It is connected with switching switch, using the 5V voltage conversions by input is switched by switching as 3.3V voltages, wherein solar powered device
On the exterior wall of building where ward, solar powered device includes solar energy photovoltaic panel；
Netting collecting apparatus, is cylindrical vessel below sick bed, can Pop-up netting main body for storing；
Ejecting gun, respectively with DSP process chips and can Pop-up netting main body be connected, positioned at netting collecting apparatus rear portion, be used for
Receive fall trigger signal when, by can Pop-up netting main body be ejected into out of netting collecting apparatus the side of sick bed and from
In open mode；
Can Pop-up netting main body, before not sprayed by ejecting gun, remain in netting collecting apparatus and in contraction-like
State, is protected for the human body that fallen when being injected into the side of sick bed and in open mode to sick bed；
Weight rate detection device, positioned at sick bed bed board downside position, including weight detector and timer, weight detecting
Instrument is used to detect the load weight on sick bed bed board, output and meter of the weight rate detection device based on weight detector in real time
When device output determine load weight rate of change on sick bed bed board, when load weight rate of change is more than default rate of change, hair
Go out weight change pre-warning signal, when load weight rate of change is less than or equal to default rate of change, send weight change normal signal；
DSP process chips, respectively with image capture device, ejecting gun, weight rate detection device, target identification equipment and super
Acoustic wave detection devices are connected, and after weight change pre-warning signal is received, start image capture device, then there is people receiving
Body signal and when receiving object and skimming over signal, sends trigger signal of falling, is receiving no human body signal and receiving object
When skimming over signal, the pre-warning signal that falls is sent, and does not receive object and skims over signal and receives only and there is human body signal, is sent out
Go out the pre-warning signal that falls；
Mobile hard disk, for having prestored each benchmark human body image, each benchmark human body image is the base to the different bodily forms
Quasi- human body carries out the image for shooting and obtaining in advance, is additionally operable to prestore default square mean error amount, black and white threshold value, pixel count threshold
Value, preset strength and default rate of change；
Wherein, the frequency of the ultrasonic listening equipment is higher than 20000 hertz, and its lower-frequency limit is more than the upper limit of hearing of people.
