ELEVATOR SYSTEM AND METHOD FOR MONITORING AN ELEVATOR SYSTEM

An elevator system (34) comprises a plurality of elevators (1) each of the elevators (1) comprising: a diagnostic unit (17) which is configured for running at least one diagnostic routine checking components of the elevator (1) and providing elevator operation and diagnosis data; a communication unit (30), which is configured for transmitting the elevator operation and diagnosis data provided by the diagnostic unit (17) to a remote diagnostic system (40); and for receiving control commands from said remote diagnostic system (40); and a control unit (14), which is configured for executing the control commands received by the communication unit (30). The elevator system (34) further comprises a diagnostic system (40) comprising at least one data receiving unit (42), which is configured for receiving the elevator operation and diagnosis data transmitted from the communication unit (30); at least one storage unit (44), which is configured for storing elevator operation and diagnosis data; at least one analyzing unit (46), which is configured for automatically analyzing the elevator operation and diagnosis data received by the at least one receiving unit (42) in order to detect a malfunction of an elevator (1); and at least one instruction unit (48), which is configured for sending instructions to the communication unit (30) of an elevator (1), for which a malfunction has been detected, instructing the control unit (14) of said elevator (1) to perform at least one specific action in order to overcome a detected malfunction.
