Description

one

Nowadays, in higher and secondary educational institutions, devices are widely used for training and monitoring student titles, which contain reading, entering of answers, entering of a ticket number, indication, printing, etc.

However, the design and electrical circuit of the reader do not allow the use of existing standard punched cards, since recording the information on the latter is possible only in the usual decimal calculus, and this in turn forces either to increase the size of the punched card or to reduce the amount of information entered into the device . The use of non-standard punched cards eliminates the possibility of mechanizing the process of manufacturing the last and inserting holes on them (the correct answer code), and this is a very laborious work and prevents more widespread introduction of the device into the educational process.

The ticket number node is mechanically connected to the print node (digital wheels rotate with the help of cables), which complicates the cumbersome design of the ticket number input node and its connection to the print node.

The lack of communication between the input input node and the print nodes and the display significantly reduces the device’s capabilities, as the information given by the print node (four digits in total: the first three are the ticket number and the fourth is the score) is insufficient for collecting static data and further exam analysis. The lack of visual control deprives the examinee or another person of the opportunity to check in the process of entering, how many “good answers are entered, whether a mechanical error is made while entering, etc.

The connection of the response input node with the comparison node in the input process does not allow: a) to enter answers in any sequence, b) to enter only part of the answers, c) if an error is detected, without discarding the previously entered information, correct it, etc.

The purpose of the invention is to increase the effectiveness of training.

The proposed device is characterized in that one of the outputs, the input unit is connected to the display unit, and the other to the printing unit. The readout unit is made up of serially connected decoders, each of which is connected to a contact plate, which is connected to the cassette and which is used to analyze the node.

On the fit. 1 is a block diagram of the device, in FIG. 2 - functional diagram of the reader.

The device contains a reading unit 7, an input unit 2,; a comparison unit 3, an adder 4, an evaluation unit 5, a display unit 6, a printing unit 7. The reader has a cassette 8, a contact board 9, a decoder W-il2, interrogating node 13.

A reading unit consists of a cassette that can be used (with which; A card is inserted into the device; a contact board, the contacts on which are closed by pins that drop out of the cassette at the holes on the punch card; binary code to decimal decoders; a start relay for polling the contact board series.

The comparison unit is a group of relays that turn on, and the coincidence of the signals received by the input unit.

The input block is made in the form of switches on 11 positions.

Adder - contact groups of relays in the form of a pyramidal adder.

The evaluation unit is a six-way switch by which the number of questions is established and the evaluation criterion is derived.

The display unit contains digital indicators to record the information entered, signal lamps to record the correct answers, and one indicator to give an overall assessment.

The printing unit is a typewriter "Moscow," Ukraine, "Consul or Kaka or Friend.

After entering into the reading unit of the punch card with the ticket number and the correct answers code, the student (the examinee) dials the number of the ticket with the switches of the input box, which is compared with the record on the punch card. If there is a match, further input is allowed. In this case, all information entered by the students in the device is recorded on the indices block. This allows you to check.

in the process; input the answers and, if necessary, correct and exclude an accidental mistake. After entering all the answers, the student clicks the button to turn on the comparison unit, the adder, the evaluation unit and the printing unit. The comparison unit receives information from the first row of the reading block and the first switch of the input block, then from the second row and the second switch

And so on. Lri each coincidence of the readings of the reading unit with the position of the switch, the input unit l passes through the level unit and the pulse into the adder where points accumulate, and at the end of the cycle through the evaluation unit

general evaluation is derived. At the same time, the responses entered by the students are printed, after each answer the letter "B (true) or" H (incorrect) and at the end - a general assessment. On the display unit against each response, a signal lamp lights up (if the answer is correct), and the digital indicator | p gives an overall rating. When you see a punch card, the device automatically returns to its original position.
