Embodiment 1

[0047] figure 1 The implementation process of the method for detecting whether the surrounding environment is safe according to the first embodiment of the present invention is shown, and the details are as follows:

[0048] In step S101, the WiFi reference signal of the environment and the wave source orientation of the WiFi reference signal are determined.

[0049] In the embodiment of the present invention, the wearable device first controls the first antenna and the second antenna to receive the first WiFi signal and the second WiFi signal of the environment, and then compares the first WiFi signal and the second WiFi signal , Lock the WiFi signal with the highest signal strength as the WiFi reference signal, and then control the wearable device to move in different directions, and determine the direction where the strength of the WiFi reference signal increases fastest as the wave source azimuth.

[0050] Among them, the wearable device can be a smart watch, such as figure 2 As...

Abstract

The invention belongs to the technical field of communication and provides a method and device for detecting whether surroundings are safe or not and a wearable device. The method comprises the steps of determining a WiFi reference signal of the environment and a wave source direction of the WiFi reference signal; receiving the WiFi reference signal and a reflection signal, wherein the reflection signal is a wireless signal reflected by surrounding objects; comparing the WiFi reference signal with the reflection signal, and determining the moving direction of the surrounding objects according to frequency changes of the reflection signal and the wave source direction; displaying the moving direction and / or a prebound mobile terminal sending the moving direction. According to the method and device, the protection effect on a wear wearing the wearable device is achieved, the purpose of taking care of the old or the children is achieved, and the purpose of detecting the safety of the surroundings through the wearable device is achieved.

Description

Technical field [0001] The invention belongs to the field of communication technology, and in particular relates to a method, a device and a wearable device for detecting whether the surrounding environment is safe. Background technique [0002] Wearable devices are the general term for using wearable technology to intelligently design everyday wear and develop wearable devices, such as glasses, gloves, watches, clothing and shoes. [0003] Wearable devices can provide exclusive and personalized services for everyone, and its appearance will change the lifestyle of modern people. [0004] However, in the process of implementing the present invention, the inventor found that the wearable device provided by the prior art has at least the following problems: [0005] At present, wearable devices, such as watches, monitor children or the elderly mainly through positioning and talking. At the same time, they have a one-key call for help function, but they cannot detect the safety of the su...
