Abstract: A motor-operated penetrometer with novel structure and constant-velocity (30mm/s) was developed. The major innovation was to employ ball screw as transmission component of penetration force so that the higher control accuracy and operating efficiency could be simultaneously obtained. Moreover, a microcomputer-based controller associated with GPS and PDA was designed to coordinate the soil penetration resistance and the depth measurements at real-time and to monitor the operating status of the penetrometer. By using of the available hardware and software provided by PDA, the data capacity and the processing ability of field information was significantly improved.

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.
