Definitions

  • the invention relates to a locking device with a bolt lock on the door leaf, with a key, which contains electronically readable, stored code information in a cap, a transmitter for inductive transmission of the code information to a receiver on the door frame and an inductively operating energy receiver for receiving Has supply energy from a door frame-side energy transmitter, and with an electromechanical locking device for checking the closing / opening of the bolt lock under control of a control center evaluating the code information.
  • Bolt locks are used in security technology and especially in intrusion detection technology as well as in access control and monitoring systems. These locks are monitored and controlled on the one hand from a common alarm center, and on the other hand can be used to switch the alarm center to an armed or disarmed state. In general, each is an independent lock unit which, in addition to mechanical locking and locking, has to perform the switching and control functions described above. Such locks are also referred to as block locks in intrusion detection technology. Glass breakage detectors, motion or IF detectors or the like can be considered as detectors.
  • the block lock is actuated when leaving a monitored room and thereby the signaling center armed. Conversely, opening of the lock and the associated disarming of the message center can only be carried out by authorized persons, the authorization usually being verified by entering coded information.
  • a line from the movable door leaf, in which the block lock is located, to the fixed part of the door, the door frame, is provided for connection to the signaling center.
  • a flexible cable duct for receiving the cables is led from the door leaf to the door frame and mechanically stabilized with strain relief at both ends.
  • a locking device of the generic type is known from GB-PS 21 58 870.
  • the energy transmitter and the code information receiver are arranged on the door leaf near the lock.
  • the connection to a stationary evaluation unit on the door frame is made via a cable.
  • the control of the electromechanical locking device must take place via a line between the door leaf and the door frame.
  • the invention has for its object to provide a locking device of the type mentioned, in which the effort for installation and assembly is reduced, and which can be used for arming / disarming at a signaling center.
  • the invention is characterized in that no electromechanical or electronic control and monitoring devices need to be installed on the side.
  • a cable or line feed and each other type of galvanic connection between the door frame and door leaf is therefore not necessary.
  • the lock can thus be made purely mechanically and, for example, does not need a locking device, e.g. no magnetic coil and pawl, no electromechanical surface protection against boring, and no electronic assemblies, such as profile cylinder presence monitoring, locking pattern detection and drilling monitoring.
  • the invention thus has the advantage that commercially available standard profile cylinders with commercially available locks could be used in the locking device. In this way, existing systems can also be retrofitted. Since the locking device acts on the door frame side on the free end of the bolt, an adaptation of the bolt to the locking device in question is at most necessary. In cooperation with this locking device and sensors for determining the locking position, it is ensured that the conditions necessary for maintaining the security of the monitored room are maintained, with security against unauthorized attempts at manipulation being carried out by monitoring the code information. The invention can thus also be used to hedge higher and highest risks in accordance with the regulations of the relevant property insurers.
  • a preferred development of the invention consists in the presence of optical and / or acoustic signal transmitters for arming the signaling center. The user can thus immediately check the readiness of the signaling devices.
  • the energy transmitter has an antenna with a predetermined directional characteristic in order to restrict the energy supply to the key to a predetermined, local area.
  • a predetermined directional characteristic in order to restrict the energy supply to the key to a predetermined, local area.
  • the energy transmitter can also be advantageous for the energy transmitter to transmit permanently. This ensures that the key-side units are ready for operation as soon as they are in their intended location, i.e. get the lock cylinder. Switching on and off takes place automatically and depends solely on whether the units are adequately supplied with energy.
  • a preferred alternative is that the transmission time of the energy transmitter is controlled by the reporting center.
  • the access times or the arming / disarming intervals can be fixed or optionally specified as required.
  • the energy transmitter is only activated when the bolt is excluded. Since this position identifies the arming status of the signaling center, for the changeover of which a query of the code information is necessary, the activation of the transmitter in this status is sufficient. In the other bolt position, which is characteristic of the unset state, code information monitoring is not absolutely necessary, since actuation of the lock brings about a secure state of the alarm center, namely the arming.
  • the security of the locking device is increased in that when the sensor is activated, the start of a time interval is defined which limits the query time of the code information by the signaling center. If the code information is not received correctly within this time grid, further actuation of the bolt by the locking device is prevented.
  • the bolt movement can be monitored in both directions, so that on the one hand it is excluded that the alarm center is armed or disarmed without authorization. In the former case, this could lead to undesirable false alarms. With regard to the second case, this measure precludes the manipulation of the code information and trying out different alternatives which can unjustifiably disarm the alarm center.
  • the locking device consists of a pawl operated by an electromagnetic coil and that the free end of the bolt is provided with a locking edge for receiving the pawl.
  • the bolt can therefore only be moved if it is released by the pawl.
  • the key-side receiving unit consists of an oscillating circuit with a rectifier connected downstream, and that the energy transmitter for energy transmission transmits a signal of a predetermined frequency for conversion into a DC voltage.
  • the code information transmitted on the key side consists of pulse series with binary encryption, that these pulse series are transmitted at high frequency and that a corresponding high-frequency receiver with a downstream rectifier arrangement for converting the pulse series into equivalent direct current pulses is present on the door frame side.
  • a power amplifier may be connected downstream of the rectifier arrangement.
  • a part of the free end of a door leaf 18 and the associated part of a door frame 19 is shown in each case in partial longitudinal section in such a way that details can be seen on a locking device arranged in the door leaf 18 and in the door frame 19, which are otherwise otherwise are enclosed and covered by a housing cover and covers of the door leaf 18 and the door frame 19.
  • the locking device consists of a bolt lock 1 which is arranged in a corresponding recess in the door leaf 18 and is screwed to the front face of the door leaf 18 via a faceplate 23.
  • the bolt lock comprises a lock cylinder 24 which, in the selected form of representation, runs perpendicular to the plane of the drawing.
  • the latch 2 is shown in its closed position in FIG. 1, in which it is received by a latch holder 20 in the door frame 19.
  • the bolt 2 is in engagement with a striking plate 4, so that opening the door leaf 18 is not possible.
  • 34 is a trap.
  • an electromechanical locking device controlled by a signaling center (not shown), which here consists, for example, of an electromagnet 5 and a pawl 6 spring-loaded by the electromagnet 5.
  • the pawl 6 is provided with a locking lug 25 for engagement with a locking edge 26 at the free end of the bolt 2. In the extended state of the bolt 2, it is held by the locking device 29. Resetting is only possible after approval by the reporting center, i.e. possible by energizing the electromagnet 5.
  • FIG. 1 is limited to the reproduction of a single sensor which detects the locked position of the bolt 2.
  • a predetermined deadbolt travel can also be recorded, which is to be evaluated in the signaling center, as shown in FIG. 3.
  • a device for carrying out an authorization check for example a keypad for entering an alphanumeric code or a magnetic card reader, the evaluation unit of which is provided with the reference number 9.
  • Another device for performing an authorization check is as follows: described in particular in connection with FIG. 2.
  • the key user is identified and converted into an equivalent signal in the evaluation unit 9, which is transmitted to the signaling center via lines 27. If the person concerned is authorized, the locking device 29 is activated via the signaling center and the bolt 2 is released for closing. This approval is only given if it is operated properly and all requirements are met, which experts also refer to as inevitability.
  • the locking or locking process and arming of the signaling center are carried out analogously. If all conditions for the inevitability of a security system, for example an intrusion alarm system, are met and the operator is authorized to operate it, the coil 5 is briefly energized under control of the alarm center, the pawl 6 picks up and the bolt 2 can be completely excluded. The excluded bolt 2 is detected by the sensor 7 and then the information relating to the bolt position is transmitted to the alarm center via the alarm lines 39. The information derived from the sensor 7 about the end position of the bolt can be used, for example, for arming / disarming the signaling center. The arming is indicated by an optical and / or acoustic signal generator 35 or 36.
  • the pawl 6 does not release the bolt path, so that the bolt 2 cannot be moved completely into the bolt receptacle 2.
  • no corresponding signal is forwarded from the sensor 7 to the signaling center, so that the alarm center is not switched.
  • the alarm center would typically be disarmed as long as there is an authorized person in the monitored area, in which the device for the authorization check is also arranged. If the authorized person leaves this area, the alarm center must be armed.
  • an electronic authorization check is carried out using key 22.
  • an electronic coding device, an electronic control unit and a high-frequency transmitter and supply units are mounted on the key 22 in a cap 8 on the key head. The details are described below with reference to FIG. 2.
  • FIG. 2 shows that the electronic circuit arrangement 30 located in the key cap 8 transmits a high-frequency pulse sequence 28 to the evaluation unit 9 for wireless data transmission. Furthermore, the circuit arrangement 30 receives energy wirelessly from an energy transmitter 10 on the door frame side. A galvanic connection is not present.
  • the energy transmitter 10 transmits a predetermined frequency f1, which is received by a key-side resonant circuit 11 and is converted in a rectifier 12 into a direct voltage, which is stored in a capacitor 31 as the operating voltage U B for supplying the circuit arrangement 30.
  • a predetermined frequency f1 which is received by a key-side resonant circuit 11 and is converted in a rectifier 12 into a direct voltage, which is stored in a capacitor 31 as the operating voltage U B for supplying the circuit arrangement 30.
  • the energy transmitter 10 works permanently and that it is only activated for a short time, for example only when the bar 2 was excluded.
  • a high-frequency transmitter 13, an electronic control circuit 14 and a program carrier 15 are supplied with the operating voltage U B.
  • the circuit 14 can be designed, for example, as a customer-specific integrated circuit.
  • PROMs, EPRROMs or EEPROMs can be used as program carriers 15, which can also be integrated in the circuit 14.
  • An identification code is stored in the program carrier 15 and can also be deleted, changed or rewritten if necessary.
  • a serial data sequence containing the identification code is generated under control of the circuit 14 and transmitted asynchronously to the evaluation unit 9 with the start and stop bit in a known manner.
  • the generated direct current data telegram activates the cycle of the pending pulse train of the high-frequency transmitter 13.
  • the circuits of the evaluation unit 9 and the associated receiving devices can optionally be implemented with discrete IC technology and microprocessor or customer-specific, integrated circuit. They include a high-frequency transmitter 16 for receiving the serial pulse train emitted by the high-frequency transmitter 13. The received high-frequency pulses are converted into equivalent direct current pulses for further processing and evaluation.
  • high-frequency receiver 16 has signal preprocessing 17 for processing downstream of the voltage impulses so that these can be transmitted via cable to the signaling center over a greater distance.
  • the energy transmitter 10 can be arranged separately in the region of the door frame 19 or can be combined with the other electronic devices on the door frame side.
  • the authorization check takes place as soon as the key 22 reaches the reception area of the energy transmitter 10 on the one hand and the radio frequency receiver 16 on the other hand enters the reception area of the radio frequency transmitter 13. These conditions exist at least when the key 22 is inserted into the locking cylinder 24. If authorization is given, the coil 5 is energized in the manner already described and the bolt 2 is released via the pawl 6.
  • FIG. 3 illustrates a variant of the locking device as shown in FIG. 1.
  • the same parts are provided with the same reference numerals.
  • the bolt 2 ⁇ is formed two-speed.
  • the corresponding bolt positions are shown in dash-dot lines.
  • a first query sensor 37 is actuated. If at the same time the inevitability of the signaling center is fulfilled, the receiver 16 is released to receive the code information for a predetermined time interval. Alternatively or additionally, it can also be provided that the energy transmitter 10 is put into operation within this time interval.
  • the pawl 6 ⁇ releases the further bolt path.
  • a further interrogation sensor 38 is then activated when the bolt 2 ⁇ assumes its end position. All of these conditions result in the alarm center being armed.
  • the pawl 6 ⁇ remains locked and the signaling center cannot be armed.
  • the procedure is analogous for a digestion process.
  • the latch 2 ⁇ can only be completely closed if the code information is properly identified after the query sensor 37 has been actuated. Otherwise, the pawl 6 ⁇ holds the bolt, whereby the alarm center remains armed.
