Definitions

  • the invention relates to a circuit arrangement which is provided for electronically coded locking of locks and with one or more keys for entering the code signals and with devices for storing the code to be recognized for unlocking and for processing the signals, i.e. for comparing the decoding signals with the stored code, for deciding and for triggering the unlocking if the decoding signals match the stored code.
  • the circuit arrangement according to the invention is particularly suitable for bags, suitcases and other portable containers, but it can also be used for door locks, car locks and other types of locks.
  • Numerous locks with electronic locks are already known. Since their function depends on a secure power supply, these locks are only suitable and intended for stationary installation.
  • the object of the invention is therefore to overcome these disadvantages and to provide a circuit arrangement with electronic coding which is also suitable for suitcase locks and with which the case can be reliably locked and opened at any time.
  • mains-fed systems it should be ensured that the lock can be unlocked even after a mains failure.
  • the supply voltage is checked automatically after each closure actuation under load and / or regularly at predetermined intervals.
  • a threshold value which is 70 to 90% of the nominal voltage
  • all functions are switched off, but the memory content is retained until the voltage drops to 30 to 50% of the nominal value by pressing the button again or applying an external voltage source, the return to the normal operating state takes place.
  • a microcomputer is provided as a device for controlling and processing the signals and for controlling the voltage monitoring.
  • FIG. 1 shows in block diagram an embodiment of the circuit arrangement according to the invention.
  • Figure 2 is also a block diagram of another embodiment in which a microcomputer is used as a memory and to control the various functions.
  • the circuit arrangement according to the invention essentially consists of a control unit 1, into which the code signals are input via two keys 2, 3, an event counter 4, a shift register 5, a coding field 6, a comparator and decision circuit 7 and from units 8 and 9 for generating the unlocking or locking pulses. Furthermore, a timer 10, a signal generator 11, a power supply 12 and a voltage monitoring 13 are available. The locking mechanism of the lock, not shown, which responds to the unlocking and locking signals of the units 8 and 9, is also indicated and designated by 14.
  • the coding field 6 is a mechanical memory
  • the coding is expediently carried out with the aid of coding switches or wire jumpers which are separated for coding, or by programmable diode arrangements and changed by the user if necessary.
  • the coding field 6 is only accessible when the container is open - this is a bag or a case. Since it is a mechanical storage arrangement, it is insensitive to magnetic or electrical interference fields. If the power supply fails, the coding is also retained, but of course an unlocking pulse can only be generated if the energy source is available.
  • the power supply 12 is therefore provided with the voltage monitor 13, which triggers an unlocking pulse and, if appropriate, a signal when the voltage drops below a threshold value.
  • the decoding ie the keying in of the predetermined code to be decrypted, is carried out by the user with the aid of the two keys 2, 3, which have different values and corresponding to that Code must be operated in a specific order.
  • the code the number sequence of a date, an account number, passport number or the like can be used, for example, if one key is pressed when the number is odd and the other key is pressed when the number is even.
  • the rhythm of a particular song is also useful as a reminder if one key is assigned short pauses, the other long pauses. In general, it should also be no problem to remember the sequence of key actuation given as a code without reminder.
  • the decoding signals can be entered blindly.
  • a maximum time of e.g. 3 s must not be exceeded, because otherwise the time counter 10 reset with each keying would delete the entire previous entry.
  • the entire system is reset to the starting position by simultaneously pressing buttons 2, 3.
  • the event counter 4 is advanced by one step. After entering the number of keys specified by the coding, the event counter 4 prevents the time counter 10 from being reset again, and the comparator and decision circuit 7 is activated via the control unit 1, which switches the shift register 5 by the decoding process, that is, by pressing the key 2, 3 entered information tion compared with the bit sequence specified in the coding field 6. If there is a match, the unlocking stage 8 is activated as a function of the control unit 1, an unlocking pulse is triggered and the locking mechanism 14 is thus released. In addition, the signal generator 11 gives the user a visual or acoustic prompt to open the closure. After the time period specified by the time counter 10 has elapsed, the signal caused by the stage 11 ends and - again controlled by the control unit 1 - a locking pulse or a pulse sequence is triggered via the stage 9.
  • both the triggering of the unlocking and locking pulse can be made dependent on a repeated actuation of the key 2 or 3.
  • the system is reset to the starting position so that a new decoding process can begin.
  • only key 2 is used to enter the code signal sequence, while key 3 is used to mark the beginning and end of the signal sequences.
  • the event counter is only advanced by one step each time the marking key 3 is pressed. Otherwise, the construction and operation of the circuit is similar to that shown.
  • the number of keyings and coding options required depends primarily on the memory used for the coding field and shift register. A sufficient number of encryption options in practice can be achieved with an 8-bit memory.
  • a commercially available 9-volt battery was used for the circuit arrangement according to FIG. 1, which is provided for a suitcase or pocket lock, which guarantees an operating time of over 10,000 hours, that is approximately 1 year.
  • the power consumption of the evaluation arrangement according to the invention is extremely low because only a short pulse is required to trigger the unlocking as well as to lock.
  • the voltage monitor 13 which ensures that the container is unlocked when the voltage drops, releases the time counter 10 as soon as the voltage falls below a limit value via the control unit: 1 permanently.
  • a certain number of unlocking processes are triggered while preventing a new locking.
  • the state "closure no longer secured" is also indicated by the signal generator 11 by means of pulsed light signals or a mechanically triggered continuous signal.
  • the coding can be changed at any time individually by the user using the buttons 2, 3 after actuation of a switch (not shown).
  • all essential functions are controlled by a microcomputer 15.
  • the coding and decoding signals are preferably entered serially via one or more keys in the keypad 16. In some cases it is advantageous to provide separate keys for code entry and for auxiliary functions. With the switch 17 indicated by dashed lines in the keypad 16, certain functions can be signaled or controlled, for example the completion of the code entry, code acceptance, unlocking of the lock regardless of the time of the decoding, etc.
  • the switch 18 is arranged such that it is no longer accessible after the locking, e.g. inside a suitcase.
  • the "Test” switch position is important for learning or practicing coding and decoding, because in this switch position no locking can occur, but only correct coding is indicated with the aid of the signal transmitter 19.
  • an oscillator 20 is expediently connected externally to the microcomputer 15, with whose associated frequency divider 21 a particularly favorable working frequency for the microcomputer 15 can be set. With a view to low power consumption, the working frequency should not be higher than necessary.

  • the locking mechanism has, as an essential element, an electric servomotor 25 which moves a locking bolt (not shown) axially - depending on the direction of rotation - from one end position to the other, with the aid of the limit switches 26, for example Hall effect position switches, the respective end position is reported back to the microcomputer 15 via the line 28.
  • the control here motor control "right / left", is symbolized by 24 in FIG.
  • an additional motor current monitoring is designated, which comes into operation, for example, when the locking mechanism is "jammed” and either causes a reversal of the direction of rotation of the locking bolt or a shutdown via the microcomputer 15 and the motor controller 24 in order to overload the motor and cause it to prematurely To prevent battery consumption.

  • the battery voltage U B is measured according to the invention with the aid of the voltage monitor 30, which is likewise controlled here by the microcomputer 15, and the battery is tested.
  • the voltage is measured each time the motor 25 is started after a delay of approximately 100 ms, ie after the start-up phase of this motor has ended. If a threshold value is undershot, an optical or acoustic signal is triggered via the signal transmitter 19 and at the same time the renewed locking, but not the unlocking, is prevented.
  • the threshold is, for example, 4.8 volts.
  • the programmed code is retained until the voltage drops below approximately 2.7 volts. If the voltage of the aged battery remains above this limit, the normal function can be restored via the connections 31 after connecting an external battery, a power supply unit or the like.
