Description

Portable multi-function physical health of students electronic instrument for evaluating

The utility model relates to a kind of contrast, calculating, evaluation, judgement physique constitution of students situation, physical education, the administration of health of health status and physical training situation up to standard, electronic equipments of medical matters health care of being used for.

Children and youth is the future of motherland, is the hope of development socialist economy, and they grow and healthy physique, are the bases of Kang Qiang nationality, are the ingredients of education.Correctly the blue or green juvenile's of evaluation physique, health status are very difficult things but in the middle of actual.At present existing national evaluation of physical fitness and health standard, standard for physical training and nutrition and fertile standard are applied to actual physical health of students comparative evaluation, but because content is many, consult inconvenience, need carry out a large amount of computation of table lookup, so school, the head of a family and student all can not get accurate evaluation to physical health of students, domestic existing research also just by robot calculator, is carried out the software program design, and involve great expense, should not apply." WXR-EA child health care computer " by the development of Chinese Medical Association Jiangsu Province Suzhou branch just carries out anthropometic from six indexs of child's form to children, build, the evaluation of nutrition condition, it is by LED display and diode displaying, there is no printout, the instrument that just is used for young infant health, and big to 7-22 years old in the school, in, the pupil carries out the good and bad evaluation of physique health care, must be according to the physique constitution of students evaluation criterion of country's formulation, standard for physical training and nutrition and obesity standard carry out comprehensive comprehensive evaluation, the quality that could reflect physique constitution of students like this, fitness quality, and nutrition and fat situation.

The physique constitution of students of at present existing physical construction is estimated instrument, searches the contrast inconvenience but still exist, the few shortcoming of function.

The purpose of this utility model, promptly be the problem that exists at prior art, and a kind of " portable multi-function physique constitution of students health care electronic instrument for evaluating " that is suitable for popularization of design have man-machine conversation, the store information amount is big, function is many, and range of value is wide, and is simple to operate, volume is little, characteristics such as easy to carry also have printout, use very convenient.

Illustrate with reference to the accompanying drawings how the purpose of this utility model realizes:

Fig. 1 is the utility model structured flowchart.

CPU is a microprocessor among the figure, and ADDR is a data latches, in order to produce the most-significant byte address signal, RAM is a data latches, and EPROM is a program storage, and LCD-DRV is a liquid crystal driver module, I/O is the expansion IO interface, in order to connect keyboard KEY and TP μ P mini-printer.

Because the utility model will be realized multiple function, just need the storage lot of data, Chang Bianliang and handling procedure and a small amount of Chinese character dot matrix code just require system to have bigger storage capability, and the utility model adopts a slice 64KEPROM to realize above-mentioned storage work.

Estimate in the instrument course of work, need the many measured datas of storage and carry out a series of computings, comparison, operation, this just requires system disposition that enough data-storing districts are arranged, and the utility model adopts a slice 32K static RAM chip to make the data memory.

This evaluation instrument has the man-machine conversation function, also the printout function will be arranged, and realizes these functions, only according to the interface resource that CPU provided is not enough, has so just required the expansion IO interface, in order to connect the ranks keyboard, and provide printer interface, I/O be the expansion IO interface.

The utility model adopts dual bus formula hardware configuration, 8 bit data bus D ₀～D ₇Meet the P of CPU _0.0～P _0.7, 16 bit address buses are divided two parts, most-significant byte A ₈～A ₁₅Meet the P of CPU _2.0～P _2.7, least-significant byte A ₀～A ₇Meet ADDR output terminal Q ₀～Q ₇, ADDR input end D ₀～D ₇Meet data bus D ₀～D ₇, LE termination cpu address latchs control end ALE, output terminal Q ₀～Q ₇, be the least-significant byte address signal.

The address wire pin A of EPROM ₀～A ₁₅Ground connection location bus A ₀～A ₁₅, data line pin D ₀～D ₇Meet data bus D ₀～D ₇, sheet selects end CS ground connection, and output allows end OE to connect the CPU sheet and gets charge making pin PSEN outward.Like this, the EPROM address is from 0000H to 0FFFH.

The address wire pin A of RAM ₀～A ₁₄Ground connection location bus A ₀～A ₁₄Data line pin D ₀～D ₇Meet data bus D ₀～D ₇, the first chip select line CS ₁Ground connection, the second chip select line CS ₂Connect+the 5V power supply by resistance R.The P of CPU _1.0End is through phase inverter NOTI and WR and the CD end passes through respectively or door OR ₁And OR ₂Link to each other with the OE end with the WE of RAM.Address ram is from 0000H to 7FFFB like this.

The data line pin D of I/O mouth ₀～D ₇Meet data bus D ₀～D ₇, port address selection wire A ₀A ₁Ground connection location bus A ₀A ₁, address wire A ₂Through phase inverter NOT ₂P with CPU _1.0By or the door OR ₄Contact pin choosing end CS, the PA mouth connects keyboard row line, and the PB mouth connects TP μ P mini-printer, and the PC mouth connects the keyboard alignment.The PA of I/O mouth, PB, PC and control port address are that 0FFFCH is to 0FFFFH.

LCD-DRV data line pin D ₀～D ₇Meet data bus D ₀～D ₇, read-write control pin R/W meets address wire A ₁, RS termination address wire A ₀, address wire A ₂P with CPU _1.0By or the door OR ₃Contact pin choosing end E, like this, the address 0FFFBH-0FFFBH of LCD-DRV module.

With above-mentioned hardware configuration basis, establishment one cover software can be finished several functions such as " student nutrition is estimated with fat ", " National Standard for Sports Training scoring ", " physique constitution of students evaluation ".The input measured data, can draw evaluation conclusion and can show, storage, print output data.

Such as: " nutrition is estimated with fat " at first by the operation of keyboard KEY-series, selects " nutrition is with fat " Function of Evaluation submenu to select, and CPU is earlier by address bus A ₀～A ₁₅Search " age " kanji code in EPROM, kanji code is by data bus D ₀～D ₇Be sent to LCD-DRV, at this moment display will show " age " printed words, and keyboard KEY imports age data, and these data are by data bus D ₀～D ₇Send among the RAM, also send into the LCD-DR display simultaneously and show age value.The same operating process, by KEY keyboard input " height ". " body weight " CPU utilizes form and the operational formula of " height ", " age " data and EPROM, draw measured's standard body weight, compare according to corresponding evaluation criterion and measured's body weight among the/EPROM then, reach a conclusion, by data bus P ₀～P ₇Be sent to LCD MODULE LCD-DRV display and will show " normally ", " obesity " or " malnutrition " or the like, press the printing keyboard of keyboard KEY, evaluation result is by I/O, and the PB mouth is sent into TP μ P, can the printout evaluation conclusion.

The utlity model has " physique constitution of students evaluation ", " National Standard for Sports Training scoring " and reach " nutrition is estimated with fat " three functions.Simultaneously also have the man-machine conversation function, easy for operation, volume is little, and is in light weight, is easy to carry.All can popularize use in the schools of various levels and categories, sports management and medical department.It is a kind of physical health of students electronic instrument for evaluating that has promotional value.

Below in conjunction with Fig. 2, enumerate a most preferred embodiment of the present utility model, CPU adopts 80C31, and address latch adopts 74CS373, ROM 27C512, RAM adopts 6264, and I/O adopts 82C55, and LCD-DRV adopts HD61830, NOT ₁, NOT ₂Adopt 74LS04, OR ₁～OR ₄Adopt 742532, can finish above-mentioned functions.
