【Abstract】 Shorter developing period,lower cost and higher quality are as the requirements of current competition for testing systems. Based on virtual instruments and multi-sensor data fusion theory, an intelligent diagnosis system using agile virtual testing technique is presented.The paper discusses the features, advantages, composition of agile virtual test and also the scheme, contents, key techniques of its design. Software widget is using for building virtual instruments which helps the users to build their special testing systems with unprecedented convenience and flexibility and to improves the software reusability. The fusion center includes variable fusion diagnosis methods, such as neural network and genetic algorithm, fuzzy theory, probability?Applying agile virtual test technique, the topological structure of diagnosis system will be come more open and flexible. The software strategy will be as the developing trend of PC-based automation testing technologies.更多还原
