Miniature Wireless Image Transmission System Design

With the continual development of subminiature equipment,minisize wireless image-transmitting system becomes a hotspot in scientific research. It can spy in little area battlefield. It can also use in traffic surveillance,reconnaissance the situation of a disaster,reconnaissance terrain and so on. It has a broad application prospect. First this thesis analyzed different kinds of little area battlefield detective means,it proved it was necessary to design minimize wireless image-transmitting system. Secondly this thesis introduced the current state of application and development of the minimize wireless image-transmitting system,and we designed a new little area battlefield detective system on this base. We carried out battlefield scout and achieved small area battlefield scout aim with low cost ,easy use and getting rid of weather restrict via a pigeon schlep micro electronic device. Based on system guideline, two projects were designed; each project included pigeon-carrier part and ground part. Project one used simulation communication mode, Pigeon-carrier was composed of micro photograph part,video transmitter. It scouted the flight field of the military pigeon and transmitted the video signal to ground part. ground part included secondary planet receiver,USB video-box and computer. It received the video signal from pigeon part and stored,dealt with the video signal. Project two used digital communication mode, pigeon-carrier used CMOS Image sensor as video-in device, used microprocessor as a control unit, used wireless transceiver chip transmitting the image data. Ground part included homogeneous wireless transceiver chip and computer. It received,processed and stored the image data from pigeon part. The two projects had small size,little weight and needed little energy, according with the system technology guideline.
