Industrial equipment remote data acquisition and processing method and transmission method

Abstract

The invention discloses an acquisition and processing method for transmitting remote data of industrial equipment, which comprises the following steps: acquiring equipment state data obtained in a current acquisition period according to a preset data acquisition time interval; based on the current reference information, comparing each parameter in the current equipment state data with a corresponding parameter in the reference information, and integrating information of changed parameters to obtain changed parameter data; caching the generated change parameter data in a preset data transmission period comprising a plurality of data acquisition time intervals, and packaging the plurality of change parameter data to obtain corresponding equipment data; and carrying out lossless compression on the equipment data to obtain corresponding equipment transmission data, and sending the data to a server. Differential data transmission and data variable-speed acquisition modes are utilized, dataintegrity transmission is guaranteed, server pressure is reduced, and a multi-data and high-acquisition-frequency acquisition and transmission mode is achieved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a collection and processing method for transmitting remote data of industrial equipment and a transmission method for remote data of industrial equipment. Background technique [0002] At present, with the development of the industrial Internet, the remote monitoring of industrial equipment is becoming more and more popular, and the technology is becoming more and more mature. But at the same time, with the increasingly powerful functions of industrial equipment, the data collected for remote monitoring is increasing. Usually, for a single piece of industrial equipment, the number of parameter types that need to be transmitted to the server is generally more than 1000. Therefore, in order to ensure the real-time and integrity of the data, the requirements for the transmission method of the collected data are getting higher and higher. . [0003] At present, the collectio...

AI Technical Summary

Problems solved by technology

[0003] At present, the collection and transmission of remote monitoring data of industrial equipment has the following problems: First, the data collection frequency of some equipment still cannot reach the level of one second. Therefore, the collected data cannot meet the remote equipment failure analysis, or cannot To meet the needs of big data analysis, it is impossible to extract useful information, which can be used as a reference for product upgrading and optimization; second, some systems that can achieve second-level data collection, due to the increase in the number of parameter types of collected data, the amount of collected data is huge, and the data The transmission and storage have very high requirements on the server; third, at present, most of the remote collection is based on the Internet. Due to the instability of the network, if the network is unstable, the transmission is prone to congestion
