SU475621A1 - Device for the primary processing of messages - Google Patents

Description

The information in the five (six) -element code enters block 2 from block 14 or from the photo reader 13 through block 1. Block 2 selects the signs of the beginning of the header, the beginning of the text, the text kope, the transfer kope, forms the corresponding characters at the right time. seven (eight) -element code and issues them through the node 6 block transfer to the equipment 19 transfer dapnyh. The information symbols are switched by unit 2 to converter 3, then the converted characters are output via node 6 to external devices. In case of violation of a sequence of service characters, block 2 generates and outputs to the data transmission equipment the commapapia of the emergency text end. The control signals necessary for the operation of the data transmission equipment are generated and analyzed by the mode switching unit 5, which controls the operation cycles of the operation unit 2 when processing incoming and outgoing messages in accordance with the operation cycles of the data transmission equipment.

The information in the seven (eight) -element code comes from the aparatera 19 of the transfer of data to node 6, and then to analysis block 2 and the message format conversion, which highlights the characters of the "Beginning of the header," Beginning of the text, "The end of the text, forms the corresponding attributes in five (six) -leleptic code and gives them to the output unit 15 or through the unit 7 to the reperformer 16.

The information symbols are switched by the unit 2 into the converter 4, the analysis and conversion unit of message formats receives from the time sensor 8 signals of the current time code and, if necessary, inserts the corresponding combinations into the format of transmitted and received messages. In order to eliminate distortions caused by the possibility of changing the code during the sequential output of the combinations of hours and minutes, block 2 blocks the operation of time sensor 8 for a time until the output of these combinations ends.

Similarly, the time sensor 8 exchanges the signals of the current time and blocking code with the signaling unit 17.

The transmitted messages are output from block 2 to block 11 of the transfer documentation, and the headers of these messages with a processing time stamp are output to block 10 of the transfer registration.

The headers of the received messages with the processing time stamp are switched by block 2 to reception block 18, and it is possible to output full messages to this block.

When displaying information on external devices, unit 2 generates appropriate printing combinations that take into account the specifics of the operation of direct-printing devices. In addition to the automatic switching on and off of the reperforator, the block 7 interface with the reperformer controls the coasting of the punched tape in the reperformer between the messages for the convenience of separating the punched tapes with messages and their further use.

The exchange of information with external devices and at the junctions between the main conversion devices is carried out with a parity check. Instead of an erroneous combination, a special substitution combination is formed.

When the device for processing messages is working together with the address generation unit 12, the proposed device is able to convert the source number messages into messages containing one or more addresses and recipients in the header in accordance with the system requirements. Upon admission from the hardware

the transmission of additional messages containing a specific attribute and source address, unit 2 generates a response message - a receipt to this address.

Block 9 test control at admission

the signal from the external signaling device generates and issues in block 2 a short message containing the prizapak of the beginning of the header, control and end of the text. Block 2 converts this message as usual, but commutes it from the transmitting part to the transfer equipment, and to the receiving part. The original combinations before the transformation and the combinations that are twice transformed during transmission and reception go to the test control block for the elementwise comparison. In the event of a mismatch of combinations, the processing program stops and a fault signal is generated. For a more thorough check of the code conversion blocks, a control message containing all convertible combinations is entered from the photo reader or the input block.

Node 6 of block transfer divides the message into blocks of a certain length or limited by the combinations End of Text and End of Transfer. After the last combination is transmitted to the channel, the node 6 of block transfer transmits to the mode switching unit 5

signal that blocks further start of cycles. Transmission is resumed after receipt of an authorization signal from the data transmission apparatus 19. After receiving the last combination, the node 6 forms into the equipment

data transmission signal that must be transmitted to the system as a signal allowing further transmission. It is possible to transmit or receive a message without blocking.

The mode switching unit 5, in conjunction with a similar device at the opposite end, controls the operation of the transmission equipment, while providing data transfer capabilities with simultaneous transmission of analog information.
