Parking Lot Vehicle Sensor Activation for Abnormality Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security systems for vehicles fail to effectively monitor abnormal situations such as fires, incidents, or accidents in parking lots or their surrounding regions, necessitating improved security through enhanced monitoring capabilities.
Innovation Solution
A system utilizing infrastructure sensors and vehicle-mounted exterior monitoring sensors to detect and respond to abnormal situations by activating vehicle exterior monitoring sensors to capture occurrence locations, specifying vehicles with these sensors, and acquiring detection data for continuous monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If infrastructure sensors and vehicle-mounted sensors are used to monitor abnormal situations in parking lots, then detection accuracy and security monitoring capability are improved, but device complexity and system cost increase
Solution Approach 1:
The monitoring system is divided into two segments: infrastructure sensors fixed in the parking lot and vehicle-mounted exterior monitoring sensors. This segmentation allows the system to leverage existing vehicle sensors without requiring a complete centralized monitoring system, thereby improving detection accuracy while controlling complexity.
Solution Approach 2:
The vehicle exterior monitoring sensors serve dual purposes: they monitor abnormal situations in the parking lot and simultaneously protect the vehicle itself. This multi-functionality reduces the need for dedicated security sensors, improving detection capability without proportionally increasing system complexity.
2Reliability
If vehicle exterior monitoring sensors are activated to capture occurrence locations of abnormal situations, then security monitoring capability is improved, but energy consumption and loss of time for sensor activation increase
Solution Approach 1:
The system pre-identifies vehicles parked in the monitoring region and pre-positions their exterior monitoring sensors in standby mode. When an abnormal situation is detected by infrastructure sensors, the system immediately activates the relevant vehicle sensors, reducing activation time and energy consumption compared to full-system activation.
Solution Approach 2:
Instead of continuous activation, vehicle exterior monitoring sensors are activated periodically or event-driven based on detections from infrastructure sensors. This periodic activation maintains security reliability while significantly reducing energy consumption compared to continuous operation.
3Reliability
If multiple vehicle exterior monitoring sensors are deployed to monitor the same region, then detection coverage and reliability are improved, but device complexity and coordination difficulty increase
Solution Approach 1:
The system implements feedback mechanisms where infrastructure sensors continuously monitor the parking lot and provide real-time information to the command transmission unit. When abnormalities are detected, the system coordinates only the necessary vehicle sensors based on the specific incident location and type, reducing coordination complexity while maintaining reliability through targeted feedback-driven activation.

AI summary
A device that monitors an abnormal situation that has occurred in a region inside or around a parking lot using a vehicle in the region includes: an information acquisition unit that acquires state information representing a state within the region; an abnormality detection unit that detects the abnormal situation and specifies an occurrence location of the detected abnormal situation based on the state information; and a command transmission unit that transmits a command for activating a vehicle exterior monitoring sensor provided in the vehicle parked around the occurrence location specified by the abnormality detection unit and causing the vehicle exterior monitoring sensor to detect the occurrence location to the parked vehicle.
