Design and development of quality traceability system for circulation of Chinese herbal medicine based on blockchain and NB-IOT

Abstract

The safety of traditional Chinese medicine is an important issue of people's livelihood in China. The traceability process on the quality of traditional Chinese medicine is characterized by long duration, many links, and complex circulation process of traditional Chinese medicine, so the establishment and improvement of traceability system is key to the modernized development of traditional Chinese medicine. The circulation traceability system of Chinese medicinal materials, as an important part of traceability system for Chinese traditional medicine, is built according to the GSP standard by using the block chain technology to ensure the security of information circulation and the low energy consumption of NB-IOT technology, build a safe and reliable system with wide coverage and low cost technology, and provide safe and reliable technical support for the data collection and transmission. The Internet and cloud platform are used to collect, fill in and review the information in the circulation process of medicinal materials in real time. The third-party real-time validation is carried out by relying on the matter-linked sensing equipment to improve the accuracy of source information. The big data are fully used to build a portrait of integrity, crack down on counterfeit products, and maintain the brand image of authentic medicinal materials. System objects include medicinal materials distributors, government regulatory agencies and consumers, etc. By controlling each link of the drug circulation at different levels, the system strictly complies with the supply standard of traditional Chinese medicine, so as to form the information loop of the drug circulation and realize the whole-process supervision of the drug circulation. The system has user-friendly operation interface, comprehensive functions, simple and easy to use, with good portability and expansibility, which can promote all the people to participate in tracing the source, so as to develop a green and ecological chain for Chinese medicinal materials.
