High Precision Synchronous Trigger be Researched Based on WSN

Abstract:

The traditional synchronous trigger of blasting shock wave field is lineate. Because distributed range of testing field is very wide, the cost is high, disposing line is very inconvenient, reliability of testing system is at a discount. Now a more power node acts as synchronization trigger which starts up all sensor nodes isochronously by broadcast. The author named a synchronization technology as priority sequence. Single broadcast synchronization precision measuring experiment is made by the same testing method as Elson. The new experiment result is the error accord expectation , standard deviation normal school. The standard deviation is 6.8 of Elsons. The precision is exceed demand of shock wave field testing.
