Data synchronization component of network relation database nodes of SCADA (Supervisory Control and Data Acquisition) system

Abstract

The invention discloses a data synchronization component of network relation database nodes of an SCADA (Supervisory Control and Data Acquisition) system. On the basis of the prior art, the data synchronization component designs and realizes new synchronization component Sycom and comprises synchronization support of a cross-relation database platform, low coupling with the SCADA system, support of data interaction of a network structure among a plurality of service nodes, setting of data sources and data terminals by a friendly mode of interface configuration, release of filtering conditions and detailing to recording level. The data synchronization component expresses the diversified service data replication requirement of a user by a simple and easy configuration interface and realizes more flexible work of synchronization, release and replication of data so as to adapt to the detailed market and the user requirement of an SCADA platform in more industries.

Description

technical field [0001] The invention relates to the professional technical field applied by the SCADA system platform, covering industrial control industries such as power monitoring, water conservancy monitoring, oil and gas chemical industry, rail transit, and coal mines that need to implement real-time data collection and environmental equipment monitoring services. At the same time, due to the extensive business requirements of background database storage, multi-node redundancy strategy, especially the active-standby redundancy mechanism, and the low coupling between the component design mode and the system, it can also be extended to professional and commercial applications with similar functional requirements. Background technique [0002] SCADA (Supervisory Control And Data Acquisition) system is data acquisition and monitoring control system. It can be widely used in many fields such as data acquisition, monitoring control and process control in power system, water c...

Problems solved by technology

However, the actual use of SCADA platform data requires more restrictive conditions, such as account requirements, fault recovery models, primary key requirements for data table establishment, server name restrictions, etc.; the configuration is cumbersome, and the more nodes, the higher the complexity; A lot of extra fields and dedicated data volume for synchronization are added to the data table, and the new data table is not handled well during the synchronization process; for special business data requirements, it is difficult to realize the free flow of data between multiple nodes

[0011] Shortcomings of the prior art: 1. The synchronization module designed and developed according to the manufacturer's own SCADA platform lacks the support of the cross-relational database platform, and is generally dedicated to the special database and special system; Separate storage of part of the business data specified by the user requires a lot of additional development and testing workload;

[0012]2. The use of a commercial relational database similar to publish-subscribe replication mechanism configuration is more complex and requires more additional disk space overhead; it is difficult to meet the special needs of specific nodes on the SCADA platform Data Replication Requirements
