    摘要:

    針對目前農(nóng)田圖像采集裝置功耗大、成本高、圖像無線傳輸速度慢的問題，設(shè)計了一套基于FPGA和3G無線通信技術(shù)的農(nóng)田圖像采集傳輸系統(tǒng)。該系統(tǒng)由農(nóng)田圖像采集終端和遠(yuǎn)程服務(wù)器組成，服務(wù)器與終端通過3G無線網(wǎng)絡(luò)進(jìn)行圖像傳輸。研究了基于FPGA的JPEG壓縮算法，實現(xiàn)了3G模塊的驅(qū)動與遠(yuǎn)程數(shù)據(jù)通信。試驗表明，系統(tǒng)能夠快速采集圖像并進(jìn)行無線傳輸，傳輸一幅圖像所需的時間約為5.42s，無丟幀現(xiàn)象。

    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.
