Jing Zhang · Gong-kuang zidonghua · 2011
For the problem that existing time synchronization algorithms of WSN are not suitable for time synchronization of data acquisition,the paper proposed a new delay time broadcast synchronization algorithm taking vibration data acquisition of motor of equipment spot inspection system of a coal preparation plant based on WSN as an example.It analyzed principle,realizing process in single-hop WSN and calculations of delay-time compensation and error of the algorithm in details,and compared the algorithm with other time synchronization algorithms of WSN with a conclusion that the algorithm has little overhead,low energy consumption and high synchronization precision.The effectiveness of the algorithm has been verified in data acquisition of equipment spot inspection system of a coal preparation plant based on WSN.
