Header Check Sequence(HCS)

用法例句

In this paper,based on the principle of CRC and even parity,according to the protocol TCN(Train Communication Network),a 8-bit check sequence composed of a 7-bit CRC and a 1-bit even parity is designed in MVB,which greatly enhances its error detecting capability and reliability during the data transmission due to its duplication check.

分析了目前国内外多功能车辆总线的发展状况及自主研制MVB总线控制器及MVB网络接口卡对于我国轨道交通的现实意义,介绍了基于CRC循环冗余校验和偶校验的基本原理,并根据TCN协议,在MVB总线中设计了一个由7位CRC校验码和1位偶校验位构成的具有双重校验的8位校验序列,大大提高了数据传输中的检错能力与可靠性。
