Definitions

  • the invention relates to several methods for increasing the Availability of decentralized axle counting and track vacancy detection systems according to the preamble of claims 1, 3, 4 and 5.
  • Axle counting and track vacancy detection systems are used to control the railway operation and must, especially with heavily frequented railway lines, very high reliability and availability requirements suffice. Safety and freedom from accidents of rail operations depends crucially on the flawless Function of the axle counting and track vacancy detection systems. In particular on free routes, at a greater distance from train stations, come decentralized, d. H. interlocking independent axle counting and track vacancy detection systems.
  • Metering point ZP1, ZP2, ZP3 Figure 1 preprocessing units VV ZP1, VV ZP2, VV ZP3 for signal processing of the Assigned counting results.
  • the preprocessing units implemented essentially in software VV ZP1, VV ZP2, VV ZP3 and the processing units VE A1, VE A2 to determine the occupancy status of the track vacancy detection section A1, A2 are on hardware components DZ1, DZ2, DZ3 implemented.
  • the listed faults and failures reduce availability of the system. It also eliminates the faults and failures in the known configuration performed by people whose error rate is known to be is significantly higher than that of electronic systems.
  • the invention has for its object the above Eliminate disadvantages and generic methods specify that allow at least part of the above to master malfunctions and failures listed in the table.
  • the redundancy is formed by forming additional, comprising several neighboring track vacancy sections, superordinate track vacancy sections produced.
  • a requirement-based specification is preferred of the superordinate track vacancy sections.
  • the formation of the higher-level Track vacancy sections on very different Way. For example, several points of delivery can be bridged or - if necessary, of the type depending on the fault - a fault or failure fault quasi different lengths of superordinate track vacancy sections To be defined.
  • Several superordinate ones can also be used Track vacancy sections nested one inside the other become. In this way, part of the interference and Bridge failures. The effect of this and others below for explanatory procedures regarding the various fault and failure constellations is in the tables shown below.
  • Another procedure characterized in claim 3 is based on redundancy through additional reference points of delivery and Track vacancy sections, while according to claim 4, several independent Processing units for determining the occupancy status the track vacancy detection sections are provided.
  • claims 5 sees the parallel application at least two of the three procedures outlined above in front.
  • the hardware components of the metering points are preferred for the software both from preprocessing units to Preparation of the counting results as well as processing units to determine the occupancy status of the track vacancy detection section used several times. In this way there is no need for additional hardware installations. Depending on the application however, it can also be useful for different To use subtasks separate hardware components reduce the risk of default.
  • FIG. 2 illustrates the formation of a redundant higher-level metering point section ÜA1.
  • the associated processing unit VE ÜA1 is implemented on the hardware platform DZ2 and processes the output data of the preprocessing units VV ZP1 and VV ZP3 of the metering points ZP1 and ZP3.
  • the table below summarizes the effects of the faults and failures described above. Controllable malfunctions and failures are highlighted in gray. Effect St1 VE A1 / VE A2 takes on the occupied state, since no ÜA's can be formed via limit points ZP1 / ZP3. St 2 The occupancy status of A1 / A2 can be determined correctly using the information from VE ÜA1.
  • VE A1 and VE A2 take the state freely.
  • St3 VE A1 / VE A2 takes on the status occupied because no limit points ZP1 / ZP3 can be used to form ÜA's.
  • St 4 Since the section VE ÜA1 is not occupied and no axes "fall from the sky", traffic can be excluded. Therefore, VE A1 and VE A2 take the state freely, boundary condition: suspension vehicles must be excluded or the amount of acceptable interference pulses must be suitable be restricted.
  • au1 VE A1 / VE A2 takes on the occupied state, since no ÜA's can be formed via limit points ZP1 / ZP3.
  • au2 The occupancy status of A1 / A2 can be determined correctly using the information from VE ÜA1.
  • Au3 VE A1 / VE A2 takes on the occupied state, since no ÜA's can be formed via limit points ZP1 / ZP3.
  • Au4 A1 and A2 occupancy status unknown.
  • the table shows that in particular faults and failures of the limit metering points ZP1 and ZP3 using the superordinate track vacancy detection section ÜA1 cannot be remedied because there are no higher-level counting points ZP1 and ZP2 Track vacancy detection sections can be formed.
  • St1 ZP1 The occupancy status of A1 can be determined correctly using the information from VE R1.
  • St1 ZP3 The occupancy status of A2 can be determined correctly using the information from VE R2.
  • St 2 VE A1 and VE A2 assume occupied state.
  • St3 The occupancy status of A1 / A2 can be determined correctly using the information from VE R1 / VE R2.
  • St 4 VE A1 and VE A2 are in occupied state.
  • au1 The occupancy status of A1 / A2 can be determined correctly using the information from VE R1 / VE R2.
  • au2 VE A1 / VE A2 take occupied condition.
  • Au3 A1 / A2 occupancy status unknown
  • Au4 A1 and A2 occupancy status unknown
  • the multiple redundancy VE ÜA1 can be set both on DZ1 and can also be used on DZ2.
  • Figure 4 is exemplary shows what such a configuration could look like.
  • the procedure can also be applied to limit metering points ZP1 and ZP3 apply so that all the above malfunctions and failures are manageable.
  • the parent Track vacancy detection section ÜA1 redundantly calculated on DZ1 and DZ2.
  • the point of delivery is ZP2 failed, so that a superordinate track vacancy section ÜA1 must be used to obtain information.
  • processing unit VE ÜA1 is on the hardware platform DZ2 not available. Thanks to the redundant design the processing unit VE ÜA1 on the hardware platform DZ1 this information can be used and thus the failure can be controlled.
  • the methods presented can be redundant and Combination can be suitably dimensioned. Because of the flexible The method can be combined with redundancies Install inexpensively.
  • the invention is not limited to the above Embodiment. Rather, there are a number of variations conceivable, which is also fundamentally different Execution make use of the features of the invention.
