Problems solved by technology

[0003] Existing overload trigger devices are generally fixed installation positions, and will not be calibrated and adjusted according to different models and installation errors
In addition, the helicopter may experience a large acceleration value but a short duration, or a small acceleration value but a long duration, but the speed change of the helicopter is relatively fixed.

Abstract

The invention provides a helicopter overload starting device and an automatic judgment method, which belong to the technical field of avionics. The helicopter overload starting device specifically comprises a triaxial overload sensor, a control module and an overload triggering module, wherein the triaxial overload sensor senses the axial transient acceleration of the helicopter, and the control module identifies the initial acceleration state of the helicopter, is used for receiving the axial transient acceleration and calculating the axial acceleration variable of the helicopter, and controls the opening and closing of the overload trigger module according to the value of the axial acceleration variable. According to the processing scheme, whether the helicopter is overloaded or not is judged by sensing the acceleration variation of the helicopter, the method can adapt to more overload working conditions, and the applicability is high.

Description

technical field [0001] The present application relates to the field of avionics technology, in particular to a helicopter overload starting device and an automatic discrimination method. Background technique [0002] In order to ensure that in the event of a helicopter overload accident, some specific and critical tasks can be completed within a short period of time when the overload occurs (such as starting, throwing and separating, emergency positioning, etc.), it is necessary to monitor the helicopter overload in real time, so the helicopter overload starting device It is mainly used to sense abnormal changes in the acceleration of the helicopter, and output an overload trigger signal to other equipment on board when overload occurs. [0003] The existing overload triggering device is generally fixed in a fixed installation position, and will not be calibrated and adjusted according to different models and installation errors. In addition, the helicopter may experience a...
