Method for diagnosis and/or maintenance of a transportation system, and software program

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 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/or 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;
• buffering the condition information, performance information, and/or statistics information at the local control device;
• transmitting, at the local control device, the buffered condition information, 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 condition information, performance information, and/or statistics information at said remote monitoring device in response to receiving the transmitted condition information, 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.
