Abstract

Disclosed is an ultrasonic two-dimensional human body measurement device comprising a base, a height-head having an ultrasonic wave emitting and receiving sensor and a single-chip microcomputer for controlling thereof and a vertical pole, wherein the single-chip machine as a local machine connects with the host computer inside the main control machine frame via a cable, an ultrasonic emitting and receiving matrix is installed on the lower bottom of the height-head and a standing position indicator is provided on the base. The invention introduces conceptions of the body length and body height which enriches the basic parameters in body measurement. It can judge the standing posture is vertical enough or not, accordingly, the measurement error is reduced and the measured height is more accurate. The device may also be used to correct standing posture by indication of the measured value.

Description

Ultrasonic two-dimensional measuring instruments for anthropometry and measuring method thereof

Technical field

The present invention relates to the measurer of human stature device, especially utilize the gauge of ultrasonic measurement human body height.

Background technology

The air dielectric supersonic technique more and more is being used aspect the measurement human body height at present.This measurement is to adopt computer-controlled intelligent one-dimensional measurement commercial measurement human body height basically.Promptly human body vertically stand above ultrasonic sensor is installed.By the time of calculating ultrasonic emitting and return (through the certain calculation method), draw the numerical value of human body height at last.

This method Purely mechanical, mechanical electronic mode, photoelectric type measuring instrument relatively in the past has very big revolutionary progress.It is the due quality of gauge that measure theory, measuring method, measuring operation have all embodied current information-intensive society.Be subjected to the general favorable comment of applying unit.The same with the development of anything, along with progressively going deep into of promoting the use of, we have also progressively found the deficiency and the improved method of this one-dimensional measurement technology.

This unidimensional measurement height technology has a kind of prerequisite of supposition: promptly everyone attitude of standing all is identical with straight.If can not guarantee each people's the attitude of standing correct, measure under these circumstances, just may make the error increasing of measuring conclusion.For this problem clearly is described, we introduce height and two notions of height, the height of human body and the height of human body are distinguished and are defined, to improve the notion of two-dimensional measurement.Human body is when standing, and there is corresponding relation a part of sole and a part on the crown.The people that ideal pose is stood, the result of the linear measure longimetry of direction is this person's a height from top to bottom, this moment, height equaled height.If the people bends over when standing, bow-backed, belly etc. very, make vertebra before and after taking place when crooked.This corresponding relation will change.At this moment, the result of the vertical length of direction measurement is this person's a height from top to bottom, but obviously short than this person's height.

In practical experience of life, the incomplete exactly vertical attitude of standing of the attitude that most of people stand.This just makes the degree of accuracy of measurement reduce greatly.So we not only will measure the height of human body, to consider that also the head of human body and the relative position of foot change.This factor is joined among the measurement result of this person's height.So just can provide height numerical value relatively more accurately to the detected person.

Summary of the invention

Goal of the invention of the present invention is for a kind of ultrasonic two-dimensional measuring instruments for anthropometry that can more accurate measurement body ' s stature is provided.

The technical scheme that realizes the foregoing invention purpose is as follows:

The ultrasonic two-dimensional measuring instruments for anthropometry, comprise base, height head and vertical rod, ultrasonic emitting and receiving sensor matrix and control single chip computer are housed in its camber head, control single chip computer is connected with main frame in the main control system case by cable as handset, on the bottom surface of height head the ultrasonic emitting receiving matrix is housed, on base, is provided with the erect-position point.

Has LCDs on the described main control system.

Have minitype thermal printer interface and voice suggestion on the described main control system.

Described base is the weight electronic scale, and the erect-position point on the base is the erect-position reference point.

Another goal of the invention of the present invention is for a kind of measuring method of using the ultrasonic two-dimensional measuring instruments for anthropometry to measure human body height is provided.

The ultrasonic body measuring instrument is measured the measuring method of human body height, comprises the following steps:

A. ultrasound wave sends ultrasound wave, receiving matrix relative position and the height value according to the ultrasound examination human body peak that returns, and deposits single-chip microcomputer in;

B. compared with human body erect-position reference point in the peak position, if deviation is arranged then carry out next step, if conform to then execution in step d;

C. according to the position of peak and the horizontal range of human body erect-position reference point the length of peak is revised, drawn actual height, correction formula is as follows:

$X=X_1+X_2,X_1=\sqrt{D^2+{(H-X_2)}^2}$ So

$X=\sqrt{D^2+{(H-X_2)}^2}+X_2$

Wherein: X is the height of the measured,

X ₁Be the length (length of hypotenuse) of crooked starting point to the peak on the crown,

X ₂Be the length of crooked starting point to sole,

D is by the horizontal distance of erect-position reference point to the measured crown peak,

H is that the height of standing of the measured is a height;

D. show measurement result.

In above-mentioned measuring method, if the measured when measuring, vertebra is case of bending, then by health stand vertical direction foot upwards, by the crooked starting point beginning, till the height on the crown.There is a right angle triangle to exist.

What measure is a right-angle side D of above right angled triangle by the erect-position reference point to the horizontal distance of the measured crown peak, is another right-angle side H-X of above right angled triangle to the health peak by bending point ₂And this hypotenuse be the measured by the height X of bending point to the crown ₁

The height of the measured that so X is us to be required, rather than the height H of the measured.Here height and height are unequal.

In the above expression formula if D=0, then X=H.This is the height that the people of correct stance is arranged.Here height and height equate.

The certainty of measurement that ultrasonic emitting that we adopted and receiving matrix are reached provides technical assurance to above calculating.

The height that we propose, the notion of height.And height equals the notion of height under qualified situation.The value of its existence is only just arranged under our this measuring technique method and the human body attitude of standing is had gauged meaning.

For H-X ₂Determining of point.Here provided crooked starting point for most spinal curvature persons as H-X ₂Do not do consideration for special case history.

The present invention distinguishes the vertical degree of people's stance, again with this vertical degree as parameter, be updated among the computing that the human body height measures.Make people's body length of recording and highly more accurate, significantly reduced measurement error, the detected person can learn by measurement result whether stance is correct simultaneously, reaches the effect of proofreading and correct stance.
