Database State Management in Energy Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional energy management systems face limitations in client access to database state information, making it difficult for clients to monitor and manage database operations, detect errors, and receive timely notifications about database issues, leading to inefficiencies and potential system failures.
Innovation Solution
The proposed solution involves an energy management system with a state transfer unit that directly communicates with clients to provide creation, deletion, and error information of the database, allowing for real-time monitoring and error handling, reducing the need for clients to access the server directly and minimizing system overload.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the control unit directly manages the database without state transfer, then the system structure is simpler, but the client cannot monitor database state and errors in real-time
Solution Approach 1:
A state transfer unit is introduced as an intermediary component between the control unit and the client. This mediator automatically transfers database state information, creation/deletion notifications, and error messages to the client, eliminating direct client-server database access while providing real-time monitoring capabilities.
2Loss of information
If the client accesses the server directly to monitor database state, then the client can obtain database information, but the system requires more complex access mechanisms and increases server load
Solution Approach 1:
The state transfer unit automatically monitors database state changes, creation operations, deletion operations, and errors, then pushes this information to clients without requiring clients to actively query the server. This self-service approach reduces server load and simplifies client access mechanisms.
3Reliability
If the system provides comprehensive database monitoring to clients, then error detection improves, but the system overhead and communication load increase
Solution Approach 1:
The state transfer unit operates periodically, transferring database state information and error notifications only when changes occur or at scheduled intervals, rather than maintaining continuous real-time communication streams. This periodic action reduces system overhead while maintaining reliable error detection capabilities.
