ELECTRONIC CODE LOCK Russian patent published in 2002 - IPC

FIELD: equipment for protection of various objectives against access of strangers. SUBSTANCE: the electronic code lock has an input line, the first code receiving unit, the first comparison unit, counter of the number of attempts of code selection, the second code receiving unit, the second comparison unit, the first code converter, the second code converter, storage unit, actuator unit. The code receiving unit, connected to the input line, with a group of outputs is connected to the first group of inputs of the comparison unit, whose first output is connected to the input of the counter of the number of attempts of code selection. The code receiving unit connected to the input line, with a group of outputs is connected to the first group of inputs of the comparison unit, whose second group of inputs is connected to the group of inputs of the code converter and the group of outputs of the code converter, whose first group of inputs is connected to the group of outputs of the counter of the number of attempts of code selection, and the second group of inputs - to the group of outputs of the storage unit. The output of the comparison unit is connected to the input of the code receiving unit, the second group of the comparison unit is connected to the group of outputs of the code converter, and its second output - to the input of the actuator unit. EFFECT: reduced probability of opening of the code lock from the first attempt and enhanced maximum number of probable attempts of code selection for lock opening. 2 dwg
