Embodiment Construction

[0059] The present invention will be further described below. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0060] The DCS communication loose coupling management method of the present invention, such as image 3 shown, including the following steps:

[0061] 1) Unified management of various communication types in the DCS distributed control system, forming a communication type library, which exists and is available in the form of XML or SQL database; the communication type library refers to figure 1 ;

[0062] 2) Unified management of various communication protocols and database connections of the DCS distributed control system, forming a protocol connection library, which exists in the form of XML or SQL database and is used for query; communication protocol and database connection library refer to figure 1 ;

[0063] 3) The communication m...

Abstract

The invention discloses a DCS communication loose coupling management method. A communication management server builds a DCS communication management middleware and re-defines a communication path; a communication management server side registers the communication path; receiving-transmitting equipment receives registration information via a communication proxy to perform instantiation; when starting, the receiving-transmitting equipment firstly inquiries whether a remote communication management server has update content via the communication proxy of the equipment, if the update content exists, a library update process is performed, delayed binding initialization is performed after instantiation again, if the update content does not exist, delayed binding initialization; an instance which has completed delayed binding is activated; a communication link is built for transmitting or receiving communication information. According to the method provided by the invention, resetting and debugging complexity degrees caused by modification and upgrade of the system are reduced, so that the communication process of the DCS is automatic, openness of the DCS system is kept and improved, and complexity of a heterogonous software and hardware platform of the distributed system is reduced.

Description

technical field [0001] The invention relates to a distributed control system DCS communication loose coupling management method, which belongs to the technical field of distributed system general communication. Background technique [0002] In the modern DCS distributed control system, as the data scale becomes larger and larger, and the network scale of the operation station and the control station increases, the communication network system, which is an important part of the DCS system, has an increasingly heavy network communication load; On the other hand, the network structure in the DCS communication network is becoming more and more complex, and there are more and more types of communication protocols, and the distributed real-time database and distributed historical database as the back-end of the scheduling layer, management layer and decision-making layer in the system , all rely on the mass communication gathered by the front-end control bus and operation bus. ...
