Virtual instrument breaks through the limits of traditional instrument, bining with powerful puter and corresponding hardware. The system consists of three subsystems: pressure acquisition, velocity acquisition and signal processing. In virtual pressure acquisition system, setting parameter, data acquisition, saving and printing are achieved by control of software and fulfill need of dynamic test. Furthermore, data acquisition card driver makes plug and play possible. Signal processing system consists of filter, FFT, joint time frequency and wavelet analysis. Some examples are also given. Keywords: virtual instrument, LabVIEW, data acquisition, velocity acquisition, filter, FFT, joint time frequency analyzer, wavelet transformI. Virtual Instrument Software LabVIEWFor exploring artillery internal principle and validating correctness of artillery models, everyone pursues accurate and true data, including engineers, technicians and researchers. But the artillery test system using now is unwieldy and out of time, an advanced test and analysis system of artillery basic parameter is badly needed. Our research recalls the need, and for the first time, it introduces virtual instrument technic into artillery test field.Virtual instrument LabVIEW is a graphic programming software used in fields as scientific calculation, process controlling and testing. LabVIEW has lots of function icons especially designed to deal with tasks such as acquiring data, controling instruments,analyzing signal and processing data. Furthermore, as open industry standard and general software development platform, LabVIEW provides various drivers for mon instruments.LabVIEW is powerful and it is an integrated software packages. In order to simulate the work of traditional instruments, LabVIEW provides various widgets, such as knobs, switches, meters and analog digital oscillograph. Moreover, designers can design widgets by themselves. LabVIEW can municate with CPIB, VXI, RS232, RS485and data acquisition card. It has interior program warehouse providing various ways of connection. It could connect with exterior program and software system through DDLs and ActiveX, to carry out the tasks that can’t be finished by or difficult performed by itself. After all, LabVIEW’s unitary function is amazing.II. Design of data acquisition virtual instrumentA Testing Principle of pressure signalThe testing of instantaneous pressure in our research is based on PCDAQ system. First of all, pressure in gun barrel is transformed into electric signal by pressure sensor. A charge amplifier magnifies the signal. At last, the magnified signal is transferred into puter through data acquisition card fixing in PC. DLL makes data acquisition card and LabVIEW connect together for further displaying and processing. B Hardware of data acquisition virtual instrument Hardware of data acquisition virtual instrument mainly contains two parts: First part is puter, generally one PC or workstation. It is a core of hardware platform. Second is I/O interface instruments. Its main works are signal acquisition, magnification of signal and analogdigital transformation. The selection of I/O interface instruments depends on actual needs. I/O interface instruments include data acquisition card, GPIB, VXI and serial interface. PCDAQ system is a virtual instruments system and its main hardware contains acquisition adjustmen circuit and personal puter. PCDAQ has PCI, ISAor general puter bus. Once insert data acquisition card into empty rabbet of the puter, the system is ready to work. The software LabVIEW makes instruments transport data into puter and the puter records and processes the data. Also PCDAQ test system is the cheapest in numerous virtual test systems. How to make up of a PCDAQ virtual test system? First insert data acquisition card into empty rabbet of puter (LabVIEW has all kinds of data acquisition card driver to make DAQ work properly)。 Second, A/D transducer transports digital/analog signal into puter。 Third, puter analyzes and displays the digital signal. Moreover, it can do feedback control through D/A transducer. The data acquisition system is multicenter and multiparameter structure. The main tasks of data acquisition and processing system are catching and recording signal. First, pressure signal should be transformed into electric voltage or current signal. Second, adjust signal through adjustment circuit. At last, the signal is transported into puter through data acquisition card.Interface of A/D transducer and puter are integrated in data acquisition card PIO
