Title:
LIGHT-CONVERGENCE ADAPTATION SYSTEM FOR SHORT-RANGE TUNNEL
Document Type and Number:
WIPO Patent Application WO/2022/048167
Kind Code:
A1
Abstract:
A light-convergence adaptation system for a short-range tunnel, comprising two resistance bars (1) penetrating through a road surface; the two resistance bars (1) are provided on the same straight line and are fixedly connected to each other by means of an insulating layer at positions where the two resistance bars close to each other; each resistance bar (1) is respectively provided with a vision buffer structure; the vision buffer structure comprises first video buffer lamps (21), second video buffer lamps (22) and third video buffer lamps (23); each first video buffer lamp (21) is located on the outer side of said tunnel, and two first photosensitive resistors (31) are in communication with the top of each first video buffer lamp; two second photosensitive resistors (32) are in communication with an end portion of an end of each resistance bar (1) located inside the tunnel; the two first photosensitive resistors (31) are in communication with the two second photosensitive resistors (32) by means of a bridge circuit; and a plurality of search lamps (4) are provided on the inner side of said tunnel.
