Description

A kind of portable physical stamina test device

Technical field

The utility model relates to daily life, reaches the sports field, is a kind of device of portable physical stamina test, by the ultrasonic ranging principle, carries out physical stamina test.

Background technology

Along with the raising of people's living standard and constantly improvement, people are also more and more higher to the health requirements of self, and entire society is also improving constantly the requirement of the whole physical efficiency level of people.All kinds of middle and primary schools, institution of higher learning and army etc., often carry out a large amount of physical stamina tests and comparation and assessment.Common physical stamina test device, often complex structure, expensive, be not suitable for general family and unit and use and promote, and traditional physical stamina test device is with a lot of optional equipments, build is huge be not easy to mobile.In addition, some physical stamina test devices, take the transmitting-receiving of infrared-ray as basis, only can be realized counting and the feedback of single movement number of times, poor accuracy as a result, complicated operation and can not carry out storage and the contrast sequence of valid data, in all kinds of physical stamina tests or colony's match, applicability is poor.Therefore the intellectuality, lighting and the accuracy that realize physical stamina test have become inevitable trend.

Ultrasonic detection technology is due to advantages such as its high accuracy, harmless, noncontacts, and application is more and more extensive.Adopt ultrasonic detection technology to guarantee the accuracy of physical stamina test device, be aided with simultaneously wireless transmission and infrared remote sensing, simplify test operation, realize intellectuality, lighting and the accuracy of physical stamina test device, overcome the deficiency of existing other physical stamina test apparatus, will have very large application space and market prospects.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of portable physical stamina test device, use the ultrasonic ranging principle, the standard of testee's push-up and sit-ups is detected the calculating of go forward side by side places number and frequency, realized the simplification of physical stamina test, the portability of physical stamina test device, circuit is fairly simple, good stability, price are lower, is easy to extensive popularization.

The technical solution of the utility model is:

The standard of push-up and sit-ups detects takes testee's trunk to realize to the distance of this physical stamina test device., from being transmitted into the time difference of reflection receivable, calculated the distance of testee and physical stamina test device according to ultrasonic wave by formula X=T*340/2 by STC12C5A60S2 type single-chip microcomputer.When surveying push-up, ultrasonic range finder is put into athletic health below; When surveying sit-ups, ultrasonic range finder is put into the dead ahead of sportsman's trunk.When distance X is between setting value, count once and carry out auditory tone cues, when test finished, data were carried out statistical disposition and displaying time, number, frequency (f=n/t) etc. on the MzLH03-12864 liquid crystal in single-chip microcomputer.

In addition, can select, by wireless module, data are sent to computer VB interface, the integral body of carrying out achievement shows and rank; Convenient for this push-up counter is used, added sound prompt function, adopt WT588D speech chip and loudspeaker to carry out count off.

The beneficial effects of the utility model are:

(1) not only push-up and sit-ups are simply counted, can also standard degree and the frequency of push-up and sit-ups be detected and calculate;

(2) adopted SMD single-chip microcomputer, reduced volume and be easy to carry;

(3) adopt wireless transport module to realize wireless transmission, overcome the restriction of distance, realized long-distance transmissions;

(4) add computer VB interface display function, be convenient to collection, the storage of data, and marks sequencing;

(5) graphical interface, hommization, small volume and less weight, be easy to carry;

(6) can be widely used in middle and primary schools and the physical stamina tests such as all kinds of universities and colleges and army, in addition, press your body up from the floor with your arms and then lower it slowly match or sit-ups when match carrying out colony, do not need too much stroke counter, automatically detect because device has action criteria, improved the fair and just property of test and match.

The specific embodiment

Below in conjunction with accompanying drawing and specific implementation method, the utility model is described in further detail.

As Fig. 1: the physical stamina test device mainly by signal detection input, power supply change, reset, demonstration and processor of single chip computer five parts form.The critical piece of physical stamina test device comprises ultrasonic ranging system, buzzer, and 7805 power conversion systems, the LCD12864 LCD MODULE, voice module WT588D, by key control and reset key, wireless module, STC12C5A60S2 control section.Employing STC12C5A60S2 is control core, and the standard of push-up and sit-ups detects by the distance of detection testee trunk to the physical stamina test device and realizes., from being transmitted into the time difference feedback T of reflection receivable, calculated the distance of testee and physical stamina test device according to ultrasonic wave by formula X=T*340/2 by STC12C5A60S2 type single-chip microcomputer, if be in range of set value, buzzer ding-dong prompting, counting is once.After test finished, data, by the LCD12864 liquid crystal display, had voice suggestion simultaneously, had friendly man-machine dialog interface, and are both artistic and practical.

Fig. 2: the control system main control part adopts single-chip microcomputer STC12C5A60S2 to process the signal of ultrasonic wave module; display part shows with the LCD-12864 LCDs; having simultaneously the voice control section to carry out voice suggestion controls; power acquisition with 7805 voltage stabilizing moulds soon to its voltage stabilizing; play the holding circuit effect; the memory storage chip 24C02 that has in addition memory function carries out memory storage, has the function of remembering after outage.

Fig. 3: the ultrasonic ranging theory diagram has temperature-compensating velocity of sound function.

Fig. 4: after the device power supply, device will initialize, and liquid crystal display will show the initialization interface, and voice suggestion simultaneously " welcomes to use ".Does ultrasonic distance measuring module check whether distance meets setting value? if it is counter adds 1, and calculated rate, buzzer ding-dong point out this to move successfully, and if not not carrying out tally function, counting does not add, and frequency is constant.Stop key simultaneously detecting always and whether press, if by next voice broadcast: " you have been XX altogether, and frequency is YY "; If not being pressed, continues stop key to detect.
