Description
Technical field
The invention belongs to field of artificial intelligence, are related to machine learning, mode identification method more particularly to a kind of base
In the ergonomics intelligent bed and its application method of " perception-action " unit.
Background technology
Traditional bed has the disadvantage that：First, there is vertebra health and adversely affect in conventional mattresses.For there is abundant bullet
For the mattress pad of property, the adverse effect of lumbar vertebrae is well-known；And for hard mattress, in not optional equipment waist
In the case of pillow, the physiological bending of lumbar vertebrae, which is in the gap formed between bed, still can make lumbar vertebrae in tension.And it is equipped with
After waist pillow, the actions such as the turn of user in one's sleep also influence whether the position of waist pillow, to make waist pillow failure, or even generate anti-
Effect.Secondly, conventional mattresses can not adapt to different sleeping position demands.It is taken together it is well known that people are not necessarily in sleep
One sleeping position, it often can be along with the change of sleeping position in sleep procedure.And different sleeping positions also differs the compressing of body,
For example the shoulder being below when lying on one's side can be oppressed more, and when compared to lying low, pillow height when lying on one's side is also required to more
It is high；Double embrace and when sleeping, the arm of a side can be oppressed under the body of another party, easily cause thrombosis, severe patient
Once having leads to the case of amputation；Tiptoe can be fought with bed board when prostrate, be forced to stretch so that the instep moment is in
State is unfavorable for sleeper and loosens, while body can also influence the compressing of heart sleep health when prostrate；Sitting and lying is partly sleeping
When, the gap between user's low back and mattress is unfavorable for vertebra health, and since buttocks lacks lateral support, leads to user's body
Cognition keeps falling, and influences user experience.
It is several sections that intelligent health bed on the market, which is all by bed board horizontal partition, at present, passes through machinery between section and section
Structure is connected, and is needed to be adjusted each intersegmental angle according to user, to adapt to the lumbar curve of user, or adapts to sit
The different demands of appearance and prone position.But there is also drawbacks for this structure, and first, which is only divided bed in one dimension
Sleeping position is different with body structure when cutting, can not adapt to two people or more people while using and the different demands brought.Secondly, will
The block number of bed board segmentation is less, can not really realize to vertebra omnidirectional support.It only carries out horizontal partition, nothing to bed board again
Method realizes that posture adapts to the asymmetrical sleeping position such as lie on one's side.
Invention content
The problem of being proposed for the prior art, the present invention provide a kind of ergonomics intelligence being based on " perception-action " unit
Energy bed and its application method, solution bed can not be realized scientific and reasonable to the progress of sleeper's body under conditions of more people more sleeping positions
Support the problem of.
In order to achieve the above object, the technical scheme is that：
One kind being based on the ergonomics intelligent bed of " perception-action " unit, including multiple " perception-action " units 1, bed body
2, the head of a bed 3, central control module and corresponding control device.The central control module is placed in bed body or the head of a bed.Electric appliance
Configuration aspects, all " perception-action " units 1 are all connected with central control module, and the pressure result of perception is sent to
Entreat control module；After central control module identifies the sleep posture of sleeper, by corresponding control device (such as motor, hydraulic pressure
Driving circuit and screw rod driving motor) each " perception-action " unit 1 of control expanding-contracting action.In terms of mechanical structure,
Several described " perception-action " units 1 are combined into bed board, and bed board is set to 2 top of bed body, and the head of a bed 3 is located at 2 side of bed body,
As shown in Figure 1, making bed board generate rational curved surface by making different " perception-action " units 1 generate the flexible of different length.
Each of described " perception-action " unit 1 includes perceiving and acting two parts, and the two is in upper and lower arranged in series.Institute
The sense part stated point includes perception part enclosure 4, pressure sensor 5, pressure sensor position-limit mechanism；Pressure sensor 5 is located at
It perceives inside part enclosure 4, for perceiving pressure；The setting of pressure sensor position-limit mechanism is perceiving inside part enclosure 4,
For the stroke that restriction aware part enclosure is depressed, cause to damage to avoid pressure sensor 5 from being excessively pressurized；The sense
Know that part enclosure 4 can also also serve as position-limit mechanism.The action part controls perception-action according to central control module " it is single
Member 1 elongates or shortens, its Telescopic is realized by hydraulic pressure, air pressure, screw rod or motor etc..
The arrangement mode of described " perception-action " unit 1 can be that rectangular, cellular, cylinder is staggered or triangle
Shape is staggered etc.；" perception-action " unit 1 can be according to user's needs, other function modules of additional, such as air circulation mould
Block, heating module, drug delivery module etc..
The application method of ergonomics intelligent bed of the one kind based on " perception-action " unit, includes the following steps：
The first step is tested when system is designed by a large number of users, determines human pressure's distribution characteristics when sleep
1.1) action part for owning " perception-action " unit 1 is locked, bed board is made to remain a plane.
1.2) tested person lies on bed board and sleeps, and record sleep posture and corresponding " perception-action " unit 1 are perceived
Pressure data.
1.3) according to a large amount of pressure datas, and the body parameter (height, weight etc.) of user is combined, establishes different sleep appearances
Pressure model under state.
1.4) according to medical data, the people for establishing different physical traits is under different sleeping positions, the three-dimension curved surface on the downside of body
Model.
Second step, user use process
User is in use, system calls corresponding body curved surface according to the collected bed board pressure distribution of perception part institute
Model makes it approach body surface model, adapts to the sleeping position of sleeper by control action partial adjustment bed board form.
2.1) specific pressure distribution situation when being slept according to user and body parameter input by user, in conjunction with step
1.3) obtained pressure model in identifies the sleep posture of user by pattern-recongnition method.The pattern-recongnition method can be with
It is established based on theoretical model or a large amount of measured datas, or be modified by the body parameter of user itself, including knn algorithms,
Svm algorithms, deep learning algorithm etc..
2.2) according to the sleep posture of the user obtained in step 2.1), the object function of bed board control, the function are generated
Can keep the pressure value of the pressure sensor 5 of all compressions identical, raising and the drop of action part are adjusted according to object function
It is low, make the compound ideal body surface model of the curved surface of bed board, provides better support to the user；
Or according to the sleep posture of the user obtained in step 2.1) after, the three-dimension curved surface that is directly obtained from step 1.4)
Model calls corresponding body surface model (being obtained based on N-Side surf improvement under ideal body) to make the compound reason of the curved surface of bed board
The body surface model thought, provides better support to the user.
Or organically combine the two, make the compound ideal body surface model of the curved surface of bed board, provides to the user more preferable
Support.
The invention has the advantages that in the case where the indefinite sleeping position of number of users is unlimited to the user science can be provided
Body-support, reduce unreasonable the caused uncomfortable and disease of sleeping.
