Description

one

The invention relates to devices for monitoring and recording key performance indicators; characterizing the planned production and actual production of cyclically boosted equipment, such as rolling mills.

A device for monitoring equipment performance is known; it contains a pulse generator with a fixed pulse frequency corresponding to the reporting period, a counter with a conversion factor corresponding to the reporting period, a switch block for setting a scheduled task, a frequency divider, an impaler, a counter, a switch, a switch with memory elements and counters ,, actual output sensor t I

However, this device can keep track of production on only one unit and does not allow monitoring the specified parameters simultaneously on several units, for example, in the pipe manufacturing line, the section of the plate-finishing workshop, where the number of control objects reaches several tens of units. only if the actual processing time of the product is equal to or greater than the planned. If the production of the controlled object is higher. planned, then the device gives a large error in the calculation and registration of the planned production, since the impulse to fix the planned task is removed from the coincident unit with equal actual and planned processing time of the product

The closest in technical terms to the offer is a device for monitoring and recording the planned and actual production of products, containing the sensor of the actual output of the product, the generator of the planned production, the unit of time of the reporting period, sumat1matfr and the G2P pulse generator.

In this device, the pulses of the current planned output are generated according to the N value of the planned output for the reporting T and with the frequency N.T served by the AI at the input of the counter. with; ni; vr-ii; i the input of which is received is k; ITM VI144, with 1 tachi facti; ih, gi

However, the use of this device is limited to using it to control the performance of only one unit. To account for the generation of a group of units in the production lines, several such devices are required, which increases both the equipment and significantly impairs the performance.

The purpose of the invention is to expand the field of application of the device for monitoring and recording equipment performance by providing control over production over several objects.

The goal is achieved by the fact that the device containing the actual sensor and the generator of the planned production, the controller of the reporting period, the adder and the pulse generator, additional sensors of the actual and controller of the planned development of products, the number of which is equal to the number of cores: objects, the pulse distributor , the block of memory elements, the blocks of the IPI and I elements, the controlled commutator and the counting block, the code of the pulse generator is connected to the input switch of the pulse distributor ,, zero you Which one is connected: to the installation input of the block of memory elements, and single to the input of the adder, the bit outputs of which are connected to the counting inputs of the block, memory elements whose outputs are connected to the inputs of the block of elements I connected to the first group, the output of which is connected to the input of the controlled switch, whose inputs are connected to the inputs of the counting unit combined into the first group, the second group of inputs of which is connected. To all sensors of actual production output, other outputs are distributed L11tal is grouped and connected to the control inputs of the controlled switch and scheduled output setting units, and its last output is connected to the time period setting unit, the output time and output time setting devices of the reporting period are connected to the INHIHM OR elements, the outputs of which are connected to the combined , wto; (euyu group of inputs of the block of elements And; the last switch is connected to the second one;

The drawing shows a block diagram of a device for monitoring and recording the performance of four objects.

The device contains a counting unit 1, consisting of two groups of meters connected to the inputs, respectively, with the outputs of sensors 2.1-2.4 of the actual output and a group of outputs of the switch 3, controlled by the OUTPUT 2-5 of the distributor 4. These outputs of the distributor are connected by control inputs 5.1-5.4 planned production. To the last, sixth, the output of the distributor connected setpoint 6 time of the reporting period. The information outputs of all the setpoints are combined bitwise using a block of 7 OR elements and connected to a group of signal inputs of a block of 8 I elements, a group of control inputs of which through a block of 9 memory elements are connected to the bit outputs of the adder 10, and the output is connected to a gate input switch 3. The installation inputs of block 9 are connected to the zero input of the distributor 4, and the counting input of the adder 10 with its first output. An impulse generator 11 is connected to one of the inputs of the distributor 4, the other input of the distributor is connected to the last output of the switch 3.

Distributor 4 for each signal from generator 11 (or from the last output of switch 3) generates on each of its codes the pulses separated in time.

The switch 3 on the control signals from the distributor 4 transmits a signal arriving at its clock input C from the block 8 of elements I, on one of the output channels to the counting unit 1.

The choice of the capacitor Esummator .10 and the frequency F of the generator 11 pulses is made on the basis of the maximum possible planned setting Ndl of controlled objects, while

,, with. F.-f,

where T is the time of the reporting period. The setpoint m of the setter 6 of the time code of the reporting period is determined (in the corresponding code of the adder 10) by the difference tnzE-PT.

This choice of the specified parameters provides a one-time adjustment of the device circuit for monitoring n objects over the entire range of specified plan targets at one time setpoint of the reporting period.

The memory elements block 9 is intended for fixing and storing for the whole operating cycle of the distributor 4 the fact of the transition of the corresponding binary bit of the adder 10 from O to 1.

The device works as follows.

At the beginning of the reporting period, the pulses from the generator 11 begin to arrive at the input of the distributor 4, which for each such signal processes a cycle, forming at its outputs distributed pulses in time. At the same time, the output pulse O sets the memory block 9 to the initial state, the output pulse 1 is written to the adder 10.

When the first pulse arrives at the adder 10, its first binary bit goes from state 0 to state 1, the signal of which indicates that the first memory element of block 9 is set to 1 and a signal appears at its output that prepares the first element of block 8 Next, the pulses from the outputs 2-6 of the distributor 4 are alternately connected through the corresponding element 7 OR to the signal inputs of block 8, the code of the corresponding setpoint generator and synchronously with it the corresponding channel of block 3. If in any settingter the value of the planned setpoint in the higher bit If it is equal to 1, then through this channel on the code of block 3 a pulse is generated, which is fed to counting block 1 to calculate the planned output.

With a value of 1 setpoint from the accounting period in this bit of setting device 6, the last output of switch 3 is sent to the second input of distributor 4, which allows working the second cycle of distributor 4 in the same way as the generator 11 impulse.

In the adder 10, 2 pulses are counted and its second bit goes from O to 1, etc.

At the end of the reporting period, T to the distributor 4 comes from the generator 11 at its first input
