Research On Aviation Camera Control System Based On Embedded System1

Aerial camera is a kind of optical instrument for getting remote sensing information in the aircraft. It plays a key role in modern exploration and military reconnaissance. Because aviation camera can be controlled to get the high quality of image information. So it is important to research and design the acquisition control system of aerial camera state.Through the research on the operating principle of aviation camera control system, the paper provides a design of aviation camera control system based on embedded system. It gives a detailed introduction for the hardware circuit design and software programming for each module of the aerial camera control system.The paper presents the aerial camera control system that makes the ARINC429bus module to send control command and acquisition of the flight attitude information to aviation camera. The system controls the camera to work according to the designated work mode and monitors the camera working state. The camera working status data is processed by DSP. And it is displayed by liquid crystal in order to facilitate the operation personnel monitoring. The system not only accomplishes the state parameter high precision measurement, but also realizes the intelligent and automation for the whole control process. After the analysis of system for on-line debugging and experiment of test flight aerial photograph, the system can meet the requirement of the use of aerial camera.
