Abstract

The invention discloses an elevator system based on current control, comprising a microprocessor, a current detection controller, a power convertor, a command receiving module, a driving module, an electric motor, a tractor and a lift car, wherein a speed sensor is arranged on a rotating shaft of the electric motor; an output end of the microprocessor is connected with input ends of the current detection controller and the driving module respectively; the output ends of the current detection controller and the driving module are respectively connected with an input end of the power convertor;an output end of the power convertor is connected with input ends of the electric motor and the current detection controller respectively; an output end of the speed sensor is connected with an inputend of the microprocessor; an output end of the electric motor is connected with an input end of the tractor; the tractor is connected with the lift car by a hauling rope; and an output end of the lift car is connected with the command receiving module in series and then is connected with the input end of the microprocessor. The lift car in the elevator system has the advantages of steady operation and good acceleration effect.

Description

technical field [0001] The invention relates to the technical field of an elevator system based on current control. Background technique [0002] Conventionally, in order to keep the output of a hoisting machine that moves the car within a predetermined range, an elevator apparatus has been proposed that changes the acceleration / deceleration of the car in accordance with the ride load of the car. The car is provided with a weighing device for detecting the ride load. When the riding load is higher than a predetermined load (set value), the acceleration / deceleration of the car is reduced by the control of the control device (see Patent Document 1). [0003] Patent Document 1: Japanese Patent Laid-Open No. 2004-137003 [0004] However, for example, due to the movement of passengers in the car, errors are likely to occur in the detection of the riding load by the scale device. Therefore, in order to prevent the output of the hoisting machine from falling outside the predeter...
