Solution Overview
Problem
Existing SCADA systems face delays and inflexibility in data transmission and control instruction reception due to the need for additional relays, which also hinder database building and processing speed.
Innovation Solution
An apparatus for relaying data transmission between a SCADA server and a host server, comprising a communications unit, an update unit, and a synchronization management unit, that enables quick and accurate data transmission, improves processing speed, and allows for a flexible database by utilizing a main and backup SCADA server with dual physical lines and real-time data backup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an additional relay (gateway) is used to transmit data from SCADA server to host server, then data transmission can be established, but data reception and control instruction reception are delayed
Solution Approach 1:
The patent extracts the data transmission function from the traditional gateway relay and implements it directly within the SCADA server through a communications unit. This eliminates the intermediate relay step that caused delays, allowing the SCADA server to directly transmit data to and receive control instructions from the host server without external gateway intervention.
Solution Approach 2:
The patent merges the data transmission functionality previously performed by an external gateway into the SCADA server itself. By combining the communications unit, update unit, and synchronization management unit within the SCADA server, the system eliminates the need for separate relay devices and reduces transmission delays while maintaining reliable data transmission.
2Reliability
If an additional relay (gateway) is used for data transmission, then communication can be established, but the system becomes less flexible in building databases and processing data
Solution Approach 1:
The patent extracts the data processing and database management functions from the gateway relay and implements them directly within the SCADA server. This allows the system to maintain communication reliability while gaining flexibility in database construction and data processing, as these functions are now integrated into the core SCADA server architecture rather than being constrained by external relay limitations.
Solution Approach 2:
The patent merges database building and data processing capabilities with the communication functions within the SCADA server. By integrating the communications unit, update unit, and synchronization management unit, the system achieves both reliable communication and enhanced adaptability for database construction and data processing operations.
3Stability of the object's composition
If traditional SCADA system architecture is used with gateway relay, then system stability is maintained, but data processing speed is reduced
Solution Approach 1:
The patent extracts the data processing operations from the traditional gateway relay architecture and implements them directly within the SCADA server. This eliminates the intermediate processing step that slowed down data handling while maintaining system stability through the integrated communications unit, update unit, and synchronization management unit that work together within the established system framework.
Solution Approach 2:
The patent merges high-speed data processing capabilities with system stability by integrating multiple functional units (communications unit, update unit, synchronization management unit) within the SCADA server. This combination allows the system to maintain its stable architecture while achieving faster data processing speeds through eliminated relay steps and direct processing pathways.

AI summary
Disclosed herein is an apparatus for relaying data transmission in a SCADA server. The apparatus includes: a communications unit configured to receive a data transmission request from the host server and transmit a target data request by the host server to the host server; a update unit configured to update event data corresponding to the target data among event data in the SCADA server and transmit the target data requested by the host server to the communications unit; and a synchronization management unit configured to synchronize the event data updated by the update unit with a backup SCADA server. Data transmission to a host server and control instruction reception from the host server in a SCADA system can be processed quickly and accurately.
