Rotary tillage depth control system based on Beidou satellite navigation

The invention discloses a rotary tillage depth control system based on Beidou satellite navigation. The system comprises a Beidou satellite navigation system and a controller, wherein two Beidou navigation antennae are installed on the left side and the right side of the central line of a rotary tillage machine, the rotary tillage depth is input into the Beidou satellite navigation system, the controller adjusts the oblique angle position of a rotary tillage device of the rotary tillage machine according to the variable quantity of the altitude positions of the two Beidou navigation antennae,so that the rotary tillage depth of an operation area is equal to the altitude, and the tillage flatness is ensured. 本发明公开了一种基于北斗卫星导航的旋耕深度控制系统，包括北斗卫星导航系统和控制器，在旋耕机中心线左右两侧安装有两个北斗导航天线，将旋耕深度输入北斗卫星导航系统中，控制器根据两个北斗导航天线海拔高度位置变化量，调整旋耕机的旋耕装置倾斜角度位置，使作业区域旋耕深度海拔高度一致，保证耕田平整度。
