The invention discloses a dynamic compactor rammer height detection system. When a pressure value of a clutch is larger than or equal to a first preset pressure value, a winch starts to rotate, whether a growth rate of actual output torque of an engine within a preset time period is larger than a preset value or not is judged, if the growth rate of the actual output torque of the engine within thepreset time period is larger than the preset value, the current moment serves as a lifting zero position with a lifting height of a rammer being zero, an actual lifting height of the rammer is recorded through a pulse signal of a pulse sensor, and the system is simple in structure and convenient to set and maintain. The system judges the lifting zero position by acquiring the actual output torqueof an engine control unit to obtain the actual lifting height of the rammer, so that a braking time point of automatic braking can be accurately judged, and the system is low in cost and easy to maintain. The invention further discloses a dynamic compactor automatic detection system and a dynamic compactor, which comprise the dynamic compactor rammer height detection system and have the above technical effects.

    本发明公开了一种强夯机夯锤高度检测系统,当离合器压力值大于等于第一预设压力值时,卷扬开始转动,判断发动机实际输出扭矩在预设时间段内的增长率是否大于预设值,若是,则将当前时刻作为夯锤提升高度为零的提升零位,并通过脉冲传感器的脉冲信号记录夯锤实际提升高度,其结构简单便于设置及维护。上述系统通过采集发动机控制单元的实际输出扭矩判断提升零位,得到夯锤实际提升高度,进而能够准确判定自动刹车的刹车时间点,成本低,易维护。本发明还公开了一种包括上述强夯机夯锤高度检测系统的强夯机自动检测系统及强夯机,具有上述技术效果。
