Excavator dynamic weighing method and system
The invention provides an excavator dynamic weighing method and system and relates to the technical field of excavator weighing. The excavator dynamic weighing method comprises steps that a first parameter, a second parameter and a third parameter are detected; the first parameter is an included angle formed by a connecting line of the mass center of a movable arm and the first hinge point relative to the vehicle body or a first telescopic amount of a movable arm oil cylinder; the first hinge point is a hinge joint of the movable arm and the vehicle body; the second parameter is an included angle formed by a connecting line of the mass center of a bucket rod and the first hinge point relative to the vehicle body or the expansion amount of a bucket rod oil cylinder; the third parameter is an included angle formed by a connecting line of the mass center of a bucket and the first hinge point relative to the vehicle body, or the expansion amount of the bucket oil cylinder; and the weight mass is obtained according to the first parameter, the second parameter, the third parameter and the pressure intensity in a large cavity of the movable arm oil cylinder.
本发明提供了一种挖掘机动态称重方法及系统，涉及挖掘机称重的技术领域，所述挖掘机动态称重方法包括：包括以下步骤：检测第一参量、第二参量和第三参量；第一参量为动臂的质心与第一铰点的连线相对于车体的形成的夹角，或者为动臂油缸的第一伸缩量；其中，第一铰点为动臂与车体的铰接处；第二参量为斗杆的质心与第一铰点的连线相对于车体的形成的夹角，或者为斗杆油缸的伸缩量；第三参量为铲斗的质心与第一铰点的连线相对于车体的形成的夹角，或者为铲斗油缸的伸缩量；根据第一参量、第二参量和第三参量，以及动臂油缸大腔内的压强，获得重物质量。
