Field of application of the invention

The invention relates to an arrangement for warning approaching rail vehicles and is preferably applicable to track construction sites of industrial railways. *. ,

Characteristic of the known technical solutions

Arrangements are known for warning track construction brigades in front of approaching rail vehicles, which are attached by train detectors which are attached to or next to the rails at a safe distance from the construction site and connected by wire or punk to a central unit. This central unit detects and processes the train approach and triggers via another device, the so-called warning device, an acoustic and visual signaling of the track construction rig, so that the required safety measures can be carried out in time.

The known arrangements for warning track construction rigs fulfill their task only when the train detectors respond, the operating system of the train traffic, the track system and the terrain having no influence. These arrangements therefore have the disadvantage that their functional safety depends solely on the reliability of the train detectors and the possibility of arrangement at a safe distance. Furthermore, access by unauthorized persons can not be ruled out. ·

Another major disadvantage of the known arrangements is that the train detectors are discharged from the track construction rig, mounted and 3 ^e after construction progress, including the appropriate cable to the transmission device to be implemented! When using track-laying machines with a working speed of approx. 1 km / h, the constant implementation can only be achieved with a high workload.

For smaller repairs to switches or track switching with frequent change of location, the use of warning devices of known design is not acceptable because of the excessive cost. . ' . ' ,. . ' , ".- Also known are automatic train controls for state railways using track switches, train number reporting facilities, Linienzugbeeinflussungen u." a. Also known are facilities from the railway safety technology, which are used for the train operation while driving on intact track systems by the train movements of interlockings by, the operation of track layouts are specified. For this purpose, there are arrangements and facilities, which mediate partly via process computers and with the use of train radio trains from signal box to interlocking and transfer data about the trains, such as speed, direction, destination, location and signal positions. Thus, the interlocking of a track system from a defined state on movements of trains specified and guaranteed. The disadvantage of these known devices with respect to an inclusion of track construction sites is that for track construction sites from the track layout of a signal box, the corresponding block sections are only locked against a train ride. The train movements in the adjacent tracks are automatic and without any restrictions · The attention of the safety posts is crucial for avoiding the risks of track construction brigades due to passing trains. · Especially for industrial railways in mining companies with rapid and / or irregular train sequences, the attention of the safety post is often overwhelmed »

Object of the invention

The aim of the invention is to avoid as far as possible accidents by train approach to track construction sites and to reduce the workload for the track safety ·

Explanation of the essence of the invention

The object of the invention is to provide, using the state of railway safety technology, an arrangement which eliminates the costly use of train detectors.

According to the invention, the object is achieved in that the track construction site is entered as a "slow-moving train" in the train operating system by the required control is made in the simplest Pail by hand in the corresponding block section of the track image of a signal box · There are control signals via a Bausteilenspeicherschaltung to train access control Track image given · These control signals block only optional train trips on the construction site and / or in the neighboring tracks and cause that already at the train control via the Fahrtensteller and driving test at least at a safe distance from the construction site for each colliding with the construction site in the neighboring track / Baustellengieis train ride corresponding control command is formed by an evaluation circuit, the time delay via a radio or wire transmission device ultimately the warning device of the construction site in the absence of acknowledgment by the Sicherhe causes it to trigger. The acknowledgment takes place via a suitable speech connection. In the transmission channel of the speech connection, every construction site has a different identification code at several construction sites.

This arrangement and sequence of warning the track construction rigs before the train starts, but at the latest in block sections secured minimum distances to the site a time staggering Zugnäherungen notified individually or in groups your safety post the site, so that when trains in close succession or on View several unnecessary site clearances are avoided. With a pre-selection stage for radio control of the interlocking s can be decided on whether single or Gruppenmelduhg eifolgt. The control command for Zugannäherüng formed in the evaluation circuit can be used to make the Zugfunkeinrichtung influencing the train in such a way that a signal lamp or a notification tone to the driver on construction sites points or * receives a message from the signal box by message and the absence of acknowledgment Slow speed of the train comes into effect · '. , :

In pure inCW radio communication and corresponding channel control through the interlocking the speech connection between the security post and the driver can be made ,, '

A construction site 3 is marked in the interlocking 5 by pressing ZeilenanWahltasten 11 and SpaltanWahltasteü 12 on the track 10 by the possible location corresponding track illumination 9 of the site by the actuated line selection keys 11 and Spaltenariwahltasten 12

the position of the construction site 9 is entered into a construction site storage 16 at "previous triggering of the start button 14 via a storage drive unit 13. The reading of the construction site 9 into the construction site storage 1β is completed by actuation of the storage key 15, whereby by previous input, if necessary! Site track 2 or when changing the site 9 or Fehltastung deletion can be made. ]

The site coordinates defined in the site memory Ί6 are visualized via a track illumination 17 in the track 10, the type of track illumination for the site 9 statements about track closure, conditionally navigable construction site track 2, train ride in siding 1 or approach of the train 4 to the site or a Fault in the train warning permits. Through this information, the interpreter / process computer can give the required commands to train 4 and 3 site. For situation-oriented information presentation of the train traffic on the track 10 1st requirement that on the well-known train control 19 and the driving 3traßenstell- and test device 18 and by the existing track in the track switching means 8 in the route selection by the Fahrstraßenstellglieder with the outputs of the construction site memory 16 a conjunctive Linking takes place in such a way that site-oriented control of the track pattern 10 or the radio center 24 takes place.
