Automatic locomotive signalization system modification with weight-based sum codes

摘要

The features of weight-based sum codes for error detection in channel are discussed in this article. These features are acceptable for modification remote railway controlling systems such as locomotive signalization. In this article proposed the investigation for different coding modification algorithms, made an analysis of noise-immune properties when the modified Bauer code was replaced to modulo weight-code. Article includes deep analysis of all possible false transitions for code combinations in the data transmission channel are performed. The obtained methods for modifying the software modules of data encryption and decryption allowed to expand the system's accuracy by 4 times from 256 commands to 1024, meeting all the security requirements for data transmission.
