METHODS AND SYSTEMS FOR SENSING A ROAD SURFACE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240053266 titled 'METHODS AND SYSTEMS FOR SENSING A ROAD SURFACE
Simplified Explanation
The abstract describes a system for remote sensing of a road surface using radiofrequency identification (RFID) technology. The system includes an antenna that attaches to the front end of a vehicle and is used to transmit and receive RF signals. At least one RFID tag is also attached to the front end of the vehicle. An RFID reader is configured to transmit a RF signal towards the road surface, and the RFID tag receives a backscattered RF signal from the road surface. The RFID reader then analyzes the phase and magnitude information of the received signal to determine the condition of the road surface.
- The system uses an antenna attached to a vehicle to transmit and receive RF signals.
- RFID tags are attached to the front end of the vehicle.
- An RFID reader is used to transmit RF signals towards the road surface and receive backscattered RF signals from the RFID tags.
- The phase and magnitude information of the received signal is analyzed to determine the condition of the road surface.
Potential Applications:
- Road condition monitoring: The system can be used to remotely monitor the condition of the road surface, such as detecting potholes, cracks, or other damages.
- Maintenance planning: By analyzing the data collected from the RFID tags, road maintenance activities can be planned more efficiently and effectively.
- Traffic management: The system can provide real-time information about the road conditions, allowing for better traffic management and routing decisions.
Problems Solved:
- Manual road inspections can be time-consuming and costly. This system provides a remote sensing solution that eliminates the need for physical inspections.
- Traditional methods of road condition monitoring may not provide real-time data. The RFID-based system allows for continuous monitoring and immediate detection of road surface conditions.
Benefits:
- Cost-effective: The system eliminates the need for manual inspections, reducing labor and equipment costs.
- Real-time monitoring: The system provides real-time data on road conditions, allowing for timely maintenance and improved safety.
- Non-intrusive: The system can be easily attached to existing vehicles without the need for major modifications or disruptions to traffic flow.
Original Abstract Submitted
an example system for remote sensing of a road surface includes an antenna configured to transmit and receive radiofrequency (rf) signals, where the antenna is configured to attach to a front end of a vehicle; at least one radiofrequency identification (rfid) tag, where the at least one rfid tag is configured to attach to the front end of a vehicle; and an rfid reader, wherein the rfid reader is configured to: cause the antenna to transmit a radiofrequency signal toward a road surface, where the at least one rfid tag receives a backscattered rf signal from the road surface; receive, from the antenna, an rfid signal from the first rfid tag, the rfid signal comprising phase and magnitude information; and analyze the phase and magnitude information to determine a condition of the road surface.
