The Design of Coupler Integrating Infrared Detection and Power Transmission for Wireless Charging of Inspection Robot

Abstract

Wireless power transmission system has been applied in the field of smart grid inspection because of its advantages of non-contact and non-wear. This paper designs a coupler integrating infrared detection and power transmission for the wireless charging of industrial inspection robots. The system scheme integrating infrared detection and power transmission is proposed. The system using 4 infrared sensors to detect the position of inspection robot is established. A prototype of wireless charging system for inspection robot is developed. The 474.18W load power and 91.78% efficiency are realized. When the vehicular coil is offset by 15%, the system still works stably. This paper also compares with other coupler schemes. In addition, The electromagnetic field around the coupler is measured. The measurement results are below the limits.
