Afterwards, 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, when signal receiving module 22 is two, the line between two signal receiving modules 22 is vertical
Or parallel to ground set, so that line is perpendicular to ground as an example, two signal receiving modules 22 apart from ground height, it is known that and
The distance between two signal receiving modules 22 and signal emission module 212 of wearable sensing apparatus 21 are also measured, now
Two signal receiving modules 22 are in one in the plane on ground with signal emission module 212, and two signals receive
Module 22 collectively forms a triangle with signal emission module 212, the height by two signal receiving modules 22 apart from ground
The distance between degree and two signal receiving modules 22 and signal emission module 212, can be by the distance of signal emission module 212
The height on ground is calculated.
When signal receiving module 22 is two or more, using the position of signal receiving module 22 as the center of circle, received with signal
The distance between module 22 and signal emission module 212 are that radius constructs a circle, because signal receiving module 22 is two
Above and it is all disposed within wall, therefore more than at least three circle can be constructed, now the intersection point of the circle of more than three is only
One (i.e. the position of the present embodiment signal emission module 212), therefore the height of signal emission module 212 can be calculated.
Then controller 3 calculates the wearable sense after first time according to the range information after the first time got
Answering equipment 21, its Computing Principle is with wearable sensing apparatus 21 for the first time apart from the calculating of the height on ground apart from the height on ground
Principle is identical.
Afterwards, worn according to the wearable sensing apparatus 21 for the first time apart from the height on ground and described in after first time
Wear formula sensing apparatus 21 and judge whether user falls down apart from the difference of the height on ground, i.e., when wearable sensing described for the first time is set
The standby 21 wearable sensing apparatus 1 apart from the height on ground and after first time is more than pre- apart from the difference of the height on ground
If during difference, you can judge that user falls down.Such as during the normal bathing of user, the first time wearable sensing apparatus 21 that measures
Height apart from ground is L1, and the wearable sensing apparatus 21 after then carrying out once first time every 5 seconds is apart from ground
The detection of the height in face, height of the wearable sensing apparatus 1 apart from ground after first time is arranged to L2, then meter
Calculate L1 and L2 difference, when user falls down, the difference between L1 and L2 can be more than preset difference value, when controller 3 twice in succession
When measuring the difference between L1 and L2 above and being more than preset difference value, you can judge that user falls down.In the present embodiment, above-mentioned default difference
Value could be arranged to 0.5 meter.

When controller 3 judges that user falls down by the first detection means 1 and second detection device 2, now due to two
Individual detection means provides identical result, then illustrates that user falls down really, and judged result is more accurate, reduces exclusive use
False Rate when one of which detection means is detected, the now control of controller 3 alarm module alarm, prompts user relatives to use
Fall down at family.
When controller 3 is judged as using by one of detection means in the first detection means 1 and second detection device 2
Family is fallen down, and when another detection means is judged as that user does not fall down, alarm module is not alarmed directly, above-mentioned first detection means 1
Continue to detect with second detection device 2, it is multiple when detecting, if controller 3 passes through the first detection means 1 and the second detection
Judged result after device 2 is detected is identical, and controller 3 is then operated accordingly according to judged result, if remained
One of detection means is judged as that user falls down, and when another detection means 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.
