The drawing shows a structural diagram of the proposed device. The device for controlling the students' knowledge contains the consoles 1 learners, the learning information input unit 2, the first output connected to the first input of the learning information memory unit 3, the second output to the control information storage unit 4, the output of which is the first input of the consoles 1, and the second input is connected to the accumulating 5 address counter, the first input of which is connected to the first output of block 2 of the educational information water, and the second input is connected to the output of a tunable counter of 6 characters, which is also connected to the accumulation This zone counter 7 and the second input of the console 1. The second output of the counter 6 and the output of the counter 7 are connected to the block 3, the output of which is connected to the third inputs of the consoles 1, the outputs of which are connected to the output of the training information 8, are connected to the first input of the counter 6 the output of block 4, and the second input - the element OR 9, the first input of which is connected to the first output of the block 2, and the second, as well as the fourth inputs of the consoles 1 are connected to the element 10, the first input of which is connected to the generator 11, and the second - to the third input of block 2. Each console 1 contains a response input unit 12, the first output of which is connected to the first input of the comparison unit 13 and the first input of the AND element 14, the second input of which is the fourth input of the console 1, and the output, as well as the second outputs of the block 12, are also connected to the memory block 15 responses are connected via the OR 16 element to the input of the address counter 17, the outputs of which are connected to the second inputs of block 15, the output of which is connected to the second input of comparison unit 13, the third input of which is the third input of the console 1, and the output is connected to first entry tunable with There are 18 correct answers, the first input of which is connected to the first input of console 1, and the element 19 is connected to the third input. The first input of element 19 is the second input of console 1, and the second input through inverter 20 and element 21 is connected the outputs from 1 detector 18. The output of the element 21 is the outlet of the device 1. The device operates as follows. In block 3 of block 2, the codes of response standards are entered, and simultaneously in block 4 control information is entered that determines the number of response symbols in this variant of the answer. This information controls the counter 6, which determines the address of the reference, which is carried in block 3 at the moment. After the overflow of the counter 6, the pulse increases the contents of the counter 7, which ensures that the next option is entered into the new zone of block 3. After all the information has been entered, the students are given the opportunity to answer questions. Block 2 receives a Poll signal, the Tutor enters the response using block 12. The incoming character code through element 16 increases the contents of counter 1 and is entered into the appropriate place of block 1b. After the input of the entire sequence of response symbols is completed, the learner sends a ready signal from block 12 that permits comparison operations in block 13. Formed signal Polling allows receipt of clock ings from generator 11 to all consoles 1 and through element 9 to the second input of counter 6 As a result, from. unit 3 to the trunk connected with all the blocks 13 of the consoles 1, the reference codes of characters alternately arrive. From block 4 at this moment the code of the number of correct answers dp of this variant is removed. This code provides the setting of the meter 18 of the remote control 1 for the number of correct answers of this variant. The clock signal of each character enters through elements 0 and 14, and on condition that the console 1 is ready, the address 17 symbol stored at block 15 is synchronously generated. Thus, block 13 consistently compares the character codes that come from block 15 and from the trunk connected to block 3. When these codes coincide, the pulse 18 enters the counter 18 of the gun 1. If during the comparison of symbols located in one zone of block 3, the counter 18 is not filled with ones, then the next signal from the counter b, meaning the Transition to the next zone of block 3, resets this counter 18 to zero. If in the process of comparing the standards of one zone and the responses of the student, the counter 18 is filled with units, then the signal is removed from it. The correct response is received in block 8 and prohibits the reset of this counter 18, which prevents the repeated polling of this console 1 in the current monitoring cycle. After a certain time-out for the control of one question, the timer (not shown) will generate a signal that resets the block 15 and the counters 14 and 18 of all the consoles, thus allowing the user to enter the answer to the next question. The device repeats the operations described above. The device allows simultaneous monitoring of all trainees in all the variants sequentially, which ensures the elimination of unproductive operations for accessing a particular console. The proposed device allows to increase the speed, as it reduces the time of knowledge control. The control time of a known device is represented as a counter.
