Drive System Telegram Recording for In-Operation Measurement Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for obtaining measurement data from drive systems during ongoing operation are limited, as they require a test operating mode and cannot be used during continuous system operation, which hinders early identification of potential issues and prevention of unplanned downtime.
Innovation Solution
A method for data communication between a control unit and a drive system using a telegram that includes instructions for recording actual values and system behavior, allowing for continuous measurement data collection via a bus connection, with the ability to initiate measurements and parameterize recording settings remotely using cloud computing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a function generator is used to determine measured data, then measurement data can be obtained, but only in test mode and not during ongoing plant operation
Solution Approach 1:
The drive system performs self-measurement and self-recording of actual values during normal operation. The drive system itself generates and records the measurement data without requiring external test equipment, enabling continuous monitoring during ongoing plant operation rather than only during test modes
Solution Approach 2:
The measurement and recording process operates continuously during normal drive system operation. The control unit continuously receives actual values from the drive system and stores them in memory, allowing measurement data collection to proceed without interruption throughout the entire operational lifecycle of the plant
2Reliability
If measurement data is collected during ongoing operation, then early problem identification is enabled, but system complexity increases
Solution Approach 1:
The control unit serves multiple functions: it controls the drive system operation, receives actual values from the drive system, stores measurement data in memory, and transmits data to external systems. This multi-functionality eliminates the need for separate dedicated measurement and data collection hardware, reducing overall system complexity while enabling continuous monitoring
Solution Approach 2:
The patent combines the measurement data collection function with the existing control unit and drive system architecture. The control unit integrates both control operations and measurement data acquisition, merging previously separate functions into a unified system that reduces complexity while maintaining monitoring capabilities
