Industrial real-time database interface method

Abstract

The invention discloses an industrial real-time database interface method and belongs to the technical field of wireless network monitoring. The industrial real-time database interface method comprises an OPC (object linking and embedding for process control) technology of a real-time database and a DCS (distributed control system) interface, an interface realization method, OPC configuration of the real-time database, PI-API (Plant Information-Application Programming Interface) design and PI-SDK (Plant Information-Software Development Kit) interface design; process parameters are regulated in real time through optimization software, so that the optimal operation of a process is guaranteed; key process parameters influencing yield and quality are monitored; the quality data and profit of a product are subjected to online analysis through software for soft measurement and the like, so that the product problem can be discovered in time, the product yield can be increased, the product quality can be improved, and the economic benefit can be increased. The real-time database as a bridge for connecting a production process system with an enterprise comprehensive automation system plays an important role in integration of real-time control and management control, and an ideal platform is provided for development and application of the enterprise comprehensive automation system, so that informatization systems of enterprises can efficiently run in real time.

Description

technical field [0001] The invention relates to the technical field of wireless network monitoring, in particular to an industrial real-time database interface method. Background technique [0002] Since the appearance of the distributed control system (DCS), the distributed control system has been widely promoted in the field of industrial automatic control. Since the on-site control system (DCS / PLC / FCS) and various intelligent instruments and equipment usually come from different manufacturers, the communication between the equipment is very complicated, and application developers and computer hardware manufacturers need to write a large number of I / O driver, the same device needs to write drivers for different application software to be used by each application software, and the degree of software reuse is low; the interoperability of data between field devices and real-time databases is poor, and the communication is unstable; different manufacturers and The interfaces...
