Abstract: An elevator door control system, an elevator system, and an elevator door control method based on to-be-carried object grouping identification. The elevator door control system includes one or more three-dimensional sensors, arranged to capture three-dimensional data of to-be-carried objects in an elevator waiting region, wherein the three-dimensional data includes depth data; a data processing device, communicating with the three-dimensional sensor, and configured to receive and process the three-dimensional data, to provide grouping data of one or more groups obtained according to correlations between the to-be-carried objects and position data of each to-be-carried object in the elevator waiting region; and a control device, connected to an elevator door, communicating with the data processing device, and configured to control operation of the elevator door according to the grouping data and the position data.

Abstract: An illustrative example elevator assembly includes a frame having vertically oriented beams and horizontally oriented beams connected to the vertically oriented beams. A first elevator cab is supported within the frame between the vertically oriented beams. A pantograph linkage includes a plurality of links. The pantograph linkage is supported on one of the horizontally oriented beams. The pantograph linkage is connected with the first elevator cab such that different positions of the first elevator cab relative to the frame correspond to different relative positions of the links. A second elevator cab is suspended by the pantograph linkage beneath the frame. The different relative positions of the links place the second elevator cab in different positions relative to the frame.

Abstract: The present invention relates to a system for monitoring an elevator door, an elevator system, and a method for monitoring an elevator door. The elevator door has an open state or a closed state implemented by moving along an elevator sill. The system for monitoring an elevator door includes: one or more imaging sensors configured to collect image data and depth data of at least one section in the elevator sill that is exposed when the elevator door is in the open state; and a data processing device in communication with the imaging sensor and configured to receive and process the image data and the depth data to determine whether an obstacle preventing the elevator door from entering the closed state exists in the section. By applying the present invention, the safety of the elevator door can be improved effectively, and equipment property losses and personal injuries can be avoided.

Abstract: An illustrative example elevator assembly includes a header beam and a first elevator cab supported by the header beam. A plurality of vertically oriented rods extend beneath the first elevator cab. A horizontally oriented mid-beam is coupled to a first one of the rods near a first end of the mid-beam and coupled to a second one of the rods near a second end of the mid-beam. A second elevator cab is situated beneath the first elevator cab and beneath the mid-beam. At least one linear actuator is supported at least partially on the mid-beam. The linear actuator selectively causes vertical movement of the second elevator cab relative to the rods.

Abstract: A system for elevator door sensor fusion, fault detection, and service notification is provided. The system includes a processor and a memory including computer-executable instructions that, when executed by the processor, cause the processor to perform operations. The operations include monitoring outputs of a plurality of sensors. It is determined whether the outputs of the plurality of sensors follow an expected pattern. Based at least in part on determining that the outputs of the plurality of sensors do not follow the expected pattern: identifying a sensor in the plurality of sensors that is not following the expected pattern, and transmitting a notification indicating that the sensor is exhibiting unexpected behaviour.
