System and method for realizing low-delay industrial real-time data acquisition

Abstract

The invention discloses a system for realizing low-delay industrial real-time data acquisition, and the system comprises an industrial data acquisition module which is in communication connection witha gateway machine. The gateway machine is in communication connection with an MQTT server; and the MQTT server is in communication access to a third party system. The method for realizing low-delay industrial real-time data acquisition specifically comprises the following steps: forwarding acquired real-time data through an industrial data acquisition gateway carried by a scada system, and setting gateway multi-path forwarding; according to a data protocol uploaded by the gateway machine, developing an independent receiving and analyzing service, and bypassing a scada overall data processingprocess to reduce the time delay; and after the data analysis is finished, enabling the data to be butted with the Internet of Things message platform and to be \ provided for a third party or an upper management system for use. The system and the method for realizing low-delay industrial real-time data acquisition are realized by utilizing an original scada system, so that the transformation costis low; and the data is reduced to 400-700ms from the original frequency of 3-5s, so that the use of various application scenarios of an enterprise can be basically met.

Description

technical field [0001] The invention relates to a data acquisition system and method, in particular to a low-delay industrial real-time data acquisition system and method, and belongs to the technical field of data acquisition systems and methods. Background technique [0002] In the process of informatization development, enterprises generally build scada systems to collect real-time data such as production site instruments, PLC, and DCS; however, scada systems involve data processing and storage in the process of real-time data collection, resulting in certain delays in data , cannot be used directly in real-time scenarios; another way to collect the data described above is the OPC.DA or OPC.UA protocol. Since most enterprises cannot fully consider the construction of the first-level network during the construction process, leading to PLC / DCS often operates in isolation by process. If this method is used for data collection, the scale of the network needs to be transforme...

[0002] In the process of informatization development, enterprises generally build scada systems to collect real-time data such as production site instruments, PLC, and DCS; however, scada systems involve data processing and storage in the process of real-time data collection, resulting in certain delays in data , cannot be used directly in real-time scenarios; another way to collect the data described above is the OPC.DA or OPC.UA protocol. Since most enterprises cannot fully consider the construction of the first-level network during the construction process, leading to PLC / DCS often operates in isolation by process. If this method is used for data collection, the scale of the network needs to be transformed and the investment cost is high.
