Be it is multiple, i.e., ultrasonic receiver 221 will send the range information after primary first time, this implementation at regular intervals
Example sent primary every 5 seconds.
Later, controller 3 according to the first time range information got calculate for the first time wearable sensing apparatus 21 away from
Height from the ground, specifically, the line between two signal receiving modules 22 is vertical when signal receiving module 22 is two
Or be parallel to ground setting, by taking line is perpendicular to ground as an example, height of two signal receiving modules 22 apart from ground it is known that and
The distance between two signal receiving modules 22 and the signal emission module 212 of wearable sensing apparatus 21 are also measured, at this time
Two signal receiving modules 22 and signal emission module 212 are in one perpendicular in the plane on ground, and two signals receive
Module 22 and signal emission module 212 collectively form a triangle, the height by two signal receiving modules 22 apart from ground
Degree and the distance between two signal receiving modules 22 and signal emission module 212, can be by 212 distance of signal emission module

Then controller 3 calculates the wearable sense after first time according to the range information after the first time got
Answer equipment 21 apart from the height on ground, Computing Principle and for the first time calculating of height of the wearable sensing apparatus 21 apart from ground
Principle is identical.
Later, the height according to the wearable sensing apparatus 21 for the first time apart from ground and after first time described in wear
The difference for wearing height of the formula sensing apparatus 21 apart from ground judges whether user falls down, i.e., when the wearable induction described for the first time is set
The difference of standby 21 height apart from ground and height of the wearable sensing apparatus 1 apart from ground after first time is greater than pre-
If when difference, that is, can determine whether that user falls down.Such as when the normal bathing of user, the first time measured the wearable sensing apparatus 21
Height apart from ground is L1, and the wearable sensing apparatus 21 after then carrying out primary first time every 5 seconds is apart from ground
Height of the wearable sensing apparatus 1 apart from ground after first time is set L2 by the detection of the height in face, then counts
The difference for calculating L1 and L2, when user falls down, difference between L1 and L2 can be greater than preset difference value, when controller 3 twice in succession
When measuring the difference between L1 and L2 above greater than preset difference value, that is, it can determine whether that user falls down.In the present embodiment, above-mentioned default difference
Value can be set to 0.5 meter.

The judgement whether user falls down is carried out, specifically, when controller 3 is judged by the first detection device 1 and second detection device 2
When user does not fall down, user is in normal condition.
When controller 3 judges that user falls down by the first detection device 1 and second detection device 2, at this time due to two
A detection device provides identical as a result, then illustrating that user falls down really, and judging result is more accurate, reduces exclusive use
False Rate when one of detection device is detected, controller 3 controls alarm module alarm at this time, and user relatives is prompted to use
It falls down at family.
When controller 3 is judged as use by one of detection device in the first detection device 1 and second detection device 2
Family is fallen down, and when another detection device is judged as that user does not fall down, alarm module is not alarmed directly, above-mentioned first detection device 1
Continue to detect with second detection device 2, when detection is multiple, if controller 3 passes through the first detection device 1 and the second detection
Judging result after device 2 is detected is identical, and controller 3 then carries out corresponding operation according to judging result, if remained
One of detection device is judged as that user falls down, and when another detection device is judged as that user does not fall down, controller 3 is then direct
Alarm module and alarm are controlled, is confirmed by user relatives.
