Method and system for acquiring elevator loads

The invention discloses a method and system for acquiring elevator loads. The method comprises the following steps that load information measured by a weighing device is acquired; revised loads corresponding to acquired load information are mapped out according to corresponding relations of prearranged revised loads of an elevator car and the load information measured by the weighing device; the revised loads which are mapped out are set as actual loads of the elevator car. The method and system for acquiring the elevator loads can effectively reduce load errors caused by the defective workmanship of an elevator and provides an accurate load basis for operations such as starting torque placing or giving of all kinds of replying orders of the elevator.
