Information Processing Apparatus for Dynamic Radio Quiet Zone Estimation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile object control systems face challenges in efficiently managing radio quiet zones, where signal propagation is deteriorated by obstacles, leading to unreliable control signal reception and potential operational disruptions, especially in dynamic environments like factories with changing obstacle arrangements.
Innovation Solution
An information processing apparatus that acquires and compares data on the mobile object's position and received signal power at different times to estimate the propagation environment, allowing for the selection of optimal routes that avoid or pass through radio quiet zones, thereby improving signal reception and operational stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile object moves along a route that avoids the radio quiet zone, then the signal reception reliability is improved, but the movement time increases and productivity decreases
Solution Approach 1:
The patent applies dynamics by making the route selection adaptive rather than static. The control device dynamically adjusts the mobile object's route based on real-time changes in obstacle arrangements. When obstacles are removed and radio quiet zones are eliminated, the system automatically updates the route to optimize both signal reception and movement efficiency, resolving the contradiction between reliability and productivity.
2Reliability
If the propagation environment is monitored in real-time to detect radio quiet zones, then the signal reception reliability is improved, but the system complexity increases
Solution Approach 1:
The patent implements feedback by having the control device acquire updated data on obstacle arrangements and detect changes in the propagation environment. The system continuously monitors the space, compares current obstacle positions with stored data, and adjusts routes based on detected changes. This feedback mechanism enables reliable signal reception monitoring without requiring complex dedicated detection hardware.
Solution Approach 2:
The patent uses the mobile object itself as an intermediary to detect propagation environment changes. Instead of deploying separate detection systems, the mobile object's position data and the control device's obstacle arrangement data serve as intermediaries to infer radio quiet zone locations, simplifying the overall system while maintaining reliability.
3Productivity
If the route is optimized to pass through areas with improved signal propagation, then the productivity increases, but the risk of signal loss increases when obstacles are present
Solution Approach 1:
The patent resolves this contradiction through dynamic route optimization. The control device stores initial obstacle arrangement data and compares it with updated data to detect changes in the propagation environment. When obstacles are removed and signal propagation improves in previously problematic areas, the system dynamically adjusts the route to utilize these improved areas, maximizing productivity while maintaining reliability through continuous environmental assessment.
