Integrated Gate Machine Controller On Elevator Automatic Door Opener Application Research

Elevator doors and users come into contact,opening and closing frequently,and therefore requested the doors open and closing fast,smooth movements,and no impact in the open and closed.Meet these performance requirements and the key is to control the gate drive motor speed to the required speed curves.In this paper,detailed analysis of the elevator door control system of critical technologies. Brushless DC motor of the working principle and its mathematical model of Adaptive Speed Control System BLDCM the characteristics of the adaptive choice BLDCM Speed Control System.View of the current market for the majority of the existing gate used PLC + inverter control,higher costs and operating results generally in favour of integration gate controller will be integrated with the control.and drive,control and drive through part of the communication protocol Transfer orders,no longer controlled by terminal type binary code, such theoretically can set any number of paragraphs and processing speed deceleration time, and can be opened and closed condition separately,using different V / F curves are controlled door and closed,to open the door at the moment,closed torque small,reliable can open the door closed to prevent power can ensure that the country does not exceed demand.Can effectively reduce costs and facilitate debugging a good effect,raise the grade,and good social and economic benefits.
