Description

This invention relates to electric automation devices.

The purpose of the invention is to increase the safety of work.

The essence of the invention is that in order to increase security when transferring the circuit to another mode of operation, characterized by a higher degree of automation, it is necessary to receive confirmation from each console about the change in mode.

Fig. 1 is a schematic diagram of the device; Fig. 2 is a continuation of the diagram.

The device contains a relay 1 control mode with a winding and working contacts 1.1-1.11, a relay 2 times with a winding and contact 2.1, eight relays of the main operating modes: Automatic-3, 4, respectively, with contacts 3.1-3.3 and 4.1-4.3, Semiautomatic - 5, 6 respectively with contacts 5.15 .6 and 6.1-6.7, Setup - 7, 8 respectively with contacts 7.1-7.8 and 8.1-8 8, Change of mode -9, 10 respectively 9.19 .7 and 10.1-10.7. six mode buttons

Controls: General mode 11 and 12, Automatic mode 13 and 14, Change mode 15 and 16, six buttons of the main mode of operation: Automatic 17 and. Semi-automatic 19 and 20, Setup 21 and 22, six warning lights of the main operating modes: Automatic 23 and 24, Semiautomatic 25 and 26, Setup 27 and 28, six warning lights of control modes: Common mode 29 and 30, Offline mode 31 and 32, Change of mode 33 and 34. Button group 11, 13, 15, 17, 19, 21 and signal lamps 23, 25. 27, 29, 31, 33 are placed on the remote control of one mechanism, and a group of buttons 12, 14, 16, 18, 20, 22 and signal lamps 24, 26, 28, 30, 32, 34 - on remote control ma.

The device works as follows.

Control in general and autonomous modes, respectively, is carried out from any console of two functionally connected control organization mechanisms or separately for each mechanism.

To switch from autonomous to general mode with a higher level of av.

themes need to press on each remote control buttons 15 and 16 Change mode, then press buttons 11 and 12 General mode. Signal lamps 33 and 34 and relays 9 and 10 change the mode, the closing contacts 9.1 and 10.1 of which form self-coupling circuits, and the closing contacts 9.3 and 10.3 connect the control mode relay 1 winding to the power supply terminals while the button 11 is pressed.

The closing contacts 9.2 and 10.2 of the mode change relay form the power supply circuit of the time 2 relay coil. After a time delay, a trip is made via contact 2.1 of the relay coil circuits.

9 and 10, time 2 relays and warning lights 33 and 34.

In this way, the circuit is switched from autonomous mode to generic mode.

To transfer the device during general control from the Setup or Semiautomatic mode to the Auto mode, on each remote control, the 15 and 16 button Change mode is pressed. This includes relays 9 and

10 Mode change, relay 2 times and signal lamps 33 and 34 as described.

When the relay 9 and 10 are activated, the contacts 9.4, 9.5 and 10.4, 10.5 are closed, thus preparing the switching circuits of the relay 3 and 4 Auto.

In order to transfer the device during general control from the Setup mode to the Semiautomatic mode, buttons 15 and 16 on each console are pressed. Mode change. This includes the change mode relay 9 and 10, the time relay 2 and the warning lamps 33 and 34 in the same way as described.

When the relay 9 and 10 are activated, the closing contacts 9.6, 9.7 and 10.6 and 10.7 prepare the switching circuits of the relay 5 and 6 Semiautomatic device.

Thus, due to the possibility of confirming the command. A change in the mode of the device makes it possible to increase the safety of the work of the service personnel.
