Description

one

The device is designed to coetrol and register the work of production equipment.

A device is known for monitoring the operation of production equipment, protected by the main bus. St. 229069, in which workstations consoles and signal sensors are connected via a polling unit to a line unit, which is connected to a registration control unit, a data processing unit, an alarm control unit on the synchronizer, an alarm control unit is connected to the dispatcher's control unit, - a data processing unit connected to a random access memory, a printing control unit and a registration control unit connected to a tape punch and a dispatcher console. On the basis of this invention, the ARP-1M installation (an automated recorder of manufacture), designed for the centralized collection, transmission and recording of primary information in the shops and enterprises of serial and mass production, has been serialized by domestic industry. It provides accounting for equipment downtime, accounting for the production of piece products, caused by an alarm, the formation of an intermediate information carrier with the results of equipment operation per shift for subsequent processing it to

COMPUTER. The main disadvantage of this device is the inability to directly use the information stored in the random access memory by different users of information. This is due to the rigid connection between the electric controlled printing machine used in the device as an element of the system that reproduces on paper

a form stored in the RAM information, and an unbalance control device connected to the controller console. According to this scheme, access to information on the operation of equipment stored in a random access memory is possible only from the dispatcher's zero, i.e. its direct user is one person's lens.

The purpose of the invention (i) is to spread the field of use. In the described device,

Which is improved, and compared to the well-known, mainstream auth. St. 229069, this is achieved by the fact that a switch, a descrambler, call blocks, indication blocks and a scoreboard are entered into it, with the switch

connected to the printing control unit, to the printing machine, to the input of the de-digitizer and to one of the outputs of the call unit, the other outputs of which are connected to the input of the output control unit and

one of the inputs of the corresponding blocks

indications, the other inputs of which are connected to the output of the decoder, and the outputs to the board. The drawing shows a block diagram of the device.

0.0 consists of signal sensors 1, zero stations 2, polling unit 3, line unit 4, central device 5, communication buses 6 caused by board 7, synchronizer 8, registration control unit 9, data processing unit 10, Operative storage device II, alarm control unit 12, dispatcher's control panel 13, board 14, traffic light board 15, dial floor 16, without machine, machine 17, belt punch 18, switch 19, decoder .20, local consoles 21, call blocks 22, blocks indications 23, board 24, which are interconnected, as per shown in the block diagram, and the printing control unit 25.

Information about equipment operation is collected by sequential cyclic polling by a block of 3 consoles and workplaces 2. The polling frequency is synchronized via a linear block to 4 by a synchronizer 8. Sipnals from sensors 1 for the manufacture of parts enter the cells of block 3 polled by the same signals as the consoles 2, and then to the linear unit 4 of the central device 5. Information to the linear unit 4 comes from all workplaces via common communication buses 6. Information is separated (tied to each workplace) in a temporary position NIJ arrival of incoming signals.

Scoreboard - 7 are connected in parallel, each with its own bus; For them, for one of the specific reasons, the numbers of the idle units of the equipment are displayed, which correspond to this board 7. Board 7 is installed in the corresponding service of the workshop and operates in the call or serviced modes.

From the block, there are 4 call signals and they simply enter the alarm control unit 12, which compares the number of incoming signals to each service (the reason is simple) S of two adjacent tread cycles. In case of a positive balance (the amount of sigals in the subsequent cycle is greater than in the previous one), block 12 includes in the corresponding service (board 7) a call and a traffic light 15 on the console 13. In addition, the numbers of workplaces that are idle or make a call The maintenance (repair) personnel are displayed on board 14 of the console 13.

. In the operational storage device 11, for each workplace, an area consisting of groups of cells is assigned. Each group is assigned to a given workbench for a specific reason simply or to account for the output from its piece products.

Siihroi with polling the remote controls 2 from the device 11 is selected sequentially, the information is sent to the workplace and enters unit 10, which receives from unit 4

signals about the manufacture of parts, and from block 9 - signals about simple equipment and a series of minute pulses. When a manufacturing signal is received on a given piece of equipment, block 10 adds one to the selected number and returns the result to device 1I to the same place. If this signal is not present, the selected number is returned to the device 11 without changing to the same place. The same operation is carried out but for each workplace with the accumulation of time just a piece of equipment for a specific reason. In the definition of the cell area of the worker. accumulates time

expired since the last part was manufactured. If this value exceeds the setpoint, its accumulation stops and the start signal is generated simply. If from the console of workplace 2 is named specific

the cause (a corresponding message is typed), the time is simply accumulated in the device 11 at the place reserved for this reason. When the cause is not named, time simply accumulates in the space provided for

simply through the fault of the worker serving this piece of equipment. Signals about simply x from block 4 also arrive at block 9, in which from block 10 the signals about the beginning or the end come simply. Block 9 forms

corresponding codograms and displays them through a tape punch 18.

To correct the tape and output to it positive data in the device is a dial pad 16, which is located on the remote control 13.

If necessary, the indication (registration) accumulated in the information device; and, it is displayed on a paper form using the printing machine 17, through the block

print management 25.

In addition, the device includes a switch 19 and a decoder 20 connected to local consoles 21.

If it is necessary to obtain information on the state of the equipment and data on its operation (downtime for reasons, number of parts manufactured from the beginning of the shift) on the appropriate local console

21, a signal is input from the output of call block 22 to a print control block 25. At the same time, the signal enters switch 19, setting it in a position where its output is connected via decoder 20 to the input of corresponding display block 23 prepared for receiving information signal from the output of the call block 22. At the time of sampling the relevant information from the operational

the storage device 11 it-from its output through the data processing unit 10 and the control unit for printing 25 is fed to the switch 19, and from it through the decoder 20 to the input of the corresponding indication unit 23.
