基于FPGA的农田图像采集与3G无线传输系统设计
Acquisition System and Wireless Transmission by 3G for Farmland Image Based on FPGA
摘要
Abstract
According to the existing problem of high power consumption, high cost and low speed of wireless transmission for field image acquisition devices, a field image acquisition and transmission system based on FPGA and 3G wireless communication technology was designed. The system consisted of field image acquisition terminal and remote servers, which communicate with each other through the 3G wireless network for image transmission. The implementation of JPEG image compression algorithm based on FPGA was researched. The drive and data communication for 3G module had been achieved. The experiments showed that the system could acquire and transmit the image wirelessly in no time, and it needed about 5. 42 s to transfer an image, frames were never dropped.关键词
