In order to comply with the trend of office modernization and informatization and enhance the management level of electronic archives, an electronic archives classification management system based on single tag RFID is designed. Use RFID (radio frequency identification) to build the framework of data and archives information management system, realize RFID data storage and transmission through the central database and terminal manager module, and complete the daily operation and maintenance of electronic archives classification management by using four modules: document management, archives management, development and utilization and system maintenance; Fuzzy clustering algorithm is introduced to extract the information entropy of electronic archives data, association rules are used to realize electronic archives data fusion and autonomous scheduling, feature decomposition of electronic archives data running state information, and a classifier is established through neural network to classify electronic archives. The experimental results show that the system realizes high load balancing, low CPU utilization, and has the advantages of high accuracy and fast response rate in classification management.
