Problems solved by technology

[0010] The purpose of the present invention is to overcome the defects of closed structure, fixed system function, inflexibility, poor compatibility, and high maintenance cost of the existing control technical solutions, and propose an open control method based on the LSOA architecture. The basic idea is to take service as the core , integrate the resources provided by each functional component into operable, standard-based services, so that they can be recombined and applied, and design a soft bus that can configure business processes online, which is an open system structure, can A control method featuring scalability, reconfigurability, online upgrade and maintenance, and strong fault-tolerant capability of application services

Embodiment

[0061] Such as figure 1 As shown, the open control system of the LSOA architecture based on the method of the present invention mainly includes six layers: application service layer, service support layer, transport layer, bus control layer, operating system layer and device layer. The bus control layer is the core, and its functional modules can be divided into information center, message processing module, scheduling module, security management module, fault tolerance module and business process configuration module, such as figure 2 shown. The bus control layer is responsible for processing the data exchange and mutual calls between the various modules of the entire control system, as well as the execution process of the entire closed-loop control; various data streams, including status, request, response and other information, need to be received by the bus control layer, and then by The bus control layer processes or forwards to related services for processing according...

Abstract

The invention relates to an open type control method based on a lightweight service-oriented architectures (LSOA) framework, which comprises the following steps: an application serving layer submits a request for registration service to a bus serving layer, configurates service process for the bus serving layer, and sends flow request massage to the bus control layer; the bus control layer carries out scheduling on the flow request according to the priority level of the flow request massage, processes the flow request and then sends the flow request to corresponding serving; the application serving receives the request massage and returns the result to the bus control layer after the appointed control logic is carried out; and the bus control layer returns the result back. The control method of the invention has open type system structure, is scalable and reconfigurable, can be updated and maintained on line, has strong application serving fault-tolerant capability and the like.

Description

technical field [0001] The present invention relates to an open structure control method, in particular to an open control method based on LSOA (Lightweight Service-Oriented Architectures, lightweight SOA) framework. Background technique [0002] Control system technology is undergoing a process of development from traditional closed control system to open control system. The open control system is a revolutionary leap in the field of mechanical manufacturing technology. Its hardware, software and bus specifications are all standard and open to the outside world, so that the control system can meet the requirements of modularization, standardization and networking. Therefore, the open control system is It is recognized that it will replace the traditional closed control system. At present, the open control system with a general architecture also has certain scalability and customization, meeting the basic requirements of openness and generality; but its configuration proces...
