Interface Design of the Infrared Image Acquisition via USB2.0 for High Altitude Reconnaissance Aircrafts

摘要

This paper addresses the use of USB 2.0 to design the interface between the upper computer and the lower infrared image scanner for high altitude reconnaissance aircrafts. An infrared image acquisition interface is developed with respect to USB (Universal Serial Bus) 2.0 standard. This work mainly includes the hardware design, the human machine interface (HMI) coding and the ways to improve the transfer speed. The developed interface has worked well since and the average transfer speed has reached 128Mb/s.Undoubtedly it can meet the requirements for real-time transfer of the images obtained by the infrared line scanner.
