Stellplatzsensoren sind in der Regel teuer. Es besteht daher ein Bedarf, diese gegen Diebstahl zu schützen respektive einen Diebstahl zu erschweren.Parking space sensors are usually expensive. There is therefore a need to protect them against theft or to make theft more difficult.

Offenbarung der ErfindungDisclosure of the invention

Die der Erfindung zugrundeliegende Aufgabe ist darin zu sehen, ein Konzept bereitzustellen, welches es effizient ermöglicht, dass ein Diebstahl eines Stellplatzsensors erschwert oder sogar vermieden werden kann respektive effizient detektiert werden kann.The object on which the invention is based is to provide a concept which efficiently enables the theft of a parking space sensor to be difficult or even avoided or to be detected efficiently.

Diese Aufgabe wird mittels des jeweiligen Gegenstands der unabhängigen Ansprüche gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand von jeweils abhängigen Unteransprüchen.This object is achieved by means of the respective subject of the independent claims. Advantageous embodiments of the invention are the subject of dependent subclaims.

Nach einem Aspekt wird eine Sensorvorrichtung zum Überwachen eines Belegungszustands eines Stellplatzes eines Parkplatzes für Kraftfahrzeuge bereitgestellt, umfassend:

  • zumindest einen Stellplatzsensor zum Überwachen eines Belegungszustands eines Stellplatzes eines Parkplatzes,
  • einen ersten elektrischen Energiespeicher für eine elektrische Energieversorgung des zumindest einen Stellplatzsensors,
  • wobei ein erster Stromkreis gebildet ist, in welchem der zumindest eine Stellplatzsensor und der erste elektrische Energiespeicher geschaltet sind,
  • eine Detektionseinrichtung zum Detektieren einer Unterbrechung des ersten Stromkreises,
  • eine in einen zweiten Stromkreis geschaltete Kommunikationsschnittstelle zum Senden eines Signals über ein Kommunikationsnetzwerk bei einer detektierten Unterbrechung des ersten Stromkreises, wobei das Signal die Information umfasst, dass der erste Stromkreis unterbrochen ist,
  • wobei in dem zweiten Stromkreis ein zweiter elektrischer Energiespeicher für eine elektrische Energieversorgung der Kommunikationsschnittstelle geschaltet ist.
According to one aspect, a sensor device for monitoring an occupancy state of a parking space of a parking space for motor vehicles is provided, comprising:
  • at least one parking space sensor for monitoring an occupancy status of a parking space in a parking space,
  • a first electrical energy store for an electrical energy supply of the at least one parking space sensor,
  • wherein a first circuit is formed in which the at least one parking space sensor and the first electrical energy store are connected,
  • a detection device for detecting an interruption in the first circuit,
  • a communication interface connected to a second circuit for transmitting a signal via a communication network in the event of a detected interruption of the first circuit, the signal comprising the information that the first circuit is interrupted,
  • wherein a second electrical energy store for an electrical energy supply of the communication interface is connected in the second circuit.

Gemäß einem weiteren Aspekt wird ein Verfahren zum Überwachen eines Belegungszustands eines Stellplatzes eines Parkplatzes für Kraftfahrzeuge bereitgestellt unter Verwendung der erfindungsgemäßen Sensorvorrichtung, umfassend die folgenden Schritte:

  • Überwachen des Belegungszustands des Stellplatzes mittels des zumindest einen Stellplatzsensors,
  • bei Detektion einer Unterbrechung des ersten Stromkreises mittels der Detektionseinrichtung Senden eines Signals mittels der Kommunikationsschnittstelle über das Kommunikationsnetzwerk, wobei das Signal die Information umfasst, dass der erste Stromkreis unterbrochen ist.
According to a further aspect, a method for monitoring an occupancy state of a parking space of a parking space for motor vehicles is provided using the sensor device according to the invention, comprising the following steps:
  • Monitoring the occupancy status of the parking space by means of the at least one parking space sensor,
  • upon detection of an interruption of the first circuit by means of the detection device, transmission of a signal by means of the communication interface via the communication network, the signal comprising the information that the first circuit is interrupted.

Nach noch einem Aspekt wird ein Parkplatz für Kraftfahrzeuge bereitgestellt, wobei der Parkplatz zumindest einen Stellplatz und zumindest eine dem Stellplatz zugeordnete erfindungsgemäße Sensorvorrichtung umfasst.According to another aspect, a parking space for motor vehicles is provided, the parking space comprising at least one parking space and at least one sensor device according to the invention assigned to the parking space.

Die Erfindung basiert auf der Erkenntnis, dass die obige Aufgabe dadurch gelöst werden kann, dass bei einer Detektion einer Unterbrechung des ersten Stromkreises ein Signal über ein Kommunikationsnetzwerk ausgesendet wird, wobei das Signal die Information umfasst, dass der erste Stromkreis unterbrochen ist. Dadurch kann in vorteilhafter Weise effizient über das Kommunikationsnetzwerk mitgeteilt werden, dass ein unzulässiger Eingriff an der Sensorvorrichtung vorgenommen wurde. Denn ein Unterbrechen des ersten Stromkreises deutet üblicherweise zum Beispiel darauf hin, dass der Stellplatzsensor aus dem ersten Stromkreis entfernt wurde.The invention is based on the finding that the above object can be achieved in that when an interruption in the first circuit is detected, a signal is emitted via a communication network, the signal comprising the information that the first circuit is interrupted. As a result, it can advantageously be efficiently communicated via the communication network that an unauthorized intervention has been carried out on the sensor device. Because an interruption of the first circuit usually indicates, for example, that the parking space sensor has been removed from the first circuit.

Dadurch, dass diese Information über das Kommunikationsnetzwerk versendet wird, kann zum Beispiel ein Betreiber des Parkplatzes effiziente Gegenmaßnahmen ergreifen. Zum Beispiel kann er die Polizei oder ein Sicherheitsunternehmen alarmieren, das sich die Sache vor Ort direkt anschaut. Gegebenenfalls kann dadurch ein Dieb noch rechtzeitig geschnappt werden, was dann letztlich den Diebstahl der Sensorvorrichtung verhindert hätte. Zumindest aber wird ein Diebstahl der Sensorvorrichtung erschwert.By sending this information over the communication network, an operator of the parking lot, for example, can take efficient countermeasures. For example, he can alert the police or a security company that looks directly at the matter on site. If necessary, a thief can still be caught in time, which would then have prevented the theft of the sensor device. At least the theft of the sensor device is made more difficult.

Insbesondere wird der technische Vorteil bewirkt, dass ein Diebstahl respektive ein unerlaubter Eingriff effizient detektiert werden kann.In particular, the technical advantage is brought about that theft or an unauthorized intervention can be detected efficiently.

Es wird also insbesondere der technische Vorteil bewirkt, dass die Information, dass ein unerlaubter Eingriff an der Sensorvorrichtung vorgenommen wurde, auch entfernt von der Sensorvorrichtung zur Verfügung gestellt ist, so dass dann entsprechende Gegenmaßnahmen ergriffen werden können.In particular, the technical advantage is brought about that the information that an unauthorized intervention has been carried out on the sensor device is also made available remotely from the sensor device so that appropriate countermeasures can then be taken.

Das erfindungsgemäße Konzept weist weiterhin den Vorteil auf, dass aufwändige und komplexe und teure Überwachungssysteme, zum Beispiel Videokameras, nicht benötigt werden. Denn so ist die Sensorvorrichtung mit einer eigenen Diebstahlerkennungsvorrichtung, hier die Detektionseinrichtung, ausgestattet, wobei das Detektieren einer Unterbrechung des ersten Stromkreises eine einfache Möglichkeit darstellt, einen unerlaubten Eingriff zu detektieren, verglichen zum Beispiel mit einer Videokamera, deren Videodaten üblicherweise erst aufwändig mittels einer Bildanalyse ausgewertet werden müssen oder durch einen Menschen manuell kontrolliert werden müssen. Ob ein Stromkreis geschlossen oder unterbrochen ist, lässt sich einfach messen und somit feststellen.The concept according to the invention also has the advantage that complex and complex and expensive surveillance systems, for example video cameras, are not required. This is because the sensor device is equipped with its own theft detection device, here the detection device, whereby the detection of an interruption in the first circuit is a simple way of detecting an unauthorized intervention, compared, for example, with a video camera, the video data of which is usually only complicated by means of an image analysis have to be evaluated or manually checked by a human. It is easy to measure and determine whether a circuit is closed or interrupted.

Die Formulierung "zumindest einen Stellplatzsensor" umfasst insbesondere die Formulierung "mehrere Stellplatzsensoren". Das heißt also, dass in einer Ausführungsform mehrere Stellplatzsensoren vorgesehen sind. Diese mehreren Stellplatzsensoren sind beispielsweise identisch oder beispielsweise unterschiedlich ausgebildet. Ausführungen, die im Zusammenhang mit einem Stellplatzsensor gemacht sind, gelten analog für Ausführungsformen umfassend mehrere Stellplatzsensoren und umgekehrt.The wording “at least one parking space sensor” includes in particular the wording “several parking space sensors”. This means that several parking space sensors are provided in one embodiment. These multiple parking space sensors are, for example, identical or, for example, different. Versions that are made in connection with a parking space sensor apply analogously to embodiments comprising a plurality of parking space sensors and vice versa.

Gemäß einer Ausführungsform ist vorgesehen, dass der zumindest eine Stellplatzsensor als einer der folgenden Sensoren oder als eine Kombination der folgenden Sensoren ausgebildet ist: Ultraschallsensor, Radarsensor, Infrarotsensor, Magnetsensor, Radarsensor, Drucksensor, Lasersensor, Lidarsensor.According to one embodiment, it is provided that the at least one parking space sensor is designed as one of the following sensors or as a combination of the following sensors: ultrasonic sensor, radar sensor, infrared sensor, magnetic sensor, radar sensor, pressure sensor, laser sensor, lidar sensor.

Zum Beispiel sind mehrere Stellplatzsensoren vorgesehen, die als einer der vorstehend genannten Sensoren ausgebildet sind. Zum Beispiel sind ein Radarsensor und ein Magnetsensor vorgesehen. Zum Beispiel ist ein kombinierter Radar-/Magnet-Sensor vorgesehen. Das heißt allgemein, der zumindest ein Stellplatzsensor als eine Sensorkombination ausgebildet ist, die einen oder mehrere der vorstehend genannten Sensoren umfasst. Der zumindest eine Stellplatzsensor weist beispielsweise eine Funktionalität von einem oder von mehreren der vorstehend genannten Sensoren auf.For example, several parking space sensors are provided, which are designed as one of the sensors mentioned above. For example, a radar sensor and a magnetic sensor are provided. For example, a combined radar / magnetic sensor is provided. In general, this means that at least one parking space sensor is designed as a sensor combination that includes one or more of the aforementioned sensors. The at least one parking space sensor has, for example, functionality of one or more of the aforementioned sensors.

Ein Belegungszustand gibt insbesondere an, ob der Stellplatz belegt oder unbelegt ist. Auf einem belegten Stellplatz ist also insbesondere ein Kraftfahrzeug abgestellt. Auf einem unbelegten Stellplatz ist also insbesondere kein Kraftfahrzeug abgestellt. Ein unbelegter Stellplatz ist also frei von einem Kraftfahrzeug.An occupancy status indicates in particular whether the parking space is occupied or not. In particular, a motor vehicle is parked on an occupied parking space. In particular, no motor vehicle is parked on an unoccupied parking space. An unoccupied parking space is therefore free of a motor vehicle.

Nach einer Ausführungsform ist vorgesehen, dass ein einen Gehäusedeckel umfassendes Gehäuse vorgesehen ist, in welchem der zumindest eine Stellplatzsensor angeordnet ist.According to one embodiment, it is provided that a housing comprising a housing cover is provided, in which the at least one parking space sensor is arranged.

Dadurch wird insbesondere der technische Vorteil bewirkt, dass der zumindest eine Stellplatzsensor effizient gegen äußere Einflüsse geschützt werden kann. Solch äußere Einflüsse umfassen zum Beispiel Feuchtigkeit und/oder mechanische Belastungen.This has the technical advantage in particular that the at least one parking space sensor can be efficiently protected against external influences. Such external influences include, for example, moisture and / or mechanical loads.

Gemäß einer weiteren Ausführungsform ist vorgesehen, dass der erste Stromkreis einen mittels des Gehäusedeckels betätigbaren mechanischen Schalter umfasst, so dass der Schalter bei geschlossenem Gehäusedeckel geschlossen und bei geöffnetem Gehäusedeckel offen ist.According to a further embodiment it is provided that the first circuit comprises a mechanical switch which can be actuated by means of the housing cover, so that the switch is closed when the housing cover is closed and open when the housing cover is open.

Dadurch wird insbesondere der technische Vorteil bewirkt, dass ein Öffnen des Gehäusedeckels effizient erkannt werden kann, da das Öffnen des Gehäusedeckels für einen Diebstahl des Stellplatzsensors notwendig ist, um diesen aus dem Gehäuse zu entnehmen. Das heißt, dass ein Dieb, der den Stellplatzsensor stehlen will, zwangsläufig in der Regel den Gehäusedeckel öffnen muss. Dies wird gemäß dieser Ausführungsform effizient direkt erkannt. Das Öffnen des Gehäusedeckels bewirkt also ein Unterbrechen des ersten Stromkreises, so dass dann entsprechend das Signal über das Kommunikationsnetzwerk gesendet wird.In particular, this has the technical advantage that an opening of the housing cover can be detected efficiently, since the opening of the housing cover is necessary for theft of the parking space sensor in order to remove it from the housing. This means that a thief who wants to steal the parking space sensor usually has to open the housing cover. According to this embodiment, this is efficiently recognized directly. Opening the housing cover thus interrupts the first circuit, so that the signal is then sent over the communication network.

Der mechanische Schalter ist nach einer Ausführungsform als ein Magnetschalter ausgebildet.According to one embodiment, the mechanical switch is designed as a magnetic switch.

Gemäß einer weiteren Ausführungsform ist vorgesehen, dass der Gehäusedeckel einen elektrisch leitfähigen Gehäusedeckelabschnitt umfasst, wobei das Gehäuse einen elektrisch leitfähigen Gehäuseabschnitt umfasst, wobei bei geschlossenem Gehäusedeckel eine elektrisch leitfähige erste Verbindung zwischen dem elektrisch leitfähigen Gehäusedeckelabschnitt und dem elektrisch leitfähigen Gehäuseabschnitt gebildet ist, die bei geöffnetem Gehäusedeckel unterbrochen ist, wobei der erste Stromkreis die elektrisch leitfähige erste Verbindung umfasst.According to a further embodiment, it is provided that the housing cover comprises an electrically conductive housing cover section, the housing comprising an electrically conductive housing section, wherein when the housing cover is closed, an electrically conductive first connection between the electrically conductive housing cover section and the electrically conductive housing section is formed, which is opened Housing cover interrupted , wherein the first circuit comprises the electrically conductive first connection.

Dadurch wird insbesondere der technische Vorteil bewirkt, dass analog zur vorstehend beschriebenen Ausführungsform das Öffnen des Gehäusedeckels effizient erkannt oder detektiert werden kann. Die vorstehend gemachten Ausführungen gelten hier analog.In particular, this has the technical advantage that, analogously to the embodiment described above, the opening of the housing cover can be efficiently recognized or detected. The statements made above apply analogously here.

Nach einer Ausführungsform ist vorgesehen, dass ein Bodenkontakt auf einer Außenseite eines Gehäusebodens des Gehäuses angeordnet ist, der mit einem außerhalb des Gehäuses angeordneten Bodengegenkontakt eine elektrisch leitfähige zweite Verbindung bildet, so dass bei Verlagern des Gehäuses weg von dem Bodengegenkontakt die elektrisch leitfähige zweite Verbindung unterbrochen wird, wobei der erste Stromkreis die elektrisch leitfähige zweite Verbindung umfasst.According to one embodiment, it is provided that a bottom contact is arranged on an outside of a housing bottom of the housing, which forms an electrically conductive second connection with a bottom counter contact arranged outside the housing, so that when the housing is moved away from the bottom counter contact, the electrically conductive second connection is interrupted , wherein the first circuit comprises the electrically conductive second connection.

Dadurch wird insbesondere der technische Vorteil bewirkt, dass effizient erkannt oder detektiert werden kann, wenn das Gehäuse vom Boden entfernt wird. So ist also vorgesehen, dass der Gegenkontakt am Boden stationär angeordnet wird, wobei das Gehäuse mit seiner Bodenseite auf dem Bodengegenkontakt angeordnet ist. Wenn nun ein Dieb das Gehäuse aufnimmt, so wird dadurch der erste Stromkreis unterbrochen, was dann wiederum zu einem Senden des Signals führt.This has the particular technical advantage of being able to be efficiently recognized or detected when the housing is removed from the floor. Thus, it is provided that the counter contact is arranged stationary on the floor, the housing being arranged with its bottom side on the floor counter contact. If a thief takes up the housing, the first circuit is interrupted, which in turn leads to the signal being sent.

Nach einer Ausführungsform ist vorgesehen, dass die Detektionseinrichtung eine Strommesseinrichtung zum Messen eines durch den ersten Stromkreis fließenden elektrischen Stroms und/oder eine Spannungsmesseinrichtung zum Messen einer an dem zumindest einen Stellplatzsensor anliegenden elektrischen Spannung umfasst.According to one embodiment, it is provided that the detection device comprises a current measuring device for measuring an electrical current flowing through the first circuit and / or a voltage measuring device for measuring an electrical voltage applied to the at least one parking space sensor.

Dadurch wird insbesondere der technische Vorteil bewirkt, dass effizient bestimmt werden kann, ob der erste Stromkreis offen oder geschlossen ist. Denn sofern innerhalb des ersten Stromkreises kein elektrischer Strom mehr fließt, ist dies ein Zeichen dafür, dass der erste Stromkreis unterbrochen ist. Üblicherweise wird durch den ersten elektrischen Energiespeicher eine elektrische Spannung an den zumindest einen Stellplatzsensor angelegt, wobei diese Spannung nur dann messbar ist, wenn der erste Stromkreis geschlossen ist.This has the technical advantage in particular that it can be efficiently determined whether the first circuit is open or closed. Because if there is no more electrical current flowing within the first circuit, this is a sign that the first circuit is interrupted. An electrical voltage is usually generated by the first electrical energy store applied to the at least one parking space sensor, this voltage being measurable only when the first circuit is closed.

Die Detektionseinrichtung umfasst zum Beispiel eine Widerstandsmesseinrichtung zum Messen eines elektrischen Widerstands des ersten Stromkreises. Sofern der erste Stromkreis offen, also unterbrochen, ist, so würde eine entsprechende Widerstandmessung in der Regel einen Wert von unendlich ergeben.The detection device comprises, for example, a resistance measuring device for measuring an electrical resistance of the first circuit. If the first circuit is open, i.e. interrupted, a corresponding resistance measurement would usually result in a value of infinity.

Nach einer Ausführungsform ist vorgesehen, dass die Kommunikationsschnittstelle in dem zumindest einen Stellplatzsensor integriert ist.According to one embodiment, it is provided that the communication interface is integrated in the at least one parking space sensor.

Dadurch wird insbesondere der technische Vorteil bewirkt, dass bei einer Montage des Stellplatzsensors die Kommunikationsschnittstelle gleich mitmontiert werden kann. Dadurch wird zum Beispiel eine effiziente Montage bewirkt.This has the particular technical advantage that the communication interface can be installed at the same time when the parking space sensor is installed. This results in efficient assembly, for example.

Nach einer Ausführungsform ist vorgesehen, dass der zumindest eine Stellplatzsensor zusätzlich in dem zweiten Stromkreis geschaltet ist.According to one embodiment, it is provided that the at least one parking space sensor is additionally connected in the second circuit.

Dadurch wird insbesondere der technische Vorteil bewirkt, dass auch bei einer Unterbrechung des ersten Stromkreises der zumindest eine Stellplatzsensor mit elektrischer Energie versorgt werden kann. Dies ist zum Beispiel dann sinnvoll und vorteilhaft, wenn die Kommunikationsschnittstelle im Stellplatzsensor integriert ist.In particular, this has the technical advantage that even if the first circuit is interrupted, the at least one parking space sensor can be supplied with electrical energy. This is useful and advantageous, for example, if the communication interface is integrated in the parking space sensor.

Nach einer Ausführungsform ist vorgesehen, dass der zweite elektrische Energiespeicher in dem zumindest einen Stellplatzsensor integriert ist.According to one embodiment, it is provided that the second electrical energy store is integrated in the at least one parking space sensor.

Dadurch wird insbesondere der technische Vorteil bewirkt, dass bei einer Montage des Stellplatzsensors gleichzeitig der zweite elektrische Energiespeicher montiert wird. Dadurch wird somit eine effiziente Montage bewirkt.This has the particular technical advantage that when the parking space sensor is installed, the second electrical energy store is simultaneously installed. This results in efficient assembly.

Technische Funktionalitäten des Verfahrens ergeben sich analog aus entsprechenden technischen Funktionalitäten der Sensorvorrichtung und umgekehrt. Das heißt also insbesondere, dass sich entsprechende Verfahrensmerkmale aus entsprechenden Vorrichtungsmerkmalen und umgekehrt ergeben.Technical functionalities of the method result analogously from corresponding technical functionalities of the sensor device and vice versa. In particular, this means that corresponding process features result from corresponding device features and vice versa.

Nach einer Ausführungsform ist vorgesehen, dass die zumindest eine Sensorvorrichtung auf einem oder im Boden des zumindest einen Stellplatzes angeordnet ist.According to one embodiment, it is provided that the at least one sensor device is arranged on or in the floor of the at least one parking space.

Zum Beispiel ist im Boden des Stellplatzes eine Vertiefung gebildet, wobei die Sensorvorrichtung in der Vertiefung, insbesondere im Boden der Vertiefung, angeordnet ist.For example, a depression is formed in the bottom of the parking space, the sensor device being arranged in the depression, in particular in the bottom of the depression.

Ein elektrischer Energiespeicher im Sinne der vorliegenden Erfindung, also insbesondere der erste und/oder zweite elektrische Energiespeicher umfasst zum Beispiel eine oder mehrere Batterien und/oder einen oder mehrere Akkumulatoren und/oder einen oder mehrere Kondensatoren.An electrical energy store in the sense of the present invention, that is to say in particular the first and / or second electrical energy store, comprises, for example, one or more batteries and / or one or more accumulators and / or one or more capacitors.

Nach einer Ausführungsform ist der zumindest eine Stellplatzsensor energieautark ausgebildet. Das heißt also insbesondere, dass keine Stromkabel zur Sensorvorrichtung verlegt werden müssen.According to one embodiment, the at least one parking space sensor is designed to be energy self-sufficient. This means in particular that no power cables have to be laid to the sensor device.

Fig. 1 zeigt eine Sensorvorrichtung 101 zum Überwachen eines Belegungszustands eines Stellplatzes eines Parkplatzes für Kraftfahrzeuge. Fig. 1 shows a sensor device 101 for monitoring an occupancy state of a parking space of a parking lot for motor vehicles.

Die Sensorvorrichtung 101 umfasst einen Stellplatzsensor 103 zum Überwachen eine Belegungszustands eines Stellplatzes eines Parkplatzes. In einer nicht gezeigten Ausführungsform sind mehrere Stellplatzsensoren 103 vorgesehen.The sensor device 101 comprises a parking space sensor 103 for monitoring an occupancy state of a parking space of a parking lot. In an embodiment not shown, a plurality of parking space sensors 103 are provided.

Die Sensorvorrichtung 101 umfasst einen ersten elektrischen Energiespeicher 105 für eine elektrische Energieversorgung des Stellplatzsensors 103. Das heißt also, dass der erste elektrische Energiespeicher 105 den Stellplatzsensor 103 mit elektrischer Energie versorgt. Das heißt also insbesondere, dass eine elektrisch leitfähige Verbindung zwischen dem Stellplatzsensor 103 und dem ersten elektrischen Energiespeicher 105 gebildet ist.The sensor device 101 comprises a first electrical energy store 105 for an electrical energy supply of the parking space sensor 103. This means that the first electrical energy storage 105 supplies the parking space sensor 103 with electrical energy. This means in particular that an electrically conductive connection is formed between the parking space sensor 103 and the first electrical energy store 105.

Das heißt also, dass ein erster Stromkreis 107 gebildet ist, in welchem der Stellplatzsensor 103 und der erste elektrische Energiespeicher 105 geschaltet sind. Die Sensorvorrichtung 101 umfasst ferner eine Detektionseinrichtung 109 zum Detektieren einer Unterbrechung des ersten Stromkreises 107. Das heißt also insbesondere, dass die Detektionseinrichtung 109 ausgebildet ist, eine Unterbrechung des ersten Stromkreises 107 zu detektieren.This means that a first circuit 107 is formed, in which the parking space sensor 103 and the first electrical energy store 105 are connected. The sensor device 101 further comprises a detection device 109 for detecting an interruption of the first circuit 107. That means in particular that the detection device 109 is designed to detect an interruption of the first circuit 107.

Die Sensorvorrichtung 101 umfasst ferner eine Kommunikationsschnittstelle 111 sowie einen zweiten elektrischen Energiespeicher 113. Der zweite elektrische Energiespeicher 113 versorgt die Kommunikationsschnittstelle 111 mit elektrischer Energie. Das heißt also insbesondere, dass die Kommunikationsschnittstelle 111 und der zweite elektrische Energiespeicher 113 elektrisch leitfähig verbunden sind. Das heißt also insbesondere, dass ein zweiter Stromkreis 115 gebildet ist, in welchem die Kommunikationsschnittstelle 111 und der zweite elektrische Energiespeicher 113 geschaltet sind.The sensor device 101 further comprises a communication interface 111 and a second electrical energy store 113. The second electrical energy store 113 supplies the communication interface 111 with electrical energy. This means in particular that the communication interface 111 and the second electrical energy store 113 are electrically conductively connected. That means in particular that a second circuit 115 is formed, in which the communication interface 111 and the second electrical energy store 113 are connected.

Sofern mittels der Detektionseinrichtung 109 eine Unterbrechung des ersten Stromkreises 107 detektiert wird, so sendet die Kommunikationsschnittstelle 111 über ein Kommunikationsnetzwerk ein Signal, welches die Information umfasst, dass der erste Stromkreis 107 unterbrochen ist.If an interruption of the first circuit 107 is detected by means of the detection device 109, the communication interface 111 sends a signal via a communication network, which includes the information that the first circuit 107 is interrupted.

Zum Beispiel ist ein Gehäuse vorgesehen, welches einen Gehäusedeckel umfasst, wobei der Stellplatzsensor 103 in dem Gehäuse angeordnet ist. Gemäß dieser Ausführungsform ist zum Beispiel vorgesehen, dass ein Öffnen des Gehäusedeckels zu einer Unterbrechung des ersten Stromkreises 107 führt. Somit wird also das Öffnen des Gehäusedeckels effizient detektiert, wobei dann diese Information als Signal über das Kommunikationsnetzwerk versendet wird.For example, a housing is provided which comprises a housing cover, the parking space sensor 103 being arranged in the housing. According to this embodiment, it is provided, for example, that opening the housing cover leads to an interruption of the first circuit 107. The opening of the housing cover is thus efficiently detected, and this information is then sent as a signal via the communication network.

Zum Beispiel ist vorgesehen, dass ein Bodenkontakt auf einer Außenseite eines Gehäusebodens des Gehäuses angeordnet ist. Am Boden des Stellplatzes oder zum Beispiel in einer Vertiefung eines Bodens eines Stellplatzes ist ein Bodengegenkontakt angeordnet. Die Sensorvorrichtung wird im Betrieb des Parkplatzes mit der Außenseite des Gehäusebodens auf den Bodengegenkontakt angeordnet. Das heißt also, dass im angeordneten oder montierten Zustand der Bodenkontakt mit dem Bodengegenkontakt eine elektrisch leitfähige zweite Verbindung bildet.For example, it is provided that a ground contact is arranged on an outside of a housing bottom of the housing. A ground counter-contact is arranged on the floor of the parking space or, for example, in a depression in the floor of a parking space. The sensor device is arranged in the operation of the parking lot with the outside of the housing base on the ground counter contact. So that means that in the arranged or assembled state the ground contact forms an electrically conductive second connection with the ground counter contact.

Wenn eine Person das Gehäuse vom Boden oder aus der Vertiefung des Bodens des Stellplatzes entfernt, so wird diese zweite Verbindung getrennt werden. Es ist vorgesehen, dass der erste Stromkreis 107 die elektrisch leitfähige zweite Verbindung umfasst. Das heißt also, dass bei einem Trennen der zweiten Verbindung der erste Stromkreis 107 unterbrochen wird, was durch die Detektionseinrichtung 109 detektiert wird, so dass dann entsprechend ein Signal mittels der Kommunikationsschnittstelle 111 ausgesendet wird.If a person removes the housing from the floor or from the depression of the floor of the parking space, this second connection will be separated. It is provided that the first circuit 107 comprises the electrically conductive second connection. This means that when the second connection is disconnected, the first circuit 107 is interrupted, which is detected by the detection device 109, so that a signal is then correspondingly transmitted by means of the communication interface 111.

Fig. 2 zeigt ein Ablaufdiagramm eines Verfahrens zum Überwachen eines Belegungszustands eines Stellplatzes eines Parkplatzes für Kraftfahrzeuge unter Verwendung einer Sensorvorrichtung, wie sie vor- oder nachstehend beschrieben ist. Fig. 2 shows a flowchart of a method for monitoring an occupancy state of a parking space of a parking lot for motor vehicles using a sensor device as described above or below.

Das Verfahren umfasst die folgenden Schritte:

  • Überwachen 201 des Belegungszustands des Stellplatzes mittels des zumindest einen Stellplatzsensors,
  • bei Detektion 203 einer Unterbrechung des ersten Stromkreises mittels der Detektionseinrichtung Senden 205 eines Signals mittels der Kommunikationsschnittstelle über das Kommunikationsnetzwerk, wobei das Signal die Information umfasst, dass der erste Stromkreis unterbrochen ist.
The process includes the following steps:
  • Monitoring 201 the occupancy status of the parking space by means of the at least one parking space sensor,
  • upon detection 203 of an interruption of the first circuit by means of the detection device, sending 205 a signal by means of the communication interface via the communication network, the signal comprising the information that the first circuit is interrupted.

Fig. 3 zeigt einen Parkplatz 301 für Kraftfahrzeuge. Der Parkplatz 301 umfasst zumindest einen Stellplatz 303. Fig. 3 shows a parking lot 301 for motor vehicles. The parking lot 301 comprises at least one parking space 303.

Im Boden 305 des Stellplatzes 303 ist die Sensorvorrichtung 101 gemäß Fig. 1 angeordnet. Der Übersicht halber ist lediglich ein Viereck mit dem Bezugszeichen 101 als Platzhalter für die einzelnen in Fig. 1 dargestellten Elemente gezeichnet.In the floor 305 of the parking space 303, the sensor device 101 according to Fig. 1 arranged. For the sake of clarity, there is only a square with the reference symbol 101 as a placeholder for the individual in FIG Fig. 1 elements shown.

Der Parkplatz 301 umfasst noch weitere Stellplätze, die analog zu der in Fig. 3 gezeigten Anordnung ebenfalls mit entsprechenden Sensorvorrichtungen versehen sind.Parking lot 301 also includes other parking spaces that are analogous to the one in Fig. 3 shown arrangement are also provided with appropriate sensor devices.

Sofern die Sensorvorrichtung im oder am Boden des Stellplatzes angeordnet ist, kann die Sensorvorrichtung insbesondere auch als eine Bodensensorvorrichtung bezeichnet werden.If the sensor device is arranged in or on the floor of the parking space, the sensor device can in particular also be referred to as a floor sensor device.

Die Erfindung basiert also insbesondere auf dem Gedanken, das Öffnen oder Unterbrechen eines Stromkreises, in welchem ein Stellplatzsensor und ein den Stellplatzsensor versorgender elektrischer Energiespeicher geschaltet sind, als Kriterium dafür zu verwenden, dass ein unerlaubter Eingriff auf den Stellplatzsensor stattfindet. Das heißt also insbesondere, dass, wenn der Stromkreis geöffnet wird, der Stellplatzsensor zum Beispiel unter Verwendung einer gespeicherten Restenergie noch ein Signal sendet. Die gespeicherte Restenergie ist zum Beispiel in einer Batterie oder in einem Kondensator gespeichert, also insbesondere in dem zweiten Energiespeicher.The invention is based in particular on the idea of opening or interrupting a circuit in which a parking space sensor and an electrical energy store supplying the parking space sensor are used as a criterion for an unauthorized intervention on the parking space sensor. This means in particular that when the circuit is opened, the parking space sensor still sends a signal, for example using a stored residual energy. The stored residual energy is stored, for example, in a battery or in a capacitor, in particular in the second energy store.

Ausgelöst wird dieser Mechanismus (also das Senden des Signals durch ein Trennen des Stromkreises) zum Beispiel durch ein Öffnen eines Gehäusedeckels und/oder eines Gehäuses.This mechanism is triggered (that is, the transmission of the signal by disconnecting the circuit), for example by opening a housing cover and / or a housing.

Zum Beispiel wird der Mechanismus durch ein Anheben des Gehäusebodens durch Auslösen eines Boden(gegen)kontakts ausgelöst.For example, the mechanism is triggered by lifting the housing base by triggering a base (against) contact.

Ein wesentlicher Vorteil ist, dass in Echtzeit ein Signal über das Kommunikationsnetzwerk gesendet wird, welches die Information umfasst, dass der erste Stromkreis unterbrochen ist, also die Information umfasst, dass ein unerlaubter Eingriff auf den Stellplatzsensor vorgenommen wird.A major advantage is that a signal is sent in real time via the communication network, which includes the information that the first circuit is interrupted, that is, the information that an unauthorized intervention on the parking space sensor is undertaken.

Ansprechend auf einen Empfang des Signals können dann zum Beispiel von einem Parkplatzverwaltungssystem Aktionen ausgelöst oder durchgeführt werden. Solche Aktionen umfassen zum Beispiel ein Alarmieren von Polizei.In response to receipt of the signal, actions can then be triggered or carried out, for example, by a parking lot management system. Such actions include, for example, alerting the police.
