Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital twin-based facility monitoring techniques are limited in monitoring inside facilities or surrounding situations, and their economic feasibility and efficiency are low compared to computer resources consumed.
Innovation Solution
A digital twin-based video monitoring method that strengthens connectivity with video information by generating a model object from a CPS model, converting it into a camera object, and outputting both model and video information through a control server and computer system, allowing for efficient selection and display of camera-specific video.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional digital twin-based facility monitoring techniques are used to confirm operational status and deformation of facilities, then real-time confirmation of detailed facility status is achieved, but monitoring capability inside facilities and surrounding situations is limited
Solution Approach 1:
The patent merges the digital twin CPS model with video monitoring systems by integrating camera objects into the 3D model. This combination allows the system to simultaneously provide detailed facility status confirmation through the digital twin and expand monitoring scope to include interior and surrounding areas through video cameras, resolving the contradiction between precision and versatility.
Solution Approach 2:
The digital twin platform is enhanced with multi-functionality by incorporating not only facility status monitoring but also video monitoring capabilities. The system can now perform multiple functions including operational status confirmation, deformation detection, and interior/surrounding situation monitoring through integrated camera objects, thereby improving adaptability while maintaining precision.
2Reliability
If frequent operation of CPS model using information from monitoring equipment is performed, then facility monitoring is maintained, but computer resources consumed far exceed actual monitoring effect
Solution Approach 1:
Instead of continuous frequent operation of the CPS model, the system employs periodic action by updating the digital twin model only when necessary based on camera object selections and video information. This reduces computer resource consumption while maintaining monitoring reliability through strategic, event-driven updates rather than constant operation.
Solution Approach 2:
The patent extracts essential monitoring functions from the full CPS model operation. By separating camera object management and video monitoring from the core CPS model, the system can maintain monitoring continuity through lightweight operations while reducing overall computer resource consumption by only activating the full model when needed.
3Measurement precision
If conventional digital twin-based monitoring techniques are used, then facility status can be confirmed, but economic feasibility and efficiency are low compared to computer resources consumed
Solution Approach 1:
The patent uses copying by creating simplified camera objects that represent physical cameras within the digital twin environment. These camera objects enable video monitoring functionality without requiring full physical deployment and operation of all monitoring equipment, thereby improving productivity while maintaining the ability to confirm facility status accurately through the digital representation.

AI summary
The present invention relates to a video monitoring method in an area where a plurality of CCTV cameras is installed, such as an urban area. As a digital twin Cyber Physical System (CPS) is constructed, and a control server connected to a camera and a computer connected to the control server are configured, and a model object generated from a CPS model and video information transmitted from the camera are collected in the control server and transmitted to the computer, users may confirm a digital twin-based model object together with actually captured video information. Through the present invention, it is possible to immediately and clearly confirm surrounding spaces, as well as the location of a camera transmitting specific video information in video monitoring of a wide area such as urban areas, and efficiency and accuracy of viewing the video information of a plurality of cameras can be dramatically improved.
