Casestudie Breakdown prediction Contell PILOT - Transumo

a converter that is also available for XiltriX. Of course, a substation connected like
this needs an own power supply because the network does not provide energy.
The second additional possibility is the usage of a wireless LAN. Similar to the just
introduced approach, the substation is equipped with an own power supply. The only
difference is the way of sending the data to the web server. Instead of using a
converter to use the local area network, an additional wireless LAN is installed. This
method saves a lot of wiring, but it is less reliable than a cable connection, due to
existing radio interferences within hospitals. [Weerdesteyn06]
3.2 XiltriX’s Basic Functionality
The last section focused on the general idea and the technical basis of XiltriX. This
section will now introduce XiltriX’s basic functionality. This means, that these features
are mandatory for a sensor based monitoring system and nothing unique. Section 3.3
will introduce special features that were implemented to solve current limitations of
the current monitoring approach.
Figure 3-1 pictures the flow of information. A person in charge is notified in case of
exceeding the predefined temperature limits. Beside that, information can be
obtained from two additional sources as indicated by the dashed arrows:
1. A display that shows current data
2. The database that contains the historical temperature data
XiltriX offers both possibilities. Figure 3-3 pictures the main screen of XiltriX. It gives
an aggregate overview of current data of all monitored devices and can be accessed
on every computer within the network. Most important is the white table in the middle
of the screen because it contains machine based data. Depending on the system’s
configuration this table shows current data from machines of one or more
departments. The first column represents the status of an optional connected door
sensor. Empty rows indicate a missing of this sensor.
Furthermore, a unique identification number and a description are assigned to every
monitored device, which is displayed in the second and the fourth column. The third
column indicates the activation of the high resolution mode by showing an asterisk.
