Abstract
With the maturity of UAV technology, especially the cost of the four rotor unmanned aerial vehicle is decreasing, the unmanned aerial vehicle (UAV) will be a trend in the future. At the same time, because ZigBee has the characteristics of low cost, low speed and short transmission distance, we use ZigBee to achieve the transmission of image files between UAV and ground receiving system computers. This paper introduces the system design and software program module hardware node design, the first use of ZigBee wireless network as a data link, and then collected by the UAV to the ground of the computer image transmission, in the process of transmission by subcontracting, merging, stop and wait Agreement to ensure the correctness of data transmission right. Through experimental test, the correct transmission of image files between UAV and ground end computer can be realized when the image data is less than 1024K bytes.
