IEEE 1451网络化智能传感器的通用建模方法及应用

为提高网络化智能传感器的互操作性,在分析IEEE 1451标准传感器的定义和功能需求的基础上,利用统一建模语言(UML),分别从静态用例建模、动态顺序描述和系统部署3个层面构建了一系列面向网络化测控的通用型智能传感器系统模型,搭建了一款可用于在线检测绝缘子污秽状况的网络化智能传感器。相对于从传感器原型开始开发,该方法减少了60%以上的开发时间。实验结果表明,利用UML统一建模方法可以有效描述基于IEEE 1451标准的网络化智能传感器的简化模型,为后续研制及优化高性能的智能传感器提供理论参考和模型基础。建立的传感器模型具有通用性和可扩展性,能关联不同的物理接口;结合实际需求,可在该模型的基础上快速扩展构建所需的网络化智能传感器,能实现传感器的"即插即用"和实现良好的网络互操作性。

Universal modeling method and application for network intelligent sensors based on IEEE 1451

A universal modeling method for network intelligent sensors based on IEEE 1451.0 standard is presented to improve the networking interoperability of intelligent sensors.The universal network intelligent sensor frameworks including static use-case model, dynamic behaviour models and system deployment model are described by using Unified Modeling Language(UML). Then, an insulator contamination status online monitoring sensor is rapidly constructed from these frameworks. Research results indicate that the UML-based modeling method could be used to effectively describe the simplified intelligent sensor model based on IEEE 1451 standards.The model shows well universal and expandable characteristics and can correlate different physical interfaces and realize network interoperability.Moreover, the development time for IEEE 1451-based network intelligent sensors has decreased over 60% as compared with those traditional methods.
