicle 1 to the other side.
For example, when the maintenance vehicle 1 moves forward, all the illumination units 31 to 41 in FIG. 2A are turned off, and only the illumination unit 41 in FIG. 2B is turned on. 2C, only the illumination unit 40 in FIG. 2C is lit, only the illumination unit 39 in FIG. 2D is lit, and only the illumination unit 38 in FIG. 2E is lit. 2, only the illumination unit 37 in FIG. 2F is lit, only the illumination unit 36 in FIG. 2G is lit, only the illumination unit 35 in FIG. 2 is turned on, only the illumination unit 34 in FIG. 2 (i) is lit, only the illumination unit 33 in FIG. 2 (j) is lit, only the illumination unit 32 in FIG. 2 (k). It is a lighting pattern which repeats the state which lights up, and the state which only the illumination part 31 of FIG.2 (l) lights.
The lighting pattern as described above is used when the maintenance vehicle 1 is moving forward at 6 to 29 km / h in the maintenance vehicle 1 equipped with the vehicle speed fluctuation display system according to the present embodiment.

  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 rearward at 6 to 29 km / h, all of FIG. From the state in which the illumination units 31 to 41 are turned off, only the illumination unit 31 in FIG. 3 (b) is lit, only the illumination unit 32 in FIG. 3 (c) is lit, FIG. FIG. 3D shows a state in which only the illumination unit 33 is lit, a state in which only the illumination unit 34 in FIG. 3E is lit, a state in which only the illumination unit 35 in FIG. 3 (g) only the lighting unit 36 is lit, only the lighting unit 37 of FIG. 3 (h) is lit, only the lighting unit 38 of FIG. 3 (i) is lit, The state where only the illumination unit 39 of FIG. 3 (j) is lit, the state where only the illumination unit 40 of FIG. 3 (k) is lit, the illumination of 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 when the control units 100 and 101 command the illumination units 31 to 41. That is, the control units 100 and 101 determine the vehicle speed and the traveling direction of the first carriage C1 (the vehicle speed and the traveling direction of the maintenance vehicle 1) from the electrical signal input from a 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 lit, and the maintenance vehicle 1 The lighting units 31 to 41 are sequentially lit when 1 is moving at 6 to 29 km / h, and the lighting units 31 to 41 are turned off when the maintenance vehicle 1 is moving at 30 km / h or more. The units 100 and 101 control the lighting units 31 to 41. Further, depending on the traveling direction, a sequential lighting pattern of either forward movement shown in FIG. 2 or backward movement shown in FIG. 3 is performed.
Here, when the maintenance vehicle 1 is moving at 0 to 5 km / h, the lighting units 31 to 41 are all turned on while moving alongside the maintenance vehicle 1 on the side of the maintenance vehicle 1. This is to provide lighting for workers who work. When the maintenance vehicle 1 is moving at 6 to 29 km / h, the lighting units 31 to 41 are sequentially lit so that the worker can recognize that the maintenance vehicle 1 is moving at a low speed and call attention. It is. On the other hand, when the maintenance vehicle 1 is moving at 30 km / h or more, the lighting units 31 to 41 are turned off because the moving speed of the maintenance vehicle 1 is fast and lighting is unnecessary.

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

  For example, instead of the above lighting pattern, a lighting pattern as shown in FIG. 4 may be implemented. That is, in the lighting pattern shown in FIG. 4, when the maintenance vehicle 1 is moving forward, only the illumination unit 41 in FIG. 4A is lit, only the illumination unit 40 in FIG. The lighting state, the state where only the illumination unit 39 of FIG. 4C is lit, the state where only the illumination unit 38 of FIG. 4D is lit, the illumination unit 37 of FIG. 4E only Is lit, only the illumination unit 36 in FIG. 4 (f) is lit, only the illumination unit 35 in FIG. 4 (g) is lit, and the illumination unit 34 in FIG. 4 (h). 4 is turned on, only the illumination unit 33 in FIG. 4 (i) is lit, only the illumination unit 32 in FIG. 4 (j) is lit, the illumination unit in FIG. 4 (k). The state where only 31 is lit is repeated. Even with sequential lighting having such a lighting pattern, a worker located on the side of the maintenance vehicle 1 can appropriately recognize the traveling direction of the maintenance vehicle 1. The lighting pattern shown in FIG. 4 corresponds to the lighting pattern shown in FIG. 2 when the lighting units 31 to 41 in FIG. Therefore, in the lighting pattern shown in FIG. 4, any one of the lighting units 31 to 41 is always lit, so that the worker can easily grasp the position of the maintenance vehicle 1. Similarly, in the lighting pattern shown in FIG. 3, a lighting pattern in which the lighting units 31 to 41 in FIG.

As an example of a further lighting pattern, a lighting pattern as shown in FIGS. 5 and 6 may be used. That is, in the lighting pattern shown in FIG. 5, when the maintenance vehicle 1 moves forward, all the illumination units 31 to 41 in FIG. 5A are turned off, and the illumination unit in FIG. 5 is a state where only 41 is lit, a state where only the illumination units 40 and 41 in FIG. 5C are lit, a state where only the illumination units 39 and 40 in FIG. 5D are lit, FIG. Only the illumination units 38 and 39 in FIG. 5F are lit, only the illumination units 37 and 38 in FIG. 5F are lit, and only the illumination units 36 and 37 in FIG. 5, only the illumination units 35 and 36 in FIG. 5 (h) are lit, only the illumination units 34 and 35 in FIG. 5 (i) are lit, and the illumination unit in FIG. 5 (j). The state in which only 33 and 34 are lit, the state in which only the illumination units 32 and 33 in FIG. 5 (k) are lit, 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. In this way, a lighting pattern in which two adjacent illumination units are simultaneously lit may be used.
Further, as shown in FIG. 6, when the maintenance vehicle 1 is moving forward, all the illumination units 31 to 41 in FIG. 6A are turned off, and the illumination unit 41 in FIG. 6B. Only the lighting units 40 and 41 in FIG. 6C are lit, only the lighting units 38 and 39 in FIG. 6D are lit, FIG. ) Only the lighting units 36 and 37 are lit, only the lighting units 34 and 35 in FIG. 6 (f) are lit, only the lighting units 32 and 33 in FIG. 6 (g) are lit. The state in which only the illumination unit 31 in FIG. 6H is lit may be repeated. In this case, two adjacent illumination units are lit at the same time, and the illuminating unit that is lit is faster in the traveling direction than in the case of FIG.
Moreover, in the lighting pattern of FIG.5 and FIG.6, you may eliminate the state which all the illumination parts 31-41 turn off like the example of FIG. Also in this case, since any one of the illumination units 31 to 41 is always lit, the worker can easily grasp the position of the maintenance vehicle 1.

  When such sequential lighting is performed, the lighting intervals of the illumination units 31 to 41 can be arbitrarily set. For example, from the state of FIG. 2A, FIG. 2B, FIG. 2C, FIG. 2D, FIG. 2E, FIG. 2F, FIG. 2G, and FIG. ), FIG. 2 (i), FIG. 2 (j), FIG. 2 (k), and FIG. 2 (l), each time interval changing in order is a predetermined number of seconds (for example, 0.5 2) may be a long time interval that changes from the state of FIG. 2A to the state of FIG. 2B, or during 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 an arbitrary setting from 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 vehicle 1 are turned on or off in a predetermined lighting pattern by full lighting or sequential lighting depending on the vehicle speed and traveling direction of the maintenance vehicle 1. Therefore, an operator located on the side of the maintenance vehicle 1 can immediately grasp information regarding the operation of the maintenance vehicle 1.

  Here, the light emitters S1 to S4 of the first illumination unit, the second illumination unit, and the illumination units 31 to 41 are desirably LED illuminations from the viewpoint of durability and energy conversion efficiency, but the control unit 100, 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. In addition, the color of the LED is not particularly limited, but, for example, yellow, blue, orange, or the like can be arbitrarily used according to the application.

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

  As described above, the illumination unit 31 has a function of illuminating the lower side and the side of the maintenance vehicle 1 in addition to the function of indicating the vehicle speed and the traveling direction of the maintenance vehicle 1 as described above. Therefore, it is desirable that the illumination angle of the illumination unit 31 is inclined toward the road bed rather than an angle parallel to the road bed. If the illumination angle of the illumination unit 31 is parallel to the road bed, the illumination angle is 0 °, and the illumination angle when the illumination unit 31 illuminates the road bed vertically is −90 °, the illumination angle is 0 ° to It is preferably about −90 °. Further, it is more preferably about −20 ° to −70 °. This is because the closer the irradiation angle is to 0 °, the easier it is to see the irradiation light of the illumination unit 31 from the worker located on the side of the maintenance vehicle 1, and the closer the irradiation angle is to −90 °. This is because the area around the maintenance vehicle 1 can be illuminated more brightly. In particular, when the irradiation angle is about −20 ° to −70 °, the illumination unit 31 serves as a lower light for the maintenance vehicle 1 and is used for maintenance by workers located on the side of the maintenance vehicle 1. The role of displaying the vehicle speed and the traveling direction of the vehicle 1 can be most efficiently achieved. The same applies to the illumination units 32 to 41.

Although the installation height of the illumination part 31 will not be specifically limited if the worker located in the side of the maintenance vehicle 1 can recognize the illumination light of the illumination part 31, for example, it is about 30-150 cm from the bottom part of the rail R. Is preferred. This is because it is easier for the worker to recognize the illumination light of the illumination unit 31 when the illumination light of the illumination unit 31 is closer to the eyes of the worker on the side surface of the maintenance vehicle 1. The same applies to the illumination units 32 to 41.
In addition, the irradiation angle of the illumination parts 31-41 is not necessarily limited to about 0 degree--90 degree, It can change suitably according to the needs of a work site. For example, it may be about 0 ° to 90 °, or about 45 ° to −45 °.

In addition, among the lighting units 31 to 41, the lighting units 31 and 41 corresponding to the most advanced side and the last end side of the maintenance vehicle 1 are provided at the most advanced side and the last end of the side surface of the lower end portion of the underframe A. By disposing, the worker located on the side of the maintenance vehicle 1 can recognize the entire length of the maintenance vehicle 1.
Moreover, even if it is a case where the illumination parts 31 and 41 cannot be provided in the forefront and the rear end of the side surface of the lower end part of the frame A, about 80% of the full length of the frame A (the total length of the maintenance vehicle 1). If the lighting units 31 to 41 are arranged over the distance, the worker positioned on the side of the maintenance vehicle 1 can recognize the approximate total length of the maintenance vehicle 1. In addition, in order to make the worker located on the side of the maintenance vehicle 1 recognize the approximate total length of the maintenance vehicle 1, as described above, the total length of the base frame A (the total length of the maintenance vehicle 1) is 8 Although it is preferable that the illumination parts 31-41 are arrange | positioned over about percent, this invention is not this limitation. For example, in order to recognize and alert the worker located on the side of the maintenance vehicle 1 that the maintenance vehicle 1 is moving, the ratio of the illumination units 31 to 41 with respect to the total length of the frame A is particularly It is not limited. That is, the illumination units 31 to 41 are not necessarily provided over about 80% of the total length of the frame A.

  In the maintenance vehicle 1 equipped with the vehicle speed variation display system according to the embodiment, each of the illumination units 31 to 41 includes a plurality of light emitters S1 to S4, and when the illumination units 31 to 41 are sequentially lit, The light emitters S1 to S4 provided in each of the units 31 to 41 operate in a pattern of full lighting or extinguishing, but the present invention is not limited to this. 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. Note that the maintenance vehicle 1 equipped with the vehicle speed fluctuation display system according to the modification of the embodiment of the present invention is equipped with the vehicle speed fluctuation display system according to the above embodiment only for the lighting patterns of sequential lighting of the lighting units 31 to 41. Since it 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 embodiment is omitted.

  In the maintenance vehicle 1 equipped with the vehicle speed fluctuation display system according to this modification, each of the plurality of light emitters S1 to S4 provided in each of the illumination units 31 to 41 is changed from one side of the maintenance vehicle 1 to the other. The programs of the control units 100 and 101 have been revised so that the lighting pattern repeats lighting and extinction so as to flow.

  That is, in the lighting pattern shown in FIG. 7, when the maintenance vehicle 1 is moving forward, the light emission of FIG. 7B from the state where all the light emitters S1 to S4 of FIG. The state in which only the body S1 is lit, the state in which the light emitters S1 and S2 in FIG. 7C are lit, the state in which only the light emitter S4 in FIG. The lighting pattern in which all of the light emitters S1 to S4 are turned on is repeated, and the lighting location is shown to be moving forward.

Even with sequential lighting having such a lighting pattern, a worker located on the side of the maintenance vehicle 1 can appropriately recognize the traveling direction of the maintenance vehicle 1.
Note that all the light emitters S1 to S4 of the illumination units 31 to 41 may simultaneously move as shown in FIG. 7, or after the light emitters S1 to S4 of the illumination unit 41 are in the state of FIG. The light emitters S1 to S4 of the illumination unit 40 change from the state of FIG. 7B to the state of FIG. 7E through the states of FIG. 7C to FIG. 7D, and then the illumination unit 39. The light emitters S1 to S4 of FIG. 7B change from the state of FIG. 7B to the state of FIG. 7E through the states of FIG. 7C to FIG. 7D. S1 to S4 change from the state of FIG. 7B to the state of FIG. 7E through the states of FIG. 7C to FIG. 7D, and all the light emitters S1 to S4 of the illumination units 31 to 41. The light emitters S <b> 1 to S <b> 4 of the illumination units 31 to 41 may move continuously until is turned on.
Further, when the maintenance vehicle 1 moves backward, as shown in FIG. 8, the light-emitting parts S1 to S4 perform reverse movements as shown in FIG. Can show.
