基于过程性知识的电气工作票专家系统

Procedural-knowledge-based expert system for transmission and distribution networks electrical-work-order

针对手写工作票和以往工作票系统存在的推理性不足及实用性、通用性存在的问题 ,研究开发了一种基于B/S的自组开放式电气工作票专家系统。系统涉及的工作票种类有 :变电工作票、电力线路工作票及调度停电作业会签票。系统采用过程性知识描述和动态框架等结构方案 ,使软件系统与电气系统的接线方式及电气设备种类无关 ,开放的自组平台具有很强的适应性 ;使用复合自动推理机制生成操作项 ;使用基于有限自动机的软件工作流开发模型 ;使用流程管理解决了工作票工作流程管理中设备主管单位与人员主管单位不一致所带来的问题。

An open and self-forming expert system based on B/S was presented. The system involves several work-order-sheets, such as substation work-order-sheets, power line work-order-sheets and power-failure work-order-sheets. It can be used in transmission and distribution electrical maintenance and dispatching management system. By using procedural describing knowledge and dynamic frame, the expert system with strong adaptability is independent of system connection and equipment. A complex inference engine for generating operation-item and a developing model for software workflow based finite automaton were used in the system. This workflow management system solved some problems that engineers might meet in electrical maintenance.
