循环冗余码校验英文名称为Cyclical Redundancy Check，简称CRC。它是利用除法及余数的原理来作错误侦测（Error Detecting）的。实际应用时，发送装置计算出CRC值并随数据一同发送给接收装置，接收装置对收到的数据重新计算CRC并与收到的CRC相比较，若两个CRC值不同，则说明数据通讯出现错误。
根据应用环境与习惯的不同，CRC又可分为以下几种标准：
①CRC-12码；
②CRC-16码； https://blog.youkuaiyun.com/fairy_study/article/details/5638019https://blog.youkuaiyun.com/fairy_study/article/details/5638019fairy_studyMon, 31 May 2010 22:47:00 +08001.调制解调器的AT命令。
