As shown in FIG. 1, the anti-drop method according to an embodiment of the present disclosure may include steps S101 to S103.

In step S101, the monitor device broadcasts the first WiFi-Aware broadcast.

In step S102, the monitoring target device broadcasts the second WiFi-Aware broadcast after receiving the first WiFi-Aware broadcast.

In step S103, if the monitor device receives the second WiFi-Aware broadcast, it is determined that the monitoring target device is within the security range of the monitor device, otherwise it is determined that the monitoring target device is in the lost state.

In the embodiment of the present disclosure, the monitor device corresponds to the monitor device carried by the monitor. The monitoring target device corresponds to the monitoring target device carried by the monitoring object.

According to the embodiment of the present disclosure, it is possible to effectively prevent the monitoring object corresponding to the monitoring target device from being outside the complete range of the monitoring device, that is, the monitoring object can be effectively prevented from being lost. The anti-drop method according to an embodiment of the present disclosure may be implemented without a GPS and a mobile network, and further, the monitor device and the monitoring target device do not need to be connected via a wireless connection. The anti-drop method according to an embodiment of the present disclosure is low in power consumption when implemented.

According to an embodiment of the present disclosure, it is possible to monitor in real time whether the object is within a safe range, rather than recovering it after being lost. The monitoring target device may be one or more than one. For example, the tour guide carries the monitor device, and the visitor carries the monitoring target device, and the anti-drop method according to the embodiment of the present disclosure can effectively prevent the loss of the visitor. For another example, the parent carries the monitor device, the child carries the monitoring target device, and the anti-drop method according to the embodiment of the present disclosure can effectively prevent the child from being lost.

Player, PMP), navigation device, wearable device, smart bracelet, pedometer, etc.

According to an embodiment of the present disclosure, the first WiFi-Aware broadcast may carry device identification information of the monitoring target device. Thereby, the monitoring target device can know that the first WiFi-Aware broadcast it receives is broadcasted by the monitor device.

According to an embodiment of the present disclosure, the monitor device may receive the third WiFi-Aware broadcast and parse the device identification information from the third WiFi-Aware broadcast. If the parsed device identification information is consistent with the pre-stored device identification information of the monitoring target device, it is determined that the third WiFi-Aware broadcast received by the monitor device is the second WiFi-Aware broadcast broadcast by the monitoring target device.

The step of parsing the device identification information from the third WiFi-Aware broadcast may include: parsing the broadcast type from the third WiFi-Aware broadcast; and parsing the device identification information from the third WiFi-Aware broadcast if the broadcast type is the tracking type .

According to an embodiment of the present disclosure, the monitor device may broadcast the first WiFi-Aware broadcast according to a preset frequency, and after receiving the first WiFi-Aware broadcast, the monitoring target device may broadcast the second WiFi-Aware broadcast according to the frequency. .

The monitor device and the monitoring target device broadcast the WiFi-Aware broadcast to each other according to the unified frequency. Only when both parties receive the WiFi-Aware broadcast sent by the other party, it is confirmed that the monitoring object is within the security range of the monitor, otherwise the monitoring object is in the same state. Lost state.

After the WiFi-Aware function is enabled, the smart terminal with the WiFi-Aware function broadcasts to the surrounding area. The coverage of the broadcast is the security range of the anti-drop, and the monitoring object that is not in the safe range is in the lost state. If the monitored object is in the security range and receives the WiFi-Aware broadcast sent by the smart terminal, the monitoring object needs to be fed back through the WiFi-Aware broadcast. Otherwise, the intelligent terminal determines that the monitored object is in the lost state.
