Edge Power Monitoring With Request-Based Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The communication amount between an edge device and a server device in power consumption management systems is high, leading to increased communication costs.
Innovation Solution
Implementing a management system with an edge device that stores power consumption data at predetermined intervals and transmits it at specific times, reducing the frequency of data transmission by only sending data when requested by the server device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the edge device transmits power consumption information frequently to the server device, then the server device can display real-time power consumption status, but the communication amount between the edge device and server device increases
Solution Approach 1:
The edge device transmits first power information at predetermined time intervals during the target section, rather than continuously. This periodic transmission maintains monitoring capability while reducing communication frequency and data volume compared to continuous transmission.
Solution Approach 2:
The edge device stores first power information locally at predetermined intervals during the target section before transmission. This preliminary storage allows the device to accumulate data efficiently and transmit in batches, reducing the frequency of communication interactions with the server.
2Loss of information
If the edge device stores and transmits all power consumption data continuously, then complete power consumption information is available, but communication costs increase
Solution Approach 1:
The power consumption information is segmented into two types: first power information (intermediate measurements during target section) and second power information (final cumulative measurement at target section end). This segmentation allows selective transmission based on server requests, reducing unnecessary communication while maintaining information completeness.
Solution Approach 2:
The edge device transmits first power information at predetermined intervals rather than continuously, and transmits second power information at the end of the target section. This periodic transmission schedule reduces communication frequency and costs while ensuring complete power consumption data is eventually available to the server.

AI summary
In a management system that manages power consumption, the communication amount between the edge device and the server device is reduced. A management system configured to manage power consumption, includes an edge device; and a server device, wherein the edge device includes a first storage unit configured to store, at every predetermined time interval, first power information based on a power consumption amount from when a target section starts; a second storage unit configured to store, when the target section ends, second power information based on a power consumption amount from when the target section starts to when the target section ends; and a first control unit configured to transmit the first power information in response to receiving a request from the server device, and to transmit the second power information at a predetermined timing.
