Variable Frequency Drive Wireless Commissioning via Unique Identifiers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commissioning variable frequency drives requires specialized expertise and is costly due to the need for high-level engineering, as existing systems lack efficient identification and secure data transmission methods, making it difficult for less trained personnel to easily and securely adjust and program these drives.
Innovation Solution
The system employs unique identifiers for wireless data transmission equipment, allowing commissioning devices to securely and easily identify and communicate with individual variable frequency drives, eliminating the need for external experts by using pre-configured identifiers and standard devices like laptops or tablets, and enabling secure data transmission through wireless networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless data transmission equipment is used to facilitate commissioning, then ease of operation is improved, but device complexity increases due to initial identification and security requirements
Solution Approach 1:
The patent applies preliminary action by pre-configuring unique identifiers in the wireless data transmission equipment before commissioning. This allows commissioning personnel to simply select the desired drive from a list of identified devices without needing to perform complex identification procedures on-site, thereby maintaining ease of operation while managing device complexity.
2Object-affected harmful factors
If wireless data transmission equipment is used, then safety is improved by avoiding physical contact with electrical components, but device complexity increases due to security measures
Solution Approach 1:
The patent applies self-service by implementing security measures that automatically manage identification and access control without requiring complex manual security configurations. The wireless equipment handles security protocols autonomously, maintaining safety benefits while minimizing the complexity burden on users.
3Reliability
If expert knowledge is required for commissioning, then reliability of commissioning is improved, but loss of time and cost increase
Solution Approach 1:
The patent introduces an intermediary solution in the form of pre-configured unique identifiers that act as a bridge between expert-designed commissioning procedures and user-friendly operation. This allows less trained personnel to reliably commission drives by simply selecting from identified devices, maintaining reliability while reducing time loss and cost.
Data Source
AI summary
The system described herein relates to commissioning variable frequency drives of electric drive systems, where at least one variable frequency drive has wireless data transmission equipment via which the variable frequency drive is supplied with data during commissioning. A commissioning device connects with the wireless data transmission equipment of the variable frequency drive during commissioning to transmit data to the variable frequency drive. The wireless data transmission equipment of the variable frequency drive is set up before commissioning so that the variable frequency drive can be communicated with under an individual identifier specific to the respective variable frequency drive and during commissioning identification of the individual variable frequency drive is carried out by the commissioning device using the identifier.
