Description

The invention relates to a locking device, in particular for furniture, with a locking mechanism and with an electronic control for the locking mechanism.

From the DE 11 2016 004 841 T5 Electronic locking devices for furniture, cupboards or lockers are known which have a housing, a locking element and a power supply module. A battery for powering the locking element is located in the power supply module. The power supply module can be removed for quick battery replacement. In the known electronic locking devices, the exchange of data between a transmitter and the electronic lock for opening the lockers takes place only via defined communication channels.

In contrast, it is the object of the invention to provide a flexible locking device.

This object is achieved according to the invention by a locking device, in particular for furniture, with a locking mechanism, with a control for the locking mechanism, with at least one internal data receiver connected to the control for wirelessly receiving access data of the locking device, with at least one connected to the control, internal data interface for the wireless reception and transmission of access and / or control data and event logging of the locking device, and with at least one connection connected to the control for an external data receiver or for an external data input device, the control being programmed, the locking mechanism on the basis of that open or close internal data receiver, access data received from the internal data interface, from the external data receiver or from the external data input device.

Various additional external devices can be connected through the connection, so that the data transfer for opening and / or closing the locking device can take place on different communication channels. The controller has an integrated processor system, in particular in the form of a Smart Module Core (SMC) module. The lock is used in particular for furniture or also for revolving doors, flaps, sliding doors, drawers, roller shutters, wardrobes, lockers, lockers or lockers with doors made of wood or HPL (high pressure laminates) (for metal furniture via external RFID antenna). The locking device can be integrated into a wireless local area network or mesh WLAN network, via which the locking device can be connected to other physical or virtual objects.

In an advantageous embodiment of the invention, the internal and / or external data receiver is a radio frequency identification (RFID) receiver and the internal data interface is an example of a low power wireless radio in the 2.45 GHz ISM band (BLE, BLE mesh, thread, Zigbee) Protocol standard), in particular as a Bluetooth Low Energy (BLE) data interface with a BLE antenna. This enables wireless data exchange with RFID transponders and with smartphones over short distances to activate the locking mechanism. Data is exchanged via a low power wireless antenna at 2.4 GHz and via the RFID data receiver, in particular at 13.56 MHz. What is new is the design of the Low Power Wireless Radio in such a way that the appropriate software for the SMC processor system enables data communication to be specific and simultaneous via different communication standards. The data communication can thus be optimized for loT communication via threat, for smartphone via BLE and for building automation, for example via Zigbee. Logically and securely separated authentication and channel-dependent encryption methods (seed, algorithms, encryption key) can be used to form sequentially and / or hierarchically superimposed rules for control, administration and selective data communication. In particular, this invention results in new, secure methods for networking sensors and actuators from different systems / trades (lighting technology, air conditioning technology, alarm systems, fire alarm systems) at the field level, without the need for complex protocol translators (gateways and server applications).

The external data input device can be designed as a card reader, fingerprint reader or keypad (the latter also possible as a handle or design element) or can be a smart phone with a corresponding app for recording the biometric or mental identification features.

The locking device according to the invention preferably has an internal battery for supplying power to the locking device and / or at least one power supply connected to the controller for an external power supply.

In a preferred embodiment, the locking device has at least one sensor for querying the closed state of the locking mechanism, to which the control is connected. Via a sensor for Bolt monitoring, for example a light barrier and / or a reed switch, the closing status can be detected and controlled by the control at any time, or attempts at manipulation can be detected. In particular, the locking device can trigger an alarm when an attempt is made to open the lock by force. In addition to the locking mechanism, the sensors can also be used to monitor the locking status of the locking point to be locked.

In a further embodiment of the invention, the control is designed to enter operating parameters of the furniture lock. For example, door open times or the operating modes of the locking device, e.g. keyed operation, latch lock operation or bolt lock operation, and the interaction with other sensors and actuators can be set.

The invention also relates to a system with a plurality of locking devices as configured above, which are connected to one another by a wireless network, such as a mesh WLAN network. The wireless network is preferably formed from the internal data interfaces of the locking devices. At least one of the locking devices can advantageously be programmed as a master locking device and the other locking devices can be programmed as slave locking devices, the slave locking devices for opening and closing only being controllable by the master locking device. In a master / slave operation, the locking devices, in particular via BLE, can be hierarchically switched or cascaded. A cable connection, as known from the prior art, is no longer required. This enables various applications, such as a different or identical operation of the individual locking points in mobile furniture, for example lock functions with a defined locking sequence.

Further advantages of the invention result from the description, the claims and the drawing. Likewise, the features mentioned above and those listed further can be used individually or in combination in any combination. The embodiments shown and described are not to be understood as an exhaustive list, but rather have an exemplary character for the description of the invention.
