Definitions

  • the invention relates to a method according to the preamble of claim 1. Such a method is known from EP 0 076 672 B1.
  • the object of the invention is a method according to the preamble of claim 1 specify that a local closure of the control elements in the vehicle, without additional sensors or Similar things become necessary and without additional communication costs for closing and dissolving the individual control elements are required.
  • the invention solves this problem by the features of the claim 1. Then check the control elements with the help of a changeable token known to them of a vehicle to unlock the lock, lead if necessary the pending actuating job and close the actuating element again.
  • the token can be in the control element or in the headquarters are generated.
  • Claim 2 relates to the token generation in one Actuator, the actuator after the treatise generates a new token for each job and to the control center via the vehicle that unlocks the lock transmitted.
  • the actuator generates from case to case Fall a token that is different from the one previously used Token. This prevents unauthorized vehicles from their knowledge of tokens previously assigned to them without authorization on the control elements of a guideway area to which they have no access authorization have.
  • One when or after executing a job from one Actuator generated for a subsequent actuating job valid token is from the still authorized vehicle according to the teaching of claim 3 when clearing the route section, which contains the control element for which the token applies to the head office.
  • This method ensures that a new token is not sent to a subsequent one Vehicle can be transmitted as long as by assigned the current token to a vehicle in front Track area is still traversed by this.
  • the token generation takes place in the headquarters instead and the control center informs the control elements the token that applies to your next claim.
  • Claim 5 provides for the generation of different tokens the head office, whereby the head office specifies two tokens, one of which concerns the current trip and the other others a trip to be made later.
  • the control elements initially only know about the nature of the token for the current trip and they take over the other Tokens from the vehicle authorized to access them, save it and use it to check the access authorization of a later vehicle.
  • This The type of expression of the method according to the invention has the Advantage that none on the spatially distributed control elements Means to generate tokens are required.
  • the tokens can advantageously be encrypted according to claim 7 and for recognition in the control elements again be decrypted. This is intended to prevent the token from being misused be protected by unauthorized third parties.
  • FIG 1 shows the interaction of a control center Z with a as a switch W trained actuator with the participation of a first vehicle F1 and a second vehicle F2, wherein the switch W den for a subsequent journey (vehicle F2) applicable token (Tb).
  • the vehicles are individual vehicles or vehicle associations.
  • Twa is deposited, which serves the one Access to the turnout W requesting vehicle F1 access to allow the switch when this vehicle is in possession of the valid token Ta.
  • the at the switch W stored token Twa can be assigned to the turnout, output token stored there in a memory, the when starting up z. B. by the head office from the Memory or has otherwise been activated.
  • the switch itself or on a corresponding promotion to the deposited token Twa corresponding token messages Ta to the The central office transmits this token to the first on the Assigns soft advancing vehicle.
  • This about the current one Token Ta informed vehicle F1 sits on approach to the switch via radio and communicates with it an order in cooperation with the applicable token Ta to release the lock on the switch.
  • the switch compares the token Ta transmitted by the vehicle F1 with the Token Twa deposited with him. Both tokens vote as expected in terms of content, the switch accepts the order to release the lock, releases the lock and leads the job order; then she puts the lock again and sets a corresponding status message to the approaching vehicle F1.
  • This status message includes in addition to the lock message for the switch W also a new one Token Tb, which should apply to the subsequent journey.
  • the switch W stores a token Twb corresponding to the new token Tb in their store.
  • the content of the new token Tb differs from the token Ta of the one currently accessing the switch Vehicle F1. It is preferably used under the switch Involvement of a random generator or a counter either newly formed or from a store for a variety retrieved from different tokens.
  • the approaching Vehicle F1 accepts the lock message along with the new token Tb and continues its journey towards the switch and beyond the turnout W.
  • the turnout W or a given turnout W contains the travel path area the vehicle F1 the new token Tb to the central office Z and thus puts it in Knowledge of the following recognized by the switch W. Token.
  • the complete passing of the turnout W or the free movement a predetermined route is from the vehicle F1 found that this z. B. with a track side cooperates or the location of his End of train determined automatically.
  • the turnout W lifts its lock opens, executes the actuating job and resets the lock forth. Then it transmits a corresponding status message with the assignment of a valid for the subsequent journey Tokens to the accessing vehicle holding this new token transmitted to the headquarters at the appropriate time.
  • the switch W is the current token Twa deposited, for example by a corresponding signal from the head office or from a predecessor vehicle.
  • the switch W compares the transmitted to it if applicable, decrypted current token Ta with the at your deposited token Twa, resolves if the contents match both tokens lock and perform the command out. Then the switch deposits the second one transmitted by the vehicle but not yet recognized by her Token Tb as new turnout-specific token Tbw in their memory and indicates a corresponding status message the switch F1 vehicle. This status message contains the current lock message of the turnout.
  • the vehicle for its part, teaches the head office on vacant reporting the switch W or a track area containing the switch W. from the fact that the switch W is assigned to the next trip Has accepted Token Tb.
  • the control center transmits this Vehicle next to the then current token Tb also the token Tc for the next trip. Procured with the current token Tb the vehicle F2 accesses the switch W and sets the associated job according to the desired turnout to the turnout W. The vehicle also transmits F3 of the switch assigned by the central station Z to the following journey Token Tc. The switch compares the transmitted current token Tb with the one from the previous trip you deposited token Twb and accepted the content of matching token the pending job. After the lock is released, the requested one Acting job executed and the two compared Token Tb and Twb are deleted.
  • Token also submitted Tc as a new turnout-specific Token Twc saved at the turnout.
  • the switch gives way the execution of the actuating job a corresponding lock message along with the recognition of the next one for the following journey valid token Tc to the to place the Deviate authorized vehicle F2. This teaches at Free the switch the control center that the switch the Has accepted Token Tc.
  • the head office directs a follow-up vehicle F3 assign this token Tc as the current token that the Vehicle is able to access the switch W and informs it the vehicle over that applicable for the subsequent journey Token Td.
  • This token is stored by the switch and serves the access authorization at a later time of a vehicle that then follows.
  • both of the proposed procedures are implemented with token generation on the control element and central token generation extraordinarily robust against the impermissible Access by a vehicle that is not authorized to access an actuator.
  • This robustness is due to the use differently designed tokens for the individual route assignments and the additional encryption / decryption the token reached.
  • the tokens can be as shown in the Embodiment individual control elements such as Switches, track barriers or level crossings are assigned, or even larger guideway areas with several control elements.
  • the decentralized solution individual control elements of a guideway area preferably assign different tokens, while at central solution to all control elements of the relevant route area the same token is assigned can.
