Abstract

The invention relates to automation and is intended to develop practical skills for students in properly fitting the most common plug-in connectors. The aim of the invention is to expand the didactic capabilities of the device. The device contains a task switching unit 1, an electrical connection set unit 2, an EHZf connection control unit 3, an installation input unit 4, an installation time setting unit 5, an installation time control unit 6, a registration and evaluation unit 7, an initial state setting unit 8 and a generator 9 with the circuit compounds described in the formula. Before starting work, the student is issued a task card in which the numbers of the k-th group plug-in connectors are indicated, which he must properly connect. The teacher on the console turns on the power supply of the blocks and dials the specified connector group in block 4 with the help of switches B1- 83. After the students dock all the connectors of the group, an electrical signal is generated at the output of unit 3, which is sent to the task execution recording in block 7. Connectors include one or another indicator of evaluation unit 7 1 Il. Yo - -

The invention relates to automation, in particular to devices for teaching professional skills, and is intended to develop in practical training skills in correctly fitting the most frequently encountered plug connectors of electrical equipment.

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

The drawing shows a diagram of the device.

The device contains a block 1 switching tasks block. 2 sets of electrical connections, block 3 of control of connections, block 4 of input of standards, block 5 of the task of installation time, block 6 of control of the time of installation, block 7 of registration and evaluation, block 8 of the installation of the initial state and generator 9.

The device works as follows.

Before starting work, the student is issued a task card in which the numbers of the plug connectors of the i-th group are indicated, which he must properly connect. After that, the teacher turns on the power of all the units of the device, sets the set frequency of the generator pulses 9 depending on the complexity of the question and thus sets the time interval oi veta to the question posed. Then the teacher dials a given group of circuits with the help of the switches of the block 4, turns on the device and gives the command to begin the docking of the connectors.

During the assignment of the student, the counting pulses of the generator 9 enter the first counter of block 5, the output of which generates a high level of potential 1, and then, with a different frequency, begin to flow to the input of the second counter of block 5 and the first element of the NAND block 6. In the initial state, the first logical element of the NAND unit 6 from the first counter of unit 5 and unit 3 is supplied with a low potential level O and the signals I of the second, third and fourth elements of the NAND unit 6. At the output of the first element NID block 6 there is a signal 1, but he first unit 7 transparency thus extinguished. Similarly, signals 1 are present on the second, third, and fourth elements of the AND-NOT of block 6, while other banners of block 7 are also canceled (AND, AND-NOT elements, counters and banners are not shown).

After the first counter of block 5 counts a certain number of pulses, a 1 signal appears at its output, which is fed to the first logical element of the NAND block 6. If by this time the learner makes all the connectors of the specified group docked, then at the output of the multiplexer block 3 is formed

Signal 1, which is fed to the repeater input and to the inputs of all the elements AND-NOT of block 6, and from the output of the repeater of block G passes to the input of the registration banner of the execution of the task of block 7. When

0 this, at the output of the first NAND element, in block 6, a signal O appears and in block 7 a transparency with a rating of 10 lights up. At the same time, the signal O from the output of the first element of the NAND block b

5 is fed to the input element And block 7. The signal from the output of the latter blocks the generator 9.

If the arrival of signal 1 from the first counter of block 5 does not come with a signal of 1 s

0 of block 3, then at the output of the first element of AND- NOT of block 6, signal 1 is present and the transparency of the block does not light up.

If with the arrival of signal 1 from the second counter of block 5 to the second element NAND

5 of block 6, signal 1 comes from block 3, a signal O appears at the output of the second element AND-NOT of block 6, which leads to the inclusion of the transparency of block 7 and blocking the first element of IS-NOT block 6,

0 excluding the possibility of fire trans- osriia in the batch 6. Simultaneously, the generator 9 is also blocked by a signal from the output of the element AND of the block 7.

Anshishogno the inclusion of the third element AND-NOT in block 6 leads to blocking of the first and second elements of the IS-NOT and the exclusion of the corresponding lights in block 7.

After the assignment is completed, the student disconnects the connectors, and the teacher turns off the power supply. The device is again ready for operation.

5 The invention allows to automatically form an assessment of the skills of trainees according to three parameters: the reliability of the joining of specified groups of connectors, which ensures reliable electrical

0 connection between their counterparts; addressing of dockable connectors (without entanglement) according to the task map, which is ensured by a steady glow of the correctness of

5 task execution; task execution time. In addition, the constructive execution of blocks 1 and 2 corresponds to the actual process of assembling the electrical circuitry, which allows an increase in the accuracy of the assessment of the skills of the trainees.
