Abstract
The light signal of navigation aids plays an important reference role for ship pilots, especially in the long channel manually dredged (Dagusha Channel of Tianjin Port). The stable performance of beacon lights is of great significance for ship pilots to identify the channel, determine the ship's position and avoid dangerous objects, which is directly related to the navigation safety of ships. Based on the observation of the backlight of Dagusha Channel in Tianjin Port and the analysis of the location of the navigation aids in the area under its jurisdiction, this paper introduces the optical performance of TYH-120 integrated beacon light in the channel, and puts forward a further optimization plan.
