Development of Lab VIEW DAQ for Static Test of Propulsion Motors used in Missiles

Pavan Koundinya, B.M. Karthik Reddy

Abstract


The „Network Integrated, Real-time, Multi signal Data Acquisition System‟ is used for performing the static tests of propulsion motors used in missiles. The test bed comprises of data acquisition stations spread over an area of one square kilometre, which are integrated by Ethernet connectivity. The interconnectivity, control of acquisition, and data transfer between individual systems is achieved using TCP /IP protocol. The physical parameters acquired in Real-time are Pressure, Thrust, Temperature, Strain, Vibration, and Acoustic Signals. With this system, we can deterministically acquire more than 300 channels of data and make them available to the control via the Ethernet. The data is recorded, acquired and viewed in real-time and data analysis is performed offline. A program is developed and used to evaluate the performance of missile. Lab view offers object oriented structure, speed, maintainability and easy debugging. automatic test equipment (ATE), synthesizing design and application, become the effective approach to improve complex system testability and maintainability. Widely, PXI (PCI extensions for Instrumentation) is applied to the domain of automated test.
