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.
监控者设备和监控对象设备可以是具有WiFi-Aware功能的移动终端，例如，手机、平板电脑、笔记本电脑、掌上电脑、个人数字助理(Personal Digital Assistant，PDA)、便捷式媒体播放器(Portable Media Player，PMP)、导航装置、可穿戴设备、智能手环、计步器等。The monitor device and the monitoring target device may be WiFi-Aware-enabled mobile terminals, such as mobile phones, tablets, notebook computers, PDAs, personal digital assistants (PDAs), and portable media players (Portable Media).

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.
具有WiFi-Aware功能的智能终端在开启WiFi-Aware后向周围广播，其广播的覆盖范围就是防跟丢的安全范围，不在安全范围内的监控对象处于跟丢状态。如果监控对象在安全范围内，并接收到智能终端发出的WiFi-Aware广播，则需要监控对象通过WiFi-Aware广播的方式进行反馈，否则智能终端会判定监控对象处于跟丢状态。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.
监控对象可以是多个，并且可以通过列表的形式展示其实时的状态。此外，监控对象也可以反过来也监控的智能终端，在权限许可的情况下，可以实现双向防跟丢。The monitoring object can be multiple and can display its real-time status in the form of a list.

在步骤S203，监控对象设备接收到监控者设备发送的广播，并反馈广播。In step S203, the monitoring target device receives the broadcast transmitted by the monitor device and feeds back the broadcast.
在步骤S204，监控者设备收到反馈并判断监控对象设备在安全范围内，进而返回步骤S202。In step S204, the monitor device receives the feedback and determines that the monitoring target device is within the safe range, and returns to step S202.
在步骤S205，监控者设备未收到反馈并判断监控对象设备处于跟丢状态。In step S205, the monitor device does not receive the feedback and determines that the monitoring target device is in the lost state.
在步骤S206，监控者设备向监控者发出提示，并显示控对象设备处于跟丢状态，进而返回步骤S202。In step S206, the monitor device issues a prompt to the monitor, and displays that the control target device is in the lost state, and returns to step S202.
基于上述流程，根据本实施例的防跟丢方法实际上是一个不断循环的检测的方法，并且在跟丢的情况下提示监控者，监控对象设备处于跟丢状态，需要及时与监控对象联络，使其重新进入安全范围。此外，如果处于跟丢状态的监控对象设备重新进入安全范围之内，则可以通知监控者，该监控对象设备已脱离跟丢状态回到安全范围内。Based on the foregoing process, the anti-drop method according to the embodiment is actually a method for continuously detecting the loop, and prompts the monitor in the case of losing, and the monitoring target device is in the state of losing, and needs to contact the monitored object in time. Bring it back into safe range. In addition, if the monitoring target device in the lost state re-enters the security scope, the monitor can be notified that the monitored target device has left the lost state and returned to the safe range.
