(54) DEVICE FOR CONTROL AND ACCOUNTING OF EQUIPMENT WORK

I

The invention relates to devices for the automated control of equipment operation and can be applied to dispatching and automated production control systems in all sectors of the industry.

A device for monitoring equipment operation is known, comprising signal sensors, work station consoles, communication lines, a central device, matching units, memory blocks, registration units, switches, and a display board 1.

This device uses a complex system of cyclic polling and synchronous processing of information, which requires a large number of connecting lines, since polling and information about the causes simply come through individual connecting lines, which significantly increases the cost of equipment, its installation and maintenance .

The closest in technical essence to the present invention is a device for monitoring and recording equipment operation, comprising workplace consoles with switches, a pulse generator, a decoder a block of pulse counters, and a display unit.

the output of which is connected to the input of the equipment display, as well as containing control panels, an output unit, an OR element, a code generator, a control unit, switches, a general equipment condition analysis unit and a polling board 2.

The disadvantage of this device is its high complexity.

The purpose of the invention is to simplify the device.

The goal is achieved by the fact that in the device for monitoring and recording the operation of production equipment, containing workplace consoles with switches, a pulse generator, a decoder, a block of pulse counters and a display unit, the output of which is connected to the display input

5 of the equipment, the input of the first workstations console is connected to the output of the pulse generator, the first output of each workstations console is connected to the input of the next workstations console, the second outputs of which are connected to the input of the decoder, the output of which is connected to the inputs of the display unit and pulse counters unit, each console The workplace is made of an encoder and pulse former, the first output

which directly and through the switch is connected to the inputs of the encoder, the output of which is connected to the second output of the desk, which input is connected to the input of the pulse former, the second output of which is connected to the first exit of the desk.

The drawing is a block diagram of the proposed device.

The device contains 1 workstations connected in series. Each work station console 1 contains a shaper of 2 pulses connected directly and via switch 3 to the encoder 4. The encoder outputs 4 of all of the console 1 work stations are connected to each other and to the input of the decoder 5, the output of which is connected to the input of the pulse counters block 6 and to the input display unit 7, the output of which is connected to the input of the equipment display 8. Output gbneratora 9 pulses connected to the input of the imaging unit 2 pulses of the first console of the workplace.

The device works as follows.

The pulse generator 9 generates pulses at certain time intervals (for example, after 1 minute). The frequency of the generator 9 is set depending on the required accuracy of the device. When the first pulse arrives from the generator 9 pulses at the input of the imager, 2 pulses of the first console 1 of the workplace, the imager 2 pulses outputs two pulses to the outputs. The first pulse arrives at the input of the encoder 4 directly and when the switch is closed (for example, for the first reason just equipment) through the closed contacts of switch 3. The second pulse with a time delay relative to the first arrives at the driver 2 pulses of the second console 1 of the workplace, where its processing is similar .

From the output of the encoder 4, a parallel run is taken, including the data on the equipment number (of the work station console); The number of reasons is just equipment.

The equipment number is encoded by the encoder and has a constant value, and the reason number is simply that the equipment has a different value depending on the position of the switch.

The parallel code along the connecting lines (their number is determined by the digit of the codes for the numbering of the workstations and the reasons is simple) goes to the encoder 5, which sends an impulse to the output bus corresponding to the number of the workplace and the reason established in it. The display unit 7 fixes simply in the corresponding memory cells. On the table 8 of the equipment, the idle equipment number is displayed and the reason is simple. In addition, at 8 of the equipment, a visual monitoring of the polling of the workstations' 1 workplaces is carried out.

If any of the console workstations are damaged, the equipment display board 8 will record a shortened demand cycle. Block 6 of pulse counters maintains a total account of equipment downtime for each of its causes.

Thus, when the next pulse arrives from the generator 9 pulses, all the consoles of 1 workstations are polled.

The proposed device is much easier known.
