Abstract:
A method for diagnosis and/or maintenance of a transportation system that has a transportation device and a remote monitoring unit, the transportation device having a control board for controlling and/or monitoring a function of said transportation device, and a local control unit for controlling said and/or monitoring said control board, may include detecting raw data associated with the function at the control board and/or the local control unit; generating condition information and/or performance information based on the raw data and calculating statistics information based on the generated information at the local control unit; buffering the generated information and/or statistics information at the local control unit; transmitting the buffered information to the remote monitoring unit; processing the transmitted information to determine a service need condition; and selectively transmitting maintenance information associated with the service need condition to the local control unit and/or a mobile service unit.

Abstract:
An elevator has a safety controller to which several safety switch arrangements are connected. The safety controller is configured to cause the stop of the elevator motor and the activation of the motor brakes. A comparator is provided in the safety controller for the determination of the status of the safety chain. The comparator is connected with a memory for storing at least one resistor reference value, which comparator is configured to output a safety chain status signal in dependence of comparison of a measured resistance value with the resistor reference value. Each of said safety switch arrangements includes at least one first resistor and a safety switch which are connected in series. The value of the first resistor is different in at least some safety switch arrangements, preferably in all safety switch arrangements. Each safety switch arrangement includes at least a second resistor connected in parallel with the safety switch, which second resistor has a higher value than the first resistor. The detection of a short circuit as well as of the opening of a safety switch arrangement are allowed.
Abstract:
A method for deploying a controller to an elevator system includes generating a request to at least one other controller for obtaining at least one parameter relating to a deployment of the controller to the elevator system, receiving a response, and in response to detection that the at least one parameter in the response comprises a set of operational parameters, initiating a configuration procedure, and in response to detection that the at least one parameter in the response does not comprise the set of operational parameters, deriving an identifier of the elevator system included as the at least one parameter in the response and generating a request including the identifier of the elevator system for obtaining the set of operational parameters. An elevator system is configured to perform the method.
Abstract:
In an elevator, the status information of the receivers, and possibly also of the transmitters, of a light curtain of the elevator is transmitted from the control unit of the light curtain as a response to a query or as messages. The control system of the elevator car is configured to receive the responses or status information and to analyze i) the status information contained therein of at least one receiver the status information contained therein of at least one receiver and of at least one transmitter relating to it, for changing or adjusting the operating mode of the elevator or for giving a control command to the operating system of the elevator.
Abstract:
The invention relates to a remote monitoring system for an elevator system. The remote monitoring system comprises at least one remotely operable intermediate device and a monitoring unit for remotely controlling operation of the at least one intermediate device at least partly. The monitoring unit is configured to: control at least one intermediate device to generate a remote com-mand for controlling at least one operation of the elevator system, and monitor a response of the elevator system to the remote command. The invention relates also to a method for remotely monitoring an elevator system.
Abstract:
The invention relates to an elevator system for observing a misoperation. The elevator system comprises an observation unit and a processing unit. The observation unit is configured to obtain data representing movement of an elevator car during a predetermined time interval and transmit the obtained data to the processing unit. The processing unit is configured to receive and store the data representing the movement of the elevator car, generate at least one statistical parameter from the received data, compare the at least one generated statistical parameter to at least one previously stored statistical parameter of the corresponding time interval, and generate a signal indicating a misoperation in response to a detection that the at least one generated statistical parameter deviates from the corresponding previously stored statistical parameter over a predetermined limit. The invention also relates to a method for observing a misoperation.
Abstract:
There are provided measures for performing a configuration control in relation to an elevator, an escalator and automatic doors in a remote manner. Such measures exemplarily comprise determining a status of a component of said control apparatus, detecting whether a change with respect to said component has occurred based on said status, defining configuration parameters for said component, if it is detected that said change has occurred, and initiating transmission of said configuration parameters to said control apparatus.
Abstract:
The invention concerns a method and a software program for determining the position of an elevator car moved in an elevator shaft, wherein an acceleration is measured and combined with measured open/closed states of the car door. The open-states of the door are used to identify floor-levels and a moving run sequence, wherein the car position estimate is then compared with allocated floor-levels from which the destination floor-level is calculated to extract the exact position of the car within the elevator shaft.
