Parking Space Monitoring via Sensor Consensus Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current parking space monitoring systems using environment sensors often result in high false-negative and false-positive object detections, which affect the reliability and availability of determining whether a route is free for motor vehicles.
Innovation Solution
A method and device utilizing multiple stationary environment sensor devices to monitor a common parking space area, where the area is considered free for motor vehicles only if all sensors agree, and not free if all sensors indicate otherwise, with a processor determining the navigability based on sensor data and implementing a repetitive verification process to detect potential errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple environmental sensor devices are used to monitor the parking area, then the reliability of detection is improved, but the device complexity increases
Solution Approach 1:
The monitoring system is segmented into multiple independent environmental sensor devices, each monitoring the same parking area from different positions. This segmentation allows the system to achieve higher reliability through redundancy while keeping each individual sensor device relatively simple in structure.
2Reliability
If all sensor results must agree to determine the area is not freely passable, then false-negative detections are reduced, but the response time increases
Solution Approach 1:
The system performs a complete evaluation of all sensor results only when necessary to determine that the area is not freely passable. When at least one sensor indicates the area is freely passable, the system accepts this result without requiring full consensus from all sensors, thus reducing unnecessary processing time while maintaining reliability.
3Area of stationary object
If multiple sensor devices are deployed, then the coverage of monitoring area is improved, but the cost of the system increases
Solution Approach 1:
Multiple environmental sensor devices are merged to monitor the same parking area simultaneously. By combining the capabilities of multiple sensors rather than deploying them to monitor different areas, the system achieves comprehensive coverage of the critical monitoring zone while optimizing resource utilization and reducing overall system cost.

AI summary
The invention relates to a concept for monitoring a parking space using a plurality of environment sensor devices, wherein said plurality of environment sensor devices are arranged within the parking space in a stationary manner and are monitoring a common area of the parking space. Only if all the environment sensor devices detect that the area cannot be freely traveled by a motor vehicle, is it determined as the overall result that the area cannot be freely traveled by a motor vehicle.
