Description

The invention relates to digital computing and can be used to optimize control processes in programming techniques.

The purpose of the invention is to expand the functionality by simulating the search for the desired code combination and determining the search time.

The drawing shows a diagram of the device.

The device contains a trigger 1, a counter 2 codes monitored in implementation, a counter 3 of the total number of monitored codes, a group of counters 4 code combinations, a sensor 5 random numbers, a register 6 of memory, a switch 7, a generator 8 of polling pulses, element 9, a decoder 10 , element OR 11, setup input 12 and device launch input 13.

The device works as follows.

Before the operation of the device, through its installation input 12, the installation inputs of the 3 and 4-pulse counters are given a signal that obliquely connect these counters. Then, a signal is applied through the input 13 of the device, which is fed to the installation input of the pulse counter 2 and to the trigger input 1. In this case, the pulse counter 2 is zeroed and the trigger 1 goes to state 1, allowing signals to pass through the AND 9 element.

The pulse generator 8 generates a sequence of pulses corresponding to the control period. These pulses through the element 9 come to the control input of the switch 7.

The random number sensor 5 generates random codes that are fed to the input of register 6, which is intended for the operational storage of the next random code. From the output of register 6, a random code is fed to the information inputs of switch 7. The control signals to the control input of switch 7,

Os

allow codes to pass through switch 7 (with FO frequency). The number of pulses received at the control input of the switch 7, and hence the number of codes received at the output of the switch 7, is counted by counters 2 and 3. Thus, the information flow (information sensor) is simulated.

From the output of the switch 7, a random code is fed to the input of the decoder 10, which, based on the analysis of the received code, generates a control signal at one of its outputs. The control signal at the outputs of the decoder 10 may or may not occur. The latter case is most characteristic, since of the entire set of possible codes, only a small number (subset) of codes are of interest,

The quantities of control, their signals at the outputs of the decoder 10, are counted by counters of 4 pulses. When a random code appears from a certain subset M, the control signal from the corresponding output of the decoder 10 through the OR 11 element is also fed to the input of the trigger 1, which then goes to the state O, prohibiting the passage of signals through the AND 9 element.

The operator records the readings of the counters 2 and 3 pulses (to determine the search time) and sends a control signal to the device start input to continue the search. In this case, the counter of 2 pulses is reset, and the trigger 1 again enters state 1, allowing the signals to pass through AND 9.
