Description

The invention relates to code locks .., A code lock is known, comprising an execution unit connected to the counter of the number of characters of the code connected to the output of the AND element, code set block connected to the code set counter, and code setting block 1. The disadvantage of the known code lock is low secrecy. The purpose of the invention is to increase secrecy. The goal is achieved by the fact that a code lock containing an executive unit connected to the counter of the number of characters of the code connected to the output of the element -I, the code-dialing unit connected to the code-dial counter and the code setting unit contains the code-fixing unit, the decoder , selector, distributor, the code set block is additionally connected to the distributor connected to the counter of the number of characters of the code, the first input of the execution unit, the first group of inputs of the selector, the second group of inputs of which It is connected to the outputs of the code setting unit, and the output is connected to the input of the element I, to the second input of which the code fixing unit is connected, connected to the distributor and code set counter, connected via a decoder to the code setting unit, and the output of the code character count counter is connected to the second input executive unit. In addition, the distributor contains a counter, a decoder, the elements AND, OR, and the counter is connected to the decoder and the element AND connected to the element OR. FIG. 1 shows a functional diagram of the device; in fig. 2 is a code setting unit, in FIG. 3 - distributor. The device consists of an executive unit 1, a counter 2, the number of characters of a code, an element I 3, a block 4 of a set of code, a counter 5 of a set of code, a block 6 of setting a code, a block 7 of fixing the code of a decoder 8, a selector 9, a distributor 10 which consists of a counter 11 decoder 12, the element And 13 and the element OR 14. The device operates as follows. When the code is typed in block 4, the signals from its outputs go to counter 5 and valve 10. At the output of the distributor, depending on the character typed in block 4, the enabling signals appear that go to the inputs of the selector 9, the counter 2 of the number of characters of the code and the execution unit 1, and at the output of counter 5, signals appear that are processed by the decoder 8 and are fed to the input of unit 6, the switches of which are set in advance to the corresponding position. If the sign of the code is typed correctly, the signal from the output of the decoder 8 passes through block 6 of setting the code to the second group of inputs of the selector 9. When the information at the inputs of the selector 9 coincides, a signal passing through the AND element appears at its output, to the input of which the signal from block 7 of fixation of the code, which is turned on after dialing each character of the code. At the output of AND 3, a signal appears that changes the state of the code character count counter by one. After a set of necessary characters and fixing their number in the counter 2 of the number of characters of the code, a permit signal appears at its output, arriving at the input of the execution unit 1, the second input of which receives a signal from the distributor 10. When these signals coincide, the execution unit is triggered.
