Design and Experiment of Intelligent Control System of Corn Seeder

针对传统玉米播种机播种深度不均匀、人工劳动强度大等问题,基于传感器技术、嵌入式系统和自动化控制算法,提出基于电气自动化技术下玉米智能播种机控制系统设计方案,该系统以西门子S7-200 PLC控制器为核心,通过实时监测土壤条件和作物需求,能够自动调整播种机工作参数,确保播种深度均匀且适合不同地块的土壤特性。此外,该系统使操作更加便捷,减少了人工劳动强度。田间试验结果表明,应用该系统后播种深度的均匀性明显提高,作物生长状况更为一致,产量有显著提升。研究结果旨在提高玉米种植的效率和质量,减轻农民的工作压力。

In view of the problems of uneven sowing depth and high manual labor intensity of traditional corn seeders,based on sensor technology,embedded system and automatic control algorithm,a control system design scheme based on electrical automation technology is proposed,the system with Siemens S7-200 PLC controller as the core,through real-time monitoring of soil conditions and crop demand,the planter operating parameters can be automatically adjusted to ensure that the sowing depth is uniform and suitable for the soil characteristics of different plots.In addition,the system makes the operation more convenient and reduces the labor intensity.The results of the field test showed that the uni-formity of the sowing depth was significantly improved,the crop growth was more consistent,and the yield was signifi-cantly improved.The results of the study aim to improve the efficiency and quality of corn planting and reduce the work pressure of farmers.
