specific Embodiment 1

[0050] like figure 1 As shown, an intelligent monitoring method for falling of an elderly person comprises the following steps:

[0051] Step 1, using the radar to collect the human body posture echo data of the target in real time, and processing the human body posture echo data to obtain the time-frequency analysis result; wherein, the time-frequency analysis result includes a distance-time diagram and a Doppler-time diagram, That is, it contains the position information and Doppler information of the target;

[0052] An X-Y coordinate system is established with a fixed position as the origin. The radar includes radar A at the origin, radar B on the X axis, and radar C on the Y axis. Radar B and radar C move at a fixed interval along the coordinate axis Scan and collect at different locations; the fixed location is, for example, the top of the corner of the room, such as figure 2 As shown, the specific steps of using the radar to collect the target's human posture echo da...

specific Embodiment 2

[0081] like image 3 As shown, an intelligent monitoring system for elderly falls includes a data collection terminal 1, a data processing terminal 2 and a display terminal 3; wherein, the data collection terminal 1 includes one or more human body posture collection and processing modules 11 and carrier components 12; The attitude acquisition processing module 11 comprises a human body attitude acquisition unit 111, a micro-processing unit 112 and a wireless communication unit W113, and the human body attitude acquisition unit 111 is used to collect human body attitude echo data in different orientations, and transmits to the micro-processing unit 112; the micro-processing unit 112 is used to process the human body posture echo data, and transmit the time-frequency analysis result obtained after processing to the data processing terminal 2 through the wireless communication unit W113; the carrier part 12 is used to carry the human body posture acquisition and processing module ...

Abstract

An intelligent monitoring method and system for falls of the elderly belongs to the field of intelligent monitoring, and is used to solve the problem that the radar detection range of a single fixed position in the existing fall monitoring equipment is limited by the beam angle and human body occlusion affects behavior recognition. The present invention utilizes the millimeter-wave radar of multi-point moving arrangement to collect the characteristic data of the human body posture from different directions to form a three-dimensional detection, which solves the problem that the detection range of the radar module at a single fixed position is limited by the beam angle; Time-frequency analysis results are analyzed and judged to determine whether the target has fallen behavior, which solves the problem that the accuracy of behavior recognition is affected by human body occlusion in the existing fall monitoring method, and greatly improves the accuracy and stability of behavior recognition results It realizes the recognition of behaviors and postures of the elderly such as walking, standing, and falling, and has important medical and social values.

Description

technical field [0001] The invention relates to the field of intelligent monitoring, in particular to an intelligent monitoring method and system for falling of the elderly. Background technique [0002] Under the background of population aging, patient care has brought great difficulties to families and hospitals; especially during the epidemic period, there was a shortage of medical staff, and patient care encountered great challenges. In daily life, falls and falls during walking can easily cause physiological and psychological problems for the elderly. However, traditional fall monitoring equipment has problems such as poor privacy protection, restricting the activities of the elderly, and being susceptible to electromagnetic interference. It is difficult to use them in hospitals or nursing homes. The place is popular. The 77GHz millimeter-wave radar has millimeter-level high resolution and can detect the patient's position through the curtain. The received data include...
