Abstract: This paper presents a way of software integration of VXI measure-control system. The VXI system includes four kinds of VXI modules ： timing-trigger module, high speed DAQ，velocity-measuring module, and switch module. It works well under cases with ETCG propellants is characterized with many working parameters, complex working-flow and adverse conditions. It can also fulfill the SPGjS measure tasks. Two system-triggering models are described： the joint action model and the separate action model. The joint action model triggers all oi the V XI modules according to a set timing sequence needed in a single task. The two forms of system triggering enlarge the VXI measure-controi system’s functions.
