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.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
