Description

The invention relates to automation and computing and can be used in production control systems to equip the dispatching services of industrial enterprises.

The aim of the invention is to improve the accuracy of the device.

The drawing shows the function: the device diagram.

The device contains the first counter 1, the key 2 reset, the generator 3 pulses, the first divider 4 frequencies, counters 5, switches 6, the third element is NOT 7, the first 8 and second 9 elements are AND, the fourth divider is 10 frequencies, the first element is NOT 11, fifth a frequency divider 12, a delay element 13, an OR element 14, the second 15 and sixth 16 frequency dividers, an AND-NE element 17, a trigger 18, an AND element 19, a third frequency divider 20, a link 21 and a second counter 22.

Elements 5, 6, 8, and 9 constitute the setting knobs of the 23 code by decade.

In addition, the device includes a second element NOT 24.

The device works as follows.

At the output of the OR 14 element, the number of pulses, given by the switches 6, is produced in a time equal to. For example, 1 s, this series of pulses is fed to the input of the element And 19, on the other input of which the high potential is preliminarily set from the output of the trigger 18. From the output of the element I, the 19th series of pulses passes to

the input of the divider 20 with a given coefficient of 40 pulses, which arrive at the divisor divider, for example, ep 28800, where the accumulation of the number of pulses occurs before the divider overflows 20. Since in each interval equal to 1 s, the specified number of pulses

4, with a predetermined ratio of detonations, for example, 10,000. At the output of the division of body 4, pulses of frequency 1 Hz appear, which arrive at the control inputs of counters 5. At the same time, the potentials from the switches 6 arrive at the installation input of each counter 5 with plan values set on them

with an interval proportional to the number of pulses in the interval. These pulses arrive at counter 1, where it occurs. their summation. Counter 1 provides - 0 indicators, for example, in digital

It also has a galvanic source to store information in the event of an unexpected power outage. From the output of the counter, information about the current value of the planned indicators is supplied in a potential code through a decoder to an indicator (not shown), where the current values of the planned values are displayed numerically.

indicators. From splitter 20, via communication line 21, the pulses arrive at the shop display unit, a similar dispatch unit on which the current values of the planned indicators are digitally displayed.

Reset, i.e. installation, device nodes, production 5

The pulse from the output of the element is NOT 7. From the third output of the divider 4 to the input of the divider 15 short pulses are received with an interval of, for example, 1 s. . At the output of the divider 15, pulses appear with an interval of, for example, 1800 Cf arriving at the second input of the AND-NE element 17 and to the input of the divider 16, at the output of which pulses appear at an interval of 14400 s, which set the trigger 19 along its first entering the state when a low potential appears at its output, which prevents further passage of pulses through AND 19 at its second input to divider 20 until an input from the output of the NAND element arrives at the input of the trigger 18 17, which is formed from entering the inputs of the elements and NAND 17 pulses dlitelnoe-,

ti proportional to the end-to-end division factor from the input of the divider 15 to their outputs. Thus, the generation of the planned 5 indicators from the output of the setter through 14400 s and the automatic resumption of generation after 1800 s occurs. The generator 3 generates at the resonant frequency of quartz, for example 10 kHz, im0

40 pulses that go to del-

4 with a predetermined division coefficient, for example 10,000. At the output of divider 4, pulses with a frequency of 1 Hz appear, which are sent to the control inputs of counters 5. At the same time, the installation input of each counter 5 receives the potentials from the switches 6 in accordance with the set on them the values of the planned

formo These potential values are pulse-written to the first inputs of the counters 5. From the output of the generator 3, the pulses go to element 55 And 8 of the first setter 23, to the input of the first divider 4, to element 13 of the delay, from the output of which the pulses are shifted by half the follow-up period, go to the inputs of the elements

And 9 of the first, second and third sensors 23 and pass through the element AND, 9 of the first setting device and the element OR 14 at the input of the element And 19, from the output of the element And 8 of the first setting device, go to the input of the counter 5 of the first setting device and read previously recorded with switches 6 values to the pool. Upon completion of the reading, the output of the counter 5 appears with a low potential, which prohibits further passage of the pulse through the AND 8 element and phase-shifted pulses through the AND 9 element of the first setter and is allowed to pass the pulses through the divider 10 pulses to the second the input of the first element And 8, as well as through the element NOT 11 of the first setter, permission is given to the third inputs of the second elements And 9 of the second and third setters and to the first element And 8 of the second setter. The pulses from the output of the divider 10 with a frequency of 1 kHz pass through the first element I 8 of the second setpoint device to counter 5, where the previously recorded values are read to zero, after which the output of the counter 5 of the second setter exhibits a low potential, which elements 8 and 9 of the second setter prohibits further passage through them of pulses from the output of the first divider 10 and delay element 13 and is allowed on the first input of the divider 12 passing of pulses through its second input and through the element 24 through the third input of the first el And 8 through its second input and through the fourth input of the second element I 9 through its first input of the third setter, and the passage through the first and second elements 8 and 9 is stopped at the end of reading the previously recorded planned value into the counter 5 third setter. A series of pulses from the outputs of the second elements And 9 of the first, second and third setters pass to the inputs of the element OR 14. At the last, a series of impulses from three decades is connected to its inputs. From the output of the OR 14 element, a series of impulses is transmitted to the second input of I1 9 and then to counters 1 and 2.

Before the operation of the device, switches 6 select the number of planned output per shift. The key 2 makes clearing the dividers, the binary-decimal counters of the set indicator setter decade, and also the dividers by their installation inputs set by the second input of the trigger 18 to the initial (enabling) position, clearing the divider 20.

A series of pulses from the outputs of the second And 9 elements of the first, second, third, and so on setters enters the OR 14 element, where it is converted into a continuous series of pulses that enters And 19 from divider 20 with a given division factor, for example, 28800. the output of the divider 20 single im-, pulses with an interval inversely proportional to the number of pulses in a series in 1 s, go to the count and indication where accumulation, decoding and highlighting of the planned number of products occurs on a cumulative basis.
