Indoor Asset Mapping Using Markers and Floor Position Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current asset management systems fail to centrally manage assets both connected and disconnected from networks within a building, and require manual entry of position information during installation or relocation, making comprehensive management cumbersome.
Innovation Solution
A management system that includes sensors to detect objects and generate floor maps, markers to identify assets, and a database to associate asset information with positions, enabling the creation of asset management maps and management information, and determining network connections for comprehensive asset management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual entry of position information is required during installation or relocation, then asset management can be performed, but the operation becomes cumbersome and time-consuming
Solution Approach 1:
The system enables self-service by using sensors to automatically detect objects and obtain positional relationships, markers to automatically identify assets, and automated processes to register asset information in the database, eliminating the need for manual entry of position information during installation or relocation
Solution Approach 2:
The system performs preliminary action by pre-deploying markers on assets and sensors in the environment before asset installation or relocation occurs. When an asset is installed or moved, the sensor automatically detects the marker and registers the position information without requiring manual intervention at the moment of installation
2Reliability
If only network-connected assets are managed, then network-based asset information can be obtained, but assets not connected to the network cannot be comprehensively managed
Solution Approach 1:
The system achieves universality by implementing a dual-mode asset management approach that can manage both network-connected assets (through network diagnostic tools) and non-networked assets (through sensor-based detection and marker identification), making the system applicable to all assets regardless of their network connectivity status
Solution Approach 2:
The system introduces an intermediary approach by using physical markers attached to assets and sensors that detect these markers, serving as a mediator between the management system and assets that do not have network connection capabilities, thereby enabling comprehensive management of all assets

AI summary
A management system includes: a position sensor that obtains a positional relationship between itself and an object; a floor map generator that generates a floor map based on the position relationship; a self position calculator that calculates a self position; a marker identifier that identifies a marker; an asset information obtainer that obtains asset information related to an asset to which the marker is attached; an asset position calculator that calculates a position of the asset on the floor map based on the positional relationship, the self position, and a relative position of the marker; a database in which the floor map, the asset information, and the position information of the asset are associated with each other; and an asset management map generator that generates an asset management map based on the database.
