SIGNAL ERROR DETECTION IN RAILROAD COMMUNICATION SYSTEM

A communication system (10) for a distributed locomotive power communications system for a railroad train having a lead locomotive (14) and one or more remote locomotives (12, 13). Messages are communicated over the system between the lead (14) and remote (12, 13) locomotives. Each communicated mess...

Beschreibung
Zusammenfassung:	A communication system (10) for a distributed locomotive power communications system for a railroad train having a lead locomotive (14) and one or more remote locomotives (12, 13). Messages are communicated over the system between the lead (14) and remote (12, 13) locomotives. Each communicated message includes information bits (41) and an error detection bits (42, 43, 44) for detecting errors in the information bits (41). The error detection bits (42, 43, 44) further comprise cyclic redundancy code words and parity bits formed according to the horizontal (43) or vertical (44) parity of the information bits (41) and the cyclic redundancy code words (42). L'invention concerne un système de communication (10) pour système de communications entre motrices réparties dans un train comportant une motrice de tête (14) et une ou plusieurs motrices distantes (12, 13). Des messages sont communiqués sur le système entre les motrices de tête (14) et distantes (12, 13). Chaque message communiqué comprend des bits d'information (41) et des bits de détection d'erreur (42, 43, 44) destinés à détecter des erreurs dans les bits d'information (41). Les bits de détection d'erreur (42, 43, 44) comprennent, en outre, des mots de code à redondance cyclique et des bits de parité formés selon la parité horizontale (43) ou verticale (44) des bits d'information (41) et des mots de code à redondance cyclique (42).
