烟草移栽机人机接口的设计

摘要

Later stages of tobacco growth are mainly based on tobacco seedling planting distance and gradient.So a man-machine interface was needed to monitor the tobacco seedling planting distance and gradient,a man-machine interface and interactive interface were designed using AT89C52 singleship.In order to reduce the complexity of system,man-machine interface was modular designed,keyboard,LCD and peripheral interface were solidified into the module.Because it undertook 3special interface chips,so it could reduce the cost and optimize the hardware structure.%烟苗的株距和倾斜度直接影响烟草移栽的后期生长,所以就需要能够通过人机接口清楚地监控烟苗的株距和倾斜度,利用AT89C52单片机设计了一个人机接口和交互的界面.为了减小系统的复杂性,对人机接口进行了模块化的设计,将键盘、LCD、外围接口全部固化到模块中,由于它承担了3个专用接口芯片的工作,因此可以降低成本,优化硬件结构.
