Problems solved by technology
In addition, from a non-technical point of view, under considerations such as anti-technology monopoly, technology secrecy, and control security, medium and large industrial departments generally split industrial control systems into different supply conditions, and different suppliers carry out equipment installation and commissioning separately. further exacerbates the challenge of effectively managing data types in industrial control systems

Embodiment
[0043] see figure 1 , figure 1 is a schematic flowchart of a method for acquiring heterogeneous information based on feature mapping in an embodiment of the present invention.
[0044] like figure 1 As shown, a method for obtaining heterogeneous information based on feature mapping, the method includes:
[0045] S11: Collect raw data in various industrial control systems to obtain raw data information;
[0046] In the specific implementation process of the present invention, the collection of raw data in various industrial control systems to obtain raw data information includes: judging the collection method of the required collection of raw data, wherein the collection method includes contact Collection and non-contact collection; when it is judged that the collection method of the raw data to be collected is contact collection, the raw data of various industrial control systems are collected based on the contact method, and the raw data information is obtained. The raw da...

The invention discloses a heterogeneous information acquisition method and device based on feature mapping, and the method comprises the steps: collecting the original data in various types of industrial control systems, and obtaining the original data information; performing data dimension reduction processing on the original data information to obtain dimension-reduced original data information;performing data fusion processing on the original data information subjected to dimension reduction by utilizing a feature extraction mode to obtain fused data information; and inputting the fused data information into a fusion storage module for storage based on a time sequence. According to the embodiment of the invention, the storage and management of the original data are greatly simplified;unified fusion of different physical quantity dimension data structures can be realized based on dimensionless feature data; in addition, direct exposure of the original sensitive data is avoided whenthe data is outward.
Description
technical field [0001] The present invention relates to the technical field of industrial data acquisition, in particular to a method and device for acquiring heterogeneous information based on feature mapping. Background technique [0002] Industrial automation and informatization have enabled more and more industrial departments to realize the overall control of the production process through industrial control systems (such as ERP / MES / DCS / SCADA systems); on the other hand, affected by the product process, upstream and downstream supporting Affected by technical factors such as capabilities, industrial control systems often differ significantly during on-site implementation. Taking chemical industry control as an example, there are more than 200 types of common industrial field control buses, and the collected data involves more than 40 physical dimensions. From the perspective of the upstream and downstream of the chemical supply chain, there are at most 60 manufacturers...
