Design And Realization Of A Simulating Remote Photography Device

Remote photographing is increasingly used for observing the earth. Designing and realizing a simulating remote photography device has important significance for improving high technology lecture's quality and staff room's scientific research task's development.The device uses a pushing-broom visible light linear array CCD camera with camera lens for photographing the lab scene. Data can be received wirelessly and image can be displayed by PC. The paper schemes out machanical pushing-broom system and brings forward camera lens'improving scheme. The work can make camera scan special location in the lab. In circuit design system modularization designing idea is adopted; the schemes of transmitting system and receiving system take the Data Signal Prosess chip TMS320VC5402 and A7121 module as the core chip; by the USB chip PDIUSBD12 the collecting circuit can communicate with computer. This paper presents corresponding hardware scheme and software flow chart. The hardware and the software have been debugged. The debugging result indicates this system can meet the demand that the image data is collected and displayed in real time.Firstly, whole thoughts of designing the system are narrated in the paper. Then, those technical details in each module design are explained in the middle three chapters. Finally, system's schematic sheet and PCB drawing is presented in the paper and some problem in designing the system and some measurds for solving those problems are mentioned; also, a logical thought for improving the system is brought forward. This paper can offer some valuable reference for researching image collecting and processing system or wireless data transmitting system.
