摘　　要：随着水稻种植规模的扩大,水稻收割机在农业生产中的应用逐渐广泛,但传统水稻收割机故障率高、智能化程度低,存在割茬高度不均、割茬机构调整不便等诸多问题,导致水稻收割效率低、产能不足。为此,将PLC技术应用在传统水稻收割机上,通过研究分析水稻收割机的结构原理,完成了水稻收割机控制系统的优化设计,并针对控制系统的硬件进行了模块设计,同时完成了控制系统的I/O地址分配,对控制系统的软件流程进行优化。进行了割茬高度试验,结果表明:优化后的水稻收割机控制系统工作稳定性强,作业效率高,能够快速有效地调整割茬机构,实现对割茬高度的精确控制,从而大大提高了劳动生产效率、降低了农民的劳动生产强度。With the expansion of the rice planting scale,rice harvesters have been widely used in agricultural production,but traditional rice harvesters have high failure rates,low intelligence,low stubble height unevenness,and inconvenient adjustment of the stubble mechanism.Problems,resulting in low rice harvesting efficiency and insufficient production capacity.In order to meet the needs of agricultural production,this paper applies PLC technology to the traditional rice harvester.Through research and analysis of the structure principle of the rice harvester,the optimization design of the rice harvester control system is completed.The hardware design of the control system is modularized and completed simultaneously.The I/O address allocation of the control system was optimized,and the software process of the control system was optimized.Finally,the stubble height experiment was performed.The results show that the optimized rice harvester control system has strong working stability,high operating efficiency,and can be fast and effective.Adjust the stubble mechanism on the ground,so as to achieve accurate control of the stubble height,thereby greatly improving labor production efficiency and reducing the labor production intensity of farmers.
