Description

one

The proposed device relates to the field of telemechanics and is designed to control objects in the presence of several sources of command signals.

Devices for remote control of objects are known, comprising command blocks with closing and switching contacts, a relay matrix in which the closing contacts of the respective relays are connected in pairs in parallel and included in the control circuits of the objects, and a power supply unit.

However, in known devices for transmitting information with a two-position code from several command blocks, at a suitable point, it is necessary to have an appropriate number of relay matrices and to increase the number of communication channels.

The proposed device is characterized in that in it relays located at the intersection of even rows and columns of the matrix are connected to each power supply bus through individual closure contacts of command blocks connected to the switching contact of the first command block for even rows and columns. The relays located at the intersection of the odd rows and columns of the matrix are via the closing contacts of the command blocks for the odd rows and columns connected to the switching contact of the second command block.

This makes it possible to significantly simplify the device, i.e., if necessary, the simultaneous receipt of commands from two command blocks is limited at the receiving point to one unified relay matrix.

The drawing presents the principal electrical circuit of the proposed device.

It contains a matrix assembled on the relay 1-8, grouped in columns 9-12, lines 13-16 and having respectively closing contacts 17-24 in the object control circuits, command blocks, respectively, with closing contacts 25-32 and 33-40 and the switching contacts 41-44 and the power supply unit with 45, 46 women. The device operates as follows.

When commands are received from the first command unit, its closing contacts are closed in one of the combinations: 25, 26, 29, 30 or 25, 26, 31, 32, or 27, 28, 29, 30, or 27, 28, 31, 32. Simultaneously change their position

switching contacts 41, 42, which characterize the operation of the first command block.

When commands are received from the second command block, its closures are closed.

contacts in one of the combinations: 33, 34, 37, 38 or 33, 34, 39, 40 or 35, 36, 37, 38 or 35, 36, 39, 40. The position of the switching contacts 43, 44 characterizing the Prizpak work of the second command unit. Let the device be given a command from the first command unit by closing its closing contacts 25, 26, 29 and 30. At the same time, columns 9, 10 and lines 13, 14 are connected to the power supply buses 45, 46 through the closing contacts 25, 26, 29 and 30, closed opening pairs of switching contacts 43, 44 and short circuiting closing pairs of switching contacts 41, 42. Relays i and 2 are energized, triggered by their closing contacts G / 8, and an executive signal is output to the control value of the corresponding object. If, during the passage of this command, a command is received from the second command block, for example, by closing its closure contacts 35, 36, 39 and 40, then column 11 is connected to power supply spikes 45, 46 via short-circuiting contact 35 and locking A pair of non-switching contact 43 and line 15 through a short-circuiting:, contact 39 and a closing pair of switching contact 44, which causes the relay 7 to trip. The switching contact is 43, and the connection is 0; lines 13 through closed closing contacts 29 are broken by an open disconnect; by switching the pair with contact 44. The connection circuit of column 12 through the closing closing contact 36 is broken by the opening contact of disconnecting contact 41, and the connection of connection 16 through disconnecting contact 40 is open. an open breaker with a pair of a switching contact 42. Thus, on command from the first com- mand block, wines 45, 46 are connected to column 10 and line 14, and according to the command from the second command Nogo unit - for column II and the line 15. The other columns and rows are disconnected from the power unit. Relay 1 releases, its normally open contact 17 opens. The command from the first command block is issued only by the closed closing contact 18, and the command from the second command block is issued only by the closing closing contact 23 of relay 7. When the command from the first command block is removed, its closing contacts 29, 30, 25, 26 open and relieve the voltage from row 14 and column 10. Relay 2 releases and opens the closing contact 18. At the same time, the switching contacts 41, 42 return to their original position. Thus, through the closed closing contacts 36, 40, the voltage is connected to column 12 and line 16. Relay 8 is activated and closes the closing contact 24. Object of the Invention A device for remote control of objects, containing command blocks with closing and switching contacts, a relay matrix in which Coptic closing act. The corresponding relays are connected in parallel and connected to the control circuit of the control circuit, ect, power supply unit, which, in order to simplify the device, in the psm relay, located at the intersections The even rows and columns of the matrix are connected to each power supply bus through the individual contacts for even rows and columns of the closure contacts of the commanding units connected to the switching contact of the first command block, and the relays located at the intersection of the honorary rows and columns of the matrix are connected to each bus power supply through individual for odd rows and columns closing contacts of command blocks connected to the switching contact of the second command block.
