Wireless Measurement Data Integration with SPC Reports
Problem Overview
Measurement results used for SPC reporting are currently entered manually by QC personnel. Re-entering values from measuring instruments increases reporting time and creates the possibility of transcription errors. The challenge is to establish secure wireless or equivalent digital connectivity between applicable measuring instruments and the SPC system so that measurement values are captured automatically in the correct report field and immediately available for statistical analysis.
Industrial Context & Background
Quality 4.0 / SPC / Instrument Connectivity
Technical Requirements
1) Support Wi-Fi/Bluetooth or suitable instrument interface
2) Correct field/characteristic mapping
3) Validate measurement units and formats
4) Prevent duplicate/incorrect transfer
5) Secure connectivity and audit trail
6) Failed-transfer notification/recovery
Suggested Technology Stack: Wi-Fi/Bluetooth; Instrument Interface; SPC Software; Database; API/IoT Gateway
Expected Solution & Prototype
1) % measurements transferred automatically without manual entry
2) Data-transfer success/failure rate measured
3) Transcription errors eliminated for directly captured values
4) Transfer latency from measurement to SPC availability measured
5) Automatic SPC statistics/control charts generated from captured data
6) Measurement traceability to instrument, part and date-time maintained
