DE102006052924A1 - Electrical location posed drive element controlling method for use in rail-bound traffic system, involves transferring adjusting command from personalized computer to servo computer for electrical location posed drive elements - Google Patents

Abstract

The method involves transmitting a functionally addressed call (9) by a global system for mobile communicationterminal (1), over a telecommunication network (2) for providing voice services to a personalized computer. Functional call addressing is selected from a link connection message without call acceptance, where an adjusting command is generated from the addressing. The adjusting command is transferred from the personalized computer to a servo computer for electrical location posed drive elements detected by the adjusting command. An independent claim is also included for a device for remotely controlling an electrical location posed drive element in a rail-bound traffic system.

Description

The The invention relates to a method for remote control of at least one electrically located infrastructure element in rail-bound Traffic systems by means of at least one mobile transmitting device and a control computer for controlling the at least one infrastructure element and a corresponding device.

Of the Use of electrically operated switches (= EOW) is in rail transport systems, which exclusively for shunting trips in freight traffic be used, widely used. With this technology is included Plants that do not have excessive demands in terms of performance a waiver of interlocking systems possible. Usually it is envisaged that the operators of the shunting on the tracks Vehicles in each case in the course of their Rangierfahrt lying ahead Track element (usually a switch) in own direction and in own Safety responsibility (correct point setting, profile freedom of the path to be traveled etc ...) operate. More complex installations (e.g. marshalling yards) enable even an independent one Setting longer Rangierstrassen, in the course of several switches or infrastructure elements, controlled by a single operator action of the moving personnel become.

The existing systems usually have impact buttons, which are operated by the staff as soon as the relevant track element to be asked. Likewise it is well-known, everywhere the clear one Reference between the control element and the thereby controlled Track element not clearly evident by visual inspection is (for example, when setting multiple driving lanes comprehensive routes), Operating panels or panels to apply. The strike buttons, Operator panels and control panels are with the driving element to be controlled hardwired. The solution Although it is widespread, it still has drawbacks. On the one hand, there is still civil engineering for laying the cable connection required between operator and track element. On the other hand the controls are arranged so that the staff can handle them can operate from the vehicle should (ie not: stop, dismount, operate, rise again ...). This is from time-economic establish advised, as in a local Operating area, if necessary, a plurality of such localized Fahrwegelemente can be present and thus for the shunting staff too big Time lost. But because the staff in terms of the most diverse vehicles Take positions (standing on the driver's cab, on running boards standing, walking on marginal roads next to the vehicle etc ....) were sometimes elaborate Installed devices that provide operation from the different positions enable.

To avoid these problems, solutions are known from the prior art, which are based on the use of mobile transmitting devices, which can be carried by the staff and operated independently of the position taken on the vehicle. In this way, so fixed installations should be saved. So revealed the DE 201 21 524 U1 a mobile transmitting device which transmits encoded infrared signals to a controller responsible for the control of the or the infrastructure elements for the transmission of a control command. However, it is considered to be disadvantageous that the driving personnel require the carrying of a proprietary device which is otherwise unusable (here: infrared transmitter). Furthermore, it has proven in the practical handling of the infrared transmitter as disadvantageous that they must be targeted by the operator to a receiver (which is not always easy to do) and also - like all optical devices - are sensitive to contamination.

The DE 195 08 731 A1 proposes the use of a mobile control unit - preferably a mobile telephone - before, by means of which a connection to a security element controlling the guideway element is first constructed and then sent via this connection established a command text to the security device. This command is mirrored by the safety device and - after another confirmation by the mobile control unit - checked for executability and executed with a positive result. An acknowledgment is sent back to the mobile control unit via the existing connection, and the existing connection is finally dismantled. This solution has the disadvantage that the mobile operating units must be suitable for generating a command text. Even if the DE 195 08 731 A1 for the command input proposes the keyboard of a mobile phone and the output of an acoustic acknowledgment signal, so it is necessary to implement such a system nevertheless the implementation of a special application software for generating or analyzing the data packets to be transmitted.

Similar Problems throw suggestions on, the driving of the infrastructure elements by means of trunked radio suggest. Also for this would require proprietary devices, which is procured by potential users of the infrastructure facilities and have to be kept which makes the use of these infrastructure systems more expensive and increasingly unattractive.

The invention is based on the object, a remote control of at least one electrically Positioned infrastructure element in rail-bound traffic systems by means of at least one mobile transmitting device and a control computer for Steue tion of at least one infrastructure element to provide, which compared to the known prior art makes lower demands on the technology of the mobile transmitting device.

These Task is in connection with the preamble of claim 1 according to the procedural shaping solved by the invention that of the at least one mobile transmitting device is a functional addressed call over one for Voice services suitable telecommunications network to a matching computer is sent in the matching computer, the functional call addressing the connection setup message without call acceptance read out and off This addressing a control command is generated as well as this Control command from the matching computer to the at least one, for the Positioning command detected route elements competent control computer transferred for execution becomes. In this way it is possible that a control command can be transmitted by means of a simple telephone call, without being proprietary Transfer data telegrams Need to become. This represents a departure from the previous proposals, which either special transmission media (Infrared etc ....) or a command transmission means to be transmitted Provide data packets. By integrating a generic remote control in the area Existing telephone networks can be based on any proprietary technical adaptation measures on the part of the system user or the user to be carried by the system user operating devices be waived. A commercial, for telephony suitable mobile terminal is sufficient. The invention can also without further adaptation measures in all common Telecommunications networks (GSM, GSM-R, ISDN, BASA network the tracks etc.). Usually is a connection from the sending HMI device via mobile communication to an adaptation computer with landline (usually ISDN -) connection provided. The adaptation computer works telecommunications technology as the main office. He receives the call directed to it and calculates from its call setup message the one desired by the sender Positioning command over a standard interface is passed to the setting computer. Usually are matching computer and control computer in a conventional manner wired connected.

In complement For this purpose, the inventive concept provides that in the control computer received control commands are checked for feasibility. Recognized as feasible Position commands are then executed by the control computer and an execution acknowledging Data element is transmitted back from the control computer to the matching computer. In this analogous manner are recognized as non-feasible control commands rejected by the setpoint computer and the impracticability indicating data element is from the control computer to the matching computer transferred back.

According to one meaningful embodiment is in the matching computer after receipt of the acknowledging or rejecting Data element, the acceptance of the mobile transmitting device incoming call triggered and a voice and / or text message about the successful execution or impracticability of the setting command to the mobile transmitting device.

It is provided in this context that the language and / or Text message using data transported in the data element Information elements is generated. Vocabulary and structure of Data element are designed so that the matching computer (to on the plant name itself) no location-specific information must be included and thus become a freely applicable module.

To For this step, all processes have expired, without accepting the incoming call from the mobile transmitter would have been. Only when the feedback arrives from the control computer is for the purpose of transmission of the to be controlled Fahrwegelement now assumed state ("control command executed" or "control command not executed ") the pending Reputation accepted and a corresponding linguistic or textual feedback returned to the operator requesting the control command.

It is when placing electrically localized infrastructure elements no safety-related application, as each to be driven Track element under constant observation and control of the Rangierfahrt leading Staff stands. Therefore, there are no further measures for the Case requires that a pending call of a mobile transmitting device in the meantime - i. before call acceptance by the conversion computer - is aborted. Usually is it functional and sufficient if a positioning command is still executed, even if the feedback should no longer come to the mobile transmitting device. However, it is free to the skilled person without inventive step, additional Provide procedural steps for error handling of such a case. For example, would be conceivable, the release for execution of the control command in the control computer depends on a successful one feedback to make to the mobile transmitting device.

A:

Ortsnetzeinwahl gemäß den international bzw. national gültigen Vorgaben (z.B. „+4989" für zu steuernde Anlagen im Bereich des Ortsnetzes „München")

B:

Anschlussnummer des für einen räumlich definierten Steuerungsbereiches zuständigen Anpassrechners (z.B. „13082586" für die Fahrwegelemente des Gleisanschlusses der „Firma Müller” in München)

C:

Funktionsdurchwahl, z.B.: „00xy": Stellen der Weiche mit Weichennummer „xy" „abxy": Stellen eines Fahrweges von der Weiche „ab" bis zur Weiche „xy"

It is particularly advantageous if the functional address of the call originating from the mobile transmitting device is encoded from information for the unambiguous identification of the at least one travel path element to be provided as well as information for the unique identification of the positioning command to be performed. In this way, unique call numbers can be generated by means of a catchy syntax. Thus, it makes sense to build the phone numbers according to a scheme of unique plant number and an extension to designate the desired positioning command ("function extension") Such a functionally addressed phone number, for example, could be structured as follows:
ABC

A:

Local area dial-in according to the international or nationally valid specifications (eg "+4989" for systems to be controlled in the area of the "Munich" local area network)

B:

Port number of the matching computer responsible for a spatially defined control area (eg "13082586" for the track elements of the track connection of the "Müller company" in Munich)

C:

Function extension, eg: "00xy": Setting the switch with switch number "xy""abxy": Setting a route from the switch "down" to the switch "xy"

• – Ansage aller bislang von der mobilen Sendeeinrichtung eingestellten Fahrwege
• – Selektives Auflösen eingestellter Fahrwege
• – Abfragen von Störungs- oder sonstigen Anlagenzuständen des Fahrwegelementes bzw. des zugehörigen Stellrechners
• – Abspeichern einer im Störungsfall selbständig anzuwählenden Rufnummer des Instandhaltungspersonals, etc ....

In the case of function selection, additional special numbers can be provided for realizing additional functions, such as:

• - Announcement of all hitherto set by the mobile transmitting device routes
• - Selective dissolution of set routes
• - Querying of fault or other system states of the track element or the associated control computer
• - Save a call number of the maintenance personnel to be dialed independently in the event of a fault, etc.

The The invention further provides that in the matching computer from the call setup information of incoming call from the mobile transmitter the identity of the calling Transmitter read and with a stored directory of identities the one to carry is compared by setting commands authorized transmitting devices. On this way, a user management can be implemented, which in a particularly simple manner a triggering of setting commands Prevents unauthorized persons. parking requirements Unauthorized callers will be rejected, if necessary with justification and lead not for generating a positioning command. Operations in a wrong Installation by authorized operators will be reduced.

The device-oriented expression of the inventive concept sees a device according to the preamble of claim 8, wherein a matching computer between calling mobile transmitting device and adjusting computer is connected, which via a Instance to mediate over for voice services suitable telecommunications network incoming calls, a command generator to convert the incoming call in the connection setup message Calls contained functional addressing in processable for the control computer Positioning commands as well as over Means of transmission has the control commands to the control computer.

Additionally sees The invention provides that the adaptation computer via a device for generating of voice and / or text messages transmitted between setting and matching computer Data elements as well as over a device for outputting these voice and / or text messages features.

According to one meaningful expression the invention features the adaptation calculator over a device for reading the identity of the calling mobile transmitting device from the connection setup message of the mobile transmitting device incoming call and matching that identity with one stored directory of identities of the implementation of Positioning commands authorized transmitting devices.

Of the Concept of the invention is visualized in the following figures. It demonstrate:

1 schematic overview of a working according to the inventive method system for controlling electrically localized points

2 Representation of the components and signal paths within a working according to the inventive process matching computer

The 1 shows a GSM-R terminal ( 1 ) using the existing mobile network ( 2 ) and the wireline telephone network ( 3 ) a call ( 9 ) to a matching computer ( 4 ). The adaptation computer is in turn for a data exchange ( 5 . 6 ) with a computer which is responsible for the control of a locally operated switch ( 7 ) designed. This data exchange can be wired or radio-based depending on local conditions. The matching computer provides within the fixed network ( 3 ) is a main point. The function extensions represent virtual extensions. From the signaling protocol of the end device ( 1 ) incoming call will be in the course of the call ( 9 ) read out and their function extension is analyzed. By means of a command generator ( 11 ) is a for the control or setting computer ( 7 ) machine-readable instruction code generated.

Of the leader one in the shunting area of the siding of the "company Müller "in" Munich "entering shunting calls on approach to the first turnout of this siding a phone number. This telephone number is uniquely assigned to this switch Plant number and a function extension for the determination of the Rangierer desired Action together. For the position of individual points is - in addition to that for the switch provided plant number - as a function extension e.g. entered the sequence of numbers 00. For the position of driveways on the other hand, after the plant number - the entered unique numbers of the start track and the destination track. For example, such a number format prevents the operator unintentionally puts only a single switch, although he actually wanted to provide a multi-element guideway.

For example addresses the telephone number "08912340104" to one in the local area network Munich (089) plant (plant number 1234) setting a driveway from track 01 to 04. The facility number can be simplified to a Fast memory key are stored, if the terminal controls this.

The ringing of the telephone (dial tone) indicates to the operator that the setting command for the called system has been received. The inventively executed system gives the control command to the control computer (or EOW computer) on and receives from this the message about the status of the execution of the control command (eg completed, not possible etc ...). The system executed according to the invention then accepts the "telephone conversation" and gives the user verbal feedback in which system the route has been set or is not possible in which system the linguistic feedback is transmitted by the message generator in accordance with the feedback from the EOU. Annex from a pre-configurable vocabulary ( 15 ) compiled. This vocabulary contains besides the message texts ( 15.2 ) always all element numbers (turnouts / tracks etc ...) ( 15.1 ). It makes sense to provide the numbers from 1 to (for example) 999, so that no system-dependent adjustments of the vocabulary are required. Only now there is a direct telephone connection between the operator and the matching computer.

Registration in the annex:

to Avoidance of incorrect operation by authorized operator (e.g. by voting and unintentional dialing a wrong system number) is a logon process in the system, within which the operator would like to address setting commands. To do this, first a call with a special feature number in this attachment placed (eg with the function extension "90"). The operator receives the feedback "in the Munich-Nord plant logged in "and is thus registered in this annex. At each following command is from a working according to the invention System tested, whether the respective operator is registered. Would like this another plant as the one in which he is logged in, he receives an error response ("Not logged in ") In this case he can then contact the right system.

To a certain amount of time without operator action - system-specific parametrizable - or after a special logoff operation, the operator is logged off.

This Procedure has an analogy to repetition in terms of asset selection on one-sided speech connections on.

Of the Advantage is that not by accidental adjustment of driveways the operation is hampered. But there is no effect to have security the logon function does not have to be secure either.

Querying and deleting set routes:

Around resulting from wrong or not driven routes, operational difficulties should be kept as low as possible Query possible be whether a track or which is set. By choosing one corresponding functional extension (e.g., "91"), the operator will be prompted as to the selected Plant number set routes announced.

In addition, it is possible in an analogous manner to delete routes of the plant concerned selectively. The track to be deleted must be identified. This could be done, for example, with the command syntax "999 - Start - Destination." Alternatively, however, you can also specify that in the function extension the element numbers are increased by a fixed amount - eg "+50" - a function extension "5162" would be describe the clearing of the track from track 01 to 12. After deleting, the operator receives feedback about the deletion. The coordination with other Rangierern in the plant, which could need the track, lies in this case Responsibility of the operator.

Exchange ( 12 ):

The Switchboard works like a telephone system that the incoming phone calls but not to individual devices forwarded, but the command generator reports which port or which extension was called. Furthermore Forwards the incoming call to the so-called "virtual telephone".

"Virtual telephone" ( 16 ):

The Virtual phone stands for the almost unlimited variety of phones used by the central office could be addressed. The virtual telephone forwards the caller's number to the user administration, and takes the call, to the voice messages of the message generator to the operator send.

User management ( 14 ):

The User administration receives from the virtual telephone the caller's number.

in the Following a call initiated by the caller receives the user management from the central office the "sign in" signal. It then checks to see if the user is entitled to do so. If so, he will be logged in. The user administration sends a signal to the message generator and wears the Number in a temporary Memory that is cleared after the set time.

In front every operating action checks the user administration, if the calling number is registered. is If so, it releases the lock. In addition, the login time set the number back to zero.

Lock ( 17 ):

The Lock prevents unintentional commands from the command generator be sent to the control computer. In the ground state is the lock activated, and can only be opened by the user management (see above). A manual key can be provided by means of which also this unlock function can be blocked. This button brings the plant in a configuration mode in which no issues take place at the control computer.

Command generator ( 11 ):

Of the Instruction generator converts the function selections in for the setpoint computer understandable Telegrams and sends them through the lock to the setting computer.

Message generator ( 13 ):

Of the Message generator receives from the user administration or the EOW the signals a voice message to create. He puts these from the different parts of the vocabulary together and send them to the virtual phone.

Vocabulary ( 15 ):

At the Vocabulary is a database of various, for Creation of voice messages more necessary Language files. additionally can For example, but also plain text name for the equipment stored become.

To Expiry of a configurable period of time without sending a positioning command a registered operator can be logged out by the system.

Control unit ( 18 ) and button ( 18.1 ):

By Actuate one by key secured button on the housing of the adjustment calculator, a control unit is activated. This will first the Lock enabled. Certain preconfigurable function numbers enable a direct forwarding from the central office to the controller so that for example, recorded plant name or set the time can be.

Signal flow at login:

Of the Incoming call is forwarded by the modem to the central office. This recognizes the login feature option and gives a signal to the User administration. At the same time the call to the virtual phone forwarded, which passes the caller number to the user management. The user administration receives So a phone number and the signal to log in. After testing, whether The caller is corrected, he will be for a certain period of time Registered.

thereupon the user administration sends a signal to the message generator which then the message "registered" or "not legitimizes "about that Virtual phone transmits to the operator. This transfer happens by the acceptance of the conversation through the virtual phone (until then the operator hears the "ringing" in the phone), first now the connection between the operator and the system became open. Subsequently puts the virtual phone on automatically, causing the connection is disconnected.

Signal flow at turnouts or driving points:

Incoming calls are received from the modem forwarded the exchange. This passes the function extension to the command generator, which generates from it, understandable for the control computer Stellbefehl which is sent via the lock to the control computer.

simultaneously the call goes to the virtual phone, which is the caller number to the user administration. If the caller is not logged in, the user management locks the lock, causing the command generator outgoing command is not forwarded to the setting computer. It can be configured that the lock on entering a positive or negative confirmation waited by the user management and then forwarded.

Either from the control computer (in case of operation) or from the user management (in case of rejection of the operation) a message goes to the message generator one. This generates a corresponding voice message and transmits it via the Virtual phone to the operator.

Of the Procedure when deleting and querying of roads is analogous to this.

For configuring a running according to the invention Systems are provided in different variants:

Configure by means of terminal:

To the Configure the matching calculator with the location-specific data is on the case attached to the matching computer key secured by a key. By pressing This button activates the lock so that it does not cause accidental operations comes.

After pressing a button incoming calls are then routed to the control unit, which forwards the new settings made to the appropriate memory. Depending on the number dialed, the operator can record the system name or set a maximum period for maintaining the "logged on" status despite the absence of operator actions. 15.1 ) the vocabulary and is thus available to the message generator. By means of appropriate function extensions, the "logoff time" can be set (eg by the function options "-991" to "-998" for 10 to 80 minutes, corresponding to the last digit).

Configure via USB plug:

The simple structure of the configuration makes it possible to store the corresponding data within a system operating according to the invention on a memory which can be accessed via a USB plug (eg by means of a laptop). All content can be stored in formats that can be edited with standard software:
".Txt" files: time setting, activation of caller numbers
".Waf" files: plant names, vocabulary (For applications in multilingual countries (Switzerland, Canada ...) this is particularly interesting because the reserve hardware has to be kept only once)

Of the Advantage of the configuration over USB is essentially in the adjustability of the approved Numbers. In the version without this setting option (such as the o.g. Configure by means of terminal) have to programmed the approved numbers during production become. Due to the adjustability of the allowed numbers of the Adaptation calculator completely configuration-free and universal.

The File contains two paragraphs. In the first registered numbers are entered and in the second the locked, of course, any not released Number is generally locked. For the meaningful use of this function need wildcards allows so that, for example, each number is subject to the scheme "030 297 ????" Approved can be. A "?" Stands for a digit / place a "*" could be for an unknown Number of digits / digits (for example 030 297 *)

Of the The paragraph for explicitly locking numbers is the same as above described to release certain number groups, but these in turn limit (For example, are all numbers released with 030 297 ????, then could simultaneously all numbers with 030 297 64 ?? be locked).

Of Further, the possibility be provided according to the information provided by the telecommunications system Number of digits to select different numbering codes.

For example:

• 4 digits,
• 6-digit with 3-digit element numbers and clearing of driveways by addition from 500,
• 6-digit with 2-digit element numbers and clearing of driveways by prefix from "99"
• or up to 9-digit numbered codes.

In the transition from the GSM-R to the BASA network, there is a call number restriction to 17 digits, so only 4 digits remain for the pure function extension. Therefore the coding "delete" must be solved with the help of the increase by 50. Within half of GSM-R these problems do not exist, Here a more comfortable and more universal coding can be selected.

These Function coding is only one way. There are others possibly more meaningful, more efficient in operation options conceivable.
