Description

Railway indicator

The present invention relates to a railway or train destination indicator.

Previously known railway displays are usually implemented using drop-leaf technology and are suspended from the platform roof in the immediate vicinity of the track area.

Modern train displays using flip-screen technology provide information regarding train departure, train route, train composition and train type.

Although the railway displays in use today offer a rich range of information compared to earlier railway displays, the railway displays in use today no longer seem to meet the trend towards modern rail transport, both in terms of technology and the range of information that can be displayed.

It is therefore the object of the present invention to provide an improved track indicator that is able to display a wide range of information and yet can be placed in the usual locations, in order to be able to replace previous track indicators without great effort.

This object is solved by the subject matter of claim 1.

Preferred embodiments of the invention are the subject of the subclaims.

The present invention is based on the knowledge that, for reasons of compatibility with previously used track indicators,

systems, it is advantageous to provide a solution in which the previous dimensions for train displays can be retained, so that even previously standard housings can be used and the improved train display can be attached to the previously standard suspensions in the platform area. In order to achieve the inventive object of creating a train display that can display an expanded range of information, the present invention provides for the use of plasma screens instead of the previously standard flip-screen technology, on which almost any information can be displayed. According to the invention, two preferably colored plasma screens are provided for each train display, at least one of which is designed in 16:9 format and has a diagonal dimension of at least 106 cm. This large screen is used at least to display the previous information regarding departure time, train route, train type, etc. Additional information can be displayed on the other plasma screen, whereby moving images in particular can be shown, for example to show an incoming train, etc.

According to the invention, plasma screens are used to achieve a low installation depth and to enable the railway display to be set up in the immediate vicinity of the track area. Incoming trains cause very high electromagnetic fields in the platform area. The present invention is based on the knowledge that tube screens are too strongly disturbed by these fields and therefore cannot display a permanent, high-quality image in the platform area.

By using a plasma screen instead of flip-screen technology, it is possible to display any video images in addition to the usual train information. In particular, the solution according to the invention makes it possible to display advertising films at times when a train-specific display is not necessary. This is particularly the case when no train is currently arriving or departing from the platform in question. In particular, the use of two screens also enables a supporting image display on the second screen while train-specific information is being displayed on the main screen, in order to make the information displayed overall more clear and interesting. Preferably, at times when expected trains are approaching the platform, this can be displayed visually on the smaller screen to inform passengers that a train is arriving.

In the following, a preferred embodiment of the track indicator according to the invention is explained in more detail with reference to the accompanying drawings. The drawings show in detail:

Fig. 1 is a front view of the preferred embodiment,

Fig. 2 a view from the front with the cover opened, and

Fig. 3 is a side view of the preferred embodiment, also with the covers opened.

Fig. 1 shows a front view of the preferred embodiment of the track indicator according to the invention. The embodiment has a housing 1 into which two color plasma screens 2 and 3

are installed. The plasma screen 2 has a 16:9 format with a diagonal dimension of at least 106 cm. The plasma screen 3 has a 4:3 format and is significantly smaller in size than the screen 2. The screens are arranged next to each other as shown, which means that there is enough space for a platform sign 4 due to the smaller size of the screen 3. In order to enable the train information to be read from any direction, the preferred embodiment also has a corresponding structure from the back, i.e. corresponding plasma screens 2 and 3 are also provided on the back. In total, four screens are therefore provided per train display.

As can be seen from Fig. 2, the housing 1 has covers 5 and 6 for the front and back. These covers have windows 7, which allow the screens built into the housing to be viewed even when the covers are folded down. The screens 2 and 3 have their own housings 8 and 9, which reliably protect the plasma screens and the associated electronics against the effects of the weather. The screens 2 and 3 are attached to an inner frame 10 and 11 within the housing 1 and can be removed from it in a simple manner. In the event that a plasma screen fails, it can therefore be easily replaced by the station staff with a new, functioning screen.

Fig. 3 shows the preferred embodiment from the side. Again, the housing 1 and the two opened covers 5 and 6 can be seen. In the free space below the smaller screen 3 shown in Fig. 2, there is a power supply.

Part 12 is provided, which provides the power necessary to operate the two screens.

Claims (5)

Protection claims: 1. Track indicator with a housing (1), at least one digital plasma flat screen (2) with an aspect ratio of 16:9 and a diagonal diameter of at least 106 cm, at least one further digital plasma flat screen (3), wherein the at least two plasma flat screens are interchangeably mounted in the housing and are each installed in their own weatherproof housing (8, 9). 2. Track indicator according to claim 1, characterized in that the at least one further digital plasma flat screen has an aspect ratio of 4:3 and is significantly smaller than the plasma flat screen with an aspect ratio of 16:9. 3. Track indicator according to claim 1 or 2, characterized in net that the track indicator is designed on two sides, so that it has at least two plasma flat screens on the front and at least two corresponding plasma flat screens on the back. 4. Track indicator according to one of claims 1 to 3, characterized in that the at least two plasma flat screens are operated at a frequency of 60 Hz. 5. Track indicator according to one of the preceding claims, characterized in that the housing has at least one cover (5) which can be opened to have access to the plasma flat screens mounted in the housing of the track indicator, the cover (5) having transparent sections (7) corresponding to the position of the screens, which in When the housing is closed, you can see the built-in plasma flat screens.
