Optimization of Condition Detection and Precision Control for Electric Drive Precision Seeder for Jiangsu Farming

摘要: 本文以江苏高强度耕作、紧凑播种窗口为背景，从粒距、播深、下压力等关键指标入手，提出多传感器协同检测和闭环控制方案。依靠NI-CompactDAQ和LabVIEW，把GNSS、光电、角度、轴销力、微压差、振动和CAN数据融合起来，形成同步采集、在线解算、可视化监测和TDMS/CSV存储的一体化链路，给整机性能评价和优化设计赋予连续的数据支撑。根据静态和田间试验结果，给出耦合补偿、参数整定、工况适配思路，为江苏稻麦轮作区、苏北旱作区高速精播质量提升提出优化路径。

Abstract: This paper, set against the backdrop of high-intensity cultivation and compact sowing windows in Jiangsu, proposes a multi-sensor collaborative detection and closed-loop control solution by focusing on key metrics such as row spacing, sowing depth, and downward pressure. Leveraging NI-Compact DAQ and LabVIEW, it integrates GNSS, photoelectric, angular, pin force, micro-differential pressure, vibration, and CAN data to establish an integrated chain of synchronous acquisition, online calculation, visual monitoring, and TDMS/CSV storage, providing continuous data support for machine performance evaluation and optimization design. Based on static and field test results, it offers insights on coupling compensation, parameter tuning, and operational condition adaptation, proposing optimization pathways to enhance the quality of high-speed precision sowing in Jiangsu’s rice-wheat rotation zones and northern dryland areas.
