Auto-dialing distress method used after user falling detected by smart phone

Abstract

The invention discloses an auto-dialing distress method used after user falling detected by a smart phone. The auto-dialing distress method includes the steps that 1, the smart phone samples the accelerations and calculates a resultant acceleration a; 2, the resultant acceleration a is judged whether or not to be larger than an acceleration threshold value T1, if so, go to the step 3; if not, back to the step 1; 3, three axis attitude angles of the smart phone are calculated, and two of the three-axis attitude angles are judged whether or not to be larger than an angle threshold value T2, if so, go to the step 4; if not; back to the step 1; 4, the smart phone prompts an alarm, and a timer starts, if the alarm is manually released within 10s, back to the step 1; or not, go to the step 5; 5, a preset number is automatically dialed, and a short message showing the position of the smart phone is sent.

Description

technical field [0001] The invention relates to the technical field of digital electronic information, in particular to a smart phone fall detection and automatic dialing for help method for pregnant women and elderly people to detect falls and automatically dial for help. Background technique [0002] At present, in China, the trend of aging is becoming more and more serious, and pregnant women also account for a considerable proportion of the population. These people are prone to accidents such as falls due to physical inconvenience. If they are not treated in time, it is likely to cause serious consequences. Therefore, methods and devices for fall detection and help seeking for pregnant women and elderly people are necessary. The existing fall detection method is based on video monitoring, and some abnormal movements of the human body are monitored by video to provide fall warning. However, the video-based method can only be used in a specific regional environment, and t...

Problems solved by technology

[0004] Aiming at the problem that the video monitoring is limited by the environment and the accuracy of the existing accelerometer to judge the fall is not high, the present invention proposes a smart phone fall detection automatic dialing for help method that uses the combination of the accelerometer and the gyroscope in the smart phone to detect the fall
