Disclosed is an elevator system for a multi-level architectural structure, the elevator system having an elevator controller for an elevator in a hoistway, wherein the elevator controller effects a first determination of whether passengers or goods are in the elevator and effects a power mode for the elevator based on the first determination.

The present invention provides an elevator encoder diagnostic system and an elevator encoder diagnostic method by which input and output ports are kept from being occupied, functional restriction is suppressed, and abnormalities and malfunctions occurring in encoders provided in a dual-system can be detected. The elevator encoder diagnostic system according to the present invention includes a first encoder 16a and a second encoder 16b that are provided on a rotary portion of the elevator, a first diagnostic unit 21a connected to the first encoder, and a second diagnostic unit 21b connected to the second encoder, a first determination unit 23a and a second determination unit 23b that detect differences between encoder rotation amounts of the respective encoder systems and rotation detection signals of the other encoder systems, and, if a difference therebetween exceeds a predetermined threshold, determines that an abnormality has occurred.

A brake device includes: a fixed member; a moving member which is movable between a retracted position in which the moving member is adjacent to the fixed member and separate from a braking member, and a braking position in which a friction plate of the moving member contacts the braking member and provides a braking force to the braking member; an elastic member connected between the moving member and the fixed member; a coil disposed in the fixed member; and a controller which provides an operating current to the coil when the elevator is in normal operation, wherein the controller is configured to implement a test mode in which the controller provides a test current less than the operating current to the coil and determines whether the moving member has been attracted to the retracted position.

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.

A mobile control unit and a method remotely control an elevator installation in an inspection mode, wherein the elevator installation includes an elevator car, an elevator controller and a safety circuit. The elevator controller automatically controls the elevator car for movement in a normal mode of the elevator installation when the safety circuit is electrically closed. In order to control the elevator installation, the mobile control unit is connected to the elevator installation such that the mobile control unit can switch the elevator installation between the normal mode and the inspection mode, and the elevator car can be manually controlled for movement via the mobile control unit in the inspection mode of the elevator installation.

A method and a system for the evacuation of buildings providing an elevator system includes at least one elevator car and an elevator shaft. The system includes a device to detect an incident or a device to receive an emergency signal in this regard, a device for determining the floor of this incident, and at least one sealing element (positioned in the elevator shaft and constructed to seal the elevator shaft, so that the elevator shaft is divided in at least two sections.

An elevator preventive maintenance system capable of helping, when an abnormality of an elevator is predicted to occur, a concerned person needing no countermeasure information to grasp information quickly and easily, and helping a concerned person needing countermeasure information to react to the abnormality quickly and precisely. The system includes: a prediction section configured to predict an abnormality of an elevator to occur, based on abnormality prediction information; a storage section configured to pre-store concerned person information relating to the elevator; a communication section configured to transmit abnormality occurrence prediction information to concerned person in the case the abnormality is predicted to occur.

The present invention relates to maintenance of a passenger transport system. An apparatus for maintaining a passenger transport system according to the present invention includes a wireless beacon and a personal mobile terminal. The wireless beacon is mounted substantially at a registration entrance for entering the passenger transport system to perform a maintenance operation and configured to broadcast a wireless signal to the surrounding area. The personal mobile terminal is carried by the maintenance operator and configured to sense the wireless signal when the maintenance operator approaches the wireless beacon. At least one of the wireless beacon and the personal mobile terminal is configured to automatically generate and send, based on successful sensing of the wireless signal by the personal mobile terminal, maintenance register information indicating that the corresponding maintenance operator has checked into a maintenance operation process. The present invention can significantly simplify the check-in operation.
