IEEE 1588-Based Synchronization System for a Displacement Sensor Network
TLDR
This paper deals with a displacement sensor network that is built over Ethernet and synchronized according to IEEE 1588, and attention is focused on the IEEE1588 implementation.Abstract:
Distribution of precise time reference in an Ethernet network allows the implementation of distributed measurement systems, overcoming the limitations of a complex architecture. This paper deals with a displacement sensor network that is built over Ethernet and synchronized according to IEEE 1588. Measurement devices share the same time reference, enabling accurate calculation of cross-derived quantities (multidimensional speed and acceleration). In this paper, a description of the sensor architecture is given, and attention is focused on the IEEE 1588 implementation. In particular, the proposed low-cost system does not use any dedicated synchronization hardware, but it can reduce the deviation from time reference down to 20 .read more
