The invention discloses a high-stability high-precision geographic information surveying and mapping device, which is provided with a main propeller group mechanism and an auxiliary propeller group mechanism at the same time, can realize balance adjustment of an unmanned aerial vehicle according to the actual vibration amplitude condition, and ensures the stability and stability of the unmanned aerial vehicle during surveying and mapping. Meanwhile, the control condition is improved, when the surveying instrument conducts surveying and mapping, and the fluctuation amplitude is lower than or equal to a set threshold value, the controller only controls the rotating speed of each paddle of the auxiliary propeller set mechanism so that the fluctuation amplitude can be reduced, and the rotating speed of each paddle of the main propeller set mechanism can not be changed; and when the fluctuation amplitude is higher than a set threshold value, the controller adjusts the rotating speed of each paddle of the main propeller group mechanism so as to reduce the fluctuation amplitude, so that the control stability can be effectively improved, the stability of the unmanned aerial vehicle during surveying and mapping is ensured, and the vibration and fluctuation of the unmanned aerial vehicle are reduced.

    本发明公开了一种高稳定性的高精度地理信息测绘装置,其在设置主螺旋桨组机构的同时,并设置副螺旋桨组机构,可根据实际振动幅度情况来实现对无人机的平衡调节,保证测绘时无人机的稳定性和平稳性,本发明同时还对控制情况进行改进,在测绘仪进行测绘时,当波动幅度低于或等于设定阈值时,所述控制器仅控制所述副螺旋桨组机构的各个桨叶的转速来使得所述波动幅度降低,并使得所述主螺旋桨组机构的各个桨叶的转速不变;当所述波动幅度高于设定阈值时,所述控制器才调节所述主螺旋桨组机构的各个桨叶的转速以便使得所述波动幅度降低,可有效的提高控制的平稳性,保证无人机在测绘时的平稳能力,减小无人机的振动与波动。
