1. Overview of business process:
RichonTech Vaccine Management System is a real-time asset and temperature management system based on RFID and WSN technology; RFID technology is used to mark all the information of each box of vaccine in the process of vaccine transportation, inventory, and distribution, and real-time temperature recording, tracking and analysis of vaccines are realized through WSN technology. ；
1.1 Storage
According to the purchase details of the purchase order, after receiving the delivery from the manufacturer, paste an RFID tag (or barcode) in each vaccine box. The RFID tag contains all vaccine information such as the vaccine variety, supplier, and expiration date;
When the vaccine box is sent to the cold storage, a handheld RFID device is used to associate the vaccine box with the storage location. The storage location is marked with an RFID tag, and the cold storage can be divided into different virtual locations according to the size of the cold storage in a matrix manner;
1.2 Real-time temperature monitoring
Place active RFID temperature tags in key parts of the cold storage. The RFID temperature tags monitor the temperature of the cold storage in real time according to the system requirements, and transmit the temperature information to the management center in real time through the WSN network. The management center can see the temperature information of all locations in the cold storage in real time , And when the temperature exceeds the preset temperature value, the system will automatically alarm;
1.3 inventory
Vaccines must be shipped out in strict accordance with the first-in first-out management process. Therefore, the daily inventory is to ensure that the vaccines in the inventory completely correspond to the information in the system; during inventory, the staff use the handheld RFID reader to read the cold storage location tags, and then Read the RFID tag (or barcode) on the vaccine box to realize the database of real inventory information. The inventory data is transmitted to the vaccine information management system through the wireless WSN network to achieve paperless and real-time inventory inventory;
1.4 Delivery
According to the outgoing principle stipulated in the vaccine use management method, the location of the vaccine that needs to be out of the warehouse is queried through the system (identified by the RFID tag of the cold storage location), and the vaccine box that needs to be out of the warehouse can be located. The staff uses the handheld device to check the vaccine box. The label achieves the purpose of strict delivery;
1.5 Transportation
For bulk vaccines that need to be transported over long distances, active RFID temperature tags are used in cold storage trucks to monitor temperature changes during transportation in real time, and transmit real-time data back to China and the West through GPRS/3G communication methods to ensure that they are in transit Meet the storage requirements of vaccines.
2. Function description
RichonTech vaccine management system adopts radio frequency identification RFID and wireless sensor network (WSN) technology to realize the whole process management of vaccines from storage to use. It not only manages the distribution and transportation of the vaccine, but also tracks the temperature in real time; realizes the maximum vaccine Automation and wireless management; meet the requirements of vaccine management modernization;
2.1 Temperature vaccine monitoring
The system can manage the temperature of each box of vaccine, and can view the temperature change of each box of vaccine in each process in real time;
2.2 Analysis of vaccine inventory data
Through the RichonTech vaccine management system, key information such as inventory data and vaccine dynamics can be analyzed in real time; it is of great significance for ensuring the validity of vaccines;
3. Technical description
The core technology used in the RichonTech vaccine management system is to use our own intellectual property rights active RFID temperature tag. This cold chain tag can realize real-time temperature data collection and real-time transmission of temperature system functions via wireless network. It uses an ultra-thin button battery It can be guaranteed to work normally for three years;
All data collection does not need to be touched, and the active RFID temperature tag can achieve data transmission of 300 meters. By following the central wireless data node in the cold storage, the staff can view all the temperature data in the cold storage in real time in the office;
When our system is connected to the Internet, the monitoring center can also monitor real-time information in different places;
During the transportation process, the temperature data collected by our tags can be transmitted to the monitoring center in real time through the wireless transmission platform (GPRS/3G) provided by the operator, so that the staff can view the transportation in the monitoring center. Vaccine temperature data on the way;
