Description

locking system

The invention relates to a closure system comprising an electromechanical closure, in particular Schwenkhebel-, rotary latch or compression closure, the lock can be opened by a current flowing through a solenoid coil or motor current signal.

Such a closure system is already out of the DE 20 2007 007 723 U1 known. A disadvantage of the prior art is that the operating power for the electronic part, which is housed in the trough for the pivot lever and must be supplied with the current flowing through it to open the shutter in a complicated manner by a backup battery or by a power supply, which power supply for the power connection requires a breakthrough in the door.

The object of the invention is to provide an arrangement which avoids these disadvantages and provides a power supply that is not based on its own batteries or requires a power connection that is often not available or can not be created in a simple manner.

The object is achieved by the fact that the current signal is transmitted by wireless energy transmission from a point outside the shutter (ie user side) to a point within the shutter (ie cabinet side).

According to one embodiment of the invention, the locking system locks a cabinet door or the like. Made of sheet metal or plastic control cabinet, the location outside the locking system is a location on the door leaf outer surface.

According to yet another embodiment of the invention, this location located outside the closure consists of a thin sheet metal wall or sheet metal door with an opening which is closed by a plastic frame or insert, or alternatively from a plastic door with a reduced wall thickness, the one on the outside Recess forms.

According to yet another further development, the frame or the insert, or alternatively a recess in the outside, forms an outwardly open space into which a smartphone or a Bluetooth mobile phone or the like can be received.

In a further development, the smartphone or the Bluetooth mobile phone is held by a Klipseinrichtung in the cavity.

According to yet another embodiment, the point inside the closure on the inside of the frame or insert and at this point is a converter for the conversion of radiated by the smartphone or the Bluetooth mobile phone in broadcast radio frequency arranged in direct current.

The invention will be explained in more detail by means of exemplary embodiments, which are illustrated in the drawings.

12C a sectional view taken along the line AA of 12A ,

So is in perspective exploded view in 1 a closure system 10 shown, which has an electromechanical closure, here a swivel lever lock 12 includes. The closure 12 is on a door leaf 14 mounted and the electromechanical shutter 12 includes a trough 16 with pivoting mounted therein operation 18 that makes it possible for an actuating shaft 20 to twist. The operating lever 18 can into the hollow 16 be pivoted and locked in this pivoted state by a locking mechanism 22 , The hollow 16 is on the outside surface 14 of the door leaf 24 assembled. The actuating shaft 20 and other projecting areas 26 the hollow 16 are through openings 28 . 30 in the door leaf 24 guided and reach over the rear surface 32 of the door leaf 14 out. From the projecting area 26 the hollow 16 goes a protected cable 32 off, for connection with other electronic components of the switchgear on the back of the door leaf 14 ,

To the locking system 10 to be able to lock, a piston is moved via an armature (magnet) when passing current and z. B. pushed a pin into an opening, wherein a blockage takes place, either the pivot lever within the trough or the push rod within the guide for the push rod. The current which is necessary for the actuation of the magnet in the coil, according to the invention is not supplied via a battery or a mains connection, but by wireless energy transmission from a point outside the closure, on the front 14 the door leaf to a point inside the closure or on the back 32 of the door leaf 24 , Often one manufactures control cabinets made of sheet steel, so that it is expedient in the thin metal wall 24 to provide a breakthrough as metal shields radio frequency energy. Such an opening 34 can then subsequently through a plastic frame or plastic insert 36 be closed. The reason for this measure is that a metal hinders the transfer of energy, while plastic usually allows the transfer.

In the insert 36 or in the frame 34 It is possible to use transmission electronics which transmit electrical energy in the form of high-frequency radiation to the other side of the door leaf, through the aperture, to a receiving device on the other side 40 to be caught. The receiving device may for example have the form of a coil. The transmitting device 38 Can be from a smartphone or Bluetooth phone 42 be formed. By emanating from the smartphone radiation high frequency energy can be transmitted by the receiving device 40 is converted into direct current, for example, or it can also be simultaneously transmitted data that are needed in the locking system, for example, to open the shutter, if a corresponding message is received by the smartphone and passed on.

The transmission area 34 , the frame 36 and the use 38 can form an outwardly open space in which a smartphone or a Bluetooth phone is receivable, on the other hand can also serve as an alternative deepening. The radiation power emitted by the smartphone or other devices for generating high-frequency energy penetrates through the plastic insert and impinges on the receiving device, for example in the form of a coil 40 , In the region of the coil, a converter for the conversion of the collected by the coil high-frequency energy can be arranged in DC energy. An electronics-activated locking system for the power supply gets the access permit, whereby operation without connection to the power grid is possible, which is used for installation safety and installation regardless of the power grid is possible.

The electromechanical locking system is protected against vandalism, works in the field of view or in the non-visible area and allows activation and release only via authorization procedure.

Claim 1 thus relates to an electromechanical locking system (pivot lever, rotary latch, compression lock, etc.), which is operated smart and using external, contactless energy transfer.

The system components are explained below.

data transfer

An embedded system (smartphone / laptop / man-machine interface) is used on the user side of the control, communication and access control with the cabinet-side remote station. Authorization takes place via the synchronization of access rights, for example by transmission of access codes. Hierarchical code structures and classifications (master key, groupings, one-time codes) are possible. These codes are transmitted via user input manually or via the controls of the software. Without existing user interface, the code is automatically transmitted when the transmitter unit is coupled to the receiver unit by the transmitter unit. A secure, encrypted connection is established between the embedded system and the communication module of the cabinet unit via a communication protocol.

The data transmission uses a secure radio connection (for example, Bluetooth).

The embedded system (transmitter) logs any access attempts and events made with this system (transmitter).

Live updates, such as updates and access rights adjustments, can be made on-demand via the mobile network.

management software

Higher-level management software is used for the central control and administration of user accounts, module lock management, access / code assignment and the illustration of the locking system.

Transmitter / transmitter electronics

In a further embodiment, the transmission electronics are connected via a physical interface (plug connection) to the embedded system (smartphone / laptop / human-machine interface) in order to use its user interface, energy storage and radio module. Another version integrates the entire transmitter electronics including the battery into a single module, which carries out the energy transfer to deactivation after the activation process.

A further embodiment extends the transmitting device such that it can receive current induced by the coil, so that the connected energy store of the transmitting unit can be charged wirelessly in accordance with the transmission principle.

Receiver / receiver electronics

The receiver electronics are located inside the application and have no visible or physical interface to the outside. The receiving device is mounted internally in the transmission area, which allows optimized transmission efficiency of energy and data.

The receiver electronics are based on the same technology as the transmitter module, so that a coupling and, consequently, an energy transfer to the internal system is possible. A permanent connection to a power supply network is not necessary. Furthermore, the receiver electronics has a radio module (for example a Bluetooth module) in order to set up a communication between a microcontroller and the software / app after activation by the energy intake.

The intelligence in this system acts as a partner of the embedded system of the mobile unit.

The receiver electronics supply the electromechanical shutter with energy and switch it - after a successful authorization process - free.
