摘　　要：数据校验是为保证数据的完整性和正确性而进行的一种验证操作。CAN通信采用CRC校验作为一种重要的错误检测手段,是节点判断CAN帧信息的完整性并产生确认应答的依据。在现场总线通讯和控制的实际应用中,数据完整性校验是关重要的,像在汽车通讯中位置信息在传输过程中出现了错误,轻则可能造成车辆停车,重则可能导致车毁人亡。Data verification is a verification operation to ensure the integrity and correctness of data.CRC check is used in CAN communication as an important error detection method,which is the basis for nodes to judge the integrity of CAN frame information and generate confirmation response.In the field bus communication and control of the practical application,data integrity check is important,such as in the automobile communication location information in the transmission process error,light may cause the vehicle parking,heavy may lead to car destruction.
