Parking Lot Edge Base Units for Automated Valet Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automated valet parking systems rely on central servers for infrastructure assistance data processing, leading to increased data transmission paths, hardware complexity, and costs, as well as the need for extensive cabling and server rooms.
Innovation Solution
Implementing an edge computing architecture with base units connected in series within the parking lot, each unit connected to a subset of environment sensors, reducing data transmission paths and bandwidth requirements, and eliminating the need for central servers and server rooms by using a daisy chain topology.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a central server architecture is used for infrastructure assistance data processing, then data processing capability is improved, but data transmission path length increases and hardware complexity increases
Solution Approach 1:
The patent divides the centralized server architecture into multiple distributed base units (first base unit, second base unit, etc.) that are spatially separated and functionally independent. Each base unit processes sensor data locally for its specific area, eliminating the need for a single complex central server while maintaining overall system processing capability.
Solution Approach 2:
Each base unit is equipped with local processing capabilities to handle sensor data from its immediate environment. The first base unit processes data from sensors in its area, and the second base unit processes data from its area, providing localized processing that reduces transmission distances and hardware requirements.
2Power
If a central server is used for infrastructure assistance data processing, then data processing capability is improved, but data transmission bandwidth requirements increase
Solution Approach 1:
The patent segments the data processing function across multiple base units, each handling only the sensor data from its local area. This segmentation reduces the total bandwidth required compared to a central server that would need to receive and process all sensor data from the entire parking lot.
Solution Approach 2:
Each base unit processes sensor data locally, transmitting only the resulting infrastructure assistance data rather than raw sensor data. This local processing approach significantly reduces the quantity of data that needs to be transmitted across the network.
3Power
If a central server architecture is used, then infrastructure assistance data can be processed, but extensive cabling and server rooms are required
Solution Approach 1:
The patent divides the system into multiple small, distributed base units that can be installed throughout the parking lot without requiring a centralized server room. This segmentation eliminates the need for extensive cabling to a central location and reduces installation complexity.
Solution Approach 2:
Each base unit is self-contained with its own processing capabilities and wireless communication interface, allowing it to operate independently without requiring connection to a central server infrastructure. This self-service approach simplifies installation and eliminates the need for server rooms.
4Length of stationary object
If base units are arranged spaced apart in series, then data transmission path is shortened, but system coverage area is divided
Solution Approach 1:
The patent divides the parking lot coverage area into multiple zones, with each base unit responsible for a specific local area. The first base unit covers its local area, and the second base unit covers another local area, collectively providing full coverage while maintaining short transmission paths within each zone.
Solution Approach 2:
The patent combines the coverage areas of multiple base units to provide comprehensive infrastructure assistance data for the entire parking lot. While each base unit operates independently with short transmission paths, their combined coverage encompasses the whole area.
