面向开放式测试环境的诊断服务系统

Diagnostic System of the Open Test Environment

为了将诊断与测试分离,提高TPS与诊断推理机制的复用性,采用组件技术构建面向开放式测试环境的诊断服务系统,并详细阐述了诊断模型描述方法和诊断推理服务组件的实现技术。以XML作为诊断模型描述语言,通过数据访问接口进行诊断模型数据与知识的交互,在模型管理服务的基础上,进行高级的推理和控制服务。

To enhance the reusability of the TPS and diagnostics method of the ATS, a way to decouple the diagnosis from the test is needed. This paper proposes a method that builds an open ATS fault diagnosis system based on COM technology to resolve this problem, and expatiates two key technologies for system realization, namely diagnosis model description method and diagnosis service realization means. To facilitate the diagnosis data exchange, a diagnosis model is described in XML. Model management service component communicates with diagnosis model data through data acquisition interface. Diagnosis inference service component provides advanced inference and control service.
