Problems solved by technology

[0007] 3. The SCADA system built in the form of a cluster cannot fully meet the scale of large, medium and small projects, especially micro projects (the whole system has only one node)
[0008] 4. In the process of engineering implementation and modeling, it is also necessary to pay attention to the deployment and operation model, not just focus on business modeling
[0009] 5. In the project configuration stage, it is necessary to configure the running location information of its related services. There is no way to achieve location-independent, which is not convenient for flexible deployment and flexible expansion during project implementation.

Embodiment 1

[0055] The present invention designed a distributed real -time data interaction method that has nothing to do with position, which can abandon the cluster system during runtime to remove centralized naming services; use business objects to carry business data operation methods, simplify configuration and implementation, can be used to carry out the implementation of the configuration. The business data of the entire business system is split flexibly, and the entire business system responsible for the entire business system can be distributed on various business objects. It can be flexibly expanded and updated. Method: The implementation of the business system implemented by the nodes that are more than one or more in the same network in the same network, including the following steps:

[0056] 1) Application service software running on this node issues data requests that need to run in this node;

[0057] 2) Intelligent perception service software running on this node forms a requ...

Embodiment 2

[0063] This embodiment is further optimized on the basis of the above embodiments. The same part of the example technology of the aforementioned embodiments will be repeated here. Furthermore is to better realize the present invention. The following setting method is specially adopted: Step 2) In the middle, the request to query the location of the business object is adopted.

Embodiment 3

[0065] 本实施例是在上述任一实施例的基础上进一步优化,与前述实施例技术相同部分在此将不再赘述,进一步的为更好地实现本发明,特别采用下述设置方式:所述业务The system includes at least one node of the network in the same network, and the application service software and intelligent sensing service software are deployed on the node.

Abstract

The invention discloses a position-independent distributed real-time data interaction method, which is realized by a business system formed by at least one node in the same network, and includes the following steps: application service software running on the node Send a data request that needs to run a business object that does not exist in the node; the intellisense service software running on this node accepts the data request and forms a request for querying the location of the business object and sends it out; the intellisense service software running on other nodes receives the query service The request for the location of the object determines whether the business object exists on its own node. If it exists, the intellisense service software of the node where the business object is located responds to the query request of the location of the business object and sends the request information to the node, and its intellisense service software responds. ; The application service software of this node establishes a real-time data channel with the application service software of the node where the business object is located to realize real-time data communication.

Description

Technical field [0001] The invention involves distributed systems, SCADA systems, data processing technology and other fields. Specifically, it is a distributed real -time data interaction method that has nothing to do with location. Background technique [0002] The distributed system is a software system built on the network, with high degree of internal agglomeration and transparency; in a distributed system, a set of independent computers showing a unified whole when it is displayed to the user, as if it is a system of a system Seeing it. Data collection and surveillance control system (SCADA system), which is a more common application system in the distributed real -time processing system, is a distributed real -time processing system with high performance requirements; SCADA engineering application project has a long implementation process and modified configuration modification Frequent operations, in the process of real -time engineering, with the continuous expansion of ...
