Positioning management and control system for controlled article and holder thereof

The invention discloses a positioning management and control system for a controlled article and a holder thereof. The safety state of the important article and the holder thereof in the combined movement process can be reflected in real time and can be prompted and alarmed. The technical scheme comprises the steps that the pairing relation is established between the electronic tag of the controlled article and the mobile terminal of the holder, and the tag reader arranged on the mobile terminal detects whether the distance between the controlled article and the holder thereof exceeds the management and control distance based on the signals read from the electronic tag so as to notify a management and control platform. When the pairing relation of the electronic tag and the mobile terminal is relieved, the controlled article enters an in-store mode and establishes the pairing relation with a storekeeping terminal, and the storekeeping terminal uploads pairing information to the management and control platform and alarms to the management and control platform when the pairing relation is damaged. The position abnormality of the controlled article can be immediately alarmed so that timely communication between the important articles can be further realized, the efficient and linkage movement combination is formed and the higher level of safe use and management and control requirements can be realized.
