Design and implementation of cloud service system for cold chain logistics of fresh agricultural products based on component integration

Abstract: The information service for cold chain logistics of fresh agriculture product can effectively reduce the loss and improve distributing efficiency, and many researchers have been committed to the area and obtained fruitful results. But current related research achievement can't be popularized in large areas due to the research cost and response speed to user's individualized requirements. Referring to the existing research, this study made an in-depth investigation and analysis of information requirement in 12 enterprises which were engaged in the cold chain logistics of fresh agricultural products, and designed a public service system for cold chain logistics of fresh agricultural product based on cloud service and component integration. The public service system was divided into 3 parts, i.e. the data center which managed the business data and established a standard communication protocol for the access of iot (Internet of things) monitoring equipment; the component center made up of multiple web components, each of which was an independent functional unit such as vehicle monitor, real-time warning and order playback, and enterprise users could choose the corresponding components according to their actual needs; the application release center, which published the personalized system for different users by recognizing the authentic identity and integrating the business components, and rapidly responded to user needs through cloud services. Since 2013, the application of public service system for cold chain logistics of fresh agricultural product was displayed in Beijing, Shanghai and Xinjiang. The system provided information solution of cold chain logistics for 12 enterprises and the services covered production, processing and distribution of agricultural products. Through cloud service technology, the data center and component center were deployed in National Engineering Research Center for Information Technology in Agriculture, and users managed the vehicles, orders and other types of data by using web plug-ins and applications. The practical application result showed that the customization and combination of components could quickly respond to the individual needs of different enterprises. The way of cloud service made multiple users to share the costs of research and development of the system, so it was possible for small and medium enterprises to get high quality information service for cold chain logistics with a lower cost. Meanwhile, the system cloud flexibly docked with the tripartite system by using standard data communication protocol such as JSON and Http, and it was convenient for enterprise users to complete the integration between customized components and their own system without the unnecessary duplication of efforts. In a word, the research results in this paper provide an available solution for the information service for cold chain logistics and give a good experience for the popularization of agricultural information application system.
