Automated Trace Data Recording for Motor Control Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Analyzing trace data from equipment related to motor control is complex and prone to errors due to the current manual transmission process, which involves users sending data to operators and then to manufacturers, leading to potential mistakes and increased complexity in handling user inquiries.
Innovation Solution
A trace data recording system that automatically generates, transmits, and records trace data to a cloud server, linking it with alarm information and user/equipment identification, allowing for easy analysis by analysts without manual intervention, and providing relevant data only when an alarm is generated or upon request.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual transmission process is used for trace data, then users can send data to operators and manufacturers, but handling complexity and error probability increase
Solution Approach 1:
The equipment performs self-diagnosis and automatically transmits trace data to the server when an alarm occurs, eliminating the need for manual data collection and transmission by users. The system serves itself by detecting failures and initiating data transmission autonomously.
Solution Approach 2:
The manual mechanical process of users copying and sending data is replaced by an automated electronic transmission system. The trace data transmitting unit automatically sends data via network communication, substituting the manual mechanical handling process with an automated electronic system.
2Loss of information
If all trace data is transmitted to server, then complete analysis information is available, but data transmission time and network bandwidth are consumed
Solution Approach 1:
Only the necessary trace data related to the alarm is extracted and transmitted to the server. The system identifies and sends only the relevant data portions required for analyzing the specific alarm condition, rather than transmitting all accumulated trace data.
Solution Approach 2:
The system transmits a partial set of trace data that is sufficient for alarm analysis rather than the complete data set. By transmitting only the necessary portion of data related to the alarm event, the system achieves adequate analysis information with reduced transmission overhead.
3Productivity
If automatic trace data transmission is implemented, then analysis speed improves, but system complexity increases
Solution Approach 1:
The control unit performs multiple functions: it monitors equipment operation, detects alarm conditions, generates alarm information, and triggers trace data transmission. By consolidating these functions in a single control unit, the system achieves automatic rapid transmission without proportionally increasing overall system complexity.
Solution Approach 2:
The alarm information generation and trace data transmission functions are merged into an integrated automated process. When an alarm is detected, the system combines the alarm data with relevant trace data and transmits them together as a single package, streamlining the overall system architecture.
