摘要
为满足设施大棚内蔬菜机械化播种的小型化、绿色化、智能化作业需求,结合常见蔬菜的播种农艺特征,通过构建参数化播种控制模型,设计了一套小型蔬菜精量播种机智能控制系统。硬件部分以STM32F103C8T6单片机为主控模块,通过CAN总线实现分布式通信,集速度检测、压力感知、高精度执行模块于一体,确保了系统在复杂工况下运行的稳定性;软件部分基于分层架构,采用C语言开发,结合增量式PID算法与多源信号融合技术,实现了作业参数的可视化设置与实时监测。试验结果表明,该系统支持株距、播种深度、镇压力等参数的协同调控,可满足设施大棚狭小空间下的高精度、低污染作业需求,为绿色智能播种装备的研发提供了技术支持。
To meet the needs of miniaturized,green,and intelligent operations for mechanized seeding of vegetables in facility greenhouses,a set of intelligent control system for small-scale vegetable precision seeders was designed by constructing a parameterized seeding control model,combining with the seeding agronomic characteristics of common vegetables.The hardware uses the STM32F103C8T6 single-chip microcomputer as the main control module,realizes distributed communication through the CAN bus,and integrates speed detection,pressure sensing,and high-precision execution modules to ensure the stability of the system under complex working conditions.Based on a hierarchical architecture,developed in C language,the software was written by integrating the incremental PID algorithm and multi-source signal fusion technology to achieve visual setting and real-time monitoring of operation parameters.The test results show that the system supports the collaborative regulation of parameters such as plant spacing,seeding depth,and compaction pressure,can meet the requirements of high-precision and low-pollution operations in the narrow space of facility greenhouses,and provides technical support for the research and development of green intelligent seeding equipment.
