Description

The invention relates to an RFID key, in particular RFID transponder unit, for communication with a locking device according to the preamble of claim 1, a locking device with an RFID lock for access or access control according to the preamble of claim 4 and an RFID programming device for programming of RFID keys, in particular RFID transponder units. Furthermore, the invention relates to a system with at least one RFID key, in particular an RFID transponder unit, for communication with a locking device, at least one locking device with an RFID lock for access or access control and at least one RFID programming device for programming RFID keys , in particular RFID transponder units. In addition, the invention comprises a locking method for controlling access or access according to the preamble of claim 13 and a method for programming RFID keys, in particular RFID transponder units.

Modern swimming pools have access controls for lockers using RFID technology. In such systems, a swimming pool visitor is asked to enter the swimming pool - i.d.R. after paying an entrance fee - an RFID key, in particular an RFID transponder unit, handed over. The RFID key or the RFID transponder unit allows the swimming pool visitor to lock a locker in the swimming pool and unlock this locker. Thus, the swimming pool visitor can leave the items not needed during his swim in the locked locker.

After the handover of the RFID key, in particular the RFID transponder unit, to the pool visitor, the RFID key or the RFID transponder unit is not coupled to a specific locker. This means that the swimming pool visitor is able to lock any free locker. For this the pool visitor brings the RFID key, in particular the RFID transponder unit, into the area of an antenna of a locking device with an RFID lock, which is attached to a locker door of a selected locker. The RFID lock and the RFID key or the RFID transponder unit exchange their identity or identify each other. In the event that the selected locker is free and with the RFID key, in particular the RFID transponder unit, so far no other locker has been closed, the RFID key, in particular the RFID transponder unit, and the RFID lock, so link that the pool visitor can lock the selected locker.

The coupling, which is noted on the RFID key, in particular the RFID transponder unit, and the RFID lock, on the one hand ensures that the locker is marked as occupied and thus no new coupling with another RFID key or one another RFID transponder unit performs. On the other hand, the coupling which is noted on the RFID key, in particular the RFID transponder unit, ensures that the RFID key or the RFID transponder unit can not close any other locker since it has already closed a locker.

After swimming, the pool visitor holds the RFID key or the RFID transponder unit in front of the locker locked by him or her. The RFID lock and the RFID key or the RFID transponder unit in turn exchange each other their identity or identify each other and also determine their coupling, which unlocks the lock or can be opened while the coupling is released. By releasing the coupling, which in turn is noted on the RFID key, in particular the RFID transponder unit, and the RFID lock, on the one hand ensures that the locker is marked as free and for a new coupling with an RFID key or an RFID transponder unit is ready. On the other hand, it is achieved that the RFID key or the RFID transponder unit can close another free, that is not coupled, or the same locker.

After leaving the swimming pool, the RFID key or the RFID transponder unit is dispensed at the entrance.

Such systems require a small amount of personnel and can easily be integrated later into an existing swimming pool operation. In the case of other fields of application in which the coupling of an RFID lock and an RFID key or an RFID tag unit is to be retained even after unlocking, problems arise with this system.

For example, in the hotel industry, in which the coupling of an RFID key or an RFID tag unit to a defined RFID lock a room door to remain throughout the stay of the hotel guest, known from the pool RFID system can not be used. From the hotel industry therefore further RFID systems for the locking of room doors of the hotel rooms of a hotel are known.

In such systems, a hotel guest is handed an RFID key, in particular the RFID transponder unit, in the form of a card or a wristband during the booking process at the hotel reception. The RFID key, in particular the RFID transponder unit, allows the guest access to a hotel room having a locking device with an RFID lock.

The access control systems for hotel rooms are systems in which the locking systems are connected via a network to a computer at the reception. In these systems, when registering the hotel guest, any RFID key or RFID transponder unit is read in the computer at the reception and the locking system is coupled via the network with this RFID key or RFID transponder unit. Unlocking of the room door is then only possible by the locking system in conjunction with the coupled RFID key, in particular the RFID transponder unit.

When the guest logs out at the reception, the RFID key is handed back and the reception staff solves the coupling between the RFID key or RFID transponder unit and the RFID lock via the network. Even if the hotel guest does not log off at the reception desk and therefore does not hand in the RFID key or the RFID tag unit, or in the event that the hotel guest loses the RFID key, the reception staff will be able to to decouple the locking system and the lost or lost RFID key or RFID transponder units via the network connection, so that the lost or lost RFID key or RFID transponder units no longer allow access to the hotel room.

However, this system has the disadvantage in comparison to the system used in the swimming pool that a network connection of the RFID locks with a central office for establishing and releasing the coupling is necessary and that for the production and release of the coupling additional personnel expenses must be operated.

The present invention is based on the problem of finding RFID locks and RFID keys, in particular RFID transponder units, for applications in which the coupling of an RFID key, in particular an RFID tag unit, to an RFID lock also follows can remain unlocking a locking device with an RFID lock. Furthermore, this should not require a network connection to the RFID locks, so that the installation effort - even with subsequent installation in an existing system - can be kept low. In addition, a manufacture and release of the coupling should be possible without additional personnel costs.

This problem is solved according to the invention by an RFID key, in particular an RFID transponder unit, for communication with a locking device according to claim 1, a locking device with an RFID lock for access or access control according to claim 4 and an RFID programming device for programming RFID tags. Keys, in particular RFID transponder units, according to claim 11. Furthermore, the problem is solved by a system having at least one RFID key, in particular an RFID transponder unit, for communication with a locking device, at least one locking device with an RFID lock for access or access control and at least one RFID programming device for programming RFID tags. Keys, in particular RFID transponder units, according to claim 12. In addition, the problem is solved by a locking method for controlling an access or access according to claim 13 and a method for programming RFID keys, in particular RFID transponder units, according to claim 15.

The RFID key according to the invention, in particular the RFID transponder unit, is used for communication with at least one locking device, that is to say with one or more locking devices, with one or in each case with an RFID lock. Furthermore, the RFID key according to the invention, in particular the RFID transponder unit, also serves for communication with at least one RFID programming device, ie with one or more RFID programming devices.

The RFID key, in particular the RFID transponder unit, has an identification means with which at least one of predefined RFID locks can be identified. In particular, predefined RFID locks herein include only RFID locks that are standardized to one or more specified standards, such as ISO 15963, and that have certain unique identifiers (UIDs). The identification means of the RFID key, in particular of the RFID transponder unit, is thus restricted to a certain number of RFID locks, which can be identified by the RFID key, in particular the RFID tag unit.

Furthermore, the identification means also serve to identify one or more RFID programming devices of predefined RFID programming devices. The predefined RFID programming devices here include in particular only RFID programming devices, which are standardized according to one or more specified standards and have certain unique identifiers or serial numbers (UIDs).

In addition, the inventive RFID key, in particular the RFID transponder unit, has a coupling means, wherein the coupling means serves to couple an identified RFID lock with the RFID key, in particular the RFID transponder unit, or a coupling between the RFID Key, in particular the RFID transponder unit, and the identified RFID lock. Coupling here means establishing a connection, in particular of the RFID key or the RFID transponder unit with the identified RFID lock by noting the unique identifier (UID) or another non-mistakable identifier of the RFID lock in the RFID key, in particular the RFID transponder unit, or in a memory of the RFID key or the RFID transponder.

The RFID key according to the invention, in particular the RFID transponder unit, additionally comprises a receiving means for receiving a radio signal with a time or period indication from an RFID programming device identified with the identification means and a storage means for storing the received time or period information. If the RFID key or the RFID transponder unit is thus brought into the area of an RFID programming device, the RFID programming device is one of the predetermined programming devices, and the RFID programming device is therefore identified by the RFID key, in particular the RFID transponder unit , a time indication sent by the RFID programming device with a radio signal or a period information transmitted by the RFID programming device with a radio signal is received by the receiving means of the RFID key and on the RFID key, in particular the RFID transponder unit, or in the memory of the RFID key, in particular the RFID transponder unit stored.

Furthermore, the RFID key has a transmission means for transmitting a radio signal with the stored period or time indication. This radio signal is sent by the RFID key, in particular the RFID transponder unit, during or after the coupling with an RFID lock to the coupled RFID lock.

Furthermore, the invention comprises a locking device with an RFID lock for access or access control. The locking device is used in particular for controlling the access to the contents of a container, e.g. a cupboard. The locking device has an identification means for identifying at least one of predefined RFID keys or RFID transponder units.

Predefined RFID keys, in particular RFID transponder units, here include, analogous to the above for predefined RFID locks executed, in particular RFID key or RFID transponder units, which are standardized according to one or more specified standards, such as ISO 15963, and certain have unique identifiers (UIDs). Accordingly, therefore, the number of RFID keys, in particular the RFID transponder units, which are identifiable by the identification means of the locking device, limited by the latter requirements.

Furthermore, the locking device according to the invention also has a coupling means. The coupling means is used for coupling and decoupling of the RFID lock on or with an RFID key, in particular RFID transponder unit. The coupling means is designed to allow at any time only a coupling of the RFID lock with an RFID key, in particular an RFID transponder unit. That is, the RFID lock can not simultaneously record or memorize a coupling to two RFID tags or RFID tag units.

In addition, the RFID lock on a receiving means with which a radio signal with a period or time indication of an identified RFID key or an RFID transponder unit is receivable. Here, the receiving means is designed to receive the radio signal with a period or time indication only during or once after the coupling with the RFID key, in particular the RFID transponder unit. The reception of the radio signal with a period or time indication is therefore dependent on the coupling and is directly in the communication sequence of the RFID key, in particular the RFID transponder unit, and the RFID lock, where the coupling takes place of the RFID key, in particular the RFID transponder unit, sent or received by the RFID lock.

In addition, the RFID lock on a time control, on the one hand, the coupling is noted for a period that depends on the time or period of the received period or time indication, and on the other hand, the lock with the locking device is released only in case that Coupling is still noted. A note of the coupling is here e.g. by storing in the RFID lock that a coupling has taken place, whereby the storage of an identifier, e.g. the unique identifier (UID) of the coupled RFID key or the RFID transponder unit, takes place in the RFID lock.

Further, this annotation of the coupling is dependent on the period of the received period indication or the time of the received time indication. This means that the duration for which the RFID lock is coupled to or to an RFID key, in particular to an RFID transponder unit, is determined in particular by the period of the received time period specification or the time of the received time specification. After expiration of the period of the received period information or after reaching the time of the received time indication, the RFID lock releases the coupling to the RFID key or to the RFID transponder unit, wherein according to a particular embodiment of the invention, the coupling is still maintained, ie noted, until the locking device moves on Expiration of the period or after reaching the time in the case of a locked state is unlocked.

In addition, the time control to release the locking with the locking device only in the case, so to allow, if the coupling is still noted, so it continues to exist or is stored. After expiration of the period of the received period indication or after reaching the time of the received time indication so locking or locking with the locking device is no longer possible. It is e.g. conceivable that the timing of the locking device comprises a test means which checks whether a coupling is noted or not, and a release means which prohibits or permits the locking on the basis of the test result of the test means.

Furthermore, the invention has an RFID programming device, in particular an RFID programming terminal, for programming RFID keys, in particular RFID transponder units. For this purpose, the RFID programming device according to the invention comprises input means with which either amounts of money can be paid in or amounts of money can be deposited and a time or period specification can be set or entered. In particular, the input means have banknote readers and coin validators as well as input keys.

In addition, the RFID programming device according to the invention or the RFID programming terminal, a time recording means, in particular an RFID reader / writer, with which a period or a time indication is determined by means of a deposited amount of money or by means of a set time or period information.

Accordingly, according to the first alternative, an amount of money is first input with the input means. This amount of money is, especially after confirming the entry with an "OK" button, converted in the time recording means in an indication of a future date or in an indication of a period, ie the time or period by means of the deposited funds or depending on the amount of money paid. For example, a sum of one euro and 50 cents is equivalent to one day. If six euros are paid in with the input means, the time recording means determines an indication with a time from the time of the deposit of four days in the future or an indication with a period of four days.

According to the second alternative, a future time or period information is entered with the input means and then a sum of money is paid. If it is determined by the input means in this case that the paid-in monetary amount is sufficient for the selected time of the time specification or period of the period indication, then the time acquisition means, e.g. After confirming the entry with an "OK" button, based on the selected or set time or period information, a time or period information that corresponds to the set time or period information.

The time or period information determined with or in the time recording means is then transferred to a transmission means which generates a radio signal. The radio signal contains the determined time or period information and transmits it to an RFID key, in particular an RFID transponder unit.

According to a particular embodiment of the RFID programming device according to the invention, in particular the RFID programming terminal, a plurality of RFID keys, in particular RFID transponder units, are stored within the device. After input with the input means, one of the RFID keys, in particular one of the RFID transponder units, is brought into the area of an antenna of the transmitting means of the RFID programming device or the RFID programming terminal with a first transport means of the apparatus and the determined time specification or the determined Period information to this RFID key or transmit this RFID transponder unit. After the transfer of this RFID key or this RFID transponder unit is transported with a second transport of the device in an output slot. These two transport processes can also be combined depending on the design and construction of the RFID key or RFID transponder unit. For example, in a design of the RFID key or the RFID transponder unit as a plastic or paper wristband, a single transport process to the RFID antenna can take place and there automatically cut off immediately after the data transmission and falls into the Output chute are dropped, while in an embodiment of the RFID key or the RFID transponder unit as a silicone bracelet both transport operations take place. There, the RFID key or the RFID transponder unit can be removed from the RFID programming device or the RFID programming terminal.

In addition, the invention comprises a system with at least one RFID key, in particular an RFID transponder unit, for communication with at least one locking device, at least one locking device with an RFID lock and at least one RFID programming device, in particular RFID programming terminal.

Further, the invention also includes a locking method for controlling access or access. The locking method initially has an identification step. In the identification step, an RFID key, in particular an RFID transponder unit, and an RFID lock identify each other. After the RFID key, in particular the RFID transponder unit, and the RFID lock have identified, a coupling step is performed. In the coupling step, the identified RFID key and the RFID lock connect to each other, wherein this coupling takes place only if neither the identified RFID key or the identified RFID tag unit to another RFID lock, so the identified RFID lock excluded, still the identified RFID lock is coupled to a further RFID key, in particular a further RFID transponder unit, that is to say the identified RFID key.

In addition, the locking method according to the invention comprises a receiving step. In the receiving step, a radio signal is received by the RFID lock, which was identified by the RFID key, in particular the RFID transponder unit, with a time or period information, this of the identified RFID key, in particular the RFID Transponder unit, is sent. The transmission, that is the sending and the receiving, the period or the time indication takes place during or once after the coupling of the identified RFID key, in particular the RFID transponder unit, and the identified RFID lock.

In addition, the locking method according to the invention has a timing step. In the timing step, the coupling is noted for a duration dependent on the time period or time of the received time or period indication. Furthermore, in the timing step, a lock, which is triggered in particular by a triggering step, is released with the locking device only in the event that the coupling is still noted.

Furthermore, the invention comprises a method for programming RFID keys. The method comprises an input step in which a monetary amount is paid in or a period or time is entered and a monetary amount is paid. In addition, the method comprises a time recording step, in which a period or a time indication is determined by means of the deposited amount of money or by means of the deposited amount of money and the set period or the set time indication. In a transmitting step of the method, a radio signal with the determined period or time information is sent to an RFID key.

Thanks to the invention, the coupling of an RFID key is made to a defined RFID lock without network connection of the RFID lock and without the expense of additional personnel.

The invention thus allows a person to use the locking device, for example, attached to a container, for an uninterrupted period of time, wherein the person can select any "free" locking device for this purpose. The use here includes any number of locking and unlocking. Exclusive use means uninterrupted use without the interim use of another person. When the lock is locked, the container is available exclusively to the user. If the user unlocks the lock again, it can then either be locked again by him or by another user who connect with another valid RFID key or another valid RFID transponder unit a coupling with this locking device and thus with the container can. In this case, the previous user is no longer entitled to use the container, even if he has booked a paid remaining life on his key.

First, therefore, a user "buys" himself with the RFID programming device, e.g. a period corresponding to a useful life stored on an RFID key, in particular an RFID tag unit. Then the person selects any locking device according to the invention with an RFID lock, e.g. is arranged on a container, and couples the RFID key, in particular the RFID transponder unit, to the RFID lock of the locking device. A coupling takes place simply in that the RFID key, in particular the RFID transponder unit, and the RFID lock are mutually brought into their receiving or transmitting areas. When or immediately after pairing, the information with the "purchased" period or the useful life is transferred to the lock and stored in the RFID lock. Due to the time control in the RFID lock, the pairing is maintained at least until the "purchased" period has expired.

According to one embodiment of the RFID key according to the invention, in particular the RFID transponder unit, this / these comprises a housing with an RFID transponder. The housing is formed with and / or made of silicone, plastic and / or laminated paper and encloses the RFID transponder air and waterproof. It is also waterproof. Furthermore, the housing formed with silicone is designed as a multiple on and deductible bracelet. Multiple on and off means that the bracelet can be applied to the arm of a person, the application in particular also a closing of the bracelet, e.g. with a closure that includes. The removal of the bracelet analogously includes in particular the opening of a closure. The phrase "multiple" put on and off means that the wristband does not have to be destroyed when it is dropped. The RFID key (transponder) is thus easily re-applied after dropping. This is especially true in a training silicone, but not in a training of laminated paper. The bracelet is preferably designed tearproof.

Preferably, the invention can be used in a hospital. In this hospital, the invention can be used to allow patients to close their valuables in the drawer of a bedside table or in a cabinet or other container in the hospital room or in another room and the RFID key, in particular the RFID Transponder unit, always carry with you. Particularly advantageous is then the formation of the housing of the RFID key or the RFID transponder unit as multiple on and offable with silicone, plastic and / or laminated paper formed bracelet. This bracelet can be worn during hospitalization, even while sleeping, without restricting the patient. In applications and / or treatments of the patient, however, in which the bracelet may not be worn, for example, not to destroy the RFID transponder, such as the X-ray, a simple temporary removal of the bracelet is possible.

According to a further embodiment of the RFID key or the RFID tag unit according to the invention, this or these has no sharp-edged surfaces and / or outer metals in order to minimize the risk of injury when carrying the RFID key or RFID transponder unit.

The housing formed as a bracelet of the RFID key, in particular the RFID transponder unit, according to a further embodiment of the RFID key or the RFID transponder unit according to the invention longer than standard bracelets, namely e.g. 200 millimeters long, to facilitate the creation of the bracelet even in the movement restricted, especially elderly, persons.

According to a further embodiment of the RFID key (transponder) according to the invention, the latter has an RFID transponder with an antenna which is designed according to an ISO standard, e.g. ISO 15693, are standardized. Standardized components, which are produced in large numbers, are cheap and thus well-suited for the inexpensive production of the RFID key (transponder).

According to a further embodiment of the RFID key according to the invention, in particular the RFID transponder unit, the housing of the RFID key designed as a wristband has a symbol on its upper side in the area of the RFID transmitting and receiving antenna of the RFID transponder. The symbol also helps technical laymen to position the RFID key or the RFID tag unit correctly in the area of an RFID lock in order to open and close or lock and unlock this RFID lock.

Furthermore, the housing of the RFID key, in particular the RFID transponder unit designed as a bracelet, has a closure according to a further embodiment of the RFID key or RFID transponder unit according to the invention. The closure, in particular in an embodiment of the bracelet as a silicone bracelet, comprises holes in a first part of the bracelet and elevations on a second part of the bracelet, wherein the shape of the elevations is in particular spherical or conical. The holes are in particular elongated holes, which is narrower in the region of the elongated hole, which is directed to one end of the bracelet, as in the opposite region of the elongated hole. The surveys are in particular on the top of the bracelet, so the side of the bracelet, which is not on the skin after donning. Such a closure has the advantage that it - just to be able to wear the bracelet while sleeping - exerts the least possible punctual pressure on the arm and is therefore comfortable to wear. Furthermore, such a closure is easy to apply and above all fast - e.g. in an emergency - removable. For laminated paper, the closure is preferably formed by means of one or more adhesive surfaces.

In addition to the embodiments of the RFID key, embodiments of the locking device are also included. According to a first embodiment, the timing of the locking device on means for determining a start and / or a final count on the basis of the period of the received period indication or based on the time of the received time indication. The period of the received period indication or the time of the received time specification corresponds to the period or time of received during or after the coupling period or time indication of an RFID key according to the invention, in particular an RFID transponder unit according to the invention or an embodiment of the RFID according to the invention Key or the RFID transponder unit according to the invention has been sent.

According to this embodiment, the locking device also has counting means for counting. The counting means counts from a predefined or a determined starting value up to a predefined or a determined final value with a predefined, largely constant counting frequency.

According to a further embodiment of the locking device, in the means for determining a start and / or end count, e.g. already set a start count, such as a zero, or predefined. The Endzählwert is then determined based on a period of the received period information so that the time period or the duration that the counting means for counting from the start count to the final count value corresponds to the period of the received period indication. According to a further embodiment, it is also conceivable that an end count is already set. Then, the start count value is determined such that the time period or the duration that the counting means requires for counting from the start count to the end count corresponds to the period of the received period indication. According to another embodiment, the counting means is a clock with a date function, e.g. as a radio clock, trained. In this case, the start count value is determined as the current time with the current date, and the end count value is determined or defined as the time of the received time specification, which in this case corresponds to a time and a date.

Thanks to the means for determining a start and / or end count and the counting means the duration can be fixed in a simple manner with the locking device, in which the locking device can be used by a person.

According to a further embodiment of the locking device, the coupling means are on the one hand designed so as to separate in the case of an unlocked RFID lock on reaching the final count with the counting means the coupling to the coupled RFID key, in particular the RFID transponder unit. On the other hand, in the case of a locked RFID lock on reaching the final count with the counting means, the coupling means are designed to disconnect the coupling to the coupled RFID key, in particular to the RFID transponder unit, as soon as the RFID lock is unlocked. That is, after reaching the Endzählwertes the coupling between the RFID key and the locking device is released when the locking device or the RFID lock is unlocked, and that the coupling, when the locking device is locked, remains until the next release remains and only then will it be solved. The release of the coupling with the timing in the locking device corresponds to a deletion of the note of the coupling.

Unlocking the locked coupled locking device is thus possible at any time with the coupled RFID key or the coupled RFID transponder unit. Thus, a user of the locking device whose "purchased" duration for the use of the locking device during its absence expires, is not denied to unlock the locking device one last time.

• das Betätigen eines Auslösers der Verriegelungsvorrichtung und/oder
• den Ablauf einer vordefinierten Zeitdauer nach der Annäherung eines mit dem RFID-Schloss gekoppelten RFID-Schlüssels, insbesondere einer RFID-Transpondereinheit, und/oder
• den Ablauf einer vordefinierten Zeitdauer nach dem Entfernen eines mit dem RFID-Schloss gekoppelten RFID-Schlüssels, insbesondere einer RFID-Transpondereinheit.

According to a further embodiment of the locking device, this has a Verriegelungsauslösemittel. With the lock release means a lock request can be triggered, wherein the lock request is triggered by

• the actuation of a trigger of the locking device and / or
• the expiration of a predefined period of time after the approach of an RFID key coupled to the RFID lock, in particular an RFID transponder unit, and / or
• the expiration of a predefined period of time after the removal of an RFID key coupled to the RFID lock, in particular an RFID transponder unit.

The predefined amount of time after which a lock request is triggered begins to run if e.g. an RFID key coupled to the RFID lock, in particular an RFID transponder unit, for unlocking the locking device from the RFID lock, in particular after the approach, is identified. Furthermore, however, any action on the locking device is conceivable through which the predefined period begins to run. The duration of time is predefinable depending on the application of the locking device, wherein, according to one embodiment, a time duration of zero, ie of zero seconds, is also conceivable. In the latter case, an immediate locking request is then triggered when an RFID key coupled to the RFID lock, in particular an RFID transponder unit, is approximated after previous absence and / or removed after prior presence.

Analogous to the locking device, the locking method according to one embodiment has a step in which a start and / or end count are determined based on the period of the received period information or based on the time of the received time indication. In a counter start step, a counting means is then used for counting a predefined one or the one determined Starting value up to a predefined or the determined end value with a predefined largely constant counting frequency started. A lock request is then initiated in a lock request step.

Thanks to a triggered locking request, the locking device is informed of a desired lock, the lock request only leading to locking with the locking device if the time control or release means of the time control releases the lock. According to a particular embodiment, therefore, the locking request is forwarded to the timing of the locking device.

According to a further embodiment, the RFID lock of the locking device has an output means for outputting a signal. This signal is e.g. an acoustic and / or optical signal and is output by the output means upon reaching the final count with the counting means.

With the output means a user of the locking device is thus shown that the "purchased" period has expired and only a single opening or unlocking the locking device is possible because then the coupling is deleted in the locking device.

According to a further embodiment of the locking device, this has at least one energy source, in particular an accumulator or a battery. The energy source is used to supply the locking device with energy. Thus, the locking device is self-sufficient, in particular without connection to an external voltage source, can be used. Advantageously, two battery compartments are provided. A firmware of the locking device can permanently or repeatedly measure the battery state of the first battery compartment and can switch off the first battery compartment upon reaching a predetermined critical battery state value and then resort to the second battery compartment.

According to a further embodiment, the locking device comprises a cassette which can be installed in a cabinet with a drawer which can be inserted into the cassette or a drawer which can be inserted into a cabinet (without a cassette). The variant with cassette is advantageous for retrofitting an existing cabinet, especially bedside table or bedside table provided. In this way, a locking device be integrated with corresponding drawer without substantial structural changes of the existing cabinet later in the cabinet. Thanks to this embodiment of the locking device, this serves to control the access to the contents of the cabinet.

The RFID lock advantageously comprises an electronic part and a mechanical part, which has a bolt, by means of which an opening of the drawer can be locked. The bolt is offered in two variants:

According to variant 1, this latch is preferably manually displaceable by the user of the lock. However, the displaceability of the bolt is controlled by the electronic part. The RFID lock comprises a pin, by means of which the bolt can either be set or released. The operation of the pen requires little electronic power, while the necessary actuation energy for the latch is provided manually by the user. In this way, electronic energy can be saved and thus the life of the energy source can be substantially extended. Thus, maintenance cycles are noticeably longer. The electrical part of the RFID lock is advantageously integrated into a functional unit from the drawer, the mechanical part of the RFID lock and optionally the cassette.

According to variant 2, an electronic latch is provided so that the user no longer has to perform anything manually. The locking is preferably carried out by a special energy-saving solenoid. Preferably, it is an electric lifting magnet with magnetic locking of the armature in the stroke end position even in the de-energized state. In the case of energization of the solenoid, the armature is moved from a Hubanfangsstellung in the Hubendstellung. In this position, the armature is magnetically locked. By reversing the polarity of the supply voltage of the solenoid, the armature is unlocked again. The armature is then brought by an external force or by a return spring back to the Hubanfangsstellung.

In a further preferred embodiment, the position of the bolt and / or the pin is controlled by one or more lifting devices, which may for example each have a servo motor, a star wheel and / or one or more articulated arms.

Fig. 1 shows an embodiment of the RFID key according to the invention in the form of an RFID transponder unit 10, wherein only one formed as a bracelet housing 12 of the RFID key 10 is shown. The bracelet 12 is formed entirely or partially of silicone and has a first part 14 and a second part 16, which are interconnected by a central part 18. In Fig. 1 is a plan view, so a view of the top of the bracelet 12, shown. The top corresponds to the side that is not applied to an applied bracelet 12 on the body.

In the middle part 18 of the bracelet 12, a symbol 20 is mounted on the top of the bracelet 12. Further, in this middle part 18, an RFID transponder, which comprises a microcontroller and an antenna, which are arranged on a circuit board, accommodated, which in the following in connection with the 3 and 4 is explained.

The second part 16 of the bracelet 12 has holes 22, which holes are formed like slots. The opening width of each elongated hole is larger on one side 24 of the elongated hole than on the other side 26 of the elongated hole. The holes 22 are thus each tapered. Furthermore, the first part 14 of the bracelet 12 has elevations 28. Fig. 2 shows an enlarged view of a first part 14 of the bracelet 12 from the side. Here, the special shape of the elevations 28 is shown, which are formed according to the illustrated embodiment drop-shaped with a narrower region 30 and a wider region 32. The elevations 28 are mounted on the top of the bracelet 12.

The holes 22 and the projections 28 together form the closure for closing the bracelet 12. For this purpose, the holes 22 - after the bracelet 12 was placed around the arm of a person - with the side 24 of the elongated hole, which has a larger opening width, on the Raises 28 slipped. By pulling on the bracelet, the narrow portion 30 of the elevations moves to the side 26 of the elongated hole, which has a narrower opening width. The projections 28 are thus "pinched" in the holes 22 on the side 26, which has a narrower opening width.

Such bracelets are advantageously formed of silicone. In other embodiments, instead of silicone, plastic or laminated paper is used. In these cases, the closure can also be realized otherwise, in particular by adhesive surfaces and / or adhesive closures.

Fig. 3 shows a schematic representation of the functional part of an RFID transponder unit, namely an RFID transponder 34 with a microcontroller 36 and an antenna 38, which are arranged on a circuit board 39. In the middle of the schematic representation according to Fig. 3 the microcontroller 36 is provided which is connected to and surrounded by an antenna 38. The microcontroller 36 controls communication with locking devices having an RFID lock and with an RFID programming device or an RFID programming terminal. The antenna 38 represents the communication interface for communication with the interlocking devices and with the RFID programming devices. The microcontroller 36 and the antenna 38 are arranged in a housing, in particular the wristband 12, the material of the housing being the microcontroller 36 and the antenna 38 completely encloses.

Fig. 4 shows a detailed schematic representation of the microcontroller 36 of the RFID transponder 34 according to an embodiment of the RFID key according to the invention or the RFID transponder unit 10. The microcontroller 36 has inter alia a receiving means 42 and a transmitting means 44. The receiving means 42 and the transmitting means 44 are arranged in a transmitting and receiving unit 46. According to a further embodiment, the receiving means 42 and the transmitting means 44 are combined in a transmitting and receiving means.

The antenna 38 with the receiving means 42 serves to receive an electromagnetic alternating field which is transmitted by an RFID lock or by an RFID programming device. The energy received by the antenna 38 serves as a power supply to the microcontroller 36 during the communication process. Another microcontroller in the latching device, e.g. on the container or the drawer is energized by batteries. If then a passive RFID transponder unit or a transponder (in the bracelet) in the electromagnetic field of the transponder comes from the board, then this energy is sufficient to read the passive chip in the bracelet or the RFID transponder unit and describe. From the electromagnetic alternating field 42 commands, which include in particular binary data, decoded by the receiving means 42 and then further processed in the microcontroller 36. The RFID key or RFID transponder unit 10 responds to the commands received by modulation of the alternating electromagnetic field transmitted by the RFID lock or RFID programming device. For this purpose, the electromagnetic field is weakened or amplified by the transmitting means 46. In the following, the data transmitted by the electromagnetic alternating field is simply called radio signals.

Furthermore, the microcontroller 36 has an identification means 48. The identification means 48 is used to identify RFID locks or RFID programming devices that transmit a radio signal that is received by the antenna 38 and the receiving means 42. For this purpose, the identification means 48 compares a unique identifier (UID) sent by an RFID lock or by an RFID programming device with identifiers previously stored in a memory of the RFID key or RFID transponder unit 10 or of the microcontroller 36 and thereby predefined or predetermined. If it matches, the identification means 48 notifies the RFID programming device or RFID lock that sent the unique identifier as an identified RFID programming device or as an identified RFID lock.

In the case of an identified RFID programming device, the RFID key or the RFID transponder unit 10 receives a time or a time indication, which is stored in a memory 50. In the case of an identified RFID lock takes place with coupling means 52, a coupling with the RFID lock instead, if in the memory 50, a time or a time indication is stored and the RFID key 10 has not yet been coupled with another RFID lock was or is. When coupling the unique identifier of the RFID lock is stored in the memory 50 to recognize the RFID lock and transmit the stored period or the stored time information to the RFID lock with a radio signal. In the memory 50, the coupling is noted, that is stored, so that the RFID key 10 can not enter into any further coupling with another RFID lock.

In particular, the identification means 48 and the coupling means 52 are realized according to an embodiment with the microcontroller 36 and a software in the microcontroller 36 and only for clarity here as separate blocks in Fig. 4 shown. Furthermore, the transmitting and receiving unit 44 is shown as part of the microcontroller 36, wherein according to another embodiment, a transmitting and receiving unit 44 can be realized, which is independent of the microcontroller 36 but electrically connected to the microcontroller 36 and the antenna electronic component of the unit 34th in Fig. 3 equivalent. Advantageously, a Hall sensor is provided to the microcontroller 36, by means of which the position of the Hall sensor and thus of the RFID transponder unit in front of the container or the drawer can be detected. Thus, it can be ensured that only when the RFID transponder unit is immediately in front of the container, the electronic locking operation is performed.

Fig. 5 shows an embodiment of an RFID programming device or an RFID programming terminal 54 for programming RFID keys or RFID transponder units 10. The RFID programming device 54 has input means 56, namely cash deposit means 58 for depositing funds and time input means 60 for inputting a period indication , on. For this purpose, the input means 56 or the cash deposit means 58 has, in particular, dummy readers 62 and coin validators 64, wherein Fig. 5 only the insertion openings of the bill reader 62 and the Münzprüfer 64 are shown. Furthermore, the RFID programmer 54 has a money return 66 for returning change. The money return is also often called Hopper. In addition, the RFID programmer 54 has a display 68 with which deposited funds and / or set periods are displayed.

Furthermore, the RFID programming device 54 has an output shaft 70 and a return shaft 72. The output shaft 70 and the return shaft 72 are illuminated with lights 74, 76. Programmed RFID keys or RFID transponder units are output with the output shaft 70, and the return slot 72 returns RFID keys or RFID transponder units 10 that are no longer needed. This applies in particular to an embodiment of the RFID transponder units in the form of silicone wristbands, which can be reused.

For a better representation of the function of the RFID programming terminal 54 shows Fig. 6 a schematic representation of the internal structure of an embodiment of the RFID programming terminal 54. The RFID programming terminal 54 has in its interior a storage container 78 for storing RFID keys or RFID transponder units 10. Furthermore, in Fig. 6 also the input means 56 shown. If a monetary amount is entered with the cash deposit means 58, this appears on the display 68 together with a period of time. For this purpose, in a time recording means 80, a period of time is determined by means of the deposited amount of money or depending on the paid-in amount of money and displayed with the display 68. If this period information is confirmed, in particular by pressing a button, then an RFID key or an RFID transponder unit 10 is conveyed out of the storage container 78 into a programming area 82. The time detection means 80 transmits the determined period information to a transmission means 84, which sends the determined period information to the RFID key or RFID transponder unit 10, which has been brought into the programming area 82. The RFID key or RFID transponder unit 10 stores the period information and has thus been programmed by the RFID programming terminal 54. The programmed RFID key or RFID transponder unit 10 is then transported into the output shaft 70, from which the RFID key can be removed.

Fig. 7 shows an embodiment of a locking device 86. Of the locking device 86 is in Fig. 7 only one drawer 88 shown, which is inserted into a cabinet 90. The drawer 88, like the RFID key 10, has a symbol 92. The cabinet 90 without the locking device 86 is a commercially available cabinet 90, which in addition to the locking device 86 has more drawers, subjects or doors. The locking device additionally has a trigger 94 designed as a pushbutton, for example, or a triggering means 94 operable to transmit a lock request to an RFID lock of the locking device 86. Furthermore, the locking device 86 has an output means 95 for outputting a signal. In this embodiment, the output means 95 is an LED. According to a further embodiment, the locking device 86 additionally or alternatively to a speaker, in particular a piezo loudspeaker on.

Fig. 8 shows the locking device 86 from Fig. 7 without the cabinet 90. The locking device includes a drawer 88, an RFID lock 96 and a power source 98. The power source 98 includes a battery compartment in which commercially available batteries such as mignon cells are housed. According to other embodiments also accumulators or other energy sources 98 are possible. The power source 98 supplies power to the RFID lock 96. The locking device 86 is shown from the rear side so that the symbol 92 is not visible behind the RFID lock 96.

The RFID lock 96 has a latch 100 on one side. This latch 100 can be manually operated by the user, for example, when a pen is in a release position. If, on the other hand, this pin is in a blocking position, the bolt 100 can not be displaced. The pin can therefore influence the displaceability of the bolt 100, i. either release the lock 100 or lock it. The operation of the pin requires little electrical power, while the operation of the bolt 100 requires a much higher energy consumption, but does not have to be provided by the power source 98, but is provided by the user.

In an alternative embodiment, however, the RFID lock 96 has a latch that can be extended and retracted by the RFID lock 96. For this purpose, the RFID lock 96 on a servomotor or solenoid, not shown, wherein according to other embodiments, other drives are possible to move the latch 100. An extension of the bolt 100 corresponds to a locking and retraction of the bolt 100 corresponds to unlocking.

The RFID lock 96 and the power source 98 have screw holes 102 which serve to connect the RFID lock 96 and the power source 98 to the drawer 86. According to other embodiments, the locking device 86 has no drawer, in which case the locking device 86, comprising the RFID lock 96 and the power source 98, can be subsequently integrated in an existing drawer of a cabinet by means of the screw holes 102.

Fig. 9 shows a cassette 104, which is a part of the locking device 86 according to an embodiment of the locking device 86 according to the invention. The cassette 104 serves to integrate a locking device 86 with a drawer 88, retrospectively in an existing cabinet 90 without having to make structural changes to the cabinet 90. For this purpose, the cassette 104 is inserted into an existing compartment of a cabinet 90, from which a previously placed drawer has been removed, and fastened by means of screw holes 106 on the cabinet.

The cassette 104 is from the same view as the drawer 88 in FIG Fig. 8 shown and has an opening 108 in the form of an elongated hole. If one imagines the cassette 104 with the drawer 88 inserted therein, the opening 108 is adjacent to the latch 100 of the RFID lock. The lock will not take place up, but to the side. When locking with the RFID lock 96, the latch 100 is moved into the opening 108 and the drawer is thus largely immovably enclosed in the cassette 104. In Fig. 9 extends the latch 100 vertically upwards, so that the opening 108 is located just above the bolt 100. In alternative embodiments, the lock 96 and latch 100 are arranged such that the latch extends to the side or down. In a corresponding manner, the opening 108 is then arranged laterally or on the underside of the drawer 88.

Fig. 10 shows a schematic representation of the RFID lock 96. The RFID lock 96 has, shown here open, housing 110 with screw holes 102 on. Within the housing, a microcontroller 112 is arranged, which is connected to an antenna, not shown for clarity, which is also arranged in the housing 110. Furthermore, the microcontroller 112 is electrically connected to a servomotor 113 or a lifting magnet, which can only move a latch 100, shown only schematically.

The microcontroller 112 of the RFID lock 96 has a receiving means 114 and a transmitting means 116. The receiving means 114 and the transmitting means 116 are arranged in a transmitting and receiving unit 118. According to a further embodiment, the receiving means 114 and the transmitting means 116 are combined in a transmitting and receiving means.

With the transmitting means 116, an alternating electromagnetic field containing data to be transmitted is generated. An RFID key, in particular an RFID transponder unit 10, responds to the received data by the electromagnetic alternating field emitted by the transmitting means 116 being modulated by the RFID key or the RFID transponder unit 10. The modulation of the alternating electromagnetic field is decoded by the receiving means 116 and thus obtained the answer. The transmitted data are - as already mentioned above - simply radio signals.

Furthermore, the microcontroller has an identification means 120. The identification means 120 serves to identify RFID keys or RFID transponder units 10 which send a radio signal with its unique identifier for its identification. The identification means 120 compares the unique identifier with stored or unique identifiers. If they match, the identification means 120 notifies the RFID key or the RFID transponder unit 10, which has sent the unique identifier, as an identified RFID key or identified RFID transponder unit 10.

Furthermore, the RFID lock 96 has a coupling means 122 and a memory 124. With the coupling means 122, a coupling with the identified RFID key or the identified RFID transponder unit 10 takes place when the RFID lock 96 has not yet noted a coupling in the memory 124. During the coupling, the unique identifier of the RFID key 10 is stored in the memory 124 for the purpose of recognizing the RFID key 10 and the received time period specification or the received time specification, which is transmitted by the RFID key with a radio signal, is stored. Furthermore, the coupling is noted in the memory 124, that is stored, so that the RFID lock 96 receives no further coupling with another RFID key 10, as long as the coupling exists.

In addition, the RFID lock 96 has a timer 126. The time control 126 has a means for determining a start and / or end count value 128 on the basis of a period of the received time period information or on the basis of a time point of the received time specification, ie on the basis of the time or period information stored in the memory 124. Furthermore, the timer 126 has a counting means 130 for counting. The counting means 130 counts from a predefined or a determined starting value up to a predefined or a determined final value with a predefined, largely constant counting frequency.

In the coupling, therefore, the counting means 130 is started with the start count. The counting means 130 then counts up to an end count value, the start count value and / or the end count value being determined on the basis of the time or period information stored in the coupling.

The counting means 130 serves to maintain the coupling until the counting means 130 has reached the final count. Upon reaching the Endzählwertes, ie after the expiration of the period of the received period indication or after reaching the time of the received time point indication, a signal with the output means 95 is output. Furthermore, the RFID lock 96 releases the coupling to the RFID key or to the RFID transponder unit 10, the coupling being kept upright, ie recorded or stored, until the locking device 86 has expired after the period of the received period of time has expired. is unlocked after reaching the time of the received time point indication in the case of a locked state.

In addition, the timer 126 is used to release the lock with the locking device only in case, so allow, as long as the coupling is noted. After expiration of the period of the period received or after reaching the time of the received time, ie after the counting means 130 has reached the final count, locking or locking with the locking device 86 is no longer possible. The output means 95 signals that the counting means 130 has reached the final count.

With the trigger 94, the in Fig. 7 is shown, a lock request is triggered by the trigger 94 is actuated, as long as the coupled to the locking device 86 RFID key or the RFID transponder unit 10 is brought into the region of the locking device 86. "In the area" here describes a distance between the antennas of the locking device 86 and the RFID key or the RFID transponder unit 10 of up to a few centimeters. In the event that the counting means 130 has not yet reached the final count, the latch 100 is extended. The locking device thus executes the locking request made with the triggering means 94.

The trigger or trigger 94 may be e.g. be mounted in the front area of the drawer 88 and activate the power supply from the power source 98 to the RFID lock 96 on a pressure applied by a user on the trigger 94 pressing force. The power supply is kept active for a predefined period of time, for example 2 to 4 seconds, so that it can be detected during this time whether an authorized RFID key or RFID transponder unit 10 is being used. Depending on whether the RFID key or the RFID transponder unit 10 is authorized or not, the check results in different consequences with respect to the opening or closing of the RFID lock 96. Preferably, an open drawer 88 at any time with a valid RFID key or an RFID transponder unit 10 are closed as long as the RFID key 10 and the RFID lock 96 have stored no further coupling. The position in which the drawer 88 can be locked, is preferably defined so that the drawer 88 is inserted into the cabinet 90 until it stops. Only in this position does the microcontroller 112 then issue a lock enable.

As already in Fig. 4 are also in Fig. 8 In particular, the identification means 120 as well as the coupling means 122 and the time control 126 according to an embodiment with the microcontroller 112 and a software implemented in the microcontroller 112 and shown only for clarity as separate blocks.

Further, also in Fig. 10 the transmitting and receiving unit 118 is shown as part of the microcontroller 112, wherein according to another embodiment, a transmitting and receiving unit 118 is realized, which is independent of the microcontroller 112 but electrically connected to the microcontroller 112 and an antenna electronic component of the RFID lock 96th equivalent.

According to one exemplary embodiment, RFID keys or RFID transponder units 10, locking device 86 as well as at least one RFID programming device or an RFID programming terminal 54, ie e.g. an embodiment of the system according to the invention, used in a hospital. The locking devices 86 are used e.g. subsequently installed or integrated into existing cabinets 90, in particular in bedside cabinets in the patient rooms, and the RFID programming devices 54 are set up in the patient-accessible areas of the hospital. A patient wishing to protect his or her valuables from theft during his / her stay in the hospital goes to the RFID programming terminal 54 where he sets the period of time with the input means 56 as the period of time he will be in the hospital. The display 68 shows an amount of money determined by the time detection means, which the patient deposits with the input means 56. The RFID programming terminal 54 sends the selected period indication to an RFID key 10 issued by the RFID programming terminal 54.

With the RFID key 10, the patient selects any free cabinet whose locking device 86 is not currently coupled to an RFID key and holds the RFID key 10 with its icon 20 in the area of the icon 92 of the selected locking device 86. The Locking device 86 or the RFID lock 96 of the selected locking device 86 and the RFID key or the RFID transponder unit 10 couple. In the coupling, the period information which is stored on the RFID key or the RFID transponder unit 10 and has been transmitted from the RFID programming terminal 54 to the RFID key or the RFID transponder unit 10 is from the RFID key or the RFID transponder unit 10 is transmitted to the locking terminal 54. The lock terminal 54, when coupled, starts counting means 130 of a timer 126, the counting means counting up to an end count determined by the period of the transmitted period indication. The patient can now lock and unlock the cabinet 90 with the terminal 54. However, locking is no longer allowed when the terminal count has been reached or exceeded by the counting means 130. Unlocking is only possible once after reaching the final count value.

Fig. 11 shows a schematic representation of a lifting device 140, by means of electrical energy in a mechanical linear movement of a locking element 142nd is converted. The locking element 142 drives either the example in connection with Fig. 10 explained latch 100 or even provides for the locking of the container or the drawer 88. The locking element 142 is driven by means of a preferably designed as a star wheel 144 lifting drive, which in turn is driven by a servomotor, in particular servomotor.

The star wheel 144 has a plurality of lever arms 146, each provided with one or more holes 148, which serve to receive a connecting pin 150, by means of which such lever arm 146 is connected to the locking element 142.

The plurality of holes 148 and lever arms 146 allow flexible attachment of the locking element 142 for different mounting positions, which is particularly advantageous in different configurations of bedside cabinets, etc.

The locking element 142 is guided in a guide tube 152. This guide tube 152 has a stop member 154 for securing the guide tube 152 to a wall portion of the drawer or container by means of a nut 156 or other fastener such as a tight fitting rubber plug.

If the star wheel 144 rotates, the locking element 142 is displaced axially. So that the locking element 142 can slide in the guide tube 152 with little resistance, a slot 158 is provided on the locking element 142 through which the connecting pin 150 passes and allows this connecting pin 150 to be displaced transversely to the linear movement direction.

Fig. 12a . 12b and FIGS. 13a, 13b show alternative embodiments to those in FIG Fig. 11 illustrated lifting device 140. In Fig. 12a For example, this alternative lifting device 160 is shown in an initial position. Again, the locking element 162 is used to lock the container or the drawer 88 or to drive the in Fig. 10 illustrated latch 100. A servo motor 164, which with the servo motor 113 from Fig. 10 may be identical, provides the locking element 162 together with energy. For this purpose, the electrical energy of the servomotor 164 is converted into a mechanical linear movement of the locking element 162 via a preferably oval-shaped articulated arm 166.

The oval articulated arm 166 is driven on one side by the servomotor 164 to make a rotational movement. In this case, the other end of the oval articulated arm 166 abuts a plate-like portion 168 of the locking element 162, wherein the locking element 162 is pressed to the outside, namely by a wall 170. The wall 170 may be e.g. the wall of the RFID lock 96 or the wall of the bolt 100. An unillustrated guide shaft can be installed inside the wall 170 in order to ensure a good sliding ability of the locking element 162 in the wall 170.

Between the plate-like portion 168 and the wall 170, a spring 172 is also preferably arranged, which is preferably attached to the outside of the rod-like portion 173 of the locking element 162. Is the locking element 162, as in Fig. 12b shown in its closed position, namely pressed outwards, the spring 172 is compressed and prevents the locking element 162 in its initial position, as in Fig. 12a shown, recoils. The oval articulated arm 166 can thereby advantageously by the servo motor 164 in a position, for example as in Fig. 12b shown to be blocked.

Fig. 13a, 13b show an alternative embodiment of the lifting device 160, wherein an oval articulated arm 174 is supplemented by a further articulated arm 176 and these two articulated arms 174, 176 of the articulated arm 166 from Fig. 12a . 12b replace. The two articulated arms 174, 176 can be dimensioned smaller than the articulated arm 166 Fig. 12a . 12b , In the initial position of the locking element 162, which in Fig. 13a is shown, the latch member 162 is in the retracted position with relaxed spring 172. If the servo motor 164 rotatably moves the articulated arm 174 about an axis, the further articulated arm 176, which is coupled to the articulated arm 174, moves and pushes the locking element 162 through the wall 170 to the outside ( Fig. 13b ). The spring 172 presses together. Again, at least the articulated arm 174 can be held in a locked position by the servo motor 164. By the extension of the locking element 162 and the reception of the locking element 162, for example in the opening 108 (FIG. Fig. 9 ), the drawer can thus advantageously be immovable in the cassette 104 (FIG. Fig. 9 ) are locked. Such an embodiment thus provides protection against unauthorized withdrawal of the drawer 88.

As related to Fig. 8 For example, a pin may be used to control the displaceability of the latch 100. In the Fig. 11, 12a . 12b, 13a, 13b Lifting devices 140, 160 with the locking elements 162 shown can also be used to directly control the displaceability of the bolt 100 (then the locking element 162 would be identical to the pin) or to drive the pin.
