The invention relates to the field of warehouse management and specially relates to a low-power-consumption network adaptive warehouse management system. The system has RFID (radio frequency identification) tags matched with materials in a warehouse, positioning gateways, a warehouse gateway, a dynamic management cloud platform and an application operation platform. The positioning gateways and the RFID tags are in bluetooth communication; each positioning gateway is in match communication with multiple RFID tags; the positioning gateways and the warehouse gateway are communicated through LoRaWAN protocols; the warehouse gateway and the dynamic management cloud platform are in wired network or 4G wireless communication; the dynamic management cloud platform has a material database; and the material database internally stores information of each material in the warehouse. The low-power-consumption network adaptive warehouse management system has the advantages of low power consumption, high positioning precision and convenient arrangement and the like, realizes automatic optimization identification and matching between the positioning gateways and the RFID tags through a global adaptive dynamic coding and global optimal active handshake positioning mode, greatly reduces labor maintenance cost, and has an excellent promotion prospect.
