Abstract

The invention discloses an anti-lost early warning method and an anti-lost early warning system. The method comprises the following steps that a first mobile terminal establishes near field wireless communication connection with wearable equipment; and when the first mobile terminal is disconnected with the wearable device, other mobile terminals in the communication module perform scanning, and when the first mobile terminal and the wearable device are not scanned, other electronic devices perform scanning, and when the first mobile terminal or the wearable device is scanned and connection is established, the other electronic devices perform scanning; the positions of the other electronic devices are sent to other mobile terminals through the server, and the other mobile terminals are triggered to give an alarm. When other mobile terminals determine that the distance between the first mobile terminal and the wearable device is not within the near field communication range, other electronic devices search for the first mobile terminal and the wearable device at the same time, the search range is expanded, and the user experience is improved under the condition that the user does not know that the first mobile terminal or the wearable device is lost; the positions of the first mobile terminal and the wearable device can be tracked in time.

Description

technical field [0001] The invention relates to the technical field of smart devices, in particular to an anti-lost early warning method and system. Background technique [0002] Existing products tend to be miniaturized, such as mobile phones, tablet computers, smart watches, and wearable devices. These products are easy to forget or lose, and it takes time and effort to find them, causing great inconvenience. In the prior art, the Bluetooth device is set on the wearable item. When the wearable item is separated from the mobile terminal by a certain distance, the mobile terminal will give an alarm, or when the mobile terminal is separated from the wearable item by a certain distance, the wearable item will alarm. Alarming, currently, the mobile terminal is basically monitored through the wearable item or the wearable item is monitored through the mobile terminal, and when the mobile terminal or the wearable item is known to be lost, it is tracked through another device, whi...
