Abstract

The means for controlling the access rights in the access area comprise guiding means for forming an access channel for separating persons or objects, in which access channel the blocking means and/or the signaling means define an access threshold. A door controller with a bluetooth radio interface enables reading of the access rights from the mobile data carrier, which releases the blocking means and/or the signaling means and thus enables a separate passing of the access threshold when the authentication of the access rights is positive. The entry channel is here provided with a polyphase antenna group whose transmit/receive antennas are steered by the bluetooth transceiver module via an antenna feed network such that at least two antenna lobes are formed, which are at different distances from the entry threshold as seen in the entry direction. The door control (9) continuously transmits short signals (broadcast events) during idle operation via an antenna lobe (6) which is located at a large distance from the entrance threshold (3) as seen in the entrance direction and activates the bluetooth radio interface of the approaching mobile data carrier (1). Each data carrier (1) having access rights is provided with a unique rights identification (UID or rights ID) which can be read by means of a ticket application which can be activated by means of a Bluetooth interface. The door controller (9) reads the authority identification via an antenna lobe (5) at a short distance from the entrance threshold (3) and measures the received field strength (RSSI) of the signal transmitted by the data carrier (1) on the antenna lobe (5). When the evaluation of the received field strength (RSSI) is affirmative and the authentication of the authority (UID) is affirmative, the access controller (9) generates a release signal for the blocking means and/or the signaling means (12, 13).

Description

Device for controlling access rights Technical Field Ticket systems are known in different applications, wherein a distinction is made between applications with access control (gating area) and systems without access control (inside/outside, be in/Be out). The two methods may also be combined. The rights to enable entry for a particular service and/or location are also referred to as tickets, wherein the entry may be specific in time, location or value and personal (non-transportable) or transportable. The ticket may typically be stored on a medium and/or as a right in a database. The present invention relates to applications requiring at least partial access control, for example in the case of ski lifts, but is not limited to such applications. For ski lifts, the entrance is usually organized into one or more access channels by means of mechanical guides, wherein a reading device for the ticket is provided in each access channel. The reading device detects a ticket of an entering person, checks the entering authority and outputs a release signal to a blocking part located in the entering passage after the authentication is affirmative. The blocking portion may be a cross-shaped swing door, a pivot door, an optical signal, or the like. Background In the first generation of such ski ticket systems, bar code tickets or magnetic cards were used as ticket media, and the reading device was correspondingly a plug-in reader for bar codes or magnetic cards. In order to eliminate the maintenance requirement of mechanical reading devices, these are then replaced by contactless RFID transponders, wherein LF (125 kHz), HF (13.56 MHz) are known as RFID technology and in the latest systems UHF (900 MHz) is also known as RFID technology. A general disadvantage of a ticket system with ticket media is that it is also necessary to provide ticket media and a suitable ticket printer in order to organize ticket sales. Since most customers/access rights people now already possess smartphones, it is advantageous to use smartphones as bill media. This has been used for airport boarding where boarding notes are stored in the form of bar codes in smartphones. However, this approach is unsuitable in applications where multiple passes through the portal (e.g. on a ski lift) are necessary. To enter, the smartphone must be removed from the pocket, the ticket is retrieved and presented to the optical reader device. Clearly, the described ski suit operation and multiple use entrances are overly complex. Radio technologies such as NFC (NEAR FIELD Communication) or bluetooth available in smartphones have also been proposed for ticket purchase. NFC has a range of action of a few centimeters that is too short and is therefore inconvenient. Bluetooth is a standardized technology for data transmission in the 2.4GHz ISM band and has been developed for networking devices in environments up to 10 meters. Bluetooth is used in particular for transmitting audio data. The current consumption is very high in the first bluetooth version, which is improved (bluetooth low energy) with further development starting from version 4. Recently, newer versions of bluetooth below 5.X are available that also provide positioning functionality. The functions for positioning are not mature on the one hand, but are only contained in very few smartphone models on the other hand. Bluetooth has not been possible to date as a communication channel between a mobile data carrier (ticket) and a reader device in the access channel. One reason for this is that the higher scope of action does not guarantee that the correct personnel (smartphones) data is read and processed. In US PS 10,163,178 a system for using a mobile data carrier (smartphone) is described, which system comprises reading means for the respective access channels, wherein each reading means comprises a bluetooth antenna array. A common bluetooth position transmitter with a large range of action is arranged upstream of the reading devices for the individual access channels. If the mobile data carrier approaches the entry-controlled location, it receives a signal from the location transmitter and its ticket data should be transmitted after the connection coupling (registration process). If the mobile data carrier subsequently arrives at the access gate, the bluetooth antenna array arranged there should determine the position of the data carrier. For this purpose, the bluetooth antenna array uses directional antenna lobes and measures the received field strength (RSSI). The portal is released if the validity check by the location transmitter and the location check by the antenna array in the access door are affirmative. The system described herein using bluetooth in access control in practice shows that insufficient registration capability, too long a pass-through time is required, and that personnel not immediately entering upon reaching the access door severely interfere with the process.
