Virtual Test System Design And Implementation Of Optical-electric Transducer

Traditional instrument test need specify equipment, which not only expensive, but also difficult to maintenance, and need people to process data manually, so it makes the test precision lower, people have to do lots of work after the measurement, it can't meet the really requirement. With the development of computer technology, testing technology has made tremendous progress. Testing System research based on the Virtual Instrument appears to be particularly popular.The rapid development of China's power industry makes the demand for electricity transducer increasingly fast. Because the traditional transformer can not meet the increasingly high voltage, Current site environment's requirement, the superior performance of optical-electric transducer is becoming a substitute for traditional transducer. In order to ensure long-term stable operation of the optical-electric transducer, the test for optical-electric transducer has become an important part.Because of this, we designed optical-electric transducer test system based on the virtual instrument, mainly do research in the following areas:(1)Base on analysis optical-electric transducer's operation principle, basic character, basic apply and output signal's character, simulated the optical-electric transducer by LabVIEW .(2)Base on system analysis of domestic and foreign's virtual instrument technology, and the latest research results. Established optical-electric transducer test system's test target, completed the test system's structure design.(3)Use multi-function, modular design method, designed the test system's software include data acquisition, data analysis, data access and data output modules by LabVIEW.(4)Designed simulation experiment to test the performance of the test system, analysis of the simulation results and test standards for comparison, meanwhile, the same type test's simulation results do comparison too, in order to verify the designed virtual instrument's software and hardware functions.(5)Based on researching the results of the simulation test, do error analysis for the system.
