Description

one

The invention relates to the field of automation and computing technology can be used in the information display systems for various physical processes.

A matrix indicator is known which contains cells consisting of thyratrons and diode circuits And, row and column distributors and an element of quenching of thyratrons.

The proposed device is distinguished by the fact that in it the element of halogen and thyratrons is made in the form of a parallel transistor switch included in the aadic chain of thyratrons of Each line, and the control input of each key is connected with the first output of the column distributor and the output of the distributor , corresponds to the first line in which the key is located.

This may simplify the matrix indicator and increase its reliability.

Scheme 1 is presented: a device is given, in the drawing.

The device contains indication cells /, the element of thyratron 2 enrichment, the column 3 distributor, the row distributor 4, the waiting blocking generator 5.

The display cell is made on a thyratron 6, an anode resistor 7, a grid resistor 8, a trigger capacitor 9, a trigger resistor 10, and a diode: And circuit, which consists of diodes //, 12 and 73- / 5 resistors.

The element of thickening of tiratron 2 represents a parallel transistor switch and is completed on transistor 16 and resistors 17 - J9.

Scheme works as follows.

The incoming synchronization pulse selects the first row and the first column, resulting in positive pulses at the first outputs of the row distributor and the column distributor. The trapvistor 16 of the element of thyratron 2 enrichment opens, which shunts the anodic value of the Pitany thyratron of the first row and ha, sith them. Then, under the action of the pulses arriving at the input of the column distributor (nx by 20), the thyratrons of the first row are sequentially selected. In this case, the transistor 16 is locked by the action of the source cm, as the first. the output of the column distributor is now at zero potential and the anode feed of the first row thyratrons is being restored. For synchronization, a pulse is applied to the bus 21. Simultaneously with the successive selection of the first row thyratrons, a sequence of pulses arrives at the input of the waiting blocking generator (bus 22). The blocking generator generates a sequence of "flushes" that ignite the corresponding thyratrons of the first row. After selecting the first row thyratrons, the row dispenser switches to the next state, and the column dispenser switches to the "similar." There is a choice of the second line and the first column. The element of hashetia of the tiratrons of the second line is turned on And the tiratron of this line is quenched. Then, the second row thyratrons are selected with the ignition of the last block-generator ator according to the impulses arriving at its input (box 22). Then the row distributor goes to the next state, and the column distributor goes to the initial state, the third row thyratrons go off, and so on.

Subject invention

A matrix indicator containing indication cells consisting of thyratrons and diode circuits And, the distributors of the lad and the columns and the element of tiratron quenching, characterized in that, in order to (forgive the design and improve the reliability of the indicator, the element of quenching of tiratrons made in the form of a transistor switch included in the anode circuit of the thyratrons of each row, and the control input of each switch is connected to the input of the distribution of the columns and the output of the row distributor corresponding to the row in which dix key.
