Referring to fig. 2, an elevator car door according to an embodiment of the present invention is provided with an elevator car door flatness detecting device and an elevator car door straightening device. The elevator car door is driven by the door motor to switch between an open state and a closed state, for example, in the embodiment of the invention, the elevator car door flatness detection device is preferably arranged at one end of the top of the elevator car door, which is positioned in the middle of the elevator, so that the inclination information of the elevator car door in the running process can be more clearly collected. In the embodiment of the invention, the elevator car door flatness detection device can be any one of a 9-axis gyroscope, an infrared sensor and an ultrasonic sensor, and can be connected with an elevator control system in a wired or wireless connection mode.
In the practical application process, in order to reduce energy consumption in the monitoring and correcting process of the elevator car door and prolong the service life of the elevator car door flatness detection device, before the inclination information of the elevator car door is obtained, an elevator control system monitors whether the current elevator obtains a door opening signal or a door closing signal in real time, for example, at a certain moment, after a user enters the elevator, the user clicks a door closing button on an operation panel to send a door closing instruction to the elevator. At the moment, after receiving the door closing instruction, the elevator control system obtains the inclination information of the elevator car door in real time through the elevator car door flatness detection device, wherein the inclination information comprises information such as the running track and the inclination angle of the elevator car door.
After the inclination information is obtained, the elevator control system immediately generates a corresponding correction control instruction, for example, the elevator control system can compare the inclination information with normal operation information to generate a corresponding correction control instruction, and sends the correction control instruction to the elevator car door correction device. After the elevator car door correction device obtains the correction control instruction, corresponding correction control operation is executed, and therefore correction control over the car door is achieved.
In the embodiment of the invention, the elevator car door is additionally provided with the elevator car door flatness detection device and the elevator car door correction device, so that the inclination information of the elevator car door in the door closing process is acquired and monitored in real time, and once the elevator car door is abnormal, the elevator car door can be timely acquired and timely processed, so that the condition that a user cannot use or an accident happens due to the abnormal elevator car door is effectively avoided, and the user experience is improved.

Referring to fig. 4, in a possible embodiment, in the process of acquiring the inclination information of the elevator car door in real time, a three-dimensional coordinate system based on the elevator car door is first established, for example, the three-dimensional coordinate system based on the elevator car door is established with one end of the elevator car door, which is located at the edge of the elevator, as an origin of coordinates, the direction of the elevator car door closing as an X axis, the direction perpendicular to the X axis in a horizontal plane as a Y axis, and the direction perpendicular to a plane formed by the X axis and the Y axis as a Z axis.
After the operation information in the three directions is obtained, the elevator control system further obtains initial positions of the elevator car door in the three directions, for example, in the embodiment of the present invention, the initial position of the elevator car door is a coordinate origin, that is, the initial X position, the initial Y position, and the initial Z position are all coincident and located at the coordinate origin, further, corresponding X-axis operation trajectory, Y-axis operation trajectory, and Z-axis operation trajectory are generated according to the obtained operation information in the three directions, at this time, correction analysis is performed on the three-axis operation trajectory, for example, whether a certain position of the elevator car door on each axis is too sunken or too much lifted is analyzed, if too sunken or too much lifted is performed at the position, a reverse control instruction in the position is immediately generated to counteract the sunken or lifted, that is, a control instruction of the elevator car door is generated, so as to realize smooth operation control of the elevator car door.
In the embodiment of the invention, the three-dimensional coordinate system is established based on the elevator car door, and the running information of the elevator car door in three directions in the door closing process is collected and analyzed in real time, so that the accurate inclination information of the elevator car door is generated, the abnormity of the elevator car door can be monitored in time according to the inclination information in the directions, and the abnormity can be analyzed and processed in time once the abnormity occurs, so that the elevator stopping or fault caused by the abnormity of the elevator car door is effectively reduced, the influence on the normal use of a user is greatly reduced, and the user experience is improved.
