Real-time monitoring solution for pharmaceutical cold chain using ARMxy + OpenPLC, featuring temperature/humidity alarms, MQTT cloud upload, GSP-compliant logs, and sensor failure detection.
Case Details
Application Scenario
Real-time temperature and humidity monitoring in vaccine transport vehicles.
System Configuration
-
ARMxy Embedded Controller
-
Y-AI Analog Input Module (collecting data from 4 temperature/humidity sensors)
-
4G Communication Module (for data upload to the cloud platform)
Implementation
-
The AI module collects data from 4 temperature and humidity sensors (4–20 mA output) every 30 seconds.
-
OpenPLC logic monitors thresholds and triggers local alarms via digital outputs when temperature exceeds limits.
-
A complete GSP-compliant log is generated, including real-time GPS location.
-
The 4G module uploads all data to the regulatory platform via the MQTT protocol.
Advantages
-
Regulatory staff can monitor the vehicle’s route and temperature/humidity trends in real time via mobile apps.
-
The Y-Series AI modules support sensor disconnection detection, improving reliability and safety.
