Digital libraries and digital museums came into being at the historic moment, and gradually became a hot spot for countries to compete for investment. However, at present, general digital museums are often designed and implemented independently according to different needs and contents, and operate in a single system environment. With the development of science and technology, a new, more intuitive and fast digital media has appeared in front of us. Compared with previous media, multimedia technology has obvious advantages. It integrates various information such as text, pictures, animation, sound, video and so on, which can be conveyed to the audience in the most convenient and intuitive form. In this paper, the digital museum reading system is analyzed and designed under the multimedia digital display system, and the process of museum system infrastructure and database design is expounded, which is beneficial to the construction and development of Hunan digital museum and also provides a reference model for the construction of information platforms in other fields.
