Problems solved by technology

[0003] (1) There is a lack of a mobile phone pedometer algorithm that only collects single-sensor data, has high accuracy, and takes into account high precision and low energy consumption;
[0004] (2) It is impossible to judge whether the user is currently using the mobile phone based on the change of the number of steps, and other conditions need to be combined;
[0005] (3) There is a lack of a step-by-step walking safety warning mechanism, and the safety protection technology for mobile phone "head-down people" is basically in a blank state;
[0006] (4) When a mobile phone user has a fall accident, there is a lack of an effective fall detection and rescue mechanism

Embodiment

[0066] This embodiment contains two modules.

[0067] Module 1 is responsible for real-time monitoring of whether the mobile phone user is currently in the walking state of "head bowing". That is to monitor in real time whether the mobile phone user is currently in walking mode, and at the same time monitor whether the front-facing face can be detected in the photos taken by the front camera of the mobile phone held by the user, and issue a safety warning to the "head-lowering group".

[0068] Module 2 is responsible for monitoring sudden changes in the user's motion state. When the current motion characteristics of the mobile phone user conform to the fall mode, it will send a distress inquiry to the user. If the user does not manually cancel within 5 seconds, it will be judged that the user has fallen, and the mobile phone will send out a distress ringtone, and send a pre-set mobile phone number / WeChat Send a distress message containing the user's current geographic locatio...

Abstract

The invention discloses a walking safety alarm method for people with bowed heads, which includes the following steps: step 1, determine whether the user is in a walking state, if so, perform step 2, otherwise determine that the user is in a safe state; step 2, detect whether the user is using a mobile phone , if yes, determine that the user is using the mobile phone while walking, go to step 3, otherwise go to step 1; step 3, send an alarm to the user.

Description

technical field [0001] The invention relates to a walking safety alarm method for people with bowed heads. Background technique [0002] With the rapid development of smart phones and mobile technology, mobile phones have become an indispensable portable device in people's lives. In recent years, it is not uncommon for users to lower their heads and use their mobile phones without paying attention to road traffic conditions, resulting in life-threatening cases. In view of this, a software that can run on smart phones and can warn users of walking safety is very urgent. The deficiencies of the prior art are: [0003] (1) There is a lack of a mobile phone pedometer algorithm that only collects single-sensor data, has high accuracy, and takes into account high precision and low energy consumption; [0004] (2) It is impossible to judge whether the user is currently using the mobile phone based on the change of the number of steps, and other conditions need to be combined; ...
