The invention discloses an asset locating management system of cell-based narrow-band internet-of-things (NB-IoT) technology. The system includes terminal equipment, a base station and background equipment. The terminal equipment acquires asset dynamics through a narrow-band internet-of-things (NB-IoT) base-station locating, uses edge calculation to analyze risks in real time, and automatically collects and processes information of locations, status and the like; and transmits long-distance low-power-consumption data in a wireless manner through a narrow-band internet of things (NB-IoT), and regularly uploads asset data. The base station is used as a medium of information transmission of the narrow-band internet-of-things (NB-IoT) technology to realize information transmission connecting the terminal equipment and a background management system. The background equipment uses cloud computing to analyze and process received asset information to realize management of real-time asset monitoring and tracking, movement authorization, asset inventorying, security alarming and the like. According to the asset locating management system, characteristics of low power consumption, wide coverage, large capacity, short delay, frequent communication and the like of the narrow-band internet-of-things technology are utilized, the information of assets which are large in a number, high in liquidity and placed in various complex environments is accurately acquired in time, and the assets are safely and highly efficiently managed.
