In the small and medium-scale software, the object and the cooperation relation between the objects can meet the requirement. However, as software scales up and complexity increases, the cooperation emphasized by object-oriented technology shows another extreme characteristic — complexity caused by too high coupling. There is a need for a new approach to remedy the weaknesses of object-oriented technology. Large-scale software is primarily characterized by complexity. A more typical example is an item of integration. Software systems need to integrate a wide variety of hardware, legacy systems, external interfaces. Different hardware interfaces, different operating systems, different languages, different platforms, different databases, different message middleware, and different network media may be encountered. These all make the system very complex. The abbreviation for component programming is COP. COP is a complement to OOP, helping to achieve a more excellent software structure. The granularity of the components may be large or small, depending on the particular application. The COP idea is adopted, the system is regarded as individual components, and the construction of the system is completed by defining the cooperation relationship (through services) among the components. This has the advantage of isolating changes, making the system reasonably partitioned. The meaning of a framework is to define the way in which components are organized.
The micro-service technology is introduced, vaccine tracing supervision services are packaged into components, rapid fusion with other platforms and cross-platform calling can be realized, and the advantages of rapid deployment, rapid upgrading and non-stop service upgrading system implementation of project implementation are improved.
This model provides a modular solution to functions that are difficult to implement using monolithic coding, whereby a single service is easy to develop, understand and maintain. And due to the characteristics of the API, the development technology can be freely selected to provide the API service. The system is better butted with various systems, each micro service is independently deployed by the micro service architecture mode, and the influence of other service deployment on the service is not needed to be coordinated. Such changes may speed deployment, making continued deployment possible. Finally, this architectural model allows each service to be extended independently. We deploy benefits that meet the demand according to the size of each service. Even more, we can use hardware that is more suited to the service resource requirements.
And linking the data of the links of vaccine production, cold chain storage, cold chain distribution and inoculation based on the block chain technology, preventing data tampering and verifying the authenticity of the chain data. The block chain is formed by butt joint of a space information block chain basic system serving as a bottom system and a vaccine tracing supervisory system. And the production data of the vaccine, the code data of the drug supervision code, the storage and distribution data, the inoculation data, the AEFI (adverse reaction) data and the effect evaluation data are subjected to chain storage, so that the authenticity of marketing data is ensured. The risk of artificially tampering vaccine information is reduced. According to the characteristics of vaccine or vaccine supervision business, a credible, controllable and extensible vaccine supervision block chain is established, the problem that the local area network architecture applied by the block chain is high in cost at present is solved, the development, deployment, operation and maintenance, intercommunication and supervision costs of the block chain application are reduced, and the block chain is rapidly popularized and developed in vaccine supervision.
By utilizing a blockchain and Internet of things technology, traceability and non-tampering of the whole vaccine production process are realized, and the trust problem in the traditional traceability system is solved; under a consensus mechanism, all parties participating in the vaccine ecological chain carry out cooperative supervision on the whole chain to prevent ' unique ' dark box operation '; the block chain intelligent contract realizes real-time supervision, the problems are tracked in real time, and effective responsibility tracing is realized, so that common people are relieved; and storing the Hash chain of the vaccine full life cycle data, and verifying the obtained vaccine data by a monitoring party and the public through a verification contract.
Vaccine data are collected from different links, various risks are analyzed to supervisors through filtering, analysis and deep mining, the supervisors can do corresponding treatment in advance, and risks of various links of the vaccine are reduced.
A layered design module: the design comprises an application layer, a framework layer and a basic layer, and the code or variable at the topmost layer can cover the lower layer;

By adopting the technical scheme, if vaccine problems occur, the arteries and veins of the vaccine with the problems can be easily checked. And (4) using the Internet of things to punch an RFID label on each vaccine. Only a reader is needed to sweep, and relevant information is recorded or read, so that the workload is greatly reduced. In addition, the block chain technology adopts a multi-center or centerless system, and a central processor does not exist, so that data is difficult to tamper or delete. The national drug administration for the approval of vaccine production, the vaccine-producing enterprises, the vaccine-selling distributors, the vaccine-purchasing disease control centers at all levels, hospitals, and finally vaccine users are all incorporated into this system. Before a vaccine is qualified through production inspection and is ready to be put on the market, a manufacturer firstly inputs the vaccine into a system. With the circulation of vaccines in marketing activities, the system is entered at each step. Finally, all information within this system can be shared by the various entities, except the final vaccine user, entered by the hospital using the vaccine. Problems with the vaccine can be easily ascertained by the system as to which units and individuals have taken the vaccine and at which stage problems may occur. If a problem is found with a certain batch of vaccine, it is also convenient to find out which consumers used the batch of vaccine.
According to the method, an industry public chain is designed according to the characteristics of the vaccine and pharmaceutical industry, after an enterprise adopts the chain, the production flow of each product can be inquired, each product has a unique two-dimensional code, and any person can check all links from production, to a distributor and to transportation by using a mobile phone. Vaccine data need combine artificial intelligence and big data technology, integrate the data and classify, public chain of block chain vaccine, and data no longer rely on artifical record, but upload in real time, have avoided the record to make the fake problem, and the quality has the problem to ensure to discover very first time.
The block chain technology is used for realizing decentralized supervision, and a long-acting mechanism for vaccine safety management is formed. Data on an enterprise production line is linked up in real time, and any person can check the data at any time and cannot tamper, so that tampering of original data is avoided, supervision and inspection are avoided, and the occurrence of things damaging the society is avoided. With the blockchain decentralized, no officer can be right to rent, including industry experts, media reporters, competitors, and even ordinary people, can view the relevant data at any time. Meanwhile, government agencies need to monitor the production and use of vaccines more powerfully, and need to 'punch and disorder' illegal production and operation behaviors, so that industry development is standardized by stricter production standards, stricter normal monitoring and more serious illegal punishment, and the trust of the public on the vaccines is guaranteed.
