Abstract

The present invention provides a pre-detection method for the smooth take-off of a small unmanned helicopter. The method drives the aircraft through the PPM sent by the FPGA controller, uses the sensor to perform the inclination angle of the propeller surface, the distance of the propeller tip, and the fluctuation value of the attitude error to obtain data feedback. Come back to control the output value of PPM, and use data processing software to analyze the stored data. The technical effect of the present invention is: it can realize rapid detection of aircraft, and avoid malfunction due to human factors, greatly improves the pre-flight detection, and further improves the reliability of the whole pre-flight, and is safe. The invention can realize the pretreatment function before take-off of the unmanned helicopter, avoid malfunction due to improper operation, greatly improve the efficiency of take-off, reduce the wrong operation caused by human factors, and reduce the labor force at the same time.

Description

technical field [0001] The invention relates to a control and detection method, in particular to a pre-detection method for controlling a small unmanned helicopter to take off smoothly. Background technique [0002] The small unmanned helicopter has the characteristics of vertical take-off and landing, fixed-point hovering, and low requirements for take-off and landing sites. It can carry various sensors to perform surveillance, intelligence collection, and land survey. It has a wide range of military and civilian applications. and research. However, the take-off and landing process is a multi-engine stage of aircraft flight, especially when the helicopter takes off, it generally requires skilled operators to detect and verify it, and there are many unsafe factors in relying on manual detection of unmanned helicopters. Therefore, the automatic detection before the aircraft takes off is very important. Contents of the invention [0003] The object of the present invention...
