Claim:
1. A system for remote maintenance of user units comprising: a management server; and a plurality of user units connected to the management server via a communication network, each user unit being configured for transmitting to the management server, via the communication network, state data related to hardware and software parameters associated to an operation mode of the user unit; wherein each user unit comprises: wherein the management server is configured to receive and analyze the state data transmitted by each user unit, to determine relations between the state data from a statistic correlation coefficient between a series x of values of a state of each user unit and a series v of values of another state of each user unit, the statistic correlation coefficient having a value near the extreme values of +1 or −1indicating states involved in a failure, and to transmit to each user unit a setup file comprising at least a list of states to be monitored and collected and a list of state value transitions for activating transmission of state data by the state data collecting and transmission module of each user unit.
