Embodiment Construction

[0030] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0031] With the continuous development and maturity of microelectronics technology and computer integrated chip manufacturing technology, DSP processors are not only widely used in communication and video signal processing due to their fast computing capabilities, but also gradually used in various advanced control systems. AD's ADSP-21xx series provides low-cost, low-power consumption, high-performance processing capabilities and solutions. The ADSP-2188 instruction execution speed is as high as 75MIPS, plus an independent arithmetic logic unit, with powerful digital signal processing ability. In addition, large-capacity RAM is integrated into t...

Abstract

The invention relates to an automatic control system of a three-wing two-paddle recombination type unmanned aerial vehicle (UAV). In order to improve the operational speed and ensure the stability and the reliability of the control system of a UAV, a field programmable gate array (FPGA) processor is introduced into a one-chip data signal processor (DSP) to form a DAP+FPGA dual-core processor, the structure adopting a single paddle of the conventional UAV is abandoned, and a structure with a single wing and positive and negative paddles is introduced into the system, so that the power performance of the system is greatly improved; in order to prolong the aerial photo time of the UAV, the system adopts a high-performance lithium ion battery to realize a function of synchronously controlling a six-axis motor by a single controller; and a multi-axis servo system with the maximum workload in the control system of the UAV and data signal processing are processed by an FPGA to give full play to the characteristic of high data processing speed of the FPGA, so that the division of work of the DSP and the FPGA processor is realized, and the DSP is freed from the heavy workload.

Description

technical field [0001] The present invention relates to the technical field of unmanned aerial vehicle (UAV) (Unmanned Aerial Vehicle), and in particular relates to the automatic control system of the three-wing and double-propeller recombined unmanned aerial vehicle UAV. Background technique [0002] Aerial photography and surveying and mapping are the strengths of manned helicopters. However, low-altitude, small-scale, high-precision aerial photography and surveying and mapping are often encountered in urban planning, development, real estate, and enterprise factory buildings. Compared with manned helicopters, UAVs perform such The task has the characteristics of high efficiency and low cost. UAV remote sensing is the use of advanced unmanned aerial vehicle technology, remote sensing sensor technology, telemetering and remote control technology, communication technology, GPS differential positioning technology and remote sensing application technology to quickly acquire la...
