Edge Power Monitoring With Selective Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The management system for power consumption experiences increased communication costs due to high communication volumes between edge devices and server devices.
Innovation Solution
Implementing a system where edge devices store and transmit power information at predetermined intervals, with first power information transmitted upon request and second power information sent at the end of a target section, reducing unnecessary data transmission.

Engineering Contradiction Analysis
1Speed
If power consumption information is transmitted at every predetermined time interval, then the user can view real-time fluctuation status of power consumption, but the communication amount between edge device and server device increases
Solution Approach 1:
The edge device stores power consumption information in advance in two different storage units before transmission is needed. This preliminary storage allows the device to quickly retrieve and transmit appropriate data without needing to continuously communicate with the server, reducing communication overhead while maintaining real-time monitoring capability.
Solution Approach 2:
The invention divides power consumption information into two distinct types stored in separate storage units: real-time fluctuation data and cumulative consumption data. This segmentation allows selective transmission based on specific needs, reducing unnecessary communication while maintaining both real-time monitoring and cost tracking capabilities.
2Measurement precision
If first power information is transmitted frequently to maintain real-time monitoring, then the monitoring accuracy is improved, but communication costs increase
Solution Approach 1:
The system dynamically selects which type of power information to transmit based on the specific monitoring needs. The edge device can switch between transmitting real-time fluctuation data from the first storage unit and cumulative consumption data from the second storage unit, optimizing communication based on whether real-time accuracy or cost tracking is the priority.
Solution Approach 2:
Both types of power information are pre-calculated and stored before transmission is required. This eliminates the need for continuous real-time communication with the server, as the edge device can locally retrieve pre-prepared data, maintaining monitoring accuracy while significantly reducing communication costs.

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.
