Abstract： With the continuous popularization and development of intelligent applications in the embedded equipment systems, higher requirements are put forward for the effective use and deep integration of big data. However, there are various types of embedded equipment and multi-source big data is heterogeneous. Due to the lack of unified organization and management, there are data barriers between business applications, and data islands have emerged, resulting in difficulties in the utilization and development of big data. Therefore, in the embedded equipment system, how to effectively organize and manage data is a difficult problem to be solved. To this end, this paper is guided by the unified management and sharing of data in embedded equipment systems. Based on edge-side and end-side collaboration technology, from three aspects: data management architecture, data hierarchical collaborative management scheme, and data request scheduling strategy, this paper discusses the feasibility of collaborative management technology for distributed data in the embedded equipment systems, so as to promote the rapid transformation of data to information, information to knowledge, and knowledge to decision-making. At the same time, this paper promotes the development of data applications in embedded equipment systems through the close combination of management and use.
Key words : data management; hierarchical collaboration; edge-terminal collaboration; distributed data
