Design of Multi-channel Telemetry Data Structure and Real-time Compression Algorithm
By analyzing the storage characteristic of data for multi-channel telemetry data acquisition system based on solid state recorder, the necessity of data compression is discussed in this paper, the disadvantage of present data structure in data compression is also described. Aiming at multi-channel data acquisition system, this paper introduces data packet structure, and a real-time compression algorithm for low complex hardware design is described based on it. Simulation result shows that this technology can meet requirement of multi-channel real-time data compression, also achieves high compression ratio and fast compression speed, possess great application value.
