St. No. 723646, a training device is known comprising a response input unit associated with a response comparison unit and a memory unit connected to a playback unit that is connected to the registration unit, the address comparison unit, the address register, the response comparison unit and the attribute determination unit connected to an address comparison unit, a control unit and a response comparison unit associated with a control unit that is connected to an address registration unit and an address register connected to a memory unit and an address comparison unit whose output is oh connected to memory block 1.

This device allows you to individually train and control the operators of various production plants and control systems, to implement a large number of algorithms for the operation of ij operators.

However, when training the operators on this device, it is not fully achieved that the operator’s actions on the real object 5 and on this device are real object processes require coordinated actions of several operators. (students).

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

This goal is achieved by introducing a series-connected switch, a mode locking unit, and an additional comparison unit connected to the feature recognition unit, the control unit, and the playback unit connected to the operation mode locking unit 0, which is connected to the control unit and the unit. address comparison, the switch is connected to the memory unit.

FIG. 1 shows the structure of the device 5; in fig. 2 - four types of codes with a schematic representation of a playback unit; in fig. 3 - functional block diagram of the mode of operation and an additional unit of comparison.

The training device (Fig. 1) contains a switch 1 and remote controls 2 learners in which the response input unit 3 is connected with the response comparison unit 4 and the memory unit 5 connected to the playback unit b, which is connected to the response comparison unit 4, the registration unit 7 , the address comparison unit 8, the address register 9, the operation mode latching unit 10, the comparison unit 11 and the attribute detection unit 12 associated with the control unit 13, the comparison unit 11, the address comparison unit 8 and the response comparison unit 4 connected to the control unit 13 related with register 7 and a mode locking block 10 connected to the inputs of switch 1 and a comparison block 11 connected to a control block 13 connected to address register 9 connected to memory block 5 and an address comparison block 8 associated with a lock block operating modes 10 and the memory unit 5, the input of which is connected to the switch 1, associated with the inputs of the unit 10.

Switch 1 connects block 10 of each console 2 with blocks 10 and memory blocks 5 of all other consoles 2. Answers input block 3 consists of response input organs, a decoder, response memory triggers, and a tape drive start relay (not shown). The memory block 5 contains a data carrier on a film with information frames and control codes and a reversible tape drive mechanism, the playback unit 6 consists of photovoltaic photoelectric amplifiers of the same type that convert photo pulses into electrical pulses and amplify them. The operating mode locking unit 10 contains memory elements for storing the status codes of all the other consoles 2, valves for recording the new state code of this console 2 into the blocks 10 of the other consoles 2, and connection elements of the tape mechanisms in the other consoles 2 (not shown in the drawings ). The device status code recorded in block 10 of this console 2 is determined by the set of status codes of all other consoles 2. Comparison unit 11 compares the status code of the device with the possible status codes printed on the film.

In the proposed device, the programs have four types of codes 14-17 with different functions in controlling the operation of the device.

Type 14 codes contain a possible response code 18, intended for comparison with a response code, bit. A mandatory comparison 19, which is necessary for an unconditional comparison with a answer code, bit. Wrong 20, intended for entering one penalty point in the registration unit 7, and the hallmark 21 is used for identifying type 14 codes by block 12. Distinguishing feature 21 contains such a combination of codes in its bits that is prohibited for other types of codes (for example, the 3 rd bit from the bottom is light and the 2 nd is dark).

Type 15 codes contain a code of a possible state of the device 22 and a distinctive sign 23 intended to identify type 15 codes by the unit 12 (the 3rd discharge bit is dark, the 2nd light).

Type 16 codes contain the address of the next frame 24, by which the next frame should be searched, the resolution of changing the state of the device 25, the state changing code 26 and the sign 27, which identifies type 16 codes by block 12 (2nd and 3rd th bit below dark).

Type 17 codes contain an address (code of the desired frame 28, which is a binary frame number and intended to be compared with the address of the next frame 24, the launch code of the tape-and-pinch mechanisms 29 in other consoles 2 and distinctive sign 30, designed to identify type 17 codes by block 12 ( The 2nd and 3rd bits below are light).

In codes of all types, there is one service bit Marker 31, intended to form a resolving signal for reading the code and is necessary for the information not to be read from the frames during the motion of the film. The marker must be located below (or above) the frame level, and the signal from the output of the marker phatoelectric amplifier 32 of the playback unit b is fed to the remaining photoelectric amplifiers 33-41 as a resolution.

The training device works in the following way (Fig. 1).

At one of the consoles 2, after entering the response, unit 3 delivers the response code to the response comparison unit 4 and the tape triggering signal in the memory unit 5 of this console. During the motion of the film, the control codes pass by the photo sensors of the playback unit 6, are read, amplified, and fed to the blocks 4,712. Based on the response code and the codes read from the film, it searches for the desired frame of this console 2.

In the initial state, the remote control 2 responds only to type 14 codes. The response code goes to block 4, which also receives signals from the bits of the playback unit of photoelectric amplifiers 33-35, which read the codes of possible answers 18 and bit. Comparison of 19 In addition, a blocking signal is received from block 4 from the block for detecting signs 12 about reading type 14 codes. If there is a comparison (or a mandatory comparison) of the response code of this console 2 with a code of a possible answer, block 4 outputs a comparison signal to the control unit 13, In the block is defined Signs 12 receives signals from the bits of the playback unit 6, which are occupied by distinctive features, and from block 12, the resolving signals about the presence of a code type are received into the response comparison block 4, if the read code is type 14, the comparison block 11, if Type 15 code, into control unit 13, if the code is of type 16, and into address comparison block 8, if it is type 17. The control unit 13, using a signal from block 4, memorizes the presence of a comparison of the response code and the possible response code and gives a short-term error recording signal the recording unit 7, and if the 20th discharge compared code type encoded signal 14 is wrong, from which unit B enters the registration unit 7, the two signals in coincidence unit 7 detects and indicates an error. After the signal is stored comparing the possible response code with the response code by the control unit 13, this remote control 2 only responds to the type 15 code. When reading the type code 15, the attribute detecting unit 12 delivers an enabling signal to the comparison unit 11, which device 22, coming from the reproducing unit b in block 11, is compared with the state code of the simulator arriving from block 10 to block 11. When each of these codes is compared to block 11, a comparison signal is sent to the control unit 13. To decrease the number of A code of type 15 provides a device 22 for an unconditional comparison of the state code of the simulator with the code of a possible state if the code is all units. The control unit 13 memorizes the presence of a comparison, and further, the remote control 2 responds only to type 16 codes. The first type 16 code causes a signal from block 12 to block 13, which generates an enable signal to block 10 to change the contents of the latter in other consoles 2 and the signal to write the address of the next frame to the address register 9. The address of the next frame 24 contained in the type 16 code is transferred from block 6 to the address register 9, written into it, and stored for the next frame search time. The address of the next frame contains a bit of the direction of motion of the film Reverse, and if the frame of interest is in the direction opposite to the original (direct) direction of motion of the film, then the address register 9 sends a Reverse signal to the memory block 5 where the direction of motion of the film changes to the opposite. According to the signal from amplifier 36, corresponding to the resolution of changing the state of the device 25, type 16, coming from block 6 to block 10 and the presence of a signal from block 13 to block 10, the latter changes the content similar to other consoles 2. In this case, the status change code of the device 26 comes from amplifiers 37-39 of block 6 to block 10, and from there, via switch 1, to the corresponding memory bits in blocks 10 and other consoles 2. Address comparison block 8 performs bitwise comparison of address the next frame coming from the register address a 9 and a frame code 28 coming from amplifiers 33 and 34 of playback unit 6 in the presence of an enabling signal from feature detection unit 12 on the presence of type code 17. When compared by block 8, a signal is output to the PSM-5 block. If a bitwise comparison of the address of the next frame with the frame code has occurred, block 8 also sends a signal to block 10, according to which the startup code of the tape-carrying mechanisms 29 from amplifiers 35-39 of block b goes through block 10 to switch 1, which, depending on code 29 launches tape mechanisms in other consoles 2. Block 10 and block 11 (Fig. 3) contain memory elements (bits) 42 4, logical equivalence elements 45, 46, 47, elements AND 48-57, elements OR 58-60 . The memory of block 10 of this console wakes the device status code and stops, for example, from three bits 2, which correspond to one of the remote controls 2 devices, bits 3 corresponding to the other console, etc., as well as from bits 44 corresponding to the last of the bullets 2. If the student on one of the remotes changed the state of the device, the status change code from block 10 of this remote control will be written into the corresponding bits of the block 0 of this remote control 2. Memory of the remote control

2 stores in this way the status codes of all consoles 2 except this one,

The equivalence elements 45 compare the state code of the first console 2 with the code contained in code 22 and coming from amplifiers 37-39 of block b. When bitwise comparing, the signal from the AND 48 element through the OR 58 element goes to the AND 51 element. If units are recorded on the memory elements 42, the signal for the comparison from the output of the AND 55 element goes to the OR 58 element, which translates the comparison signal to the element And 51.

In a similar way, the status code of other remotes 2 is compared with the corresponding code bits of the possible state of the device 22, With bitwise comparison (or optional) of the possible state of the device 22 with the state code recorded in the memory of unit 10, and the presence of the enabling signal from the block 12 from the output of the element And 51, the comparison signal enters the control unit 13.

The signal from amplifier 36 corresponding to the encoded bit 25 of type 16 code, and the signal from block 13, which go to block 10 on AND 53, allowing the output from And 53 to go to And 54 elements. The status change code of device 26 from amplifiers 37-39 enters the elements And 54 of the block 10 and from the elements 54 And through the switch 1 - into the block 10 of other consoles for writing code 26 in the memory bits 2 corresponding to this console.

The startup code of the tape mechanisms 29 from the amplifiers 35-39 of block 6 goes to the elements And 52 and, if there is an enabling signal from block 8, the code 29 goes to the switch 1, which sends a signal to start the tape mechanisms in the console

2 corresponding to code 29 (for example, the first coded bit of code 29 from below starts the tape drive mechanism of one of the console 2, the second from the bottom of the other console 2, etc.). The application of the proposed device allows the selection of the learning algorithm of a student to perform depending on his answers and on the current state of the device. This, in

turn allows you to train

students' mutually agreed actions with a constantly changing state of the object displayed on the frames with educational information, which significantly improves the quality of education. In addition, the device makes it possible to simplify the programming procedure, since there are no restrictions on the location of the desired frame. Functional enhancement

the capabilities of the device are produced by its slight complication.
