Description

The invention relates to automation and computing, in particular to devices for monitoring students' knowledge, and can be used in various educational institutions.

According to the main author. St. No. 756460 a device is known that contains a response input unit connected to the question register and an answer comparison unit connected directly to an error counter, and via an answer encoding unit to a question register connected to an indication unit connected to one of the evaluation recorders connected to the control unit, two keys, one of which is connected to the error counter and the response comparison unit, and the other to the evaluation registrars and the response input unit {1J. However, the known device cannot work with reference to the time, which is necessary, for example, when passing examinations for the right to drive a car, when practicing skills in emergency situations and other cases.

The purpose of the invention is to expand the didactic capabilities of the device.

This goal is achieved by inserting in series a mode switch, a threshold element, a response termination signal switch, and a separating element connected to the input of one of the evaluation recorders.

The drawing shows a device for the control of knowledge of the uchash, their.

The device contains a register of 1 questions, a block 2 for encoding answers, a block 3 for entering answers, a key 4, a block 5 for comparing answers, a counter 6 errors, a key 7, a block 8 for indication, registrars 9 and 10 evaluations, control switches 11 and reset 12, placed in the control unit 13, the buses 14-17, through which the device is connected to the control panel 18, to which several monitoring devices are connected, the threshold element 19, the separating element 20, the response termination switch 21, the operation mode switch 22 and the power source 23.

Register 1 indicates the number of the answered question and, via block 2, connects the output of the answered question to one of the outputs of block 3, by means of which the answers are entered into the device.

The output of block 3 is connected to register 1, which switches to the next question when selecting the answer in block 3. The input of block 3 is connected to key 4, which disconnects power from block 3 when the evaluation signals "Pass or Fail" fails and locks register 1 when choosing answers.

A block 5 is connected to the inputs of block 3, which selects signals of incorrect answers, the number of which is registered by a counter 6

errors, including by means of key 7, the result of the answers “Did not pass.

Switch 11 turns off the recorders 9 and 10 and the key 4 when operating in the “Self-control of knowledge. Switch 12 is used to set the device to its original position when operating in the “Self-knowledge control” mode.

On the device power bus 14, a constant voltage is applied when operating in the Control and Pulsating mode in the Self-Control mode.

Signals are sent to bus 15 for the "Self Test and" Exam. Tires 16 and 17 are used to display the result of responses and signals “Pass - Finish,“ Did not pass - Error.

The device works as follows

In the Control mode, bus 14 of block 13 is supplied with constant voltage. No signals are sent to bus 15.

In the register I indicates the digit “1, the number of the first question. The output of the first question from the register I through block 2 is connected to one of the outputs of block 3 of the input of answers, while only one of these outputs is given a signal (potential). The student answers the question by choosing the correct answer number of one of the buttons of block 3. If the answer is correct, then the signal (potential) from key 4 through the pressed answer button goes to the output of block 2, I have, the same signal (potential) from the first question.

Block 5 does not respond to these signals. When the button of the selected block 3 response is released, the signal goes to register 1 and it switches to the second question.

If the answer is incorrect, then the signal (potential) from block 3 when entering the answer is highlighted by block 5, passes to the input of counter 6, where an error is recorded.

When releasing the button of the answer of block 3, register 1 switches to the third question h, etc.

If the number of errors is greater than the allowable number, then the counter 6 turns on the key 7.

At that, key 4 is turned on, power is removed from block 3, and further operation of register 1 and counter 6 is blocked. Registrar 10 indicates a rating "Not passed, such an estimate is given to bus 17. When switch 12 is turned on, reset" Not passed and key 4 is not reset. happens as they are powered.

If the learner answers the questions correctly or made the number of errors less than the number allowed, then after answering the last question, block 8 is turned on and registrar 9 is turned on (“Passed).

In the "Self-control (training)" mode, the device operates as follows.

A pulsating voltage is applied to the outputs of block 13, and to bus 15, a signal for the Learning mode, the learner answers questions in the same way as in the Control mode.

If the answer is incorrect, the key 7 is turned on, the HHflHUHpyetCH signal is "Error by the recorder 10 and the key 7 is turned off, by disabling which the switching of the register I to the next question is blocked. Learned by the switch 11 turns off the recorder 10, the key 4, the key 7 and again answers the same question. After the correct answer, register 1 switches to the next question, and so on.

After answering the last question, block 8 and registrar 9 are activated - “Graduated.

In the "Simulator" mode of operation, a pulsating voltage is applied to the input of the block 13. Bus 15 is disabled (no signals are sent to it).

The student answers the questions in the same way as in the “Control. If the trainee received the mark "Did not pass, he switch 12" Reset sets the device to its original position and again answers the questions and so on until the score is received. "Passed.

When operating in any of the time-bound modes, after the time interval allocated for answering the ticket questions, the contacts of the switch 21 are closed. At the same time, the element 20 is connected to the reduced voltage of the element 19. Due to this connection, the potential on all the tires 17 decreases, key 7 is turned off and key 4 is turned on and recorders 10 are turned on. Did not pass in those devices in which the trainees did not have time to respond to the ticket.

The inclusion of recorders 10 in those devices where recorders 9 have already been turned on has been passed, eliminated by the fact that recorders 9 and 10 have a common load (resistor)

5 and the bus 17 is not connected to the power supply minus, but to the reference voltage of the element 19.

The invention allows to expand the didactic capabilities of the device due to the additional mode of operation with time-dependent.
