摘要
针对电力系统中电能量数据传输的特点,研究并分析了数据库压缩算法RAY与周期压缩算法相结合的压缩算法。结合位图压缩方法,详细阐述了RAY和周期算法的压缩思想。最后给出了RAY-Period算法的压缩流程,并用C语言最终实现了这一算法。经过测试,能够对电能量数据进行有效压缩,有效减少了网络传输数据量,具有很大的实用价值。
Considering the features of electric energy data transmission in electric power system, the RAY-Period compression algorithm was researched and analyzed, which consisted of RAY compression algorithm in combination with period compression algorithm. Combining bitmap compression method, it expounded the compression theory of RAY algorithm and period algorithm respectively. At last, it presented the program flow of RAY-Period compression algorithm, and finally realized the algorithm by C language. The tests result shows that this algorithm could effectively compress electric energy data and could effectively reduce the network flux with great practical value.
