ELECTRONIC CODE LOCK Russian patent published in 2002 - IPC

FIELD: electronic engineering. SUBSTANCE: the electronic code lock has a code reception unit, comparison unit, actuating code, controlled code converter, the first, second and third counters, display unit, storage and an input line. The input line of the electronic code lock is connected to the first group of inputs of the comparison unit, whose first output is connected to the input of the actuating unit. The second output of the comparison unit is connected to the input of the first counter of the number of attempts of code setting, whose output is connected to the input of the first counter of the number of attempts of code setting, whose output is connected to the input of the second counter, whose group of outputs is connected to the first group of inputs of the display unit and to the group of inputs of the storage, whose group of outputs is connected to the first group of inputs of the controlled code converter. The group of outputs of the code converter is connected to the second group of inputs of the comparison unit, the output of the second counter is connected to the input of the third counter, whose group of outputs is connected to the second group of inputs of the display unit and to the second group of inputs of the code converter. EFFECT: reduced probability of lock opening by code setting. 1 dwg
