Definitions

  • the invention relates to electromechanical operating devices which are controlled by a code so as to allow access to a given device only to authorized persons; these devices generally include a control unit located near the device to be monitored and which comprises a code entry interface connected to a comparator which also receives the content of a memory containing an actuation code; this comparator controls an electrical device for actuating the controlled device.
  • a monitoring unit located remotely and connected to the control unit by a transmission device such as a cable makes it possible to monitor access to the controlled device.
  • the actuation code can be entered by means of a keyboard, a badge bearing the code, a magnetic card or even a photoelectric cell emitting a code in light form, for example an infrared cell. .
  • Unauthorized persons who want to force mechanical access to the device controlled by the device described above creates shocks to the device and its control unit, for example by trying to break a window or a panel in the door control case; these people can also try to open or tear off the control unit in order to access the coding device or the conductor of the electrical actuation device. Even if they are noisy, such actions are not perceived by the surveillance unit which is far from controlled access. However, a breach of the controlled access requires a relatively long time and it is desirable that the surveillance unit be notified at the start of such an attempt in order to be able to intervene before the access has been forced.
  • the present invention therefore relates to an electromechanical operating device of the type mentioned above which comprises a device making it possible to warn the monitoring unit of any attempt to force the controlled access.
  • the electromechanical operating device is notably remarkable in that the control unit comprises a shock detection element and a tear detection element which are connected so as to produce a logic circuit OR triggering the emission of an alarm which is transmitted to the monitoring unit. In this way, from the start of the break-in attempt, the alarm is given to the monitoring unit which can then intervene.
  • This alarm can also be made perceptible at the controlled opening, for example in audible and / or optical form, and so as to discourage people attempting to break in.
  • control unit comprises a device for storing said alarm, said storing device being remotely reset by the monitoring unit. This allows in particular to eliminate an alarm due to an isolated accidental shock.
  • the controlled device may create shocks which will be perceived by the shock detector element; this is the case in particular in the case where the controlled device is a door, the closing of which can create shocks at the level of the control unit, the electromechanical operating device controlling either an electric lock or directly a motor of door opening.
  • the control unit further comprises an element for detecting the state of closing of the door controlled by the lock, this sensor element inhibiting the alarm signal supplied by the element for detecting shocks or the tear-off detection element for a predetermined period following the closing of the door.
  • this door closing detector element controls the locking of the lock. This can for example be achieved by the fact that the electrical opening device, said memory device being reset to zero by said element for detecting the closing of the door.
  • the electric strike lock shown in the figure comprises a control unit 1 arranged near the lock to be controlled, for example on the door protecting the lock and a monitoring unit 2 arranged remotely and connected to the control unit 1 by a transmission idspositif constituted for example by a cable.
  • control unit 1 comprises an input interface 2 which may include a keyboard or be controlled by a coding device such as a magnetic card, a badge or an optical cell with infrared code.
  • the code provided by this interface 2 set sent to a comparator 3 which also receives an opening code recorded in electronic form in a memory 4.
  • the output of the comparator 3 controls an electric opening device constituted by the electric strike 5.
  • control unit 1 comprises a storage device 6 which stores the opening order provided by the comparator 3.
  • the control unit also comprises a command and control circuit 7 which is connected to the monitoring unit 2 so as to allow control and monitoring 2 so as to allow remote control and monitoring of the door supporting the electric lock.
  • the shock detector consists of a switch 8 comprising a movable contact sensitive to shock and the pull-out detector consists of a switch 9 comprising at least one fixed contact secured to the base or the support of the control unit and a movable contact secured to a removable part of the control unit or of the control unit or the control unit itself.
  • These two switches are connected in series with a resistor 11, the assembly being in parallel on the terminals of a capacitor 12 which is connected on the one hand to a positive voltage source via another resistor 13 and secondly, to ground.
  • a circuit is obtained carrying out the logic OR function which provides at the output of a reversing gate 14 a signal of level 0 when at least one of the switches 8 or 9 is open.
  • the alarm signal obtained is stored in a memory device 15 and then sent to the monitoring unit 2 for example via a line 16.
  • the control unit 1 also includes a door closing detector element constituted for example by a contact 17 which is closed when the door is closed.
  • This door closing contact 17 is arranged in a circuit similar to that of the shock and breakout detector elements and comprising a series resistor 18, a capacitor 19 and a resistor 21 connected to a power source.
  • the output of the circuit thus formed which goes to a low level when the contact 17 closes is connected for example to a flip-flop 22 of the type controlled by a falling edge.
  • the door closing signal obtained controls a time delay circuit 23, the output signal of which activates a validation circuit 24, constituted for example by a logic gate so as to block the passage of the alarm signal when the time delayed closing signal door is present.
  • the timing circuit 23 controls the resetting of the storage device 6 when the timed door closing signal disappears.
  • the reclosing and / or relocking command is only given at the end of the circuit 23 time delay and only if the door has remained closed during this time delay. This makes it possible to avoid all maneuvers or attempts at fraud by a reclosing followed by a very rapid reopening before the bolts have been able to function.
  • the circuit 15 for memorizing the shock or breakout alarm signal is reset to zero by the monitoring unit 2, for example via a line 25.
  • any opening of one of the contacts 8 or 9 causes a shock or breakout alarm signal which is transmitted by the validation circuit 24 to memory 15 then to the monitoring unit.
  • the personnel present at this monitoring unit can cancel this alarm by acting on the reset of memory 15. and if no other shocks or tears occur, the alarm disappears.
  • This alarm can be produced visually or audibly at the door controlled by the lock so as to dissuade people trying to force the door.
  • the contact 17 When the door has been opened, for example by an authorized person, the contact 17 is open and when the door closes, its contact also closes, which creates a door closing signal by means of rocker 22.
  • This delayed signal in the delay circuit 23 blocks the passage of the shock or breakout alarm signal through the validation circuit 24 and there is therefore no emission of a shock alarm signal or tears.
  • the timing of circuit 23 is set to a low value, for example one second.
  • the disappearance of the timed door closing signal causes the storage circuit 6 to be reset to zero, which eliminates the order to open the door sent to the electric strike 5; moreover, the disappearance of the timed door closing signal causes the issuance of an order to close the bolt for locking the lock 5.
  • the shock detector comprises a device distinguishing the shocks of small amplitude from the shocks of large amplitude; this can for example be achieved by measuring the opening time of the switch 8.
  • the surveillance device being in the pavilion, this device is particularly advantageous.
  • the intercom microphones can be used to carry out the local audible alarm.
  • the invention allows the emission of a shock or breakout alarm signal for any shock or breakout of the control unit resulting from an attempted break-in, this alarm being inhibited during the door closing.
