In process plants, there is a need to diagnose and analyze wireless communication issues with smart devices to ensure safe operation, as electromagnetic noise or access point failures can prevent status signals from being received by the communication center, potentially leading to unsafe conditions without immediate detection.
Innovation Solution
A handheld wireless transmitter network analysis tool that receives and analyzes wireless signals, converts them into digital data, and identifies noise sources, allowing technicians to determine if smart devices are functioning correctly and identify potential interference or network issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If wireless communication is used for smart devices, then installation cost and time are reduced, but reliability of status signal transmission deteriorates due to electromagnetic noise and access point failures
Solution Approach 1:
The analysis tool performs preliminary detection of wireless signals and noise levels at the device location before technicians dispatch for inspection. This preliminary action identifies whether communication failures are due to device issues or network interference, preventing unnecessary technician trips and enabling proactive troubleshooting.
Solution Approach 2:
The handheld analysis tool acts as an intermediary device between the smart device and the communication center. It captures and analyzes wireless transmissions locally, providing intermediate diagnostic information about signal quality, noise levels, and device status without requiring direct communication center involvement for every check.
2Reliability
If technicians dispatch for inspection when status signals are not received, then device functionality is verified, but loss of time and resources increase due to unnecessary trips when devices are functioning correctly
Solution Approach 1:
The analysis tool performs preliminary detection of wireless signals and noise levels at the device location before technicians dispatch for inspection. This preliminary action identifies whether communication failures are due to device issues or network interference, preventing unnecessary technician trips and enabling proactive troubleshooting.
Solution Approach 2:
The system enables self-diagnosis through the handheld analysis tool, which can independently assess device status, signal quality, and noise levels. This self-service capability filters out cases where devices are functioning correctly but experiencing temporary communication issues, allowing technicians to focus only on genuine device problems.
3Measurement precision
If comprehensive wireless network analysis is performed, then accuracy of fault diagnosis is improved, but device complexity of the analysis tool increases
Solution Approach 1:
The handheld analysis tool is designed as a universal device that can analyze multiple aspects of wireless communication including signal presence, signal strength, noise levels, and device status. This multi-functionality consolidates what would otherwise require multiple specialized tools into a single device, achieving comprehensive diagnostics without proportionally increasing complexity.
Solution Approach 2:
The tool replaces complex manual inspection procedures with automated electronic analysis. Instead of technicians physically examining devices and interpreting communication patterns, the tool uses electronic signal analysis to automatically detect faults, reducing the complexity of human judgment and training requirements while maintaining high diagnostic accuracy.
