Устройство для контроля знаний обучаемых работает следующим образом .A device for monitoring the knowledge of students is as follows.

С пульта 1 в блок 2 заносятся коды эталонных ответов, а каждая ячейка этого блока содержит код одной цифры результата или одного символа конструируемого ответа. Кроме того, с пульта 1 поступает сигнал на соответствующий счетчик блока 3» устанавливающий такой коэффициент пересчета, при котором поступление, например на 1 —й счетчик -сигналов правильного ответа, вызвало бы появление на выходе i-ro счетчика сигнала переноса, означающего, что весь ответ введен i-м обучаемым верно» fOCodes of the standard answers are entered into unit 2 from the console 1, and each cell of this block contains the code of one digit of the result or one character of the constructed response. In addition, remote control 1 receives a signal to the corresponding counter of unit 3 ”, which sets such a conversion factor at which the arrival, for example, at the 1st counter of the correct answer signals, would cause the transfer signal to appear on the i-ro output, which means that the whole the answer is correctly entered by the ith student »fO

В начальный момент времени триггер 16 находится в нулевом состоянии, что обеспечивает поступление тактовых импульсов с генератора 23 через элемент 21 на сдвигающий вход регистра 24, в котором единица разрешаетAt the initial time, the trigger 16 is in the zero state, which ensures the arrival of clock pulses from the generator 23 through the element 21 to the shift input of the register 24, in which the unit allows

976469 6 поочередно прохождение сигнала через элементы И блока 12, на другие входы которых поступают сигналы готовности от пультов 27.976469 6 alternately passing the signal through the AND elements of block 12, the other inputs of which receive ready signals from the consoles 27.

Если i-й обучаемый выполнил тестовую задачу, то он с помощью блока 11 вводит очередной элемент своего ответа (цифру, код символа контр, ответа) . Введенный код запоминается в регистре 10 и переводит триггер 9 в сос· тояние, запрещающее ввод очередного символа, причем сигнал готовности к обслуживанию, снимаемый с прямого выхода триггера 10, поступает на i-й элемент И блока 12. В момент появления в i-ом разряде регистра 24 единичного потенциала этот сигнал готовности адресует соответствующий регистр в блоке 2, чем обеспечивает сдвиг содержимого очередной ячейки регистра через элемент 20 в регистр 18, также сигнал через элемент 15 устанавливает триггер 16 в состояние, разрешающее прохождение тактовых импульсов через элемент 22, и запрещающее - через элемент 21.If the ith student completed the test task, then using block 11, he enters the next element of his answer (number, symbol code counter, answer). The entered code is stored in register 10 and puts the trigger 9 in a state that prohibits the input of the next character, and the signal for readiness for service, taken from the direct output of trigger 10, goes to the i-th element of block 12. At the moment of occurrence in the i-th the discharge of the unit potential register 24, this ready signal addresses the corresponding register in block 2, thereby shifting the contents of the next register cell through element 20 to register 18, and the signal through element 15 sets trigger 16 to a state that allows tovyh pulses through the element 22, and prohibiting - through member 21.

Таким образом, единица в регистре 24 зафиксирована и с выхода i-ro элемента И блока 12 сигнал разрешения поступает на элементы 13 и 14 i-ro пульта 27. С выхода элемента 22 тактовая серия из десяти импульсов (фиг. 2), что регламентируется счетчиком 17, поступает через элемент 13 на вход счетчика 25 i-ro пульта 27.Thus, the unit in register 24 is fixed and from the output of the i-ro element And block 12, the enable signal is sent to elements 13 and 14 of the i-ro remote 27. From the output of element 22, a clock series of ten pulses (Fig. 2), which is regulated by the counter 17, enters through the element 13 to the input of the counter 25 i-ro remote 27.

Коды, формируемые при этом на счетчике 17 и счетчике 25» сравниваются на совпадение соответственно в узлах 19 и 26 с кодами в регистрах 18 и 10. В момент сравнения узел 19 выдает сигнал, соответствующий по времени k-му сигналу тактовой серии, где к - число соответствующее эталону данного символа и хранится в регистре 18 (на фиг. 2 пример для формирования к=5). Этот сигнал поступает через открытый элемент 14 на элемент 7, где анализируется, произошло ли на к-ом такте, совпадение в узле 26.The codes generated in this case on the counter 17 and the counter 25 "are compared for coincidence in nodes 19 and 26, respectively, with the codes in registers 18 and 10. At the time of comparison, node 19 produces a signal corresponding in time to the k-th signal of the clock series, where k is the number corresponding to the standard of this symbol is stored in register 18 (in Fig. 2 an example for the formation of k = 5). This signal is transmitted through open element 14 to element 7, where it is analyzed whether a coincidence at node 26 occurred at the k-th beat.

Если совпадение произошло, то сигнал с элемента 7, означающий, что введен верный элемент ответа, поступает через коммутатор 6 в 1-й счетчик блока 3, а также через элемент 8 - на сброс триггера 9. Если же совпадения нет, т.е» обучаемый ввел неверный символ, то после 10-го такта с выхода счетчика 25 через эле-, мент 8 на триггер 9 поступит сигнал сброса, разрешающий обучаемому дальнейшую работу. В этот же момент сиг- ₍нал переполнения со счетчика 17 сбро-'5 (Сит триггер 16 и регистр 18, чем обеспечится подключение следующего пульта 27.If a match has occurred, then the signal from element 7, which means that the correct response element is entered, is sent through switch 6 to the 1st counter of block 3, and also through element 8 to reset trigger 9. If there is no match, that is, ” the student entered the wrong character, then after the 10th step from the output of counter 25 through element 8, trigger 9 will receive a reset signal, allowing the student to continue working. At the same moment The signal _(NAL overflow from the counter 17 Throw-'5 (Seet flop 16 and register 18, thus enabling the next remote connection 27.

Таким образом будет производится посимвольный опрос обучаемых» ¹⁰ Thus, a character-by-character survey of trainees will be made. ” ¹⁰

По мере выполнения обучаемыми заданий формирователь 4 будет оценивать состояние счетчиков блока 3 и формировать¹ результаты контроля знаний для вывода с помощью блока 5. ^<SУстройство обеспечивает адаптацию к уровню работы обучаемого,создавая при этом равные возможности для всей группы (так как опрашиваются в2е пульты последовательно).As the students complete the tasks, the shaper 4 will evaluate the status of the counters of block 3 and generate ¹ knowledge control results for output using block 5. ^<S The device provides adaptation to the student’s level of work, creating equal opportunities for the entire group (since the remotes are interrogated sequentially).

Однако обучаемые, работающие с повышенной скоростью, будут чаще представлять свои результату для контроля и быстрее закончат выполнение задания.However, students working at an increased speed will more often present their results to control and finish the task faster.

По сравнению с известным повышено быстродействие устройства, обеспечивающее сравнение с эталоном в процессе ввода ответа, т.е. исключается режим проверки задания каждого обучаемого, что позволяет сократить время обработки результата ответа для успешно работающего обучаемого более чем в 2 раза.Compared to the known one, the device’s performance is improved, which provides a comparison with the standard during the response input process, i.e. each student’s task verification mode is excluded, which allows to reduce the processing time of the response result for a successfully working student by more than 2 times.

The elements 7, B, 13, and 1, block 11, register 10, trigger 9, counter 25, and node 26 are integrated into the student console 27. The elements 15t 21 and 22 and the trigger 16 are a pulse distributor 28, a counter 17, a register 18, a node 19 and an element 20 combined into a pulse shaper 29. The device for controlling students' knowledge works in the following way. From unit 1, unit 2 records the codes of reference responses, and each cell of this unit contains a code of one digit of the result or one symbol of the constructed response. In addition, from console 1, a signal arrives at the corresponding counter of block 3, which establishes such a conversion factor, at which the arrival, for example, the correct response of icj-signals to the i-counter, would cause a transfer signal at the i-ro output, meaning that the entire answer is entered by the 1st student faithfully. At the initial moment of time, the trigger 16 is in the zero state, which ensures the arrival of clock pulses from the generator 23 through the element 21 to the shift input of the register 2, in which the unit permits alternately passing of the signal through the AND section 12, to another input which receives the enable signals from remote 27. If the i-trained and performed a test task, it via block 11 enters the next element of its response (figure counter code symbol response). The entered code is stored in the 1P register and translates the trigger 9 into a state prohibiting the input of the next character, and the ready-for-service signal taken from the direct output of the trigger 10 enters the i-th element of AND 12. At the moment of its appearance in This unit ready signal addresses the corresponding register in block 2, thereby shifting the contents of the next register cell through element 20 to register 18, and the signal through element 15 sets the trigger 16 to a state that permits the passage Actual pulses through the element 22, and prohibiting - through the element 21. Thus, the unit in register 2 is fixed and the output of the i-ro element AND block 12 signal resolution goes to the elements 13 and 1 of the i-ro console 27. From the output of the element 22 clock series Of the ten pulses (Fig. 2), which is regulated by counter 17, enters through element 13 to the input of counter 25 of the i-ro console 27. Codes formed in this case on counter 17 and counter 25 are compared for a match, respectively, at nodes 19 and 26 sec. codes in registers 18 and 10. At the time of comparison, node 19 generates a signal corresponding to uyuschy time k-th clock signal series where k - corresponds to the reference number of the symbol and stored in the register 18 (FIG. 2 example to form). This signal comes through the open element H to element 7, where it is analyzed whether the k-OM cycle occurred, a match at node 26. If a match occurs, then the signal from element 7, which means that the correct response element is entered, goes through switch 6 in The 1st counter of block 3, as well as through element 8, is used to reset the trigger 9. If there is no match, i.e., the trainee entered the wrong character, then after the 10th 73 clock cycle from the output of the estimator 25 through element 8 to the trigger 9 a reset signal will be received, allowing the trainee to continue working. At the same time, the overflow signal from counter 17 is reset, trigger 16 is set, and register 18 ensures the connection of the next control panel 27. Thus, a character poll of the students will be performed. As the students perform tasks, the if driver will evaluate the state of the block 3 counters and generate control results knowledge for output using block 5 "The device provides adaptation to the level of the student's work, thus creating equal opportunities for all groups (as the pools are polled sequentially). However, trainees who work at higher speeds will more often submit their results to the control and finish the task more quickly. Compared to the known, the device speed is improved, providing a comparison with the reference in the process of entering the answer, Toe excludes the test mode for each student, which reduces the processing time of the response for a successfully working student by more than 2 times.
