中文摘要:针对气力式免耕播种机常会发生排种管堵塞、机械传动系统故障以及由于种箱排空而造成的漏播等现象,基于单片机技术设计了一种气力式免耕播种机工作情况监测系统。设计了气力式播种机作业参数监测系统的整体结构与系统电路,完成相关参数的设置。利用监测系统对气力式播种机风机转速、行走速度、播种面积以及种箱料位进行实时监测。试验结果表明,气力式免耕播种机监测系统测量精度高,能够完成工作过程的实时监测。

Abstract:Aim at avoiding seed missing and enhancing working quality of sower, based on the PIC single-chip microcomputer control technology, a monitoring system was designed and applied to monitor the pneumatic no-tillage sower’s performance. The general structure and system circuit of the pneumatic sower monitoring system were designed, and the correlation parameters were set. The fan rotational speed, walking speed, planting area, and material level of pneumatic seeder were monitored real-timely by using the monitoring system. The experimental results showed that the pneumatic sower monitoring system had high precision measurement accuracy. It could complete real-time monitoring of working process.

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.
