A system for the generation of call advance data for an elevator control, which system is going to be installed in an elevator car moving in an elevator shaft and includes at least one acceleration sensor outputting current acceleration data and/or magnetometer outputting a magnetic flux signal which includes current magnetic flux data at the current position of the elevator car, which acceleration sensor and/or magnetometer is mounted in connection with the elevator car; a velocity calculating unit which calculates from the current acceleration/magnetic flux data current car velocity data; a position calculating unit which calculates from the current acceleration/magnetic flux data and/or from the current car velocity data current car position data; and a call advance processing unit which calculates from the current car velocity data and the current car position data call advance data which designates the time until which the car is able to stop at the next approaching floor in travelling direction, which call advance data is transmitted to a call allocation unit of an elevator control. Call advance data is provided in an easy manner without using existing car position detection devices of an existing elevator to be modernized.

System for the generation of call advance data

A data communication arrangement for elevators is disclosed. In the arrangement a directional antenna is used for transmitting data from elevator car. Correspondingly, the counterpart antenna in the end of the elevator shaft is transmitting with a directional antenna. In the elevator a further omnidirectional antenna is used to communicate with the terminal devices belonging to passengers. The properties of antennas may be adjusted based on the speed and location of the elevator car. In addition to the properties of antennas also other transmission characteristics may be adjusted based on the same information.

Wireless communication in an elevator

The present invention discloses a method and an elevator system, in which a passenger gives elevator calls with a personal terminal device. An elevator car is allocated to the passenger on the basis of an elevator call, the maximum time from the moment of giving the call to the moment the doors of the allocated elevator car will close on the call-giving floor is calculated. The aforementioned maximum time is sent to the terminal device of the passenger for being presented to the passenger on the terminal device.

Elevator system configured to estimate a time associated with closing doors of an allocated elevator and method of performing same

The invention concerns the automatically detection and analysis of jerks arising when an elevator car starts its ride carrying out a determination of an elevator run sequence by an elevator controller, measuring an elevator car movement with a sensor at a predetermined phase of the elevator run sequence, and determining an elevator car sway from the sensor data, further comparing the determination result with a pre-set criteria, and being followed by outputting the comparison result.

Method of eliminating a jerk arising by accelerating an elevator car

The invention relates to a method and apparatus. In the method a determining a first position of a user of a mobile node is determined at a first time instant. A second position of the user of the mobile node is determined at a second time instant. A time difference is determined between the first time instant and the second time instant. A walking speed of the user is determined using the time difference, the first position and the second position. A third position of the user of the mobile node is determined. A walking time required for the user to reach at least one elevator is determined from the third position based on the walking speed of the user. An elevator call and the walking time are transmitted to an elevator call control node.

Elevator call allocation and transmission based on a determination of walker speed

The invention relates to a method and apparatus. In the method a target area is divided to a plurality of cells. A plurality of movement paths of mobile nodes are determined, each movement path comprising an origin cell and a target cell, the origin cell and the target cell being determined using a magnetic map of the target area. The durations of the plurality of movement paths are determined for an elevator user. A route topology data structure is formed using the plurality of movement paths and the durations of the plurality of movement paths, the data structure comprising for a plurality of cells an estimated time to reach an elevator location. An elevator call in a request cell is determined by a requesting mobile node. The time to reach the elevator location is determined using the data structure and information on the request cell, and an elevator car is selected to serve the elevator call based on the time to reach the elevator location, current positions of at least two elevator cars, and current directions of at the least two elevator cars.

The invention relates to a transportation system in an environment comprising several people conveyors as well as a navigation system installed on mobile devices held by the passengers of the transportation system, which transportation system comprises at least one wireless transmission device in connection with at least one of the passenger conveyors, wherein the navigation system comprises a calibration routine for generating a reference position of the mobile device in the environment, and the calibration routine can be initiated, if the distance of the mobile device to the wireless transmission device goes below a threshold value, in which calibration routine the wireless transmission device transfers position and/or identification data to the mobile device, whereupon the navigation system on the mobile device adopts the reference position of the related passenger conveyor.
