Indoor Outdoor Position Tracking via IMES GPS Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional position management systems fail to track articles both indoors and outdoors effectively, as they rely on indoor messaging systems and lack flexibility in managing position information based on the type or importance level of the article.
Innovation Solution
A position management system that includes a detecting unit for movement detection, receiving units for radio wave communication, an acquiring unit for estimating position based on radio wave intensity, and a storing unit for associating position information with time, using IMES and GPS for indoor and outdoor tracking, respectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If indoor messaging system (IMES) is used for position management, then indoor position tracking is achieved, but outdoor position tracking fails
Solution Approach 1:
The position management system integrates multiple positioning functions by combining IMES for indoor positioning with GPS for outdoor positioning. The second device can automatically switch between these two positioning modes based on the environment, achieving universal position tracking across both indoor and outdoor scenarios.
Solution Approach 2:
The system introduces a server as an intermediary that receives position information from both IMES and GPS sources, processes the data, and provides unified position management. This mediator enables seamless transition between different positioning systems and handles the complexity of multi-source integration.
2Device complexity
If single server manages all position information, then system simplicity is maintained, but flexibility in managing different article types is lost
Solution Approach 1:
The system segments position information management by article characteristics. The server divides management responsibilities based on article types, importance levels, and movement patterns, allowing different positioning strategies to be applied to different articles while maintaining overall system coordination.
Solution Approach 2:
The server dynamically adjusts position management strategies based on article attributes and real-time conditions. It can flexibly change management approaches, switching between active tracking and passive recording modes, and adapting to different article priorities without requiring system reconfiguration.

Implementation Method 2
the second receiving unit receives a radio wave from GPS when the second device moves outdoors
Data Source
AI summary
A position management system includes a first receiving unit configured to receive a radio wave according to a predetermined wireless communication standard from a first device when the movement of a second device is detected; a second receiving unit configured to receive second position information including latitude and longitude information from an IMES transmitting device when the movement of the second device is detected; and an acquiring unit configured to measure an intensity of the received radio wave, estimate a position of the second device based on the intensity, and acquire first position information indicating the estimated position. The second receiving unit receives a radio wave from GPS when the second device moves outdoors where communication with the IMES transmitting device is not possible, and sets latitude and longitude information, which is measured based on the radio wave received from the GPS, as the second position information.
