SU809617A2 - Device for automatic switching and interfacing of alpha-numeric information sources and receivers with data transmission apparatus - Google Patents

Description

one

This invention relates to communications and can be used in automated systems for transmitting and processing imaging.

According to the main auth. 451205, a device is known for automatic switching of interfaces of sources and receivers of alphanumeric information with data transmission equipment, comprising a matching unit, a control unit and a way of addressing, an address analysis unit, an information distribution unit, an OR gate and the corresponding connection 1.

However, the known device provides a relatively low switching accuracy.

The purpose of the invention is to improve the accuracy of switching.

This goal is achieved by the fact that character counters are entered into the device, the outputs of which are connected to the inputs of the control unit and the formation of addresses, the inputs of the character counters are connected to the corresponding inputs and buffer registers and a signal is received from n information sources.

The drawing shows a structural electrical circuit of the proposed device.

The device for automatic commutation and interfacing of sources and receivers of alphanumeric information with data transmission equipment contains a matching unit 1, a unit 2 for controlling and generating addresses, a unit for 3 points, a unit

4 information distribution, buffer registers 5, a logical element OR b and counters of 7 characters.

The device works as follows.

The information to be transmitted from n sources of alphanumeric information (not shown in the drawing), together with synchronization (clock) pulses, is fed to the inputs of the buffer registers 5 and is accumulated. At the same time, counters 7 count the number of accumulated characters or bits and, when filling buffer registers 5, issue processing requests for block 2. The latter ensures priority processing of incoming requests and outputs into buffer registers

5 series of shear pulses that read the accumulated iM0
