Abstract

The invention discloses an elevator system subjected to normal speed curve elevator door control. A portal crane controller mainly comprises a communication module, a switch, a DSP, a rectification module, an IPM inverter, a protection circuit, a drive circuit and a current detection module. The DSP uses a normal speed curve control manner to control opening and closing of an elevator door, so that the elevator door is not prone to happening collision when the elevator door runs to the end point during opening and closing; by detecting the distance and speed, the motor is controlled to make the elevator door run, be opened and be closed smoothly; and a normal speed curve is that the door closing speed change is in a shape of a curve in normal distribution.

Description

technical field [0001] The invention relates to the field of elevator systems, in particular to an elevator system controlled by a normal speed curve elevator door. Background technique [0002] The elevator door motor is a key part of the elevator system. However, in recent years, there have been more and more elevator safety accidents caused by the elevator door motor. According to relevant data, about 80% of elevator system failures are caused by elevator door motors, and more importantly, elevator door motors also cause 70% of elevator safety accidents. A large part of the reason for the accident of the elevator door machine is caused by the problem of the control system of the elevator door machine. The elevator door motor control system controls the opening and closing of the elevator door, and its performance directly affects the safety and stability of the elevator door motor. The elevator door motor is the equipment that passengers touch and operate, so its contro...
