Holder device for installing microwave radar and control system thereof

Abstract

The invention provides a cradle head device for carrying a microwave radar on an unmanned aerial vehicle and a control system of the cradle head device. The cradle head device comprises a cradle head box, a cradle head cover, an upper arm, a lower arm, an upper arm cover plate, a first three-phase direct-current brushless motor and a second three-phase direct-current brushless motor. One end of the lower arm is connected with the holder box through a three-phase direct-current brushless motor I, and the other end of the lower arm is connected with the upper arm through a three-phase direct-current brushless motor II; the first three-phase direct-current brushless motor is fixedly connected with the lower arm, and a rotating shaft of the first three-phase direct-current brushless motor is connected with the holder box. A second three-phase direct-current brushless motor is fixedly connected with the upper arm, and a rotating shaft of the second three-phase direct-current brushless motor is connected with the lower arm. The top end of the upper arm is connected with the unmanned aerial vehicle chassis. The device is provided with a horizontal and pitching adjustment supporting device and system, and is controlled, coordinated and matched by a structure, a hardware circuit and a software program, so that the functions of radar incident angle keeping and data transmission of the flight attitude of the unmanned aerial vehicle are realized.

Description

technical field [0001] The invention belongs to the technical field of automatic control, relates to an unmanned aerial vehicle platform, in particular to a platform device for installing a microwave radar and a control system thereof. Background technique [0002] Microwave radar has the advantages of high resolution, strong penetrating power and low power consumption penetrability. It can realize the acquisition of soil, especially covered soil related information, and realize the all-weather and all-weather monitoring of soil information. With the advantages of convenient transportation, high flexibility, short operation cycle, and high data resolution, UAV microwave remote sensing effectively overcomes the shortcomings of satellite remote sensing technology, such as being greatly affected by weather, low temporal and spatial resolution, and limited by transit cycles. A new method for quickly and accurately sensing soil information on a large-scale farmland scale. Howeve...
