Parking Space Detector Installation and Sensing Principle
1. Geomagnetic Sensing Layer
Detects changes in the Earth's magnetic field, generating a magnetic disturbance signal when a metal vehicle enters.
2. Microwave Radar Layer
Emits microwave signals and receives reflected waves to accurately determine vehicle presence and movement status.
3. AI Fusion Algorithm
Triple signals are fused and analyzed by an AI algorithm to output the final parking space status.
Judgment Result
Surface installation is suitable for rapid deployment in existing parking lots, with single-point installation taking only 5 minutes; embedded installation is suitable for new parking lots, with a concealed appearance and stronger pressure resistance, capable of withstanding vehicle碾壓 weighing over 40 tons.
Smart Parking Lot Application Scenarios
Real-time Monitoring and Guidance
The system instantly transmits the occupancy status of each parking space to the management platform, helping drivers quickly find available parking spaces through parking guidance signs and mobile applications, reducing cruising time by 40%, and effectively improving parking lot efficiency and user satisfaction.
The system can integrate existing parking payment systems and surveillance cameras, providing a complete parking lot management solution. Historical data analysis helps managers understand key indicators such as peak/off-peak hours and average parking duration, serving as a basis for adjusting operational strategies.
