Elevator door motor control device capable of automatically identifying door quality

Abstract

The invention discloses an elevator door motor control device capable of automatically identifying door quality. The device comprises a door motor controller, a motor, a transmission mechanism and a door motor load connected in sequence; the door motor controller comprises a motor control unit, a motor signal acquiring unit, an acceleration generation unit and a quality identifying unit; the motor control unit and the motor signal acquiring unit are connected with the motor; the quality identifying unit is connected with the motor signal acquiring unit, the motor control unit and the acceleration generation unit; and the acceleration generation unit is also connected with the motor control unit. After the device acquires electric parameters of the motor to obtain the door quality through the motor control unit, the motor signal acquiring unit, the acceleration generation unit and the quality identifying unit, the speed control and the self-adaption control can be performed on the motor according to the door quality, so that the excellent speed response and torque response of a motor speed adjusting system are realized, and meanwhile, the self-adaption control over the door motor is realized.

Description

technical field [0001] The invention relates to an elevator door machine controller, in particular to an elevator door machine control device for automatically identifying door quality. Background technique [0002] Today, the comfort and safety of elevator door operators are becoming more and more important, and the diversification of elevator doors is becoming more and more obvious. Just as an elevator has landing doors with different appearances or decorations, that is, the same elevator has different landing door qualities. , and even the mechanical structure of different floor doors is very different. [0003] The elevator national standard has strict requirements on the closing force of the elevator door to prevent the occurrence of pinching incidents during the door closing process. However, because the door drive system in the elevator only exists on the car door machine, for the landing doors of different floors, if the door quality is not the same, the required do...
