1. Statutory Mandates of TCVN 13990:2024 & HACCP in Cold Chain Logistics
National Standard TCVN 13990:2024 and international HACCP / Good Storage Practice (GSP) standards mandate continuous, tamper-evident recording and auditable traceability of thermal environments across cold storage and transport:
Cold Chain Vulnerabilities & Manual Logging Bottlenecks
In vaccine cold rooms (+2°C to +8°C), biological pharmaceuticals, deep-freeze export seafood facilities (-18°C to -25°C), and reefer containers, manual paper logbooks present severe operational blind spots: zero after-hours excursion alerts, human transcription errors, and total data loss during power outages.
A single undetected compressor stall or container door seal failure lasting mere hours can destroy multi-million-dollar pharmaceutical batches or trigger immediate revocation of HACCP/GSP certifications and export cargo rejections.
2. VTI Corp Automated Wireless Cold Chain Architecture
An end-to-end telemetry system optimized for harsh sub-zero storage and extreme humidity environments:
VTI-TS-22 (TBR22-ST) & Multi-Sensor Environmental Telemetry (uuidEnvi)
VTI-TS-22 wireless contact probes and ambient environmental nodes measure temperature and relative humidity simultaneously (mapped via Modbus TCP 40000 + i*6). Delivering ±0.2°C precision across -40°C to +125°C, high-gain 2.4 GHz BLE Mesh signals penetrate 150mm polyurethane insulated sandwich panels up to 100 m without piercing refrigeration envelopes.
Zero Data Loss SD Buffering & Automated Resync Handshake
The EDGE GATEWAY GW01 / GW22-D incorporates on-board industrial SD storage buffering all sensor frames. Under normal conditions, telemetry is dispatched every mqttSendInterval = 180s to aiplatform.vn:1883 via MQTT QoS 1. During network or cellular outages, readings are safely buffered to local solid-state storage. Once connection restores, the gateway automatically flags a Resync state to back-fill historical data, preserving an unbroken HACCP audit log.
On-Site Alarms & WhatsApp Automation (CallMeBot API)
The instant temperatures drift outside HACCP tolerances (e.g. rising above +8°C in vaccine cold rooms or above -18°C in frozen logistics), local audio/visual alarms trip while an automated CallMeBot API fires WhatsApp alerts directly to warehouse supervisors (configured via waPhone / waApiKey, bundling up to 6 sensors per message with 15-minute anti-flood throttling).
3. Technical Compliance Mapping: TCVN 13990:2024 & HACCP Standards
Clause-by-clause compliance verification mapping cold chain standard requirements against VTI Corp system specifications:
| Standard Clause & Mandate | TCVN 13990:2024 / HACCP Requirement | VTI Corp Solution Compliance |
|---|---|---|
| Sensor Temperature Accuracy | Maximum permissible measurement error must not exceed ±0.5°C across operating range. | Exceeds Standard (±0.2°C): VTI-TS-22 metrology precision of ±0.2°C with ISO/IEC 17025 calibration certificates. |
| Data Integrity & Tamper Resistance | Continuous automated logging with immutable audit trails stored for 1–3 years minimum. | Fully Compliant: Edge SD buffering + encrypted cloud storage on VTI AI Platform with immutable timestamps. |
| Offline Resilience & Reconnection | Must maintain autonomous local logging during network outages and resynchronize without loss. | Automated Resync Protocol: Gateway auto-engages Resync flag upon reconnection, back-filling buffered readings. |
| Real-Time Excursion Alerts | Immediate multi-channel alarms triggered upon thermal threshold excursions. | Instant Multi-Channel: Local audio/strobe + automated WhatsApp messages via CallMeBot API to personnel. |
