Design of active light source system for visual positioning

Abstract

In the calibration system of a particle detector, it is necessary to visually locate an active light source moving in a dark environment. The active light source has a built-in lithium-ion battery, which is wirelessly charged before working, and can work continuously for 24 hours after being charging. According to this need, this paper designs and implements the wireless charging light source system. The system consists of a wireless charging control unit and a wireless light source unit. The wireless charging control unit receives instructions from the host computer to complete the charging of the wireless light source unit, and the wireless light source unit controls the on and off of the LED drive current after receiving the instructions from the control unit. After testing, the active light source can work continuously for 24 hours under the condition of being fully charged, meeting the need of visual positioning.
