  • Publication number: 20190193986
    Abstract: A method for detecting an entry into an elevator car of an elevator system by a passenger uses a mobile device carried by the passenger. The mobile device has at least one, but in particular a plurality of sensors, with which the mobile device detects and evaluates measured values. An entry into the elevator car is then detected on the basis of comparing the measured values with at least one stored signal pattern.

  • Publication number: 20190193992
    Abstract: A method for monitoring an elevator system utilizes a mobile terminal device having at least one sensor to collect measurement values in an elevator car. The mobile terminal device is carried by a passenger of the elevator system. The collected measurement values are transmitted by the mobile terminal device to a central evaluation unit where they are evaluated. The mobile terminal device activates a measurement mode when it detects that it is located in a region of a shaft door of the elevator system.
