SU1309057A1 - Device for selecting features in pattern recognition - Google Patents

Abstract

The invention relates to the field of automation and computer technology and can be used to select features for pattern recognition. The proposed device allows the selection of pulses from depth mark sensors in determining the depth and thickness of mineral deposits during geophysical surveys of wells. The aim of the invention is to simplify the device. This goal is achieved by introducing a second trigger, a second and a third OR elements into the device, and the trigger is controlled both during the lifting of the downhole tool and during the descent. The signals of this trigger select input pulses from interference to the output of the device through the OR element. 3 il. co

Description

The invention relates to automation and computing, in particular to devices for selecting signs in pattern recognition, and can be used for geophysical well surveys.

The purpose of the invention is device shedding.

FIG. 1 shows a functional diagram of the proposed device; in fig. 2 and 3 - time diagrams of his work.

The device contains the first 1, second 2, third 3, fourth 4, fifth 5, sixth 6, seventh 7 and eighth 8 elements And, the first 9 and second 10 amplifiers, the first 11, double 14 trigger, changes its state to the opposite. As a result, the subsequent pulses from the output of the second amplifier 10 through the element And 8 do not pass, so 5 as at its second input there is no allowing, its signal. At the same time, the pulses coming from the output 20 of the angular velocity sensor (Fig. 26) are fed through the first amplifier 9 and the prescaler 19 to the first inputs of the first 1 and second 0 2 elements AND, and depending on whether the enabling signal is received from The outputs of the first 21 or second 22 displacement sensors to the second inputs of the first 1 and second 2 elements AND go to the subtraction 12 and the third 13 elements OR, the first thawing or summing input of the counter, 14 and the second 15 triggers, the first 16 and the second reversible and having a swarm of 17 defifters, with a pair of .18 and a delimiter equal to N.

The second trigger 15 is in the bins (sensors not shown) of the initial state and the enable level.

The device works as follows. There is no output. When the counting is reached, the signals arriving at the input 23 of the ticks 18 of a state equal to n, of the second device are shown in FIG. 2a, where the indicated 25 encoder 17 produces a pulse, interference pulses and main pulses are delivered. The second input element AND 4 and

These signals come from the sensor mark the first input element And 6. This pulse is on

depths. The latter is the mag- netic output of the latter does not pass, since the electric head with amplification chains and I 4 is closed by a signal from the output of the world station 21, near which the steel passes — the first interchip sensor, and element 6

closed by the zero signal from the output of the second trigger 15. When the state of the counter 18 reaches the state .Vn, the first decoder 16 generates a pulse (Fig. 2e) arriving at the first input of the element And 5 and for recognizing minerals at the second input of the element And 3. This im- (for example, oil and gas), it is necessary that the railway passes only at the output of the element

The impulse from the output of the element 3 comes through the second element of this target, an angular velocity sensor 40 OR 12 is applied to the setup input of the second lifting trigginess, the frequency of which is 15 15. The latter switches and delivers

The angular velocity trick is fed to the first 9 amplifier. After the pulses are formed by the first 9 amplifier and the frequency is divided by the frequency divider 19, they have the form shown in FIG. 26. In the initial position, the first 14 trigger is in the single state and the permissive level from its output is fed to the second input of the And element 8. The first pulse arriving at the input of the device 23 through the second amplifier 10, the first input of the And 8 element, the fourth input of the first 11 of the element OR is fed to the input of the installation of the zero of the counter 18 and to the input of a perpulse arriving at the input 23 of the device through the second amplifier 10 and through the first input of the seventh element And 7, passes to
