Power Management Server Logic for Mismatched Battery Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electric power management systems, information received through different communication paths can experience displacements in receiving timing and received contents due to varying reliability, leading to potential inaccuracies in electric power control.
Innovation Solution
The system includes a server with a communication apparatus that performs communication through multiple paths and a control apparatus that executes electric power control. The control apparatus receives data from both paths and uses the more reliable data for control when transmission times and data contents differ, ensuring accurate control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If communication is performed through multiple communication paths, then communication reliability is improved, but information consistency deteriorates due to timing displacements
Solution Approach 1:
The control apparatus performs preliminary comparison of transmission timestamps from multiple communication paths before executing electric power control. By checking whether the timestamps coincide in advance, the system determines which data to use, preventing timing displacement issues from affecting control accuracy.
2Adaptability or versatility
If data from the first communication path is used when timestamps differ, then communication flexibility is maintained, but control accuracy deteriorates
Solution Approach 1:
The control apparatus introduces an intermediary judgment mechanism that compares transmission timestamps as an intermediate step between receiving data from multiple communication paths and executing electric power control. This intermediary check ensures that only synchronized data is used, maintaining control accuracy while preserving communication flexibility.
3Manufacturing precision
If data from the transmission facility is prioritized, then control accuracy is improved, but system complexity increases
Solution Approach 1:
The control apparatus changes the evaluation parameter from data content to transmission timestamp for determining which communication path data to use. By comparing timestamps rather than analyzing data contents, the system simplifies the decision-making process while maintaining control accuracy through timestamp-based synchronization.

AI summary
A management server executes processing including a step (S302) of storing first data when receiving the first data via a DCM (YES in S300), a step (S308) of storing second data when receiving the second data via an indoor controller (YES in S304), a step (S314) of executing electric power control using the second data when the latest transmission times of both data do not coincide with each other (NO in S308), a step (S316) of determining that abnormality occurs on a system when the transmission times coincide with each other (YES in S308) and pieces of battery information do not coincide with each other (NO in S310), and a step (S312) of executing the electric power control using the first data and the second data when the pieces of battery information coincide with each other (YES in S310).
