On-chip order tracking method using wireless sensor networks based on hardware cross-layer design

Abstract

Order-tracking technique is widely accepted to account for speed variation. Meanwhile, Wireless Sensor Networks (WSNs) is highly focused since the nodes can collect vibration data in special applications. Thus, it’s meaningful to realize order-tracking using WSNs. In this paper, a novel on-chip order tracking method using WSNs based on hardware cross-layer design is proposed, in which the vibration data can be sampled with uniform angle on chip. First, a high performance WSNs system based on dual-core architecture is developed to monitor shaft angle and machine vibration, and hardware cross-layer design is researched to send key-phase pulse with low delay jitter. Second, a data sampling control method is established to realize on-chip uniform angle sampling. Finally, the performance of the proposed on-chip order tracking method is verified by some experiments.
