Description

one

The invention relates to the field of automation and computer technology and can be used in devices for processing discrete information.

A voting device is known, containing registers, but coupled with comparison circuits, an output unit connected to one ii3 of registers, triggers, circuits, assemblies and assembly circuits.

The purpose of the invention is to expand the functionality of the device by using the results of CpB | Neni numbers to reject numbers that have a significant deviation from a certain average value of the number of numbers that are not analyzed and replace the rejected number by a subsequent number from this number, i.e., accept. Decisions on / r numbers from m numbers to output numbers from the device.

This is achieved by integrating an IMPulse dispenser connected through an assembly circuit to reset inputs of triggers, whose outputs through the first group of matching circuits are connected to the inputs of registers, the outputs of comparison circuits through the second group of matching circuits, the second inputs connected to the distributor pulses, and the outputs through a multi-input circuit coincidence - to the input of the output unit and the input of the distributor "pulses, and the circuit assembly

Dineny with the inputs of the corresponding triggers and registers.

The drawing shows a block diagram of the device.

It contains triggers I, 2, and 3, schemes 4-9 matches, distributor 10 pulses, registers Y, 12 and 13 numbers, comparison circuits 14, diagram 15 matches, information output block 16, eborki circuits.

The principle of the voting device is that the first three of the four numbers intended for analysis are memorized, and their ratios are determined by voting these numbers. If the numbers 1a are equal to each other with some given accuracy, then the operation of the voting device ends. It is decided that all four cells are equal and one of the numbers is derived from the device. When only two of the first three are equal, the number that is different from the other two is replaced by the fourth and the vote is repeated. If, as a result of the voting, three identical 1x numbers are not found, then the cycle of operation of the voting device for these four numbers is ignored. In this case, it is decided that the numbers differ from each other more than by the value specified by the 1st voting accuracy and the number is not output from the device.

The voting device operates as follows.

In the initial state, triggers 1, 2, and 3 have a ban potential on circuits 4, 5, and 6. Schemes 7, 8, and 9 of coincidence are closed by a prohibition potential from the distributor of 10 pulses. Registers of 11, 12, and 13 numbers are cleared.

When the device is operating, its inputs 18, 19, and 20 are supplied with tightly connected sequences of pulses in time.

The pulses fed to input 76 are codes of numbers that are processed in this device. In the simplest case, this is a single code of numbers in the form of a pulse stuffing. These bursts of pulses affect circuits 4, 5, and 6. However, the passage of bursts of pulses to registers L, 12, and 13 depends on the state in which the triggers Ij 2 and 3 are controlled by the pulses coming in from Hia inputs 19 and 20.

The pulses that are knocked out at input 19 affect the triggers 1, 2 and 3, driving them to their original state.

The pulses arriving at input 20 are converted in the pulse distributor W into three sequences of pulses separated in time and tightly coupled in phase.

The first sequence of pulses formed in the distributor (as well as the next two, similar to the first one), is formed by separating each fourth pulse with some delay from the sequence of pulses entering the input 20. The phases of the three sequences of pulses are shifted one relative to the other by the value of the period of the pulses arriving at the input 20. These sequences of pulses control the operation of the D 2 and 5 flip-flops and serve to issue commands to enter the number codes in registers 11, 12 and 13.

The input of the pulse bursts into the registers of the proceeds is as follows.

After the next pulse arriving at input 19, the triggers 1, 2, 3 are reset. Then in time there follows a pulse from the distributor, which sets trigger 1 to a position different from the initial one. The prohibition potential of match 4 is removed. A burst of pulses corresponding to the first number is entered in register 11.

The next impulse arriving at input 19 (the second impulse) returns the trigger 1 to the initial state and thereby supplies the inhibition potential for the coincidence circuit 4.

The next moment a pulse is passed from the distributor, acting on trigger 2. The trigger changes its state to the opposite of the initial one, and the packet of pulses corresponding to the second number is entered into register 12. Similarly, the burst of impulses corresponding to the third number is entered into register 13.

Codes of numbers stored in registers 11, 12,

13 are compared with each other in comparison circuits 14.

When the codes are entered into the registers, the distributor generates a resolution signal for voting numbers. Such a signal is the removal of the inhibit potential from the 7, 8, and 9 cobpa.day schemes. The inhibitory potential is removed by the fourth pulse, which comes in on input 19 from the start of the cycle.

When voting, various situations of equality or inequality of numbers may arise. Here an approximate equality of numbers can take place, i.e. when the comparison is conducted with a given accuracy.

Consider the operation of the device in some typical situations. Let 1CODES of the numbers AI, A2 and A be entered into the registers, one of which differs from the other two, for example L, L2 Lz.

In this case, in the comparison circuit 14 turned on at the outputs of the registers 12 and 13, a coincidence signal is formed. The coincidence signal through circuit 9 to the input of the trigger /, overturns it to a state other than its equivalent, and clears the register //. There are no matching signals at the outputs of circuits 7 and 8, since and. The next impulse arriving at input 20 recovers the inhibit potential in circuits 7, 8, and 9. The next burst, corresponding to the number A, is entered into the register //. When the input of the bundle is completed, the prohibition potential is removed from schemes 7, 9 and 9. The numbers AZ, Lz and A. are voted on.

If now, for example, condition L4 2 Lz is fulfilled, then at the output of all circuits 7, 8, 9, 15 coincidence signals appear.

The signals from the outputs of the circuits 7, 8, 9 affect the triggers 1, 2, 3 n and the registers //, 12, 13 in the same way as described. As a result, the I, 2, 3 triggers are in a position different from the original, and the registers 11, 12, 13 are cleared. However, registers are cleared only.

after some time sufficient to output the code of the number from register 11 (the delay is entered in the registers).

The output of a number code from register 11 is carried out through a block of K 16 output, information

a match signal taken from the match circuit 15.
