Definitions
- the invention relates to a stepping device for a rail vehicle, comprising a stepping platform, a housing from which the stepping platform can be extended and retracted, and a control unit for controlling the extension and retraction movement of the stepping platform, with the stepping platform comprising a plurality of stepping contact segments that an application of pressure generate signals which are transmitted to the control unit.
- Mobile step platforms often called sliding steps, are known from the prior art. They have a safety mat for weight detection. This generally consists of two superimposed, homogeneous and electrically conductive contact surfaces that are encapsulated in a flexible compound. When the foot is stepped on, both contact surfaces have electrical contact with one another (cf. FIG. 1), which is recorded and processed by an electronic control unit. Due to the full-surface design of the contact surfaces over the entire tread surface of the platform, however, it is not possible to distinguish between a stepping load by a passenger and a stepping load from jammed objects, such as e.g. B. Stray split (cf. FIG. 2 and FIG. 3) can be distinguished.
- the electronic control unit detects a stepping load and thus also stops the exit or exit originally intended for the protection of the passenger. entry movement . This unintentionally reduces the functionality and availability of the stepping platform.
- EP 2 015 964 B1 now teaches a stepping platform with a stepping contact mat divided into a plurality of stepping contact segments.
- the stepping contact segments are grazing shaped and in the direction of movement of the stepping platform when exiting or retraction arranged one behind the other.
- the control unit is designed in such a way that the signals generated by step contact segments that are inside the housing are ignored or that the step contact segments that are inside the housing are ignored. In this way, malfunctions due to jammed objects can be avoided. However, this requires information about the position of the foot contact segments at any point in time during the exit or exit. Retraction movement of the stepping platform.
- the invention is based on the object of specifying a further simplified stepping platform.
- the step platform that can be extended and retracted occasionally also called a sliding step, comprises a plurality of step contact segments which, when pressure is applied, generate signals which are transmitted to the control unit.
- the stepping platform can have a stepping contact mat divided into a plurality of stepping contact segments.
- the individual stepping contact segments have predetermined distances greater than zero from one another, so that an object with a predetermined minimum contact area with the stepping platform has at least two immediately adjacent stepping contact segments can apply pressure.
- the tread contact segments are spaced apart from each other on the tread platform.
- the control unit is designed in such a way that an object relevant to the control of the extension and/or retraction movement of the step platform is only recognized on the step platform and the control unit then controls the extension and/or retraction movement, in particular a stop of the extension and/or retraction movement. or in particular the retraction movement of the stepping platform when signals are transmitted from two immediately adjacent stepping contact segments.
- the stepping platform in particular the stepping contact mat of the stepping platform, is designed in such a way that a signal representing an object relevant to the control of the extension and/or retracting movement of the stepping platform is only generated on the stepping platform and transmitted to the control unit, and the control unit then controls the extension and/or retraction movement, in particular causes a stop of the extension and/or in particular the retraction movement of the stepping platform when the object on the stepping platform applies pressure to two immediately adjacent stepping contact segments.
- each stepping contact segment subjected to pressure generates a signal which is received by the control unit.
- This recognizes an object on the step platform that is relevant for the control of the extension and/or retraction movement of the step platform only if the signals from two directly adjacent step contact segments have been received.
- a signal which represents an object relevant to the control of the extending and/or retracting movement of the stepping platform and which is received by the control unit is only generated if pressure is applied to two directly adjacent stepping contact segments.
- the stepping contact segments are designed in the form of strips and are arranged next to one another, parallel to the direction of the extension and retraction movement of the stepping platform.
- the contact segments can assume other flat, geometric shapes.
- Z. B. be circular or square.
- the stepping platform could have circular or square stepping contact segments distributed regularly over its surface.
- insensitive areas are arranged between the foot contact segments, with the areas of the foot contact segments being small compared to the areas of the insensitive areas in between.
- the non-sensitive areas between the foot contact segments are also strip-shaped.
- the foot contact segments are then designed to be correspondingly narrow in comparison to the insensitive areas.
- the stepping contact segments have the same distances from one another.
- the distances between two immediately adjacent tread contact segments are always the same.
- each specified distance greater than zero between two immediately adjacent stepping contact segments is at most 20 mm, in particular at most 15 mm, so that an object with a circular minimum contact area to the stepping platform with a diameter of 40 mm has at least two immediately adjacent ones Touches foot contact segments and can apply pressure.
- the stepping contact segments are at a distance of at least 10 mm, in particular at least 15 mm, from one another so that smaller objects cannot be recognized as relevant.
- the width of the stepping contact segments in the direction of the distance to the directly adjacent stepping contact segment, in particular perpendicular to the direction of the inward and outward movement of the stepping platform, can be further developed to be less than 10 mm, in particular less than 5 mm.
- the width of the foot contact segments is at least 1 mm, in particular at least 5 mm, at each point.
- the distance between the tread contact segments corresponds to the width of the insensitive areas in between.
- the width b of the surface of the foot contact segments is predetermined as a function of the width u of the insensitive area between the corresponding foot contact segments.
- all foot contact segments have the same shape and size and are at the same distance from one another. nander .
- the insensitive areas in between can have the same shape and size.
- the foot contact segments are designed such that they generate signals, which are transmitted to the control unit, only when they are subjected to a predetermined minimum pressure.
- the object In order to effect the signal-triggering pressure on two directly adjacent tread contact segments, the object must have a specified minimum weight.
- a further development of the invention provides that the stepping contact segments are spaced apart from one another in the direction and transverse to the direction of the inward and outward movement of the stepping platform, with non-sensitive areas in between, with the object having a predetermined minimum contact area with the stepping platform having a first stepping contact segment and at least a second step contact segment that is immediately adjacent and arranged at a distance transversely to the direction of the inward and outward movement of the step platform to the first step contact segment, and at least one step contact segment that is immediately adjacent to the first step contact segment and at a distance in the direction of the inward and outward movement of the step platform to the third step contact segment arranged in the first step contact segment with pressure.
- the stepping platform is then designed in such a way that a signal representing the relevant object, specified minimum contact area with the stepping platform, is only generated and transmitted to the control unit if the object on the stepping platform has the first stepping contact segment and the second stepping contact segment and the third stepping contact segment with pressure applied.
- each pressurized contact segment generates a signal and the control unit is designed in such a way that the relevant object with a predetermined minimum contact area is only recognized if signals from the first contact segment and the second contact segment and the third contact segment are transmitted to the control unit.
- a vehicle according to the invention in particular for passenger transport, in particular a rail vehicle, has at least one step device according to the invention.
- Fig. 1 shows the cross section through a step platform with a step contact mat of the prior art
- Fig. 2 shows a stepping device with small objects on its stepping platform
- Fig. 3 shows a cross section through the step device according to FIG. 2 .
- Fig. 4 schematically shows a stepping platform of a stepping device according to the invention
- Fig. 5 schematically shows the stepping platform from FIG. 4 with an object to be recognized as relevant for the control of the inward and outward movement
- Fig. 6 shows a further embodiment of a stepping platform according to the invention.
- Fig. 1 shows a conventional extendable step platform 1 with a step switch mat for weight detection.
- This has two superimposed, homogeneous and electrically conductive contact surfaces 5, 6, which have electrical contact with one another when a foot is stepped on, whereupon a signal is generated and transmitted to a control unit for controlling the extension and retraction movement of the foot platform 1.
- a jamming of the grit 7 when retracting the stepping platform 1 between of the stepping platform 1 and its housing 2 leads in the electronic control unit to a detection of stepping stress and thus also to the originally intended for the protection of the passenger stopping the exit or exit. entry movement .
- the entry direction is marked with an arrow.
- Fig. 4 shows a schematic three-dimensional representation of a mobile stepping platform according to the invention for a rail vehicle, which can be moved out of an associated housing and is equipped with a stepping contact mat divided into a plurality of stepping contact segments 3 which, when pressure is applied, generate signals which are fed into a control unit .
- the foot contact mat comprises two electrically conductive contact surfaces lying one on top of the other.
- the lower contact surface 6 is designed over the full area here.
- the upper contact surface 5, on the other hand, has a perforated grid-like structure.
- Insensitive areas 4 are arranged between strip-shaped stepping contact segments 3 arranged next to one another, which are aligned parallel to an extension and retraction direction of the stepping platform 1 and into the associated housing. If there are smaller interfering objects such as grit on the insensitive areas, no electrical contact is made between the contact surfaces 5 and 6 even if they are jammed between the step platform and the associated housing when the step platform is retracted into the housing, and therefore no signal is generated and sent to the hand over control unit .
- the distances between the step contact segments are dimensioned in such a way that an object with a specified minimum contact area with the step platform 1 has at least two immediately adjacent step contact segments 3 is pressurized and the stepping platform 1 is designed in such a way that a relevant object represent- of the signal is only generated and transmitted to the control unit if the object on the step platform 1 applies pressure to two immediately adjacent step contact segments 3, or the control unit is designed in such a way that a relevant object is only recognized if signals from two immediately adjacent step contact segments 3 be transmitted.
- the distance between two adjacent foot contact segments 3 and thus the width of the insensitive areas 4 between them is dimensioned such that each object with a minimum contact surface 8 to the foot platform with a diameter of 40 mm always touches at least two immediately adjacent foot contact segments 3 and applies pressure can, as shown in Fig. 5 outlines . Smaller objects, such as grit 7, can thus remain unconsidered.
- FIG. 6 Another embodiment is shown in FIG. 6 outlines .
- the foot contact segments 3 are designed as flat geometric figures, here as no rectangles.
- each step contact segment 3 also has a distance in the direction of the inward and outward movement of the step platform 1 to its immediate neighbor.
- a signal is only generated or the signals of the step contact segments are only recognized as relevant by the control unit if a first step contact segment 31 and its immediate neighbors 32 and 33 are subjected to pressure in the direction and transverse to the direction of the inward and outward movement of the step platform 1 will .
