AI Technical Summary

Technical Problem

The amount of instrument data during transmission is large and the changes are small, resulting in low transmission efficiency and long time, making it difficult for the prior art to achieve fast and efficient data transmission.

Method used

A simple data compression algorithm is used to replace the original data by transmitting the difference between the original data and the minimum data of the same parameter, and recombining the difference data according to the maximum difference of different parameters before transmission, and decompressing the receiver through the reverse process.

Benefits of technology

On the premise of ensuring lossless data, greatly reduce the total amount of data to be sent, improve the data transmission speed, simplify the data compression method, and realize high-speed transmission.

Abstract

The invention relates to the field of instrument data compression and transmission, in particular to a data compression algorithm for high-speed transmission of instrument data. According to the method, due to the characteristic of small change of transmission data in a short time, the difference value between the transmission original data and the minimum value of the same parameter is used for replacing the transmission data so as to reduce the total data volume. In other words, it is assumed that i parameters exist, each parameter takes n rows of data as a packet, the minimum value of each parameter in the n rows is used as a parameter transmission data reference, and the maximum difference value digit of each original data and the minimum value of the parameter is used as the digit reference of the parameter when one packet of data is transmitted; only packet header information for illustrating the structure, the minimum value and the maximum occupation number of each parameter and difference value data are combined in an eight-bit one-byte mode according to the maximum occupation number in the to-be-transmitted data compression packet. According to the algorithm, the transmitted data volume can be greatly reduced on the premise that the data is lossless, and high-speed data transmission is ensured while the data compression method is simplified.
