In addition, this functional diagram shows the unit 6 for monitoring and controlling the sequence of learning operations, made in the form of a decoder, a logical circuit and a counting device with a logic circuit AND at the input, with the first and second inputs of the decoder serving as the first and second inputs of the control unit and control the sequence of learning operations, the third input of the decoder is connected to the output of the counting device, the output of the decoder is connected to the first input of the circuit AND of the counting device, the second input of this circuit And connected to the output of the logic circuit is NOT, the input of which

The functional diagram (Fig. 02) shows the error signaling control unit 7, made in the form of a decoder, the first, second and third inputs of which serve respectively the inputs of the error signaling control unit 7, and the error signaling device 8 in the form of a low-frequency generator and a signal lamp.

The work of the proposed simulator is as follows

In block 5, the tasks of the learning algorithm include a switch, for example, 5c, 2, defining the selected learning algorithm. If the controls of the control unit 1 are in a position that corresponds to the beginning of the working out of this predetermined learning algorithm, the combination of signals from the switch 5.2 and from the controls control unit 1, enters the inputs of the decoder of control and control unit 6 of the sequence of operations-0. The signal from the output of this decoder arrives at the 1st input of the AND circuit, at the 2nd input of which p is present. Allowing signal From the circuit output AND, the signal is output to the counting device, which passes on this signal to the next state. The signal about this state of the counting device falls on the third input of the information display unit 3. This signal, in combination with the signals arriving at the first and second inputs of the specified block from the control unit 1 and the learning algorithm task block 5, generates a signal at the output of the decoder of the information display unit 3 that includes the corresponding signal devices (for example, lamps 301,302), signaling On the need to perform certain learning operations. If the operation is performed correctly, in the control unit 1, the corresponding device is turned on (for example, the limit switch 1.2), which gives a signal Lock 3 display information. Under the action of this signal, the signal lamp is switched on, corresponding to the operation performed.

At the same time, the same signal from block 1 of the control is fed to input I

block 6 of control and management of the sequence of operations, which switches to a new state. If, in accordance with a given learning algorithm, the next operation should be an operation determined by, for example, a 1 „1 switch. then when this switch is turned on, the operation of the simulator will occur as described above. At specified points, the learning operations are performed, which are determined by the corresponding states of the control and control unit 6 of the signal combination received at the inputs of the decoders of the engine simulation unit 2 and the digging simulation unit 4 machines turn on (or turn off) the necessary elements of their blocks0

In case of a wrong learning operation (wrong choice of control, non-observance of specified time intervals and so), the combination of signals input to inputs 1, 2 and 3 of the decoder of the error signaling control unit 7 causes the error signaling unit 8 to exit. At the same time, this signal is fed to the NOT circuit of the control and control unit 6 for the sequence of operations, and the output of the element does NOT lock the AND element associated with the input of the counting unit. The counting unit cannot switch to subsequent states.

In this position, the proposed simulator will remain until the incorrectly switched control of the control unit 1 is returned to its original position. For example, if limit switch 1.N (its closing contact is closed) was mistakenly pressed, then until this limit switch is released, the counting unit will not be able to go to the next state and allow the development of the specified algorithm to continue learning ,, Thus, the learner himself can control the accuracy and quality of his performance of learning operations

When the incorrectly switched switch returns to its original position, the signal is removed from the first input and output of the decoder of the error signal control block 7,

the operation of the error signaling device is terminated. At the same time, the prohibition of the operation of the AND element at the input of the counting block of the control sequence control control block 6 is lifted.

During the subsequent correct execution of operations (taking into account the predetermined sequence of their execution), the devices of the proposed simulator operate in the same way as described.

Thus, with each incorrect switching of the switches of the control unit 1, the training operations are blocked and an error signal is generated.

The use of the device leads to an increase in the effectiveness of training, as it reduces the learning time and the development of automatic skills in the learner and reduces the time spent by the trainer.
