The embodiment of the invention provides a helicopter ground proximity warning method and device, and the method comprises the steps: obtaining current flight parameter information of a helicopter, and determining the current flight height of the helicopter according to the flight parameter information; according to the flight height, determining an alarm model from an overlarge descent rate judgment model, an overlarge terrain approach rate judgment model, a post-takeoff drop height judgment model, an unsafe ground clearance judgment model, an overlarge roll angle judgment model, a tail ground collision judgment model and a forward-looking terrain alert model; and determining early warning parameters corresponding to the alarm model according to the flight parameters, and judging whetheran alarm instruction corresponding to the alarm model needs to be sent out or not according to the early warning parameters. According to the embodiment, the corresponding judgment model can be selected as the alarm model according to the flight height of the helicopter, so that alarm prediction can be carried out in a targeted manner, the data processing efficiency is improved, the operation timeis saved, and the real-time monitoring of the flight safety of the helicopter is realized.
本发明实施例提供一种直升机近地告警方法和装置,直升机近地告警方法包括:获取直升机当前的飞行参数信息,并根据飞行参数信息确定直升机当前的飞行高度;根据飞行高度,从过大下降率判断模型、过大地形接近速率判断模型、起飞后掉高度判断模型、非安全离地高度判断模型、过大侧倾角判断模型、尾部撞地判断模型、前视地形警戒模型中确定告警模型;根据飞行参数确定与告警模型对应的预警参数,并根据预警参数判断是否需要发出告警模型对应的告警指示。本实施例中可以根据直升机的飞行高度选择对应的判断模型作为告警模型,从而可以针对性的进行告警预测,提高了数据处理效率,节省了运算时间,实现直升机飞行安全的实时监控。
