Derui chamberQ: What data acquisition and analysis capabilities does your testing software provide?
A: All Derui DR-J series furniture testing machinery operates on an industrial-grade **PLC-based closed-loop control system** paired with an intuitive Windows PC software suite. Engineered specifically for ISO/IEC 17025 accredited laboratories and high-volume production QA, the system delivers high-speed Data Acquisition (DAQ), dynamic real-time plotting, and automated audit-ready compliance reporting.
1. Software Data Acquisition & Analytical Feature Matrix
| Software / DAQ Feature Module | Technical Specification & Hardware Basis | Engineering Application & Laboratory Value |
|---|---|---|
| High-Speed Sampling & DAQ Rate | 200 Hz (5 ms) Sampling Rate / 24-bit ADC Resolution | Captures instantaneous peak dynamic force spikes and transient structural yield without signal aliasing. |
| Real-Time Curve & Hysteresis Plotting | Multi-axis Load vs. Displacement & Load vs. Time curves | Automatically calculates hysteresis energy loss and foam firmness degradation during ASTM D3574 IFD testing. |
| Automated Pass/Fail Threshold Logic | Programmable upper/lower tolerance envelopes (±2% limit) | Auto-triggers machine safety shutdown when seat sag exceeds limits or when load cell registers zero resistance (specimen breakage). |
| ISO 17025 Audit Trail & Data Security | Encrypted SQLite database + User Role Management (Operator/Admin) | Tracks operator ID, calibration status, timestamped parameters, and raw data logs to prevent manual data tampering. |
| Hardware NVRAM Power-Loss Recovery | PLC Non-Volatile Memory auto-saves cycle state every 1 sec | Allows seamless test resumption from exact cycle interruption point after facility power outages without data loss. |
| LIMS / ERP System Integration | Automated CSV/Excel export + Optional RESTful API / Webhooks | Directly pushes batch test summaries to enterprise quality dashboards (SAP, MES, LIMS) for factory-wide QA visibility. |
2. Advanced Historical Overlay & Batch Comparative Analytics
Quality control engineers and R&D managers utilize the software’s advanced trend analysis engine to optimize raw material supplier selection and prototype engineering:
- Multi-Run Curve Overlay: Graphically overlay up to 10 historical test runs on a single screen to evaluate batch-to-batch consistency in polyurethane foam density or spring coil fatigue life.
- Automated Hysteresis Loss Calculation: During foam Indentation Force Deflection (IFD) testing on the DR-J801 Foam IFD Tester, the software automatically computes initial 25%/65% IFD values, support factor ratios, and hysteresis energy dissipation percentages per ISO 2439.
- Continuous Sag Tracking: Tracks progressive displacement loss during 300,000-cycle BIFMA X5.1 Section 8 fatigue runs, predicting structural component lifetime before catastrophic failure occurs.
3. One-Click Audit-Ready Report Generation
Generating formal compliance documentation requires only a single click. The built-in report generator creates non-editable PDF or structured Excel spreadsheets containing:
- Complete Traceability Header: Machine serial number, operator name, specimen batch ID, ambient temperature/humidity, and sensor calibration expiration date.
- Graphical & Tabular Data: Embedded high-resolution force-displacement curves alongside statistical summaries (Mean, Peak Force, Standard Deviation, Max Deflection).
- Clear Certification Stamp: Automated “PASS / FAIL” compliance verdict based on pre-set standard rules (EN 12520, EN 16139, BIFMA X5.1, ISO 7173).
🔒 Enterprise LIMS & Quality Network Integration:
For modern smart factories operating centralized Laboratory Information Management Systems (LIMS) or ERP networks, Derui software supports automated database sync via local network (LAN) TCP/IP connection or RESTful Webhook APIs. Raw test data is automatically backed up to central enterprise servers upon test completion, ensuring 100% data integrity for ISO 17025 accreditation audits.
