Description

. The invention relates to devices for the automatic control and accounting of equipment operation and can be applied to the systems of supervisory and automatic production control.

The aim of the invention is to improve the accuracy and information content of the device.

Figure 1 shows the functional diagram of the device; figure 2 - shaper technological pause; on fig.Z - temporary chart of his work.

The device contains a sensor 1 of the equipment condition, a generator of 2 pulses, a setpoint generator 3, a converter of 4 pulses, a working pause forming unit 5, the first counter 6, the first and second elements 7 and 8, the second counter 9, the third and fourth counters 10 and 11, the unit 12 causes a simple display unit 13 and the comparator 14.

Shaper 5 working pause (figure 2) contains the shaper 15 pulses, the first and second counters

16 and 17, register 18, comparator 19 and element 20.

The working pause forming unit 5 operates as follows (FIG. 3).

On the counting inputs of counters 16 and

17 pulses of time intervals from the generator 2 arrive. To the input of the pulse generator 15 and the recording input of the register 18 information, the output pulses arrive, on the leading edge of which the recording of the time information of the current working pause from the counting 17 to the register 18, and on the falling front - reset the counter 17 to the initial state. Information about the time of the current working pause from the bit outputs of the register 18 goes to the second inputs of the comparator 18, the first inputs of which receive information from the counter 16 about the time from the moment the equipment status sensor 1 triggers. If the time in the counter 16 exceeds the time of the current working pause (recorded in register 18), then at the output of the comparator 18 a signal is generated that the equipment’s rhythm disturbance (prohibiting the further arrival of time pulses to the counter 16) is generated,

The device works as follows.

Information about the plan for the reporting period (hour, shift, day) from the output of block 3 of the task of planned output at the beginning of the reporting period is recorded in the converter of 4 pulses.

The pulses from the second output of the generator 2 are converted in the converter 4 into a sequence of planned output pulses, which are fed to the input of the second counter 9 and the first input of the work 5 generator, the second input of which receives signals from the sensor 1 of the equipment condition. If the time before the arrival of the roundabout signal from the sensor 1 of the equipment state exceeds the time of the current working pause, then at the output of the generator 5 of the working pause, a signal is generated about the violation of the equipment’s rhythm, which arrives at the output of the device and at the second input of element 7 I, thereby allowing The pulse propagation from the generator 2 output to the second input of the third counter 11. When the third counter 11 reaches the technological pause setpoint, a comparative pulse inhibiting signal is generated at the output of the comparator s from generator 2 through element 7 AND and permitting through element 8 AND to the input of the fourth counter 10 is simply equipment. During the time given, the operator simply removes his cause and enters the cause with the help of the setting device 12 into the block 13. When the equipment condition sensor 1 triggers, the pulse from its output goes to the input of the finished product counter 6, and also sets the third counter 11 (technological pause) and shaper 5 working pause to its original position. In this case, in the display unit 13, the duration and cause are recorded simply, and on its indicator displays information about the work (plan, fact) and just the equipment is displayed.

When changing the plan (using the setpoint 3) for the next reporting period, the shaper 5 of the working pause automatically generates a pause corresponding to the changed technological conditions of the equipment operation.

Thus, the noBbmia device takes into account the accuracy of the equipment operation due to the introduction of an automatically controlled working unit.

pauses, expands the information content by taking into account the planned production, determining the moment of the equipment rhythm disturbance, the possibility of classifying downtime for reasons with indication and registration — all information.
