摘　　要：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 software 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 computer 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 system. Finally,an example and several experiments verify the validity and rationality of this model.
