Abstract
This utility model relates to a kind of motion apparatus for measuring calories consumed, be worn on sporter's waist, the acceleration transducer, usb interface module and the display module that comprise microprocessor, be bi-directionally connected with microprocessor, wherein said usb interface module one end and microprocessor are bi-directionally connected, the other end connects USB interface, and the input of described display module is connected with the outfan of microprocessor.Compared with calculating the device of calorie consumption with employing traditional mechanical pedometer, this utility model meter step precision is greatly improved, and the calorie consumption amount obtained thus is also more accurate; Realize simple, integrated level is high, can embed in wearable smart machine, easy to carry.
Description
Technical field
This utility model relates to human motion and consumes calorie fields of measurement, especially a kind of portable motion apparatus for measuring calories consumed.
Background technology
Pedometer, as the welcome daily exercise watch-dog of one, is widely used, pedometer of the prior art, by data such as statistics step number, distance, speed, times, measuring and calculating calorie or heat exhaustion, in order to control quantity of motion, prevent quantity of motion deficiency or excessive movement.Mechanical pedometer cost compare is low, but its accuracy and sensitivity are very low, therefore uses traditional mechanical type pedometer to be difficult to obtain calorie consumption amount accurately.
Utility model content
In view of deficiency of the prior art, this utility model provides a kind of portable motion apparatus for measuring calories consumed, the problem such as overcome accuracy that prior art exists and sensitivity is low, accurately obtains the step number that people runs, thus obtains the amount calories of human consumption further.
For achieving the above object, this utility model is by the following technical solutions: motion apparatus for measuring calories consumed, be worn on sporter's waist, the acceleration transducer, usb interface module and the display module that comprise microprocessor, be bi-directionally connected with microprocessor, wherein said usb interface module one end and microprocessor are bi-directionally connected, the other end connects USB interface, and the input of described display module is connected with the outfan of microprocessor.We know that from the acceleration of foot to detect step number be the most accurately, but consider the convenience of carrying, and this utility model utilizes the motion of waist to detect step number.During walking, waist has upper and lower moving both vertically, and has a larger acceleration when often step starts, and utilizes the step number that just can obtain walking to the peakvalue's checking of acceleration.
Further, described display module is quaternity charactron.
Further, described acceleration transducer adopts acceleration analysis chip MMA7361.
Further, this utility model also comprises 5V power supply, for described microprocessor, described acceleration transducer and described display module provide electric energy.
This utility model reaches following beneficial effect: meter step precision is greatly improved, and the calorie consumption amount obtained thus is also more accurate; Realize simple, integrated level is high, can embed in wearable smart machine, easy to carry.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain this utility model, and be not used in restriction this utility model.
This utility model comprises microprocessor, usb interface module, acceleration transducer, display module and power supply, and annexation as shown in Figure 1.Be made up of as microprocessor, acceleration analysis chip MMA7361 acquisition module, USB2.0 function device chip CY7C68013 interface module, quaternity numeral method module AT89S52 single board computer in embodiment.With AT89S52 single-chip microcomputer for control unit, acceleration information is collected with 3-axis acceleration sensor, calculate calorie consumption amount through respective algorithms, utilize its value of LED quaternity numeral method, carry out high speed data transfer by USB interface and host computer simultaneously.
When people walks, foot, lower limb, waist and arm are all in motion, and their athletic meeting produces corresponding acceleration, and can put generation peak value at certain.We know that from the acceleration of foot to detect step number be the most accurately, but consider the convenience of carrying, and the motion of Selection utilization waist detects step number.During walking, waist has upper and lower moving both vertically, and has a larger acceleration when often step starts, and utilizes the step number that just can obtain walking to the peakvalue's checking of acceleration, as shown in Figure 2.After determining the step number that people advances, just can by calculating the amount calories of human consumption.
MMA7361 is a kind of capacitive acceleration transducer, and it has one pole filter, temperature-compensating, selftest, the zero gravity detector of energy detection of linear freely falling body, and the gravity selector that can make a choice between two susceptivenesss.As shown in Figure 3, this circuit major function is the converting interface being used as MMA7361 acceleration transducer, produces corresponding changing value.Be equivalent to the signal generator module of whole system.All connect RC low pass filter at each road signal output part of MMA7361, thus accomplished to reduce high-frequency noise interference on hardware.
In order to detect degree of accuracy of the present utility model, we have done following experiment: this utility model is arranged on the position that belt is kept right, according to the different azimuth of sensor, make three axles (X, Y, Z) of acceleration transducer MMA7361, the positive direction of (Y, Z, X) and (Z, X, Y) point to directly over the front-left of human body, human body respectively and people advance direction, carry out 7 experiments altogether, experimental data as shown in Figure 4.In experiment, X, Y of all tested objects and the data in Z axis 3 directions are adopted and processes in a like fashion.According to data analysis, the precision that can obtain pedometer reaches 95%, and this precision is ideal.
Technological means disclosed in this utility model scheme is not limited only to the technological means disclosed in above-mentioned embodiment, also comprises the technical scheme be made up of above technical characteristic combination in any.
