Abstract
The utility model relates to a measuring instrument for the body weight and the height of a person. The measuring instrument comprises an ultrasonic height-measuring device and an electronic weighing device. A printer, a display screen and a sex and age inputting device are arranged on the cabinet body of the measuring instrument. A central processor for receiving, processing and outputting height and body weight signals, and a database for storing the height and the body weight standard values of different sexes and ages are arranged in the cabinet body. The utility model gathers weighing, height measurement, evaluation and print into one body, and is suitable for more centralized public spaces of children. The measuring instrument can rapidly and conveniently monitor and evaluate the physical growth and nutritional status of children at any time everywhere.
Description
This utility model relates to a kind of height and weight measuring instrument of the child's of having physique test and appraisal function.
It is the major issue that each child head of a family is concerned about the most that child's healthy development is grown up.At present, in the child health care health check-up, the measurement of important indicators such as body weight, height, the automaticity of evaluation are not high, and the actual measurement of mass data, calculating and evaluation be mainly based on craft, and are confined to particular places such as hospital's children's health care outpatient service and carry out.Not only to rather inconvenience of the vast child head of a family who is busy with work, and be difficult to often child be carried out the anthropometic inspection.At present, the dynamo-electric conjunction type human body of existing a kind of being called " healthy recreational machine " altitude meter of weighing automatically on the market, but this machine adopts mechanical height measuring device, breaks down easily, and do not have child health care test and appraisal function.
The purpose of this utility model provides a kind of easy-to-use and automatic measurement human body height that is difficult for breaking down, the instrument of body weight, and this measuring instrument can be simultaneously carries out monitoring and evaluation to the growth promoter of children's physique.
The purpose of this utility model is achieved in that the height and weight measuring instrument comprises height measuring device, weight-measuring device and is connected the cabinet of surveying high weight-measuring device, be provided with printer and display screen are provided with reception, handle and export height, body weight signal in cabinet central processing unit on the cabinet, this utility model utilization ultrasonic measuring distance technology is provided with a cover ultrasound wave height measuring device; Also be provided with an age, sex input equipment and a data base who stores different sexes, age height, weight standard value.When measuring height and weight, sex, age data and height, body weight signal are sent into central processing unit in the lump, behind the central processing unit comparative evaluation, send into output device again, just can obtain height, weight data and the evaluation result of measurand simultaneously.
This utility model makes measurement human body height touch the non-type that touches that type becomes pure electronics from machinery, efficient and convenient, safe and reliable, realized height, the measurement of body weight and the assessment and the automatic print result of anthropometic feature especially simultaneously, for popularizing of child health care work provides convenience.
This utility model also can be measured adult's height, body weight and evaluation build.
Below in conjunction with drawings and Examples this utility model is further described.
Fig. 1 is the surface structure sketch map of a kind of embodiment.
Fig. 2 is that ultrasound wave is surveyed high principle schematic.
Fig. 3 is the electrical schematic diagram of ultrasound wave height measuring device.
Fig. 4 is the operation principle block diagram of a kind of embodiment.
Embodiment one: referring to Fig. 1, Fig. 4, electronic weighing device 1 of the present utility model, ultrasound wave height measuring device 5, display screen 4, lamp box 6, speaker 2 etc. are installed on the cabinet 7, standard value data base and central processing unit are arranged in the cabinet 7, on guidance panel 8 except that being provided with printer, above on and off switch, lamp box switch, volume adjustment knob and the key of checking out etc. also are installed in.Age of the present utility model, sex input equipment comprise one group of totally 32 throwing board mouth, and men and women's apportion the right and left, every row amounted to respectively and add an adult age in 15 year again in corresponding 3～17 years old, threw the board mouths for totally 16.
The operation principle and the structure of ultrasound wave height measuring device briefly are described below: the aerial spread speed of ultrasound wave is 340 meter per seconds, time according to its transmission can be calculated the distance of its transmission, and this utility model begins to calculate the human body height to reflected the time of being experienced by the human body crown from emission by measuring ultrasound wave.Referring to Fig. 2, Fig. 3.Ultrasound wave height measuring device of the present utility model is central processing unit to be received 9 with ultrasonic emitting 10, ultrasound wave respectively electrically connect, between central processing unit and emitting head 10, be provided with power amplifier, receive 9 and central processing unit between be provided with voltage amplifier and voltage comparator.During measurement, by the synthetic 40KHz ultrasonic pulse signal of central processing unit (8031) output process, the internal time enumerator picks up counting, this signal is delivered to emitting head 10(T40-16 after power amplifier 7407 power amplifications), emitting head 10 just converts electric impulse signal to ultrasonic emitting and goes out, when receiving a 9(R40-16) receive the ultrasound wave that reflects from the crown after, it is become the faint signal of telecommunication, this signal amplifies through multistage alternating voltage amplifier CA3140, send into voltage comparator LM311, AC signal is shaped to the Transistor-Transistor Logic level signal, and send to central processing unit and to interrupt application, stop timing, obtain the time t that ultrasound wave transmits back and forth, corresponding to V ≈ 340 meter per seconds in the S1=1/2Vt(formula).As shown in Figure 2, S1 and actual range S have minute differences, during actual test, and an emitting head 10 and receive 9 and lean on nearerly, when measuring distance surpassed more than 15 centimetres, θ was very little for angle of reflection, and error can be ignored after the software correction between S1 and the S.The difference of S0-S1 just can be thought the height values H of tested human body.Altimetry error of the present utility model is less than 1 centimetre.
Work process of the present utility model is described below: according to all ages and classes, sex, raise board and drop into corresponding throwing board mouth 3, testing circuit in the input equipment can detect measuring-signal very soon, speaker 2 and display screen 4 promptly send and show " please attention " prompting, and display screen 4 demonstrates the standard heights and the body weight value at corresponding sex age simultaneously.Then weight-measuring device is started working, in case measure the body weight value greater than liminal value (present embodiment is set at 5 kilograms), illustrate the people stood on weighing platform." please attention " on the screen to change to show is " in the measurement ", and begins to measure body weight and height in musical sound.Tend towards stability until two values, music stops, and promptly accuses test and appraisal and finishes.Screen increases the grade of the height, body weight value and two values that show actual measurement and tested person's physical characteristic, the measurement evaluation result of a Chinese of printout simultaneously.This utility model also is provided with the imput output circuit of calendar, hour hands.
Embodiment two: a cover sex, age input keyboard are set on guidance panel 8, sex, the age removed among the embodiment one are thrown board mouth group (or a measurement throwing board mouth is set), other structure is constant, during test, open measuring switch (or drop into to measure and raise board), sex, the age of input measurand on keyboard, then weight-measuring device is just started working.Following process and embodiment together repeat no more.
