KEYNOTE

deliver I return to store energy under a slogan that seeks to compensate for the disturbance. The
slogan is known with the name of reference and his generation is given through the opening and
closing of power switches (usually semiconductor). As the disturbance that can be compensated,
this will depend on the strategy of control and the way that the filter is connected to the
network. Depending on the desired purpose, filter connects in series to the network, correction
of disturbance in the tension, in parallel, correction of power disturbances, or as a mixture of
both.

2.8 E-maintenance

We define e-Maintenance as a management concept of maintenance whereby assets are
controlled and managed over the Internet.
E-Maintenance as a maintenance strategy, i.e., a method of electronically using real-time data
obtained from the equipment using digital technologies (mobile devices, sensors, technology,
Internet, etc.) as a maintenance plan (i.e., a structured set of tasks with an interdisciplinary
approach that includes the monitoring, diagnosis, prognosis) may be considered (decision
and control processes), as a type of maintenance (based on CBM, proactive and predictive
maintenance) or as a maintenance support (i.e., resources and services needed to carry out
the maintenance).
E-Maintenance is an interdisciplinary approach that consists of monitoring, diagnosis, prognosis,
and control. Control consists of the evaluation in real time of the assets and the detection of
abnormal States. The diagnosis, identifies the causes of advance degradation or failure of the
equipment. The Outlook analyzes the impact of the failure on the computer and the system. As a
result, they can make decisions and carry out maintenance actions if necessary, with the aim of
reducing the number of inspections "in situ" and eliminating unnecessary maintenance activities.

E-Maintenance integrates the principles as applied in the maintenance, by adding a Web
service and principles of collaboration. Collaboration is not limited to sharing and exchanging
information, but knowledge and intelligence between different units, departments, expert
operators and companies in a collaborative environment for the development of better decisions
of maintenance throughout the lifecycle of an asset.

The e-Maintenance Management model breaks the physical distances through the creation of
intelligent networks using Internet and wireless communication technologies. Thus, a platform
e-Maintenance exists when you replace the conventional hierarchical structure by an intelligent
structure of (Intelligent Manufacturing Systems IMS). It consists of giving intelligence to components
via electronic technology. To do this, it is necessary to have support for Exchange of information
and communication networks in real time between the devices. Through a system of alarms set-
based monitoring of the conditions of the equipment, it is possible to optimize the priority of
peacekeeping activities. The influence of all of these capabilities is even more important when
the tasks are characterized by the immediacy and the high mobility of the linked staff.
These potential improvements are summarized below:

• Remote maintenance
• Cooperative maintenance

• Maintenance on-line
• Predictive maintenance
• Troubleshooting
