An article anti-lost device comprises a plurality of sensors and a host. Each sensor comprises a recognition module and a sensor signal transceiver module. The host comprises a control module, a host signal transceiver module, a host warning module, an operation module and a display module. In an article anti-lost method, the host and the sensor are firstly paired, and then the sensor is combined with a to-be-monitored article and a warning distance is set. When a distance between the sensor and the host exceeds the warning distance, a warning signal is outputted, and an orientation and a distance of the sensor are prompted on the host. With the structure and the method, when the article leaves the user by a predetermined distance, the user can be reminded to prevent the article from getting lost or stolen. |

1. An article anti-lost device, comprising:
a plurality of sensors apt to be combined with a to-be-monitored article and be carried along with a monitoring person, wherein each of the sensors comprises a recognition module having identification data and a sensor signal transceiver module connected to the recognition module; and a host, comprising a control module having logic, operation and storage functions and a host signal transceiver module, a host warning module, an operation module and a display module, which are connected to the control module, wherein the control module can transmit and exchange signals with the sensor signal transceiver module and the recognition module of the sensor through the host signal transceiver module, so that the sensor and the host are paired to form a unique correlation, and a distance between the sensor and the host can be judged, wherein the host warning module generates a warning signal when the distance between the paired sensor and host exceeds a predetermined warning distance, and the operation module can perform operations of pairing between the host and the sensor and setting the warning distance in conjunction with the display module. |
