摘要： An elevator system includes an elevator car, an elevator controller, a safety controller and a plurality of safety contacts connected to the safety controller, wherein the plurality of safety contacts monitor the elevator system. The safety controller is configured to receive individual status information from each of the plurality of safety contacts and to prevent movement of the elevator car when the individual status information received from one of the plurality of safety contacts indicates an unsafe condition of the elevator system. The safety controller is configured to connect to a remote computing device, to receive first authentication information from the remote computing device, and to authenticate the remote computing device if the first authentication information meets an authentication condition. If the remote computing device is authenticated, to permit the remote computing device to override the safety controller to enable movement of the elevator car.

摘要： Elevator system includes a hoistway extending between a plurality of landings; an elevator car configured for moving along the hoistway between the plurality of landings; an elevator drive configured for driving the elevator car; a position determining system configured for determining the position of the elevator car within the hoistway; at least one switch; and an elevator controller. The elevator controller is configured for detecting an activation of the at least one switch; controlling the elevator drive to move the elevator car in a predetermined direction after the switch has been activated; determining the current position of the elevator car within the hoistway and comparing the determined position of the elevator car with at least one predefined positional limit (LUP, LLOW), while the elevator car is moving.

摘要： Embodiments as disclosed herein provide a car operation panel for commanding travel of an elevator car from a boarding landing to a destination landing during normal operation of an elevator system. The car operation panel has a plurality of car operation switches to be operated by a passenger from inside of the elevator car during normal operation of the elevator system. The car operation panel is mechanically convertible such as to switch the car operation panel from a first configuration corresponding to the normal operation mode to a second configuration corresponding to an inspection and maintenance operation mode. The car operation panel, when switched to the second configuration, allows manual control of the elevator car to travel in up direction and/or in down direction by operating at least a part of the car operation switches of the car operation panel.
