4 Current State of Research
As already mentioned within this diploma thesis, there seems to be no research
activity within this particular setting of sensor based temperature monitoring of
cooling devices at the moment. That is why the described approach from section 2.3
still seems to be state of the art.
Hence this chapter will focus on similar fields of activity. The setting of machinery
condition monitoring and the setting of measurement data analysis seem to be
promising. Therefore, current research activities within these fields will be introduced
and tested on applicability.
4.1 Current State within the Setting of Sensor Based Temperature
Monitoring
The only found article, describing exactly this setting was written by H. Bonekamp in
1997 and called “Monitor to guard fridge temperature”. This article points out the
importance of temperature monitoring of fridges, even at home. Especially gone off
food, due to too high temperatures within the fridge could be avoided by the use of
temperature monitoring. Bonekamp suggests and describes the installation of a small
sensor based temperature monitoring device. It only consists of three LEDs to
indicate a low, a correct or a high current temperature. [Bonekamp97]
As this approach is also based on the idea of just setting critical temperature limits to
classify the current condition of a cooling device, other approaches have to be found.
Therefore, the following subsections will introduce briefly common approaches and
current state of research from the related settings of machinery condition monitoring
and measurement data analysis.
4.2 Current State within the Setting of Machinery Condition
Monitoring
Condition monitoring of industrial machinery is done for many different reasons.
Common ones are ([Kolerus95], p. 3):
• To avoid damage to machinery, employees or the environment
• To avoid unexpected breakdowns of machinery
• To do condition based maintenance
• Quality control
