Design And Implementation Of Decentralized Vaccine Traceability System

After the illegal vaccine cases in Shandong were exposed,the State Council requested that the flow and use of the problem vaccine be seriously investigated and the relevant regulatory system of the vaccine market should be improved as soon as possible.Subsequently,the State Food and Drug Administration issued the "Decision on Amending the" Quality Management Specification for Pharmaceuticals(GSP)"".In the finalization of the GSP revision,the electronic drug regulatory system was modified to a drug traceability management system,emphasizing drug manufacturing enterprises and operations.Sales companies,etc.must be responsible for quality,and a drug traceability system should be established to effectively realize the source,traceability,and accountability of vaccine drugs.Due to the particularity of its commercial characteristics,the vaccine has a fast circulation,short cycle and strict storage and transportation conditions.At present,there is no complete and effective traceability system in China.The existing traceability mechanism of the enterprise generally adopts the radio frequency identification technology(RFID)based on the Internet of Things technology or the drug identification code as the information carrier,and then establishes a self-centered traceability system through self-built or actively providing data to third parties.The data collection and management of this type of system is mainly done manually by the enterprise,which forms a self-retrospective and self-supervising model with no separation of powers and responsibilities.The manual operation method has large errors and is easy to falsify data,resulting in a low system credibility.Through tracing,enterprises can achieve commodity and logistics management,supervision and accountability by regulatory authorities,and consumers can protect their lives,health and safety.This traceability system mainly includes hardware mechanical structure,LAMP server platform,LBS location service self-built library and GPRS module,etc.,which together realize the whole traceability of vaccine from production workshop to consumers.The design of the hardware mechanical structure eliminates the brute force and imitation of the traceability system.The mechanical structure must break through the dependence on the existing electronic technology and strive to achieve the best results with the simplest and most original design;the LAMP server platform undertakes data management and users Interaction,system operation and other functions,the server as the core component of the system function,not only has to undertake a lot of automation,but also to achieve efficient operation to ensure the efficiency of the entire system;the establishment and expansion of the LBS location service self-built library improves the performance of the system,The added value of the system is added,this functional design should draw on the supplier's method,cleverly use the construction of the database to complete the functional requirements;GPRS module,etc.from the selection of components to the overall scheme design are specific to the specific traceability system Optimize the design of the environment and problems to ensure the performance and practicality of the hardware module.As a mature generation of communication,its stability and popularity can be perfectly applied to this system,and it is also the optimal choice for the system.The whole system adopts "Automatic" working mode to prevent human interference,the separation of responsibilities and responsibilities of the main body of responsibility,the data information is open and transparent,the hardware automatically acquires and transmits the relevant data,and the server and database manager are responsible for managing and maintaining the data,which improves security and trust Degrees and empowerment management belong to the supervisory department to achieve the system's efficiency,speed,accuracy and independence.
