Methods and systems to control an elevator door of an elevator car that can be moved between floors of a building. At least one registered destination call is evaluated, which makes it possible to plan the number of boarding or exiting passengers for each stopping floor. For each stopping floor, a corresponding door dwell time for the elevator door is determined to make it possible for a registered passenger to board or exit on a stopping floor. The number of passengers that exit the elevator car on the stopping floor and the number of passengers that board the elevator car on the stopping floor is also determined. The elevator door is closed regardless of the set door dwell time if the number of passengers boarding and exiting on the stopping floor determined by the sensor system corresponds to the number of boarding or exiting passengers planned for the stopping floor.

An elevator control method, apparatus, and system, and an electronic device. The elevator control method includes: receiving a notification message, the notification message carrying a target moment, and the target moment being a moment at which an elevator door opens, or being a preset moment before the elevator door opens; performing a preset operation for instructing a driverless smart device to enter/exit an elevator in a case of determining, based on the target moment carried by the notification message, that a preset condition is met; and instructing an elevator control device to call the elevator in a case of determining, based on the target moment carried by the notification message, that the preset condition is not met.

According to one embodiment, a user detection system includes a camera, a boundary detector, a user detector and a controller. The camera is installed in a peripheral region of a door, and captures a running region when opening or closing the door and a region near the door. The boundary detector detects a boundary between a first structure and a second structure in the region near the door based on an image captured by the camera. The user detector detects whether there is a user in the running region based on a result detected by the boundary detector. The controller controls an open/close operation of the door based on a result detected by the user detector.

An elevator door safety system has a motion sensor and a proximity or door sensor defined in a fire-rated elevator entrance assembly. The sensors work together to determine when to open a closing door. The invention further defines a method of controlling an elevator door providing a motion sensor and providing a door sensor, wherein signals from each sensor are sent to a control board to determine when to open elevator doors in response to detecting a person in a detection area in an elevator entrance area.

A zone object detection system including a passenger compartment. Also included is a door moveable between an opened position and a closed position. Further included is a first sensor monitoring a first zone outside of a plane of the door. Yet further included is a second sensor monitoring a second zone comprising at least one of the plane of the door and outside of the plane of the door. Also included is a controller in operative communication with the first sensor and the second sensor, the controller commanding a first modification of a door closing movement of the door if an object is detected in the first zone, the controller commanding a second modification of the door closing movement of the door if an object is detected in the second zone.

An elevator monitoring system and method includes cabin-based radars monitor doors and passengers within a cabin; waiting zone radars monitor passengers in a waiting zone; a central processor analyzes data from the various monitors and executes an elevator control function to control the elevator system. The door state is determined by detecting reflections from internal angles within the cabin and a door management system manages door operation safely by monitoring a proximal zone around the automatic door, detecting moving objects and obstructions.
