Abstract: With the rise of intelligent coal preparation plant construction, how to collect, store and share the data of the existing production system has become the primary problem to be solved. The research introduces the construction of standard data platform for coal preparation production process (Abbr. CPSDP) and its key technologies, includes the real-time collection of PLC data in the production centralized control system and the discrete data collection stored in the relational database, explains the storage rules of the data in the above two different collection methods, shares to different software demanders of intelligent construction through web API general interface. The construction of standard data platform for coal preparation production process will provide massive basic data of coal preparation standard for scientific researchers and production management workers of coal preparation plant, and provide services and data support for the establishment of big data platform of coal preparation information and the intellectualization of coal preparation process.
