Dual-Frequency Network Operation Data Reporting for Abnormality Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data collection and reporting modes between network devices and control devices face issues of high resource consumption and communication pressure when data is reported at high frequency, and difficulty in analyzing abnormalities when reported at low frequency.
Innovation Solution
A network device collects data at two frequencies, one high and one low, and sends data at the low frequency until an abnormality is detected, then sends a data set including high-frequency data before the abnormality to a control device for detailed analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If network operation data is reported at high frequency, then the control device can analyze abnormalities in detail, but resource consumption and communication pressure increase significantly
Solution Approach 1:
The patent implements dynamic data reporting by adjusting the reporting frequency based on network conditions. During normal operation, data is reported at low frequency to save resources. When abnormalities are detected, the system dynamically switches to high-frequency reporting to enable detailed analysis, thus resolving the contradiction between measurement precision and energy consumption
Solution Approach 2:
The system changes the reporting frequency parameter from a fixed value to a variable that adapts based on network status. By monitoring indicators such as error rates or traffic patterns, the system adjusts the reporting frequency to maintain adequate abnormality detection capability while minimizing overall resource consumption
2Use of energy by moving object
If network operation data is reported at low frequency, then resource consumption and communication pressure are reduced, but the control device cannot analyze abnormalities effectively
Solution Approach 1:
The system performs preliminary monitoring at low frequency to detect abnormal conditions. Once an anomaly is detected, high-frequency data collection is activated in advance to gather sufficient data for detailed analysis, ensuring that the control device has the necessary information to effectively analyze abnormalities without maintaining continuously high resource consumption
3Loss of information
If data is reported continuously at high frequency, then complete abnormality information is available, but communication pressure between network device and control device becomes heavy
Solution Approach 1:
The communication system dynamically adjusts data transmission frequency based on detected abnormality conditions. During normal operation, transmission occurs at low frequency to minimize communication pressure. When abnormalities are detected, the system switches to high-frequency transmission to ensure complete abnormality information is available for analysis
4Object-generated harmful factors
If data is reported at low frequency, then communication pressure is relieved, but the control device lacks sufficient data to determine abnormality causes
Solution Approach 1:
The system performs preliminary detection at low frequency to identify abnormal conditions. Upon detection, it activates high-frequency data collection and transmission to gather sufficient information about the abnormality cause, ensuring that the control device receives complete diagnostic data without maintaining continuously high communication pressure

AI summary
A data management method includes obtaining, by a network device, first network operation data collected at a first frequency and second network operation data collected at a second frequency higher than the first frequency. The data management method also includes sending, by the network device to a control device, the first network operation data. The data management method further includes, in response to an abnormality occurring in the first network operation data or the second network operation data, sending, by the network device, third network operation data to the control device. The third network operation data includes network operation data collected at the first frequency or the second frequency before a moment of the abnormality.
