Problems solved by technology

Because these traditional inspections keep the measured object on the ground, without various interferences and responses of actual flight conditions, the inspection is difficult to be sufficient, so it is difficult to check many faults in the design of the UAV system or verify the actual situation of state transitions. Flight simulation is more accurate.

The flight route data is loaded in the control and measurement system 5 and converted into component control instructions for driving the multi-latitude motion platform system 2, and the continuous combined driving simulates the route flight of the UAV. , realize the flight simulation test or research environment; in the test, record the movement of the multi-latitude motion platform system 2 and the movement of the UAV at the same time, and compare the differences; analyze the working status of each system of the UAV, and analyze the correlation or problems of the data. The flight route data can be selected as typical data of actual flight for verification analysis, or can be typical theoretical route data for research to avoid risky actual flight.

Embodiment 3

[0027] Example 3. The unmanned aerial vehicle accepts the flight verification and research of guidance control. The simulation test system of this example is the same as that of Example 1, the control mode is changed, similar to the reverse control, and the pre-programmed control of the control and measurement system 5 in Example 1 is changed to tracking movement by the target photodetector on the UAV target, and provide control instructions to the control and measurement system 5 according to the control law to drive the multi-latitude motion platform system 2 motion simulation to guide the flight of the UAV; among them, according to the needs of tracking flight control, supplementary control information can be added, such as communication data link, guidance The radar information source; the control source is different, and the purpose of the simulation test system is also different. It is the same as verifying the ability of the UAV to track moving targets, such as aerial r...

Abstract

The invention discloses a simulation test method and a simulation test system for an unmanned aerial vehicle (UAV) system. The method comprises the following steps of: arranging the UAV system on a multi-latitude motion platform system, and providing the multidimensional motion of the UAV system by using the multi-latitude motion platform system; providing signal data of simulated motion for the UAV system by using a signal source simulation system; providing a control logic process of motion simulation, platform motion amount closed loop measurement and the corresponding measurement of the UAV system by using a control and measurement system; and providing a drive source required by the motion of the multi-latitude motion platform system by using a motion servo system, and providing a parameter record, real-time display and superposed background information by using a simulation parameter recording and displaying system. By the method and the system, the UAV system can be subjected to dynamic test check and simulation on the ground, and actual flight is replaced, so that actual flight risk is obviously reduced, a test verification period is shortened, and cost is saved.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle system simulation test method and a simulation test system. Background technique [0002] As a model equipment or a general product, the test before the first flight of the UAV is necessary for the safe first flight. At present, the methods for realizing UAV performance testing mainly adopt ground loading inspection and flight test. The ground loading inspection includes power-on inspection, inspection under power running and coasting inspection. Because these traditional inspections keep the measured object on the ground, without various interferences and responses of actual flight conditions, the inspection is difficult to be sufficient, so it is difficult to check many faults in the design of the UAV system or verify the actual situation of state transitions. Flight simulation is more accurate. However, there are risks in actual flight. How to conduct more sufficient test inspections on the groun...
