Embodiment 1

[0033] Embodiment 1 This embodiment discloses a safety protection method for autonomous parachute opening of a small aircraft (for details, see figure 1 ), the process of the method includes:

[0034] First, the system is initialized, and the definition and assignment of each variable and constant are completed; then enter step S0,

[0035] S0: System self-inspection, if the system is normal, enter step S1, otherwise end;

[0036] S1: Obtain altitude information parameters and read altitude signals;

[0037] S2: Signal preprocessing, taking the average value of 10 times of sampling data as the input value of the subsequent algorithm, judging whether the height parameter reaches the preset value, if it reaches the preset value, then proceed to S3, if the height does not reach the preset value, then return to step S1;

[0038] S3: Read flight attitude parameters and power battery power parameters;

[0039] S4: Signal preprocessing, taking the average value of 10 sampling dat...

Abstract

The invention belongs to the technical field of aircraft control and particularly relates to an autonomous parachute opening safety protection method and system for a small aircraft. A reliable safety protection algorithm is provided, the flight height, the flight attitude and system electric quantity are used as input variables, a gas generator detonation control command and a power source management command are used as output variables, meanwhile, the flight attitude and system electric quantity information affecting system safety work are taken into consideration, meanwhile, a denotation signal and power electricity are controlled, and safety is improved. The principle is simple, and no matter in the aspects of software implementation or hardware implementation, no obstacles exist. The system is simple in structure, easy to implement and low in cost. The threat caused by flight attitude unstability to flight safety is fully considered, the threat caused by too low electric quantity to flight safety is considered as well, meanwhile, damage possibly caused by an unfolded canopy to rotors is considered, and the effectiveness of the system is fully improved. The method and system have great market prospects and economic value.

Description

technical field [0001] The invention belongs to the technical field of aircraft control, and in particular relates to a safety protection method and system for autonomous parachute opening of a small aircraft. Background technique [0002] In the use of small aircraft, it is always inevitable to encounter dangerous situations such as low battery and unstable attitude. The crash of an aircraft will always cause serious damage to the aircraft itself, and the damage to the airborne equipment is also inevitable. Furthermore, the adverse impact on the mission is difficult to estimate. In response to such problems, most of the existing safety protection technologies adopt low-battery alarms, autonomous return and other processing measures. These methods are still based on the fact that the aircraft can continue to fly safely. The safety of the aircraft and airborne equipment cannot be guaranteed for the situation that the aircraft cannot continue to fly normally. There are stil...
