Description

A subscriber polling device is a technical device intended for collecting and processing information in sociological and sociopsychological studies. Its field of application may be to automate a questionnaire and other labor-intensive operations of collecting, transforming, expressing and preparing for the processing of sociological information on a computer, studying the structure and dynamics of the development of groups, identifying groups and leaders, evaluating and evaluating individual socio-psychological factors. qualities and visions, etc. According to the principle of operation, the proposed device relates to computing technology.

According to the main author. St. No. 511583, a device for polling subscribers is known, comprising a pulse generator, the output of which is through a serially connected element I and a two-position switch, to the second input of which, via a first pushbutton switch, a zero potential bus is connected to the input of a pulse distributor, one output of which is connected through serially connected second pushbutton the switch and the OR element is connected to the second input of the AND element, the second output of which is connected to the first input of the display unit, and the remaining output The corresponding outputs of the subscribers are connected to the input of the corresponding outputs of which are combined and connected to the corresponding inputs of the display unit and the response comparison unit with the reference, the output of the response comparison unit with the reference is connected to the corresponding input of the display unit through the counter, the inputs of the subscriber control unit are connected to the outputs of their individual control, and the output is connected to the second input element OR. As part of the device, the block for comparing answers with: the reference contains:

20 elements NOT and two-position switches according to the number of block inputs, multi-position switch, AND element and toggle switch connected between block output and AND element output, inputs

25 of which are connected to the outputs of the corresponding two-position switches, one outputs of which are connected to the appropriate inputs of the block, and the second through 30 the corresponding elements NOT, the inputs of the multi-position switch are connected to the corresponding inputs of the block, and its output is connected to the second output of the toggle switch 1. Disadvantages of the known devices, the lack of separation of respondents by characteristic social groups, as well as low reliability of the device during the time of the survey cycle. The lack of classification of respondents by characteristic social groups narrows the boundaries of using automatic methods for mass polling of subscribers, since such a survey is actually possible only in homogeneous groups and teams. Such social characteristics of the respondents, such as gender, age, official status, education, partisanship, etc. represent their socio-psychological characteristics taken into account in the subsequent processing and analysis of data. The ability to automatically assign these features greatly expands the scope of application of the device and increases the quality of the conduction test. This dramatically increases the amount of manual maintenance of the device, which is also the reason for their automation. The reliability of the known device is low, during a polling cycle (1.5–2 s) due to interference from the power supply circuit, due to the discrete connection to the power supply at this time of current collectors in the form of indication lamps connected to counters and registers. . The processes of reception-transmission, accumulation, and dumping of binary information on them leads to various randomly varying combinations of the total load on the power supply circuits with their random distribution by locations in the device circuit. As a result, during a short time of the polling cycle, characterized by intense transients in all units and nodes of the device, interference occurs in the power supply lines, affecting their reliability at this time. This effect is due to significant pulse currents in conductors connected to indication lamps (about 18 pcs.), Each of which consumes a current comparable to the current consumption of the rest of the electronic part of the device. The purpose of the invention is to increase the reliability of work. The goal is achieved by introducing a second pulse generator, a second counter, a second two-position switch, a third switch, an amplifier, single-channel switches, and a starting relay, and the output of the second pulse generator is connected to the starting relay and the second contact of the second switch; the second counter, the outputs of which are connected to the additional inputs of the block comparing the answers to the standard and to the input of the display unit, the output of the second pulse generator The second contact of the second two-position switch and the third pushbutton switch are connected in series with the zero potential bus; through single-channel switches connected to the inputs of the subscriber control unit. The drawing shows a functional diagram of the device. The device contains a pulse generator 1, element AND 2, element OR 3, first two-position switch 4, first and second pushbuttons 5 and b, distributor 7 pulses, unit 8 for comparing responses with a standard, outputs 9 for pulse distributor, first counter 10, unit 11 for indication , subscriber control unit 12, detachable connections 13, individual remotes 14 subscribers, amplifier 15., second counter 16, generator 17 emuls, second two-position switch 18, third, push-button switch 19, starting relay 20 with normally closed contacts ktami one-channel switches 21 and 22 (FIG. 1). The device works as follows. The pulses from the generator 1 through the elements 2 and the first two-position switch 4 are fed to the input of the distributor 7, the outputs of which form the polling priority signals. In connection with the aforementioned one, the individual consoles of 14 subscribers are polled sequentially. Since their like-named outputs are combined, codes on all the numbers of the subscribers being polled appear on the buses connecting these outputs. These codes arrive at block 8 of comparing answers with a standard, where they are compared with a reference code, set by the experimenter. Cases of coincidence of codes are recorded by the output pulses of block 8, which are counted by the first counter 10,

The counter 10 display is indicated by the display unit 11.

The zeroing of the first counter 10 after each polling cycle is performed by a pulse from zero output 9 of the distributor 7, immediately following the series of polling pulses of the individual consoles of 14 subscribers. The device provides for disconnection of part of the control unit 12, belonging to one or another zone of the reference code by means of single-channel switches. In this way, it is possible to introduce specific, selected by the operator, reference code zones into the scope of the control system.

The joint operation of all blocks and elements of the proposed device implies their synchronous actions. After the subscribers dial the response codes on their individual consoles 14, the second pulse generator 17 is activated, producing pulses with a long repetition period. With the arrival of one such impulse at the input of the second counter 16, a new value of the reference code is set on it (for the entire time of the next polling cycle. This impulse receives the coil of the relay 20. After the delay time of the relay, during which the counter 16 is passed transitional processes, normally closed contacts 21 of the relay are briefly opened, having started the device just as it does when the start button 6 is pressed.

All the time when there are pulses at the other outputs of the distributor 7, a potential is produced at its n + 1 output, which is permitting the operation of the AND 2 element (to continue the survey) and prohibiting the operation of the display unit 11, which is provided by the amplifier 15. continuation of the survey cycle (1.5-2 s) all display elements c. Bleshke 11 are de-energized, which increases the reliability of the proposed device at this time, since during the interrogation cycle in all its blocks transients that do not require indication occur. At the end of the cycle when the result is ready, the display system is turned on.

After the operator reads the display of the first counter 10 by means of the display unit 11, the polling cycle with this reference code is considered complete, and after the repetition period has elapsed, the second pulse generator 17 outputs another pulse arriving at the input of the second counter 16 and the winding of the starting relay 20. As a result, the counter 16, a new code value is set, and the polling cycle is repeated as described above. The magnitude of the pulse repetition period of the generator 17 is selected and set by the operator; it can be chosen to be 3.5 or 7 s. In addition, the operator has the possibility of switching the on-off switch 18 to switch from automatic to semi-automatic method of setting reference codes, when with each pressing of the push-button switch 19 a pulse is output to the input of the second counter 16 of the reference code and the winding of the starting relay 20.

After polling the last subscriber at one of the outputs 9 of the distributor 7, a signal appears that through the element OR 3, the second pushbutton switch 6 and the contacts 21 of the starting relay 20 enters the input of the AND 2 element as a suppressive potential, preventing further passage of pulses from the generator 1 to the input of the distributor 7. The poll is canceled. A similar effect takes place from the side of the control unit 8, if it develops a prohibiting potential in the event that one of the monitored codes does not meet the established criterion. To start the proposed device, it is sufficient to briefly remove from the input of the element AND 2 inhibit potentials

Thus, in the proposed device, an automatically and automated method of setting reference codes is provided, while simultaneously taking into account the features of the social integrity of the interviewed subscribers. This provides for the preservation of all functional capabilities by the manual method of specifying the ethnode codes that a known device possesses.
