The invention discloses a weighing system and method of a free portal forklift in the technical field of loading and unloading machinery. The system comprises a free portal and a sensing system. The free portal frame comprises a first lifting oil cylinder and a second lifting oil cylinder; the sensing system comprises an information measuring module and an information processing module; the information measuring module comprises a pressure sensor and an angle sensor; the pressure sensor is used for measuring pressure values of the first lifting oil cylinder and the second lifting oil cylinder; the angle sensor is used for measuring an inclination angle value of the free portal; the information processing module comprises a control sub-module and a display screen; the pressure value and the inclination angle value are transmitted to the control sub-module; the control sub-module calculates a preset parameter value through the pressure value, the preset parameter value is substituted into a preset calculation model, a weighing calculation formula is obtained, and a weight value is calculated; and the display screen is used for receiving and displaying the pressure value, the inclination angle value and the weight value transmitted by the control sub-module. Under the condition that a weighing processing module and a weighing displayer are not additionally arranged, the weighing function requirement of the forklift is met, and cost is saved.

    本发明公开了一种装卸机械技术领域的自由门架叉车的称重系统及方法,系统包括自由门架和传感系统;自由门架包括第一起升油缸和第二起升油缸;传感系统包括信息测量模块和信息处理模块;信息测量模块包括压力传感器和角度传感器;压力传感器用于测量第一起升油缸和第二起升油缸的压力值;角度传感器用于测量自由门架的倾角值;信息处理模块包括控制子模块和显示屏;压力值和倾角值传输至控制子模块;控制子模块通过压力值计算得预设参数值,代入预设计算模型,获得称重计算式,计算重量值;显示屏用于接收控制子模块传输的压力值、倾角值和重量值并显示。本发明能在不加装称重处理模块和称重显示器的情况下,满足叉车称重功能需求,节约成本。
