| 自动测试系统ATS通用化是测试与诊断技术的重要发展方向，直接决定了系统的设计维护成本、技术寿命和测试诊断性能。现有的通用ATS主要采用集中式系统架构，系统维护成本和难度较高，信息互通性和通用化程度不理想。针对集中式ATS架构的局限性，设计并验证了一种基于自动测试标记语言ATML标准集、以网络为中心的分布式通用ATS架构。经验证演示实验，该架构较好地解决了仪器和系统的互换性问题，并通过发掘仪器的智能性，缓解了网络的延时问题和带宽压力，对构建通用ATS具有重要工程意义。 |

| Abstract: |
| The generality of an Automatic Test System(ATS) is an important development direction of testing and diagnosis technologies, which determines the design and maintenance cost, technical life, and test diagnosis performance of the system directly. The existing general ATS mainly adopts centralized system architecture, which leads to high cost and difficult system maintenance. Besides, the information interoperability and generalization of such architecture are not satisfactory.According to at the shortages of the centralized architecture of ATS, this paper designs and verifies a distributed ATS architecture based on the Automatic Test Markup Language standard and the network. The simulation results demonstrate that the distributed architecture can not only solve the interchangeability of instruments and systems much better, but also alleviate the problem of network delay and bandwidth pressure by exploring the intelligence of instruments. Both the analysis and simulation results show that the distributed architecture based on ATML has important engineering meaning for building a general ATS. |
