Key Technology Research For Networking Automatic Test System

The development of automatic test system is full of energy. Many new ideas and technology are drawn into the system and bottlenecks are broken. By the rising of internet, network is applied to automatic test system too. Networking automatic test system, not only breaks the limitation of geographical location, but also introduces new work model to automatic test. The idea of "software as a service" will bring automatic test system into new era of "cloud computing"ABBET has been proposed a long time ago, but its openness and flexibility allowing it to take in new technology. New method of analysis and design are applied to ABBET framework to make ABBET more adaptable to new needs.In this paper, many new ideas and technology of ABBET, Object-Oriented Design and Unified Modeling are integrated together to solve the problems of automatic test system. A framework is constructed which has some characters such as short development cycle, easy to expand, easy to supplement and operation more efficiency, etc.In this paper, a new conception "class of test method" and an engine of test script are putted forward. Test methods are designed explicitly for test script running.In the new framework, a new model of test executing and a test script syntax based on XML are putted forward. With these, the new automatic test system meets the needs of testing not only now but also in the future. The system maintenance cost is reduced because that the change of system function can be realized by modify of test scripts in text editor.A new solution for saving huge amounts of data in high-speed is putted forward. A real time automatic test system can get data correctly in high sampling rate.A new technology is used in GUI for data showing in web page. It is very useful for web cross-platform browser. With this technology, the data pattern can be displayed in any kind of web browser without loss.Three automatic test systeml applications are developed. New ideas and technology are carried on in these applications, such as "an automatic test system for low-dimensional quantum structure of the sensor detection" which is supported by973#program," An automatic test system for electrical aging performance of auto parts" and "an automatic test system for leaky cable".In this paper, the latest technology is applied to automatic test system. The system framework not only adapts to the current complex charge, but also is helpful for translating automatic test system to automatic test service in "cloud computing" direction.
