Electronic equipment real-time monitoring system design based on Huffman compression principle

More and more state variables in the case, the filter state variables, and identify operating modes means that the state collect and spend a lot of computing time, which lost control of real-time. This article will focus on one kind of high-frequency signal conversion equipment, work characteristics and work processes, using NI CompactRIO systems to set up equipment operating status monitoring system hardware, Requirements for equipment, the equipment failure, in the shortest possible time, alarm, we are monitoring the signals Huffman coding, in this based on pattern recognition, and compares relevant results. Compression algorithm used to retain equipment operation to the maximum extent of information processing while greatly reducing the time, the actual running results show that the method is feasible and has good application prospect.
