The core of this system lies in the real-time collection, continuous monitoring, cloud storage, and abnormal alarm of temperature and humidity data for medical devices throughout the entire circulation process, including warehousing, transportation, and distribution, through IoT sensing and cloud platform technology. It upgrades traditional manual inspection and passive remediation to digital control with full visibility and active early warning, ensuring that temperature-sensitive medical devices (such as in vitro diagnostic reagents, biological materials, implants, etc.) are always stored and transported in a compliant environment. It is a key infrastructure for the transformation of the medical device supply chain towards refined and intelligent quality management.
