基于多信道路由控制的精量播种机优化设计

Optimization Design of Precision Seeder Based on Multi- channel Routing Control

为了提高花生播种机播种的质量及作业效率,在花生引播机的路径和排种器的控制系统中,引入了多信道独立通信原理,降低了播种过程的漏种率;利用模糊神经网络控制原理,结合模糊域对花生播种机的结构进行了非线性优化设计。为了验证设计的花生精量播种机结构和控制系统的可靠性,对花生播种机进行了田间试验,结果表明:多信道路由花生播种机的合格率要明显高于传统的播种机,重播率要明显低于传统的播种机,破碎率和空穴率都比较低。这说明播种机的路径选择和排种器的控制都达到了最优,为花生播种机的研究和设计提供了理论依据。

In order to improve the quality of sowing peanut seeder seeding,improve working efficiency,control system in peanut sowing machine guide path and metering device,the introduction of multi channel independent communication principle,reducing the leakage rate of seeding process; fuzzy neural network control theory,combining the fuzzy domain structure of peanut seeder the nonlinear optimization design. In order to verify the reliability of the design of peanut sowing machine structure and control system,the field test of peanut planter,find the qualified rate was higher than that of the traditional seeding machine multi channel routing peanut seeder by experiment,the replay rate was significantly lower than that of the traditional sowing machine,the broken rate and hole rate is relatively low,the description of choice and path control metering seeder has reached the optimal,and it provides a theoretical basis for the research and design of the peanut planter.
