信息物理融合系统(cyber-physical system,CPS)是集计算、 网络与物理环境与一体的复杂嵌入式系统,软件是其重要的使能部分.针对CPS软件能耗预测问题,本文从体系结构出发,构建了由计算模块、 通信模块与控制模块为顶层的基于层次着色Petri网的CPS软件能耗模型.在层次着色Petri网模型的基础上,提出了分层并行最小能耗算法,有效地提高了复杂系统的能耗计算效率.最后通过实例,并与其它能耗模型进行对比,验证了该模型的有效性和合理性.“,”Cyber-physical system ( CPS) is a complex embedded system integrating computer, network and physical environment. The software is an important enabled part of CPS. Given the energy consumption of CPS soft-ware forecasting problem, this paper constructs an energy consumption evaluation model for CPS software based on hierarchically-colored Petri nets from the system structure, whose top level is composed of a comput-er module, a communication module and a control module. The algorithm of hierarchical parallel in minimum energy consumption effectively improves the energy consumption computational efficiency of the complex sys-tem. Finally, an example and several experiments verify the validity and rationality of this model.
