Problems solved by technology

The operation model of differential dynamic logic is hybrid program (Hybrid Programs, HP). Using HP to build a model for CPS is easy to verify, but the model expression is relatively abstract, and it is difficult to use it conveniently and effectively in the design process of CPS.

Embodiment Construction

[0050] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0051] refer to figure 2 , the present invention is based on the CPS-ADL model to the CPS modeling and verification method of hybrid program conversion, comprising the following steps:

[0052] According to step 1, add the declaration of time in INTERFACE of the declaration part of HYSDEL. The declaration of this part of time attribute includes two parts: the continuous time variable t of continuous state change x and the time t to input the control quantity u or T s . where the time of continuous state change t x Indicates the time of the physical entity of the current system, that is, it is consistent with the time of the physical world; and the input control quantity of the system may be a continuous input quantity u or a discrete input control quantity U, so it is necessary to declare different input...

Abstract

The invention discloses a CPS (cyber physical system) modeling and verifying method based on conversion from a CPS-ADL (architecture description language) model into a hybrid program. The method is mainly used for modeling a CPS and verifying attributes. The method is characterized in that a CPS is modeled on a CPS-ADL platform by the aid of an E-HYSDEL (expanded-hybrid system description language); a formalized definition HPM (hybrid program model) of an HP (hybrid program) model is given, and conversion rules among the CPS-ADL model elements and HP model elements are established when model conversion consistency is met; model description codes of a specific CPS are automatically converted into the hybrid program based on the conversion rules; input files of a KeYmaera are generated by the aid of the hybrid program and a dynamic differential logic description system attribute formula according to an input format of the KeYmaera of a theorem prover; the input files are opened in the KeYmaera to perform reasoning and verifying. The method and the mechanism based on conversion from the CPS-ADL model into the HP are elaborated, and the rules of conversion from the CPS-ADL model elements into the HP model elements are realized.

Description

technical field [0001] The invention belongs to the technical field of communication, and relates to a CPS modeling and verification method based on CPS-ADL model conversion to a mixed program. Background technique [0002] Cyber ​​Physical System (CPS) realizes distributed perception of the external environment, reliable data transmission and intelligent information processing by embedding perception, communication and computing capabilities in physical devices, and realizes computing entities’ interaction with physical devices through a feedback mechanism. real-time monitoring and control. CPS has a wide range of applications, including intelligent transportation systems, telemedicine, smart grids, aerospace, etc. [0003] Whether the real-time, security and reliability properties of CPS can meet the requirements is often the premise of its application in key fields. Model analysis and verification technology can determine whether the attributes of CPS meet the actual ap...
