Equipment Fault Prediction via System on Chip

摘要

Fault prediction is a core problem for predictive maintenance. Predictive maintenance is a new branch in maintenance research field, and it can cut dawn a large number expenses that cost in prevent maintenance, and reduce the time of stop machines. The key problem of fault prediction is to acquire state data of the equipment continuously, build the system state reliability models according to the state data, and to determine the equipment whether failure or not in next time via the models. System on chip(SOC) is a small system and its cost is lower than normal test system. So it is suited for a BIT system for fault prediction. In this paper, the construction of SOC is discussed; fault prediction method and the key problems are described in detai.
