Unattended automatic grabbing, hanging and transporting device and method for helicopter

Abstract

The invention discloses an unattended automatic grabbing, hanging and transporting device and method for a helicopter. The method comprises a target placing method, an identifying and positioning method, an automatic grabbing method, a hanging monitoring method and a throwing and unloading method. Under the condition that a manned helicopter or an unmanned helicopter is unattended on the ground, targets connected with goods are grabbed and hung by means of a target recognition and positioning system, then goods hanging and transporting are completed, and the method and the method are low in manual participation degree, high in safety and the like.

Description

technical field [0001] The invention belongs to the field of helicopter external hanging transportation, and in particular relates to an unattended automatic grabbing and hanging transportation device and method for a helicopter. Background technique [0002] Before the helicopter performs cargo external hanging transportation, it is necessary to hang the rigging connected with the cargo on the hook of the cargo hook device. Existing suspension method has two kinds: a kind of suspension method is that helicopter lands on the ground, and cargo is placed on the side of helicopter, and sling is suspended on the hook of cargo hook device manually, and helicopter takes off, and hangs cargo transportation flight. This method has the following problems: 1. It is necessary to adjust the distance between the cargo and the helicopter. It is necessary to ensure that the rotor does not collide with the cargo, and it is necessary to ensure that the rigging is suspended manually; 2. The l...

AI Technical Summary

Problems solved by technology

This method has the following problems: 1. It is necessary to adjust the distance between the cargo and the helicopter, not only to ensure that the rotor does not collide with the cargo, but also to ensure that the rigging is suspended manually; Small and small, it is inconvenient to mount manually; 3. When the helicopter takes off, if the attitude is not adjusted in time, it is easy to be pulled by the side of the rigging, causing a safety accident

This kind of method has the following problems: 1, the helicopter needs to reduce the height as much as possible so that the operator can hang the rigging. At this time, once it is affected by the environment such as crosswind, the helicopter will be difficult to control and cause a safety accident; 2, the flight process of the helicopter The center will generate a maximum voltage of 300kV, which is easy to injure people by electric shock; 3. The wind generated by the rotation of the helicopter rotor is relatively strong, which may cause injury to the suspension rigging personnel
