Remote distributed control system and distributed control method based on Internet

Abstract

The invention relates to a remote distributed control system and a distributed control method based on the Internet. The system comprises a remote operation station, a field control station and the Internet, wherein the remote operation station comprises a control strategy configuration software module, a database configuration software module, a man-machine interface configuration software module and a client end communication software module, the field control station comprises a local server, a server end communication software module, a control station and field equipment, and a client end and the server end communication software module are connected through the Internet. The method comprises the steps that: 1, control configuration is accomplished in the configuration software of the remote operation station; 2, data communication is established between the remote operation station and the field control station; 3, corresponding control logic configuration is carried out by the field control station, the field equipment is driven to operate, and real-time data is acquired and updated; and 4, real-time monitoring and debugging on control configuration are accomplished through the configuration software of the remote operation station. The control system and the control method have advantages of good control effects, high real-time performance and wide application scope.

Description

technical field [0001] The invention relates to the technical field of industrial automation control, in particular to an Internet-based remote distributed control system and method. Background technique [0002] With the development of computer network and automation technology, the network-based remote control system and distributed control system have gradually developed into intelligent control systems with complete functions. The research on the combination of remote control technology and distributed control system can integrate the advantages of the two technologies, so that the distributed control system can overcome geographical restrictions, realize remote monitoring and control, and greatly improve the application range and efficiency of the distributed control system. However, most of the research on the combination of these two technologies is still in the laboratory research stage, and there are few attempts in the field of practical application, and many resea...

AI Technical Summary

Problems solved by technology

However, most of the research on the combination of these two technologies is still in the laboratory research stage, and there are few attempts in the field of practical application, and many researches on actual control systems have only realized the function of remote monitoring, while remote control Few of the features involved

[0003] In recent years, the realization and improvement of the remote control function of the distributed control system has also received great attention, but its application effect is still very unsatisfactory

The existing technology mainly has the following deficiencies: (1) The remote operation station can only operate a small number of buttons and menus through the browser or client
