The invention relates to a weighing-device-free elevator system control method. By the adoption of the weighing-device-free elevator system control method, the problems that in the prior art, a weighing device is needed during elevator control, the weighing device needs to be debugged and calibrated, and thus the cost is increased, and manpower consumption and material consumption are high are solved. According to the technical scheme, on the basis of an existing elevator control system, the actual load of an elevator car of the elevator is obtained by monitoring torque currents of a main unit of an elevator and the variation of the torque currents, so that operation of the elevator is controlled. The weighing-device-free elevator system control method has the advantages that the actual load of the elevator car of the elevator is obtained by monitoring the torque currents of the main unit of the elevator and the variation of the torque currents, so that operation of the elevator is controlled; no weighing device needs to be installed on an elevator control system, the procedure of weighing the elevator car through the weighing device is omitted in the control process, the material cost of a traditional elevator weighing device is saved, installing and debugging of the weighing device are omitted, and the problem of faults of the weighing device are solved.
