SU378840A1 - DEVICE FOR ISOLATION FROM THE RESULTS OF THE SOLUTION OF THE PRODUCING FUNCTION FOR COMBINATIONS - Google Patents

Description

The invention relates to automation and computing and can be used in control systems.

A device is known for determining function values representing an algebraic sum of combinations of one or several variables, comprising a pulse generator, delay lines, a key block, an information logger, a pulse number analyzer, a logic adder, and a switch.

However, using this device, it is impossible to determine the combinations of variables themselves in the indicated functions.

The proposed device is characterized in that the outputs of the pulse generator are connected through delay lines and a key block to the inputs of the information recorder and to the inputs of a pulse number analyzer, the outputs of which are connected through an inverse logic modulator and switch to the control input of the key block.

This allows you to extend the functionality of the device.

The drawing shows the proposed device. It contains a pulse generator / with outputs 2, an analyzer 3 of the number of pulses with inputs 4 and outputs 5, containing, for example, resistors 6, 7 and- 8, switches of specified combination indicators with contact pairs 9, 10, waiting for multivibrators

11, 12, diodes 13. The device also contains an inverse logic adder 14 modulo two, switch 75, delay lines 16, an electric switch block 77 with operating 18 and control 19 inputs and outputs 20, for example, on triodes 2 / , diodes 22, resistors 23, 24, and information recorder 25.

The device can operate in the mode of calculating the total result of the generating function (the first mode), as well as in the mode in which only the combinations combined by the specified combination of

 one /-

  ) ..))

(second mode).

When working in the first mode, the switch 15 is disconnected from the blues. 17 keys, the output of the logic adder 14. The control input 19 is provided with a "zero signal, which ensures its open state. By the command "Start-up, the generator 1 enters into operation and generates signals of the binary code with the following frequency /, and when forming 2 different code messages, it automatically turns off. Coded signals with generator 2 output / through delay lines; 16 arrive at inputs 18 open by

all channels of the block of 17 keys and through it

the outputs 20 to the registering device 25, where the code packets comprising all combinations of the result of the calculations are recorded.

When pai6oTe is in the second mode, the switch 15 connects the output of the logic adder 14 to the control input of the key block 17, and contacts 9, 10 of the switches of a given combination indicator close certain circuits in the analyzer 3. In the drawing, the first top contacts 9, 10 of the analyzer switches 3 turn on if It is necessary to calculate all combinations of variables one by one.

(+ +. +) A

at THIS, all other pins 9, 10 of the analyzer 3 dispensers are turned off.

The second contacts from the top of the list of the switches of the analyzer 3 are turned on, if it is necessary to calculate all combinations of variables by two

(Х.Х., + Х, Хз +,... + Хп-1Х „), etc.

In the second mode of operation, the device calculates all the combinations of variables by two. To do this, in the analyzer 3, I and the JO contacts of the second one are closed.

The command "Start code signals from outputs 2 of generator 1 at 1 are fed in two directions: through delay lines J6 to the working inputs 18 of key block 17 and directly to inputs 4 of analyzer 3. If the code message contains two current pulses in any of the circuits these pulses, passage through resistors 6 and diodes 13, are then summed algebraically and in the form of a double current pulse through closed contacts 9 of the switch (second from the top) and resistor 7 (the second from the top) are fed to the input of the multi-set device: 11. Resistor 7 such that the multivibrator 11 n A double current pulse triggers and generates a “single signal at the input of the logic adder 14. At the same time, the double current pulse signal passes through the closed contacts 9 of the switch (second from the top), the resistor 8 and the closed contacts 10 (second from the top) of the switch to the input of the multivibrator 12. At this is the resistance value of the resistor 8 (second from the top), such that the multivibrator 12 does not work, but will only work on the algebraic sum of a signal containing three or more pulses.

Thus, according to the algebraic sum of two pulses, the multivibrator 12 does not work, and at its output a “zero signal is formed, and according to the algebraic sum of three or more pulses, the multivibrator 12 operates and at its output a“ single signal is formed. According to the signal corresponding to one pulse in the code, the AND multivibrator does not work, and at its output a "zero signal is formed.

At the input of the logic adder - 14, depending on the number of pulses in the code, the following signals are sent:

one impulse in the code parcel - signals with multivibrator L and 12 "zero;

two pulses in the code message - the signal from the multivibrator 11 is “single, and from the multivibr-ator 12” is zero;

three or more pulses in the code are signals from multivibrators // and 12 "single ones. Thus, at the output of the logic adder 14 modulo two, a vue signal is generated only if there are two pulses in the code message. If there is one, three, or more pulses at the output of the logic circuit in the code parcel

14, a "single signal" is generated. For the "zero signal, the key block 17 opens and passes the code signal, which is delayed by the time of the transition process in apalizer 3 and logic adder 14,

only two impulses. On the "single signal, the OK key of the keys 17 is closed and does not transmit code signals containing one, three, or more pulses. All code signals containing two pulses pass

through the key block 17 to the recorder 26, and the multivibrators 11, 12 are reset.

When installing the cell analyzer 3 (I 10 coy-contacts) on any other number of pulses in the code send, the device circuit works in a similar way.
