Description

The invention relates to devices for monitoring and recording the operation of machines and apparatus and is intended for comparing the planned and actual production of products.

A device is known for comparing the planned and actual production of products, comprising an actual output sensor, a pulse generator, a switch block, a time marker generator, a display, a frequency divider and a switch.

However, the presence of a time stamp generator does not ensure high accuracy of the device, since the accuracy of the device depends not only on the pulse generator, but also on the stability of the frequency of the time stamp generator, that is, the accuracy of the device is determined by the total error of the two generators.

According to the main author. St. 723631, a device for recording equipment production is known, comprising a display, the inputs of which are connected to the MMI outputs of the switch, one input of which is connected to the actual output sensor, and the other to the output of the counter, a frequency healer whose input is connected to the output of the pulse generator, and one of outputs - with the input of the switch unit, the prohibition unit, the inputs of which are connected to the pulse generator, to the other output of the frequency divider and to the output of the switch unit, and the output of the prohibition unit is connected to the input of the counter 2.

The disadvantage of the device is its low accuracy.

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

The goal is achieved by introducing a second counter into the device, a coincidence unit and a pulse shaper, whose input is connected to the second output of the inhibiting unit, the pulse driver outputs are connected to one of the second counter inputs and directly and through the matching unit to the commutator 382 inputs, the first output the prohibition unit is connected to another input of the second counter, the output of which is connected to the second input of the coincidence unit. The drawing shows a diagram of the device. The device circuit contains a display 1 controlled by the switch 2, the first one, whose input is connected to the sensor 3 of the actual output, and the second to the output of the counter 4, the input of which is connected to the prohibition unit 5. The inputs of block 5 prohibition are connected to a generator of 6 pulses, a frequency divider 7 and a block of 8 switches, the input of which is connected to a frequency healer 7. The input of the divider frequency 7 is connected to the output of the generator 6 frequency. The second output of the inhibit unit is connected to the pulse former 9, the outputs of which are connected to the second counter 10, the coincidence unit 11 and the switch 2, the output of the second counter 1O connected to the coincidence unit 11, the output of which is connected to the switch 2. The first output of the unit 5. the ban is connected to the second counter 10. The device works as follows. In block 8 of the switches set the planned target of manufactured products for the planned period of time. When the device is turned on, the generator 6 continuously produces pulses of the stable frequency, which are fed to the counting input of the frequency divider 7 and the first input of the prohibition unit 5. Block 5 prohibition transmits pulses to the input of the counter 4 and to the input of the counter 1O. In the frequency divider 7, the incoming pulses are counted. When the number of pulses in the divider 7 equal to the scheduled task installed in the switch block 8, the output of the switch block 8 removes the signal arriving at the second input of the prohibition block 5. The flow of pulses to the input of the counter 4 and the input of the counter 1O stops and the impulse taken from the second output of the prohibition block 5 starts the shaper 9 named after it. - pulses, which forms with a delay three successive pulses. The first impulse arrives at switch 2 and resets the planned task memory to the zero state during the planned time interval. The second impulse enters the coincidence block 11 and transfers the content information of the counter 1O to the switch 2, and at the same time, the planned task is displayed on the board 1 for the planned period of time. The third pulse resets the counter 1O to the zero state. The frequency divider 7 continues to count the pulses arriving at it and, when filled from its output, a signal is taken, which arrives at the third input of the prohibition unit 5 and returns it to its original state. The operation of the circuit is repeated, and the next batch of pulses arrives at the input of the counter 4 and the input of the counter 10, the number of which in the pack exactly corresponds to the scheduled task. , Koe4k {) the division result of the counter 4 is constant and equal to the time interval for which the production task is planned, multiplied by the ratio of the frequency of the Q generator of pulses to the total divider ratio of the splitter 7. At the output of the counter 4, the pulses are removed exactly after the time interval set to produce one units of production, i.e., the scheme implements a mathematical operation. g T t - the time required for the manufacture of a single product; - frequency of pulse generator b; total division factor of divider 7; the time interval for which the production task is planned (shift, decade, month); the planned task established in the block of 8 switches. After the arrival of the next impulse from the output of counter 4, switch 2 switches on board 1 (the current planning part) the next combination of digits corresponding to the scheduled task at the given time. From the actual production sensor 3 after the next part (assembly) has been manufactured, a pulse arrives at the second input of switch 2, which translates the display (its actual part) to the position corresponding to the next regular combination of its significant digits. By comparing the planned and actual output values, it is possible to control the rhythm of the production process at any time. Thus, in the proposed device, the accuracy is improved by elucidating the planned task aa on the scoreboard for a planned period of time while at the same time continuously monitoring the right level. vilnosgi work scheme current routine task.
