CPS is a kind of networked embedded system .Its trustworthiness and cost are impacted by energy consumption . Because software is the main component of CPS ,it is influenced by the energy consumption of CPS .So it has become a major chal-lenge for CPS development to design low-power ,high trustworthiness CPS software .Existing analysis and evaluation methods have problems such as the experimental high cost and big price .If the trustworthiness problem of software can be found in the design phase ,it can effectively reduce the cost and improve development efficiency .So modeling ,analyzing and evaluating the software ar-chitecture energy consumption of the CPS software architecture design stage can help find the energy consumption design defects .It can effectively improve the trustworthiness of the CPS software and reduce development costs .Against this ,first build the CPS soft-ware architecture energy consumption based on the energy consumption time Petri nets ;then by analyzing the trustworthiness prob-lems of the CPS software influenced by the energy consumption ,propose the evaluation method for CPS software based on the ener-gy consumption model ;finally ,indicate the effectiveness of the proposed methods through an instance .
