Data preprocessing and compression method and system for intelligent edge fusion terminal equipment

The method comprises the following steps: acquiring message data of the intelligent edge fusion terminal equipment, processing original message data of different protocol texts according to an interaction protocol, judging a protocol type, and judging whether a key value dictionary should be generated or not according to the protocol type; performing different preprocessing operations according to different judgment results; and the digital receiving end receives the preprocessed compressed data, performs judgment, verification and decompression operations, judges whether the abbreviation key value needs to be replaced by the original long key value of the protocol or not, and performs an operation of recovering the original message protocol data in a classified manner according to a judgment result. The problems that the wireless network communication cost is too high and the terminal internal communication resource consumption is too large due to mass data interaction and a collaborative linkage mechanism o
