A drone sensor system detects an environment and/or a state of flight, an actuator system controls the drone, and a control device controls the actuator system. Method steps include: control device receiving sensor data generated by sensor system; determining actual distances of drone relative to first and second shaft walls from sensor data; and generating control signal actuating actuator system such that drone flies based on deviation of actual distances from target distances and a target flight route to a target position. An actual flight route is determined from the sensor data, and the control signal is generated based on a deviation of the actual flight route from the target flight route. Door regions and/or height markings in the shaft are recognized from the sensor data to determine the actual flight route.

Abstract: An elevator safety supervising entity (SSE) includes a car safety supervising unit (SSU) controlling functions of car safety components and having at least one car sensor sensing car-related parameters, a head SSU controlling functions of shaft safety components and having at least one shaft sensor sensing shaft-related parameters, and a data linkage transmitting signal data between the SSUs. Both SSUs detect a failure in the other one of the SSUs and in the data linkage signal data transmission and in response switch from a normal operation mode to a failure operation mode. In the failure operation mode, the SSUs operate autonomously to keep the elevator operative at least temporarily with a sufficiently high safety even when functions of the elevator SSE are disturbed due to failures and e.g. passengers may be evacuated from the elevator car before completely stopping elevator operation.

Abstract: A method determines information relating to elevator components received in an elevator shaft, the elevator components each being provided with a machine-readable marker on which component-specific information is stored, which information is read out by a marker reading device. In the method, a movable elevator element on which the marker reading device is arranged is moved through the elevator shaft and the component-specific information is read out from the markers. The markers can be, for example, markers that can be read out electromagnetically and in a contactless manner, such as RFID tags. The method also includes a comparison of the read-out component-specific information with nominal specifications, and the compiling of a report indicating instances of conformity and/or differences between the read-out component-specific information and the nominal specifications.
