The invention discloses a multi-stage automatic parachute opening method of a parachute opening device, which comprises the following steps: S1, after a parachuting person leaves a cabin for parachuting, when the parachute opening device detects that the ground clearance of the parachuting person is reduced to an early warning height H1 and the current descending speed is greater than the early warning speed S1, the parachute opening device sends early warning information to a ground base station; s2, the ground personnel judges whether to open the standby parachute of the parachuting personnel through manual remote control according to the early warning information and experience; s3, if the ground personnel do not operate to open the standby parachute, when the ground clearance of the parachuting personnel continues to be reduced to the automatic parachute opening height H2, the parachute opening device detects that the current descending speed is larger than the automatic parachute opening speed S2, and the duration time reaches T2, the parachute opening device automatically controls the standby parachute to be opened; multi-stage parachute opening control is set, the height and the speed serve as main judgment conditions, active intervention of ground personnel is introduced, the parachute opening time accuracy of the standby parachute is improved, and safety is improved.
本发明公开一种降落伞开伞器的多级自动开伞方法,包括以下步骤:S1、跳伞人员出仓跳伞后,开伞器检测到跳伞人员的离地高度降低至预警高度H1,且当前下降速度大于预警速度S1时,开伞器向地面基站发出预警信息;S2、地面人员根据预警信息和经验判断,是否手动遥控打开跳伞人员的备用伞;S3、若地面人员未操作打开备用伞,则当跳伞人员的离地高度继续降低至自动开伞高度H2,开伞器检测到当前下降速度大于自动开伞速度S2,且持续时间达到T2时,开伞器自动控制备份伞打开;本发明设置多级开伞控制,以高度和速度作为主要判定条件,引入地面人员主动干预,提高备用伞开伞时间准确率,提高安全性。
