The invention discloses an aircraft low-altitude flight high-voltage line danger approach detection method and system. A flight area high-voltage line mathematical model is established; the position information of the current aircraft is obtained, the position information comprises the flight height and longitude and latitude coordinates, whether the longitude and latitude of the current aircraft are located between the maximum latitude and the minimum latitude and between the maximum longitude and the minimum longitude of the high-voltage line segment where the current aircraft is located or not is judged, if yes, high-voltage line danger approaching detection is started, and if not, the height is regarded to be safe; when high-voltage line danger approaching detection is started, whether the current flight height of an aircraft is lower than the vertical alarm height of a high-voltage line segment is judged firstly, if yes, horizontal danger approaching alarm detection is started, and if not, the height is regarded to be safe; when horizontal danger approaching alarm detection is started, the minimum horizontal distance between the current aircraft and the high-voltage line segment where the aircraft is located is calculated, when the minimum distance is smaller than a horizontal early warning or alarm distance, high-voltage line danger approaching early warning or alarm is given out, and if not, the height is regarded to be safe.
本发明公开了一种航空器低空飞行高压线危险接近检测方法及系统,建立飞行区域高压线数学模型;获取所述当前航空器的位置信息,位置信息包括飞行高度和经纬度坐标,判断当前航空器经纬度是否位于所在高压线线段的最大纬度和最小纬度、最大经度和最小经度之间,若在此范围,则启动高压线危险接近检测,否则,视为安全;启动高压线危险接近检测时,先判断当前航空器飞行高度是否低于所在高压线线段垂直告警高度,若低于垂直告警高度则启动水平危险接近告警检测,否则视为安全;启动水平危险接近告警检测时,计算当前航空器离所在高压线线段的最小水平距离,当此最小距离小于水平预警或告警距离,则发出高压线危险接近预警或告警,否则视为安全。
