10. The data carrier of claim 9 , wherein the computer is a distributed computing system part of a cloud computing system.

11. A method for diagnosis and/or maintenance of a transportation system, said transportation system including a transportation device and a remote monitoring device, the remote monitoring device remote from the transportation device, the transportation device including a control board, and a local control device, the transportation device including an elevator that includes a plurality of doors at separate, respective floors of a plurality of floors, the control board configured to control and/or monitor a function of said transportation device, the local control device configured to control and/or monitor the control board, the method comprising:

detecting raw data at the control board and/or the local control device, the raw data associated with the function;

generating condition information and performance information based on the raw data at the control board and/or the local control device;

calculating statistics information based on the condition information and/or performance information at the local control device, wherein the statistics information is calculated separately for each door on each floor of the transportation device;

buffering the condition information, performance information, and statistics information at the local control device, wherein the performance information is buffered separately for each door on each floor of the transportation device, wherein the statistics information is buffered separately for each door on each floor of the transportation device;

transmitting, at the local control device, the buffered performance information and/or statistics information to the remote monitoring device, in response to a determination at the local control device of an elapse of a particular time interval;

processing the transmitted performance information and/or statistics information at said remote monitoring device in response to receiving the transmitted performance information and/or statistics information to determine a service need condition associated with the transportation system, including determining at said remote monitoring device that a maintenance action is needed to perform maintenance on the transportation device; and

selectively transmitting maintenance information associated with the service need condition to the local control device and/or a mobile service device in response to the determining the service need condition, including the determining at said remote monitoring device that the maintenance action is needed to perform maintenance on the transportation device.

12. The method of claim 11 , further comprising:

managing a database at the local control device, the database storing data associated with the condition information and/or performance information.
