Description
Technical Field
The invention relates to the fields of distributed systems, SCADA systems, data processing technologies and the like, in particular to a distributed real-time data interaction method irrelevant to positions.
Background
The distributed system is a software system built on a network and has high cohesiveness and transparency; in a distributed system, a set of mutually independent computers appear to the user as a unified whole, as if it were a system. A data acquisition and monitoring control system (SCADA system), which is a common application system in a distributed real-time processing system and is a distributed real-time processing system with high performance requirements; the SCADA engineering application project has the advantages of long implementation process, frequent configuration modification operation, frequent system networking change along with continuous expansion of system scale in the real-time process of engineering, continuous increase of the number of running nodes formed during system running, and very high requirements on real-time performance and accuracy of real-time data interaction during the running of the whole distributed system.
In the current distributed system, the distributed real-time data interaction usually adopts an internet cluster mode, and the transmission of real-time data is carried out by combining the centralized naming service + message queue and other means; or centralized data storage runtime configuration information. The distributed real-time data interaction function realized by combining a cluster mode with a centralized time naming service + message queue and other means brings a lot of difficulties to the engineering application of the SCADA system; if the configuration of the cluster system is relatively very complex and the configuration content is more, professional IT technical personnel are needed to perform configuration or maintenance in the engineering implementation process and the operation and maintenance stage, and the technical requirements on the engineering implementation personnel and the operation and maintenance personnel are very high; in the engineering implementation process, along with the change and expansion of the system scale, when computer nodes are added and removed from the cluster system, more detailed configuration work needs to be done, which is inconvenient for the flexible expansion and modification of the system operation nodes, and the cluster system basically does not support the operation on a single node and does not meet the requirement of implementation on a micro project (when the whole system only has a single operation node); when the SCADA system runs, real-time data interaction is carried out, and running configuration information needs to be stored by means of centralized naming service or a centralized database; when each data service is deployed, the deployment position information of each data service needs to be deployed into a naming service; before carrying out real-time data interaction, an SCADA system needs to specify operation position information of a naming service, firstly, after acquiring an operation position of a corresponding data service from a global naming service, a real-time data channel is established for carrying out real-time data interaction; when the deployment operation position of each data service is changed or the operation position of the naming service is changed, a new operation position needs to be deployed to the global naming service, and the operation position of the naming service needs to be appointed again; when a project is implemented, particularly in a business modeling stage, not only a specific business system but also the deployment and operation positions of each service need to be concerned, and when the operation positions are modified or the deployment positions are transferred according to fault requirements, the configuration information of the relevant operation positions of the relevant system referring to the service needs to be modified and redeployed for operation, so that the project implementation and updating are inconvenient, and the flexible transplantation of the operation service and the flexible deployment of the service are inconvenient.
The main problems at present are:
1. the configuration of the SCADA system built based on the cluster + centralized naming service mode is very complex.
2. By adopting the SCADA system built by the cluster, professional IT technical personnel are needed for both project implementation and maintenance teams.
3. The SCADA system built in a cluster mode cannot completely meet all project scales of large, medium and small-sized projects, particularly miniature projects (the whole system has only one node).
4. In the process of engineering implementation and modeling, attention needs to be paid to deploying an operation model, and the operation model cannot be focused on business modeling.
5. In the engineering configuration stage, the operation position information of the related service needs to be configured, and no way is available for realizing independence of position, which is inconvenient for flexible deployment and flexible expansion when engineering is implemented.
6. When the operation nodes are newly added and changed and the service configuration is operated, a large amount of configuration is needed for the dependent service and the system, and the system needs to be redeployed and restarted most of the time.
