Plant Control Hardware ID Tracking for Real-Time Part Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In plant control and monitoring systems, the replacement of component parts cannot be detected in real time using existing hardware identification systems like RFID, leading to potential operational disruptions and security risks due to unauthorized exchanges.
Innovation Solution
A system where each component part of the plant control and monitoring device is equipped with a unique ID recorded on a wireless communication chip, allowing the communication card to read and transmit these IDs through a control network to a maintenance tool for correlation with an ID database, enabling real-time detection of part replacements and unauthorized exchanges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wireless tag or RFID is used for hardware identification of component parts, then identification efficiency is improved, but real-time detection of part replacement is lost because maintenance personnel must physically visit the control device at the job spot to read identification information
Solution Approach 1:
The patent introduces a maintenance terminal as an intermediary device that connects to the control device via network. The maintenance terminal reads identification information from wireless tags on component parts and transmits this information to the server, enabling remote monitoring without requiring maintenance personnel to physically visit the control device while maintaining real-time detection capability
Solution Approach 2:
The patent implements a feedback mechanism where the server stores identification information and compares it with information transmitted by the maintenance terminal. When a component part is replaced, the system automatically detects the change by comparing the new identification information with the stored information, providing real-time feedback on part replacement status
2Device complexity
If manual note-taking is used to manage component part identity, then system complexity is reduced, but maintenance efficiency and accuracy deteriorate due to human error and time-consuming processes
Solution Approach 1:
The patent implements a self-service system where component parts are equipped with wireless tags containing identification information. The system automatically reads, stores, and manages this information without requiring manual note-taking by maintenance personnel, thereby improving maintenance efficiency while keeping the overall system architecture relatively simple
Solution Approach 2:
The patent replaces the manual mechanical process of note-taking with an automated electronic system. Wireless tags store identification information electronically, and the maintenance terminal automatically reads and transmits this information, eliminating the need for manual writing and recording processes

Data Source
AI summary
A plant control and monitoring device includes a communication card having a first wireless communication chip on which a first unique ID is recorded, a CPU card having a second wireless communication chip on which a second unique ID is recorded, an input card having a third wireless communication chip on which a third unique ID is recorded, and a power supply unit having a fourth wireless communication chip on which a fourth unique ID is recorded. The first wireless communication chip reads out a unique ID from the second wireless communication chip or the fourth wireless communication chip, and transmits a read out unique ID to a maintenance tool through a control network. In a plant control and monitoring system, when the maintenance tool receives a unique ID transmitted through the control network, the maintenance tool collates the received unique ID with an ID database.
