Error detection and control of IIoT network based on CRC algorithm

摘要

In the process of computer network communication, there is usually the situation of measuring the instability of data transmission within a specified time, which is the problem of bit error rate (BER). In order to transmit information accurately and reliably, the communication is more secure and the signal is more stable. In general, the corresponding error control measures in the communication network will be taken. Cyclic redundancy check (CRC) algorithm is an effective method to detect network communication errors. In this paper, the application of cyclic redundancy check in computer network communication error detection and control is studied. The proposed CRC algorithm can reduce the error rate of the system by detecting and controlling the errors. In addition, we analyse the principle of CRC algorithm, check rules and the understanding of algorithm programming idea in detail. Finally, the application of CRC algorithm in computer network communication error detection and control is discussed, and the validity of CRC algorithm is verified by experiments.
