Description

The invention relates to a device for rotting warning.

Rottenwarnanlagen for warning track workers of approaching Trains are divided into signal-independent warning systems and signal-dependent warning systems. In Germany and others European countries are in accordance with the accident prevention regulations for Speeds> 200 km / h signal-dependent warning systems required. With these systems, this can affect the construction site covering main signal or block signal can only be made when the rotting has generated a message to the signal box stating that the track is cleared. The known systems have the disadvantage that extensive changes and expansions made to the signal box have to be and a cable connection between signal box and Job on the track must be established.

A device for warning rotting is known from EP 0 286 627 A2, when setting commands from the signal box circuit as a rotten warning message by means of an interlocking system on the interlocking side to a construction site Outdoor facility will be transferred and the security post after Implementation of security measures on site Sends confirmation message from the outdoor area to the indoor area. The Signaling workers is safe from the signaling point of the indoor system controlled exit or block signal protected. One from the dispatcher Initiated command for the exit or block signal is only through the Acknowledgment message of the security item triggered. For each Interlocking type, a matching circuit must be developed, per track must be present. Special relay groups are required for relay signal boxes be developed that exist once for each track of the route have to. This requires considerable development effort and also will an expensive, additional hardware is required.

The object of the invention is to provide a simpler device for Creating a rotten warning and an associated process for the rotten warning.

This object is achieved by a device according to claim 1 and a method according to claim 7.

The device according to the invention has an interface to one Radio network via which at least one radio station can be contacted automatically is, for the purpose of warning track workers by radio about the approach of a train. The device according to the invention is advantageous designed as an ESTW interface module that can be connected via an interface is connected to an ESTW. The ESTW informs the ESTW interface module about the current locations, the occupancy of the Track sections and / or the ETCS position reports approaching trains including the associated track numbers. The ESTW interface module compares the information received with the previous one stored information about tracks on which track workers are active, e.g. at a construction site. When a train approaches the construction site, controlled by the ESTW interface module Track workers via radio, e.g. GSM-R, transmitted. The track workers are with Standard mobile phones equipped, e.g. GSM phones. The warning sign can be a predetermined phone, e.g. that of the site manager, and / or in a broadcast process all track workers at the same time be transmitted. Only after receiving an acknowledgment signal from Site manager, which confirms that no track worker is in the The relevant track is released and the approaching train can happen. This can increase security for communication between the site manager and the ESTW interface module coded radio transmission is used. On simple way can be used for coding random numbers which are determined before the transfer and only the Site manager and the ESTW interface module are known.

The invention is particularly suitable for use in the new ETCS system, ETCS = European Train Control System. At ETCS Level 3 you can the ESTW be replaced by RBC and the ESTW operator station by one RBC operator station, RBC = Radio Block Center. In contrast to ESTW, at which information about the trains to the ESTW using axle counters and electrical and / or optical lines are transmitted at the RBC the information about the trains is transmitted to the RBC by radio GSM-R - transmitted directly by trains, the trains information import via balises.

Only one device according to the invention is required per signal box. The intervention in the signal box only relates to a new one Interface. The commands to lock / unlock the tracks are generated in accordance with the commands of the existing ESTW. In this manner and way are no special software extensions or software changes required in the ESTW. On a cable connection from Signal boxes for the line can be dispensed with by using GSM. Site managers and track workers each have a cell phone, which means that On the one hand, information transfer is accelerated very quickly and can be done individually and on the other hand a locally flexible use of the Workers are possible even outside the call range. In the state of the art there is not access to the at all points along the route Cable connection to the signal box. This makes a chain of Security items needed until the next access point. Through the Using the cell phone is working at any point of the Route possible through a minimum number of track workers; a chain of There is no security item. By using a special Transfer method to secure the transfer - in advantageously by means of TAN numbers, TAN = transaction number - standard mobile radio stations can be used. So that is through the invention is an inexpensive and secure implementation of a Rotten warning reached.

The device according to the invention for rotting warning is thereby characterized that an interface to an electronic Interlocking module and an interface to a radio network is provided, that the device is capable of providing information about at least one train to be received by the electronic signal box module and saved with Compare information about at least one construction site area, and that the device is suitable in the event that a train joins Construction site area is approaching, a warning signal is automatically sent over the To send the radio interface to at least one radio telephone Call number is stored in the device. The information about a current construction site, e.g. Date, time, track section, will be before Commissioning entered into the device. The operator (Dispatcher) of the ESTW blocks the relevant track section for the entered period of time, e.g. 8:00 a.m. to 10:00 a.m. or 7:00 a.m. to Open end. Track workers moving during the period Are located via the warning signal via a approaching train warned. The warning signal is sent via radio sent out, at least one track worker, e.g. the site manager has one Radio telephone by means of which he can receive the warning signal.

The device according to the invention is advantageously characterized characterized in that the device is suitable for the case of Receipt of an acknowledgment signal on the warning signal, automatically one ESTW command to release the previously automatically locked Track section on which the train is approaching to generate and Send electronic signal box module. The site manager shows his Track workers start to leave the danger area. When this has happened it sends an acknowledgment signal to the device by radio. This is now informed that there is no longer any track worker in the danger zone located. The corresponding track can be released, the approaching train.

The device according to the invention is also advantageous in this way characterized in that the device is suitable for at least part of the Received acknowledgment signal with stored numbers or to compare a stored code and only the ESTW command generate when the at least part of the received Acknowledgment signal with a stored number or the stored code matches.

The first exemplary embodiment is explained with reference to FIGS. 1 and 2. Fig. 1 shows a schematic representation of an ESTW operator station and a device according to the invention.

Fig. 1 shows the arrangement of the devices required for an automatic Rotting warning via GSM mobile phones. The invention relates High-speed rail lines equipped with signal-dependent warning systems must be controlled by electronic signal boxes (ESTW) become. The electronic signal box contains regardless of the design usually an operator station and monitors as well as one Input option via mouse or keyboard. The existing ESTW operator station 8, which is also used as an ESTW workstation or ESTW display module can be designated with the device 7 according to the invention connected, which is designed as an ESTW interface module. Depending on Signal box design can be the interface between ESTW operator station 8 and ESTW interface module as a LAN connection or serial interface be executed. The ESTW interface module receives this interface the locations of the trains. To do this, the ESTW operator station 8 cannot be changed because the ESTW interface module on Listening to the data stream. If a speed information of the Trains in ESTW operator station 8 is available, this will also be transfer. Furthermore, the ESTW interface module is e.g. over a ISDN interface or directly connected to a GSM module 6, the one Has interface to the GSM network. The GSM network is e.g. that for that Rottenwarn procedure selected network of a provider or the network multiple providers. The ESTW interface module and the GSM module 6 can also be integrated in one device.

The following can also be used as a radio network instead of GSM: GSM-R, GPRS, EDGE, UMTS, company radio, etc.

The ESTW operator station 8 is also provided with several modules 3, 4, 5 connected, which can be designed as: input / output means, Monitor, keyboard, computer mouse, printer, etc. The ESTW operator station 8 is e.g. Part of a signal box operating room, a control center or a Operations center and is e.g. as a computer with a correspondingly special Software running. Instead of a computer, a computer system can also be used with at least two computers, e.g. three computers.

The ESTW interface module is also provided with several modules 1, 2 connected, which can be designed as: input / output means, Monitor, keyboard, computer mouse, printer, etc. The ESTW interface module is e.g. as a computer with corresponding special software executed. Instead of a computer, a computer system can also be used at least two computers, e.g. three computers. The ESTW interface module is programmed so that it has the appropriate Can perform functions. Programming is done e.g. by means of Programming language C ++.

Fig. 2 shows a schematic representation of two mobile devices.

One mobile device 10 is a GSM mobile radio station with a Interface to a portable computer 11 which e.g. executed as a laptop is. The other mobile device 9 is a GSM mobile radio station. The Mobile device 10 serves as an A mobile phone, mobile device 9 as a B mobile phone. For the Rottenwarn procedure is an A cell phone and at least one B cell phone provided, e.g. two, three, four or five B-cell phones.

If a construction site is to be set up on the track, it will be affected Track via an input device, e.g. Computer mouse or keyboard, on the ESTW interface module entered. In addition, an A cell phone for the Construction site selected and the number of the A cell phone together with saved on the construction site track. In the ESTW interface module furthermore advantageously a number of so-called TAN numbers a program for random numbers generated, printed out and together with the number of the A cell phone saved. The one for the construction site The responsible construction manager includes the printed TAN number list the construction site. On an electronic transmission of the TAN numbers waived for security reasons because the connection is being tapped could. If a second construction site is set up on the same signal box, so will also be the phone number of a selected, other A cell phone and that or the construction site tracks are saved as well as a list generated, printed out and saved with new TAN numbers, whereby the ESTW interface module those TAN numbers that happen to be too occur in the first construction site, not accepted. In a preferred one Embodiment are in addition to the number of the A cell phone Phone numbers of the B cell phones belonging to the A cell phone are stored, to enable a collective call.

If the construction site affects several, e.g. arranged one behind the other Track sections (e.g. moving construction site) or should be several construction sites Processed one after the other on different track sections separate TAN numbers for each section of track assigned and selected. The last TAN number of a track section then unlocks this section permanently. Are the works terminated at the relevant track section, the The site manager gives the dispatcher the last TAN number via radio. Instead of the last one, another TAN number of the TAN numbers assigned to the respective track section as a signal for Unblocking can be used.

The first TAN number of the next track section to be processed lock this before the track work in this section begins become. Before starting work, the site manager sends the Dispatcher the first TAN number via radio. Instead of the first can also another TAN number of the respective track section assigned TAN numbers can be used as a signal for blocking. The dispatcher transmits a receipt to the site manager via radio. The signal from the signal box confirms the effectiveness of the blocking and that there is no train in and in front of the blocked section.

Through this type of blocking and activation, the duration of the Closure minimized to the actual duration of the track work.

In the method according to the invention, the respective site manager must only once at the beginning of the construction work with the dispatcher agree, then all warning processes run automatically. In this In consultation, the site manager notifies the start of the construction work and the The dispatcher blocks the route. The time of blocking and Removal of the blockage can be described as for the hiking construction site be specified by the dispatcher via radio, even for one individual construction site. By a normal entry in the ESTW operator station 8 this route is blocked against traffic. In the ESTW this route can marked as blocked and provided with a notice and on the Operating monitor are displayed. The note is e.g. RO1 for rotting 1 and RO2 for Rotte 2, etc.

At the construction site there is the portable computer 11 with the A cell phone connected is. In the portable computer 11 are advantageously B cell phone numbers saved. The B cell phones can too Analog devices that are from the portable computer 11 and the A cell phone or can be selected directly from the ESTW interface module via collective call. Every construction worker on the track has a B cell phone, which he uses to clear the Construction site can be requested. The warning is given by a ringtone of the cell phone or when wearing hearing protection one in hearing protection built-in headphones connected to the cell phone or the Vibrator function of the cell phone.

If a train is now approaching the construction site, it will become one at a time the train more than its braking distance from that covering the construction site Main signal is removed, a warning from the ESTW interface module Form of a data telegram with the usual for signal technology Code security automatically generated and via the GSM module 6 to the A mobile phone of the site manager and the connected portable computer 11 transferred. For documentation purposes, this is done with the ESTW interface module connected printer with the time printed out. The Track workers receive a request via the B cell phones to close the track evacuate. Once the track has been cleared, the site manager sets one on the A-Handy corresponding message with the next TAN number from its TAN number list that reaches the ESTW interface module via GSM. The ESTW interface module compares the received TAN number with the expected TAN number and generated if they match automatically sends the ESTW command to unlock the track him to the ESTW operator station 8. If the cancellation is effective, a Route is placed over the signal covering the construction site. Will in ESTW interface module found that the train dissolved the route it automatically initiates a new blockage of this route the entry of the reason for blocking, e.g. RO 1. Is this blocking effective? and if the train has cleared the entire construction site area, the ESTW interface module a message to the A-cell phone together with transferred to the next TAN number that the construction site will enter again can be. The site manager compares the TAN number with his List and returns if the received matches the expected TAN number free entry to the track. The TAN number list can can also be stored in the portable computer 11. Then they will Compare with the TAN numbers and send out the TAN numbers automated. The portable computer 11 is e.g. programmed to be an incoming warning call with the stored TAN numbers compares and if there is a match, a collective call to all B cell phones sends. Likewise, an acknowledgment signal is sent automatically the corresponding TAN number is also sent. A cell phone and portable Computers 11 can also be integrated in one device, e.g. Nokia Communicator. Nokia Communicator and ESTW interface module have, for example, a common data interface, e.g. about Cable or infrared, through which the TAN numbers to the Nokia Communicator and / or the Nokia Communicator number ESTW interface module can be communicated.

The TAN numbers protect against unauthorized interference. Instead of Another security method can be used for TAN numbers e.g. a cryptic encryption via a so-called "Security Translator" for the transfer from and to the A-Handy. Instead of other numbers can be used from TAN numbers or codes, e.g. also letters or only letters or Contain special characters.

The ESTW interface module has security responsibility. It has to be everyone Recognize the train approaching the construction site and that covering the construction site Automatically block the signal or the affected track sections.

If the warning does not arrive at the construction site or the room message from the Do not rot at headquarters, e.g. in the event of network congestion, the train will move forward the construction site braked because the automatically inserted lock is effective remains.
