【Abstract】 The paper designs an automatic control system in rice direct seeding machine. The system employs infrared sensitive tubes to detect seeding signals,hall elements to detect distance signals and achieves the automatic adjustment of seeding amounts with the help of chip micro-computer and stepping motor. In addition,the system realizes even seeding and intelligent control of rice direct seeding machine,which contribute a lot to improving the seeding quality and the crop output.更多还原
