Lighthouse Tracking Base Station Switching for Extended Range
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The lighthouse tracking technology has a limited tracking range due to the inability to simultaneously receive signals from two secondary base stations, restricting the movement space of users in virtual reality environments.
Innovation Solution
A control apparatus and method that switches between secondary base stations by determining the movement of a trackable apparatus within a common coverage area, allowing only one secondary base station to operate at a time, thereby extending the tracking range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If two secondary base stations operate simultaneously in lighthouse tracking technology, then the tracking accuracy is improved, but the tracking range is limited
Solution Approach 1:
The system dynamically switches between different secondary base stations based on the trackable apparatus's position. The control apparatus determines which secondary base station should be active by analyzing signals from multiple base stations, enabling the system to adapt to changing spatial conditions and extend the effective tracking range while maintaining accuracy.
Solution Approach 2:
The system employs periodic switching between secondary base stations in a controlled manner. By alternately activating different secondary base stations according to a predetermined sequence and timing, the system ensures continuous tracking coverage across a larger area while maintaining the precision benefits of having multiple base stations available.
2Area of stationary object
If multiple secondary base stations are activated simultaneously, then the coverage area is extended, but the system complexity increases
Solution Approach 1:
The invention extracts and separates the control function from the base station operation. A dedicated control apparatus is introduced to manage the switching between secondary base stations, thereby simplifying the overall system architecture by centralizing the decision-making logic and reducing the complexity at each individual base station.
Solution Approach 2:
The control apparatus serves as an intermediary between multiple secondary base stations and the trackable apparatus. It receives signals from various base stations, processes the information to determine optimal switching timing, and coordinates the activation/deactivation of secondary base stations, thereby managing system complexity while maintaining extended coverage.
3Adaptability or versatility
If the trackable apparatus moves beyond the common coverage area, then the tracking capability is lost, but adding more base stations increases cost
Solution Approach 1:
Each secondary base station is designed to be multi-functional, serving both as a tracking signal source and as a boundary marker for coverage areas. By strategically positioning base stations to create overlapping coverage zones and using the control apparatus to switch between them, the system achieves extended tracking capability without requiring a proportional increase in the number of base stations.
Data Source
AI summary
An environmental control system, control apparatus, and control method thereof are provided. The control apparatus receives a plurality of sets of sensed signals from a trackable apparatus, wherein each set of sensed signals is sensed from one of a primary base station and a first secondary base station and the last set of sensed signals is sensed from the primary base station. The primary base station, the first secondary base station, and a second secondary base station have a common coverage area. The control apparatus determines that the trackable apparatus has moved at least a predetermined distance in the common coverage area in a direction away from the first secondary base station and toward the second secondary base station. In responses to the determination, the control apparatus transmits instruction signals to turn off the first secondary base station and turn on the second secondary base station.
