Unless otherwise defined, technical and scientific term all used in this specification and the skill for belonging to the utility model
The normally understood meaning of the technical staff in art field is identical.Art used in the description of the utility model in this specification
Language, which is only for the purpose of describing specific embodiments, is not intended to limitation the utility model.
Fig. 1 is the structural schematic diagram that body provided by the embodiment of the utility model moves monitoring device.As shown in Figure 1, the dynamic prison of body
Surveying device 100 includes piezoelectric transducer 10 and control processing module 20.
Above-mentioned body moves monitoring device 100 and can be placed on bed, commonly use in mattress, in quilt cover, in pillow or with other days
Product match, and can preferably be placed in mattress body, and mattress body can use conventional mattress fabric, the dynamic monitoring dress of body
Set 100 and mattress body piezoelectricity mattress is collectively formed.In some embodiments, various shapes can be made in piezoelectric transducer 10,
Such as round, ellipse, rectangular etc., to be suitable for bed, mattress, quilt cover, pillow or shape with other articles for daily use a part
Shape.
In some embodiments, above-mentioned piezoelectric transducer 10 is to utilize sensor made of piezoelectric effect.So-called piezoelectricity
Effect refers to certain dielectrics in the external force by a direction and when deformation occurs (including bending and telescopic deformation etc.),
It, can be the phenomenon that its surface generates charge, in addition, the size of charge yield and external force has due to the polarization phenomena of internal charge
It closes, when external force is bigger, the yield of charge is more.When piezoelectric transducer 10 receives the body movement information of human body, piezoelectric sensing
Device 10 will generate charge, and export the charge as electric signal.The body movement information of human body refers to the vital sign of human body
Activity, such as heartbeat, breathing, body are dynamic etc..When human body is there are when vital signs activity, pressure of the human body to piezoelectric transducer 10
Variation will be generated, the deformation of corresponding piezoelectric transducer 10 can also generate, then piezoelectric transducer 10 exports electric signal and can also produce
Changing.
Optionally, above-mentioned piezoelectric transducer 10 can be piezoelectric film sensor 12.Piezoelectric membrane, that is, Kynoar is high
Molecular film (PVDF) is a kind of polymer that can be converted the kinetic energy into electrical energy after special processing, has very high piezoelectric effect.
When human body is placed on piezoelectric film sensor 12, the deformation that piezoelectric membrane is bent or is stretched, upper/lower electrode surface it
Between can generate electric signal, which can be current signal or voltage signal, and the size of the electric signal and piezoelectric membrane are bent
Or the deformation stretched is proportional.Piezoelectric membrane is usually very thin, and softness, density is low, sensitivity is fabulous, but also has very strong machine
Tool toughness, therefore electric signal can be effectively exported, to monitor the dynamic size of body.
It is understood that piezoelectric transducer 10 can also be other sensors, such as press in some other embodiments
Electric-type acceleration transducer, using piezoelectric ceramics or the piezoelectric effect of quartz crystal, when accelerometer is vibrated, mass block adds
Power on the piezoelectric element also changes therewith, such as when human body is placed on the piezoelectric transducer 10, since the life of human body is special
Sign activity, accelerometer is vibrated, then the electric signal of piezoelectric transducer output also changes therewith.
In the utility model embodiment, since when human body is placed on piezoelectric transducer 10, human body can be to piezoelectric sensing
Device 10 generates pressure, and the pressure can change with the activity of human body, and when the pressure change, corresponding, pressure
Electric transducer 10, which exports electric signal, can also generate variation, and therefore, control processing module 20 is used to be exported according to piezoelectric transducer 10
Electric signal, identification human body first is dynamic with the presence or absence of body, and body is dynamic if it exists, then identifies that the body dynamic duration and body are dynamic
Energy, and the energy that the duration moved according to the body and body move, calculate the dynamic size of the body.
It should be understood that although the vital signs activity of human body has very much, such as: heartbeat, breathing, body are dynamic etc.,
It is in all vital signs activities, body moves caused pressure change and is the largest, and presses caused by heartbeat and breathing
Power variation will not very greatly, therefore, detect human body moved with the presence or absence of body when, can by detection electric signal voltage amplitude whether
Mode more than a preset threshold is determined.
And the method for determination of preset threshold may is that body, which is moved monitoring device 100, first is horizontally arranged, human body lies low in body
In dynamic monitoring device 100, the maximum voltage value of piezoelectric transducer output in a period of time is detected, using the maximum voltage value as pre-
If threshold value.It is worth noting that: within this period of detection preset threshold, human body does not allow to carry out body and moves, and human body can only be put down
The quiet body that lies at moves monitoring device 100.
After obtaining preset threshold, when human body, which lies in body, to be moved in monitoring device 100, piezoelectric transducer 10 is exported
The amplitude and threshold value comparison of electric signal, if amplitude is greater than threshold value, body is dynamic, if amplitude is less than threshold value, it is dynamic that there is no bodies.
For example, if setting A=10 as threshold value, when human body, which lies in body, to be moved in monitoring device 100, electric signal that piezoelectric transducer 10 exports
For Y=X (t), work as t1When=5s, Y1=20, Y1Greater than A, then body is dynamic.
Wherein, identify that the dynamic duration specific embodiment of the body may is that control processing module 20 identifies body
After dynamic, from start to recognize body it is dynamic at the time of start recording, until body is dynamic to be terminated, intermediate this period is then that a body is dynamic
Duration.For example, if the electric signal that piezoelectric transducer 10 exports is Y=X (t), working as t after identification body is dynamic1When=5s, Y1
=20, work as t2When=10s, Y2It after=30,10s, is identified as no body and moves, then obtaining the duration that this time body is dynamic is T=5s.
Wherein, after identifying that the dynamic energy specific embodiment of the body may is that control processing module 20 identifies that body is dynamic,
From start to recognize body it is dynamic at the time of start recording, until body is dynamic to be terminated, intermediate this period, which is then that a body is dynamic, to be continued
The voltage amplitude of all electric signals within the duration that the body moves is added, obtained voltage amplitude sum by the time
The energy moved as body.For example, if the electric signal that piezoelectric transducer 10 exports is Y=X (t), working as t after identification body is dynamic1=
When 5s, Y1=20, work as t2When=10s, Y2After=30,10s, it is identified as no body and moves, 5s to the Y value between 10s is added up,
Cumulative method can be integral, and cumulative obtained value is the ENERGY E that the body moves.
Wherein, the energy that the duration and body moved according to the body are moved, calculates the specific embodiment party of the dynamic size of the body
Formula can be with are as follows: after identification obtains the body dynamic duration and the dynamic energy of body, the energy that body moves is continued divided by what body moved
Time obtains the dynamic size of body.For example, identification obtains the dynamic energy of the body and is if it is T that identification, which obtains the body dynamic duration,
E, then the dynamic size of body is L=E/T, it is assumed that identifies that obtaining the body dynamic duration is 5, identification obtains the dynamic energy of the body and is
20, then the dynamic size of body is 4.
