BOM技术在复杂电路虚拟维修系统中的应用

给出了电路虚拟维修的定义，在复杂电路虚拟维修系统结构的基础上提出了建模需求，并给出了计算模型和交互模型的定义。以形式化的方法定义了BOM（Base Object Model）概念模型，通过分析电路仿真的特点，确定了电路BOM概念模型中的实体类型、事件类型和交互模式；特别是采用了“将实体类型区分电子元件类型和电信号类型，分别以客观属性和仿真语言描述的方法进行定义”的原则，既满足了仿真效果，又简化了建模复杂性。通过建立某型装备的复杂电路虚拟维修训练系统，验证了基于BOM的交互模型的有效性和实用性。

Application of BOM in Complex Circuit Virtual Maintenance Systems

In this paper, circuit virtual maintenance is defined. The modeling requirements are proposed based on the complicated circuit virtual maintenance system, and the concepts of computing model and interoperable model are introduced. The formalized definition of BOM （Base Object Model） conceptual model is proposed, and the elements identified as entity type, event type, and pattern of interplay in circuit BOM are researched based on the characteristics of circuit simulation. Especially, the entity types are used to distinguish from electrics component type and signal type, and they are consequently described by its attributes and circuit simulation language separately, which satisfies simulation requirement and simplifies the modeling complexity. By building the complex circuit virtual maintenance system of certain equipment, the validity and practicability of interplay model based on BOM are validated.
