Abstract

The invention belongs to the electromechanical control technology of aviation emergency escapement instruments, and relates to a reserve parachute opening control device. The reserve parachute control device comprises a pressure sensor, a controller and a cutting device, wherein the pressure sensor, the controller and the cutting device are sequentially connected in series through cables. The pressure sensor can feel the change of atmospheric pressure, convert the pressure value into an electrical signal and transmit the electrical signal to the controller. The controller can receive the pressure value electrical signal transmitted by the pressure sensor, calculate the pressure altitude and the falling speed of a parachute, and output a control signal to the cutting device. The cutting device is connected with a contraction rope of a reserve parachute and used for cutting off the contraction rope when receiving the control signal. The reserve parachute opening control device can judge whether the main parachute is opened or not according to the pressure altitude and the falling speed of the parachute, and automatically open the reserve parachute when the main parachute is not opened, and therefore casualties caused when the parachute manual opening can not be achieved can be avoided.

Description

technical field [0001] The invention belongs to the electromechanical control technology of aviation lifesaving instruments, and relates to a backup parachute opening control device. Background technique [0002] Present certain backup type parachute does not have automatic parachute opening device, is to manually open backup parachute bag, realizes parachute control. Its shortcoming is: when main parachute can not open parachute because of breakdown, airborne soldier can not manually open backup parachute because of the influence of factors such as physiology, psychology when skydiving, thus causes casualty accident. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a backup parachute opening control device, which can automatically open the backup parachute when the main parachute is not opened. [0004] In order to solve the above-mentioned technical problems, the overall technical idea of ​​the present inventio...
