Abstract
An elevator component separation assurance system includes a controller, and a brake controller. The controller includes an electronic processor, a computer readable storage medium, a safety motion state estimator, and a safety assurance module. The safety motion state estimator is configured to identify velocity and position of each one of a plurality of elevator components. The safety assurance module is configured to select a separation map from a plurality of pre-pre-programmed separation maps for each one of an adjacent component pair of the plurality of elevator components for initiating a Ustop that maintains elevator component separation. The brake controller is carried by each one of the plurality of elevator components, and is configured to actuate a secondary brake upon detection of a loss of communication with at least a portion of the controller.
