This abstract first appeared for US patent application 18033017 titled 'DISTANCE CORRECTION DEVICE, PROCESSING DEVICE, SENSOR DEVICE, DISTANCE CORRECTION METHOD, AND RECORDING MEDIUM
Simplified Explanation
- This patent application describes a device that improves the accuracy of identifying the position of vibrations on a road caused by a vehicle. - The device uses an optical cable installed along the road to detect vibrations and collects vibration data for each optical fiber distance. - It calculates a first vibration value indicating the magnitude of vibration within a specific frequency range for each optical fiber distance. - From the first vibration value, it determines the bridge optical fiber distance, which is the distance to a specific position of the optical fiber installed at a bridge. - The device then corrects the optical distance within a specific range to be closer to the road distance by using the bridge optical fiber distance and the distance from a reference point to the bridge optical fiber position. - The purpose of this invention is to improve the accuracy of identifying the position of vibrations on a road, particularly near bridges, by correcting the optical distance measurements.
Original Abstract Submitted
In order to facilitate accuracy improvement in identification of a position of vibration on a road caused by a vehicle and detected through an optical cable, this distance correction device: derives, from vibration data for each optical fiber distance detected through an optical fiber installed along the road on which the vehicle travels, a first vibration value indicating the magnitude of vibration within a prescribed frequency range for the optical fiber distance; derives, from the first vibration value, a bridge optical fiber distance which is an optical fiber distance to a prescribed position of the optical fiber installed at a bridge; and corrects, from the bridge optical fiber distance and a road distance which is a distance, along the road, from a reference point to a bridge optical fiber position, the optical distance within a prescribed range so as to be closer to the road distance.
