Mobile-Assisted Power Control Mode Switching Without Physical Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control devices for electric power systems require physical interaction to change control modes, posing safety risks and inconvenience when engineers need to transition from local to remote control modes, especially in fault conditions.
Innovation Solution
A control device with a communication interface that allows setting control modes remotely via a mobile device, using authentication and biometric methods to ensure safety, and includes a mechanism for time-based criteria to prevent inadvertent mode changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical interaction is required to change control mode, then safety is improved, but ease of operation deteriorates
Solution Approach 1:
A mobile device serves as an intermediary between the engineer and the control device. The mobile device transmits data wirelessly to the control device, enabling mode changes without the engineer needing to physically interact with the control device. This resolves the contradiction by providing remote access capability while maintaining security through authenticated data transmission.
2Reliability
If physical presence is required at the control device, then safety is improved, but loss of time increases
Solution Approach 1:
The patent replaces the mechanical requirement of physical presence with a wireless data transmission system. The control device receives data from the mobile device via wireless communication, eliminating the need for the engineer to travel to and physically interact with the control device. This substitution of mechanical presence with electronic communication resolves the time loss while maintaining safety through authenticated remote access.

AI summary
A control device for at least one electric power system component comprises at least one control circuit, configured to be coupled to a communication interface and the at least one electric power system component. The at least one control circuit is further configured to receive data from the communication interface, set the control device to a local control mode based on the received data if a user of a mobile device is at a first location local to the control device, and set the control device to a remote control mode in response to a request of the user of the mobile device from a second location remote to the control device. A mobile device configured to interact with the control device is also provided.
