Embodiment Construction

[0030] The present invention will be further elaborated below by describing a preferred specific embodiment in detail in conjunction with the accompanying drawings.

[0031] Such as figure 2 As shown, the fall detection system based on the mobile terminal includes: CPU 10, and a three-axis acceleration sensor 20 connected thereto, a gyroscope sensor 30, a distance sensor 40, a magnetic sensor 50, a GPS module 60, a speaker 70 and a mobile terminal touch display 80 . The CPU 10 performs two-way communication with the above modules respectively. The detection system is built into the smart mobile terminal.

[0032] In real life, people generally place their mobile phones in the pockets on both sides of their trousers or coat, close to their waists, which can well reflect the movement state of the human body. The default position of the mobile phone in the present invention is placed at this position.

[0033] There are four common ways for the human body to fall, which are f...

Abstract

The invention discloses a mobile terminal based tumble detecting method. The mobile terminal based tumble detecting method comprises the steps as follows: detecting a total accelerated velocity SVM1 and judging whether the total accelerated velocity SVM1 exceeds a set weightlessness threshold Amin; when SVM1 is smaller than Amin, detecting and synthesizing a direction signal omega1 and judging whether the direction signal omega1 exceeds a set inclination angle threshold omegamin; when the omega1 is smaller than the omegamin, detecting a total angular velocity omega and judging whether the total angular velocity omega exceeds a set angular velocity threshold omegamin; when the omega is greater than the omegamin, detecting a total accelerated velocity SVM2; when the total accelerated velocity SVM2 is greater than a set impact acceleration threshold Amax within a set detecting time t1, detecting and synthesizing a direction signal omega2 and judging whether the direction signal omega2 exceeds a set human body tumble gradient threshold omegamax; when the omega2 is less than the omegamax, indicating that the person has tumbled; processing a signal judging that the person has tumbled into a voice prompt signal and an image display signal. By referring to the feature acceleration, the human body inclination state, the angular velocity and the like in the tumble process of the human body and using a built-in sensor in a mobile phone to obtain necessary parameters, the mobile terminal based tumble detecting method can analyze and judge whether the person tumbles.

Description

technical field [0001] The invention relates to the identification of human body fall conditions, in particular to a fall detection method based on a mobile terminal. Background technique [0002] With the gradual increase of my country's population aging, there are more and more empty-nesters in society. And the old people's physique is weaker, often can accidentally fall, and fall itself has caused great harm to the old people, and not timely rescue can bring fatal danger to the old people more. Therefore, various methods of effectively identifying human body falls and reporting to the police in time are of great significance to society. These include: based on video analysis technology, real-time monitoring and analysis of the human body to determine whether the human body has fallen; based on audio signal analysis technology, the fall status is judged by analyzing the frequency when the person hits the ground and other judgment methods. [0003] As smartphones have bec...
