Abstract: An object acquiring system includes a cloud center, a target device disposed on an object, a host device, and a plurality of acquiring and tracking devices. The target device is provided with an ID. The host device registers an object account database, according to the ID, in the cloud center, and records a state message for the target device in the object account database. When receiving the ID transmitted by the target device, the acquiring and tracking devices log in the cloud center to check the state message, and determine whether to report the geolocation, and/or the time the ID is received, to the cloud center. The geolocation and the time information, reported by the acquiring and tracking devices, are used to track the moving trace of the target device, so that the object can be quickly located when straying or getting lost.
