Description

The invention relates to ergonomics, in particular to a man-machine system, and can be used in devices for obtaining ergonomic data from control panels for controlling technical objects.

The purpose of the invention is to improve the accuracy of ergonomic estimates of control panels.

As one of the ergonomic estimates, the time taken by the operator for controls on the test control panel, stand, stand, etc. is taken.

FIG. 1 is a block diagram of the device; in fig. 2 is a block diagram of a count of transitions.

The device of FIG. 1 contains sensors 1, -1 c, selectors, blocks for measuring the duration of intervals, drivers, single pulses, first counters 5i, -5, pulses (counters of the number of hits), counter 6 of the number of transitions, remote control 7 of the operator, block 8 of registration, element 9 OR , trigger 10, the first element 1I And, the second counter 12 pulses (time counter), the second element) -v And, the third counters (-, it puZsov, the first blocks dividing the third elements And, the fourth counters 1 7 71-, pulses , second blocks, division.

The counter 6 of the number of transitions (Fig. 2) contains (for) the first transition counters, the second transition counters, the second IL-2P-21Z IL, the fifth pulse counters.,

Each first counter of transitions (Fig. 2) consists of a second trigger 23, a fourth element 24 AND, a fifth element 25 AND, a third element 26 OR. Every second counter of transitions (Fig. 2) consists of the third trigger 27, the sixth element 28 AND, the fourth element 29 OR.

 The device works as follows.

The operator installs sensors 1 (photocells, capacitive, inductive, etc.) separately FOR comfort and uncomfortable zones directly on the test remote,

Using the Reset button (not shown), the operator erases the information in the counters, and also sets

752

trigger 10 to the cool state. The device is ready for operation.

The operator in accordance with the examination program begins to perform

operations on the control panel under test.

Suppose an operator performs operations related to its passage from one zone to another, for example, from

first to second. In this case, when the operator contacts the first zone, sensor C of the first zone is triggered. From its output, the signal through the first selector 2 enters simultaneously to

the input of the interval measurement unit 3, which fixes the time of the operator in the first zone, and 4 single pulses to the input of the corresponding generator. From the output of the first single pulse generator, a pulse arrives simultaneously at the input of the counter 5v, recording a unit in it, at the input of the counter 6 the number of transitions and through the element OR 9 to the input of the trigger 10, translating it into a single state. Thus, the first input of the MeHTst I 11 enters the trigger output of 10 units.

From the output of the operator’s console 7, from the generator of time stamps (not shown), the pulses arrive through the open element € 11 and 11 to the information input of the counter 12, being recorded in it.

The unit, coming to the input of the counter 6, the number of transitions, simultaneously arrives at the information inputs of the counters 19 and 20 and the clock inputs of the counters 19 and 20 ,, transitions

Fig „2).

In the transition counter 19, the pulse arrives simultaneously at the first input of the element 24, from the output of which the pulse is not given, since at the second

there is no unit loss of its output due to the fact that the trigger is triggered from the trailing edge of the pulse arriving at its input and the S input of the trigger 23, transferring the last one to the falling edge of the pulse in one state, 1 from its output is fed to the second inputs: Both 24 and 25.

In the counter 20 of the transitions, the pulse arrives at the S input of the trigger 23 and transfers it to the one state, 1 from the output of which is fed to the second input of the And element 28.

In the transition counters 19 a and 20 c, a pulse is applied to the first inputs of the And 25 and 28 elements, respectively.

The operator then turns to the second zone. Sensor 1 is triggered, from its output the signal goes through the selector simultaneously to the input of block B of the interval duration, which records the time that the operator spends in this zone, and to the input of the generator of single pulses, from the output of the last pulse simultaneously enters the input of counter 5, recording there is a unit in it, to the input of the counter 6 the number of transitions and through the element OR 9 - to the reading input of the counter 12, in parallel, reading the information recorded in it to the second inputs of the elements And 13 and 16. (

When enrolling at the input of the counter 6, the number of transitions is fed to the information inputs of the counters 19 and 262 at the same time, and those of the counters 191 and 19z of the transitions (Fig. 2).

In the counter of 19 tons of transitions, the pulse arrives simultaneously on the first input of the element I 24, from whose output nothing is fed, and the S input of the trigger 23, the last transfer by the falling edge of the pulse into a single state.

In the counter 20 transitions, a pulse arrives at the S input of the trigger 27 and converts it to the one state, the unit from the output of which is fed to the second input of the And element 28.

In counters 19 and 19z of transitions, a pulse arrives at the first inputs of elements 25 and 28, respectively. Since the second input of element 25 of counter 19 is supplied with a single signal-potential from the output of flip-flop 23, the pulse that came to the clock input of this transition counter is the open element AND 25 enters simultaneously through the OR element 26 to the R-input of the trigger 23, its transfer to the zero state, to the input of the counter 192 transitions, in which it passes through the OR element 26 to the R-input of the trigger 23 and resets it to the zero state , and through the element OR 21, at the same time but at the input of the counter 22, writing down the unit in it and at the inputs of the elements 13 I.

Through the open elements 13 and the information parallel to the output of the counter 12 is recorded in the counter 14. In the next operations involving the transition of the operator from one zone to another, the search time for the elements is recorded by the counters 14 when moving from the first zone to the second and vice versa

 during the transition from the first zone to the third and vice versa, the counters 14h when moving from the second zone to the third and vice versa.

If the operator performs the operation

in the same zone, for example, after the operation is performed in the second zone, it reverts to the second zone, then from the sensor output I, the signal goes through the selector 2 to the inputs of the interval duration measurement unit 3, which records the operator’s time in this zone, and shaper 4 single pulses, from the output of which the unit arrives simultaneously at the input of the counter 5 2, recording the second unit in it, at the input of the counter 6 the number of transitions and through the element OR 9 - at the reading input of the counter 12, reading

parallel recorded information on the inputs of the elements And 13 and 16.

The impulse received at the input of the counter 6 of the number of calls is simultaneously applied to the information inputs of the counters 19.2 and 202, those inputs of the counters 19 and 19z transitions.

In the counter 192. transitions, the unit enters simultaneously through the input of the element AND 24, to another input of which the unit potential is fed from the output of the trigger 23, to the input of the element And and the input of the S-trigger 23, confirming its single state.

Through the open element And 16ij information from the output of the counter 12 PA

is simultaneously recorded in counter IV.

In the counter 20 j transitions 1 enters the S-input of the trigger 23, confirming its single state.

In counters 19 and 19z of the transitions, the pulse arrives at the inputs of the And 25 elements, from whose outputs nothing arrives, since the other inputs from the outputs of the flip-flops 23 are given a zero potential.

If the operator performs operations in the same zone, then the search time for the item is recorded accordingly. 16 for the first, counters 16J for the second, and counters 16} for the third zone.

With the subsequent operations of the operator, the operation of all elements and blocks is similar.

During the work of the operator, for each zone separately, the total time of access is counted in blocks 3 for measuring the duration of intervals, in counters 5 - the number of visits to this zone, and also in the counter 6 for the number of transitions - the number of transitions from one zone to another.

After the operator performs all the operations stipulated by the experiment program, he presses the Stop button (not shown) in the operator’s console 7, the signal from which enters the readings of the inputs of the interval duration measurement units 3, rewriting the information into the registration unit 8 and blocks 5 and 6, the signals from the outputs of which are fed simultaneously to the inputs of the dividing units 18 | -18t, and 15–15z, set their division factors and to the inputs of the elements 13 and 16, the passage through which the information in the counters 14 and 17 is read input is appropriate their blocks 15 and 18 divisions.

11 obtained as a result of dividing the information from the outputs of the blocks (-, and 18, - 18 y, the division enters the inputs of the registration block 8. Thus, in the counters (not shown) of the registration block 8, receiving information from the division blocks, the average search time is fixed elements when the operator goes from one zone to another, and in the first counter - from the first zone to the second and vice versa, in the second - from the first zone to the third and vice versa, in the third - from the second zone to the third and vice versa, etc., and the counters corresponding to the dividing blocks fix the average time search elements for handling operator in the same zone, the first zone to the first counter for the second - in the, second, to the third - in the third, etc.

Based on the indications of the registration unit 8, based on the ergonomic requirements for the consoles, the operator makes a conclusion about the suitability of the bullets

This is to be operated from the point of view of convenience, and also gives recommendations on the revision of the location of individual controls.

The use of the device allows to improve the quality of recommendations when evaluating workplaces by determining the time of search for items

in the same zone and when moving from one zone to another.
