SU760141A1 - Device for monitoring and setting industrial rhythm - Google Patents

Description

The invention relates to devices for monitoring and recording equipment operation and can be applied primarily in operational control systems, including with automated production management, to control the production rhythm setting.

Known devices for monitoring the quality of work of machines and devices, 10 which contain counters of industrial products, equipment status sensors and a delay element, a pulse generator, an OR element, a counter and a unit timer of a 15 time period of O.

The disadvantage is its low accuracy.

The closest in technical essence to the Invention is a device for monitoring the operation of production equipment, which contains a control unit for the deviation of the actual output from the planned one, consisting of sensors of the controllers, workstations, a polling unit, a matching unit, a synchronization unit, a unit control, tracking unit, memory unit, program block nd comparator, and the registration unit, consisting of 30

from the digital display panel and the deviation alarm panel [2].

However, the use of this device does not automatically determine the required performance of the equipment, does not allow to determine the maximum allowable stopping time, for example, for preventive, repair work, does not allow to predict the implementation of the plan while continuing to work with the previous performance, which makes it difficult to develop objective operational management decisions especially when it is economically inexpedient to develop at the enterprise Noah management system (MIS) based on the mainframe.

The aim of the invention is to expand the functional capabilities of the device, providing increased * efficiency and quality of production management by creating automated control systems based on the device of the proposed type without large computers, the use of which in some cases may not be economically effective.

This goal is achieved by

FIG. 1 shows a block diagram of the device; in fig. 2 shows a graph of the dependence of the number of manufactured products on the time of work of the equipment “Zhiyak” "'’ "

The device contains a block 1 of controlling the deviation of the actual output from the planned one, block 2 of the registration, block 3 ’Performance determinations, block 4 of definitions for permissible 'idle time and block 5 for predicting the implementation of the plan.

The device works as follows.

Before starting work, in block 1 of the control of the deviation of the actual output from the planned, information on the specified planned output is entered, in block 3 of the Performance Definition - information on the specified planning time TF, in block 4, determining the allowable downtime - information on the specified planning time T _a and also about the maximum possible production of this section or obrudanyan P (* _IC , in block 5 of forecasting the fulfillment of the plan - information on a given planned product branch Ν _δ and about a given planned time for the execution of plan T _5. With the commencement of the work, the control unit for deviation of actual output from planned produces signals proportional to actual output, current time and negative actual output of production from planned, Signals proportional to the current time, deviation of actual output from the planned, arrive in block 3 performance definition unit 4 definition acceptable. idle time. In block 5, the prediction of execution / pLyo''n <yt'yuyy? T '''' yoRt n aly, is proportional to the allotment of the output of the product and the current time value. The input signals are converted in block 3 of the performance determination into a signal proportional to the magnitude of the required performance / which is 0xp <R $ Fill Plan, in block 4 of the definition I®

allowable idle time is in the signal proportional to the value of allowable idle time, i.e. the time after which the plan execution is still possible under the condition of working with the maximum performance, in the prediction block of the implementation, the plan - into a signal proportional to the magnitude of the possible deviation of the actual output from the planned by the end of the planned time interval, subject to working with the performance equal to performance to this point in time. These signals from the outputs of the listed blocks are transferred to the registration unit, where they are converted into a form that is easy to read.

The nature of the functioning of blocks 3, 4, 5 can be understood from the analysis of the graph shown in FIG. 2, and analytical expressions.

Since at each instant of time, block 1 controls the actual output of the playa n _t and its deviation from the planned one (Ν _β -η _τ ), then the required performance is _Pspreb . , ensuring the implementation of the plan for a given, planned time T _e , can be determined by the dependence

The proposed device can be used for control and operational management of production directly at the facility management (workplace). In this case, the output data from the registration unit goes directly to the operator who controls the process of functioning of the controlled object. It is also possible to use the proposed device in the operational control channel of the operational calendar scheduling and automated control system subsystem. In this case, the information from the output of the proposed device is transferred to the central automated control system post.

The proposed device makes it possible to significantly reduce the role of the subjective factor in determining the required performance and the allowable idle time. The device allows you to quickly and reasonably introduce adjustments to the production plan when there is a change in productivity, to assign the optimum modes of equipment operation.
