Abstract:0.13%~2.12%。In order to improve the precision of soil moisture testing under natural causes and nonlinear system, the fuzzy controller and signal pickup assembly based on DSP(TMS320VC5402) were constructed by neural networks technique, and the signal processing and optimized method were raised. The BP learning algorithm for fuzzy control rule and amending rule were determined, moreover, the experiment and verification were done with the system. The results of experiment show the errors of soil moisture test by neural networks technique are 0.13%~2.12% lower than by routine method.

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.
