Digital positioning landing control device

Abstract

The invention discloses a digital positioning landing control device, which comprises a height, direction and distance signal acquisition unit, a computer control operator, a signal amplifier, a servo mechanism and an operating component. The control process comprises the following steps of: dropping a parachute; measuring the height, and determining to open the parachute; starting a control device; calculating azimuth difference and distance difference between parachute direction and the set dropping point; transmitting a digital control signal; amplifying the signal; driving a stepping motor, and dynamically operating the adjustment of a direction angle of the parachute; landing the parachute and closing the servo mechanism; turning on a position signal transmission and lamp display component; and automatically acquiring summarized data of landing supplies through the computer. The control device is applied to complex terrains and areas which personnel difficultly accesses, and is applied to accurately dropping supplies through the parachute, dropping the supplies at fixed points under unmanned operation, and the like.

Description

technical field [0001] The invention relates to a digital positioning and landing control device, which is especially suitable for the precise fixed-point landing control of materials dropped in the air. Background technique: [0002] At present, the landing device for delivering materials still mainly adopts the uncontrolled free falling method for delivery. For complex landforms such as mountains and forests, as well as meteorological conditions such as clouds, fog, and wind, and nuclear disasters that require unmanned operation and other harsh environments, this divergent free-falling parachute delivery method is difficult and fast. , Accurately complete the task of putting in emergency rescue and relief materials, and while delaying the fighter plane, it also paid a heavy price. In the many natural disasters in recent years, such as the Wenchuan Earthquake, our airborne troops had to risk their lives to parachute to the core area of ​​the earthquake-stricken area to del...
