Embodiment 1

[0023] as attached figure 1 As shown, a physical information system data compression transmission method using a sliding window cache in this embodiment includes the following steps:

[0024] (1) In the physical information system, there will be many types of data transmission, among which the digital system is mainly the original uncompressed binary data stream.

[0025] (2) For the binary data stream, according to the size of the network packet or the requirements of the transmission unit, it is divided into independent block sizes such as 1024Byte, 4KByte or 16KByte.

[0026] (3) For each block, find all the symbols that appear in it, or repeat the sequence of symbols to form a set of symbols that may appear.

[0027] (4) Find a new binary representation for each symbol such that common symbols use few bits and uncommon symbols use more bits. The specific process is:

[0028] i. Starting from the current compression position, examine the unencoded data, and try to find t...

Abstract

The invention relates to a data transmission method of a physical information system, and in particular to a physical information system data compression transmission method using a sliding window cache. By aiming at a problem that the physical information system has a large amount of data to be transmitted, a data compression transmission method based on sliding window cache compression is provided, and when data is transmitted in the physical information system, a data flow has a large possibility of occurring repetitions. When one repetition occurs, a short code can take place of a repeated sequence. Such repetition is scanned by a compression program, and codes are generated to take place of repeated sequences at the same time. With the passage of time, the codes can be reused to capture a new sequence. A decompression program can deduce a current mapping in the codes and an original data sequence. The physical information system data compression transmission method using the sliding window cache, which is provided by the invention, can largely shorten data matching compression time so as to improve data compression transmission speed.

Description

technical field [0001] The invention relates to a data transmission method of a physical information system, in particular to a data compression transmission method of a physical information system using a sliding window cache. Background technique [0002] As the unity of computing process and physical process, physical information system is a next-generation intelligent system integrating computing, communication and control. Cyber-physical systems interact with physical processes through human-computer interaction interfaces, and use cyberspace to manipulate a physical entity in a remote, reliable, real-time, secure, and collaborative manner. The physical information system includes system engineering such as environmental perception, embedded computing, network communication and network control that will be ubiquitous in the future, so that the physical system has the functions of computing, communication, precise control, remote collaboration and autonomy. It focuses o...
