Description

The invention relates to the field of automation and computing.

According to the main author. St. No. 229069, a device for monitoring the operation of production equipment is known. It contains workplace consoles, sensors, interrogator, linear unit, registration control unit, data processing unit, alarm control unit, synchronizer, dispatcher console, random access memory (RAM), print control unit, print device and tape punch.

Work station consoles and quantity sensors are polled sequentially through a polling unit with a central device with a polling pulse arrival rate. Information about simple equipment and quantity of output, accumulated in RAM for individual workplaces, can be printed out only in manual mode at the request of the dispatcher.

However, the known device cannot be used to retrieve additional information.

The aim of the invention is to expand the functionality of the device, i.e., provide for the retrieval of additional information from a number of jobs and the printing of this information in an automatic mode.

This goal is achieved by introducing process sensors, individual and general signal conditioners into the proposed device. The inputs of the individual signal conditioners are connected to the output of the polling unit and to the corresponding technological sensors, and the outputs are connected to the line unit and through a common signal conditioner to the input of the registration control unit.

The block diagram of the device is given in the drawing, where the signal sensors 1, work station consoles 2, polling unit 3, line 4, central device 5, communications 6, calling boards 7, synchronizer 8, registration control unit 9, processing unit are marked 10, RAM 11, printing control unit 12, alarm control unit 13, dispatcher console 14, board 15, tabletop light 16, dial pad 17, printing machine 18, belt perforator 19 process sensors 20 and individual 21 and total 22 signal conditioners .

The device works as follows.

Information about simple equipment is collected by sequential cyclic polling of consoles 2 by block 3. The polling frequency is synchronized through block 4 by synchronizer 8. Signals from sensors 1 are sent to cells of block 3, which are polled by the same signals as consoles 2, and further

B block 4 of the device 5. Block 4 receives information on common communication buses 6 for all workplaces.

Each board 7 is connected in parallel to its bus and indicates the numbers of those workplaces that cause or idle for any reason. From block 4, the call signals and simply arrive at block 13, which, by comparing the number of incoming signals for each service in two adjacent polling cycles, with a positive balance, generates a warning signal that includes a bell and a traffic light 16 on the remote control 14 in the corresponding service. In addition The numbers of jobs that are idle or call are displayed on the board 15 of the console 14.

Synchronously with the polling of the consoles 2 from the device I, information on the workplace is sequentially selected and fed to block 10, which from block 4 receives signals about the manufacture of parts, and from block 9 — signals about just x and a series of minute pulses. When a signal about manufacturing a part arrives, block 10 adds one to the selected number, and the result returns to RAM 11 to the same place.

In a certain cell of the work area, the time elapsed since the part was manufactured is accumulated. If this value exceeds the setpoint, the accumulation stops and the signal is generated simply. If the cause is named from the console of workplace 2, then the time accumulates in the device AND in the space provided for this reason. When the cause is not named, time accumulates in the space reserved solely for the fault of the worker.

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. The block forms the corresponding codograms and displays them through the perforator 19.

To correct the punched tape and display additional data on it, a typed field 17 was applied.

Additional information on the duration of the individual phases of the process is as follows.

When signals from the p-1 sensor 20 about the execution of controlled technological process operations (loading time, melting process) and polling signals from block 3 to the input of the former 21 are received, the corresponding signals are generated at the p-outputs unit 4 of the device 5 for recording in the cells of the device 11 reserved for this purpose. Upon receipt from the p-th sensor 20 of the signal about the implementation of the final operation of the process (unloading the furnace) and the polling signal from block 3, the driver 21 generates at the output a signal arriving at the input of the driver 22.

The output signal shaper 22, formed when a signal arrives at its input from any of the shapers 21, is fed to the input of the registration unit 9, allows the output information to print in automatic mode, blocking the manual print mode. Upon completion of printing information from one workplace from data processing unit 10 to the imaging unit 22, the signal “end of printing” is received. After that, block 22 generates a “blanking” signal, which, with a shutter speed delay, releases the manual print mode lock, and the device is ready to receive information on the new workplace.
