Embodiment

[0065] Determine the control software and obtain the function information of the control software:

[0066] Function information is function call network information, including static data, dynamic execution data and task allocation data. Use Doxygen to obtain static data, including the function call relationship network diagram and the connection relationship between network nodes and edges. The connection relationship includes the number of connections and the connection sequence; use GPROF to obtain dynamic execution data, including recording each function at runtime after the control software performs certain operations calls between them.

[0067] For visual modeling:

[0068] First, create a two-dimensional static visualization result: 1. Create a workspace to receive static analysis data; 2. Establish a network model and controller, and execute the layout; 3. Perform modular coloring and conditional filtering; 4. Add labels, adjust element colors and Size; 5. Output v...

Abstract

The invention discloses an information physical system visualization and fault positioning method based on augmented reality. The method comprises the following steps of: obtaining control software corresponding to each equipment part in the information physical system, realizing three-dimensional static visual network modeling of each equipment control software by using a static analysis tool anda modeling tool, obtaining calling times of a function in a network by dynamically executing the analysis tool, and displaying the calling times in the network; then using augmented reality techniquesto display the three-dimensional network model and the network function execution information above an equipment entity. The operation condition of the equipment part which is originally invisible orcannot be directly observed is presented in the form of a function network; the connection relationship between the equipment control software networks, the program running frequency, the program running state and the program running path are all intuitive and clear, so that technicians can conveniently know the running condition of the system in real time, timely acquire equipment control software information of the equipment when a fault occurs and make a response.

Description

technical field [0001] The invention relates to the technical field of software testing, and more specifically relates to an augmented reality-based information physical system visualization and fault location method. Background technique [0002] Cyber ​​Physical System (CPS) is a multi-dimensional complex system that integrates computing, network, and physical environment. A system may be composed of multiple smaller-scale subsystems interconnected, and various types of communication between subsystems The network transmits information, and the physical devices in the subsystem also need to be interconnected by one or more heterogeneous networks. Many failures may occur during the operation of the system. The cause of the failure may be the operation error of the control software program of the equipment in the system, the error of the associated communication between the equipment, the error of data reception and storage on the server side, etc., and the intricate relatio...
