基于组件的信息物理系统描述语言

摘要

本文设计实现了一种基于组件的信息物理系统描述语言CDL(CPS Description Language).基于面向参量模型,将信息物理系统中的传感器、执行器和计算组件封装成具有统一抽象的组件,将系统描述分解为系统中包含的组件、组件之间的关联以及系统约束三部分.实现了基于CDL的信息物理系统的设计实现工具,提供CDL生成、验证和安装的功能.最后设计实现了两个应用实例,验证了通过CDL来实现系统,可以减少开发者编写的代码量,提高编程效率,一定程度上降低系统设计实现的难度.%This paper presents a component-based language named CDL (CPS Description Language) to describe Cyber-Physical Systems according to the actor-oriented model. The sensors, actuators and compute components in a Cyber-Physics system are encapsulated into components with uniform abstraction. Therefore, a system description is decomposed into the components contained in the system, the directed relationships between components, and the system constraints. In addition, we design and implement the development tool of CPS based on CDL, which provides the functions of system description generation, verification and installation. At last, two system examples are implemented to prove that the amount of code written by developers could be reduced and the efficiency of programming could be improved to a certain extent by using CDL.
