Embodiment Construction

[0034] figure 1 An embodiment of the device according to the invention is shown. Device 10 is shown. Device 10 has a sensor unit 20 and a processing unit 30 . The sensor unit 20 is connected to the processing unit 30 in such a way that the measured values ​​detected by the sensor unit 20 can be retrieved by the processing unit 30 . For this purpose, the connection can be configured both as a wired connection and as a wireless one.

[0035] Device 10 can be designed, for example, in such a way that it is used to determine the occupancy state of a parking space of a parking space. For this purpose, the sensor unit 20 has, for example, a magnetic field sensor, wherein the processing unit 30 is provided to determine the occupancy state of the parking space using the measured magnetic field values ​​detected by the magnetic field sensor.

Abstract

The invention relates to a device (10) comprising a sensor unit (20) and a processing unit (30), wherein the sensor unit (20) is configured to detect at least one measurement value (22) at a predefined point in time, One aspect of the invention is that the processing unit (30) is configured to carry out self-calibration of the device (10) on the basis of the detected measurement value (22). The invention further relates to a method for self-calibration of a device (10) according to the invention.

Description

Background technique [0001] The invention starts with a device having a sensor unit and a processing unit, wherein the sensor unit is provided to detect at least one measured value at a predetermined instant. [0002] The device can be designed, for example, in such a way that it is used to determine the occupancy status of a parking space of a parking space. For this purpose, the sensor unit has, for example, a magnetic field sensor, wherein the processing unit is provided to determine the occupancy state of the parking space using the measured magnetic field values ​​detected by the magnetic field sensor. [0003] A typical problem with such devices is that the measurement conditions may change over time, for example because the vehicle is parked in an adjacent parking space, or because the sensor unit has drift. As a result, the determination of the occupancy state of the parking space may be distorted or erroneous. [0004] The invention furthermore relates to a method f...
