Abstract

The invention relates to electric automatics devices and can be used in automatic line control systems. The purpose of the invention is the expansion of technological capabilities by ensuring the independent operation of each mechanism during its autonomous control mode. For this purpose, four control mode buttons, four additional warning lamps and a control mode relay, corresponding to their own, are interconnected with each other and with 1 spin of the control unit, which contain control panels with alarms, operating mode selectors and operating mode relays. Thus, both mechanisms, functionally interconnected by the organization of control, can, for example, operate in different modes, which can be switched on from one of the control panels. In this case, from another control panel, it is possible to make similar switchings, I hp. f-ly, 3 ill.

The invention relates to electric automation devices used in production process control systems of various industries, which include functionally related control organization mechanisms, in particular, automatic line control systems.

The aim of the invention is to expand the technological capabilities and improve the quality of the information content of the decentralized device, control the mechanisms of the automatic line by ensuring the independent operation of each mechanism of the first regime when the autonomous control mode is on.

I FIG. 1 shows a schematic diagram of the device; in fig. 2 - a fragment of an on-board control panel of one functionally connected — I control organization organization of the mechanism; in fig. 3 - the same, another functionally i connected by the organization of control of the I mechanism.

; The device contains four buttons of the following: control presses: “Open mode, 1.2 mode; “Offline mode - 3, 4, six buttons. the main mode of operation: “Automatic - 5, 6; : “Semiautomatic - 7, 8; "Adjustment - 9, 10, relay 11 control modes, six relays of basic operating modes:" Automatic - 12, 13; “Semiautomatic - 14, 15; "Adjustment - 16, 17, four additional warning lights of control modes:" Common mode - 18, 19; “Offline mode 20, 21; six warning lights of the main modes of operation: “Avtomat - 22, 23; “Semiautomatic - 24, 25; "Adjustment - 26, 27. A group of buttons 1, 3, 5, 7, 9 and signal lamps 18, 20, 22, 24, 26 are placed on the remote control 28 of the same mechanism, and a group of buttons 2, 4, 6, 8, 10 and signal lamps 19, 21, 23, 25, 27 - on the remote control 29 of another mechanism.

The device works as follows.

The control in general mode is performed from any console of two functionally connected control mechanisms, for which button 1 or 2 is pressed, the relay of 11 modes and signal lamps 18, 19 of the general control mode are turned on. Contacts 11.1, 11.3, 11.4, 11.5 are closed, and contact 11.2 is opened. The desired mode of operation is selected, for which one of the buttons is pressed: for the mode “Automatic - 5 or 6; for the “Semiautomatic mode - 7 or 8; for the mode “Setup - 9 or 10, while in parallel the relays of operation modes of both mechanisms are turned on:“ Automatic - 12, 13, “Semiautomatic - 14, 15,“ Adjustment - 16, 17, and alarm l.mpy “Automatic - 22, 23; "Luavtomat - 24,

0

25; “Adjustment - 26, 27 respectively. The closing contacts 12.1, 13.1, 14.2, 15.2, 16.3, 17.3 are used as contacts of the mode relays 12, 13, 14, 15.1, 17, and the opening contacts 12.2, 12.3. 13.2. 13.3, 14.1, 14.3. 15.1, 15.3, 16.1, 16.2, 17.1, 17.2 are necessary to exclude the possibility of switching on two modes of operation simultaneously. In the offline control mode, the switching of the operating modes of the mechanisms is carried out separately for each mechanism. To switch on the autonomous mode, one of the buttons 3 or 4 is pressed, the relay 11 of the control modes is turned off, the contacts 11.1, 11.3, 11.4, 11.5 open, and therefore also the electrical connections between the mode relays 12-13, 14-15, 16-17 stops, contact 11.2 closes, the common mode warning lights 18, 19 are turned off, and the self-contained control lights turn on the warning lights 20, 21.

To activate one of the modes of operation in the autonomous control mode, you must press the button of the corresponding mode on one of the consoles 5 or 7, or 9, and on the other: 6 or 8, or 10, and the corresponding “Auto, “Semiautomatic or“ Setup, i.e. for one mechanism, relays 12. 14, 16, and for the other, relays 13, 15, 17, respectively, of pressed buttons. In addition, the on mode is monitored for one mechanism with signal lamps 22, 24, 26, and for the other 23, 25, 27.
