Detailed description of the invention
Below with reference to drawings and Examples, this utility model is described further, but should not limit with this
Make protection domain of the present utility model.
For convenience of explanation and understand the noun of locality that the technical solution of the utility model, following description are used
The orientation all shown with accompanying drawing is as the criterion.
As depicted in figs. 1 and 2, a kind of body height measuring device of the present utility model, including housing 1, installing
Display 2 on housing 1 and the circuit board being installed in housing 1, described circuit board is provided with signal and sends out
Penetrate module 3, signal receiving module 4, processor 6, voice module 7 and power module.Described processor
6 are electrically connected with described signal emission module 3, signal receiving module 4, voice module 7 and display 2 respectively
Connect.Described power module respectively with described processor 6, signal emission module 3, signal receiving module 4, language
Sound module 7 and display 2 electrically connect, for described processor 6, signal emission module 3, signal
Receiver module 4, voice module 7 and display 2 are powered.Described signal emission module 3 is used for sending letter
Number, being received by signal receiving module 4 after this signaling reflex, described voice module 7 is for the height that will record
Value is converted into voice, and processor 6 is for judging phase shift and the time of signal.
Described signal is set to ultrasonic signal or infrared signal or laser signal, in the present embodiment, and institute
State signal and be set to ultrasonic signal.Owing to ultrasonic locating technology volume is little, directivity is strong, intensity is easily-controllable
System, energy expenditure slowly need not the advantage directly contacted with object being measured, are therefore widely used in range finding.
Ultrasound wave refers to that frequency is higher than the mechanical wave of 20KHz, and in general frequency is the highest, and precision is the highest, but
Because attenuation of air increases, nearer distance therefore can only be detected.Within being generally 3m because of height, Er Qieyao
Refinement degree is the highest, and the ultrasonic frequency therefore used in the present invention is between 20KHz～100KHz, excellent
Choosing, ultrasonic frequency is set to 40KHz.
Ultrasound height utilizes reflection characteristic exactly, constantly launches 40KHz by signal emission module 3
Ultrasound wave runs into barrier back reflection and returns echo, then receives reflection wave signal by signal receiving module 4,
And it is converted into the signal of telecommunication.Ultrasound examination often relatively rapidly, convenient, calculate simple, be prone to accomplish
Control in real time.
The principle of ultrasound height is that signal emission module 3 at a time sends a ultrasonic signal,
Return by received by signal receiving module 4 when running into testee back reflection.Signal emission module 3, letter
Number receiver module 4 is sent to processor 6 the transmission information of ultrasonic signal, reception information respectively, processes
Device 6 obtains the time difference that ultrasound wave sends and receives.Get the time difference that ultrasound wave sends and receives, just
The position distance to testee of ultrasonic emitting can be calculated.Computing formula is as follows: d=s/2=(c*t)
/2.D is the distance that testee arrives the position of ultrasonic emitting, and s is the distance back and forth of ultrasound wave, and c is
The velocity of sound, t is the time difference that ultrasound wave sends and receives.Thus processor 6 by obtain ultrasound wave send and
The time difference received calculates the phase shift of ultrasonic signal, thus obtains height data.Height measures process
Intellectuality, DATA REASONING quick and precisely, uses safety.
During specifically used body height measuring device of the present utility model, first measure sound source and the ground of body height measuring device
Distance between plate is designated as d1, and measured stands in the lower section of sound source of body height measuring device, then measures height and survey
Distance between sound source and the crown of measured of amount device is designated as d2, calculates d1 and d2 by processor
Between range difference be the actual height values of person to be measured.Periphery unobstructed barrier is selected during measurement, it is to avoid
The interference of the different ultrasonic signals being reflected back.
Because the speed of ultrasound wave is different under different indoor humidities, and speed Different Effects is last
The precision measured.Therefore the present embodiment have employed humidity sensor 5 and carry out velocity compensation, when being embodied as,
Humidity sensor 5 detects current humidity in real time, and this humidity information is sent to processor 6, processor 6
The ultrasonic velocity extracted under corresponding humidity calculates, thus improves the precision of measurement result.
Bluetooth technology is the radiotechnics of a kind of holding equipment short haul connection (in general 10m).Energy
Including entering between the relevant external equipments such as mobile phone, media player, notebook computer, intelligent watch
Row wireless messages exchanges.The wireless data output module electrically connected with processor 6 it is additionally provided with on described circuit board
8, described wireless data output module 8 can be communicatively coupled with mobile terminal, for by height data from
Processor 6 is derived to terminals such as mobile phone, flat board, computers and is carried out showing and/or managing, it is achieved intelligent measure,
And record can be facilitated.In the present embodiment, wireless data output module 8 is preferably bluetooth module, described indigo plant
Tooth module utilizes BLE4.0 agreement to communicate.Processor 6 controls the height data recorded to be shown aobvious
Show that, on device 2, display 2 uses liquid crystal display.The height data recorded is transmitted extremely by simultaneous processor 6
Voice module 7 also carries out being converted into voice by voice module 7, reports to user.
The announcement of book and teaching according to the above description, this utility model those skilled in the art can also be right
Above-mentioned embodiment changes and revises.Therefore, this utility model is not limited to be disclosed above and describe
Detailed description of the invention, should also be as falling into power of the present utility model to modifications and changes more of the present utility model
