【摘要】：物联网的基本功能是感知物理环境,并根据实时的感知信息和用户的执行需求实现对物理环境的控制.因此,感执模块是物联网软件的核心模块.为最终将软件体系结构应用于物联网软件的开发,在基于物理模型的物联网软件体系结构(physical-model driven software architecture,简称PMDA)研究的基础上,对PMDA中的感执模型SEM进行求精,求精后的感执模型称为R-SEM.R-SEM考虑了物联网的特有属性,将SEM的内部构件按照物理应用的感执工作流程分解为用通信顺序进程(communication sequential process,简称CSP)表达的子构件来说明构件端口的功能实现,并采用CSP中的导管运算符来说明子构件的端口与构件的端口之间的同步,通过CSP描述了子构件与子构件之间的交互.使用进程分析工具(process analysis toolkit,简称PAT)对R-SEM进行了验证.验证结果表明:R-SEM中子构件之间的交互、子构件的端口与构件的端口之间的同步保持了SEM所具有的保证物理应用之间有效互联的性质——不死锁、不中止和不发散.由于R-SEM精化了SEM的内部组成,且保持了SEM的有效互联性质,因此,R-SEM对最终将PMDA应用于物联网软件的开发具有实际的指导意义.
[Abstract]:The basic function of the Internet of things is to perceive the physical environment and realize the control of the physical environment according to the real-time perceptual information and the user's execution requirements. Therefore, the perception module is the core module of the Internet of things software. In order to apply software architecture to the development of Internet of things software, physical-model driven software architecture, a physical model-based software architecture, is used to refine SEM in PMDA. The refined perception model called R-SEM.R-SEM takes into account the unique attributes of the Internet of things, The internal components of SEM are decomposed into sub-components expressed by communication sequence process communication sequential process according to the workflow of physical application to explain the function realization of component port. The synchronization between the ports of the sub-components and the ports of the components is explained by using the catheter operator in CSP, and the interaction between the sub-components and the sub-components is described by CSP. Process analysis tool kit (path) is used to verify R-SEM. The verification results show that the interaction between the: R-SEM neutron components and the synchronization between the ports of the sub-components and the ports of the components maintain the properties of SEM which guarantee the effective interconnection between physical applications-no deadlock, no stopping and no divergence. Because R-SEM refines the internal composition of SEM and maintains the effective interconnection property of SEM, R-SEM is of practical significance for the final application of PMDA in the development of Internet of things software.
