Description

technical field [0001] The invention belongs to the field of transportation, and more specifically relates to a highway toll recognition device based on an electrochromic device and a manufacturing method thereof. Background technique [0002] The role of license plate recognition in expressway toll collection is to reduce travel time, improve the technical content of the toll management system and assist personnel management to prevent card loss and toll leakage. [0003] However, the surface of the existing toll recognition device is greatly affected by sunlight, etc., which easily reduces the recognition accuracy, thereby causing low efficiency and leakage of fees. Contents of the invention [0004] Aiming at the problems existing in the background technology, the present invention provides a highway toll recognition device based on an electrochromic device and a manufacturing method thereof, which improves the structure and manufacturing process of the self-powered ele...
