Definitions
- the length of the track sections Zvi ⁇ rule the track brakes a drainage system an essential input for a forecast of a time-distance line of ex ⁇ current units and ultimately is also the most efficient, yet reliable control of the entireméanläge.
- This object is achieved by a method for determining the length of at least one track section, where ⁇ caused by a driving of at least one track section with a plurality of rail vehicles, triggered by the respective track section limiting rail contacts Befahrungsmeldungen be detected and the length of the at least one track section is determined by a statistical evaluation taking into account the time intervals of the recorded traffic reports and axle distances of the rail vehicles.
- the inventive method makes it advantageously utilizes the fact that sections of track whose length during limited ⁇ men, are often limited in practice by loading rail contacts. It may, for example, those which are used for measurement of the speed or of the proving the property ⁇ standardized rail vehicles at respective rail contacts.
- any sensors which are suitable for the detection of individual wheels or axles of rail vehicles are referred to as rail contacts.
- the active principle it may be me ⁇ mechanically, hydraulically, pneumatically, magnetically, inductively or optically acting rail contacts here, for example.
- the respective track sections for each Rail contacts trip messages triggered, which are detected according to the first step of the method according to the invention.
- the Mög ⁇ friendliness that a separate Befahrungs- message is triggered and detected for each axis or each wheel of the rail vehicle.
- the part of the rail contacts Informa ⁇ tions collected with respect to multiple axes or wheels of the rail vehicle and a common Befahrung message is triggered for these axes or wheels. In the latter case, it will generally be necessary for an indication of the times of detection of the individual axles or wheels to be provided by the rail contacts with the respective warning message.
- the length of the at least one track section is determined by means of a statistical evaluation which takes into account the time intervals of the recorded traffic reports and axle spacings of the rail vehicles.
- the time interval of the detected Befahrung messages on the one hand, for example, thereby be determined that the part of the Befahrungsmel ⁇ applications receiving device, which may be, for example, a controller may be logged, the time points of the respective reception to passing over messages and used in sequence.
- the time interval of the detected traffic reports from information contained in the delivery messages itself, for example in the form of time stamps removed.
