Problems solved by technology

However, when the door machine controller is powered off, the speed of closing the door by an external mechanical device is uncontrollable, which is prone to jamming
[0004] The door machine controller and the elevator main board transmit the door opening and closing signals through external terminal signals. However, once there is a problem with these signals, there will be a situation similar to the power failure of the input power, and the door will become closed, and there may be a jamming situation.

Embodiment Construction

[0028] Such as figure 1 Shown is a flow chart of an elevator door machine control method in an embodiment. The method includes the following steps.

[0029] Step S101: Detect whether the door opening and closing instruction signal is transmitted normally. The door opening and closing command signal is the command signal about opening and closing the elevator door sent by the elevator controller to the door machine controller. During the door opening and closing process of the elevator, the door opening and closing command signal is continuously output until the door is fully opened (at this time, the door open hold signal) or the door is completely closed (the door close hold signal is output at this time).

[0030] There is a signal path between the elevator controller and the door machine controller. If the signal path fails, it will cause abnormal transmission of the door opening and closing command signal. Certainly, the transmission abnormality of the door opening and ...

Abstract

The invention discloses an elevator door motor control method. The method includes the steps of detecting whether or not a door closing or opening command signal is normally transmitted; if the door closing or opening command signal is lost, providing a speed ring in a door motor controller with preset speed; adjusting the speed ring to provide a current ring in the door motor controller with current; subjecting the current ring to power amplification by a regulating power amplifier, subjecting the speed ring and the current ring to feedback regulation by an encoder so as to maintain the provided speed. The elevator door motor control method has the advantages that whether or not the door closing or opening command signal is normally transmitted is detected; when the door closing or opening command signal is lost, the speed ring is provided with the preset speed; an elevator door can be closed at the provided speed, and pinching due to the elevator door being closed fast under control of external mechanical devices is prevented.

Description

technical field [0001] The invention relates to the technical field of elevator control, in particular to an elevator door machine control method. Background technique [0002] In recent years, the frequency conversion door machine has been widely used, and the permanent magnet synchronous direct drive door machine has an increasing share in newly installed elevators due to its own advantages such as simple transmission structure and high efficiency. [0003] The permanent magnet synchronous direct drive door operator system can ensure that when the door operator opens the door, even if the door operator controller is powered off, the elevator door can be turned into a closed state by an external mechanical device (usually a spring + weight). However, when the door machine controller is powered off, the speed of closing the door by an external mechanical device is uncontrollable, which is prone to jamming. [0004] The door machine controller and the elevator main board tra...
