基于单片机的精准空投控制系统研究

Research on Precision Air Drop Control System Based on Single Chip Microcomputer

降落伞在降落的过程中,由于多种不确定因素常会偏离预定飞行轨迹,不能按时到达预定目的地或偏离目的地。因而,需要一种有效的精准空投的定位方法,以及设计相关的空投定位装置。通过在降落伞的侧翼装上360°可旋转的螺旋桨以及GPS定位器,采用单片机对GPS返回的坐标值和速度等相关数据进行处理,从而控制电扇的旋转角度与速度。当降落伞做平抛运动时,根据与目标位置的距离,及时调整转角,从而实现降落伞的精准空投。

In the process of landing,the parachute often deviates from the scheduled flight path because of a variety of uncertain factors,and can not reach the intended destination on time or far away from the destination.Therefore,we need an effective precise positioning method for airdrop and design related airdrop positioning device.In this paper,a 360 degree rotatable propeller and a GPS locator are installed on the flanks of the parachute,and the relative data of the coordinates and speed returned by GPS are processed by single chip microcomputer to control the rotation angle and speed of the electric fan.When the parachute is thrown flat,the angle is adjusted in time according to the distance from the target position,so as to achieve precise air drop of parachute.
