The at least one first sensor assemblies and the at least one second sensor assemblies form a contactless position sensing system for determining a position of the elevator car within the elevator shaft.

Methods and systems for determining elevator car locations are provided. Aspects includes operating, by a processor, a machine room sensor to collect vibration data associated with one or more components in a machine room of an elevator system, wherein the elevator system comprises an elevator car and a hoistway and analyzing the vibration data to determine a position of the elevator car in the 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 movement of the tie down mechanism in at least one direction. At least one detector detects movement of the tie down mechanism along the direction and provides an output indicating at least one characteristic of the detected movement.

An elevator system includes a hoistway (217) including a landing (225A-225C), which includes a landing door (227A-227C), an elevator car (203), comprising an elevator car door (229), arranged to move within the hoistway (217), a first safety switch (231; 233) configured to indicate a potential hazard in the elevator system (201) and a controller (215). The controller (215) is configured, when the first safety switch (231; 233) is triggered, to stop movement of the elevator car (203) and determine whether the elevator car (203) is located anywhere within an unlocking zone (253) in the hoistway. The controller is further configured, if it is determined that the elevator car (203) is located anywhere in the unlocking zone (253), to allow the elevator car door (229) and landing door (227A-227C) to be opened.

Disclosed is an elevator system in a building, the elevator system including a first elevator car for transporting a passenger between a plurality of building levels, the system including a controller that controls the elevator car, the controller: rendering a first determination that the passenger has requested elevator service from the first lobby, rendering a second determination to assign the elevator car to provide service to the passenger at a first lobby for the first level, effecting a first transmission to the elevator car to effect the second determination, rendering a third determination that the first lobby becomes unoccupied in a time period between effecting the first transmission and the elevator arriving at the first lobby for servicing the first passenger, rendering a fourth determination to release the elevator car from effecting the second determination, and effecting a second transmission to the elevator car to effect the fourth determination.

There is provided a diagnostic device for vertical transportation devices, which can obtain information for appropriately diagnosing a vertical transportation device. The diagnostic device for vertical transportation devices includes a housing-unit that defines an outer profile, a storage-unit that is housed in the housing-unit and stores information, an acceleration-detection-unit that is housed in the housing-unit and detects, with the housing-unit attached to a moving object in the vertical transportation device, acceleration in a vertical direction and acceleration in a horizontal direction of the moving object as diagnostic information of the moving object in the vertical transportation device when the moving object has moved, and a control-unit that is housed in the housing-unit and causes the storage-unit to store information about the acceleration in the vertical direction and information about the acceleration in the horizontal direction, which have been detected by the acceleration-detection-unit, in association with information about a detection timing.

The present invention relates to determining the movement of a passenger relative to an elevator landing area, which belongs to the field of elevator intelligent control technologies. An automatic elevator calling system of the present invention comprises: a first wireless signal module installed in an elevator car, which is used for broadcasting a first wireless signal; wherein the first wireless signal module is further used for receiving information regarding the movement of a passenger relative to the elevator car, and the information regarding the movement is determined based on the change in a signal strength of the first wireless signal received by a personal mobile terminal carried by the passenger.

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 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.

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.
