SU24539A1 - Installation for psychotechnical testing of drivers - Google Patents

Description

One of the main professional qualities of a transport psychotechnician to a chauffeur is the eye. An eye test, when the driver all the time deals with the assessment of the rapidly changing space between any objects where he directs his car, should not be of a static nature. The proposed installation has in mind the dynamics in the testing of the eye gauge and the approach of the test to the actual working environment of the driver.

The installation for psychotechnical testing of a chauffeur shown in the schematic drawing consists of two rows of AB and CD light bulbs, encased in long and narrow boxes with frosted glass on the front walls facing the subject. A longer box at a height of one meter from the floor with AB bulbs hangs on the wall, occupying its entire length, and is located at a distance of 5-7 m from the subject; another, smaller, with CD bulbs, equal to the width of the car (about IVs) stands on the floor in wooden racks at a height of D m and is placed in front of the subject at a distance of one m. The lamps in the boxes are arranged so often that when ignited, they are obtained through dull glass solid light stripes. The AB lamps, according to the space they occupy, are divided into several combinations, the number of which should not be less than ten, and some of these combinations should be along their length

more than yes. CD lamps, others less than it. These combinations can be extinguished with the help of the devices described below, forming dark breaks in the bright band of the AV strip and ignite again. These dark breakthroughs appear alternately in the light band, one after the other, then in the middle of the strip, then at its very edges, then, overlapping each other, occupy intermediate positions.

The subject, sitting in front of the CD light bulbs, should quickly evaluate each dark slit in the bright ribbon of AB light bulbs with respect to the light CD bar. If the breakout is smaller than the CD band, he should press the F tone with his right hand, letting it know that the CD light band, which is equal to the width of the car, does not fit in the dark breakout of the AB band, i.e. the car will not pass without hitting anything in the way. If the dark break in the light band AB is larger than the CD band, then the subject should sit quietly, do nothing with the dial tone F.

Psychotechnical testing and installation work is as follows. The hourly gramophone mechanism rotates the drum with electrical contacts located on it, due to which, when they come off from the contact fingers p, p, p, ... p, this or that number of lamps from the light band AB is turned off, thus forming the mentioned higher dark breakouts. The drum s, rotating uniformly on its axis, gives exactly that range

dark breakthroughs, in / 4 large, then smaller light-r PLBLS -CD, which successively appear one after another before the type of question and to which he must react in one way or another. The rotational speed of the drum is regulated by a brake, which is present at the ka2 ' gramophone mechanism.

Before the extinction of a combination of st lamps, i.e. when these lamps are still hot, the electromagnet f is working, attracting one end of the lever b to itself. With the breaking of the contact on the drum c, due to which the st lamps, go out, the electromagnet circuit is also broken. With this discontinuity, the end of the lever b, attracted earlier by an electromagnet, is released and right there, thanks to a spring, the other end of this lever presses the contacts c / to each other, thus connecting a new line with the battery g to the electromagnetic marker e, which serves to account for the reaction of the test. If the driver makes a mistake on this combination of extinguished lamps, i.e. presses the F signal, letting you know that the CD's light strip will not pass into the dark AB lamps breakthrough, then it will close this new line and the counter will mark one division with its arrow on the dial. Thus, whenever a dark AB breakout is larger than the CD's light band, each test subject’s error is noted by the snetchik. When the drum moves further, the contact gap on the drum is restored, all AB lamps are lit again, and the electromagnet attracting measles (end of lever B) breaks the contacts d and the whole system is ready again for action.

In another case, when the dark breakthrough TP is less than the light CD band, the same thing repeats as in the first case, only fewer lamps go out and electromagnet 1 turns off, the contacts K are connected. If the driver thinks that the light CD band does not go to the dark breakthrough of TP and it will give a signal, then the counter o, just as in the first case the counter e, will move its arrow by one division, which will show the correct reaction of the subject. If the driver makes a mistake and does not give a signal, then on the counter, o, knowing in advance how much the arrow should show when the movements are correct, should be shown by the arrow, they do not count one division.

Thus, by the number of divisions on the counter e and the lack of divisions

on the counter you can judge the error of the test.

The size of the contacts and their location on the drum from one another is reduced. With each new appearance of a dark breakthrough in the line of AB lamps, in order, therefore, to gradually create for the examinee more and more severe conditions of testing.

To stop the installation when all testing is completed, install an automatic switch, which will break the electrical network by contact q located on the dial of the electromagnetic counter-meter h, and its arrow, which goes to d, thanks to a separate contact on the drum c, when all dark breaks in line AB lamps passed.

The proposed installation can be a little complicated and, as a result, besides the eyeglass, it is possible to examine other professional qualities of the chauffeur and bring the test even closer to the actual working environment of the chauffeur. Adding to this is that the crate with the CD lamps rests on the floor on the same pillar, which, together with the crate, rotates near its axis. The turns of the box with the CO lamps are made by car steering through a bicycle chain and two bicycle gears attached at the bottom of the steering column and at the front of the box. Gears must be designed so that the steering and caster turns correspond to the actual interaction between the steering wheel and the vehicle. The subject, sitting at the steering wheel in front of the crate with CD lamps, should respond to dark breaks in the line of AB lamps not only with the dial tone F, but also with the steering wheel, sent them a bright line of CD lamps to the dark breakthrough. The line of lamps L5 should represent a semicircle. Taking into account the correctness of the turns of the line of CD lamps for dark breakthroughs is produced by an electromagnetic counter. To do this, a metal arrow is attached to the rotating rack of CD lamps perpendicular to it, the end of which slides in a circle consisting of a row of copper contacts of contacts made by an insulation in 1 sls.

The circle, the arrow, and the counter are included in a separate electrical network, and the arrow on the medical plates is marked by a counter, each plate marks one division of the counter. Zk.

the sequence of passing dark breakthroughs and the position of the arrow on the numbers of the counter with correct steering turns, you can always calculate the errors of the test person in centimeters without stopping the test at each breakthrough, but only by recording the counter readings before the correct numbers in advance. After each meter reading, it is necessary before the appearance of a new dark breakthrough to transfer the meter arrow to the zero position.

The installation can be supplemented by the fact that, in a bright band, AB can appear at the same time, if the length or width of the room allows, not one dark breakthrough, as described earlier, but two or three, one of which should be longer CD's light band, and the other two are smaller.

The test subject should drive a light CD strip against a dark break in band A 5, which is more than others, indicating that a car replaced in the installation with a light CD band can pass only into this break.

With this addition, a new psychotechnical function is introduced into the test, a movement with a choice that brings the test closer to the actual work of the driver, who often has to deal with the choice of free passage among other dangerous places during the ride.

The subject matter of the invention.

The installation for psychotechnical testing of chauffeurs consisting of a seat with control levers and recording instruments, characterized in that two rows of different lengths of AB and CD electric lamps, covered with frosted glass and giving a hr of continuous light strip, are used for determining the eye and attention; than in the first row there is a clockwork recording mechanism, which causes the light bulbs to fade to produce dark breaks of various lengths and positions.
