Abstract

The invention discloses an alarming method and system against straying based on the WIFI direct connection technology. The method comprises that a monitored device establishes a WIFI direct connection group in advance; a monitor joins the WIFI direct connection group and is connected with the monitored device, and a monitoring group is established; the monitor detects the intensity value of communication signals between the monitor and the monitored device in real time; when the intensity value, detected by the monitor, of the communication signals is lower than a preset signal intensity threshold, the monitor transmits a request for reporting self position to the monitored device; and the monitored device raises the alarm when receiving the request. According to the method and system, a local area network is established between a monitoring person and a monitored person, monitoring is not influenced by the environmental network, when the monitored person is far from the monitoring person, the monitoring person can receive the alarm while the device of the monitored person is triggered to emit alarming sound, and thus, kids and the elder are effectively prevented from straying.
