A multi-rotor unmanned aerial vehicle performance testing platform and method

Abstract

The invention discloses a performance test platform and method for a multi-rotor unmanned aerial vehicle. The test platform comprises a base, a stand column, a top frame, a performance test instrument and a calculation processing center; the bottom of the stand column is connected to the base through a ball-head universal bearing, and the top of the stand column is connected to the top frame through a ball-head universal bearing; the top frame is hung on an external rigid body through an elastic inhaul cable; a rack of the multi-rotor unmanned aerial vehicle is provided with a sleeving ring arranged on the stand column in a sleeving mode; the performance test instrument comprises an on-vehicle test instrument body which is arranged on the multi-rotor unmanned aerial vehicle and used for testing flight attitude information and work condition information of the multi-rotor unmanned aerial vehicle and a ground test instrument body which is arranged on the test platform and used for testing external response information of the multi-rotor unmanned aerial vehicle; the calculation processing center comprises a data collecting unit and a data analyzing unit. The test platform is simple in structure, good in flexibility and capable of accurately testing multiple performance indexes of the aerial vehicle.

Description

technical field [0001] The invention relates to a testing device and method, in particular to a multi-rotor unmanned aerial vehicle performance testing platform and method. Background technique [0002] In recent years, multi-rotor unmanned aerial vehicles have been widely used in various fields such as military, scientific research, and civilian use due to their advantages of safety, small size, flexible application, and high operating efficiency. Unmanned aerial vehicles have a broad market in both civilian and military fields. And application prospects, especially in extremely dangerous and harsh environments, it has shown its application value. [0003] After the emergence of multi-rotor unmanned aerial vehicles, its average life expectancy is not high. With the expansion of the functions of the multi-rotor UAV system, the airborne equipment is becoming more and more advanced, complex and expensive. Due to the advanced system performance and high cost, the service time ...

AI Technical Summary

Problems solved by technology

[0004] At present, the test technology adopted by the UAV performance test platform is not mature enough, and it is rare in practical applications, and there are still two major problems in the existing UAV performance test platform: one is the existing The functions of the unmanned aerial vehicle performance test platform are not comprehensive enough, and none of the existing unmanned aerial vehicle performance test platforms is suitable for testing the comprehensive performance of unmanned aerial vehicles, but only for a certain performance of unmanned aerial vehicles It is developed by the test, which leads to the user's reference index is not comprehensive enough, it is difficult to choose; second, the reference parameters given by the existing unmanned aerial vehicle performance test platform are not accurate enough, and the existing unmanned aerial vehicle performance test platform is tested. The parameters are all performance parameters obtained when the UAV works in an ideal environment, but in actual operations, the environment is highly variable, and factors such as load, wind force, vibration, etc. will have a great impact on the performance of the UAV. Will lead to bias in the user's choice of UAV
