摘　　要：装载机动态称重装置是依据对现有装载机数学模型的分析及装载机油压和重量在特定区间具有线性对应关系的特点来完成的.硬件电路选用ARM处理器,AD7730高精度的A\D转换芯片;软件上使用Akima插值算法及最小二乘曲线拟合方法实现了对实测数据的滤波、插值计算、数据平移补偿等功能,通过实验验证该装置满足装载机动态称重系统的控制要求.The dynamic weighing device of the loader designed in this paper is based on the analysis of the existing mathematical model of the loader and the linear relationship between the oil pressure and the weight of the loader in a specific interval. The hardware circuit uses ARM processor, AD7730 high-precision A\D conversion chip;the software uses the Akima interpolation algorithm and the least-squares curve-fitting method to realize the filtering, interpolation calculation, data translation compensation and other functions of the measured data, and the device meets the control requirements of the dynamic weighing system of the loader through experiments.
