Methods and systems for determining elevator car locations are provided. Aspects includes a sensor affixed to a moving component of an elevator system, wherein the sensor is operated by a controller and wherein the controller is configured to determine that the elevator car is in motion based at least in part on the sensor. A direction of the elevator car is determined while the elevator car is in motion based at least in part on the sensor. Sensor data associated with the elevator car is collected while the elevator car is in motion, wherein the sensor data includes a travel time while the elevator car is in motion. Elevator car travel data is accessed from a travel time profile associated with the elevator car and the travel time is compared to the elevator car travel data to determine a location of the elevator car in a hoistway.

A system and method for detecting a brake dragging during normal operation of a motor monitors torque at zero speed and at constant speed. For an inertial system acted upon by gravity, a value of torque required to maintain zero speed is approximately the same as a value of torque required to maintain operation at a constant speed. In an exemplary, elevator system, a motor drive determines the torque required to maintain zero speed operation of an elevator cab after a holding brake opens and before it begins controlling the motor to rotate. The motor drive again determines the torque required to maintain a constant speed and compares this value to the value of torque required to maintain zero speed. If the difference between the two values of torque is greater than a predefined threshold, then the motor drive determines that the brake is dragging and sets an error message.

Elevator systems and methods of use including an elevator car located within an elevator shaft, at least one sensing device arranged within the elevator car, an elevator controller arranged to control at least one of an operating condition and at least one feature within the elevator car, and a computing system in communication with the at least one sensing device and the elevator controller, wherein the computing system is arranged to detect a passenger state of a passenger within the elevator car and configured to control the operating conditions and features within the elevator car based on the detected passenger state.

A pressurized fluid powered cabin-management system for an elevator system with a cabin and drive system is provided. The cabin-management system is configured to direct operation of the elevator system upon arrival of one of the cabins at a floor, and comprises a floor detector configured to detect when the cabin is located at a floor and to activate a timer. The timer is configured, when triggered, to activate a timing arrangement and to pass pressurized fluid to a control valve being in a first position. The timing arrangement is configured to direct the control valve to assume a second position after a predetermined amount of time. The cabin-management system performs, when pressurized fluid is passed to the control valve in its first position, actions for opening a door, and, after the control valve has assumed its second position, actions for travel of the cabin.

Elevator cars are provided herein. The elevator cars include a wall panel defining part of a passenger space of the elevator car, two or more receiving rails arranged on an exterior of the wall panel, and an elevator display system having a viewing panel and an enclosure housing a display screen. The viewing panel is mounted to the wall panel on an interior of the wall panel and the enclosure is engageable with the receiving rails on the exterior of the wall panel such that the display screen is movably positioned relative to the viewing panel to be viewable from within the passenger space in an installed position.

According to an aspect, there is provided an elevator car parking brake. An operating fork is configured to move within a housing in a direction perpendicular to an end surface of a guide rail in response to operating an actuator. When the actuator is operated to move the operating fork within the housing towards the guide rail to achieve a braking state, the operating fork is configured to push braking wedges towards side surfaces of the guide rail to contact the side surfaces. When the actuator is operated to move the operating fork within the housing away from the guide rail to achieve a brake release state, detaching means are configured to pull the braking wedges away from the side surfaces of the guide rail.

An elevator car guide wheel system includes a guide wheel located at an elevator car, configured to contact a guide rail of an elevator system. The guide wheel includes a wheel hub located at a guide wheel axis, a wheel rim, and a wheel outer portion located at the wheel rim and configured for contact with the guide rail. A magnetic element is located at the guide wheel, and a sensor is located at the guide wheel and is configured to detect rotational direction and rotational speed of the guide wheel about a guide wheel axis via detecting a magnetic field of the magnetic element.

Disclosed is an elevator system having a first sensor in communication with an elevator in a multi-level hoistway, wherein during an emergency the elevator instructs the first sensor to sense conditions and transmit sensor data representing the sensed conditions, and the transmitted sensor data is processed to obtain an image representing an intensity of hazard conditions on at least a subset of levels serviced by the multilevel hoistway.

An illustrative example embodiment of an elevator compensation assembly includes a tie down mechanism and at least one compensation sheave that has an outer surface configured to engage at least one compensation rope member. At least one damper is associated with the tie down mechanism for resisting vertical movement of the tie down mechanism in at least one direction. At least one detector directly detects vertical movement of the tie down mechanism along the direction and provides an output indicating at least one characteristic of the detected vertical movement.

A blockchain maintenance record system for managing maintenance records of a system, the blockchain maintenance record system including: a part identification tag configured to be located on a part; an application operable through a mobile computing device, the mobile computing device being configured to read the part identification tag, wherein the application is configured to perform operations including; determining a part identity of the part by reading the part identification tag; detecting a location of the system; organizing the part identity of the part and the location of the part into a maintenance data package receipt; and uploading the maintenance data package receipt into a blockchain network.
