Definitions

  • the invention relates to a code input device for a predetermined set of code characters, for example for an access or authorization control device, with an actuating device, an electronic processing unit and a display device.
  • control devices In order to prevent unauthorized persons from gaining access to secure rooms or from using devices and devices that are reserved only for authorized users, control devices are known to be used, in which the user must enter a coded proof of authorization. An electronic processing unit checks the code and only releases it if the specified code characters are entered in the correct order. Keyboards for typing code characters are very common. Although they have proven themselves very well, it cannot be ruled out that the entered code characters will be misused using fingerprints and that the authorization identification will be reconstructed in this way by an unauthorized person.
  • the invention has for its object to provide a code input device of the type mentioned, which prevents the determination of the code by preparation of the actuating device and / or by observing the process by an unauthorized person is possible.
  • This object is achieved in that the code characters are reproduced in a user-independent, predetermined sequence under the control of the processing unit on the display device, and in that when a relevant code element is reproduced, the user confirms via the actuating device.
  • a basic idea of the invention is therefore that a "search run" for the individual code characters, which cannot be traced or reconstructed from the outside, is carried out, which can only be followed by the authorized person on the display. Since the display is volatile, ie leaves no traces, subsequent reconstruction of the characters themselves and their order is impossible. For the same reason, an assignment to the character concerned is excluded if the character confirmation is carried out by the user. In other words, the actuating device does not assume an evaluable position if it is used to enter a correct code element, so that manipulation of the Actuator or a preparation is futile.
  • the individual code elements it is possible for the individual code elements to be changed automatically after a predetermined time. It is particularly expedient, however, that an operating element for switching on is available. The user can therefore determine the time himself, so that the risk of input errors is reduced.
  • the user-controlled indexing contributes to the security being increased still further, because the operation of the input device is even more randomly dependent due to the lack of fixed cycle times.
  • a preferred development of the invention is that a random generator or the like. is present, which defines a new code character sequence each time the code input device is started up.
  • a structurally simple and easy-to-use actuating device consists of the fact that it consists of a switch having at least three switching states, one switching state being the "ready" position and in the other two switching states the code character advancement or code character confirmation taking place.
  • the switch is preferably designed as a rocker switch or as a rotary knob with a switching lug and two switching contacts interacting with it.
  • a preferred development of the actuating device is that it is designed as a rotary knob with a predetermined number of angle-dependent switching points. Each switching point can be assigned a value within a code string. Therefore, if the rotary knob is advanced, the code elements with the next following significance are shown on the display device.
  • Another actuating device consists in the fact that a slide potentiometer is present, the output voltage of which determines the switching point.
  • the code input device acc. 1 and 2 are used to control an electric door lock for a security container, for example a safe. It comprises a housing 2 for a display device 4 and the electromechanical and electronic components of an actuating device 6, of which a rotary knob 5 with a Wave 7 is shown.
  • the display device 4 in the example shown consists of a single-digit LED numerical display, which is surrounded by a three-sided screen 3 as a screen.
  • the display device 4 and the electromechanical part 8 of the actuating device 6 interact with an electronic processing unit (not shown), which can also be integrated in the housing 2.
  • the housing 2 is mounted on a carrier plate 1 on the container side. The housing 2 is secured so that the electronic and electromechanical elements are inaccessible.
  • the function of the code input device is explained below on the basis of an authorization identification consisting of four code characters.
  • the device is ready for operation at a first angular position of the rotary knob 5, which is signaled by a corresponding symbol on the display device 4.
  • a random generator contained in the processing unit determines the sequence of all possible code characters and a first character (number 8 in FIG. 2) is reproduced. By further turning the rotary knob 5, the remaining code characters appear one after the other in the random order. As soon as the first code character of the relevant authorization identification is displayed, the operator confirms by pressing the rotary knob 5 and thereby triggering a corresponding switching operation.
  • the display and dialing process is then repeated for the three remaining digits of the authorization identification. With each pass, the code character order redefined.
  • FIG. 3 shows a rotary potentiometer as an example for the electromechanical part 7 of the actuating device 6 in an axial plan view.
  • the rotary potentiometer is connected to the rotary knob 5 via a shaft 7 '.
  • the switching operations described above are carried out by moving a tap 9 via a resistance track 10.
  • a signal transmitter 12 connected to the shaft 7 ′′ in a rotationally fixed manner interacts with one or more stationary light barriers 11.
  • the shaft 7 '' ' is provided with a radial switching lug 13 with which a first switch 14 is actuated in the case of a left-hand deflection and a second switch 15 in the case of a right-hand deflection.
  • One switch serves to advance the code elements and the other switch to confirm a correct code element, as has been described in the context of FIGS. 1 and 2.
  • FIG. 6 An example of a code input device is shown in FIG. 6, in which the actuating device 16 comprises three key switches 17, 18, 19 with two switching states. In the basic state, the display device 4 is deactivated, i.e. dark. A typical code entry for the exemplary line code "4711" proceeds as follows.
  • the key switch 19 is pressed, which has the result of the activation of the code input device and the random generator outputs the number "7" as the starting value.
  • the operator can now either count down the number "4" by pressing the button 17 three times for display bring and confirm with the key switch 19.
  • the random generator is started again and the next start value, for example the code number "9", is displayed.
  • the appropriate code number "7" can again be displayed by counting up and down and confirmed with the key switch 19. This process is repeated for all 4 code characters.
  • the example for a further input device according to FIG. 7 comprises, in addition to three key switches 17 ', 18' and 19 ', which have the same functions as in the example according to FIG. 6, a multi-digit and multi-line display device 4'. Two lines with 13 digits each are shown here as examples. This is an LED sign display for the display of letters, numbers and symbols, which is covered by a privacy screen film and is protected against lateral view.
  • the display is deactivated in the basic state. If the key switch 19 'is pressed, an operating instruction or information for the user appears, here the instruction "enter code”. A first digit generated by the random number generator is also reproduced. By pressing the key switch 17 'or 18', the operator can enter the appropriate digit of his code word by counting up or down and confirm it with the key switch 19 '. If this process is carried out correctly, the Number deleted from the display and indicated by a symbol, here the symbol "*". In this way, the operator has control over which part of his code word is currently being checked. In FIG. 7, two symbols "*" indicate that two code digits have already been entered correctly and that the third digit is currently waiting to be checked.
  • any other instructions can of course be given to the operator, such as "repeat entry” or the like.
  • the display device 4 ' can be used for other displays, for example for displaying the real time or the last use of the code input device, etc.
