According to the characteristics of vaccine cold chain management, the vaccine cold chain temperature and humidity monitoring system uses the Internet of Things technology to perform real-time monitoring of the storage temperature in the middle / end of the vaccine cold chain that is currently in urgent need of enhanced management. Once an abnormality is found, an alarm is issued in time to notify the relevant personnel Take steps to reduce vaccine failure. When a vaccine cold chain accident occurs, you can determine the deterioration of the vaccine and detect it for destruction, thereby avoiding the accident. At the same time, define the problem link through data facts in order to identify the party responsible for the accident and investigate legal and economic responsibilities; even through data analysis , You can dig out the place where the accident occurred, the vehicle, the frequency of frequent operator problems.
The vaccine cold chain temperature and humidity monitoring system uses wireless temperature and humidity sensors to monitor the temperature changes during the transportation of vaccine tips, combines GPS technology to realize the unified information of cars, things, locations, and temperatures, and uses wireless communication technology to achieve real-time monitoring.
First, the composition of the vaccine cold chain temperature and humidity monitoring system :
1. Wireless temperature sensor :
It is equipped in the refrigerated warehouses of medical and health institutions in the cities, refrigerated refrigerators, refrigerated transport vehicles, and vaccine freezers in community health centers, and constantly monitors the temperature curve and wirelessly sends abnormal data.
Equipped with prefecture medical and health institutions, inoculation point warehouses, and refrigerated transport vehicles for collecting temperature sensor data and location data.
3. Cloud-based vaccine cold chain query service platform:
Cloud technology is used to realize full-scale query of vaccine cold chain data. Includes data center and SAAS services, as well as integrated monitoring and management terminal software. The data center guarantees the safe storage of data; SAAS service provides effective temperature and humidity information and other raw data for the data center, and provides a service interface for various application management software. At the same time, the service can support seamless access of various mobile terminals
Including: mobile phones, PCs, industrial handhelds, wireless temperature and humidity sensors ; comprehensive monitoring and management terminal software to provide daily management functions such as information maintenance and comprehensive monitoring for enterprises after registration confirmation.
Functions of Vaccine Cold Chain Temperature and Humidity Monitoring System:
1. Real-time monitoring of inventory storage temperature:
The wireless temperature sensor is placed in the freezer of the municipal health department and the refrigerator of the community health center (vaccination point) to monitor the storage temperature of the vaccine in real time.
2. Real-time temperature monitoring during transportation:
A wireless temperature sensor is placed in each refrigerated truck and vaccine refrigerated bag to monitor the temperature in the refrigerated bag in real time. When the temperature reaches the upper and lower limits, it can be alarmed by wireless, sound, etc., and the specific time and continuous duration of the temperature overrun are recorded. After the data arrives at the inoculation point, the handheld device is used to collect the data of the wireless temperature sensor in the refrigerator and upload the data of the transportation process to the cold chain cloud service platform through the operation network.
a. During the transportation of the vehicle, GPS + RFID reads the tag temperature in the box in real time and uploads it to the system server via GPRS;
b. The driver and the person in charge are notified by SMS when the temperature is abnormal;
c. The system authorized users can view the real-time temperature of the transportation process directly through the network.
d. When the vehicle arrives at the transport destination, before preparing for unloading, the handheld terminal displays the relevant temperature and humidity records and displays the transport temperature records to the customer;
e. The driver displays the transportation temperature for the user, and the customer confirms the temperature. The customer can check the details;
f. Drug testing is passed to the warehouse.
1, wireless identification method, no one automatically reads the temperature data;
2. Automatic monitoring of temperature sensor without human intervention;
3. Full temperature monitoring, intelligent recording, no data loss.
4. Real-time monitoring, all-weather monitoring of the ambient temperature of the vaccine during transportation, all-day monitoring;
5. Early warning management. During transportation, the monitoring ambient temperature exceeds the standard, and the system will promptly alert the user;
6. The cloud-based query management platform provides management of massive data at the provincial CDC level.
