Automatic braking method and system for dynamic compaction machine
The invention discloses an automatic braking method and system for a dynamic compaction machine. The automatic braking system comprises a pressure detection device arranged on a clutch and used for detecting a pressure value of the clutch, a displacement detection device arranged on a main winch of the dynamic compaction machine and used for detecting the displacement of the main winch, and a maincontrol device connected with the pressure detection device and the displacement detection device; and the main control device is connected with an engine control unit to obtain the actual output torque of an engine, the main control device judges whether the increasing rate of the actual output torque of the engine is larger than a preset value within a preset time interval or not when the pressure value of the clutch of the pressure detection device is larger than or equal to a first preset pressure value, if yes, a current moment serves as a lifting zero position with the compaction lifting height being zero, and the actual lifting height of a rammer is recorded according to a replacement signal of the displacement detection device. According to the automatic braking method and system,the lifting zero position is judged by collecting the actual output torque of the engine control unit, the actual lifting height of compaction is obtained, thus a braking time point of automatic braking can be accurately judged, the cost is low, and maintenance is easy.
本发明公开了一种强夯机自动刹车方法及系统，包括设于离合器上用于检测离合器压力值的压力检测装置；设于强夯机主卷扬上用于检测主卷扬位移的位移检测装置；分别与压力检测装置和位移检测装置连接的主控装置，主控装置与发动机控制单元连接以获取发动机实际输出扭矩，主控装置当压力检测装置的离合器压力值大于等于第一预设压力值时，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，并根据位移检测装置的位移信号记录夯锤实际提升高度。其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。
