Abstract

PURPOSE: To improve display effect of a display ana display approach of a train accurately by displaying the train-approacn when detecting it and also varying this display condition in accordance with the train-approach position. CONSTITUTION: An alarm 2 and a crossing gate 3 are equipped in a railroad crossing 1 set on a rail R. A plurality of train detectors S1-S5 are arranged on the rail R just in front of or behind the railroad crossing. A display 4 is arranged on a pole of the alarm 2 ana enables it to display large and small various arrows A1-A2. The alarm 2 is started to alarm by a controller C and also a cross gate bar 3a of the crossing gate 3 is lowered in accordance with approach of a train T to the railroad crossing 1. Respective arrows A1-A4 corresponding to respective train detectors S1-S4 are sequentially displayed in accordance with detection of passing of the train T by the respective train detectors S1-S4. Whereby, display effect of the display 4 can be improved and approach of the train T can be displayed accurately.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a train approach display device which is provided at a railroad crossing or a platform of a station to inform the approach state of a train.

[0002]

2. Description of the Related Art Conventionally, a railroad crossing is provided with an alarm device that lights a lamp and sounds an alarm when a train enters a warning start section of a certain distance in front of the railroad crossing. A breaker is provided to prevent it.

Further, the platform of the station is provided with an indicator such as an indicator light indicating that a train is approaching.

[0004]

However, although the above-mentioned conventional train approach indicator can see that the train is approaching the railroad crossing or platform, it does not know how close the train is.
There was a defect that it lacked guideability.

Therefore, the present invention has been made to solve the above-mentioned drawbacks, and an object of the present invention is to provide a train approach display device for indicating the approach state of a train.

[0006]

In order to achieve the above object, a train approach display device according to the present invention includes train detection means for detecting the approach state of a train to a predetermined place such as a railroad crossing or a platform of a station. A display means installed at the predetermined place for indicating that the train approaches, and a display control means for changing the display state of the display means in correspondence with the approaching position of the train detected by the train detection means. It is characterized by having. Further, the display control means is characterized by changing the size of the display state of the display means. The display control means changes the display position of the display means.

[0007]

In the above structure, the display control means causes the display state of the display means to correspond to the approaching position of the train detected by the train detection means, and changes the display size or the display position for display.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1A is a schematic configuration diagram of an apparatus according to an embodiment, in which a railroad crossing 1 is provided at a predetermined position of a rail R.

The railroad crossing 1 is provided with an alarm device 2 and a breaker 3 as in the well-known railroad crossing. In addition, for example, Japanese Patent Laid-Open No. 60-18444 or Japanese Utility Model Laid-Open No. 2-606 is provided on the rail R before the train T advances to the railroad crossing 1.
A plurality of (four in the illustrated example) well-known train detectors S1 to S4 for detecting the axle position of the train T to detect the train position, as shown in Japanese Patent Publication No. 69, are provided at predetermined intervals. In addition, a train detector S5 is provided at a predetermined position in the direction in which the train T advances from the railroad crossing 1.

The above train position detectors S1 and S5
Can also be used as a conventional train position detector using a track circuit in which a rail R for controlling an alarm and a breaker is a part of an electric circuit.

The indicator 4 is provided on the pole of the alarm device 2 and is constituted by arranging a large number of LED indicators in a plane. And this display 4 is controlled by the controller C.
As shown in FIG. 1 (b), arrows A1 having different sizes are used.
.About.A3 can be lit and displayed.

The controller C, in addition to controlling the display 4,
The alarm device 2 and the circuit breaker 3 can be controlled.

The control operation of the apparatus of this embodiment will be described below with reference to the flowchart of FIG.

Now, it is assumed that the train T is running toward the railroad crossing 1. Then, when the train T is detected by the train detector S1 (Yes at Step 100. Hereinafter, Step will be referred to as S). The ringing of the alarm device 2 is started and the blocking rod 3a of the circuit breaker 3 is lowered (S102). At this time, the display of the arrow on the display 4 is the largest as shown in (a) of FIG. 1B (S104; see arrow A1).

Therefore, a person passing by at the railroad crossing should know that the train T is approaching the railroad crossing 1 by sounding the alarm 2, descending the blocking rod 3a of the breaker 3 and displaying the display 4. You can

When the train T is detected by the train detector S2, the display 4 changes to the smallest arrow like the arrow A2 shown in Fig. 1 (b) at B (Yes at S106, S1).
08). The timing of change to this arrow A2 is determined so that the lowering of the shutoff rod 3a of the breaker 3 is almost completed. In other words, the train detector S2 is installed at the above-mentioned timing.

As the train T further approaches the railroad crossing 1, it is detected by the train detector S3 and then the train detector S4. Each time the train T is detected, the display on the display 4 is as shown in FIG.
1C, the arrow A3 has a medium size, and then, as shown in D of FIG. 1B, the arrow A1 has the largest value (Yes in S110, S112,
S114 affirmative, S116).

Therefore, a person waiting to pass the railroad crossing 1 can easily know how close the train T is to the railroad crossing 1 from the size of the arrow on the display 4.

When the train detector S5 detects that the train T has advanced from the railroad crossing 1, the alarm 2 stops ringing and the breaking bar 3a of the breaker 3 rises. And
The display on the display 4 is also turned off (Yes at S118, S12).
0).

FIG. 3 shows another display example of the display unit 4, in which the arrow T of a certain size is provided until the train T enters the alarm start section of the level crossing 1 and moves out from the level crossing 1. Is lit and displayed, and the positions of the lighting marks B1 to B4 are changed based on the detection signals of the train detectors S1 to S4, as shown in A to D of FIG.

Therefore, a person waiting for passage at the railroad crossing 1 can know the approaching state of the train T from the positions of the lighting marks B1 to B4.

In the above-mentioned embodiment, the example in which the display 4 is installed at the railroad crossing 1 is shown. However, when this is installed at the platform of the station, the user can check the approaching state of the train approaching the platform. Will be able to know.

Further, in the above example, the graphic displayed on the display 4 is an arrow, but the size may be changed to a circle, and other symbols or characters may be used. You may make it blink and light.
