Description

The utility model relates to educational devices and can be used for training, knowledge control and diagnostics of the quality of training in various educational institutions, regardless of the form of training, including with the use of distance technologies, and can also be used in various departments of labor protection and safety organizations.

A device for controlling knowledge, described in [1]. The device comprises a user (trainee) response input input unit, two pulse distributors, a mode control unit (operating mode block), a first summation unit connected in series, a password generation unit and a password display unit (indicator unit), modulo two summally connected unit, the second summing unit and the unit for generating the numbers of the task code, the block of registers of the operational part of the task, the unit for registering the initial part of the task, the unit for generating operands connected in series a switching unit (switch) and a comparison unit, a registration unit, three AND elements, two of which are connected by the first inputs to the outputs of the comparison unit, and by the second inputs to the control output of the user response input unit. The outputs of the two named elements AND are connected to the inputs of the registration unit, the output of which is connected to the control input of the mode control unit. The inputs of the third element And are connected to the output of the first pulse distributor and the output of the mode control unit, and its output is connected to the reset input of the second summing unit. The input of the user response input unit is connected to the control output of the mode control unit, and the outputs of the user response input unit are connected to the inputs of the pulse distributors and to the control inputs of the mode control unit. Entering the task code and answers into the user response input input unit is carried out by pressing one and buttons (keys), each of which is associated with a certain number of characters. Each of the pulse distributors, according to its functions, is connected with the other blocks included in this device, and in the aggregate both distributors combine all the blocks of the device.

The sequential inclusion of two summing blocks during the joint operation of pulse distributors allows for the implementation of multivariate response modes, that is, it allows the principle of code redundancy to be implemented due to the possibility of lengthening the codes. In addition, when using this device, it is possible to recognize the correctness of ambiguous answers and the correspondence to each answer of an unlimited number of task codes is achieved. This extends the logical and didactic capabilities of the device and improves its operational characteristics.

The disadvantages of the device include the fact that it:

- differs in insufficient information content of the password;

- does not provide communication with the computer;

- carries out work only in Russian;

- does not allow visualization of input information:

- excludes the possibility of adjusting the input response without a general dumping of information.

The operational characteristics of such a device are limited, since it cannot be used to automatically process the results of external control.

Closest to the technical nature with respect to the claimed device is a device for monitoring and self-knowledge, containing a block input user response, having seven outputs, a first memory block having first and second inputs connected to the first and second outputs of the block input user response and one output connected to the computer, a code converter having one input connected to the first output of the user response input input unit, and one output, an operating mode block having five l inputs, the first of which is connected to the output of the code converter, and the second and fifth - with the second and seventh outputs of the user response input unit, and having eight outputs, a second memory block having three inputs, the first of which is connected to the output of the code converter, and two outputs, a third memory block having three inputs, the first of which is connected to the first output of the second memory block, and one output, an equality block having five inputs, the first of which is connected to the second output of the second memory block, and one output, block management a reset having first and second inputs connected to the fifth and fourth outputs of the user response input input unit, and two outputs, the first of which is connected to the third inputs of the second and third memory blocks, and the second to the third input of the operating mode block, a switch, having three inputs, the first of which is connected to the second output of the reset control unit, and the third to the eighth output of the operating mode block, and two outputs, the second of which is connected to the second inputs of the second and third memory units, the fourth memory unit there are four inputs, the first of which is connected to the first output of the switch, the second to the second output of the reset control unit, the third to the output of the code converter, the fourth to the computer, and one output connected to the second input of the equality unit, the repeat control unit having four the input, the first of which is connected to the first output of the switch, the second to the output of the code converter, the third to the second output of the reset control unit and the fourth to the fifth output of the operating mode block, and one output connected to the second input switch, the fifth memory block having seven inputs, the first of which is connected to the output of the code converter, the second - with the first output of the reset control unit, the third and fourth - with the first and third outputs of the operating mode block, the sixth - with the second output of the response input block a user, a seventh — with a computer, and one output, a response converter without taking into account the order of inputting numbers, having three inputs, the first of which is connected to the output of the code converter, the second to the second output of the reset control unit, the third to the first the output of the switch, and one output connected to the third input of the equality unit, a password generator having ten inputs, the first of which is connected to the output of the third memory unit, the second with the output of the fifth memory unit, and the third with the output of the response converter without taking into account the order of inputting numbers , the fourth - with the third output of the user response input unit, the fifth and sixth - with the first and second outputs of the reset control unit and the seventh - with the output of the equality unit, and four outputs, the indicator block having thirteen inputs, the first of which is connected to the third output of the operating mode block, the second - with the sixth output of the user response input block, the third - with the first output of the reset control unit, the fourth, fifth and sixth - with the first, fourth and second outputs of the operating mode block, seventh and eighth - with the second and first outputs of the password generator, the ninth - with the output of the equality block, the tenth and eleventh - with the third and fourth outputs of the password generator, and the twelfth - with the first output of the response response input block of the user, and two outputs, the first minutes of which is connected to a fifth input of the fifth memory block, and the second - to a fourth input of block modes [2].

The use of five memory blocks expands the logical and didactic and operational characteristics of the device, as it provides the possibility of computer processing of the results of external control, increases the information properties of the password, increases the possibility of evaluation criteria when testing the user.

However, the prototype device has the following disadvantages. Firstly, it provides for communication only with a computer. And if there is no computer in the room in which the device is used, then it is impossible to transmit information to the device from the computer. This significantly limits the operational capabilities of the device. Secondly, the device does not allow training for schoolchildren when they learn arithmetic. This limits the scope of the device in elementary school and pre-school institutions. Thirdly, when using the device in the classroom, students cannot be identified using this device. This leads to the need to manually enter additional information into the computer after the transfer of test results to it. Fourth, the device does not distinguish between lowercase and uppercase letters. This limits the possibility of implementing the criteria for the correctness of answers in cases where it is required to distinguish lowercase from uppercase. Fifthly, control and self-control in the device is provided only in Russian. Sixth, the device uses a bulky remote standard computer keyboard.

The tasks to which the proposed utility model is directed is the expansion of the functional and operational capabilities of the device for the control and self-control of knowledge.

The solution of the tasks is achieved by the fact that in the device for monitoring and self-control of knowledge, containing a user response input block having seven outputs, a first memory block having first and second inputs connected to the first and second outputs of the user response input block and one output , a code converter having one input connected to the first output of the user response input input unit, and one output, an operating mode block having five inputs, the first of which is connected to the converter output c, and the second and fifth with the second and seventh outputs of the user response input input unit, and having eight outputs, the second memory unit having three inputs, the first of which is connected to the output of the code converter, and two outputs, the third memory unit having three input, the first of which is connected to the first output of the second memory unit, and one output, an equality unit having five inputs, the first of which is connected to the second output of the second memory unit, and one output, the reset control unit, having the first and second inputs connected to the fifth and the fourth outputs of the user response input input unit, and two outputs, the first of which is connected to the third inputs of the second and third memory blocks, and the second to the third input of the operating mode block, a switch having three inputs, the first of which is connected to the second output of the control unit reset, and the third with the eighth output of the operating mode block, and two outputs, the second of which is connected to the second inputs of the second and third memory blocks, the fourth memory block having four inputs, the first of which is connected to the first comm output ator, the second with the second output of the reset control unit, the third with the output of the code converter, and one output connected to the second input of the equality unit, the repeat control unit having four inputs, the first of which is connected to the first output of the switch, the second to the output code converter, the third with the second output of the reset control unit and the fourth with the fifth output of the operating mode block, and one output connected to the second input of the switch, the fifth memory block having seven inputs, the first of which is connected to the output of code generator, the second with the first output of the reset control unit, the third and fourth with the first and third outputs of the operating mode block, the sixth with the second output of the user response input unit, and one output, the response converter without taking into account the number input order, having three the input, the first of which is connected to the output of the code converter, the second to the second output of the reset control unit, the third to the first output of the switch, and one output connected to the third input of the equality unit, a password generator having ten l inputs, the first of which is connected to the output of the third memory block, the second - with the output of the fifth memory block, the third - with the output of the response converter without taking into account the number input order, the fourth - with the third output of the user response input block, the fifth and sixth - with the first and the second outputs of the reset control unit and the seventh with the output of the equality unit, and four outputs, an indicator block having thirteen inputs, the first of which is connected to the third output of the operating mode block, the second with the sixth output of the response input unit the user, the third - with the first output of the reset control unit, the fourth, fifth and sixth - with the first, fourth and second outputs of the operating mode block, the seventh and eighth - with the second and first outputs of the password generator, the ninth - with the output of the equality block, tenth and eleventh - with the third and fourth outputs of the password generator, and the twelfth - with the first output of the user response input input unit, and two outputs, the first of which is connected to the fifth input of the fifth memory block, and the second - with the fourth input of the operating mode block, add a response converter has been introduced taking into account lowercase and uppercase letters, which has three inputs, the first of which is connected to the second output of the reset control unit, and the second and third to the second and additionally entered eighth outputs of the user response input unit, and one output connected to the ninth additional input of the password generator, an arithmetic simulator having four inputs, the first of which is connected to the first output of the user response input unit, the second to the second output of the control unit reset, and the fourth and third with the second and additionally entered ninth output of the user response input unit, and two outputs, the first of which is connected to the additionally entered thirteenth input of the indicator block, and the second to the additionally entered eighth input of the password generator, the sixth block a memory having four inputs, the first, second, third and fourth of which are connected respectively to the first, fourth, second and third outputs of the user response input input unit, and one output, the communication unit with a data acquisition device having four inputs, the first of which is connected to the output of the first memory unit, the second with the additionally entered tenth output of the user response input unit and the third with the output of the sixth memory unit, and four outputs, the second of which is connected to the additional input the tenth input of the password generator, the third with the seventh input of the fifth memory block, the fourth with the fourth input of the fourth memory block, and a data acquisition device (DRC) having one input connected to the first output of the communication unit with USB, and one output connected to the fourth input of the same unit.

Thus, the claimed device differs from the prototype in that the password generator is completely changed and the response converter is added taking into account lowercase and uppercase letters, an arithmetic simulator, the sixth memory block and the communication unit with the DRC, as well as the presence of new connections between the blocks, ensuring the functioning of the device in the modes of external control and self-control of user knowledge by this device.

Due to the introduction of new blocks and new connections between the blocks, it is possible to store all entered information in the DRC with the subsequent transfer of information to a computer, which allows classes in any room, including those not equipped with computers. It does not require the presence of any kind of power network, since the DCU and the claimed device operate from autonomous power sources. Thanks to the block of the simulator of arithmetic operations, the possibility of a “non-standard” technology for performing arithmetic exercises (operations of addition, multiplication, subtraction and division) is provided. External control of these operations is carried out using the advanced features of the password generator. When using the inventive device in the classroom for external control, students are identified using the inventive device itself. To control the implementation of exercises where it is required to distinguish between lowercase and uppercase letters, the device has a corresponding block. Due to the expanded symbolism of the claimed device can be used in any non-Russian schools. In addition, the inventive device uses a built-in rather than a remote keyboard. All this extends the logical and didactic capabilities of the device and improves its operational characteristics.

Figure 1 shows a block diagram of the inventive device. The device comprises a response response input unit of user 1, a first memory unit 2, a code converter 3, an operating mode block 4, a second memory unit 5, a third memory unit 6, an equality unit 7, a reset control unit 8, a switch 9, a fourth memory unit 10, repeats control unit 11, fifth memory unit 12, response converter without taking into account the order of number input 13, password generator 14, indicator block 15, answer converter taking into account lowercase and capital letters 16, arithmetic simulator 17, sixth memory unit 18, communication unit with USD 19 and blo to the USD 20.

To enter numbers and letters of the Russian, Latin and other alphabets, a built-in keyboard is used, the keys of which are the inputs of the input block of the response of user 1. This block contains an encoder, the output of which receives eight-digit binary codes. Block 1 has ten outputs. Its first output is informational and connected to the first input of the memory block 2, with the input of the code converter 3, with the twelfth input of the indicator block 15, with the first input of the sixth memory block 18 and with the first input of the arithmetic simulator 17. The second output is the output of synchronization signals. It is connected to the second input of the first memory block 2, the second input of the operating mode block 4, the second input of the response transformer using lowercase and capital letters 16, the sixth input of the fifth memory block 12, the fourth input of the arithmetic simulator 17 and the third input of the sixth memory block 18. At the second output of block 1, simultaneously with the appearance of an eight-digit binary code on the first output, when a key corresponding to a certain letter or number is pressed, a rectangular synchronization pulse (sync pulse) is formed. The remaining eight outputs of block 1 are control ones; they correspond to the keys: “Control”, “General reset”, “Private reset”, “Password”, “Point”, “Register”, “Simulator”, “Communication with DRC”. When these keys are pressed, a rectangular pulse is generated at the corresponding control output of block 1.

Block 2 is a storage device designed to collect and store all the information entered by the user using the keyboard keys, while the information is stored in a "pure" form, that is, without any special encoding. The output of unit 2 is connected to the first input of the communication unit with USD 19.

Thus, all the information stored in the memory unit 2, after the end of the control can be transferred to the USB, and from it to the computer. This provides the possibility of computer processing of the results of independent work of the student, as well as the ability to visually view the entered information, which is necessary, for example, in cases of appeal.

The code converter 3 is connected to the first output of the response response input unit of user 1. It is a combinational logic circuit that converts the input eight-digit binary codes into binary codes of shorter length. One of the embodiments of the logic circuit of the code converter 3 can be implemented in accordance with Table 1 below.

There are other possible versions of the code converter 3, when the input eight-digit binary codes are converted into binary codes of a different length (not five-digit). The essence of the technical solution does not change

The first code always passes only to the block of operating modes 4 (to the first input). In this regard, in the future, the operation of the device will be considered under the assumption that its operation mode is specified. Five-digit binary codes from the output of the code converter 3 go to the first input of the operating mode block 4, to the first input of the second memory block 5, to the third input of the fourth memory block 10, to the second input of the repeat control block 11, to the first input of the fifth memory block 12 and to the first input of the response transformer without taking into account the order of input of numbers 13.

The block of operating modes 4 contains a binary register formed by triggers A, B, C and D (their outputs are also indicated by the letters A, B, C, D). The single and zero inputs of these triggers receive four-digit binary codes (in parallel) from the output of the code converter 3. The second input of the operating mode block 4 is connected to the second output (synchronization output) of the user response input unit 1. The first clock pulse received from the second output block 1, will overwrite the supplied codes in the register of block 4. In the future, the number in the register will not change.

The fourth input of operating mode block 4 is connected to the second output of indicator block 15. While a high voltage level is maintained at the fourth input of operating mode block 4, all clock pulses, except the first, arriving at the second input of block 4 from the second output of user response input block 1 will be pass to the eighth output of block 4, which is connected to the third input of the switch 9.

The fifth input of the operating mode block 4 is connected to the seventh (control) output of the response response input unit of user 1, to which the “Point” key corresponds. The sync pulse received at this fifth input stops the supply of pulses to the eighth output of the operating mode block 4, as a result of which, when pressed with the key corresponding to the service signs (according to Table 1), clock pulses will not pass to the third input of the switch 9.

The third input of operating mode block 4 is connected to the second output of reset control unit 8. At this input, all triggers A, B, C, and D of operating mode block 4 are set to zero. Using triggers A, B, C, and D, the operating modes of the device are set. A total of 16 modes are possible, which are reflected in Table 2.

In modes with numbers 0, 1, 2 and 3, the task consists of one code, while the indicators “Correct” - “Wrong” work. In modes 4, 5, 6 and 7, the task consists of one code, the indicators “Correct” - “Wrong” do not light. Self-control is done by password. In modes 8, 9, 10 and 11, external control is carried out in combination with self-control. In modes 12, 13, 14, 15 external control is performed without self-control.

The second memory block 5 is an eight-digit binary shift register formed by the triggers 1, 2, 3, ..., 8. The first input of the second memory block 5 is connected to the output of the code converter 3. The second input of the second memory block 5 is connected to the second output of the switch 9. C the output of block 3 to the first input of block 5 receives a four-digit binary number, which, under the action of a clock pulse received at the second input of block 5 from the second output of the switch 9, is written in parallel to the first four triggers 1, 2, 3 and 4 of block 5.

The second number received from the output of code converter 3 is written into the same four first triggers, but the previous number is written into triggers 5, 6, 7 and 8. The first two characters received in the register consisting of triggers 1-8 form job code (KZ). Thus, the second block of memory 5 is a shift register that shifts a binary number with one pulse by four bits. The second memory block 5 has two outputs, the first of which receives an eight-digit binary number in parallel form with rearranged bits, the second - the same eight-digit number, but without rearranging the bits. The third input of the second memory block 5 is connected to the first output of the control unit reset 8. The signal supplied from the first output of block 8, all the triggers of block 5 are set to zero.

The third memory block 6 contains an eight-bit register R and an adder. The first input of memory block 6, which is connected to the first output of the second memory block 5, receives numbers from the shift register of block 5. These numbers go to the first input of the adder of block 5, the second input of which receives a number from register R. The second input of the third memory block 6 is connected to the second output of the switch 9.

Under the action of the clock pulse coming from the second output of the switch 9, the input number is summed with the number stored in the register R of the third memory block 6 (with the loss of high-order bits when the sum overflows), and the sum is written into the same register with the same number being erased. The output number of the third memory block is used to generate a password (block 14). The third input of the third memory block 6 is connected to the first output of the reset control unit 8. At this input, the register R is set to zero.

The equality block 7 contains two equality schemes. The first input of equality block 7 is connected to the second output of the second memory block 5. The second input of equality block 7 is connected to the output of the fourth memory block 10, the third input is with the output of the response transformer without taking into account the order of input of numbers 13, the fourth and fifth inputs are inverse and direct the outputs, respectively, of the trigger D of the block of operating modes 4. The first input of block 7 receives a number from the shift register of memory block 5 (job code). It is served on both equality schemes (in block 7). The first circuit compares this number with the number received from the output of the fourth memory block 10, the second circuit compares the same number with the number received from the output of the response transformer without taking into account the order of input of the numbers 13. The comparison results go to the output of the equality block 7. Choosing the equality scheme for this is determined by the state of the trigger D block of operating modes 4.

The reset control unit 8 is designed to generate signals when the “Private reset” and “General reset” keys are pressed. When the “General reset” key is pressed, the signal arrives from the fourth output of unit 1 to the second input of the reset control unit 8 and passes to both outputs of this unit. When you press the "Private reset" key, the signal comes from the fifth output of block 1 to the first input of block 8 and passes only to its second output.

Switch 9 contains two triggers and a logic circuit. This switch distributes the input pulses to its outputs. The first input of the switch 9 is connected to the second output of the reset control unit 8. At this input, the triggers of the switch are set to zero. The second input of the switch 9 is connected to the output of the repeat control unit 11, which controls the repetition of response characters. If repetitions are prohibited, then the clock pulses arriving at the third input of the switch 9 from the eighth output of the operating mode block 4, if the same button is pressed again by the user response input unit 1, do not go to the first output of the switch 9. If the repetitions are allowed, then the first two pulses pass only to the second output of the switch 9, and all the rest - only to the first.

The fourth memory block 10 contains the actual storage device (memory) and the address register. The memory can be of various capacities. For definiteness, we assume that it is 4096 bytes. Then the memory address will be a twelve-digit binary number. The address consists of two parts. The first part is formed by an eight-digit number taken from the output of the memory. The second part consists of four binary characters. This four-digit number goes to the third input of the fourth memory block 10 from the output of the code converter block 3. The second input of the fourth memory block 10 is connected to the second output of the reset control unit 8. At the second input, the address register of the fourth memory block 10 is set to zero. The first input of block 10 is connected to the first output of the switch 9, from which the clock pulses are supplied. Under the action of each clock pulse, the output of the fourth memory block 10 receives an eight-digit binary number in parallel form, taken from the output of the memory of block 10. This number is fed to the second input of block 7, where it is compared with the job code received at input 1 from output 2 of the second block 5, and the comparison results are sent to the seventh input of the password generator 14 and to the ninth input of the indicator block 15, where the message “Correct” or “Wrong” is displayed. The fourth input of the memory unit 10 is designed to connect to a communication unit with a USB 19. On this input, you can change the contents of the memory of the fourth memory unit 10.

The repeat control unit 11 contains 16 triggers. Four-digit binary numbers from the output of code converter 3 are received at the second input of this block. Each of them is associated with one of 16 triggers. If all triggers are in zero states, then all input numbers are operational, that is, they participate in the further operation of the device. If these or other triggers are transferred to a single state, then the corresponding numbers become inoperative, that is, the result of evaluating the answers will not depend on them. The third input of the repeat control unit 11, in which all the triggers are set to zero, is connected to the second output of the reset control unit 8. The first input of the unit 11, to which the clock pulses are fed, is connected to the first output of the switch 9. The fourth input of the block 11 is connected to the fifth output block of operating modes 4. If the trigger C of the block of operating modes 4 is in the zero state, then a signal is received at the second input of switch 9 that every pulse coming to its third should pass to the first output of this switch nth input from the eighth output of the operating mode block 4. If the trigger C of the operating mode block 4 is set to a single state, then by repeated pressing of a key of the input response input unit of the user 1, the output signal of the repeat control unit 11 prohibits passage to the first output of the switch 9 clock pulses arriving at its third input from the eighth output of the operating mode block. Suppose that the binary number 0010 is received at the second input of the repeat control unit 11. Then, at the output of the repeat control unit 11, the enable signal will be on. If, on the second input of block 11, the same number 0010 is sent again, this time there will be a inhibit signal at the output of block 11. Thus, when a repeated code is supplied to the second input of the repeat control unit 11, the sync pulse does not pass to the first output of the switch 9. As a result of this, pressing the same key again will not change the result of the operation of the entire device.

The fifth memory block 12 contains a storage device, which stores secret codes necessary for generating a password.

Secret codes can be recorded in the fifth memory block 12 from the USB via the seventh input connected to the third output of the communication unit with the USB 19. The storage capacity can be any. For example, it may be the same as the storage capacity of the fourth memory block 10 - 4096 bytes. In the fifth memory block, in addition to the memory, there is an input (address) register, and at the output there is an output register. The input register is a twelve-digit shift register. At the first input of block 12, a four-digit number from the output of the code converter 3 is written into this register. This number occupies four triggers of the input register. Under the action of the clock pulse supplied to the sixth input of the fifth memory block 12, the first number is shifted simultaneously by four digits, and a new number is written in its place. The output register is a twenty-four-digit shift register that shifts the number under the influence of each clock pulse by eight digits while recording a new eight-digit number in place of the previous one. At the second input of the fifth memory block 12, which is connected to the first output of the reset control unit 8, the input and output registers are set to zero. The clock pulses arrive at the sixth input of block 12 from the second output of the input block of the response of user 1. But not every one of them goes to the sync inputs of the input and output registers of block 12. These registers can only work if triggers A and B of the operating mode block 4 with which the third and fourth inputs of block 12 are connected are set to a single state, and also if a high voltage level is supplied from the first output of the indicator block 15 to the fifth input of block 12. The seventh input of the fifth memory block 12 is designed to be connected to a computer through a communication unit with a USB (through it the information of the storage device is changed).

The response converter without taking into account order 13 contains an adder and an eight-bit trigger register. The first input of the converter 13 is connected to the output of the code converter 3, from which a four-digit binary number is supplied. Before feeding it to the first input of the adder, it is converted to an eight-digit binary number by writing zeros between its digits. For example, the number 0110 is converted to the number 00010100, the number 1011 to the number 001000101, etc. An eight-digit binary number is fed to the second adder input from the register output. When applying pulses to the third input of the response converter without taking into account order 13, the arithmetic sum of the numbers (modulo 256) accumulated at the first input of converter 13 is accumulated in the register. This sum goes to the third input of equality block 7 and to the third input of password generator 14. Second input the response converter without taking into account order 13 is connected to the second output of the reset control unit 8. At this input, the register of the converter 13 is set to zero.

The password generator 14, shown in FIG. 2 as separate blocks, contains a first logical element And 21, a counter 22, a decoder 23, a register 24 of sixteen triggers designated D0 - D15, an adder 25, a trigger 26, a second logical element And 27, and firmware module 28. The password is generated by summing three numbers. The first number goes to the first input of the password generator 14 from the output of the third memory block 6. The second number goes to the second input of the password generator 14 from the output of the fifth memory block 12. The third number goes to the input 3 of block 14 from the output of the response converter without taking into account order 13. These three numbers arrive at the inputs of the adder 25. The result of adding three numbers is supplied to the firmware module 28. The second term, coming to the firmware module 28, is removed from register 24. This register stores dichotomous estimates of responses to individual job interviews. Since register 24 contains 16 triggers, a task can also have no more than 16 questions. When the “Control” key is pressed, a rectangular impulse is received from the third output of the response response input unit of user 1 to the fourth input of password generator 14. It passes through the And 21 element to the summing input of the counter 22, to the trigger input 26 of the trigger and to the input of the And 27 element. Under the influence of this pulse, the number in the counter 22 increases by one and the trigger 26 goes into a single state, which locks the And 21 element. Secondary pressing the “Control” key does not make any changes to the device. If a high voltage level is supplied from the output of the equality unit 7 to the seventh input of the password generator 14, which corresponds to the answer “Correct”, then the corresponding trigger of the register 24 goes into a single state. To answer the second question, you must press the "Private reset" key of the response unit for user response 1. In this case, the low voltage level is applied to the sixth input of trigger 26 from the second output of the reset control unit 8, that is, to the zero input of trigger 26 its in a zero state. After entering the task code and answering one question, the decoder 23 supplies a high voltage level to a single input of the next trigger of register 24 and, if the answer was correct, then under the action of the "Control" key of the response response input unit of user 1, this trigger goes into a single state. And so on. If the task had 16 questions and all the questions were answered correctly, then all the triggers of register 24 will be in a single state. Password generator 14 goes to zero if you press the "General reset" key of the response response input unit of student 1, while the low voltage level will come from the first output of reset control unit 8 to the fifth input of password generator 14 and from the second output of block 8 to the sixth password generator input 14. Password generator 14 has four outputs. Information from the first output in parallel goes to the eighth input of the indicator block 15, from the second output, the number from the register 24 goes to the seventh input of the block 15. All outputs of the decoder 23 are connected in parallel to the tenth input of the block 15. From the fourth output of the password generator 14 to the eleventh the input of the indicator block 15 is the state of the trigger 26. In addition, the ninth input of the block 14, that is, the firmware module 28, the information comes from the output of the response transducer taking into account lowercase and capital letters 16, and the ninth and eighth inputs information comes from the second output of the arithmetic simulator 17 and from the second output of the communication unit with the USB 19, with which information is transmitted from the computer to the firmware module 28 to change the password generation algorithm.

The block of indicators 15 contains three groups of indicators. The first group consists of two LEDs "Correct" and "Wrong." They light up only if a high voltage level is applied to the sixth input of block 15 from the second output of the block of operating modes 4. The ninth input of the block of indicators 15 is connected to the output of the block of equality 7. The signal coming from the output of block 7 is stored in block 15 using a trigger that controls the indicators "Correct" - "Wrong." In the zero state, this trigger is translated by a signal coming from the first output of block 8 to the third input of the indicator block 15. If the answer is correct, the LED with the inscription “Correct” is on. If the answer is incorrect, the LED that says “Wrong” lights up. The second group of indicators is a block consisting of 16 indicators and 16 logic circuits, the corresponding indicator is connected to the output of each of them. If the device operates in a dichotomous response assessment mode, these 16 indicators do not light. They work only if the task consists of several questions, that is, when a high voltage level is applied to the fourth input of the indicator block 15 from the first output of the mode block 4. While the code and answer are being dialed, a high level is maintained at the eleventh input of the indicator block 15 voltage coming from the inverted output of trigger 26 of password generator 14. One of the indicators blinks. Which one depends on the state of the counter 22 of the password generator 14. If the counter 22 is in the zero state, then a high voltage level is maintained at its zero output, and the “0” indicator flashes. After pressing the “Control” key of the student’s response actions input unit 1, the indicators do not light. After pressing the “Private reset” key, the next indicator lights up, inviting you to enter the task code and the answer to the corresponding question. If, after pressing the "Control" key, press the "Password" key of the response response input unit of student 1, a rectangular pulse from the sixth output of block 1 is received at the second input of the indicator block 15. Two cases are possible here. If the external control mode is set in combination with self-control (Table 2), then from the first and fourth outputs of the operating mode block 4, high voltage levels are applied to the fourth and fifth inputs of the indicator block 15, and the indicators show the numbers of those questions for which the correct answers are given . If the external control mode without self-control is set, then none of the indicators of the second group is on. The third group of indicators of block 15 is implemented as a display. The eighth input of the indicator block 15 from the first output of the password generator 14 receives a binary number, which is converted in block 14 to at least a four-digit hexadecimal number called a password. Since the first input of the indicator block 15 is connected to the third output of the block of operating modes 4, and the fourth input of the block of indicators 15 is connected to the first output of the block of operating modes 4, at A = B = 0, high voltage levels are maintained at the fifth and sixth inputs of block 15, and at its first and fourth inputs are low voltage levels. By pressing the "Password" key of the student response input unit 1, the password digits on the display are lit. If there is a low voltage level at the first output of operating mode block 4, and a high voltage level at the third output, that is, A = 0, B = 1 (A and B, see Fig. 1), then the password digits light up in this case. If A = 1 and B = 0, then the password digits on the display do not light. To light them up, you need to press a few more keys corresponding to the task condition. When they are pressed, the state of the output register of the fifth memory block 12 changes due to the secret codes of the storage device of block 12. After this, when the “Password” key is pressed in the response response input unit of user 1, all the information needed on the keyboard is displayed on the keyboard for visual control produced set. If errors are detected before pressing the “Control” key of the user response input input unit 1, all the collected information can be erased by pressing the “Private reset” key of the user response input input unit 1. The first output of the indicator block 15 is connected to the fifth input of the fifth memory unit 12. Until the first pressing the “Password” key of the student’s response actions input unit 1 the fifth memory unit 12 does not work. The second output of the block of indicators 15 is connected to the fourth input of the block of operating modes 4. After the first pressing of the "Password" key of the block for entering the response actions of the student 1, the clock pulses do not pass through the block of operating modes 4. And in the case when A = B = 1, this happens after the second press of the "Password" key.

The response converter, taking into account lowercase and uppercase letters 16, consists of one trigger W. When trigger W is in the zero state, lowercase and uppercase letters are indistinguishable. When the “Register” key of the user response input unit 1 is pressed from the eighth output of this unit, a high voltage level is supplied to the third input of the unit 16, and a sync pulse passes from the second output of the unit 1 to the second input of the unit 16, which transfers the trigger W to a single state. Reset to the zero state is carried out by the pulse, which from the second output of the reset control unit 8 is supplied to the first input of the block 16 when the “General reset” key of the user response input unit 1 is pressed.

The arithmetic simulator 17 contains a register into which a response is received at the first input from the first output of the response response input unit of user 1. This answer also comes to the arithmetic block, also included in block 17. Transfer to the simulator mode by pressing the "Simulator" button of the user response input block 1. The transfer signal comes from the ninth output of the user response block 1 to the third input of block 17. On the fourth input of block 17 passes clock pulses from the second output of the response input unit of user 1, ensuring the operation of the entire block 17. At the second input of block 17 connected to the second output of the reset control unit 8, etsya simulator translation of arithmetic operations 17 to its original state. In block 17, pairs of numbers are formed. In the same place, the actions specified in the task code are performed on these numbers. In the simulator mode, the first five characters are used (after the sign indicating the operation mode) coming from the first output of the input unit of the response of user 1 to the first input of the arithmetic simulator 17. If the answer is correct, the arithmetic block forms a new pair of numbers. In case of an incorrect answer, the generated pair of numbers does not change, and the message “Wrong” is displayed on the indicator block 15. When all the exercises provided for in the task code are completed correctly, the corresponding information is received from the second output of block 17 to the eighth input of the password generator 14, which are converted into a password by block 14. The signal for permission to issue a password is supplied from the first output of the arithmetic simulator 17 to the thirteenth input of the indicator block 15.

In the sixth memory block 18, the first input records information about the student’s personal data coming from the first output of the response block of the user 1. The recording is performed under the action of clock pulses passing from the second output of the response block of the response of the user 1 to the third input of the sixth memory block 18. After completing the input of personal data from the third output of the keyboard of the input unit of the response of the learner 1 (when the "Control" key is pressed), a high voltage level is applied to the fourth input of the block 18 This is due to the fact that information coming from the first output of the response response input unit of user 1 to the first input of the sixth memory block does not enter block 18. Pressing the “Control” key again is equivalent to the action of the “General reset” key (under which the device returns to its initial state), but with the preservation of information about personal data recorded in the sixth memory unit 18. At the second input, the sixth memory unit 18 is set to its original state the signal from the key "General reset", coming from the fourth output of block 1.

The communication unit with the USB 19 is implemented in software using a microprocessor. This unit performs only interface functions that provide communication with the DRC. Through this block, all the information from the first memory block 2, which is transmitted to the first input of block 19, is copied to the DRC at the first output. Recording is carried out after pressing the “Communication with DRC” button with the signal from the tenth output of the block for the response of user 1 to the second input of the block communication with the USB 19. At the third input of block 19, the personal information about the student from the output of the sixth memory block is copied to the USB. The fourth input of block 19 is designed to transfer information from the DRC to blocks 10, 12 and 14. From the second output of the communication unit with the DRC 19, information can be written on the tenth input to block 14 and thereby change the password generation law, thereby increasing the stability of the encoding system against password forgery. From the third output of the communication unit with the USB 19, you can transfer new information to the fifth memory block (via the seventh input) and change the secret codes stored in it, which also enhances the protection of information about the results of control transmitted using a password. From the fourth output of the communication unit with the DRC, new information can be transmitted to the fourth input of the fourth memory block 10 in order to change the criterion for dichotomous assessment of the response.

Each task given to the student contains a short circuit obtained by converting the answer according to the algorithms implemented by blocks 3, 4, 5, 7-11, 13, 16, 17. The process of finding a short circuit is called encoding the task. The length of the job code can be any and is limited only by the amount of memory used. It may be less than the length of the response code. This ensures the stability of the coding system against attempts to get a good estimate in another way, without correctly solving all the tasks of the task, since the conversion of the response into code is unambiguous, and the reverse conversion of code into answer is ambiguous, that is, in the vast majority of cases it is impossible to restore the correct answer from the code . The user who has completed the encoded task and wants to check whether the answer obtained from him is correct, first enters the task code into the device, and then dials the response character by character. By the state of the indicators of the indicator block 15, the user determines the correctness of the entered answer. Under one code, several questions (tasks, exercises) can be presented. In this case, the user also first dials the task code, and then enters all the answers in a row in the order of the tasks. The number of tasks under one code is not limited.

Example 1. Assume that the task consists of one question: “(ACV). What is the capital of Norway ?, where ACV is the job code.

We press the computer key corresponding to the fourth output “General reset” of the user response input unit 1, from which a high voltage level is supplied to the second input of the reset control unit 8. A low voltage level will appear on both outputs of the unit 8. The following will go to the zero state: operating mode block 4, second memory block 5, third memory block 6, switch 9, fourth memory block 10, repeat control block 11, fifth memory block 12, response converter without taking into account order 13, password generator 14, block indicators 15, the response converter, taking into account lowercase and uppercase letters 16 and the arithmetic simulator 17. Press "A". In the register, consisting of triggers A, B, C and D of the block of operating modes 4 (figure 2), the number 0000 is written. The letter “A” will appear on the display of the indicator block 15. According to Table 2 of the operating modes, this means that the order of input of elements is taken into account, repetitions are taken into account, and the answer will be evaluated dichotomously in the “Correct” - “Wrong” system. In the future, the state of the block of operating modes 4 will not change. Enter the letter "C". According to Table 1, the letter “C” at the output of the code converter 3 corresponds to a five-digit code 00111. Of these five characters, four are the lowest. Therefore, the code 0111 goes to the first input of the second memory block 5, to the third input of the fourth memory block 10, to the second input of the repeat control block 11, to the first input of the fifth memory block 12 and to the first input of the response transformer, without regard to order 13. To the first input of the block operating modes 4, the entire five-digit code is supplied. The clock from the second output of the input unit of the response of the user 1 passes to the second input of the first memory block 2, to the second input of the operating mode block 4, to the sixth input of the fifth memory block 12, to the second input of block 16, to the fourth input of block 17 and to the third input block 18. From the eighth output of the block of operating modes 4, the pulse will go to the third input of the switch 9, and from its second output to the second inputs of the second block of memory 5 and the third block of memory 6. Thus, code 0111 is written to the register of the second block of memory 5 , and on the display of the indicator block 15 pr The letter “C” will appear instead of the letter “A”. The state of the third memory block 6 will not change. Enter the letter "B". After pressing the “B” key, the letter “B” will appear on the display of the block 15 to the right of the letter “C”, and the number 01110010 will be written in the register of the third memory block 6. The job code is entered.

Now we type the answer OSLO. We press on the computer the key corresponding to the letter O. Its binary code 1110 from the output of code converter 3 to the second memory block 5 and the third memory block 6 will not be overwritten. This code will change the state of the fourth memory block 10, the repeat control unit 11, and the response converter without taking into account order 13. Changes in the repeat control unit 11 are not important, since a high voltage level is maintained at its output due to the set operating mode of the unit 4. Not important and changes in the response transformer without taking into account the order 13, since the control is carried out taking into account the order of the entered characters. The entire memory of the storage device of the fourth memory block 10 is filled with eight-digit binary numbers. After filling it, the fourth memory block 10 turns into a response transformer. Assume that the storage device of block 10 is in some way full. At the moment of feeding code 1110 (letter code "O") to its third input, the number 10,000,000 was in the output register of block 10. Therefore, the full address applied to the input register of the storage device of block 10 is 000000001110. Suppose that the fourth memory block is output 10 there appeared, for example, an eight-digit number corresponding to the letter “a”. By applying a sync pulse, this number will be rewritten in the input register of block 10. A new address will be received at the input of the storage device if you press the key corresponding to the next letter of the answer being entered, that is, the letter “C”. The clock will overwrite the new number in the input register of block 10. And so on. The entered word OSLO will appear on the display to the right of the entered “ACV” code. If, after entering the entire response, the output of block 10 turns out to be a number that matches the job code stored in the register of the second memory block 5, then the answer is correct. At the output of equality block 7, there is a high voltage level. It is fed to the ninth input of the indicator block 15. By pressing the “Control” key of the computer corresponding to the third output of the user response input block 1, the “Correct” indicator lights up. If the number corresponding to the answer does not match the task code, then the “Wrong” indicator will light up by pressing the “Control” key.

The considered example can be encoded in the mode of indifference order. This means that the first character of the task code must be B or P (Table 1). Assume that the job code is in the form of BDP. In this case, after entering codes 1110, 0010, 1011, 1110 (OSLO according to Table 1), the number 11110001 appears in the register of the response converter without taking into account order 13. The same number is stored in the second memory block 5. This time, a high voltage level is maintained at the sixth output of the block of operating modes 4 (D = 1), therefore, in the block of equality 7, its output receives the result of comparing numbers from the second block of memory 5, where the short circuit is located, and the response converter without taking into account order 13. This mode is characterized by the fact that there are twelve answer options that may be Obtain by all kinds of permutations of the letters in the word Oslo. This mode is especially convenient when the answer is some expression, for example, ab + cd, or a set of numbers whose sequence does not matter, for example, the roots of the quadratic equation.

If the first is the character of the task code B or C, then the mode is set when each entered character is taken into account only once, and the order matters. This is code 0010 (Table 1). If you want to encode the answer in the mode of indifference of the order and without taking into account the repetitions, then you must first select the sign “G” or “T”, which corresponds to the UN code (Table 1). This can be illustrated by another example task:

Example 2. (TMP). Specify conifers in the list below.

(256) spruce, (187) poplar, (257) birch, (817) bird cherry, (345) fir, (123) larch, (739) aspen, (349) alder, (146) thuja, (627) mountain ash.

In this list, each of the alternatives is assigned a code. The student acts as follows. Gets the job code. The letter T code sets the mode of indifference of the order and the exclusion of repetitions. After entering the letters M and P in the register of the second memory block 5, the number 1101 1111 appears. It is compared with the output number of the response transformer without taking into account order 13. To get the “Correct” score, you need to choose alternatives whose codes are summed in the transformer of the answer without accounting for about 13 will give the same number 11011111. This will happen when the student chooses at least three of the alternatives: spruce, fir, thuja, larch (but you can choose all). In all cases, the sum of the corresponding codes in the response transformer without taking into account order 13 will be 11011111, since codes 0101, 0110, 0111, 1000, 1001, 1010 will be summed up each time, participating in this operation only once.

The mode codes 0100, 0101, 0110, 0111 correspond to the case when self-monitoring is carried out not according to the indicators “Correct” - “Wrong”, but according to passwords. Having received such a task, the student, after entering the answer, presses the "Password" key. If the sequence of illuminated password signs matches the given one, then the answer is recognized as true.

In cases where the answer is a sequence of certain characters, they can be separated by commas, a semicolon, or not separated by anything. In such cases, it is convenient to use dot codes. An example is the code (A.MK). If, after entering the letter A, press the key on the computer corresponding to the seventh output of the user response input unit 1 “Point”, then all the characters indicated in the third column of Table 1 with codes 11001, 11010, 11011, 11100, 11101, 11110, 11111, will be "indifferent." The corresponding keys can be pressed, but you can not press. In the absence of a point in the task code, all service signs become as mandatory as all others.

The considered mode with a point can always be applied where service signs form the multivariance (ambiguity) of the response input. For example, the product of two or more quantities can be written using multiplication signs, points and no signs. To eliminate this ambiguity, it is enough to encode the task in the mode of indifference of service signs. Then, when entering the answer, the user can enter the character that he considers necessary, and the result will be the same in all cases. The same goes for brackets. For example, as a result of the simplification of some mathematical expression, it may turn out, say (a + c), which can be written without parentheses.

You can use a computer to encode tasks, but the proposed device allows encoding without a computer. To do this, it is enough to enter any task code in it, for which only the first character will be quite certain, since the operation mode of the device is always known in advance. Then enter the answer. The desired task code will be obtained at the output of the fourth memory block 10. The desired code can be obtained in alphanumeric form if you connect the output of block 10 to the block of indicators 15 (this relationship is not shown in Fig. 1).

From the above it follows that the claimed device solves the tasks and, compared with the prototype, has wider logical and didactic capabilities. These features are as follows:

Firstly, due to the introduction of new blocks, new connections between blocks, it is possible to store all entered information in the DRC with the subsequent transfer of information to a computer, which allows classes in any room, including those not equipped with computers. It does not require the presence of any kind of power network, since the DCU and the claimed device operate from autonomous power sources.

Secondly, thanks to the block of the simulator of arithmetic operations, it is possible to use the “non-standard” technology for performing arithmetic exercises (operations of addition, multiplication, subtraction and division). External control of these operations is carried out due to the advanced capabilities of the password generator.

Thirdly, when using the inventive device in the classroom for external control, students are identified using the inventive device itself.

Fourthly, to control the execution of exercises where it is required to distinguish between lowercase and uppercase letters, an appropriate block is provided.

Fifth, thanks to the expanded symbolism of the claimed device can be used in any non-Russian schools.

Sixth, in the inventive device, a built-in rather than a remote keyboard is used.

All this extends the logical and didactic capabilities of the device and its operational characteristics.
