Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current SCADA systems face latency and interoperability issues, as well as increased costs due to the lack of direct inter-domain communication between SCADA and wireless service provider domains, which hinders efficient data transfer between SCADA devices and AMI devices.
Innovation Solution
A SCADA gateway processor performs protocol conversion to facilitate direct data transfer between SCADA devices and AMI devices via a packet data network gateway and wireless communications network, bypassing the need for intermediate communications through SCADA control centers or enterprise domains.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If data transfer goes through intermediate systems (SCADA control centers or enterprise domains), then system compatibility and routing are maintained, but latency increases and communication efficiency decreases
Solution Approach 1:
The patent extracts and removes the intermediate SCADA control center and enterprise domain systems from the communication path between AMI devices and SCADA devices. By establishing a direct communication channel through the gateway, the data transfer speed improves while eliminating the latency introduced by multiple intermediate routing steps.
Solution Approach 2:
The SCADA gateway acts as a mediator that enables direct communication between AMI devices and SCADA devices without requiring intermediate SCADA control centers or enterprise domains. The gateway performs protocol conversion and facilitates direct data transfer, reducing latency while maintaining system compatibility.
2Loss of time
If direct communication between SCADA and wireless service provider domains is established, then latency is reduced and efficiency improved, but interoperability challenges increase
Solution Approach 1:
The SCADA gateway serves as an intermediary that performs protocol conversion between different communication protocols used by SCADA devices and AMI devices. This enables direct communication with reduced latency while maintaining protocol interoperability through the gateway's translation capabilities.
Solution Approach 2:
The gateway changes protocol parameters and formats to enable compatibility between SCADA and AMI devices. By transforming data packets from one protocol format to another, the system achieves direct communication with reduced latency while maintaining adaptability across different device types.
3Adaptability or versatility
If intermediate systems are used for data transfer, then protocol compatibility is maintained, but operational costs increase
Solution Approach 1:
The patent removes intermediate SCADA control centers and enterprise domain systems from the communication path, eliminating the operational costs associated with these intermediate systems. The SCADA gateway maintains protocol compatibility while reducing operational expenses by enabling direct communication.
4Adaptability or versatility
If protocol conversion is performed at intermediate systems, then interoperability is achieved, but communication efficiency and speed decrease
Solution Approach 1:
The SCADA gateway acts as a dedicated intermediary that performs protocol conversion directly at the communication interface between AMI and SCADA devices. This eliminates the need for multiple intermediate systems, maintaining interoperability while improving data transfer efficiency and speed through direct communication.
Data Source
AI summary
Transfer of data between at least one supervisory control and data acquisition (SCADA) device and an advanced metering infrastructure (AMI) device via a wireless communication network is facilitated. The data is used for monitoring and/or controlling the AMI device. A protocol conversion of the data is performed to facilitate transfer of the data between the SCADA device and the AMI device as data packets via a packet data network gateway and a wireless communications network.
