specific Embodiment approach 1

[0030] Specific implementation mode one: combine figure 1 This embodiment will be described. The composite sensor-based intelligent monitoring system for preventing falls for the elderly given in this embodiment includes:

[0031] Human body acceleration data acquisition assembly 1, micro-processing module 2, alarm module 3, wireless communication assembly 4 and power supply module 5 (as attached figure 1 shown); the human body acceleration data acquisition assembly 1, the microprocessing module 2, the alarm module 3 and the wireless communication assembly 4 are all arranged on the PCB board (Printed Circuit Board printed circuit board); in the present embodiment, the microprocessing module adopts Hongjing Technology STC15F104E;

[0032] The human body acceleration data acquisition assembly 1 includes three Hall acceleration sensors and a three-axis acceleration sensor, and the three Hall acceleration sensors and the three-axis acceleration sensor collect the human body accel...

specific Embodiment approach 2

[0036] Specific implementation mode two: as figure 2 As shown, the difference between this embodiment and the first embodiment is that the three Hall acceleration sensors are respectively arranged along the X, Y, and Z three-axis directions in space, and are used to collect the accelerations of the X, Y, and Z axes in real time. Data; the Z-axis direction is the vertical direction when the human body normally stands, the Y-axis direction is the front-to-back direction when the human body normally stands, and the X-axis direction is the left-right direction when the human body normally stands, O S is the origin of the coordinates.

[0037] Other steps and parameters are the same as those in the first embodiment.

specific Embodiment approach 3

[0038] Embodiment 3: This embodiment is different from Embodiment 1 in that the alarm module 3 includes LED lights and speakers, and the alarm module 3 is also provided with buttons for controlling the LED lights and speakers. When the MCU micro-processing module 2 judges that a fall occurs, an instruction is sent to the alarm module 3, and the LED lights of the alarm module 3 flash continuously and emit a buzzer sound.

[0039] Other steps and parameters are the same as those in Embodiment 1 or 2.

Abstract

The invention provides an anti-falling intelligent monitoring system and method for old people based on a composite sensor, and belongs to the technical field of intelligent monitoring. Three Hall acceleration sensors and a three-axis acceleration sensor respectively and independently acquire human body acceleration data in real time and transmit the human body acceleration data to a micro-processing module through an OR gate; the micro-processing module receives the data and performs data processing by utilizing a deep learning algorithm to judge whether a user falls down; when the user is judged to fall down, alarm information is transmitted to an alarm module; information fed back by the alarm module is received at the same time; if the micro-processing module does not receive the information that a button on the alarm module is closed within a preset time, a distress instruction is transmitted to a wireless communication assembly; and the wireless communication assembly transmits the distress signal and positioning information to a preset device after receiving the distress instruction transmitted by the micro-processing module. The system solves the problems of weak anti-interference capability and instability of a prior anti-falling monitoring technology for old people. The system can be used for human body fall monitoring.

Description

technical field [0001] The invention relates to an intelligent monitoring system and a monitoring method for preventing falls of the elderly, and belongs to the technical field of intelligent monitoring. Background technique [0002] In the modern aging society, the issue of guardianship for the elderly has attracted much attention. The functions of the elderly are deteriorating in all aspects, and they need someone to monitor them at any time to avoid some unexpected situations. The occurrence of falls is the most common and unpredictable behavior of empty nesters, which can lead to serious injuries and even life-threatening behaviors. For the fall monitoring problem of the elderly, many scholars have proposed relevant solutions; for example, Sun Xinxiang of Shanghai Jiaotong University uses a three-axis acceleration sensor to collect the three-dimensional acceleration value of the human body, and performs spatial positioning after the abnormal data appears, and finally wil...
