  • the present invention relates to electronic operating devices, the actuation of which is obtained by means of a code and which are intended to control an apparatus controlling access, such as an electric strike lock or a door opening motor. so as to allow access only to authorized persons knowing this code.
  • these electronic operating devices comprise on the one hand a control unit arranged in the vicinity of the device to be controlled and which comprises an electronic device which checks the code supplied by the users and provides, in the event of the correct code, a control signal of the electrical device for actuating the device and, on the other hand, a monitoring unit arranged remotely and which makes it possible to command and / or control said access.
  • Such devices are constituted for example by locks controlled by a code which are intended in particular for controlling the opening of the rooms of a hotel or a motel and include a coding unit which is arranged at a distance from the door to be controlled, for example at the hotel office, and which includes a remote coding device, connected to the control unit.

  • a remote coding device which is arranged at a distance from the door to be controlled, for example at the hotel office, and which includes a remote coding device, connected to the control unit.
  • Such an electric strike is described in particular in French patent 2,224,629; the remote coding device allows you to change the opening code of each door at will from the hotel office. This therefore requires that each client come to code the door to their room at the hotel office, which constitutes a constraint, in particular in the case of a motel; in addition, the customer is often obliged to dial his code in the presence of hotel staff and there is no
  • the invention therefore relates to an electromechanical control device controlled by a code that can be modified remotely of the aforementioned type which allows coding "on the spot" by the user. Therefore, in the case of a hotel, the customer can enter his room his opening code that he will be the only one to know for the duration of his stay, the hotel staff being able to give his own code at the end of the customer's stay.
  • control unit further comprises a selector device controlled by the remote coding unit and which selectively transmits to the memory a code supplied by the input interface or sent by the coding unit.
  • control unit comprises a multiplexer receiving on the one hand the output of the input interface, and on the other hand, the code sent by the coding unit, the output of the multiplexer being sent to the memory write input and said multiplexer being controlled from the remote coding unit.
  • control unit comprises an OR logic circuit receiving on the one hand a signal indicating the supply of a code digit by the input interface, and on the other hand, a remote coding order and the output of which is connected to the memory write command port.
  • the central unit comprises a device for counting the code digits supplied by the input interface, the output of said counter being connected to a limiter of the number of digits of the code which controls the resetting said input digit counter to a predetermined number of code digits supplied by said interface.
  • the output of said limiter is connected on the one hand to an input code counter, and, on the other hand, to a timing circuit and the control unit comprises an AND logic circuit receiving on the one hand the output of said timing circuit and, on the other hand, a signal corresponding to a predetermined number of codes, the output of said logic circuit AND providing an alarm of false codes.
  • Figure 1 shows the control unit of the electric strike which has an input interface consisting code reader 1, for example a keyboard, an optical, magnetic or infrared code reader followed by a binary coder 2 whose output is sent to one of the inputs of a comparator 3 which receives on its other input the content of a memory 4.

  • the control unit comprises a selector controlled by the coding unit and which makes it possible to send selectively to memory 4, that is to say the code supplied by the coder 2 connected to the output of the interface 1, ie the code supplied by the counter 11.
  • This selector device essentially comprises a multiplexer 12 controlled from the coding unit via a line 13 and which receives on the one hand the output of the coder 2, and on the other hand, the output of the counter 11, the output of the multiplexer 12 being sent to the write input port of the memory 4.
  • An OR logic circuit 14 receives on the one hand a signal corresponding to a remote coding, namely the output of the logic circuit 8 and, on the other hand, a signal corresponding to a coding on the keyboard 1, said signal being supplied by the coder 2; the output of this OR logic circuit 14 is sent to the write control port of memory 4.
  • the output of the logic circuit 8 is also sent to a counter for the number of input slots 10, the output of which is sent to a multiplexer 15.
  • An input digit counter 16 is connected to the output of the encoder 2; the output of this counter is sent on the one hand to a circuit limiting the number of digits of the code 17, and, on the other hand, to the second input of the multiplexer 15.
  • the resetting of the counter 16 is controlled by the limiter 17.
  • the comparison logic mentioned above which is controlled by the comparator 3 is constituted by a counter of the number of correct digits 18 followed by a comparator 19 of the number of correct digits to the number of the digit limiter 17.
  • the output of the comparator 19 commands the electric strike proper 5 via an OR logic circuit 20 which can also receive an opening command from the coding unit via a line 21.
  • the line signal 21 can be an AND function between a validation of the coding unit and a signal coming from any switch or push button fixed near the keyboard. This "free entry" function makes it possible to activate the electromechanical mechanism 5 without having to supply a code to the comparator 3.
  • the keyboard 1 comprises a reset key R which actuates on the one hand a timed switch 22 of the lighting 23 of the keyboard, and on the other hand, the reset of the counter 16 of the number of digits entered and of the counter 18 of the number of correct digits.
  • FIG. 2 represents an embodiment of the circuit limiting the number of digits such as circuit 17.
  • the counter 16 for the number of input digits which comprise the output port corresponding to the four binary coding bits which are sent to the multiplexer 15.
  • two of these outputs of the counter 16 or one of them are sent to an AND logic circuit 34, and the output of this AND circuit 34 being sent to the reset port of the counter 16 via a second AND logic circuit 35 also receiving the reset circuit coming from the actuation of the key. reset keyboard 1 or an equivalent signal from any code reader.
  • these AND circuits are in fact NAND circuits.
  • circuit 34 the number of digits entered can be limited to any binary number comprising one or two bits equal to 1, that is to say to decimal numbers 1,2,3,4,5,6,8, 9, 10, 12 and 16.
  • a device making it possible to generate an alarm of "false codes" when a predetermined number of erroneous codes are dialed on the keyboard 1.
  • This device comprises a timeout 24 and a counter 25 for entry codes; triggering of timer 24 is controlled by circuit 17 limiting the number of digits of the code whose output pulses are counted by counter 25.
  • the output of timer 24 and the input code counter 25 are sent to a door AND logic 26 whose output constitutes the signal of false codes.
  • the counter 25 of false codes is reset to zero at the end of the timed signal supplied by the timer 24; moreover, the time delay 24 is inhibited by the command signal to open the electric strike supplied by the OR logic gate 20.
  • the comparator 3 controls the counter 18; when the number of successive correct digits counted by the counter 18 corresponds to the number displayed in the limiter 19, that is to say to the number of digits of the code, this limiter circuit controls the supply of the electric strike 5 by the intermediate of the OR gate 20. If the two digits sent to the comparator 3 are not equal, the output of the comparator commands the reset of the counter 18 of correct digits for example by means of an inverting gate 27.
  • the OR logic gate 20 only delivers a validation signal if all the digits of the code have been successively dialed in a predetermined order.
  • the remote modification of the code contained in the memory 4 is carried out by sending a continuous remote control order on line 6 while slots of variable width are sent on line 7.
  • the coincidence of these slots with remote coding order command through from the AND gate 8, the sending of pulses supplied by the clock 9 to the counter 11 which counts these pulses and transmits the digit corresponding to the multiplexer 12.
  • the remote coding signal supplied by the line 13 controls the multiplexer so that the latter write the aforementioned digit in memory 4.
  • the slot counter 10 counts the slots sent by line 7, that is to say in fact the coding digits sent; the output of this counter is sent to the multiplexer 15 and the remote coding command provided by the line 13 acts on the multiplexer 15 so that the latter modifies the address of the memory 4 according to the number of slots counted by the counter 10.
  • the invention makes it possible to record an opening code in the memory 4 either from the keyboard 1 or from the remote coding unit, from which the lines 6,7, 13 and 21.
  • the remote or local coding is each time carried out under the control of the coding unit which sends the corresponding orders.
  • a false code alarm signal is generated, when a certain number of false codes are dialed on the keyboard during a predetermined period. This is achieved in the following manner; each time the circuit limiting the number of digits entered 17 records a number of digits entered equal to the number of digits in the code, not only does it reset the counter 16 of digits entered but it controls the timing circuit 24 so as to start a time delay of 30 seconds, for example. This limiting circuit 17 also sends a pulse to the counter 25 of input codes which provides a signal to the AND logic circuit 26 when it has counted a predetermined number of entered codes.
  • one of the input ports of the AND circuit 26 can be connected to the output of the counter 25 corresponding to the most significant bit, namely 8; in this case, each time the counter 25 has eight input codes, it sends a signal to the AND circuit 26.
  • This latter AND circuit also receives the timed signal supplied by the timer 24 so that if this predetermined number of codes was carried out for the duration of the timed signal, a false code alarm signal is obtained at the output of circuit ET 26 which can then be memorized and sent to the remote coding unit.
  • This alarm is preferably carried out discreetly so that the personnel present at the remote coding unit is the only one informed of these attempts to open the door.
  • the opening signal provided by the OR circuit 20 inhibits the timed signal of the timing circuit 24; this circuit also makes it possible to carry out a reset to the device generating the false code alarm signal after the door has been opened by an authorized person.
  • the counter 25 is reset to zero by the delay circuit 24.
  • the keyboard is locked for 10 seconds then for 20 seconds following a second false code, then for 40 seconds following a third false code and so on.
  • the components of the diagram in FIG. 1 can be replaced by components performing the same function, more particularly, the keyboard 1 can be replaced by any type of device capable of generating a code (optical code reader, magnetic bar, infrared, hyper-frequency, ).
  • the memory 4 described is of the parallel input type but it is obvious that a non-random access memory can be used volatile so as to keep the code in the event of removal of the supply voltage, otherwise it would be impossible to obtain the opening. In this case it is then a memory with serial input and not parallel.
