The sequencer processor 2 is also connected to the digital switch 4 to perform timer setting, flicker setting, manual / automatic switching setting, and the like. A power supply unit 5 is connected to the relay circuits R (1) to R (n) and the display blocks B1 to Bn, and the AC power is rectified and DC power is supplied. By such a control circuit, lighting of the thread line is controlled in various modes.

  In this embodiment, in contrast to the conventional lighting control in which every eight lightings are extended, the display lighting switching unit is performed in half (every four) or one quarter (every two). Therefore, the display is sharp and the visibility is improved.

  The lighting sequence of the display blocks B1, B2,... Of the display unit is controlled by the relay circuits R (1) to R (n). The relay is driven by the control signal to control the lighting mode. FIG. 3 shows the supply timing of the switching signal supplied to the LED display unit and lighting the display LED.

  The four display blocks B1 to B4 constitute the first display unit, the display blocks B5 to B8 constitute the second display unit, and the display blocks B9 to B12 constitute the third display unit.

Subsequently, the pulse signal is supplied to the display block B8 of the second display unit, the display block B12 of the third display unit,... At the same timing as the pulse signal supplied to the display block B4. In this way, the pulse signal is supplied to each display block and lighting is controlled, so that passengers in the platform can visually recognize the flow of light along the traveling direction (entrance direction) of the train.

  Similar lighting control is performed when the two display blocks shown in FIG. That is, the pulse signals are sequentially supplied to the display blocks B1 and B2 of the first display unit, but the pulse signals are sent to the first display block after the second display unit at the same timing as the pulse signal supplied to the display block B1. To be supplied. In addition, the pulse signal is supplied to the second display block after the second display unit at the same timing as the pulse signal supplied to the display block B2.

  As described above, in this embodiment, the light flow is created by controlling the lighting of each display block of the display unit in units of four display blocks or two display blocks.

  In the present invention, there are various types of lighting control other than those described above, such as lighting time, dimming, blinking, blinking cycle, display color, and the like.

The display unit installed along the edge of the platform controls the lighting of the display unit from a predetermined time (tens of seconds to several minutes) before the train entry time on the platform of the station.

  In an embodiment of the present invention, a train is approached to a passenger by displaying a thread line that flows along the traveling direction of the train by controlling the lighting of the display block as described above from a certain time before the train enters the platform. , You can easily see the approach. By changing the period of the pulse signal supplied to the display block, the flow speed of this flowing thread line can be slowed down to indicate that the train is still far away, or immediately after increasing the flow speed. It is also possible to display that the train is approaching nearby. If the approach is still ahead before the thread line is displayed, the passenger can first be alerted with a red display.

  In addition, it is possible to display the entrance / exit of the train that stops at the platform using a special color. If the display color indicating the approach of the train and the entrance / exit is changed according to the type of the train entering and arriving, efficient display is possible. For example, it is easy to visually recognize if the green display is a rapid display, the red is a limited express, and the blue is an express.

  Furthermore, the type of entrance / exit of a train, for example, a priority seat or a female-only entrance / exit, can be displayed in a light emitting color different from the display of other entrances / exits to clearly indicate the type of entrance / exit.

  The display flowing through the display unit may be a special pattern (for example, red high-speed display) when the emergency button is operated. It can also be a guide light for evacuating to a safe place using a display that flows in the event of a fire and emergency.

  In this way, the display unit can specify and display the type of train that enters the home, passes through the platform, and stops, for example, normal, rapid, new rapid, express, express, semi-express, forwarding, etc., by the emission color. it can. Of course, the entrance / exit can also be determined according to the type of the next approaching train.

  The display unit is configured by an LED display unit, but can also be configured to include a lens that focuses emitted light.

  It goes without saying that a flashing operation is included as a mode of displaying in place of or in combination with the lighting operation.

  The display unit is arranged along the edge of the platform, but it is natural in terms of power consumption that only the length section of the next incoming train is actually operated to display the entrance. Considered.
