[2] Company brochure "Products Guide 17.2" from the company Pilomat S.r.l.,

distributed among others via the Internet and downloaded on

July 20, 2017.

With such Fahrperrabsperrvorrichtungen areas that are to be protected, at least temporarily safe from being driven by foreign vehicles, be shut off. Such blocking elements are, for example, at the entrance of pedestrian areas, in front of public buildings or

Government buildings, used to secure events or the like.

In the simplest version fixed bollards are provided. Retractable bollards may also be provided to allow for temporary entry or for authorized vehicles. These are, for example, moved electro-hydraulically or electromechanically and are controlled by a controller that can be provided in a central or decentralized on-site. Instead of Bollards can also use other blocking elements, such as City Gates, or

Roadblocker be used. Under Roadblocker, e.g. hochfahrbare ramps referred to, for example, to secure highly sensitive

Security areas against terrorist attacks or other attacks can be used with heavy vehicles.

Such blocking elements have proven themselves.

The object of the invention is to provide a Fahrwegabsperrvorrichtung to be used at least one such blockade element, which is improved in terms of their longer safe operation with simplified handling.

To solve this problem, the Fahrwegabsperrvorrichtung is proposed according to claim 1.

It is preferred that the condition monitoring means is adapted to issue a warning when a predetermined threshold for a number of impacts and / or a predetermined threshold for a strength of a

Stoßes is exceeded.

It is preferred that the blockage element between a passage passage allowing passage and a passage blocking

Locking position is movable.

It is preferable that the blockage member is selected from a group comprising a bollard, a retractable bollard, a hydraulically or electro-hydraulically movable bollard, an electromechanically movable bollard, a barrier, and a roadblocker.

It is preferred that the shock sensor comprise one or more sensing elements selected from a group comprising a position sensing element, an accelerometer, a piezoelectric element, a pressure sensing element, a vibration sensing element and a position and / or vibration sensor for sensing a Has situation and / or a vibration of the blocking element.

It is preferred that a recording device is provided for recording data detected by the shock sensor via impacts applied to the blocking element.

It is preferable that a maintenance interval display is connected to the shock sensor to allow a time until the next maintenance of the

Fahrwegabsperrvorrichtung in response to an output of the shock sensor to determine.

According to a further aspect, the invention provides a road-barrier system comprising one or more infrastructure cut-off devices according to one of the above-described embodiments and a central service unit, at which a state dependent on outputs of the shock sensor at least one Blockadeelements of or the Fahrwegabsperrvorrichtung (s) can be displayed or recorded.

According to a further aspect, the invention provides a method for operating a drive shut-off device, which comprises a blocking element for blocking a

Track has, comprising:

Detecting shocks against the blockage element and

Specification of repair or maintenance times or repair or

Maintenance intervals for repair or maintenance of the blockade element in

Dependence on the number and / or strength of the detected shocks.

Preferably, the method relates to the operation of a road closure device according to one of the embodiments described above.

Advantageous embodiments of the invention relate to the idea of a position and / or vibration sensor in e.g. retractable hydraulic or

Install electromechanical bollards or other access systems such as roadblocks or barriers, etc. With this sensor can be detected whether the bollard was hit or how heavy a shock was. Preferably, such a detection is recorded via a service module and a

Message to a corresponding server for forwarding to a

Service Center issued. This way, messages can be read remotely. In particular, maintenance intervals can be adapted to a load of blocking elements. Also, a message may be issued that a blockage element requires repair or replacement.

The detection of shocks or bumps are particularly advantageous in bollards or other blockage elements of the type in question here, since these are permanently approached in practice by vehicles and such an event can be detected in a very short time by a message of the device status to each connected service center can. In this way, it can be ensured that even a blockade element which is weakened, for example, by a violent shock or by repeated starting, does not become an uncertainty factor, but can be repaired or replaced in good time.

As a result, the security provided by the Fahrwegabsperrvorrichtung is increased overall. Furthermore, the monitoring of the same is more comfortable, and it can avoid unnecessary maintenance and control trips.

The respective Fahrwegabsperrvorrichtung 12 has at least one

Blockade element 14 for blocking a route 16 for two-lane

Vehicles on.

As blocking elements 14, all blocking elements can be used, as can be seen from the aforementioned references [1] and / or [2]. Reference is made to the above references [1] and [2] for more details on the construction of such blocking elements 14.

Accordingly, the blocking element 14 may be a bollard 18, in particular a fixed bollard 18a or a retractable bollard 18b. As another example of a blocking element 14, a road blocker 20 with a ramp which can be raised is shown in FIG.

The embodiments of FIGS. 2 to 4 show further embodiments of the bollard 18. In Fig. 5 is shown as a further embodiment of the blockade element 14 a lowerable chain 22 with the corresponding side columns 24 (only one shown). In Fig. 7 is shown as a further example of the blocking element 14, a Absperrbalken 26 which is movable in solid side columns 24 upwards in a blocking position 36 and down in a drive-through position 38. In another embodiment, not shown, that is

Blockade element formed as a barrier.

Accordingly, fixed blockage elements 14 may be provided, or it may be provided that the blocking element 14 is movable between a drive-through position 38 permitting a passage and a blocking position blocking a passageway 36.

For the movement of the blocking element 14, different drives 28 may be provided, which may be designed, for example, as hydraulic drives or electromechanical drives. The infrastructure shut-off system 10 has a central service unit 30, via which the state of the individual blocking elements 14 can be monitored.

In the example of FIG. 1, the service unit 30 is shown in a building 31. Further communication links 32 between the service unit 30 and the Fahrwegabsperrvorrichtungen 12 and the blocking elements 14th

indicated. These communication links 32 may be wired or wireless, e.g. by radio, be trained. In particular, a

Communication connection 32 via a network, for example via encrypted communication via the Internet or via an intranet

provided.

The infrastructure shut-off device 12 has a state monitoring device 34 for detecting a state of the blocking element 14. For example, the condition monitoring device 34 can detect and / or monitor the respective position of the blocking element 14 when the blocking elements 14 are movable between the blocking position 36 and the transit position 38.

Furthermore, the condition monitoring device 34 has at least one

Shock sensor 40 on the respective blockade element 14.

The shock sensor 40 can be designed quite differently.

For example, the shock sensor 40 is formed as a position and vibration sensor 42, as indicated in Fig. 1.

In the embodiment illustrated in FIG. 2, piezoelements 44 are provided

provided, which detect a pressure on an outer wall of the blocking element 14.

In the embodiment in Fig. 3, the shock sensor 40 a

Accelerometer 46 for measuring accelerations. In the exemplary embodiment illustrated in FIG. 4, the shock sensor 40 has a vibration measuring element 48 with a vibration mass whose position and / or movement is detected, for example, capacitively or inductively or optically or via force sensors or the like.

In the embodiment shown in Fig. 5, a force measuring element 50 is provided by means of which a force on a connection between a

Attachment of the blocking element 14 and the blocking region of the blocking element 14 is measured. For example, a tensile force on the chain 22 is measured. Another example of the force sensing element 50 is shown in FIG. 7 where a force is measured between the side pillar 24 and its anchoring 52.

In this way, by the shock sensor 40 shocks against the

Blockade element 14 are detected.

Preferably, the shock sensor 40 is configured to detect an impact force. In particular, a sensor signal dependent on the impact force is output.

As indicated in Fig. 1, the Fahrwegabsperrvorrichtung 12 has a

Control unit 54, may be housed in the electronic elements of the condition monitoring device 34. The control unit 54 may also be designed to control the drive 28. Preferably, the control unit 54 is connected to the service unit 30. It can also be connected to different identification devices not shown for personal or vehicle identification, so that authorized vehicles can be passed. About the service unit 30 and the control unit 54 is a

Remote control of the movable blocking element 14 possible.

Furthermore, a remote monitoring of the state of the blocking element 14 is made possible.

The condition monitor 34 may further include a

Recording device 56 for recording status data of the Blockade element 14 have. In particular, data provided by the shock sensor 40 may be recorded.

For example, the number of impacts detected or the number of impacts may be counted above a certain threshold for impact strength. Furthermore, the total impact energy applied to the blocking element 14 could be recorded cumulatively.

On the basis of these data, in particular the number of impacts, the impact strength and / or the cumulative impact energy, an indicator can be generated, which can be a measure of a pending maintenance or upkeep. For example, the display may generate a bar indicating a measure of the condition between the completely intact or mint condition and a condition requiring replacement or at least repair of the jam member.

This is illustrated in FIG. 6, which illustrates an example of a display on a monitor or other display of the service unit 30. There are states of a first blockade element 14 - shown as "1" - and a second blockade element 14 - shown as "2" - reproduced. With "A" and "B" respectively the blocking position 36 and the passage position 38 can be displayed. Further illustrated is a repair and maintenance interval display 58 in the form of a progress bar or the like indicating a condition between "fully intact" and "replacement or repair necessary". Further, a warning indicator 60 may be provided which indicates the need for immediate repair.

In a non-illustrated embodiment, the blocking element is designed in the form of a barrier with a movable barrier boom, wherein a position sensor and / or acceleration sensor is arranged in or on the barrier boom. A sensor could, for example, sit in the barrier boom and also take over the detection there. In combination with a layer switch that detects when the barrier is in horizontal or other rest position, a horizontal movement is detected during a start-up damage. LIST OF REFERENCE NUMBERS
