Definitions

  • the invention relates to a device for implementing a universal route safety technology by means of industrially available PLC components. It is used to adapt interlockings of any type with block devices that secure the block sections belonging to this interlocking free route to a new adjacent electronic interlocking.
  • rail vehicle operation can be centrally managed and secured by the interlocking systems responsible for the corresponding infrastructure areas and decentralized route safety systems.
  • an automation platform which comprises a plurality of modules, in particular CPU, power supply, module for safety-related signal processing, module for non-safety-related signal processing, communication module, connected via special interfaces with safety-related and non-safety-relevant components of the railway safety system.
  • the automation platform is a programmable logic controller (PLC).
  • PLC programmable logic controller
  • the predefined software structure of the automation platform is modular or hierarchical in that the logistics of the railway safety system, in particular the interlocking logistics, can be organized in function-specific software programs.
  • the EP 0 787 639 B1 describes a device for coupling an electronic interlocking to a relay interlocking.
  • the device is on relay interlocking limited and requires a sensor IS for measuring the loop current I. Based on the measured loop current are controlled by a processor MP, a variable impedance and a switch such that all states of the relay block to be replaced are adjustable.
  • the operation of the block logic is thus translated into another logic defined by variable impedance values and interpreted in the detour via a table to be evaluated by a microprocessor.
  • metrological components such as the current sensor and a transformation into its own logic unfavorably for the self-contained route safety technology a complete - and indeed new for both endpoints - total safety evidence must be performed.
  • the circuit of the coupling device EB behaves basically like a transmitter / receiver, ie as a link between a self-contained transmission system and adjacent block devices, the block-technical dependencies are essentially realized only in the adjacent new interlocking (ESTW).
  • ESTW adjacent new interlocking
  • the new construction projects for regional and long - distance networks at DB AG are concentrated on route networks with mechanical signal boxes, electromechanical signal boxes and relay interlockings.
  • a direct adaptation of a new type of interlocking to existing and to maintain track safety systems is usually difficult and expensive.
  • a renewal of interlocking technology therefore requires a costly adaptation of the existing interlocking or track safety to the respective new interlocking technology.
  • the current adaptations to existing route safety techniques are carried out via individual and company-specific technical solutions with the help of relay modules.
  • the project-specific conditions demand a high level of hardware and project planning, testing and downtime performance.
  • the previous use of basic circuits tried to counteract this, but leads in individual cases to very complex and therefore complex solutions.
  • the basic circuits take into account a wide range of applications, although only a fraction of the realizable by the basic circuit options is required in the project-specific case.
  • a matching circuit together with existing or new industrially available transmission technology, creates a universal interface via which arbitrary link block devices are adapted to new interlockings. From the existing block devices of an old signal box, the approved transmission modules can continue to be used. Only the relay circuits of the block groups which are relevant for the function of the block logic are replaced by a PLC system which exactly simulates the block logic and processes the electrical signals of the block logic in standardized form in such a way that the new interlocking can record and further process the specified data. Likewise, the device can record specified information of the new interlocking and process it in the block logic. For this purpose, the relay circuits of the block groups which are relevant for the function of the block logic are replaced, for example, by a ladder diagram with which the
  • PLC system is programmed so that it takes over the functions of the block logic.
  • the existing track-free signaling technology of the line safety device can, if required by the company, be left or replaced by axle counting technology.
  • the existing or new transmission technology ensures secure data transmission between the adjacent interlockings.
  • the PLC system may be placed at the location of the at least one new interlocking or at the location of the existing neighboring interlocking or in at least one decentralized switching house.
  • an advantageous embodiment of the invention is to build the PLC system by means of at least two diverse PLC controls, in each of which the block matching logic is implemented to the neighboring interlocking.
  • Both PLCs are programmed using the proprietary programming tools of the PLC manufacturers.
  • Each PLC checks the states determined by the block logic for plausibility.
  • the PLC system then compares the results and function of the two diverse PLC controls in a comparator. If there is a match, it is ensured that the signal from both PLC channels was formed without error. Thus, the data can be forwarded to the new interlocking for internal processing. If the data does not match, it can not be assumed that the system is working properly. The system recognizes this as an implausible state.
  • Claim 4 describes how status and diagnostic information is provided by the diagnostic unit to the non-secure diagnostics interface for maintenance / suppression.
  • the diagnostic interface supports the common serial interface types, such as RS 232 C, ETHERnet, fieldbuses (Profibus, CAN bus, etc.) as well as a bit-parallel interface.
  • the diagnostic unit provides all essential states of the block. In the event of a fault, targeted and rapid fault clearance is possible due to the displayed diagnostic information.
  • the self-block frame is replaced by a universal block interface (3, 4, 5, 6) with internal block logic (3), the device according to the invention being connected, on the one hand, to the existing transmission system (2) and, on the other hand, to the input and output modules (7 ) of the STW new (13).
  • the universal block interface takes on the side of STW-new all the tasks of the previous self-block technology.
  • the device according to the invention can be installed in the location of the STW-old or in the STW-new.
  • the exchange and processing of the block information between the device according to the invention and the new and old interlocking is shown below using the example of an exit from STW old (1) in the direction block with entry into STW new (13).
  • the functions permit release and "permission handles" are in the concrete example the possible block operations.
  • the block Before driving a train from left to right, ie from the area of the STW old in the direction of STW new, as a prerequisite must first be the permission on the side of the deflating neighboring station STW old (left), the block must be in basic position and allowed not be disturbed. The track section must be clear and the track vacancy notice must not be disturbed.
  • STW-old the following reactions and processes occur:
  • the extension train N1 at the neighboring STW-alt (STW-old) is set by the operator of the STW-old. If the block basic position is given and the permission exists in the STW old, a renewed permission change is first technically blocked and the successful basic position check is saved.
  • the block lock is now active and prevents further routes in the direction of the route.
  • the active block lock is indicated by the illuminated exit blocking detector.
  • the extension signal N1 may now show travel. The continuous monitoring of the track track approval and the permission becomes active in the STW old.
  • the train now leaves and occupies the last train detection section 1.4, then the extension signal N1 stops.
  • the associated track occupancy checker in the block group stores this information of the last station section until all the conditions of the block basic position have been met. Occupying the section N / P drop off the free fields of the route and the busy message of the route is turned on via the associated track occupancy tester and transmitted to STW new.
  • the corresponding block relays and the stop signal of the signal F drop off.
  • the following reactions and sequences occur:
  • the track occupied information sent by the neighbor STW-old is received and processed in the device according to the invention in such a way that the block segment detector in the STW red is switched on and the block alarm clock or the associated acoustic alarm is activated.
  • the hold notification information of the signal A is disabled in the block logic. This has the consequence that neither stop nor drive message are transmitted to STW-old.
  • the device according to the invention switches off the relevant track vacancy information in the block logic. With occupancy of section 1.2 drops the entry signal A in stop position, the device of the invention then switches off the state "driving message signal A" to STW old.
