Embodiment

[0047] The system proposed by the present invention is constructed according to the above method. The device uses the three-axis acceleration sensor MMA7260Q of Feike Company, the two-axis angular velocity sensor IDG-300 of InvenSense Company, the processor STM32 of ST Company (including on-chip A / D), and the nRF905 wireless module of NORDIC. Its circuit connection diagram is as follows: Figure 5 Shown: The x-axis acceleration signal (pin 15) output by the acceleration sensor passes through a passive RC low-pass filter and then connected to the microcontroller PC0 pin (pin 15), which is an on-chip high-speed digital-analog The analog channel 10 of the converter; the output of the y-axis acceleration signal and the z-axis acceleration signal (the 14th and 13th pins) are respectively connected to PC1 and PC2 (the 16th and 17th pins) after passing through the low-pass filter, which The two are channel 11 and channel 12 of the on-chip digital-to-analog converter. In addition, t...

Abstract

The invention relates to an automatic detection alarming system for falling over of human body and an information processing method thereof; the system is composed of a wearable detection device and a base station; the wearable detection device comprises a three-axis acceleration sensor, a two-axis angular rate sensor, an A/D, an information processing device and a wireless signal emission device; the base station comprises a signal receiving device and an alarming device; the wearable detection device is wore on the trunk part of the human body, the relative kinesiology and kinetics information is collected and is fused, so as to judge whether human body activity has falling over action; if a wearer falls over and needs to be helped, the falling-over information is transmitted to the base station, and the base station transmits a message for help to relevant departments or related personnel after receiving a wireless signal. The automatic detection alarming system has the characteristics of high detectable rate and low false rate, so as to judge the falling over of the human body and provide rescue for the old, patients, dangerous operating personnel who fall over.

Description

Technical field: [0001] The invention relates to a detection and alarm system and an information processing method for monitoring and identifying human body movement behaviors and states, and in particular to an automatic detection and alarm system for human body falls and an information processing method. Background technique: [0002] According to the statistics of the World Organization for Disease Control and Prevention, one-third of the elderly over 65 years old in the world will fall every year, half of which will be recurrent falls, and nearly 10% of one-time falls will cause serious injuries or serious injuries. disease; resulting in a huge medical burden and health damage. For example: in the United States, the diseases directly caused by falls account for 6% of the total medical expenditure; in 2002, a total of 19 billion US dollars was spent, and 15-20% of the elderly who fell died within a year due to diseases directly or indirectly caused by falls; According to ...
