Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing positioning technologies face challenges in ensuring continuous high-precision positioning both indoors and outdoors due to restrictions in deploying UWB base stations, leading to positioning interruptions and reduced precision when transitioning between environments.
Innovation Solution
A positioning apparatus and server system that includes a UWB positioning module with tag and base station modes, allowing it to switch dynamically based on status conditions and indication signals to ensure continuous high-precision positioning by acting as a mobile base station or tag, and a positioning server that manages base station switching to maintain precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If UWB base station is deployed to ensure indoor high-precision positioning, then positioning precision is improved, but deployment is restricted by building environment and power supply factors
Solution Approach 1:
The patent applies the dynamics principle by enabling the positioning apparatus to dynamically switch between two operational modes: UWB base station mode for positioning others and UWB tag mode for being positioned. This dynamic mode switching allows the same device to adapt to different deployment scenarios, overcoming the limitation of fixed base station deployment restrictions. The apparatus can serve as a mobile base station in areas where fixed base stations cannot be deployed, thereby improving both positioning precision and deployment flexibility.
2Reliability
If redundant UWB base station is deployed to ensure positioning continuity during area transition, then positioning continuity is improved, but device complexity and deployment difficulty increase
Solution Approach 1:
The patent applies the universality principle by designing a positioning apparatus that can perform multiple functions: it can operate as a UWB base station to position tags, as a UWB tag to be positioned, or as a mobile base station to supplement fixed base stations. This multi-functionality eliminates the need for separate redundant base station deployments, as the same apparatus can adapt its role based on the positioning scenario, thereby maintaining positioning continuity without increasing deployment complexity.
Solution Approach 2:
The positioning apparatus performs self-service by automatically switching between base station and tag modes based on its operational status and environmental conditions. The apparatus monitors its own state and dynamically adjusts its function to ensure continuous positioning service, eliminating the need for manual configuration of redundant base stations and reducing deployment complexity while maintaining reliability.
3Adaptability or versatility
If positioning apparatus switches from UWB tag mode to UWB base station mode, then positioning service capability is improved, but switching control complexity increases
Solution Approach 1:
The patent applies the feedback principle by implementing an automatic mode switching mechanism that monitors the positioning apparatus's operational status and environmental conditions. The system uses feedback from these monitoring data to determine when mode switching is necessary and executes the switching automatically, reducing control complexity. The feedback loop ensures the apparatus switches to base station mode when it has sufficient positioning information to serve as a mobile base station, and switches to tag mode when it needs to be positioned itself, thereby improving service capability without excessive control complexity.
Data Source
AI summary
A positioning apparatus includes: a first positioning module configured to obtain location information of the positioning apparatus in real time; and an ultra-wide-band (UWB) positioning module configured to receive a positioning request message sent by a to-be-positioned tag, where the positioning request message includes identification information of the to-be-positioned tag. The UWB positioning module is further configured to determine, after receiving the positioning request message, whether the UWB positioning module is in a UWB base station mode. The UWB positioning module is further configured to perform, in the UWB base station mode, positioning measurement on the to-be-positioned tag based on the location information and the identification information.
