Description

[0001] LOCKING DEVICE AS WELL AS SECURITY SYSTEM AND METHOD COMPRISING THE LOCKING DEVICE FIELD OF THE INVENTION The present invention relates generally to a locking device for securely locking a movable component, in particular a door, to a security system comprising the locking device, and to a method comprising the locking device. BACKGROUND OF THE INVENTION Locking devices for securely locking a movable component, such as a door or a window, are generally known. For example, the status of a door can be monitored by detecting the bolt position. When the bolt is in the locked position, the door is closed, and when the bolt is in an open position, the door is open. However, this type of monitoring is susceptible to manipulation, malfunctions, or improper operation.If the latch is in the locked position but the door is not closed, the monitoring system is still given the impression that the door is closed. For this reason, door contacts are often installed in doors for status monitoring purposes. These are designed to detect whether the door is actually open or closed. This is intended to increase security. However, such detectors are often installed in easily accessible places on the door or door frame, making them easy to tamper with. Easily accessible door contacts can be easily tampered with, especially when the door is open. Retrofit solutions are particularly vulnerable to this. If the door contact is to be installed in a place that is difficult to access, this is often only possible with complex installation or extensive preparatory work. Door contacts can, for example, be equipped with a magnet. The system can distinguish whether the magnet is in position or not.A signal is output depending on the status. This means that only the presence of a simple element can be detected. This system can be easily tricked into believing that the magnet is in the specified position, for example using a different magnet. Particularly in highly secure systems such as safes, the locking device must be protected as best as possible against manipulation, malfunctions, or negligent operation. For example, in the event of damage, it must also be proven that the damage was not caused by a faulty or inadequately secured locking device. The object of the present invention is therefore to provide an improved locking device, a security system, and a method in which the disadvantages and problems mentioned above are at least partially reduced.SUMMARY OF THE INVENTION This object is achieved by a locking device according to claim 1, a security system according to claim 14 and a method according to claim 15.

The identifier can be a magnet arrangement. The magnet arrangement can be individual. Encryption can be increased by varying the magnet arrangement. In the case where the identifier is a magnet arrangement, the second monitoring component can be a sensor. The sensor can be, for example, a magnetoresistive sensor. The sensor can be a sensor arrangement.When the bolt with the magnet arrangement approaches the sensor, an external magnetic field is applied and the electrical resistance changes as a result. Using the identifier, the monitoring arrangement can detect the closed position of the bolt. Using the identifier, the monitoring arrangement can detect the correct bolt in the bolt receptacle. This can increase the security of the locking device. There are embodiments in which the identifier can be read by the second monitoring component within a response range of the second monitoring component. The response range can correspond to a range. The response range can be the range in which the second monitoring component is able to read the identifier. Outside the response range, the identifier cannot be read. The response range can be a predefined range. The response range can be designed such that it can be activated and / or deactivated.The identifier can be read contactlessly by the second monitoring component within a response range of the second monitoring component. The identifier can be read contact-based by the second monitoring component within a response range of the second monitoring component. The second monitoring component can be connected to the controller. The second monitoring component can forward the read-out identifier to the controller for processing. The identifier can be encrypted after reading. The identifier can be encrypted by the converter. The identifier can be output to the controller in encrypted form.

This can prevent the identifier from being read, for example, when the bolt is in the closed position.There are embodiments in which the response range of the second monitoring component is within the bolt receptacle. The response range can be in the area of ​​the bolt receptacle. The response range can be designed such that the identifier can only be read when the first monitoring component is arranged in the immediate vicinity of the second monitoring component. The response range can be designed such that the identifier can only be read when the first monitoring component contacts the second monitoring component. As a result, the identifier can only be read when the bolt is in the closed position within the bolt receptacle.

The energy source and the second monitoring component can be located in a spatially separate environment. The energy source of the second monitoring component can supply the first monitoring component with energy without contact. The first monitoring component can be designed in such a way that the identifier can be read as long as the first monitoring component is supplied with energy. If the first monitoring component is not supplied with energy, the identifier cannot be read.This can, for example, prevent the identifier from being read when the bolt is in an open position and not in the bolt receptacle. The contactless power supply can be provided via non-wired electromagnetic fields. The power supply can be inductive. The first monitoring component can be inductively coupled to the second monitoring component in the response range.

The RFID transponder can only be read in the response range of the RFID reader.A frequency range can be selected according to a requirement profile, for example, the reading distance, the transmission rate, or another requirement. The RFID transponder can be a low-frequency (LF) transponder. The frequency range can be selected, for example, between 30 kHz and 300 kHz. This can result in a feasible reading distance of less than one centimeter. The RFID transponder can be a high-frequency (HF) transponder. For example, a frequency of 6.78 MHz, 13.56 MHz, or 27.125 MHz can be selected. This can increase the reading distance compared to the low-frequency transponder.

The RFID transponder and RFID reading device can be coupled as a close-coupling system.The maximum distance between the RFID transponder and the RFID reader can be one centimeter.

The security feature 35 is transmitted (schematically shown as a dashed line). The phototransistor 31b is activated. The release position F is detected. The activated phototransistor 31b activates the antenna 24b of the RFID transponder 24. The activated antenna 24b allows the RFID transponder 24 to be read. The phototransistor 31b activates the monitoring device 21. The identifier 27 is within the response range of the RFID reader 26. The RFID reader 26 reads the identifier 27 of the RFID transponder 24. The read identifier 27 corresponds to the specified identifier. In this sequence, the closed position C of the bolt 5 in the bolt receptacle 9 is detected. The monitoring arrangement 20 outputs the closing signal 51 to the controller 50.
