Abstract

Способ определения нарушений и исправления нарушенных кодов разрядов числа при кодировании «1 из 4», обеспечивающий передачу информации по каналу связи, который на передающей стороне содержит источник информации, кодирующее устройство и передатчик, а на приемной - приемник, устройство контроля и оконечное устройство, при этом:- на передающей стороне канала данные от источника информации в виде слов в двоичном коде поступают на кодирующее устройство, где проходят форматирование и далее передатчиком пересылаются по линии связи в приемную часть канала;- на приемной стороне канала данные, поступившие на приемник, пересылаются в устройство контроля, где осуществляется проверка принятой информации на отсутствие ошибок, а при обнаружении таковых их устранение (корректировка информации) и последующая передача в оконечное устройство, отличающийся тем, что в кодирующем устройстве информация, поступившая из источника в двоичном коде, преобразуется в код «1 из 4» с активным нулем, формируется в виде массива слов, который можно представить в виде массива слов, который можно представить в форме таблицы, содержащей Пстрок (слов), каждая из которых содержит Пчетверичных разрядов в коде «1 из 4», при этом одноименные четверичные разряды строк образуют Пвертикальных столбцов массива, у каждой строки и вертикального столбца формируется контрольный код (Kи соответственно К) путем последовательного суммирования четверичных разрядов строк и вертикальных столбцов без учета переноса, в устройстве контроля поступившая информация проверяется на соответствие коду «1 из 4» и контрольным кодам Kи Ки при обнаружении несоответствия (оA method for detecting violations and correcting violated codes of digits of a number when encoding “1 of 4”, which provides information transfer via a communication channel, which on the transmitting side contains a source of information, an encoding device and a transmitter, and on the receiving side, a receiver, a control device, and a terminal device, this: - on the transmitting side of the channel, data from the source of information in the form of words in binary code is sent to the encoding device, where it is formatted and then transmitted by the transmitter over the communication line to the receiving part of the channel; - on the receiving side of the channel, the data received by the receiver are sent to the monitoring device, where the received information is checked for errors, and if any are detected, they are eliminated (information is corrected) and then transmitted to the terminal device, characterized in that the encoder, the information received from the source in binary code is converted to code “1 of 4” with an active zero, is formed as an array of words, which can be represented as an array of words that can be represented in the form of a table containing Pstrok (words), each of which contains Quaternary digits in the code “1 of 4”, with the same quadruple digits of the rows forming the Vertical columns of the array, a control code is generated for each row and vertical column (Ki and K, respectively) by sequentially summing the four-digit bits of rows and vertical columns without taking into account the transfer, the received information in the control device is checked for compliance with the code “1 of 4” and the control codes Ki and Ki when a mismatch is detected (about

Claims

A method for detecting violations and correcting violated codes of digits of a number when encoding “1 of 4”, which provides information transfer via a communication channel, which on the transmitting side contains a source of information, an encoding device and a transmitter, and on the receiving side, a receiver, a control device, and a terminal device, this:

- on the transmitting side of the channel, data from the information source in the form of words in binary code is sent to the encoding device, where they are formatted and then sent by the transmitter over the communication line to the receiving part of the channel;

- on the receiving side of the channel, the data received by the receiver are sent to the monitoring device, where the received information is checked for errors, and if any are detected, they are eliminated (information is corrected) and then transmitted to the terminal device, characterized in that the information in the encoding device received from the source in binary code is converted to code “1 of 4” with an active zero, is formed as an array of words, which can be represented as an array of words, which can be represented in the form of blits containing P ₁ rows (words), each of which contains P ₂ four-digit bits in the “1 of 4” code, with the same four-digit bits of lines forming P ₂ vertical columns of the array, a control code is generated for each row and vertical column (K _r and, accordingly, K _c ) by sequentially summing the four-digit bits of rows and vertical columns without taking into account the transfer, the received information in the control device is checked for compliance with the code “1 of 4” and the control codes K _ri and K _vi and if a mismatch is detected ( errors), its nature and location in the array are determined, after which the information is corrected (eliminated) by the zero-code method, which is as follows: the contents of the faulty four-digit discharge are replaced by a zero value (0001), a control code is generated (K _ro and K _in ) taking into account the replacement made, the difference is determined

K _r -K _ro = ΔK _r or K _in -K _in = ΔK _in

and the zero code set earlier in the faulty discharge is replaced by ΔK _r (ΔK _in ).
