Abstract

The present invention provides a mobile terminal, and a mobile terminal risk monitoring method and device. The device comprises: a signals transmit-receive module configured to emit detection signals with first frequency and receive echo signals with second frequency through reflection of the detection signals by a monitored object; a distance analysis module configured to obtain a distance between the monitoring object and a mobile terminal according to the time difference between transmission of the detection signals and receiving of the echo signals; a speed analysis module configured to obtain the relative speed between the monitoring object and the mobile terminal according to the frequency shift of the second frequency relative to the first frequency; and a risk alarm module configured to determine whether risk alarm is needed or not according to the distance between the monitoring object and the mobile terminal and the relative speed. The present invention can better realize risk early warning.

Description

technical field [0001] The present disclosure relates to the technical field of mobile terminals, and in particular, to a mobile terminal risk monitoring device, a mobile terminal risk monitoring method, and a mobile terminal using the mobile terminal risk monitoring device. Background technique [0002] With the rapid development of computer technology and mobile Internet technology, mobile terminals represented by smart phones and tablet computers have become increasingly popular. These mobile terminals bring great convenience to people's life with the characteristics of simple operation, portability, and rich functions, but at the same time, people's dependence on mobile terminals is gradually increasing. [0003] Due to the dependence on the mobile terminal, many people put their attention on the mobile terminal, which also brings a lot of troubles to people. For example, some people watch videos, send text messages, take pictures, and play games through mobile terminal...
