Description
Technical field
The present invention relates to correction chair technical field, more particularly, to the SCM Based three roads ultrasonic wave correcting sitting posture of one kind
Chair.
Background technology
With science and technology progress and society development, increasing student at school with learning process due to not
Correct sitting posture and do not get enough athletic exercise, result in a series of unhealthy problems such as myopia, hunchback, caused to vast teen-age health
It is great unfavorable, and correcting sitting posture chair design traditionally according to human body back away from chair distance detection sitting posture, can be big
Cause calculates human body sitting posture, completes detection typically only with a ultrasonic sensor due to detection traditionally, it can not be right
Teen-age back is comprehensively detected that error is big, is detected inaccurate.
Therefore, it is necessary to provide a kind of new technical scheme to overcome drawbacks described above.
The content of the invention
It is an object of the invention to provide a kind of SCM Based three tunnel ultrasound that can effectively solve above-mentioned technical problem
Ripple chair for correcting sitting posture.
To reach the purpose of the present invention, adopt the following technical scheme that：
A kind of SCM Based three roads ultrasonic wave chair for correcting sitting posture, including chair body, described SCM Based three

Electric transducer, one-chip computer module, A/D modular converters and alarm module, the ultrasound examination module are provided with three, and set respectively
On the back for being placed in the chair body, set gradually above and below the ultrasound examination module, the ultrasound examination module point
It is not connected with A/D modular converters, the pyroelectric infrared sensor is connected with A/D modular converters, the passive sensor
Device is arranged in the chair body, and the A/D modular converters are connected with one-chip computer module.
The one-chip computer module is connected with alarm module.
The alarm module is indicator lamp or buzzer.
Compared with prior art, the present invention has the advantages that：SCM Based three road of the invention ultrasonic wave is sat
Appearance correction chair is detected simultaneously by three tunnel ultrasound examination modules, and information is returned into one-chip computer module, and one-chip computer module leads to
Accurately algorithm is crossed, the information data returned simultaneously using three tunnel ultrasound examination modules carries out analysis judgement, judges with this
The sitting posture of people, this design not only greatly reducing the error of measurement to a certain extent, and super by the tunnel of Algorithm Analysis three
The information of sonic detection module detection, can more accurately judge the sitting posture of people, preferably avoid hunchback and bend over this phenomenon
Generation.
Brief description of the drawings
Fig. 1 is the structural representation of the SCM Based three roads ultrasonic wave chair for correcting sitting posture of the present invention；
Fig. 2 is the structure annexation signal of the SCM Based three roads ultrasonic wave chair for correcting sitting posture of the present invention shown in Fig. 1
Figure.
Embodiment
Clearly complete is made to the SCM Based three roads ultrasonic wave chair for correcting sitting posture of the present invention below in conjunction with accompanying drawing
Explanation.
As shown in Figures 1 and 2, the SCM Based three roads ultrasonic wave chair for correcting sitting posture of the present invention includes chair body, set
Three ultrasound examination modules (1,2,3) for being placed on the chair body back, pyroelectric infrared sensor, single-chip microcomputer mould
Block, A/D modular converters and alarm module.
As shown in Figures 1 and 2, the chair body is normal chair on the market.The ultrasound examination module is set
There are three, and be respectively arranged on the back 5 of the chair body, the ultrasound examination module (1,2,3) sets successively up and down
Put, the distance between the ultrasound examination module 1 and ultrasound examination module 2 are s1, the ultrasound examination module 2 and institute
The distance between ultrasound examination module 3 is stated for s2.
As shown in Figures 1 and 2, the ultrasound examination module (1,2,3) is connected with A/D modular converters respectively, described red
Outer pyroelectric sensor is connected with A/D modular converters, and the pyroelectric infrared sensor is arranged in the chair body, described
Pyroelectric infrared sensor is used for whether having personnel in detection chair body in real time.The A/D modular converters are used to believe simulation
Number data signal is converted into, the A/D modular converters can be by ultrasound examination module (1,2,3) and pyroelectric infrared sensor
Detection analog signal conversion be in data signal, then by digital data transmission to one-chip computer module, the A/D modular converters with
One-chip computer module is connected.The one-chip computer module is single-chip microcomputer common on the market, and it belongs to prior art, therefore no longer goes to live in the household of one's in-laws on getting married herein
State, the one-chip computer module can be handled the data signal that A/D modular converters are changed.The one-chip computer module and alarm
Module is connected, and the single-chip microcomputer can send instruction to the alarm module makes it send alarm, and the alarm module can be
Indicator lamp or buzzer etc., to cause the attention of seated user.
As shown in Figures 1 and 2,4 in figure represent teen-age back, and 5 be the back of chair body, the ultrasonic wave inspection
The position that the ultrasonic wave that survey module (1,2,3) is sent is transferred to teen-age back corresponds to (6,7,8), the ultrasonic wave respectively
The distance that detection module (1,2,3) is detected is respectively d1, d2, d3, wherein the straight line between 6 and 7 is defined as a, between 7 and 8
Straight line be defined as b, the straight line between 6 and 8 is defined as c, and the angle between straight line a and straight line b is e, whereinB and c can be similarly obtained, according to the mathematics cosine law：Cos θ=(a2+b2-c2)/(2ac) can be with
Obtain θ angles.The span at θ angles is (180 degree<θ<230 degree), one-chip computer module is according to the angle calculated by above-mentioned steps
With the angle changing rate of setting, within the unit interval, if θ is less than 165 degree always, one-chip computer module, which will be deemed as user, camel
Phenomenon is carried on the back, subsequent signal makes it send alarm to alarm module.
As shown in Figures 1 and 2, the SCM Based three roads ultrasonic wave chair for correcting sitting posture of the present invention is in use, first
When teenager is not in chair body, the pyroelectric infrared sensor, which can be detected, does not have personnel on chair, now
It is in data signal by analog signal conversion that signal, which is sent, to A/D modular converters, is then transmit in one-chip computer module, by single-chip microcomputer
Module sends instruction to ultrasound examination module (1,2,3), closes it, now red when there is personnel to be sitting in chair body
Outer pyroelectric sensor, which is detected in chair body, has personnel to be seated, and now sends signal to A/D modular converters, the A/D turns
It is in data signal that block, which is changed the mold, by the conversion of its signal, is then transmit to one-chip computer module, and the one-chip computer module, which is sent, to be instructed to super
Sonic detection module (1,2,3), makes it start working.The data that three ultrasound examination modules (1,2,3) are detected are sent
To A/D modular converters, it is converted in data signal, is then calculated by one-chip computer module after above-mentioned mathematical operation processing
θ size, if θ is less than 165 degree always, one-chip computer module, which will be deemed as user, bow-backed phenomenon, subsequent signal to alarm
Module, makes it send alarm.
