The invention relates to an asset management method, device and system, computer equipment and a readable storage medium. The asset management method comprises the following steps: receiving network segment registration information corresponding to a target network segment issued by a master station, wherein the network segment registration information comprises a network segment identifier; according to the network segment identifier, performing network scanning on the target network segment to obtain asset information in the target network segment; and if it is identified that the asset corresponding to the asset information is an unregistered asset, uploading the asset information and the network segment identifier to the master station, so that the master station registers the asset under the target network segment according to the asset information and the network segment identifier. By adopting the asset management method, the problems of low asset management efficiency and low management reliability caused by the fact that asset data registration is carried out by manually submitting a newly-built form in a monitoring center can be avoided. According to the invention, assetmanagement efficiency and management reliability are improved.
