Sharing platform applied to process flow industry process control system

Abstract

The invention relates to a sharing platform applied to process control systems in process industry, belonging to the technical field of sharing platforms of process control systems, comprising a process control system, a data exchanging machine, a model server, a report server, a data center server, and a message center server. The invention is characterized in that: the process control system is divided into a plurality of single function modules according to system functions; the data exchanging machine enables the data exchange between the PLC in an external system and the data center server; the model server provides model service to the process control system; the report server provides report service to the process control system; the data center server is the transfer station of data streams, which provides data sharing service to the model server, the report server and the process control system; the message center server is the transfer station for massage flows, which receives the messages of the other modules of the sharing platform and the process control system; all the messages can be seen on the user interface of the process control system. The invention has the advantages that: the development process of process control systems in process industry is simplified, and data service, message service, report service and model service are provided to the process control system.

Description

technical field [0001] The invention relates to the technical field of process control system sharing platform, and in particular provides a sharing platform applied to the process control system of process industry. technical background [0002] At present, the development process of the process industry process control system is as follows: the developer solves the data acquisition problem according to the on-site control system (mainly PLC control system, the current mainstream brand PLC mainly includes Omron, Siemens, Mitsubishi, Schneider, ABB, Siemens series.), Then collect customer requirements and define the functional modules of the process control system in order to meet the needs of different users for the process control system software. In this process, the common problems that developers need to solve are: [0003] 1. Solve the data acquisition problem of all PLCs as the data source of the process control system. [0004] 2. Data interaction between process c...
