摘要
介绍了基于多路遥测数据采集系统在数据存储过程中的特点,提出了数据包的数据结构,并基于该数据包结构设计了低硬件复杂度的实时压缩算法。该数据压缩算法已成功应用于某舰船振动信号检测中,仿真及实际测试结果表明,该算法在满足数据处理精度要求的前提下,可获得较高的压缩因子。
This article introduced the characteristic of multichannel telemetered data acquiring system in the process of data storaging , proposed the data packet construction, and a kind of low hardware complex real-time compression algorithm is designed based on it.The algorithm has been uhilized in the signal examination of ships vibrates. Simulation result shows that this technology can meet requirement of muhi-channel real-time data compression, also achieve high compression ratio.
