Problems solved by technology

These problems are mainly manifested in: most interface systems adopt the traditional custom development mode, which can only meet the needs of the process control project itself, and it is difficult to meet the complex and changeable environmental requirements on site; the quality of the interface system is affected by the professional quality of the developers. The versatility, scalability and stability of the interface system cannot be effectively guaranteed; the tracking of the production process is bas

Abstract

The invention discloses an object linking and embedding for process control (OPC)-based general interface system and its control method. The method comprises storing configuration information related to the OPC-based general interface system in a database, carrying out a control process of a basic automation system and a process automation system related to the OPC-based general interface system on the basis of the related configuration information, modifying the related configuration information in the database and stopping the control process when the related configuration information needs to change, reading the modified related configuration information from the database, and restarting the control process, wherein the related configuration information comprises configuration information of a plurality of OPC servers, configuration information of data acquisition points and configuration information of event interfaces.

Description

technical field [0001] The invention belongs to the field of automation and process control, and in particular relates to an OPC-based general interface system and a control method thereof. Background technique [0002] With the increasing degree of factory automation, people have higher and higher requirements for information sharing, global monitoring, real-time scheduling and command of the entire production process. The requirements of modern industrial production for the control system are no longer limited to the automation of the general production process, but focus on whether the entire production process can run in the best state for a long time, and the goals pursued by the enterprise are no longer limited to the partial production process. Optimization, but the optimization of the overall goal. Therefore, the establishment of a production control system integrating management and control has become an urgent requirement for many factories. [0003] In the tradi...
