[0019] Such as figure 1 As shown, the mobile terminal of this embodiment includes a control module 1 , an ultrasonic sensor 2 , a computing module 3 , a display screen 4 and a speaker 5 .

[0020] The mobile terminal further includes a main board, and the ultrasonic sensor 2 is connected to the main board. In this embodiment, the ultrasonic sensor 2 is embedded in the housing of the mobile terminal, which can be used in the mobile terminal on the back of the mobile terminal, or on the side of the mobile terminal.

[0021] Wherein the control module 1 controls the start and stop of the ultrasonic sensor 2, and the control module 1 can be used to start the ultrasonic sensor 2 when the user is walking and playing with the mobile phone while bowing his head. After the ultrasonic sensor 2 is started, the ultrasonic sensor 2 sends an ultrasonic signal. Since the ultrasonic wave has a strong directivity, the propagation distance in the medium is relatively long, so it can be used to...

[0030] Such as image 3 As shown, the mobile terminal of this embodiment includes a control module 1 , three ultrasonic sensors 2 , a computing module 3 , a display screen 4 and a speaker 5 .

[0031] The difference between this embodiment and the first embodiment is that the mobile terminal of this embodiment includes three ultrasonic sensors 2. Since the directivity of ultrasonic waves is very strong, the range of detecting obstacles in this embodiment is wider than that of the first embodiment. wider and higher precision.

[0032] In addition, the ultrasonic signals sent by each of the ultrasonic sensors 2 can be marked with the identity information of the ultrasonic sensors 2, for example, the three ultrasonic sensors 2 can respectively send three kinds of ultrasonic signals with different frequencies such as A 1 、A 2 、A 3 , in this case, the calculation module 3 can easily distinguish the ultrasonic signals A of the three ultrasonic sensors 2 according to the frequency...

Abstract

The invention discloses a mobile terminal and a barrier alarm method. The mobile terminal comprises at least a supersonic sensor, a calculating module and a control module. The supersonic sensor is embedded in a housing of the mobile terminal and is connected with a mainboard. The supersonic sensor sends a supersonic wave signal to a barrier and receives the supersonic wave signal reflected from the barrier. Based on a time interval between sending the supersonic wave signal and receiving the supersonic wave signal by the supersonic sensor, the calculating module calculates a distance between the supersonic sensor and the barrier. The control module controls starting and shutdown of the supersonic sensor, and controls a display screen or a loudspeaker to give an alarm when the distance is less than a threshold. According to the barrier alarm method which is realized by utilizing the mobile terminal, the distance between the barrier and a user can be calculated, when the distance is less than the threshold, the alarm is given, thus the user is prompted to pay attention to the barrier so as to avoid collision with the barrier, and the security of the user is protected.

Description

technical field [0001] The present invention relates to an obstacle alarm method, in particular to a mobile terminal equipped with an ultrasonic sensor capable of calculating the distance between the obstacle and the ultrasonic sensor, and an obstacle alarm method realized by the mobile terminal. Background technique [0002] With the advancement of society and technology, people's demand for mobile terminals such as mobile phones is increasing day by day. While mobile phones bring convenience to people, they also bring some potential safety hazards. Many people lower their heads and play with their mobile phones while walking, such as sending text messages, playing games, surfing the Internet, etc., thus often ignoring the obstacles or dangers that may be encountered ahead, which will cause many collision accidents and endanger people's health. And the more bustling streets, the more the risk of collision accidents, therefore, there is an urgent need for a mobile phone that...
