本文通过对龙门吊车称重信号的分析,导出了易于处理的数学模型。并简述了用于本处理系统的数字滤波器的设计,同时给出了用计算机实现的程序框图。通过多次现场实验表明,本处理系统达到实时显示的重量误差值<0.2%F·S·的设计要求
In this paper, we analyze the weighing signal of gantry crane and derive the mathematical model which is easy to handle. The design of the digital filter used in this system is also briefly described. At the same time, a block diagram of the program is given. Through many field experiments show that the processing system to achieve real-time display of the weight error value of <0.2% F · S · design requirements
