Solution Overview
Problem
Existing factory energy management systems (FEMS) face challenges in efficiently configuring networks for energy monitoring and management due to the limitations of wired communication in industrial environments, which are often affected by external factors like metal, dust, and vibration, and lack an optimal approach to select suitable communication schemes for different processes.
Innovation Solution
A method and apparatus for configuring a network of a FEMS by generating a communication adaptability matrix based on a communication characteristic matrix and a correlation matrix, which involves setting parameters such as low OPEX, CAPEX, flexibility, data rate, reliability, and latency, and determining the most suitable communication scheme for each process using these matrices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired communication is used for resource/device monitoring and control in factories, then reliability is improved, but device complexity and installation cost increase
Solution Approach 1:
The patent changes the communication parameter from wired to wireless, transforming the physical connection state while maintaining communication reliability through protocol optimization and error correction mechanisms designed for wireless environments
Solution Approach 2:
The patent creates a universal communication framework that can handle multiple communication schemes (wired and wireless) through a unified configuration approach, allowing the system to adapt to different process requirements without requiring separate configuration methodologies
2Stability of the object's composition
If wired communication is used in industrial environments with metal, dust, and vibration, then stability is improved, but ease of operation deteriorates
Solution Approach 1:
The patent changes the operational parameter from physical connection to wireless communication, eliminating the need for manual cable handling and physical network setup while maintaining stable communication through robust wireless protocols
Solution Approach 2:
The patent implements automatic network configuration where the system self-optimizes communication parameters and selects appropriate communication schemes without requiring manual intervention, making the system easier to operate while maintaining stability
3Device complexity
If a single communication scheme is used for all processes, then device complexity is reduced, but adaptability deteriorates
Solution Approach 1:
The patent segments the communication system into process-specific communication schemes, allowing different communication methods to be applied to different processes based on their specific requirements, thereby achieving adaptability without significantly increasing overall system complexity
Solution Approach 2:
The patent implements a dynamic communication configuration where the system can adaptively select and switch between different communication schemes based on real-time process requirements, maintaining simplicity through automated decision-making while achieving high adaptability
4Loss of time
If communication schemes are selected without systematic analysis, then configuration time is reduced, but manufacturing precision deteriorates
Solution Approach 1:
The patent performs preliminary analysis and evaluation of communication schemes before final selection, using systematic criteria to pre-assess the suitability of different communication methods for each process, thereby ensuring accurate selection without extending the actual configuration time
Solution Approach 2:
The patent implements a feedback mechanism where the system evaluates the performance and suitability of communication schemes based on process requirements and selects the optimal scheme, ensuring precise selection through systematic analysis while maintaining efficient configuration timing
