Global Grid Map for Multi-Site Roadbed Network Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional roadbed networks operate independently, leading to repeated perception of overlapped areas and incomplete tracking of targets, as each base station cannot inherit perception results from adjacent stations, resulting in unrobust tracking and repeated detection of targets.
Innovation Solution
A method and system for constructing a global grid map that integrates perception results from multiple roadbed base stations, allowing for global tracking of targets by indexing detected target lists and associating overlapping information to create a unified tracking list, ensuring continuous tracking and complementarity of perceived results.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each roadbed base station perceives independently with a complete perception solution, then each base station can autonomously detect targets within its range, but perceived results are independent and overlapped areas are repeatedly perceived without complementarity
Solution Approach 1:
The patent merges perception results from multiple independent roadbed base stations by constructing a global grid map that integrates detection data from different sites. The terminal device combines target information from multiple base stations, assigns unified tracking IDs, and maintains continuous tracking across the network, transforming independent perception into coordinated global perception.
2Measurement precision
If each roadbed base station is equipped with a complete perception solution, then each station can independently detect targets, but this increases system complexity and causes repeated perception in overlapped areas
Solution Approach 1:
The patent segments the perception system into two parts: roadbed base stations perform local detection and transmit results, while a terminal device performs global integration and tracking. This segmentation allows base stations to use simplified perception solutions while maintaining overall system accuracy through centralized data fusion and unified tracking management.
3Ease of operation
If perceived results are independent at each base station, then each station operates autonomously, but targets moving between stations cannot be continuously tracked
Solution Approach 1:
The patent implements feedback mechanisms where base stations transmit detected target information to the terminal device, which maintains a global tracking list and sends back tracking status. This feedback loop enables continuous tracking across stations while preserving autonomous operation, as each base station independently detects but the system collectively maintains robust tracking through information exchange.

AI summary
A method, a device and a system for perceiving a multi-site roadbed network are provided. The method includes: constructing a global grid map of the roadbed network that is marked with a position of the system for perceiving at least two roadbed base stations and a perceived range of the system; receiving the detected target list transmitted by each of the systems for perceiving at least two roadbed base stations, where the detected target list is the set of the preset detected targets; according to the position of each system for perceiving the roadbed base station, indexing into the global grid map the detected target list transmitted by each system for perceiving the roadbed base station to generate a global tracking list; and tracking the preset detected target in the detected target list transmitted by the system for perceiving the roadbed base station according to the global tracking list.
