Abstract

The invention relates to automation and computer technology and can be used in the training and control of knowledge of operators of various industries, where it is necessary to follow the sequence of operations. The purpose of the invention is to expand the didactic capabilities of the device, which contains the block 1 of the memory of the response element, the block 2 of the comparison, the block 3 of the memory of the operation and the block 4 of the presentation of the result. These blocks form a node 5 to perform a single operation of the simulator. The number of nodes 5 in the simulator corresponds to the number of operations in the process under study. The outputs of each node 5 are connected to the corresponding inputs of the subsequent similar block. The outputs of node 5 are the direct and inverse outputs of block 3. The inverse input of node 5 is the input of block 2. The direct input is the input of block 3. The simulator also has an error counting unit and an audible alarm unit. These blocks are connected via a bus to the outputs of blocks 5. The invention allows the next exercise operation to be performed only after the previous operation. 2 Il.

The invention relates to automation and computing, can be used to train and control the knowledge of operators of various industries, where it is necessary to follow the sequence of various operations, is designed to work out the sequence of these operations and can be used to prepare and control the knowledge of operators of the chemical and petrochemical industry .

The aim of the invention is to expand the didactic capabilities of the device while ensuring the development of the sequence of operations, in which each subsequent operation is possible only when the previous one has been completed with the operator's independent training.

Fig „1 shows a diagram of the device; figure 2 - block diagram of the simulator.

The device contains a response element memory block 1, a comparison block 2, an operation memory block 3, a result presentation block 1, included in the execution unit 5 of a single operation of the simulator also containing a generator block 6, units 7 and 8 of the installation initial and final state, sound alarm unit 9, error recording unit 10, interface unit 11, computer 12.

The simulator using this device works as follows.

When the sensor E3 of the unit 7 is touched, the impulse appears at its output, which sets the circuit to the initial state, i.e. the memory elements of all nodes 5 are reset. When the E1 sensor touches the first node 5, the capacity of the input of block 1 increases and the pulses to the C input of the trigger of block 1 are delayed relative to the pulses on the D input. At the forward trigger output, 1 appears, and at the inverse output, 0m, which goes to the input signaling bus. The one-shot of block 9 is triggered, and a sound signal is issued confirming the input of the operation C of the forward output of the trigger of block 1, a pulse arrives at the C input of the trigger of block 3. Since this D input

the trigger of the first node 5 is constantly high logic level, the trigger assumes state 1 and the display switches accordingly. Block 11 receives a high logic level from the direct output of the first node 5. With block 11 information about the implementation of the first operation enters the computer 12.

When the sensor Eg of the second node 5 is touched, similarly to the first case, a beep will be performed confirming the operation input. From the output of block 1, a pulse arrives at the C input of the trigger of block 3. Since the D input of this trigger receives a high logic level from the direct output of the previous one node 5, the trigger changes its state by 1 m, while the input of block 2 receives a low logic level from the inverse output of the previous node 5 blocking the appearance of an error signal. In the same way as when performing the first operation, the corresponding switching of the display takes place and, through block 11, the computer 12 receives information on the performance of the second operation. Thus, without disrupting the sequence, it is possible to transfer all triggers of blocks 3 to state 1, i.e. If the sequence is disrupted, for example, after setting the device to the initial state, the sensor does not touch the first node 5, but any other, then a low logic level appears on the D input of the trigger block 3 of the corresponding node 5 the previous node 5, and on the impulse arriving at the C input of this trigger, the trigger of its state does not change, i.e. remains in the state O, the indication is not switched. In addition, at the input of block 2 there is a high logic level, coming from the inverse output of the previous node 5, and at the moment the sensor touches another input of block 2 also turns 1, as a result of which output of block 2 appears level O1,1 which It enters the error signal bus, starts the one-shot of block 9, and the corresponding signal is generated, which signals an error. The low logic level signal also triggers the one-shot of block 10, and the state of single-decimal counters changes by one.

The proposed device provides testing of the sequence of operations in the training mode, i.e. after performing the next operation, information on the subsequent operation to be performed is displayed on the computer display screen. Through the use of sensory input, the reliability, durability and usability of the device are increased. In the knowledge control mode, the degree of training of a student by the number of errors made in performing successive operations is assessed.

If an error is made, the audio signal draws the attention of the student to an error, which makes it impossible to continue the sequence of operations until the correct answer is entered, does not allow the student to skip any operation in the sequence of operations and causes him to look for the correct option for entering operations, contributes to better assimilation of the sequence of operations.
