Abstract

The invention relates to telecommunications and can be used in. automation devices and radio systems. The aim of the invention is to simplify the design. The switching nodes are double-wound polarization relays. The switch is controlled using key columns control and row control keys. The power to the winding of each relay is realized both vertically and horizontally. Therefore, if the relay 10 is located in the switching node on the column and the row, where one of the keys is turned on, the disconnecting winding of this relay will receive power. If the relay is located in the switching node where the key is switched on, then the switch on winding of this relay will be powered. 1 il.

The aim of the invention is to simplify the design of the switch.

The drawing shows a circuit diagram of the switch.

The matrix switch contains in the switching nodes 1-9 a polarized relay 10 and vertical control circuits (keys 11) and horizontals (keys 2: one terminals of the enable windings 13 and; the windings 14 disconnect all the 10 I relays of one column, respectively, through I first 15 and the second J6 groups of the spreading diodes are combined and connected to the closing contact J7 of the key I of the control circuit of the vertical I of their column, the other outputs of the retaining: current of 13 turning on all the relays J About one line are combined and connected to the closing parts of the switching contact 18 key 12 c control circuits horizontally on their own line, one pins; windings 14 disconnecting all relays jO i One line through the third group of 19 decoupling diodes are combined and connected to the closing contact 20 of the key 12 of the control circuit along its horizontal line; I WOTOK J4 disconnecting esekh 10 single column; through the fourth group of 2 connecting diodes combined and j connected to the break contact 22 I of the control circuit key 11 11 vertical column, and other winding pins 14 disconnecting all 10 relays one line through pt The first group 23 decoupling diode coupled and connected to the breaking part transferred; the key 18 of the key 12 of the control circuit horizontally its line. Keys 11 and 12 are connected to control buses 24 and 25.

Matrix switch works as follows.

To turn on one relay 10, on

It is necessary to transfer the control circuit key 11 along the vertical of the first column and the control circuit key 12 along the horizontal of the first row. For example, at node J at the intersection of the first column and the first row. Then, a control pulse is applied to control buses 24 and 25, the duration of which is

This should be no less than the response time of the JO. In this case, the switching node relay 10 will turn on, since its turn-on winding 13 will receive power through the bus 24 - the closing part of pin 18 of the first row - winding 13 - diode 15 - pin 17 of the first column - bus 25, -If the first column previously included relay 10 at switching nodes 4 and 7, they are disconnected, since their disconnecting windings 14 will receive power through the following circuits: Bus 24 - disconnecting part of contact J 8 of its row - diode 23 - winding JA - diode 16 - pin 17 of the first column - bus 25. If in the first line previously the JO relays were switched on in nodes 2 and 3 of switching, then they are switch off because their winding 14 disconnections will receive power through the following circuits: bus 24 - pin 22 of its column - diode 21 - winding 14 - diode J9-- contact 20 of the first row - bus 25,

If you relocate the key J J of the control circuit vertically of one column (e.g., the first) and the keys of the 12 control circuits horizontally across several. lines (for example, the first and second), then when the control pulse is applied to the control buses 24 and 25, the JO relays are triggered, which are located at the intersection of the first column with the first and second rows (at the J and 4 switching nodes), and the included JO relays are switched off in nodes 2,3,5,6 and 7 switching (if they were previously included).

If you relocate the control circuit keys J1 vertically of several columns (for example, the first and second) and the control circuit key 12 horizontally in one row (for example, the first), then when a control pulse is applied to the control buses 24 and 25, the relay 10 at the intersection of the first and second columns from the first row (at the switching nodes 1 and 2), and the switched on relays 10 are disconnected at the switching nodes 3,4,5,7 and 8 (if they were previously included).

If you relocate the control circuit keys 11 vertically on & many columns (for example, the first and second) and the control keys 12 on the horizontal line of several lines (for example, first and second), then when the control pulse is applied to the control buses 24 and 25, the relay 10 will operate located at the intersection of the first and second columns with the first and second rows (at switching nodes 1, 2, 4 and 5), and switched on relays at switching nodes 3,6,7 and 8 (if they were previously included) are turned off,

To disable all relays 10 that are in one column (for example, the first one), you need to relocate the control circuit key 11 along the vertical of the first column. Then, when a control pulse is applied to the buses 24 and 25, the relays 10 are disconnected at the switching nodes 1.4 and 7, since their disconnecting windings 14 are powered through the following circuits: bus 24 is the opening part of pin 18 of its own line — diode 23 - winding 14 — diode 16 — pin 17 of the first column — bus 25,

To turn off all relays 10 that are on the same line (for example, the first), you need to relocate the control circuit key 12 horizontally across the first row. Then, when the control is supplied, a pulse to the control buses 24 and 25 disconnects the relay 10 at the switching nodes 1,2 and 3, because their windings 14 disconnect the power supply via the circuits: bus 24 - pin 22 of its column - diode 21 - winding J4 diode 19 - pin 20 of the first row - bus 25,

Thus, the design of the matrix switch is simplified and the wire is saved by using two-winding polarized relays. In addition, the disconnection winding of each relay is powered both vertically (from the key of the control circuit of its column) and horizontally from the key of the control circuit of its row). Therefore, if the relay is located in a switching node at the intersection of a column and a row where one of the keys is turned on (either a column or a row), the coil of this relay is powered, if the relay is located in a switching node where both keys are turned on (as a column, and lines), then the winding of turning on this relay will receive power. This provides the ability to perform switching over a wide range.
