Description

one

The invention relates to the field of pedagogy, physiology, and psychology of labor and sport and can be used to determine temporal indicators of work in the educational, labor and sports activities of a person.

In order to establish technically sound standards for the performance of individual operations in production, timekeeping of labor operations of a group of workers is carried out.

Devices for determining the operating time are known, consisting of a recording (recording) device, control consoles, portable consoles and sensors.

The disadvantage of these devices is the difficulty of timing.

Simplification of timing with the help of the proposed device is achieved by introducing differentiating values into it, two waiting relaxers, two amplifiers, and two resistor dividers. The input of each of the differentiating circuits is connected to one of the portable consoles, the output of the starting circuits through the separating diodes is united by a common length and connected to the input of the first waiting relaxer. A first amplifier is connected to the output of this waiting relaxator, the load of which is an electromagnetic relay. The contacts of the electromagnetic relay during its operation connect

The drawing shows a block diagram of the device, where C-Lo is portable consoles; - differentiating chains; 3 - the first waiting relaxer; 4 - the first amplifier; 5 - relay; 6 - schagovy finder; 7 - current divider; 8 - time relay; 9 - pulse counter; 10 second amplifier; II-second waiting relaxer; 12 - pulse generator; 13 - the second current divider resistors; 14 - the registrar; 15 and 16 - the first and second switches; 17i-172i - diodes; 18 - button with normally open contacts. The device works as follows. Z-bo portable consoles are keys with normally open contacts. These keys are mounted on a stand and each of them is connected to the input of one of the differentiating circuits 2i-221 by two insulated conductors of such length that the li-bo control panels can be placed in the workplaces of the subjects. RC differentiating circuits, the outputs of which through dividing diodes 17i-172i are connected by a common bus, which is connected to the input of the first waiting relaxator of a fadron type. The output of the first relaxer 3 is connected to the input of the first one-stage 3

First, ycn.i: Tc ;; s: -, the load of which is electro-p1T; 5 relay; the contacts of this relay, when it is connected, connect the winding 1; at the step 1 pc; nx: 1 G to the power supply (in the drawing not shown). Two resistor dividers 7 and 13 assembled from MLT resistors are connected to two parallel groups of contacts of the step finder 6.

Resistors of current divider 7 are chosen such that with the progressive movement of the slider of the step finder 6 to achieve a linear step change in the current flowing through the recorder 14. This change must be such that at each moment of time its current value is directly proportional to the number of workers and lyh.

A current divider 7 is connected to the source of the filament (not shown in the drawing).

The stepper finder engine 6, to which divider 7 is connected, is connected to one of the contacts of switch 15 (toggle switch), with which recorder 14 is connected either to divider 7 or to the output of time relay 8, which is a symmetrical relaxer with emitter connected to its output repeater. This relaxator is tuned to two fixed and discretely variable frequencies — 0.1 and 1 H.

The resistor current divider 13 is included in the basic circuit of the pulse generator 12 and is intended for a stepwise linear change in the frequency of the pulses generated by the impulse generator. This change must be such that it is current; its generator frequency value is directly proportional to the number of subjects being continued, their work is currently in progress.

With the aid of the divider 13, the pulse generator 12 is tuned to fixed frequencies: 20 Hz, 19 Hz, and so on - up to 1 Hz. The resistors of the dividers 7 and 13 are selected in such a way that, when the stepper sear engine 6 moves progressively, the current flowing through the recorder 14 and the frequency of the generator pulses 12 are stepwise and linearly reduced.

The output of the pulse generator 12 is connected to the input of the second waiting relaxer 11, and to the output of the relaxer And connected to the second single-stage amplifier 10, the load of which is the pulse counter 9.

The counter 9 is connected to the relay amplifier 10 through a switch 16 (toggle switch), the contacts of which are in the initial state open. The second pairs of contacts of the switch 16 are connected in parallel with the contacts of the button 18, which has normally open contacts.

The principle of operation of the device is that after the end of the operation, the subject switches on the key of his console b-l2o. This way he connects the power source to the corresponding differentiating circuit 22-221 connected to this panel. On out4

The tenth circuit is a pulse, which, through dividing diodes 172-172i, receives a common bus B and triggers the relaxer 3. The latter generates a pulse, the duration of which is chosen sufficient for one response of the step finder 6 (50-100 ms). This pulse goes to the first amplifier 4. Electromagnetic relay included in the collector circuit of the transistor

10, the amplifier 4, operates and connects the windings of the step finder 6 to the source of power with its contacts. The engines of the step finder 6 move to the following positions, non-switch dividers 7 and 13. Thus, the end of each test is caused by the forward movement of the sliders of the step finder 6, causing a linear step change of the current flowing through the recorder 14, and a linear step

0 change the frequency of the pulse generator 12. The pulses from the generator 12 arrive at the second relaxer 11 and start it. The duration of the pulses of the second waiting relaxator (several tens of milliseconds) is chosen from considerations of the stable operation of summing counter 9 at the upper frequency generated by the generator 12 (10 Hz).

Before the start of the time-keeping process, the engines of the quill finder 6 are set

0 to its original state using button 18. In this case, the circuit works in the same way as in the exploded case with the control panels of the subjects. The engines of the spider finder 6 are set to the position of n -} - 1 subjects (where n is the number of subjects participating in the experiment).

The switch 16 in its initial state breaks the circuit of the pulse counter 9. Simultaneously with the signal of the subject at the beginning

0, the operation of the switch 16 closes the circuit of the pulse counter 9, and the differentiating circuit 2 is connected to a power source. As a result, the step finder 6 is set to a position corresponding to the number of subjects participating in the experiment (p). Summing counter 9 begins to register pulses, and on the recorder 14, the beginning of the process is noted. To calibrate the recorded khropometry process, the recorder is connected to time relay 8 using switch 15.
