Description

  • State of the art
  • The invention is based on a device for monitoring a parking state of a parking space, comprising a processing unit and a first, wireless communication unit, which is configured to communicate with a first external unit in a first frequency range.
  • Such a device is for example in the published patent application EP 2015257 A1 disclosed. In this case, authentication data are sent from a vehicle to a parking sensor which monitors a parking space. The parking sensor then forwards the authentication data and additional, parking sensor-specific data to a central unit. In the central unit, the authentication data and the parking sensor-specific data are then evaluated to infer whether the vehicle is authorized to park in the parking lot.
  • The invention also relates to a method for operating such a device.
  • Disclosure of the invention
  • The invention is based on a device for monitoring a parking state of a parking space, comprising a processing unit and a first, wireless communication unit, which is configured to communicate with a first external unit in a first frequency range. The gist of the invention is that the apparatus comprises a second wireless communication unit which is adapted to communicate with a second external unit in a second frequency range which is different from the first frequency range. In addition, the processing unit is configured to receive first authentication data of the first unit by means of the first communication unit and to compare it with second, stored authentication data. Furthermore, the processing unit is set up to emit a signal by means of the second communication unit in the event of inequality of the first and the second authentication data, which signalises a false parker. It is advantageous here that two different frequency ranges are used for communication. These can be adjusted according to the prevailing needs. Thus, for example, for communication with a nearby user, a frequency range can be selected in which the range of the signals is low and thus only a small amount of energy is needed. For communication with a remote server, however, for example, another frequency range can be selected, which allows the widest possible range. A further advantage is that the authentication is carried out in the device itself and thus only in the case of a recognized wrong parker, the second communication unit must be used to send out a corresponding signal. This in turn can be saved energy.
  • An advantageous embodiment of the invention provides that the device has a radar sensor, wherein the radar sensor has an antenna. In addition, the first communication unit is set up to communicate with the first external unit by means of the antenna.
  • It is advantageous here that the first communication unit can use the antenna of the radar sensor. As a result, the first communication unit does not require its own antenna, whereby on the one hand space can be saved and on the other hand production costs for the device can be reduced.
  • According to an advantageous embodiment of the invention it is provided that the device comprises an antenna switch, which is arranged between antenna, radar sensor and first communication unit. In addition, the processing unit is configured to control the antenna switch such that either the radar sensor or the first communication unit is connected to the antenna.
  • It is advantageous here that this allows a simple configuration in order to make the antenna usable both for the radar sensor and for the first communication unit. As a result, the first communication unit and the radar sensor can not interfere with each other, since only one of the two components is always connected to the antenna and can use it at the same time.
  • A further advantageous embodiment of the invention provides that the processing unit is set up to check, in particular by means of a radar sensor, whether the parking space is occupied and in this case to set the first communication unit in a transmit and receive mode. The advantage here is that the first communication unit is turned on only when needed, so if someone has parked in the parking lot and authorization is therefore desirable. This can save energy.
  • According to an advantageous embodiment of the invention, it is provided that the first frequency range is between 2.4 and 2.486 GHz or also 5.725 and 5.875 GHz.
  • It is advantageous here that this frequency range allows a range of the signal transmission which is sufficient for the relatively short distance between the first communication unit of the device and the first external unit, wherein the power consumption can be kept very low.
  • According to a further advantageous embodiment of the invention, it is provided that the second frequency range is between 433 and 435 MHz, 863 and 870 MHz or 902 and 928 MHz.
  • It is advantageous in this case that this frequency range allows a very long range and thus the signal transmission from the second communication unit to a far away second external unit, such as a gateway or a server, can be performed reliably.
  • The invention also relates to a method for operating a device for monitoring a parking condition of a parking space, comprising the following method steps:
  1. a. Receiving first authentication data of a first external unit by means of a first wireless communication unit of the device,
  2. b. Comparing the first authentication data with second stored authentication data by means of a processing unit of the device,
  3. c. Transmitting a signal by means of a second communication unit of the device if the first and second authentication data do not match, the signal signaling a false parker, and wherein the first communication unit and the second communication unit communicate in different frequency ranges.
  • It is advantageous here that two different frequency ranges are used for communication. These can be adjusted according to the prevailing needs. Thus, for example, for communication with a nearby user, a frequency range can be selected in which the range of the signals is low and thus only a small amount of energy is needed. For communication with a remote server, however, for example, another frequency range can be selected, which allows the widest possible range. A further advantage is that the authentication is carried out in the device itself and thus only in the case of a recognized wrong parker, the second communication unit must be used to send out a corresponding signal. This in turn can be saved energy.
  • In an advantageous embodiment of the method according to the invention, it is provided that prior to method step a, a method step d takes place in which, in particular by means of a radar sensor of the device, it is checked whether the parking space is occupied and in this case after method step d and before the method step a is a process step e, in which the first communication unit is set in a transmit and receive mode. The advantage here is that the first communication unit is turned on only when needed, so if someone has parked in the parking lot and authorization is therefore desirable. This can save energy.
  • According to an advantageous embodiment of the method according to the invention, it is provided that after method step b, a method step f takes place, in which the first communication unit is put into a sleep state. It is advantageous here that after checking whether the user of the parking space is authorized to park in the parking lot, the first communication unit can be put into a sleep state, which in turn can save energy.
  • According to a further advantageous embodiment of the method according to the invention, it is provided that a method step g takes place before method step a, in which the second authentication data are received and stored by the device.
  • It is advantageous here that the second authentication data can be updated in order to deposit, for example, in the device that another user is authorized to occupy the parking space.
  • According to a further advantageous embodiment of the method according to the invention, it is provided that the first communication unit communicates in a first frequency range between 2.4 and 2.486 GHz or also 5.725 and 5.875 GHz.
  • It is advantageous here that this frequency range allows a range of the signal transmission which is sufficient for the relatively short distance between the first communication unit of the device and the first external unit, wherein the power consumption can be kept very low.
  • According to a further advantageous embodiment of the method according to the invention it is provided that the second communication unit in a second frequency range between 433 and 435 MHz, 863 and 870MHz or 902 and 928 MHz.
  • The advantage here is that the advantage here is that this frequency range allows a very large range and thus the signal transmission from the second communication unit to a far away second external unit, such as a gateway or a server can be reliably performed.

  • Description of exemplary embodiments
  • 1 shows an embodiment of a device for monitoring an occupancy state of a parking lot.
  • Shown is a device 10 which is a processing unit 20 having. The processing unit 20 may be, for example, a microcontroller. In addition, the device 10 a first wireless communication unit 31 on. The first communication unit 31 is configured to have at least a first external unit 41 to communicate. The communication takes place in a first frequency range. The first communication unit 31 is on the one hand with the processing unit 20 connected and on the other hand via an antenna switch 16 with an antenna 14 connectable. As a result, for example, first authentication data 51 from the first external unit 41 over the antenna 14 , the antenna switch 16 and the first communication unit 31 through the processing unit 20 be received. The first communication unit 31 may for example be a Bluetooth unit, the first frequency range may then be between 2.4 and 2.486 GHz. However, the first frequency range may also be, for example, between 2.4 and 2.486 GHz or even 5.725 and 5.875 GHz, wherein the antenna 14 then designed as a dual antenna. The first external unit 41 For example, it may be a mobile telephone of a vehicle driver or even a vehicle itself, which then likewise has a corresponding communication unit in order to communicate with the first communication unit in the first frequency range 31 to communicate. The first authentication data 51 Then, for example, the MAC address of the Bluetooth module of the first external unit 41 be. The device 10 also has a radar sensor 12 on, which also via the antenna switch 16 with the antenna 14 is connectable and which is adapted to determine radar measurements. The processing unit 20 is also with the radar sensor 12 connected and adapted to monitor based on the radar measurements a parking condition of the parking lot. The processing unit 20 is also with the antenna switch 16 connected and configured to the antenna switch 16 to control such that either the radar sensor 12 or the first communication unit 31 via the antenna switch 16 with the antenna 14 connected is.
  • Furthermore, the device 10 a second, wireless communication unit 32 on. The second communication unit 32 is in turn with the processing unit 20 connected and set up with a second external unit 42 to communicate in a second frequency range. The second communication unit 32 is in particular a wireless module ISM (Industrial, Scientific and Medical Band) and uses as a second frequency range, for example, one of the bands from 433 to 435 MHz, from 863 to 870 MHz or from 902 to 928 MHz. Thus, the first and second frequency ranges are different from one another, wherein in particular the first frequency range has higher frequencies than the second frequency range. The processing unit 20 is also set up by the first external unit 41 received first authentication data 51 with at least second, stored authentication data 52 to compare. The second authentication data 52 for example, from the second external unit 42 by means of the second communication unit 32 to the processing unit 20 sent and stored in their internal memory, not shown. Alternatively, however, also the first communication unit 41 in a so-called pairings mode, in which it is possible authentication data of the first external unit 41 as second authentication data 52 save. For example, the MAC address of the Bluetooth module thus becomes the first external unit 41 as second authentication data 52 deposited. Voices the first authentication data 51 and the at least second authentication data 52 do not match, is the processing unit 20 set up a signal 60 by means of the second communication unit 32 to the second external unit 42 to send. This signal 60 clarifies an unauthorized user and thus a wrong parker.
  • Instead of the radar sensor 12 It would also be conceivable that another type of sensor is used to monitor the occupancy status of the parking lot. This could for example be a magnetic sensor, an ultrasonic sensor or a Be infrared sensor. For example, the first frequency range can also serve to enable a quick firmware update of the sensor. This saves energy, because the data throughput in the first frequency range due to the small distance between the first communication unit 31 and first external unit 41 may be higher than in the second frequency range.
  • Such a device according to the invention 10 is suitable, for example, for a permanent parking space in a parking garage on which only one user is authorized to park. However, the device is 10 for example, also be used in a resident parking, in addition to the second authentication data 52 then, for each additional resident, further authentication data in the device 10 are stored. Upon receipt of the first authentication data 51 These are then compared with all stored authentication data and if none of the stored authentication data with the first authentication data 51 match the signal 60 sent out. The same applies, for example, to a parking space in which several users have a parking authorization.
  • 2 shows an embodiment of an inventive method of operating a device 10 for monitoring a parking condition of a parking lot.
  • First, in a process step a, first authentication data are obtained 51 a first, external unit 41 by means of a first, wireless communication unit 31 the device 10 received in a first frequency range.
  • In a method step b, the first authentication data are then produced 51 at least with the second, in the device 10 stored authentication data 52 by means of a processing unit 20 the device 10 compared.
  • Voices the first authentication data 51 not with the at least second authentication data 52 coincide, a method step c is performed, in which a signal 60 by means of a second communication unit 32 the device 10 is emitted in a second frequency range. The signal 60 this signals a wrong parker. The first frequency range also differs from the second frequency range. In particular, the first frequency range has higher frequencies than the second frequency range. For example, the first frequency range may be between 2.4 and 2.486 GHz, whereas the second frequency range is between 433 and 435 MHz, 863 and 870 MHz or 902 and 928 MHz. However, the first frequency range can also be, for example, between 2.4 and 2.486 GHz or even 5.725 and 5.875 GHz.
  • Optionally, prior to method step a, a method step d continues. In this case, it is checked in method step d whether the parking space is occupied. This is done in particular by means of a radar sensor 12 the device 10 checked. If the parking space is occupied, a method step e, in which the first communication unit 31 is put in a transmit and receive mode. In this transmit and receive mode, which is also referred to as advertising mode, sends the first communication unit 31 at regular intervals an indication signal, which from a first external unit 41 can be received, and then waits for a connection request. Based on the hint signal becomes the first external unit 41 to the first communication unit 31 attentive and can then connect to it to exchange data. Between process steps e and f may still be an unillustrated process step, in which the antenna switch 16 from the processing unit 20 is controlled such that the radar sensor 12 from the antenna 14 separated and for the first communication unit 31 with the antenna 14 is connected.
  • Furthermore, optionally after method step b, a method step f starts, in which the first communication unit 31 is put back into a sleep state. In addition, here another unillustrated process step can take place, in which the antenna switch 16 is again controlled such that the radar sensor 12 instead of the first communication unit 31 with the antenna 14 connected is.
  • In addition, optionally before the method step a, a method step g, in which the second authentication data 52 from the device 10 be received and stored. In this case, the second authentication data 52 by means of the first communication unit 31 or also by means of the second communication unit 32 be received. Optionally, in a method step, not shown, also a firmware update of the sensor 12 done by means of the first communication unit 31 Firmware data are received.
