Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for predicting future communication delays or data for controlling target devices often face a trade-off between processing load and prediction accuracy, where high accuracy can lead to increased processing loads.
Innovation Solution
An information processing device that calculates network delay time and determines the appropriate past data to use for predicting future data based on this delay, thereby balancing processing load and prediction accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If future data is predicted with high accuracy using more past data, then prediction accuracy is improved, but processing load increases
Solution Approach 1:
The patent dynamically adjusts the prediction period based on actual network delay measurements. The determination unit sets the prediction period to match the measured delay time, allowing the system to adapt the amount of past data used for prediction according to actual network conditions. This dynamic adjustment resolves the contradiction by optimizing the balance between prediction accuracy and processing load in real-time based on actual delay characteristics
Solution Approach 2:
The patent changes the parameter of prediction period based on measured delay time. By adjusting the prediction period parameter according to actual network delay, the system optimizes the trade-off between using sufficient past data for accurate prediction and limiting processing load. The prediction period is specifically set to correspond to the measured delay time, ensuring appropriate data selection
2Reliability
If network delay is large, then data transmission reliability is improved, but real-time control capability deteriorates
Solution Approach 1:
The patent performs preliminary prediction of future data before actual control actions are needed. By predicting future sensor data and target object states in advance using past data and measured delay characteristics, the system prepares control decisions proactively. This preliminary action compensates for network delay effects and maintains real-time control capability despite large delays
Solution Approach 2:
The patent creates a copy of future data through prediction rather than waiting for actual transmitted data. The prediction unit generates predicted future data that serves as a substitute for the delayed actual data, enabling control decisions to be made based on predicted rather than delayed information. This copying approach maintains control responsiveness despite network delay
Data Source
AI summary
An information processing device that performs communication via a network includes: a storage unit that stores a receiving unit that receives data acquired by a device; the data; and past data received by the receiving unit before the data; a calculating unit that calculates a delay time in the network; a determination unit that determines, based on the calculated delay time, one or more past data used for prediction of future data that is not received by the receiving unit from the past data stored in the storage unit; and a predicting unit that predicts the future data using the determined past data.
