本发明公开了一种动态爆心定位方法及系统。该方法包括：获取待定位的爆心的初始坐标；获取地面测点坐标、装药速度以及装药量；根据爆心的初始坐标、地面测点坐标、装药速度以及装药量，计算初始壁面反射超压；判断初始壁面反射超压与实际壁面反射超压的差值是否在预设范围内；若是，确定爆心的初始坐标为爆心坐标；若否，通过莱文-马夸特方法更新爆心的初始坐标。本发明以测点冲击波超压值作为原始数据，以自由场冲击波传播规律、壁面反射规律等建立求解方程组，计算壁面反射超压，根据动态爆炸试验中测点地面冲击波超压、测点相对位置坐标和爆心三维坐标之间的函数关系，定位爆心坐标，提升了空中动态爆炸在爆心定位过程中的精度和自动化程度。 The invention discloses a dynamic blasting center positioning method and system. The method comprises the following steps: obtaining an initial coordinate of a to-be-positioned explosion center; Obtaining a ground measuring point coordinate, a charging speed and a charging amount; Calculating initial wall reflection overpressure according to the initial coordinates of the explosion center, the coordinates of the ground measuring point, the charging speed and the charging amount; Judging whether the difference between the initial wall surface reflection overpressure and the actual wall surfacereflection overpressure is within a preset range or not; If yes, determining the initial coordinate of the explosion center
