The invention discloses an elevator car weighing method, which comprises the following steps that: a car and a counterweight are arranged in a hoistway, under the driving of a traction motor, a steel wire rope drives the car and the counterweight to move reversely along the vertical direction, and an absolute position sensor detects the total elongation delta L of a car load bearing mechanism caused by the change of the load weight in the car; and a load weight change value delta F in the lift car is calculated through a controller according to the total elongation delta L of the lift car load bearing mechanism. According to the elevator car weighing method, the actual load weight change value in the elevator car can be rapidly and accurately obtained.
本发明公开了一种电梯轿厢称重方法,轿厢及对重置于井道内,在曳引电机的驱动下,钢丝绳带动轿厢及对重沿竖向反向运动,通过绝对位置传感器检测出轿厢内负载重量变化导致的轿厢负载承载机构的总伸长量ΔL,通过一控制器根据轿厢负载承载机构的总伸长量ΔL计算得到轿厢内负载重量变化值ΔF。本发明的电梯轿厢称重方法,能快速准确的获得实际电梯轿厢内负载重量变化值。
