An elevator system, having: a hoistway, a pit; a car; a sensor assembly, configured to capture and process images, configured to form a VSN around a first area that is exterior to the car, a safety chain configured to: monitor a change in positioning of a stationary object that is external to the car to determine a measured speed of the car, and upon detecting that an object has breached the VSN, the sensor assembly is configured to: select a first response protocol, from a set of response protocols that are correlated to different measured speeds of the car; and execute the first response protocol.

An exemplary building sway operation system (10) for an elevator includes an acceleration sensor (11), and a data receiving unit (12) for receiving a sensor output from the acceleration sensor (11). The acceleration sensor (11) is designed to be mounted on a movable mass (6) of an active vibration control device (5) for a building, in order to detect the reciprocating motion of the movable mass (6) of the active vibration control device (5) responsive to the occurrence of earthquakes or strong winds.

A service alarm device for use in an elevator system, the service alarm device including a control board configured to receive at least one safety signal, and an alarming device in communication with the control board, wherein the control board is configured to activate the alarming device based on the at least one safety signal.

An elevator system having an elevator car, at least one sensor, wherein, the system is configured to: receive sensor data from the at least one sensor that is indicative of a first passenger calling or within the elevator car, determine from the at least one sensor data a travel intent of the first passenger, and take an action when the travel intent triggers an alert condition.

Techniques for automatically modifying elevator workflow based on incident type are provided. An incident occurring within an elevator is detected via a video camera. Video analytics are used to determine the incident type. It is determined that a floor selection associated with the incident type will place elevator passengers or people on the selected floor at risk. Elevator workflow execution is automatically modified based on the incident type and risk associated with the floor selection. The floor selection is displayed while modifying the elevator workflow to a different floor. A security notification indicative of the incident type and the automatic modification of the elevator workflow is sent.

Provided is a multi-car elevator system including: a plurality of cars to be raised and lowered in the same hoistway; and an inspection work controller. The inspection work controller is operated by a worker so as to move an operation target car which is one of the plurality of cars. Further, the operation target car is allowed to be selected from two or more of the cars in a work area in which the worker is present.
