Large-scale heterogeneous equipment integrated control method based on message middleware

Abstract

The invention discloses a large-scale heterogeneous equipment integrated control method based on message middleware. The method comprises the following steps of: abstracting all controlled objects inlarge-scale heterogeneous equipment into an equipment consistency access model which is provided with a uniform interface and is irrelevant in position; configuring the control system adopting the access model to comprise a server for providing equipment service, a database for providing database service and a client, and achieving the command and attribute read-write functions of multiple piecesof equipment through a publish / subscribe mechanism of the message-oriented middleware. The consistency access model and the control system matching the consistency access model are arranged, so that when the method is scientifically arranged in the control system, rapid integration and group monitoring of large-scale heterogeneous equipment can be conveniently and flexibly realized, and good coupling, expandability and maintainability are achieved, so that the requirement of long-period operation of the device is met.

Description

technical field [0001] The invention relates to the field of complex device control systems. More specifically, the present invention relates to a method for integrated control of large-scale heterogeneous equipment based on message middleware. Background technique [0002] The main task of the scientific device control system is system integration. There are a large number of instruments and meters and self-developed equipment in the control system, and it needs to meet complex control requirements such as experimental data transmission and scientific calculation. The control system has the characteristics of a wide variety of controlled equipment, complex communication protocols, large control scale, long operating cycle, and variable control requirements. The integrated control software is required to have good coupling, maintainability, and scalability to ensure scientific device control. The rapid development and simulation verification of the system ensures the effici...

Problems solved by technology

[0003] Traditional SCADA software is easy to use, but it is difficult to realize the rapid integration of various heterogeneous devices and complex control requirements; the distributed software framework directly based on object-oriented middleware can quickly complete the integration of the control system, but the coupling is strong and can be Poor reusability and difficult software upgrades; distributed software framework based on SOA architecture has good coupling, scalability and maintainability, but cannot meet the needs of large-scale equipment group control and monitoring

That is, none of the existing technologies can achieve integration
