Key technology and platform of intelligent mine basic information acquisition based on industrial Internet of things
Abstract
The data acquisition of intelligent mine is based on ubiquitous perception and cannot be separated from the basic technical support of industrial Internet of things and big data. This paper analyzes the current situation of coal mine automation and monitoring data acquisition technology and platform, that is, the lack of identity marks of the perception node, data not being shared, system maintenance difficulties, system software smokestack construction and data fusion difficulties. This paper proposes the process and key technologies of intelligent mine basic information acquisition based on industrial Internet of things, including low-power ubiquitous perception technology, perception node identification and data sharing technology, long-term maintenance-free technology, data hierarchical interaction and fusion technology, etc. On this basis, the structure and design concept of the intelligent mine basic information platform based on private cloud deployment is proposed. Only one set of distributed software platform based on microservice technology can solve the problem of the collection, classification and storage, interaction, fusion and analysis of all kinds of automation data in the entire mine, and realizes the linkage control with the control execution devices. Through the establishment of a unified technology and service system, including a unified technology architecture and technology stack, unified master data, unified data storage mechanism, unified data model, unified authority and user interface mode, it is ensured that multiple businesses integration can be realized under the same software platform. By establishing a unified data acquisition mode based on the Internet of things, that is, loading and adapting different protocol drivers, data acquisition by professional systems of different manufacturers is realized. Through the establishment of a unified data processing and storage mechanism, data fusion and release mechanism, it is able to provide consistent data sources for intelligent mines.
