The purpose of the invention is to expand the functionality, rasterize the field of application of the device by controlling the lag of the actual time of each operation from planning and operational accounting of the time of lag and space and expanding the informativeness of the device by indicating additional parameters.

FIG. 1 shows the functional scheme of the device; in fig. 2 - comparison unit.

The purpose of the invention is achieved by operatively monitoring the backlog of actual execution of each operation from planned, urgent detection of cases of backwardness and by taking into account the backlog time of operations. 1 hp ff, 2 sludge

the second and second elements are NOT-23 and 24 and the elements are NOT 25 and 26.

The device works as follows.

Before starting, the dispatcher (operator) sets on the first block of 6 switches the divider's divider ratio 2 frequencies equal to the planned target for manufacturing products for the planned working period of time, and on the second block of 9 switches - the time for controlled operations. In the initial state, the outputs of the first triggers 12 are set to O, and the outputs of the second triggers 13 are set to 1 (the circuit for the initial installation of the triggers 12 and 13 are not shown)

The pulse generator 1 continuously generates pulses that arrive at the first input of the splitter 2 frequency. With each arrival at the second input of the divider 2 of the frequency of the triggering pulse from the second generator 5 of pulses, it passes to the input of the first counter 3 a number of pulses equal to the division factor set on the first block of 6 switches.

In this connection, at the output of the first counter 3, the frequency of the signals arriving at the switch 4 exactly corresponds to the reciprocal of the planned target.

With the arrival of the next trigger pulse at the input of the frequency divider 2, the operation is repeated on

313

the input of the first counter 3 receives the next batch of pulses.

The division ratio of the first counter 3 is constant and is equal to the number of pulses emitted by the second generator 5 pulses for the planned worker within a day of time (shift, day, etc.). For example, in the proposed device, the division ratio of the first counter 3 is equal to the number of seconds in the work shift. Therefore, the pulse period from the second pulse generator 5 is 1 s.

At the same time, the pulses from the second generator 5 of the pulses arrive at the counting input of the second counter 7, consisting of n serially connected decimal places. The total number of decimal places is determined by the time it takes to make one unit of production.

P ,

where T is the time of production of one unit of production, min;

60 - conversion factor

T per second;

n - total number of decimal bits of the second counter 7

When calculating, the whole portion is rounded off to the large value.

The binary-decimal code from the second counter 7 is fed simultaneously to the first inputs of the comparison unit 8, the second inputs of which are supplied with the binary-decimal code previously dialed at the second block 9 of the switches.

If the scheduled time has expired and the current operation is not completed, then at the inputs of one of the blocks of the EXCLUSIVE OR 22 elements of one of the comparison blocks 8 the code is the same and a signal appears at its corresponding output. The signal from the output of this bit of code comparison block 8 is fed through the inputs of the AND 10 and OR 11 elements to the inputs of the flip-flops 12 and 13.

At the same time, the second trigger 13 remains in the initial state, and the first trigger 12 switches at its output and, respectively, at the inputs of the OR element 11 and the second element AND 14 signals appear. In this connection, the pulses from the generator 5 pulses through the input of the second element

6254

And 14 is fed to the input of the third counter 15, controlling with the help of the decoder 16, the indicators of the board 17, as well as to the corresponding input of the signaling unit 18. The signaling unit 18 is turned on and informs in the form of light and sound signals about the lag of the actual time of the current operation from the base or the simple equipment, and the board 17 records this time.

After actually performing the current operation, the sensor 19 terminates the operation and sends a signal to the input of the second trigger 13, which is switched, and at its output and at the corresponding inputs of the first element 10, the first trigger

0 12 and the second element And 14 signals disappear.

In this case, the first trigger 12 is set to its initial state and its output pulse, coming through the element OR 11, returns the second trigger 13 to the initial state, and due to the cessation of the supply of pulses through the second element 14 And the alarm unit 18 turns off and

Q time tracking is terminated.

In the event that the current operation is performed before the scheduled time, then from the output of the corresponding sensor 19 of the operation completion, a signal is received at the input of the second trigger 13.

In this case, the corresponding second trigger 13 switches both at its output and at the corresponding inputs

0 elements And 10 and 14 and the first trigger 12 signals disappear. The first trigger 12 remains in the initial state, and the second element And 14 does not transmit pulses to the inputs of the block 18

5 and the third counter 15. Therefore, the time counting is not performed and the signaling unit 18 is not activated.

After filling the first counter 3, which corresponds to the expiration

0 of the planned production time of a unit of production, the signal from its output goes simultaneously to the switch 4 and to the installation input of the second counter 7, which sets it to

5 original (zero) state.

Switch 4 after the arrival of the next signal switches on the display unit 20 (the planned part) the next combination of numbers, corresponding to 5

5P

at the given time, and from the sensor 21 of production, informing about the manufacture of the next unit of production (its actual part) - to the position corresponding to the next combination of its significant figures.

Comparing the smooth and actual production output, fixing the lag of the actual time of operations from the planned, identifying the cause and taking into account the operational downtime of the equipment, you can quickly monitor and regulate the production process.

Thus, the use of the proposed device in comparison with the known one allows to increase the information content and expand the area of its application due to the operative control of defending the actual time of each operation from planned, urgent detection of cases of lagging and operationally recording the time of lagging and equipment downtime. lag and downtime to take appropriate measures to fulfill the production plan of production for the planned slave Ochi period of time.
