Torpedo Thermal Power Plant Test System Based On Virtual Instrument Technology Development

This paper is on the basis of explaining in detail to virtual instrument technology introduce virtual instrument technology to thermal power torpedo equipment test system of our country. Structure taking PXI bus technology as the core torpedo three group yuans of propellant thermal power equipment test system synthetically, promotes the technological content to test system by a wide margin.This paper carries on careful analysis, classification and summarize to torpedo three group yuans of propellant thermal structure model, test parameters of power equipment at first, put forward different method of testing to different test parameters, choose the corresponding test hardware. Especially direct against the parameter measurement of the flow, it puts forward the new opinion at the sensor choosing and the method with digital signal for central software processing. Regard labview as the software developing platform finally, it is comparatively complete to develop the function, the interface but also has test software of databases and basic network function friendlily.In order to expand the test means, faces the computer outside interface scheme that be fast developing now, this paper proposes developing the goal based on test hardware of USB bus technology. Design through the corresponding software and hardware, developing as the core of controlling of regarding one-chip computer, regard USB1.1 norm as the test hardware of the interface agreement, realizes the design object basically.The achievement of paper to thermal power torpedo equipment test system setting up and rising the research of thermal power torpedo have certain reference value.
