摘要

In accordance with the present invention, the method for managing the key ejection of a contract using a smart terminal includes the smart terminal's unique information of the contract person in charge, the unique information of the beacon A installed in the vehicle, the unique information of the beacon B installed in the key vault, and the beacon attached to each contract key. The step of registering and storing the unique information of C on the management server, the unique information of the beacon A installed in the vehicle, the unique information of the beacon B installed in the key vault, and the specific information of the beacon C attached to the key of each contractor The step of registering and storing in the smart terminal, the step of installing the key management application on the smart terminal of the contractor, the step of activating the smart terminal application of the contractor, and the smart terminal of the contractor in charge open the key safe. Determining whether to receive the beacon B signal of the supplied key safe, and when receiving the beacon B signal, the step of determining that the key safe is opened (opened) by the contract person in charge, and the smart terminal by the contract person in charge. Determining whether to receive a beacon signal from beacon C attached to each of the plurality of contractor keys supplied with power when detached from the safe, and when a beacon signal of beacon C attached to any contractor key is received, The smart terminal in charge determines that any contract key is ejected, and the smart terminal in charge of the contract determines whether the beacon B signal is received, and if there is no beacon signal from beacon B, the key safe ejects the key.
