Description

The invention relates to a data processing device for an (off-street) parking system. Furthermore, the invention relates to an (off-street) parking system and a method. Parking systems with at least one parking device are known from the prior art. A parking device is, in particular, a parking garage or a parking lot. Such parking systems are also referred to as off-street parking systems or facilities. Such a parking system typically has one or more access devices at a corresponding number of passageways to and/or from a parking facility. For example, an access device may be equipped with a locking mechanism, such as a barrier with a pivoting arm. Such an access device primarily controls or directs a vehicle's passage through a passageway where the access device is located, from a first area to another area. A parking system may include at least one access device to control a vehicle's passage from an uncontrolled area, such as a (public) road, into a controlled area, such as the parking area or parking facility. In other words, entry into the parking facility can be controlled by an access device at an entrance to the parking system. Alternatively or additionally, a parking system may include at least one access device to control a vehicle's passage from the controlled area into the uncontrolled area. to control the controlled area. In other words, the exit of a vehicle from a parking facility can be controlled by an access device. An access device with a barrier or an access device without a barrier (also referred to as a free-flow system or free-flow access device) can be arranged at an entrance and/or exit. The entrance and/or exit can be structurally separated, for example, with separate lanes for entry and exit and separate access devices for each, or combined, for example, with an entrance and exit sharing a common lane and a common access device. Furthermore, several lanes in one direction can run parallel to each other at an entrance and/or exit, particularly with and without physical separation of the lanes. With known access control systems, entry into a parking facility is granted after a parking ticket, such as a short-term parking ticket, has been issued, based on a user action. The short-term parking ticket, particularly a paper ticket, is then paid for by the user at a machine at the end of the parking period and checked at the exit by a validator device of the access control system. If the check is successful, passage through the access point (in this case, exit) is authorized by a release module. However, if the validator device determines that the ticket has not yet been paid for, for example, or that payment was made too long ago, the access control system remains closed, and passage is blocked. In other words, passage through the access point is blocked by a release module. A constant concern with (off-street) parking systems is improving user comfort. In particular, manual user actions are considered user-unfriendly. Current technology already exists for parking systems that can reduce the required user actions. Parking systems are known in which a license plate recognition device is provided at each passage (in particular, at each passage), comprising at least one camera. The at least one camera of a license plate recognition device is configured to capture image data of the license plate of a vehicle passing through or driving through the respective passage. This includes, in particular, capturing the aforementioned image data before the vehicle passes through the passage. The license plate recognition device can include a camera and an image processing module connected to the camera. The image processing module can be configured to determine a license plate sequence from the captured image data. Such a license plate recognition device (with camera and image processing module) is also referred to as an LPR (License Plate Recognition) device. In an LPR license plate recognition device, the image of the vehicle license plate captured by the camera is evaluated by the image processing module, particularly using OCR (Optical Character Recognition), to determine the license plate sequence. The license plate chain represents a string of characters which the license plate identification device determines from the camera image or the camera's image data and which ideally is the string of characters that corresponds to the license plate chain on the license plate that is attached to the vehicle and depicted in the captured image data. In particular, in addition to image data, the respective license plate recognition device can also determine the time of passage (especially an entry or exit time). A data processing device may be installed to evaluate the aforementioned data. For example, the data processing device may be configured to determine the parking duration from the difference between the entry and exit times. The same license plate number or the same vehicle.
