Embodiment 1

[0038] Such as figure 1 As shown, a concealed radar fall alarm method includes the following functional modules:

[0039] The radar signal detection module 1 is used to transmit radar signals, and record the action status information of the monitored person through real-time monitoring of the received radar signals;

[0040] The signal processing and analysis module 2 processes and analyzes the above-mentioned signals, and makes a fall judgment;

[0041] The communication module 3 transmits the above-mentioned information data and judgment results to the server 5;

[0042] The power supply module 4 is used to supply power to the above-mentioned modules;

[0043] Server 5, for storing the data information of the monitored person;

[0044] The client 6 is used to receive the information from the server 5 and feed it back to the guardian.

[0045] This embodiment also includes an alarm 7, which is directly connected to the communication module 3 to obtain an alarm signal.

Embodiment 2

[0050] A monitoring method based on embodiment one concealed radar fall alarm method, comprising the following steps:

[0051] 1) The radar signal detection module 1 transmits and receives radar signals, and records the position of the monitored person through real-time monitoring of the received radar signals;

[0052] 2) The signal processing analysis module 2 shields the background signal and interference signal through the filter, and amplifies the effective signal through the amplifier, and when it is detected that the position of the human head is from above the ground to the ground and the falling speed is 0.01m When / s—13m / s, it is judged as a fall; the position change value judgment is as follows: when standing, the distance between the head position and the radar detection device is about 0-22m; when falling to the ground, the distance between the head position and the radar signal detection module is less than 25m.

[0053] 3) The communication module 3 transmits th...

Embodiment 3

[0070] Such as figure 1 As shown, a concealed radar fall alarm method includes a signal module, a server 5 and a client 6 . The signal module includes a radar signal detection module 1 , a signal processing and analysis module 2 , a communication module 3 and a power supply module 4 . The client 6 includes a client 6 and an alarm 7 . The radar signal detection module 1 transmits and receives radar signals, and the signal processing and analysis module 2 processes and analyzes the received radar signals to determine whether a fall occurs. The communication module 3 transmits the processed data and analysis results to the server 5, and these data can be stored in the server 5 for a long time. The client 6 displays the alarm information through the mobile phone APP. Among them, the radar signal detection module 1 is connected with the signal processing unit, the signal processing and analysis module 2 is connected with the communication module 3 , the power supply module 4 is ...

Abstract

The invention relates to a hidden radar falling alarming method applicable to supervision and care of people who easily fall and applies to the technical field of medical care instruments. The methodcomprises steps as follows: a radar signal detection module transmits and receives a radar signal, and a signal processing and analysis module processes and analyzes the received radar signal and judges whether a falling phenomenon happens. A communication module transmits processed data and analysis results to a server, and these data can be stored in the server for a longer time. A client displays alarming information through a mobile phone APP, so that a guardian conveniently handle the falling condition, the guardian is not required to accompany a person at any moment, and the working intensity of the guardian is reduced.

Description

technical field [0001] The invention relates to a concealed radar fall alarm method, which is suitable for the supervision and care of people who are prone to falls, and is applied in the technical field of medical care equipment. Background technique [0002] First of all, we need to understand that a fall refers to a sudden, involuntary, and unintentional change in position, such as falling on the ground or a lower surface. Falls are a major cause of accidental injury and death in the world, especially threatening the lives of the elderly Therefore, it is very important to monitor whether the elderly have fallen and to report to the police after the fall. [0003] There are some devices that can detect falls on the market at present, such as Chinese Patent Publication No. "206133864U" discloses a "fall alarm 7, including a housing, a mounting belt, a main control chip, a detection system and an alarm system, the top of the housing There are installation slots on the surfa...
