Description

technical field [0001] The invention belongs to wireless network communication technology, and is suitable for network management and communication technology in indoor high-density wireless environment. Background technique [0002] Ancient books are the recorders and witnesses of history and culture, and some rare books also have cultural relic value and occupy a special position in modern library collections. Among the ancient books that are circulating now, paper has become the main carrier for recording words. However, when the paper is exposed to sunlight or high temperature and humidity, the cellulose component contained in the paper is prone to oxidation and hydrolysis reactions, so that ancient books are prone to yellowing, brittleness, and brittleness. In addition, mold, silverfish, water and fire disasters are also factors that affect the protection of ancient books. [0003] Most of the existing ancient book protection boxes are stored in wooden protective boxe...
