チ制御方式に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a switch control system for large-scale switcher systems such as video signal switcher systems and audio switcher systems.
従来、この種のスイッチ制御方式では、列を渡って素材

、そのパルスを押釦のコモンに供給し、押釦を押した時
点に時分割パルスが到来することにより、押された押釦
に対応する素材を制御している。Conventionally, in this type of switch control method, multiple control lines are wired across rows for each material, and then rows A, B, etc.
and sequentially in the column direction, generates a time-division pulse indicating the column, supplies that pulse to the common of the push button, and the time-division pulse arrives at the time the push button is pressed, so it corresponds to the pressed push button. Controlling the material.

ルス発生器を備え、列ごとに時分割を行っているため、
発生器の故障又は出力回路の故障など１つの回路の故障
がシステム全体の被制御スイッチ回路に影響を及ぼすと
いう問題がある。Conventional switch control systems have complex time-division pulse generators that indicate columns, and time-division is performed for each column.
The problem is that a failure in one circuit, such as a generator failure or an output circuit failure, affects the controlled switch circuits of the entire system.

に分離するデータセレクタとを備える。The present invention provides a switch control method in which a controlled switch circuit is controlled by a push button switch operation signal outputted from a push button switch circuit having a plurality of rows of a plurality of push button switches, in which the push button switch operation signal indicates a row of the controlled switch circuits. a diode that branches into a column control signal and a material switching control signal that switches the material signal in the controlled switch circuit;
and a data selector that separates the material switching control signal for each column based on the column control signal.
次に、本発明の実施例について図面を参照して説明する
。Next, embodiments of the present invention will be described with reference to the drawings.
本発明の一実施例を示す図を参照すると、１はＡ列の押

イオード２は押釦スイッチ１の押釦スイッチ情報を列情
報４として取り出す。このダイオード２は同列の他の釦
が押された場合の情報の逆流を防止する。ダイオード３
は押釦スイッチ情報を素材切替情報６として取り出す。Referring to the figure showing one embodiment of the present invention, 1 is a push button switch in the A row, and 1' is a push button switch in the B row. The diode 2 takes out the push button switch information of the push button switch 1 as column information 4. This diode 2 prevents information from flowing backwards when other buttons in the same row are pressed. diode 3
extracts the push button switch information as material switching information 6.
このダイオード３は他の列の同じ素材釦が押された場合

報６の取り込みを禁止させる信号８を発生する。This diode 3 functions to prevent backflow when the same material button in another row is pressed. The material switching information 6 is unified into one line across each column. The data selector 7 uses the column information 4 to separate the material switching information 6 into material switching information for each column. The controlled switch circuit 10 is controlled by the controlled switch circuit control signal 9. The simultaneous operation prohibition circuit 5 constantly monitors the column information 4 of each column, and the column information 4 is
If more than one is entered, a signal 8 is generated to prohibit the data selector 7 from taking in the material switching information 6.
以上説明したように本発明によれば、素材切替情報の１
本化制御を採用することにより、システム全体の信頼性
を向上させることができる。As explained above, according to the present invention, one of the material switching information
By adopting this standardized control, the reliability of the entire system can be improved.
