Abstract:Measuring the ground speed is important for a variable rate fertilizer machine.
Since the working environment is hard, the reliability and anti jamming capa
bility of the ground speed collecting system is poor. A ground speed collecting
system for a variable rate fertilizer machine is developed based on Bluetooth. A
n ARM microprocessor is used to receive input signals from the ground speed sens
or, a photoelectric encoder set on one of the wheels of the machine. and calcula
te the working speed. And then the working speed signals are transformed into th
e Bluetooth signal format, and transmitted to variable rate fertilizer controlle
r by the KC111 adapters. The maximum error of the test is 292%. It shows that
the developed system is practical. |
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.
