Abstract:

Sensor network is deployed to monitor equipment operations and issue alarms when potential malfunctioning is detected. Once the sensor network triggers the alarms of the most severe category, immediate interruption of equipment operations is required, which costs significantly to the network velocity. Unlike the existing work, we do not aim to improve the accuracy of the current alarm rules that operators deploy. Instead, we provide prediction of those alarms in the most severe category several days in advance so that operators have sufficient time to respond. There are three concerns we bear in mind when developing prediction model. The first is to keep false alarm rate very low due to the operation resource constraints. The second is to develop big data techniques to analyze large volume of sensor data around 2TB collected in half a year. The last is to provide human interpretable rules to facilitate decision process by operations group. This work provides solutions to address these issues.
