Definitions
- the invention relates to a method for increasing the availability of a track vacancy detection system which is connected to an interlocking, wherein track vacancy detection sections are formed between axle counting points, and a related device.
- Axle counting and track vacancy detection systems are used to control railway operations and must meet very high reliability and availability requirements, especially on heavily frequented railway lines.
- the safety and freedom from accidents of railway operations depends crucially on the perfect functioning of the track vacancy detection systems.
- track vacancy detection sections are defined between neighboring axle counting points, the occupancy status of which is determined by comparing the counting results of the neighboring axle counting points.
- the main disadvantage of this standard configuration is the effects caused by faults and failures. Disturbances primarily include modifications of the signal curves caused by environmental influences.
- a failure is a permanent or intermittent malfunction of a functional unit, for example a signal connection. Failures and disruptions lead to operational disabilities. Particularly in the case of difficult-to-access track vacancy detection sections, for example in a tunnel, repairs can only be carried out at certain times, for example during the shutdown period.
- the invention is based on the object of specifying a method and a device of the above-mentioned type which enable an increase in the availability of the track vacancy detection system in a simple manner, in particular without expanding the interlocking interface.
- the object is achieved by the method according to claim 1.
- the object is also achieved by a device according to claim 5.
- the first and second track vacancy detection sections which are delimited by pairs of axle counting points, are either both in the free state or both in the occupied state.
- the determined statuses of the two track vacancy detection sections are processed in a third, virtual track vacancy detection section.
- This third track vacancy detection section behaves like a real, axle counting point limited track vacancy detection section in that the third track vacancy detection section only reports its own status to the signal box. On the signal box side, no difference is found between a real and a virtual track vacancy detection section. In this way, the interlocking interface can remain unchanged.
- the interlocking does not have to process two sections of information at the same time, namely that of the first track vacancy detection section and the second track vacancy detection section, in a complex manner. Also will Effort and costs are reduced, since the entire axle counting system no longer has to be duplicated, but only the axle counting points are required twice as axle counting point pairs.
- the table below illustrates the possible statuses of free, occupied, faulty and failure of the third track vacancy detection section depending on the statuses of free, occupied, faulty and failure of the first and second track vacancy detection sections as well as the resulting redundancy error messages.
- the third, virtual track vacancy detection section transmits its free status and the occupied status of the first or second track vacancy detection section to the Interlocking reports and the interlocking side a basic setting operation of the first or second in the occupied state Track vacancy detection section takes place.
- the functionality of the vacancy detection continues to exist when either the first track vacancy detection section or the second track vacancy detection section detects occupancy.
- This track vacancy detection section that has remained occupied is activated in the basic position. The availability is therefore not affected.
- the third, virtual track vacancy detection section reports its free status to the interlocking when the first or second track vacancy detection section is vacant and the other of these two track vacancy detection sections is occupied, and that the third track vacancy detection section switches the first or second track vacancy detection section that is in the occupied state to the basic position.
- the signal box then only receives exactly one track vacancy detection section status, namely the processed overall status of the third, virtual track vacancy detection section.
- the initial position of the real first or second track vacancy detection section that has remained in the occupied state is carried out by the third, virtual track vacancy detection section itself.
- the pairs of axle counting points are preferably each arranged in the same railroad tie compartment.
- the individual axle counting points, which form a pair of axle counting points, are arranged exactly opposite one another within the sleeper compartment in such a way that the track vacancy detection section lengths and boundaries of the first and second track vacancy detection sections match exactly. This ensures that when the axle counting points work correctly, both track vacancy detection sections either have the status free or the status occupied to the section computer of the third track vacancy detection section.
- the two axle counting points of the axle counting point pair have diverse hardware and/or software.
- the components used for wheel detection, namely the axle counting points, can be of very different types, but for the sake of simplicity they can also be identical.
- one of the axle counting point pairs delimiting the first and the second track vacancy detection section is designed as a single axle counting point with a dual-use function. This means that there is only one axle counting evaluation unit in a siding housing. However, a failure of this evaluation unit is so improbable that the availability of the overall system is only very slightly restricted as a result.
- the invention is explained in more detail below using a figurative representation.
- the figure shows the essential components of a device for increasing the availability of a track vacancy detection system.
- a first track vacancy detection section 1a is formed by two counting points 2a and 3a.
- a second track vacancy detection section 1b is delimited by axle counting points 2b and 3b, with the two track vacancy detection sections 1a and 1b exactly matching in terms of length and limitation.
- the axle counting points 2a and 2b as well as 3a and 3b each form axle counting point pairs 2a/2b and 3a/3b, which are arranged in the same sleeper compartment 4a or 4b of a track 5.
- An evaluation unit 6a determines from the axle counting results of the axle counting points 2a and 3a the status free, occupied, disturbed or failure of the first track vacancy reporting section 1a.
- a second evaluation unit processes in the same way 6b the counting results of the axle counting points 2b and 3b.
- the status information from the two evaluation units 6a and 6b is fed to an axle counting computer 7, which processes this status information.
- the processed status information is forwarded to an interlocking 8 as the status of a third, virtual track vacancy detection section.
- the interlocking 8 thus only receives status information of the usual type. Consequently, the interface to the signal box 8 does not have to be redesigned for double status reports.
- a status report from the axle counting computer 7 with regard to the third, virtual track vacancy detection section is uncritical as long as none of the real track vacancy detection sections 1a or 1b has the status faulty or failure. Then it is assumed that redundancy is present. This also applies if one of the two track vacancy detection sections 1a or 1b is reported as vacant and the other track vacancy detection section 1b or 1a is reported as occupied.
- the processing by the axle counting computer 7 leads to the free status message to the interlocking 8 and to the basic setting operation of the occupied track free reporting section 1a or 1b.
- the basic operation is usually carried out at the interlocking. However, it is also possible to relocate this functionality to the axle counting computer 7 external to the interlocking.
