Traditional Chinese Medicine (TCM) is the crystallization of Chinese medical heritage for thousands of years and plays a huge role in human health. How to integrate TCM products with modern information intelligent production means to efficiently obtain standardized Chinese medicine services is a very worthy research direction. In this paper, the decocting service of TCM is taken as the research object, and combined with artificial intelligence, blockchain and other information technologies, an intelligent service system for trusted collaboration in the whole process of decocting TCM is innovatively proposed and designed. Under the intelligent collaboration of a variety of decocting devices, key links, such as automated prescription business management, intelligent dispensing and decocting, and blockchain-based quality monitoring, were studied, and collaborative decision-making optimization and information trusted traceability of the whole process of decocting Chinese medicine were realized. The service system was applied in a Chinese medicine piece processing company, realizing the ability to handle 880,000 prescriptions annually, 144 decocting stations with intelligent collaboration, and 35 indicators with full process traceability. The practice shows that the system can realize the trusted intelligent cooperation of the whole process of Chinese herbal decoction.
