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

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 subject matter of the independent claims. Advantageous embodiments of the invention are the subject of each dependent subclaims.
Nach einem Aspekt wird eine Sensorvorrichtung zum Überwachen eines Belegungszustands eines Stellplatzes eines Parkplatzes für Kraftfahrzeuge bereitgestellt, umfassend: In one aspect, there is provided a sensor apparatus for monitoring occupancy status of a parking space for a motor vehicle, comprising:
- zumindest einen Stellplatzsensor zum Überwachen eines Belegungszustands eines Stellplatzes eines Parkplatzes,  at least one parking space sensor for monitoring an occupancy state of a parking space of a parking space,
- einen ersten elektrischen Energiespeicher für eine elektrische Energieversorgung des zumindest einen Stellplatzsensors,  a first electrical energy store for an electrical energy supply of the at least one parking space sensor,
- wobei ein erster Stromkreis gebildet ist, in welchem der zumindest eine Stellplatzsensor und der erste elektrische Energiespeicher geschaltet sind, - Wherein a first circuit is formed, in which the at least one parking space sensor and the first electrical energy storage are connected,
- eine Detektionseinrichtung zum Detektieren einer Unterbrechung des ersten Stromkreises, a detection device for detecting an interruption of the first circuit,
- eine in einen zweiten Stromkreis geschaltete Kommunikationsschnittstelle zum Senden eines Signals über ein Kommunikationsnetzwerk bei einer de- tektierten Unterbrechung des ersten Stromkreises, wobei das Signal die Information umfasst, dass der erste Stromkreis unterbrochen ist,  a communication interface connected in 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,
- wobei in dem zweiten Stromkreis ein zweiter elektrischer Energiespeicher für eine elektrische Energieversorgung der Kommunikationsschnittstelle geschaltet ist.  - Wherein in the second circuit, a second electrical energy storage for an electrical power supply of the communication interface is connected.
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: According to a further aspect, there is provided a method of monitoring occupancy state of a parking space of a parking lot for motor vehicles using the sensor device according to the invention, comprising the following steps:
- Überwachen des Belegungszustands des Stellplatzes mittels des zumindest einen Stellplatzsensors, - bei Detektion einer Unterbrechung des ersten Stromkreises mittels der Detek- tionseinrichtung Senden eines Signals mittels der Kommunikationsschnittstelle über das Kommunikationsnetzwerk, wobei das Signal die Information um- fasst, dass der erste Stromkreis unterbrochen ist. Monitoring the occupancy state 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 transmitting a signal by means of the communication interface via the communication network, wherein the signal comprises 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 yet another aspect, a parking space for motor vehicles is provided, wherein the parking space comprises 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 by emitting a signal via a communication network when a disconnection of the first circuit is detected, the signal comprising the information that the first circuit is interrupted. As a result, it can advantageously be communicated efficiently via the communication network that an inadmissible intervention has been made on the sensor device. Because interrupting 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 communications network, for example, an operator of the parking lot can take efficient countermeasures. For example, he can alert the police or a security company who is looking directly at the site. If necessary, a thief can still be caught in time, which would ultimately have prevented the theft of the sensor device. But at least a theft of the sensor device is difficult.
Insbesondere wird der technische Vorteil bewirkt, dass ein Diebstahl respektive ein unerlaubter Eingriff effizient detektiert werden kann. In particular, the technical advantage is achieved that theft or 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. 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. Thus, in particular, the technical advantage is brought about that the information that an unauthorized intervention has been made on the sensor device is also provided remotely from the sensor device so that corresponding countermeasures can then be taken. The inventive concept also has the advantage that complex and complex and expensive monitoring 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, wherein the detection of an interruption of the first circuit is an easy way of detecting an unauthorized intervention, for example with a video camera, whose video data is usually complex only by means of an image analysis must be evaluated or manually controlled by a human. Whether a circuit is closed or interrupted, can be easily measured and thus determine.
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 phrase "at least one parking space sensor" includes in particular the formulation "multiple parking space sensors". This means that in one embodiment several parking space sensors are provided. These multiple parking space sensors are, for example, identical or designed differently, for example. Embodiments 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 configured 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 Ra- dar-/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 aforementioned sensors. For example, a radar sensor and a magnetic sensor are provided. For example, a combined radar / magnetic sensor is provided. This generally means that at least one parking space sensor is designed as a sensor combination comprising one or more of the aforementioned sensors. The at least one parking space sensor, for example, has a functionality of one or more of the aforementioned sensors.
Ein Belegungszustand gibt insbesondere an, ob der Stellplatz belegt oder unbe- legt ist. Auf einem belegten Stellplatz ist also insbesondere ein Kraftfahrzeug ab- gestellt. 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 occupied. In particular, a motor vehicle is required on an occupied parking space. posed. In particular, no motor vehicle is parked on an unoccupied parking space. An empty 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, provision is made for a housing comprising a housing cover to be 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. As a result, in particular the technical advantage is achieved 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 stress.
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.

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. As a result, the technical advantage in particular that an opening of the housing cover can be detected efficiently, since the opening of the housing cover for theft of the parking space sensor is necessary to remove it from the housing. This means that a thief who wants to steal the parking space sensor, inevitably usually has to open the housing cover. This is efficiently recognized directly according to this embodiment.

Die Erfindung basiert also insbesondere auf dem Gedanken, das Öffnen oder Unterbrechen eines Stromkreises, in welchem ein Stellplatzsensor und ein denThe invention is thus based in particular on the idea of opening or interrupting a circuit in which a parking space sensor and a
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 gespei- cherten 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. Parking space sensor supplying electrical energy storage are connected to use as a criterion that an unauthorized intervention takes place on the parking space sensor. This means in particular that when the circuit is opened, the parking space sensor, for example, still sends a signal using a stored residual energy. The stored residual energy is stored, for example, in a battery or in a capacitor, that is to say 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 (ie the transmission of the signal by disconnecting the circuit) is triggered, 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 raising the housing bottom by triggering a bottom (counter) 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 significant advantage is that in real time a signal is sent via the communication network, which includes the information that the first circuit is interrupted, that is, the information that an unauthorized intervention is made on the parking space sensor.
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 may be initiated or performed by, for example, a parking management system. Such actions include, for example, alerting police.
