The laboratory is one of the indispensable and important departments in hospitals at all levels, playing an important role in clinical disease diagnosis and examination. Due to the need for refrigerated processing of test reagents and patient specimens in daily work and scientific research, the management of the cold chain is extremely strict. Previous management methods have many shortcomings, consume a lot of manpower and resources, and management is cumbersome. In the current tense situation of medical staff, it has added a lot of burden to medical staff. At the same time, it will also cause frequent opening of refrigerators due to errors in manual monitoring and other issues, Forgetting to close tightly and other issues can affect the effectiveness of refrigerated management of reagent specimens.

Ocamar Wireless Cold Chain Management System Based on One Network Infinity ? The design of a medical dedicated wireless Internet of Things platform utilizes an active wireless temperature sensor to instantly grasp temperature and humidity data. Through the principles of the Internet of Things, the high-tech level of the Internet of Things is reflected from the perspectives of perception layer, wireless transmission layer, and application layer. Provide an intuitive and user-friendly human-computer interaction interface and complete auxiliary management information. The IoT medical wireless cold chain management system has many innovations, mainly applied to hospitals, sanatoriums, blood bank centers, and various medical institutions. This system adopts IoT technology and uses IoT cold chain labels to actively send monitoring data to IoT base stations, which are sent to data collection engines through IoT base stations. The system displays monitoring data in the form of curves, making cold chain supervision visual and standardized, Reduce the workload of medical staff and achieve intelligent level of cold chain management.

· Based on OneNet Unlimited? medical dedicated wireless IoT platform design.

· Composed of IoT platform technology, temperature and humidity sensors, IoT data collection engine, and visual management software;

· Place the sensor in the drug storage room or drug refrigerator, collect and monitor temperature and humidity data inside the refrigerator, and actively report the data to the backend IoT data collection engine in real time, and save it in the server database;

· The system can set upper and lower threshold values. When the temperature of the drug environment is too high or too low, management personnel will receive relevant refrigerator abnormal SMS alarms;

· The system can trace relevant historical records and historical curves, extract abnormal temperature and humidity monitoring points, and form graphic reports.
