运用Huffman编码处理江门中微子电子学数据

摘要

In order to meet the demand of Jiangmen Underground Neutrino Observatory (JUNO) experimental electronics system for large data transmission,Huffman coding is used to study the data processing of electronics.Real-time processing and compression of large amounts of data was achieved by combining the Huffman Coding with deviation calculation.The results of a large number of simulation show that the algorithm can reach compression rate of 25％ while maintain the original information;the algorithm has good stability and can maintain stable compression rate for different experimental data.This paper provides a reference scheme for data compression in JUNO.%为适应江门中微子实验电子学系统大量数据传输的需求,对将Huffman编码用于电子学的数据处理进行了研究.通过差值计算结合Huffman编码的方法,实现对大量数据的实时处理并进行压缩.大量数据仿真结果显示,该算法在保留原信息的同时压缩率可以达到25％;算法稳定性好,针对不同的实验数据均能保持较为稳定的压缩率.为江门中微子实验中的数据压缩提供了一种参考方案.
