FIELD: digital information recording. SUBSTANCE: monitored information is stored by on- board unit to magnetic carrier. This information is encoded as code without self-correction capability. When information is read, errors of second type could occur (signal which carries 1 is read, while signal which carries 0 is not). Sometimes such errors in read information is impossible to detect. Difference between adjacent measurements and transition matrices are used for detection of error in code information. EFFECT: increased reliability. |
