Provided is an apparatus configured to detect a car position by performing threshold processing on a voltage caused by an AC magnetic response through use of an identification plate in which a slit pattern is formed and a plurality of coils, the apparatus including a circuit configuration capable of switching between a normal operation for detecting the car position based on an on/off detection operation using the plurality of coils and a self-diagnosis operation capable of verifying the on/off detection operation irrespective of the presence or absence of the identification plate with a car in a stopped state by forcedly applying a magnetic field to the coils.

A measuring tape arrangement is used in an elevator system for determining a position of an elevator car along a travel path. The measuring tape arrangement has a one-piece measuring tape arranged along the travel path, wherein varying location information is stored along the measuring tape, by which information a current position of the car relative to the measuring tape can be determined, and a retaining structure arranged at an upper end of the travel path on which structure the measuring tape is fastened by a fastening device at a fixed position relative to the travel path. A receiving device receiving a measuring tape supply is arranged on the retaining structure, wherein a measuring tape piece of the measuring tape supply can arranged along an extension portion when the travel path is extended upwards by one extension portion.

A method and an apparatus for allocating an elevator of an elevator system are described. In the solution, image data associated with an area associated with a plurality of elevators is obtained. An automated guided vehicle is detected based on the image data. Parameter data associated with the automated guided vehicle is determined based on the image data. Information indicating a destination floor for the automated guided vehicle is obtained and an elevator car is allocated for the automated guided vehicle by taking into account at least the parameter data and the destination floor. Information identifying the allocated elevator car is caused to be transmitted to the automated guided vehicle.

A device and a method for controlling an apparatus being an elevator, an escalator or automatic doors are provided, by which it is detected whether a fault is present in the apparatus, it is determined, when the fault is present, whether an automatic fault clearing may be carried out, and if it is determined that the automatic fault clearing may be carried out, the automatic fault clearing is performed by automatically clearing one or more faults.

A guide for individual movement machinery. The guide includes a base, a frame and a monitoring system. The monitoring system includes arrays of sensors affixed to each of the base and the frame to respectively sense guide conditions and to generate readings accordingly.

Systems and methods floor bypass in an elevator system are provided. Aspects includes receiving, by the first controller, a first elevator destination call to a first floor, wherein the first destination call causes a first elevator car to dispatch to the first floor. First sensor data associated with a first passenger area associated with the first elevator car is collected, from the first sensor. A presence of a passenger in the first passenger area is detected based at least in part on the first sensor data. And the first elevator car is operated based on the presence of the passenger in the first passenger area.

An elevator position reference system and a method of monitoring building settlement using such a system. The elevator position reference system includes a hoistway extending in a vertical direction. The system also includes a first position measurement tape extending vertically along a portion of the hoistway and an upper tensioning device, connected to an upper end of the first position measurement tape so as to apply a tensioning force in the upwards vertical direction. A lower end of the first position measurement tape is fixed within the hoistway. The system also includes a second position measurement tape extend vertically along at least some of said portion of the hoistway and a lower tensioning device, connected to a lower end of the second position measurement tape so as to apply a tensioning force in the downwards vertical direction.

An elevator car position detection device is provided capable of preventing erroneous detection of a metal object other than an object to be detected. The elevator car position detection device includes: an object to be detected provided in one of a hoistway and a car of an elevator, the object to be detected being formed of a magnetic body and having a slit-like opening; and a magnetic detection device provided in the other of the hoistway and the car of the elevator, the magnetic detection device being configured to detect a change in magnetic flux density according to the slit-like opening when facing the object to be detected.

Embodiments of systems and methods for digital control of elevator and other access gateways are described herein. More specifically, embodiments comprise systems and methods for retrofitting or outfitting elevator systems with digital control systems that can be universally applied to virtually every manufacturer's elevator systems.

A method and system for determining the position of an elevator car movable in a shaft of an elevator installation capture images of shaft components and/or shaft equipment serving other functions using an image capture unit on the car. A current image is compared with at least one stored comparison image of the components and/or equipment in a travel direction of the car to determine a current position of the car in the travel direction. If there is no information regarding the position of the car from a previous determination step, for example if the elevator installation is restarted, a current image is compared with all the stored comparison images. Based upon this comparison, one possible position or a plurality of possible positions of the car are determined. These possible positions are checked at least once before one of these positions is adopted as the current position of the car.
