Definitions
- the invention relates to a method for producing a Control signal, which is a track section of a track system as busy reports, with the process at each in the flow direction in the track section retracting drain unit an auxiliary signal is generated with a detection device and the control signal is formed with the respective auxiliary signal becomes.
- Such a method can be the magazine shunting technique and track connection technology ("Microcomputer - controlled electrodynamic directional track brake ", Jean-Pierre Pfander and Alexander Hörder, (1980/81), episode 40, Pages 45 to 47).
- Detector uses a contact, each in the Track section incoming running unit detected and a corresponding Auxiliary signal generated.
- a control signal that the Track section marked as busy is generated when the auxiliary signal is present.
- the previously known method can be For example, to use for the control of rail brakes, because in some types of rail brakes, such as. B. rubber rail brakes, the track brake must not be switched on, if a drain unit is in the track brake.
- the invention has for its object to provide a method for Generate a control signal to indicate, in which the control signal is generated when the track section of the respective Expiry unit occupied and probably not expected will leave more.
- the advantage of the method according to the invention is that when detecting the entry of a drain unit in the Track section is also determined whether the drain unit will stop in the track section; this will Concretely achieved in that the retraction speed of Sequence unit is measured and checked if this speed the drain unit is so large that the drain unit leave the track section again.
- Another advantage of the method according to the invention is in Its great reliability can be seen by the distance measuring device is achieved; with the distance measuring device namely, it is possible to detect whether obstacles are in the form of other drain units are on the track section, the a passage through the track section through the respective Aslaufisme would prevent.
- the method according to the invention can be used especially advantageous for controlling mounted in the track section Track brakes; because using the invention Procedure, the track brakes can already at Switching in a drain unit into the track section, when the drainage unit stops in the track section becomes. This timely shutdown of the track brakes is That's why it's so important, because it prevents it leaves that a drain unit in the switched rail brake stops and subsequently damages the track brake caused when the stalled drain unit - For example, by a locomotive - from the switched Rail brake is pulled off or pulled out.
- At least one track brake in the track section should be appropriate, considered beneficial if the Auxiliary value taking into account the braking characteristics of Track brake is determined because then even more accurate can calculate whether the respective drain unit in the track section will stop.
- Procedure can be achieved if the second threshold depending on the length of the respective drainage unit is determined; Specifically, the second threshold must be be sized at least so large that the respective drain unit between the end of the track section and the the next drain unit located on the track system is sufficient Takes place.
- FIG. 1 shows schematically an embodiment of an arrangement for carrying out the inventive method.
- the figure shows a track section 1 of a track system 3 with a weight-independent track brake 5.
- a speed measuring device 9 is mounted, are measured with the retraction speeds Vein each along an arrow 10 in the track section 1 retracting drain unit.
- the calibration factor k is in the range between 1 and 10 and, depending on the accuracy requirements, can also be dependent on the drain units or vehicle axles located in the track section 1. Very accurate measurement results can be obtained, for example, if the factor k is 2.5.
- a first intermediate signal S1 is formed. Instead, the first intermediate signal S1 may also be then formed when the retraction speed Vein or the extension speed Vout the first threshold below.
- Distanzmeß With a Distanzmeß driven 12 - as described for example in German Patent 31 27 672 - is measured to form a distance L, at which distance to Distanzmeß coupled 12 with respect to the respective drain unit seen in the drain direction next on the track system 3 located drain unit is located and a second intermediate signal S2 is generated when the distance measurement value L falls below a second threshold value.
- the second threshold value is determined as a function of the length La of the respective drainage unit, in such a way that the respective drainage unit finds sufficient space between the end X3 of the track section 1 and the next drainage unit located on the track installation; this is given if: (1) L - X3> La
- the second intermediate signal S2 is thus formed exactly when: (2) L ⁇ La + X3
- La + X3 thus represents the second in equation (2) Threshold.
- the length La of the respective drain unit can be known from expiration documents or measured in advance be.
- the second intermediate signal S2 may also be formed as follows, according to equation (2): (3) L ⁇ La + X3 + P, where P denotes an additional length, which may be several meters.
- the first intermediate signal S1 is from the speed measuring device 9 to an input E17a of a control unit 17 and the second intermediate signal S2 from the distance measuring device 12 to a further input E17b of the control unit 17th transfer.
- a control signal St generated when the first and the second intermediate signal S1 and S2 were generated.
