摘　　要：针对我国现有青贮圆草捆打捆机控制部分自动化程度较低,存在草捆缠网圈数不稳定、质量偏差大等问题,运用STEP7-Micro/WIN软件编程,设计研发一种以PLC控制器、人机接口触摸屏、模拟量模块为核心,配备相应传感器、执行器硬件的全自动打捆机控制系统。该系统带有可视、简洁的过程监视界面,采取软硬件结合防干扰措施。样机试验结果表明:在该控制系统工作下,草捆圈数合格率100%,草捆密度最大相对误差3.9%,其他各项作业功能均达到设计要求。For the problems of the low degree of automation of existing silage round baler control system,the unstable number of bale net laps and the big deviation of bale weight,a new automatic baler control system was designed by integrating PLC,human-machine interface touch screen and analog module and equipped with appropriate sensors and actuators with STEPT-Micro/WIN software for programming. This system had a visual, simple interface and took certain measures of software and hardware to avoid interference. Through test, the system was verified that baling laps qualification rate was 100%, baling density maximum relative error was 3.9%. The performance of the new design could meet the expected requirements.
