Description

The present invention relates to a traffic monitoring arrangement according to the preamble of claim 1.

For the purposes of traffic monitoring - for example speed control, traffic density measurement, toll control, etc. - traffic monitoring arrangements are known according to the preamble of claim 1, the at least one traffic monitoring device - for example a vehicle speed measuring device, an image recording device, a vehicle detection and counting device, a vehicle contour detection device, a vehicle -to-infrastructure communication device etc. - include such that such a traffic monitoring device for protection against weather influences is arranged, in particular fastened, in the interior of a housing of the traffic monitoring arrangements.
To establish the housing in the street-side floor, the traffic monitoring arrangement generally comprises a foundation, for example a concrete foundation, which can be designed as a precast concrete part.
In the case of the present invention, said housing is composed of a plurality of housing components which are arranged one above the other, for example, along a vertical axis opening into the foundation. The invention relates to housings with two or more (for example up to twenty) such housing components, the number of housing components being able to correlate with the number of different traffic monitoring devices which can be included in the traffic monitoring arrangement without restricting the generality in such a way that in each or one of the traffic monitoring devices is arranged in the majority of the housing component. In particular, the housing components are non-positively connected to one another, for example by means of screw connections.
The housing components can have a circular cross section, a rectangular or hexagonal cross section perpendicular to the vertical axis. In this respect, the housing components can be designed as hollow cylinders, hollow cuboids or hollow prisms with preferably open top and bottom surfaces at least in sections, the openings of which allow the inclusion of components extending over several housing components (e.g. power supply and / or signal lines and connecting means).
As a rule, the housing is fastened to the foundation, specifically by attaching a lower one of the housing components either directly to the foundation or via an intermediate piece through which the lower housing component - in particular along the vertical axis - is indirectly spaced from the foundation on the Foundation is attached.

For such traffic monitoring arrangements there is the problem that when a vehicle collides with the housing, the connections between the housing components yield, in particular break, with the effect that the housing at least partially disintegrates into housing components or individual groups of housing components that are still connected to one another. Such decay cannot be predicted uniformly because it depends on a large number of conditions, for example: the type of vehicle (car, truck), the speed of the vehicle, the impact angle of the vehicle, etc. This can result in generally unknown conditions In the event of an accident, individual housing components emerge from the housing assembly in an uncontrolled manner and cause additional damage, especially to uninvolved third parties.

From the published application EP 2 735 652 A1 a hollow mast with a predetermined breaking point and a flexible stop means is known, which connects a first local connecting area of the mast with a second local connecting area of the mast, the predetermined breaking point with respect to the second local connecting area to which the flexible lifting means is attached, on one of the first local connection area facing side of the mast is localized.
From the published application EP 2 918 750 A1 a traffic monitoring device with a two-part hollow mast is known, to which a camera is attached and which provides a predetermined breaking point with the connection point between a first mast part and a second mast part.

From the patent US 2,945,659 A parking meter column with a first housing component and a second housing component is known, which are connected to one another by a flexible stop means, wherein the connection point between the first and the second housing component provides a predetermined breaking point that relates to a local connection area provided by the second housing component which is attached to the flexible stop means is located on a side of the parking meter column facing the first housing component.

From the published application WO 2013 132 026 A1 is known a hinge device for holding a shield post or the like, which has a first link for connection to a substructure for the shield post, a second link for connection to a base section of the shield post and an articulated connection which is designed as a chain, and the first link with the second Link connects, wherein the joint device has a predetermined breaking point, which is provided on or in an intermediate piece, which is arranged between the first link and the substructure for the shield post.

From the patent EP-A-2 818 922 a traffic monitoring arrangement is known. The object of the invention is to provide a traffic monitoring arrangement in which an uncontrolled disintegration of the housing in the event of an impact is excluded or at least the probability of an uncontrolled disintegration is significantly reduced.

This object is solved by the characterizing part of claim 1. Advantageous further developments are the subject of the dependent claims. Features and advantages of various embodiments apply to the other embodiment in each case, transferable or interchangeable, insofar as this is technically and without contradiction possible.

The traffic monitoring arrangement according to the invention is characterized in that the first housing component and the second housing component are connected to one another by at least one flexible attachment means and the traffic monitoring arrangement has a predetermined breaking point, which has a local connection area provided by the second housing component and to which the flexible attachment means is attached a side of the traffic monitoring arrangement facing away from the first housing component is located.

This means in particular that the predetermined breaking point is located in an area of the traffic monitoring arrangement which is arranged on a side of the local connection area facing away from the first housing component.

Even if the term sling derives from the field of conveyor and lifting technology and characterizes a connection between suspension and load or load suspension equipment, this term was chosen for the static arrangement of the sling in the traffic monitoring system in order to be independent of the use that the concept of the sling means suggests defining the type of means which is used in the invention and serves the purpose of securely connecting the first housing component to the second housing component.
Nevertheless, an analogy with the conveying and lifting technology can be seen in the invention - and this analogy also justifies the use of the term sling: In the event of an impact, which would result in the housing being sheared off, in particular from a foundation area of the traffic monitoring device, which is intended to be arranged in the ground is, at the predetermined breaking point and a breaking of screw connections between immediately adjacent housing components of the housing entails, the lifting means ensures the cohesion of the first and second housing components, which were arranged one above the other before the impact, in particular along a vertical axis leading into the foundation area. A pulling force that is typical for conveying and lifting acts on the lifting means essentially in the direction of the gravitational force. In this sense, if the housing is aligned accordingly after shearing off the foundation area, that first or second housing component that is furthest away from the ground can act as a suspension element and that second or first housing component that is closest to the ground can act as a load.

With the invention, it is advantageously possible to reduce or even prevent damage that can occur as a result of a vehicle colliding with a traffic monitoring arrangement:
On the one hand, the predetermined breaking point in the event of an impact causes a defined shearing off of the housing or a main part of the housing, which comprises at least one traffic monitoring device, in particular from a foundation area of the traffic monitoring arrangement, which limits deformation of the accident vehicle.
A foundation area arranged in the ground (e.g. a foundation or a foundation section of the housing) of the traffic monitoring arrangement according to the invention cannot yield to an impact-related compressive force, as a result of which a shear stress is formed between the impact area and the foundation area, which leads to a break in the predetermined breaking point.
For this purpose, the predetermined breaking point can be designed in such a way that, due to the structure, it concentrates the shear stresses that occur and / or, due to the material, acts as a shear area due to a locally reduced shear strength.

On the other hand, the flexible stop means holds the first and second housing components together and protects bystanders from housing components and / or their contents that break out in an uncontrolled manner. Since the flexible sling is attached to the predetermined breaking point on a side of the housing facing away from the foundation.
It is advantageously ensured that the component that prevents the uncontrolled separation of the housing components does not suppress the desired shearing of the housing from the foundation area.

The traffic monitoring arrangement according to the invention preferably has a foundation area for establishing the traffic monitoring arrangement in the ground, the foundation area being arranged on a side facing away from the local connection area with respect to the predetermined breaking point.

For example, this foundation area is provided by at least one foundation for the foundation of the housing in the floor, in particular in the street-side floor.
The housing itself is less preferably provided for foundation in the floor, a foundation section of the housing with the exception of at least the first housing component being provided for arrangement in the floor and the predetermined breaking point also not being provided for arrangement in the floor.
For example, the housing has at least one foundation component, which is arranged on a side of the second housing component facing away from the first housing component, preferably fastened to the second housing component, and is provided for arrangement in the floor, the predetermined breaking point being arranged by the second housing component or in a region of the foundation component which is not intended to be arranged in the floor.

In particular, the traffic monitoring arrangement according to the invention has at least one traffic monitoring device, the housing according to the invention being designed to accommodate the at least one traffic monitoring device in the housing, in particular in an interior of the housing, in particular outside the previously mentioned foundation area.
According to the preamble of claim 1, at least one traffic monitoring device is comprised of the first housing component, the second housing component or an intermediate housing component of the housing, which is arranged between the first housing component and the second housing component.
Examples of traffic monitoring devices that are comprised by the first housing component, by the second housing component and / or by one or more intermediate housing component (s) of the housing, which are arranged between the first housing component and the second housing component, are one Vehicle speed measuring device, an image recording device, a vehicle detection and counting device, a vehicle contour detection device, a vehicle-to-infrastructure communication device. In particular, the first housing component and the second housing component belong to housing components of the housing which are arranged one above the other on a common vertical axis of the housing. In particular, this vertical axis opens into a foundation area of the traffic monitoring arrangement, for example a foundation of the traffic monitoring arrangement.
Such an arrangement of the first housing component and the second housing component is to be preferred for reasons of production, space and stability, but is nevertheless not mandatory. Thus, a third and / or fourth housing component of the housing can be arranged on the vertical axis of the traffic monitoring instead of the first and / or second housing component. Furthermore, a vertical axis common to the first and second housing components does not have to open into a founding area of the traffic monitoring arrangement, because this can be located outside the vertical axis.

The local connection area is preferably spaced from said foundation area in the direction of said vertical axis by the at least one predetermined breaking point.

In particular, the first housing component and the second housing component at least partially enclose at least one interior of the housing.
In particular, the first housing component is arranged with respect to the second housing component on a side of the second housing component that faces away from a foundation region of the traffic monitoring arrangement (for example a foundation).
The traffic monitoring arrangement preferably has a foundation and the housing has a lower housing component which is attached directly to a foundation component of the traffic monitoring arrangement (for example a foundation of the traffic monitoring arrangement or a foundation component of the housing).
Alternatively, the traffic monitoring arrangement has at least one intermediate piece, which is arranged on a side of the second housing component facing away from the first housing component, is preferably attached to the second housing component and can, but need not, be a housing component of the housing. In this case, a lower housing component of the housing can be attached to the foundation component at a spacing indirectly from the foundation component of the traffic monitoring arrangement by the intermediate piece.

In particular, the second connection area from a foundation area is the
Traffic monitoring arrangement which is provided for foundation in the ground (foundation section or foundation component of the housing or foundation of the traffic monitoring arrangement), through which at least one predetermined breaking point is spaced apart. In particular, the second connection area is spaced from the foundation area in the direction of a vertical axis opening into the foundation area, on which the first housing component and the second housing component are arranged, through the at least one predetermined breaking point.
If the traffic monitoring arrangement has said intermediate piece, the predetermined breaking point is preferably provided by this intermediate piece.
Regardless of the existence of said intermediate piece, the predetermined breaking point can instead be provided by a predetermined breaking area of the second housing component, such a predetermined breaking area being arranged between the second connection area and a fastening area of the second housing component fastened to the foundation.

Embodiments of the traffic monitoring arrangement provide a foundation area for the foundation of the traffic monitoring arrangement in the ground, the foundation area being provided by a foundation component which is designed as the foundation of the traffic monitoring arrangement or a foundation component of the housing, the first housing component and the second housing component count among housing components of the housing which are arranged one above the other on a common vertical axis of the housing opening into the foundation component, the first housing component is arranged with respect to the second housing component on the side of the second housing component facing away from the foundation component, the second housing component is directly or indirectly - that is: spaced from the foundation component by at least an intermediate piece - is attached to the foundation component, and the local connection area from the foundation component in the direction of the vertical axis through the at least one sol l breaking point is spaced, the predetermined breaking point being provided by the intermediate piece or a predetermined breaking area of the second housing component, which predetermined breaking area is arranged between the local connection area and a fastening area of the second housing component fastened to the foundation component.

In particular, the invention provides a traffic monitoring arrangement with at least one traffic monitoring device, at least one housing for receiving the at least one traffic monitoring device in the housing and at least one foundation for establishing the housing in the ground, the housing having a plurality of housing components arranged one above the other along a vertical axis opening into the foundation which enclose at least sections of at least one interior of the housing and a lower one of the housing components is attached to the foundation directly or indirectly - that is, spaced from the foundation by at least one intermediate piece - the traffic monitoring arrangement being characterized by at least one flexible attachment means with a first Connection section which is fastened via at least one first connection point to a first connection area of a first of the housing components and at least one second connection Section, which is fastened via at least one second connection point to a second connection area of a second of the housing components, the first housing component being arranged on the side of the second housing component facing away from the foundation, and the second connection area from the foundation in the direction of the vertical axis at least one predetermined breaking point is spaced, the predetermined breaking point being provided by the intermediate piece or a predetermined breaking area of the second housing component, which predetermined breaking area is arranged between the second connection area and a fastening area of the second housing component fastened to the foundation.

Said intermediate piece, which can serve as a predetermined breaking point, does not necessarily have to be a housing component of the housing. It can provide an interior space that is separate from the interior space of the housing that is provided jointly by the first housing component and the second housing component, or can be designed entirely without an interior space. It can also be formed by a porous structure with a large number of cavities. Alternatively, the intermediate piece can provide part of the interior of the housing, which is also partially provided by the first housing component and the second housing component. The intermediate piece can thus be understood as part of the housing.

The flexible lifting means according to the invention is understood in particular to mean a lifting means of structure-related flexibility. Such structure-related flexibility is provided in particular by a plurality of components (for example fibers, links, see below) of the attachment means that form the structure of the attachment means, which are connected to one another in a form-fitting manner in a manner that ensures the flexibility of the attachment means.
In this sense, for example, a textile sling is a flexible sling.
Exemplary representatives of flexible slings are a cordage, a chain and a webbing. In this context, a cordage is understood in particular to mean a flexible, elongated attachment means of essentially round cross section, in particular a wire rope or a braided line, produced by twisting or intertwining several elongate fibers, threads or yarns, etc. A chain is, for example, a series of movable, interlinked or articulated links. A webbing is, for example, a flexible, elongated attachment means of essentially rectangular cross-sections, produced by weaving fibers and / or wires. A belt webbing - with or without winding around the longitudinal axis - can be developed into a loop by ring closure.

In particular, the flexible stop means has a first connection section which is fastened to a first connection area of the first housing component via at least one first connection point, and at least a second connection section which is fastened to the local connection area as the second connection area of the second housing part connection via at least a second connection point .

The second connecting section is preferably arranged at least in sections in the second housing component or outside the second housing component in an alignment of the second housing component, which extends from the second housing component perpendicular to the vertical axis.
However, other arrangements are also possible in which the said first and / or second connection sections are each arranged so far from the first and / or second connection area that such a specific arrangement is no longer present.

The flexible stop means preferably has at least one first coupling section, via which the first connecting section is coupled to the second connecting section.
A longitudinal axis of the first coupling section is preferably oriented at least in sections parallel to the vertical axis. Although this saves material and space in the sense of the shortest bridging from the first to the second connecting section, it is nevertheless not essential. Alternatively or cumulatively, for example, the first coupling section can, at least in sections, spirally on cylindrical inner or outer walls of the housing components, In particular, intermediate housing components arranged between the first and second housing components run concentrically to the vertical axis.

The housing preferably has at least one intermediate housing component, which is arranged on the vertical axis between the first housing component and the second housing component, comprises at least one traffic monitoring device and via which the first housing component is connected to the second housing component, the first coupling section at least in sections in the intermediate housing component or outside of the intermediate housing component is arranged in alignment of the intermediate housing component, which extends from the intermediate housing component perpendicular to the vertical axis.

The flexible stop means is preferably arranged at least in sections in the intermediate housing component or outside the intermediate housing component in an alignment of the intermediate housing component which extends from the intermediate housing component perpendicular to the vertical axis.
The intermediate housing component preferably comprises at least one traffic monitoring device.

The first connection point is preferably designed as a first coupling which is provided by a first coupling section of the first housing component or by a first coupling component which is produced independently of the first housing component and which is fastened to the first housing component, in particular in a releasable manner. In particular, such a first coupling section forms a material unit with the first connection area of the first housing component. In particular, at least one fastening means for releasably fastening such a first coupling component on the first housing component engages in the first connection region of the first housing component. With such a design of the first connection point, a connection between the first connection section and the first connection area can be established in a simple and secure manner, the first connection section preferably being latched into a first coupling element, into which the first coupling is also latched. For example, such a first coupling element is a carabiner or a shackle.

Alternatively or cumulatively, the second connection point is preferably designed as a coupling which is provided by a coupling section of the second housing component or by a coupling component which is produced independently of the second housing component and is fastened to the second housing component, in particular in a releasable manner. In particular, such a second coupling section forms a material unit with the second connection area of the second housing component. In particular, at least one fastening means for releasably fastening such a second coupling component to the second housing component engages in the second connection region of the second housing component.
With such a configuration of the second connection point, a connection between the second connection section and the second connection area can be established in a simple and secure manner, the second

Connection section is preferably latched into a second coupling element, in which the second clutch is also latched. For example, such a second coupling element is a carabiner or a shackle.

In a preferred embodiment, at least the first connecting section and the second connecting section and, if present, the first coupling section of the flexible stop means are arranged in the interior of the housing, the interior being in turn delimited at least in sections by inner walls of the housing components.
In a less preferred embodiment, at least the first connecting section and the second connecting section and, if present, the first coupling section of the flexible stop means are arranged outside the housing.

The first connection region is preferably formed by an at least first housing wall section of the first housing component. This first housing wall section is preferably encompassed by a housing wall aligned parallel to the vertical axis (for example a housing jacket with a hollow cylindrical shape of the first housing component) or a cover plate of the first housing component oriented normal to the vertical axis.
The second connection region is preferably formed by a second housing wall section of the second housing component. This second housing wall section is preferably encompassed by a housing wall aligned parallel to the vertical axis (for example a housing jacket with a hollow cylindrical shape of the second housing component).

In particular, the second housing component comprises at least one housing wall aligned parallel to the vertical axis. In the case of the hollow cylindrical shape of the second housing component, this can be provided by a housing jacket which has an outer jacket surface which is concentric with the vertical axis and an inner jacket surface which delimits sections of the interior of the housing. In the case of a hollow cuboid shape of the second housing component, the housing wall can be provided by each side wall of the hollow cuboid, which is correspondingly aligned parallel to the vertical axis.
In this case, the fastening area of the second housing component is preferably provided by a base plate which rests on a support surface of the foundation and is connected to the at least one housing wall.
This. The base plate can be closed, have openings for attachment to the foundation, for power supply or for wired communication, or can be designed as an inner and / or outer collar.
In this case, the predetermined breaking area of the second housing component is preferably provided by a first housing wall section of the at least one housing wall, which is spaced parallel to the vertical axis by at least the thickness of the base plate in the connection region thereof to the at least one housing wall from the support surface of the foundation.
Preferably, the second connection area of the second housing component is provided by a second housing wall section of the at least one housing wall, which connects to the first housing wall section in the direction facing away from the foundation parallel to the vertical axis. In addition, this second housing wall section can have the second connection point or means for fastening the second connection point.

The second housing component preferably corresponds to said lower housing component. This design enables the flexible lifting means to be used in a particularly efficient and cost-effective manner.

The second housing component is less preferably not the lower housing component. To achieve an effect according to the invention, which includes the lower housing component, it is necessary in this case that the lower housing component is connected to the second housing component via a further flexible attachment means. The above statements regarding the formation of a second housing component, which is fastened directly to a foundation of the traffic monitoring arrangement, can in this case be transferred to the lower housing component.

The first housing component is preferably the uppermost of all housing components of the housing which is arranged the most distant from the foundation. This design enables the flexible lifting means to be used in a particularly efficient and cost-effective manner.
Less preferably, the first housing component is not the uppermost of all housing components of the housing which is arranged the most distant from the foundation. In order to achieve an effect according to the invention, which includes the lower housing component, it is necessary in this case to connect the uppermost housing component as a third housing component to the first housing component via a further flexible stop means.
Thus, the traffic monitoring arrangement according to the invention can be characterized in that its housing has a third housing component which is arranged on a side of the first housing component which faces away from the second housing component, and in that it has a plurality of flexible lifting means, of which a first flexible lifting means is said flexible lifting means , by means of which the first housing component and the second housing component are connected to one another, and a second flexible stop means is a further flexible stop means by which the first housing component and the third housing component are connected to one another.

In particular, this vertical axis opens into a foundation area of the traffic monitoring arrangement, for example a foundation of the traffic monitoring arrangement or a foundation component of the housing.

However, the second housing component is particularly preferably the lower housing component and the first housing component is that of all of the housing components of the housing which is arranged the most distant from the foundation. This design ensures a particularly efficient and cost-effective use of only a single flexible sling.

FIRST EMBODIMENT

Fig. 1 shows the schematic cross-sectional view along the vertical axis 27 of the housing 20 of a traffic monitoring arrangement 10 according to the invention according to a first exemplary embodiment, the cross-sectional plane being perpendicular to the detection direction of the traffic monitoring devices 11, 12 and 13, which is illustrated by the detection direction symbol 19, which is directed out of the display plane Symbolizes the direction of detection. The direction of detection is ideally oriented anti-parallel to the direction of traffic. However, since the invention is a traffic monitoring arrangement 10 designed for foundation in the roadside ground, the detection direction typically deviates by 10 ° to 45 ° from the opposite direction of traffic. The housing 20 is fastened to a foundation 30, which is founded in the roadside floor, and has five housing components 21, 22, 23, 24 and 25 arranged one above the other along the vertical axis 27. The vertical axis 27 is oriented perpendicular to the upper side 35 of the foundation 30 facing the housing 20. This foundation top 35 provides a support surface 35 for the housing 20.

A housing component referred to as the first housing component 21 also counts as the uppermost housing component in the sense that the first housing component 21 is that of all housing components 21, 22, 23, 24 and 25 which is arranged furthest away from the foundation 30 along the vertical axis 27 .
A housing component referred to as the second housing component 22 also counts as the bottom housing component in the sense that the second housing component 22 is that of all housing components 21, 22, 23, 24 and 25 which is arranged along the vertical axis 27 closest to the foundation 30.

The housing components 21, 22, 23, 24 and 25 are designed in the form of circular hollow cylinders, the lateral surfaces of which provide sections of the interior of the housing 20. They each have on their undersides facing the foundation 30 and on their tops facing away from the foundation an inward collar, oriented at right angles to the wall, the respective outside of which has a flange surface for the non-positive connection between two immediately adjacent housing components, which is brought about by bolts 28a and nuts 28b 21 and 23, 23 and 24, 24 and 25 and 25 and 22. Exceptions form on the one hand the top of the upper (first) housing component 21, which is designed as a closed cover plate, and on the other hand, the (underside) collar of the underside of the lower (second) housing component 22, the outside of which serves as a support surface for resting on the support surface 35 of the Foundations 30 serves. The second housing component 22 is fastened directly to the foundation 30 by means of a fastening plate 31 and fastening screws 32 which penetrate the fastening plate 31 and engage the foundation 30 in a non-positive manner by the fastening plate 31 in its edge region on the inside of the underside collar of the second housing component 22 rests.

The foundation 30 consists predominantly of concrete and can have a stainless steel insert (not shown), which provides a particularly flat contact surface 35 and internal thread for the reliable engagement of the fastening screws 32. Furthermore, the foundation 30 can have at least one channel (also not shown) with an inlet opening facing the housing 20 and an outlet opening facing away from the housing 20, via which power supply and / or signal lines (also not shown) are led into the housing 20, preferably via an opening in the mounting plate 31, which is also not shown.

A traffic monitoring device 11, 12 and 13 is arranged in each of the intermediate housing components 23, 24 and 25 arranged between the first housing component 21 and the second housing component 22: In the second uppermost housing component 23 there is a vehicle contour detection device 11 (for example a LIDAR, a RADAR, a time Of-flight camera or a stereo camera) in the interior of the housing component 23 (for example on the inside of the wall of the housing component 23); In the third uppermost housing component 24, an image recording device 12 (for example a traffic surveillance camera) is fastened in the interior of the housing component 24 (for example on the inside of the wall of the housing component 24); In the second lowest housing component 25 is a vehicle-to-infrastructure communication device 13 (for example a DSRC device, DSRC = dedicated short-range communication) for radio-assisted interrogation of data of a passing vehicle in the interior of the housing component 25 (for example on the inside of the wall of the Housing component 25) attached.

The housing component walls can be designed in sections as a door, flap or loading front of a pull-out, the traffic monitoring devices 11, 12 and 13 each being fastened to the corresponding door, flap or pull-out, so that when a housing component is opened via the door, flap or loading front there is good accessibility to the respective traffic monitoring device.

In this perspective view, not shown, the intermediate housing components 23, 24 and 25 have openings which allow the detection of, in particular, optical and / or electromagnetic signals of the vehicle Permit traffic monitoring devices 11, 12 and 13 and for example in Fig. 2 under reference numerals 23a and 24a and in Fig. 2 ' are shown under reference number 25a. These housing openings can by material permeable to the optical and / or electromagnetic signals, for. B. window glass, be closed to protect the interior of the housing 20 - and thus also the traffic monitoring devices 11, 12, and 13 - from the weather.

In the interior of the lower, second housing component 22, a data processing device 15 is fastened, which is designed to take measured values from the traffic monitoring device 11, 12 and / or 13 - for example a vehicle contour of a passing vehicle detected by the vehicle contour detection device 11, an image recording of the passing vehicle detected by the image recording device 12 Vehicle and / or a data record acquired by the DSRC device, which represents a vehicle state of the passing vehicle - to be received, processed and outputted the result of the processing, preferably via a WLAN or mobile radio communication device (not shown) included in the traffic monitoring arrangement to a traffic monitoring vehicle and / or a traffic monitoring center.

The housing 20 comprises a cordage formed as a braided line 40 as a flexible attachment means according to the invention, which is arranged entirely in the interior of the housing. The braided line 40 has a 32-fold braided sheath with fibers made of Vectran ® and a 12-fold braided core of fibers made of Dyneema ® and has one. Diameter of 12mm. It has a first connecting section 41 with a thimble spliced into a rope eye, which is arranged in the first, upper housing component 21. It also has a second connecting section 42 with a thimble spliced into a rope eye, which is arranged in the lower, second housing component 21.
Finally, the braided line 40 has a first coupling section 45, via which the first connecting section 41 is coupled to the second connecting section 42 and which extends over the third housing component 23, the fourth housing component 24 and the fifth housing component 25, wherein it extends through guide elements 47 in the Housing guided accordingly, takes different alignments. In particular, this means that a section of the first coupling section 45, which is arranged in one of the intermediate housing components 23, 24 and 25, has an alignment in the direction parallel to the vertical axis 27, which does not match a section of the first coupling section 45 in other intermediate housing components 24 , 25 or 23 overlaps. In short: a first section of the first coupling section 45 is not in alignment with a second section of the first coupling section if the first and the second section are arranged in different intermediate housing components 23, 24 and 25.

The first connection section 41 is fastened to a first connection area 211 of the first housing component 21 by means of a first connection means designed as a carabiner 61 via a first connection point designed as an eyebolt 51, the first connection area 211 being provided by the cover plate of the first housing component 21.
A shackle can also be used instead of the carabiner 61.
The second connecting section 42 is by means of a second connecting means designed as a further flexible stop means 62 (a braided line of the same type as the flexible line according to the invention used here Attachment means) via two connection points designed as cover plates 52 (also called eye plates, eyelet plates or mast plates) with a second connection area 221 of the second housing component 22.
The further flexible stop means 62 not only provides the connection function but also the function of a tensile force limiter 49 by deflecting tensile forces acting on the braided line 40 from the vertical axis direction in the direction of the vertical axis 27 and thus causing a tension-dependent compliance in the direction of the vertical axis 27.
The second connection region 221 is provided by a jacket region of the wall of the second housing component 22 which is concentric with respect to the vertical axis 27 and which is spaced apart in the direction of the vertical axis by an attachment region 223 of the second housing component 22 and a predetermined breaking region 222 of the predetermined region arranged between the fastening region 223 and the second connection region 221 second housing component is arranged. The fastening area 223 of the second housing component 22 is at least provided by the lower collar and the lower casing area which is concentric with respect to the vertical axis 27 and which adjoins the lower collar and does not exceed the thickness of the fastening plate 31 in the direction of the vertical axis.
The predetermined breaking area 222 of the second housing component closes the fastening region 223 in the direction of the vertical axis facing away from the foundation 30 and is provided by the jacket region of the housing component 22 which is concentric with respect to the vertical axis 27 and is located between the fastening region 223 and the second connecting region 221.
In the event of a vehicle impacting the housing 20 in an impact region above the fastening region 223, a compressive force is exerted on the housing 20 essentially perpendicular to the vertical axis 27. The housing 20 cannot yield to this pressure force, at least in the fastening region 223. A shear stress is therefore formed between the impact region and the fastening region 223, which is greatest in the vicinity of the fastening region 223, which is relatively small in relation to the impact region and in which a resistance force opposing the compressive force builds up. Therefore, in the predetermined breaking area 222 localized according to the invention, a main area 20 'of the housing 20 is most likely to be sheared off from the fastening area 223 of the housing 20 which consequently remains on the foundation. Since the braided line, which holds the housing components 21, 22, 23, 24, 25 is to be secured, is fastened in a second connection area 221, which is encompassed by the main area 20 'which is subject to possible shearing, the cohesion of the sheared housing components 21, 23, 24, 25 and partly 22 also remains secured in the event of actual shearing .

In order to secure the data processing device 15, which is located at the level of the predetermined breaking area 222 in the vertical axis direction, against release from the sheared-off bond of the main area 20 ', the data processing device 15 is also connected to a housing component area of the main area via a flexible attachment means. In this case, the data processing device 15 is latched into the further flexible attachment means 62 by means of a karabiner.

In the Figures 2 , 3rd , 4th , 5 and 6 , which form representations to explain the following exemplary embodiments, no traffic monitoring devices 11, 12, 13 and data processing device 15 are shown in order to improve the clarity and to concentrate the content shown on the feature that disputes the characterizing part of the invention.

SECOND EMBODIMENT

The second exemplary embodiment of a traffic monitoring arrangement 10 according to the invention is shown in FIG Fig. 2 is shown in a schematic cross-sectional view along the vertical axis 27 of the housing 20, the cross-sectional plane lying in the plane of the detection direction of the traffic monitoring devices, which is illustrated by the detection direction symbol 19, which symbolizes a detection direction lying in the representation plane.

The second exemplary embodiment differs from the first exemplary embodiment essentially in three features: a) the provision of an intermediate piece 29 serving as a predetermined breaking point, b) the arrangement of the first coupling section 45 in the housing 20 and c) the design of the tensile force limiter 49.

Thus, the traffic monitoring arrangement 10 of this second exemplary embodiment provides an intermediate piece 29, which at the same time forms the bottom housing component (that which is arranged closest to the foundation 30 of all housing components on the vertical axis 27) and serves as a predetermined breaking point according to the invention. The lower, second housing component 22, as the second lowest housing component, which according to the invention provides the second connection region 221, is indirectly attached to the foundation 30 via this intermediate piece 29.
The underside of the intermediate piece 29 facing the foundation 30 is provided by a base plate 33 of the intermediate piece 29, which forms a fastening area 293 of the intermediate piece 29 and whose inner side facing away from the foundation 30 has a concentric to the vertical axis 29 that immediately adjoins the inner surface of the jacket area of the intermediate piece 29 Has groove 34. In the event of an impact, the shear stresses accumulate on the inner edge of the groove 34 facing the jacket area, so that the partial area of the jacket area of the intermediate piece 29, which directly adjoins the groove 34, can be regarded as the predetermined breaking area 292 of the intermediate piece 29, which there is the predetermined breaking point the traffic monitoring arrangement 10.
Because in the second housing component 22 there is both the second connection section 42 of the braided line 40 and the connection point 52 designed as a tensile force limiter 49, which is attached to the second housing component 22 by means of bolt screws 28a and nuts 28b - more precisely: on its underside collar, which forms the second connection region 221 provides - is attached.
An alternative description of these relationships can be found in the Fig. 2 ' pursue a cutaway representation of the Fig. 2 of the traffic monitoring arrangement 10, which is limited to the lower housing component and the components of the foundation 30 and the second lowest housing component connected directly to it: namely, the connection point 52 is fastened not only to the second lowest but also to the lowest housing component via the bolt screws 28a and nuts 28b , which is therefore contrary to the previous description Fig. 2 according to Fig. 2 ' can also be understood as a second housing component 22, to which in the side facing away from the foundation 30 according Fig. 2 ' the third intermediate housing component 25 is connected, which in Fig. 2 was the second housing component 22. Accordingly, according to Fig. 2 ' the second connection region 221 through the top-side collar of the second housing component 22, the fastening region 223 through the underside bottom plate 33 of the second housing component 22 and the predetermined breaking region 222 through the jacket region of the second housing part 22, which in the direction of the vertical axis between the fastening region 223 and the second connection region 221 is arranged.

The arrangement of the first coupling section 45 in the housing 20 is clearly shown in FIG Fig. 2 in that it takes place essentially along a straight connecting line between the first connecting section 41 and the second connecting section 42, which is parallel to the vertical axis 27. In each case a first section of the first coupling section 45 is arranged in the alignment of a second section of the first coupling section 45 parallel to the vertical axis 27, the first section and the second section being arranged in different intermediate housing components 23 and 24.

The second connection point 52, which acts as a tensile force limiter 49, is shown in FIG Fig. 2a shown separately in an oblique view. It consists of two plate sections 55 and 57 adjoining one another at right angles and was produced by bending a single, flat plate made of stainless steel with a thickness of 4 mm. A first plate section 55 serves as a connection section 55 for fastening the second connection point 52 to the second connection area 221 and, for this purpose, has four through connection openings 56 which serve to receive the shaft of the stud bolts 28a. A second plate section 57 in the form of a tab serves as a stop section 57 for fastening the second connecting section 42 by means of a karabiner 62 ( Fig. 2 and Fig. 2 ' ) and assigns a. Stop opening 58, which is provided for mutual engagement with the carabiner 62.
The first plate section 55 also has two tear seam structures 59 which were introduced into the plate by etching or laser cutting and delimit a plate region of the first plate section 55 which opens into the second plate section 57. These tear seam structures 59 are torn when a tensile force acting on the stop section 57 in the direction of the vertical axis 27 exceeds a limit tensile force. In this case, the tearing is preceded by a deflection of the second plate section 57 relative to the first plate section 55, at least partially parallel to the vertical axis 27. Another such deflection occurs with the tearing and after the tearing, the connection established via the flexible stop means 40 between the first connection area 221 and the second connection area 222 being retained by the yielding of the second connection point 52 which limits the tension.

In the case of this exemplary embodiment, the connection point 52 is arranged between the screw heads of the screws 28a and the underside collar of the second lowermost housing component, with the fact that the screws 28a and nuts 28b at the same time connecting means for connecting the second lowest housing component to the lowermost housing component and fastening means for fastening of the connection point 52 on the underside collar of the second lowest housing component, as described, the ambivalent understanding is permissible that the second housing component 22 is both the second lowest housing component ( Fig. 2 ) as well as the lowest housing component ( Fig. 2 ' ) can be provided.
The same applies to the case of an - not shown - alternative arrangement of the connection point 52 between the nuts 28b and the top-side collar of the bottom housing component: analogously to the case described above, in this case it applies that the screws 28a and nuts 28b simultaneously connect the means for connecting the are the second lowest housing component with the lowest housing component and fastening means for fastening the connection point 52 to the top-side collar of the lowermost housing component. In this case, too, the same ambivalent understanding as in the previously described case is permissible, that both the second lowest and the lowest housing component can correspond to the second housing component according to the invention.

THIRD EMBODIMENT

The third exemplary embodiment of a traffic monitoring arrangement 10 according to the invention is shown in FIG Fig. 3 is shown in a schematic cross-sectional view along the vertical axis 27 of the housing 20, the cross-sectional plane lying in the plane of the detection direction of the traffic monitoring devices, which is illustrated by the detection direction symbol 19, which symbolizes a detection direction lying in the representation plane.

The third exemplary embodiment differs from the first exemplary embodiment essentially by three features: a) the design of second housing component 22, b) the arrangement of first coupling section 45 in housing 20 and c) the design of tensile force limiter 49.

In contrast to the first exemplary embodiment, the second housing component 22 has, on its underside facing the foundation 30, a base plate 33 which rests on the foundation 30 and has a plurality of continuous fastening openings through which the shafts of the screws 32 for fastening the housing 20 to the foundation 30 are guided become. The jacket region of the housing component 22 which is concentric to the vertical axis 27 and which is limited to the thickness of the base plate in the direction of the vertical axis forms the fastening region 223 of the housing component 22. The second connecting region 221 is provided by that jacket region of the housing component 22, in the fastening means 521 (in this case a screw) for fastening the second connection point 52 (in this case a fastening angle 52 with a stop opening for the engagement of a karabiner 62, which in turn is latched into the thimble of the eye 42 as the second connecting section of the braided line 40) engages, and which is spaced from the fastening region 223 in the direction of the vertical axis 27 by a casing region surrounding the housing component 22, which is designed as a predetermined breaking region 222.
This predetermined breaking area 222 has a second housing component material that is more brittle than a first housing component material in areas of the second housing component 22 outside of the predetermined breaking region 222. For example, the second housing component material has a more fine-grained structure than the first housing component material, which, for example, in the first housing component material due to thermal and / or mechanical treatment was generated in the predetermined breaking area 222. On the other hand, the second housing component material can also differ chemically from the first housing component material, which is produced by the action of an embrittlement agent, e.g. B. of hydrogen on electrolytic copper Cu-ETP or martensitic steel, was generated on the first housing component material in the predetermined breaking area 222. Finally, the housing component 22 can also be in three parts, the predetermined breaking area 222 also as a predetermined breaking ring separate from a lower housing component section, which comprises the fastening region 223 including the base plate 33, and the upper housing component section, which comprises the second connecting region 221, and that of a second housing component material be made, which is completely different from the first housing component material of the lower and the upper housing component section. In the course of production, the predetermined breaking ring may have been joined between the lower and the upper housing component section, for example by means of soldering.

The arrangement of the first coupling section 45 in the housing 20 is clearly shown in FIG Fig. 3 in that it takes place essentially along a straight connecting line between the first connecting section 41 and the second connecting section 42, which is parallel to the vertical axis 27. In each case, a first section of the first coupling section 45 is arranged in the alignment of a second section of the first coupling section 45 parallel to the vertical axis 27, the first section and the second section being in different intermediate housing components 23 and 24, 23 and 25 and / or 24 and 25 are arranged.

In this third exemplary embodiment, a belt energy absorber 49 serves as a traction force limiter and is arranged as part of the flexible stop means between the first coupling section 45 and the second connecting section 42, which are linked to one another via the belt energy absorber 49. This arrangement alternatively allows the view that the band energy absorber 49 is either part of the first coupling section 45 or part of the second connecting section 42.

The fourth exemplary embodiment of a traffic monitoring arrangement 10 according to the invention is shown in FIG Fig. 4 is shown in a schematic cross-sectional view along the vertical axis 27 of the housing 20, the cross-sectional plane being perpendicular to the detection direction of the traffic monitoring devices (not shown), which is illustrated by the detection direction symbol 19, which symbolizes a detection direction directed out of the display plane.

The fourth exemplary embodiment differs from the first exemplary embodiment essentially by three features: a) the formation of second housing component 22, b) the formation and arrangement of the braided line 40 in the housing 20 and c) the lack of a tensile force limiter 49.

First, the design of the second housing component 22 is the same as that of the third exemplary embodiment, with the difference that the predetermined breaking area 222 is not provided by a material structure or material that differs from the rest of the housing component 22, but rather by a material deficit in the casing of the housing component 22, which is caused by an in the inner wall groove created in the jacket.

The formation and arrangement of the braided line 40 in the housing 20 is such that the braided line 40 makes the connection between the first, uppermost housing component 21 and the second lowermost housing component 22 several times - in this case, for example, twice, a three or fourfold connection also being possible ) provides. Specifically, the first connecting section 41 is a first end section of the braided line 40, which is fastened via a carabiner 61 to an eyebolt 51 which is screwed into the cover plate of the first housing component 21. A third connecting section 43 of the braided line 40 is provided by a second end section of the braided line 40 and is fastened via a carabiner 63 to an eyebolt 53, which is also screwed into the cover plate of the first housing component 21. The second connecting section 42 of the braided line 40 is provided by a central section of the braided line, which is fastened to the second connecting region 221 of the second housing component 22, which is through the wall region 221 of the second connecting part 221, which are provided by two cover plates 52 Jacket of the housing component 22 is provided, which is spaced along the vertical axis 27 from the fastening area 223 by the predetermined breaking area 222.
The first coupling section 45 of the braided line 40, which connects the first connecting section 41 to the second connecting section 42, is arranged in the intermediate housing components 23, 24 and 25.
A second coupling section 46 of the braided line 40, which connects the third connecting section 43 to the second connecting section 42, is likewise arranged in the intermediate housing components 23, 24 and 25. As a result, the course of the braided line 40 in the housing 20 takes the form of a letter U which is upright with respect to a direction pointing away from the foundation along the vertical axis.
As a result of this multiple linking of first housing component 21 and second housing component 22, the tensile forces acting on braided line 40 in the event of breakage can be distributed over two parallel first and second coupling sections 45 and 46 of the braided line, so that a tensile force limiter can be dispensed with.

FIFTH EMBODIMENT

The fifth exemplary embodiment of a traffic monitoring arrangement 10 according to the invention is shown in FIG Fig. 5 is shown in a schematic cross-sectional view along the vertical axis 27 of the housing 20, the cross-sectional plane being perpendicular to the detection direction of the traffic monitoring devices (not shown), which is illustrated by the detection direction symbol 19, which symbolizes a detection direction directed out of the display plane.

The fifth exemplary embodiment differs from the fourth exemplary embodiment essentially by three features: a) the arrangement and configuration of second housing component 22, b) the configuration and arrangement of braided line 40 in housing 20 and c) the formation of a predetermined breaking area 292 in intermediate piece 29.

In the case of this fifth exemplary embodiment, the second housing component 22 is not the lowest housing component, but the second lowest housing component of the housing 20, which is fastened to the foundation 30 by means of an intermediate piece 29, which is also a housing component of the housing 20. The intermediate piece 29 itself has a base plate 31 facing away from the second housing component 22 and facing the foundation 30, with openings through which the shafts of fastening screws 32 are guided for engagement in the foundation 30.
The intermediate piece 29 is the predetermined breaking point according to the invention of this fifth exemplary embodiment of the traffic monitoring arrangement 10 according to the invention.

Compared to the fourth exemplary embodiment, the arrangement of the braided line 40 is reversed, specifically in that it has the shape of a letter U, ie the shape of a ∩, which is mirrored perpendicular to the vertical axis with respect to a direction pointing away from the foundation along the vertical axis.
Specifically, the first connecting section 41 is provided by a central section of the braided line 40. This middle section is connected to the first housing component 21 by means of two snap-in carabiners 61 by means of two cover plates 51 serving as the first connection points, which are fastened on opposite sides of the cover plate of the first housing component 21 with respect to an imaginary plane that includes the vertical axis 27 perpendicular to the plane of representation attached.

The second connecting section 42 is provided by a first end section of the braided line 40, which is fastened to the housing wall of the second housing component 22 by means of a karabiner 62 via a second connection point 52, which comprises a fastening angle with a stop opening for the latching of the karabiner 62.
A third connecting section 43 is provided by a second end section of the braided line 40, which is fastened to the housing wall of the second housing component 22 by means of a karabiner 63 via a third connecting point 53, which comprises a fastening angle with a stop opening for the latching of the karabiner 63.
The first coupling section 45 of the braided line 40, which connects the first connecting section 41 to the second connecting section 42, is arranged in the intermediate housing components 23, 24 and 25.
A second coupling section 46 of the braided line 40, which connects the third connecting section 43 to the second connecting section 42, is likewise arranged in the intermediate housing components 23, 24 and 25.

The intermediate piece 29 in turn has a fastening area 293, which is limited in its extension parallel to the vertical axis 27 to the thickness of the base plate 33 of the intermediate piece 29. The intermediate piece likewise has a predetermined breaking area 292, on which the shear stresses concentrate in the event of an impact in such a way that shearing occurs in the predetermined breaking area 292. Unlike the exemplary embodiments two, three and four, this predetermined breaking area is neither structurally nor materially defined by the other wall areas of the jacket in the sense of an intentionally introduced weakening. Similar to the first exemplary embodiment, it is defined in that it connects directly to the defined fastening region 293 in the direction away from the foundation parallel to the vertical axis.
An embodiment of the fastening area and the predetermined breaking area of the lowermost housing component in the first embodiment, which is analogous to the intermediate piece 29 of this embodiment, is also possible there.

Both the fourth and the fifth exemplary embodiment can be modified such that two I-shaped braided lines are used instead of a single U-shaped braided line 40. The Figures 4 and 5 would have to be changed in such a way that instead of said middle sections (in the fourth exemplary embodiment the second connecting section 42, in the fifth exemplary embodiment the first connecting section 41) there would be end sections of different braided lines according to the pattern of the end sections already described, which would be at the corresponding connecting points on the second housing component 22 (fourth embodiment) or on the first housing component 21 (fifth embodiment).

SIXTH EMBODIMENT

The sixth exemplary embodiment of a traffic monitoring arrangement 10 according to the invention is shown in FIG Fig. 6 Shown in a schematic external view of the housing 20, the display plane being perpendicular to the detection direction of the traffic monitoring devices (not shown), which is illustrated by the detection direction symbol 19, which symbolizes a detection direction directed out of the display plane.

The sixth exemplary embodiment essentially differs from the fifth exemplary embodiment essentially by three features: a) the flexible stop means 40 is not in the housing 20 but outside the

Housing is arranged on the housing, b) the bottom plate of the bottom, second housing component 22 is designed as an outer collar and c) the flexible lifting means itself.

In particular, instead of the textile rope of the previous exemplary embodiment, a chain 40 with links made of stainless steel is used, which is stiffened by a curtain material cladding.
Sections 41, 42, 43, 45 and 46 of the chain and their arrangement with regard to fastening to the first housing component 21 and second housing component 22 correspond to that of the fifth exemplary embodiment, with the difference that the arrangement and the fastening are not in the housing 20 but outside the housing Housing 20 takes place.

To attach the chain to the housing 20, connecting points 51, 52 and 53 are provided, which are U-shaped and each have an opening at their base, which is oriented away from the housing wall with respect to the end faces of the legs, for receiving a shaft of a screw 51a in each case , 52a and 53a, which are guided through a chain link arranged between the legs of the respective connection points and engage in an internal thread of the respective housing component wall of the relevant housing component 21 or 22.
Further connection points of the same type, not designated, are used for section-by-section attachment of the chain 40 to the intermediate housing components 23, 24 and 25.

The bottom plate 33 of the bottom housing component, which is designed as an outwardly oriented collar and which at the same time provides the fastening region 223 according to the invention, is used to fasten the lowermost housing component 22 to the foundation 30. The predetermined breaking area 222 of the housing component 22 adjoins the outer collar 33 in the direction facing away from the foundation 30 on the inner edge of the housing wall parallel to the vertical axis 27.

All of the exemplary embodiments can be modified in such a way that the braided line / chain 40 is broken down into a plurality of parts along its longitudinal axis, which in turn have connecting sections at the end sections for fastening to the intermediate housing component (s) 23, 24 and / or 25, in / on which the respective connecting section of the braided line / chain 40 is arranged. This separation changes the property of an originally intermediate housing component 23, 24 and / or 25 in such a way that it acts as one of several first housing components and / or one of several second housing components in the sense of the invention. Such a piece-wise, multiple serial application of the principle according to the invention over several pairs of indirectly or directly adjacent housing components can be indicated if a single, longer, flexible lifting means 40 cannot or should not be laid in its entirety on / through the housing, for example due to a lack of space in the Housing or cost savings on the housing.

While in the exemplary embodiments always on a foundation 30 as the foundation component of the
Traffic monitoring device was referred to, the foundation 30 can be replaced by a foundation member of the housing 20 in each embodiment. Such a foundation component can also be a housing component of the housing 20 which, together with the other housing components 21, 22, 23, 24 and optionally 25, encloses a common interior of the housing 20.
