Abstract
The paper studied the accuracy of transmission of vital messages for railway signalling and train controls systems using threshold fragmentation methods and antinoise coding. A scheme for the implementation of the transmission method of formalized messages with allocation of outer coding (generation of messages based on the principle of secret sharing) and internal coding (antinoise coding of fragments) is presented. The dependences of the probabilities of missing messages and receipt of a false report from the parameters of the fragmentation threshold scheme and antinoise coding with error detection and their correction are analyzed. It is shown that by changing the relation between the parameters of the external and internal encoding we can affect the relationship between the probability of missing a message and receiving a false report in accordance with the requirements made for the transmission of vital messages.
