Patent number: 8872630Abstract: Embodiments of the present invention provide an apparatus and a method for cabinet asset management and a cabinet system. The apparatus for cabinet asset management includes a management unit and at least one antenna board unit. The management unit sends a read signal to the antenna board unit. After receiving the read signal, the antenna board unit sends the read signal in a form of an electromagnetic wave, so that after sensing a magnetic field signal, a label within a radiation range of the electromagnetic wave sends, using an induction current, configuration information of a physical component stored in the label to the antenna board unit. After receiving the configuration information, the antenna board unit reports the configuration information to the management unit. After receiving the configuration information reported by the antenna board unit, the management unit performs data analysis processing.Type: GrantFiled: October 26, 2012Date of Patent: October 28, 2014Assignee: Huawei Technologies Co., Ltd.Inventors: Weifeng Duan, Qingyin Fang, Zhen Luo, Shen Tian
