摘要

with the development of high technologies, the structure and capability of ATS has been greatly improved, such as footprint, compatibility, and cost and test efficiency. However, the survival ability of ATS is always slighted by researchers. In order to improve the survival ability of ATS, adopting the idea of autonomous decentralized systems, this paper designs the Autonomous Decentralized Test System (ADTS), which is aiming at enhancing ATS's survival probability and online maintainability. The new requirements of online specialties for ADTS are advised including online expansibility, online fault-tolerance and online maintenance. Firstly, with the consideration of requirements thoroughly, a model called double circle Autonomous Decentralized Test System was put forward, which is analyzed form three aspects: functional analysis, online characteristics analysis and autonomous ability analysis. After a demonstration, the model is proved that it has autonomous controllability, autonomous correspondences and invulnerability in structure. Secondly, ADTS test information standardization methods were studied. An approach that using automatic markup language technology to solve ATSs' test information standardization problems was promoted. Thirdly, ADTS's semantic characteristics is analyzed, then divided its data type into notification data and control data; the autonomous decentralized test protocol based on quality of service is brought forward then undergo a process of performance assessment. Fourthly, ADTS resource configure optimum method is put forward, the concept named "common test core" is invented, and the method for consisting Autonomous Decentralized Test System based on common test core was given. ADTS extends its value; which can improve ATS's survivorship and maintainability. The method is also useful for solving test information standardization and ATS compatible problems.
