The Application Of Virtual Instrument Technology In The Design Of The Complex Characters Testing Instrument Of Uderwater Sonic Detector

With the continuous development of modem science technology and economy, various measure and test instruments are required to accomplish more and more complicated jobs in measuring, monitoring and automatic manufacturing. And the demand for measure technology and test equipment is getting higher. As a result, the testing cost increases by a wide margin. In recent years, a new measure technology that combines the technologies of electronic measure, computer and web ?virtual instrument technology, provides effective ways for designing instrument which has multifunetion, high efficiency and ability rate of cost. Research of he design of the Complex Characters Testing Instrument of Underwater Sonic Detector?uses the virtual instrument development platform LabVIEW as main tool. With the design way of virtual instrument, the development of the instrument has been accomplished basically. This instrument is able to test the sensitivity, resistance and capacitance of several underwater sonic detectors automatically. Testing results can be shown and printed out with different ways, at the same time the results can be saved and inquired. The instrument also possesses the function of long-distance safeguarding. During the development of the instrument, the writer also .designed a piece of signal condition board specifically. Its performance reaches designing demand and meets the need of the system. The whole instrument system is satisfied for engineering project with fine stability, accuracy and ability rate of cost.
