摘要
CAN总线上的数据传输采用高效、可靠的差错检测方法——CRC校验算法。首先详细介绍了CRC校验算法的原理,并针对普通的CRC校验方法依然存在漏检事件的问题,设计了一种改进的CRC校验方法。经实验验证,该方法可以提高校验的检漏率,适用于可靠性要求较高的工业控制系统中。
This paper introduces the principle of the CRC Calibration algorithm in detail,and aiming at the problem of undetected events of ordinary CRC checking methods.An improved CRC checking method is designed in this paper.The experimental verification shows that this method can improve the reliability of calibration and is suitable for the industrial control system with high reliability requirement.
