Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for collecting monitoring data from equipment and facilities face challenges, such as the inability to directly transmit data from conventional equipment and the limitations of data collection via external sensors.
Innovation Solution
A process data collection system that receives image data from an equipment monitoring system, extracts monitoring data by analyzing the image data, and transmits the extracted data to a process analysis system without the need for direct data transmission or external sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If direct data transmission from equipment is implemented, then data collection efficiency is improved, but applicability to conventional equipment deteriorates
Solution Approach 1:
The patent introduces an intermediary system consisting of a camera and image recognition software that captures and processes visual information from equipment interfaces. This intermediary approach enables data extraction from conventional equipment without requiring direct data transmission capabilities, thus resolving the contradiction between collection efficiency and equipment adaptability
Solution Approach 2:
The patent replaces traditional mechanical/data-based data collection methods with an optical-based system using cameras and image recognition. This substitution allows the system to collect data from equipment displays and interfaces visually, making it compatible with conventional equipment while maintaining efficient data extraction
2Reliability
If external sensors are installed on equipment, then monitoring capability is improved, but device complexity and installation difficulty increase
Solution Approach 1:
The patent creates a visual copy of the equipment's display interface by capturing images with a camera. Instead of installing physical sensors on equipment, the system captures and processes images of the equipment's existing displays, thereby obtaining monitoring data without adding physical complexity or installation requirements
Solution Approach 2:
The camera and image processing system serve as an intermediary that extracts monitoring information from equipment displays without requiring direct physical connection or sensor installation on the equipment itself, thus improving monitoring capability while avoiding installation complexity
3Adaptability or versatility
If image data analysis is used to extract monitoring data, then compatibility with conventional equipment is improved, but data extraction complexity increases
Solution Approach 1:
The system employs automated image recognition and optical character recognition (OCR) technologies that enable self-service data extraction. The camera captures display images and the software automatically recognizes and extracts data without requiring manual intervention or complex configuration, thus improving compatibility while managing extraction complexity through automation
