Description
Technical field
The present invention relates to a kind of wrist formula step count set based on upper arm swing, belong to body motion information detection technique field.
Background technology
The modern lacks physical training, easily causes the Chronic Non-Communicable Diseases such as heart disease, diabetes and cancer." the Chinese residents dietary guidelines " of Ministry of Health of the People's Republic of China issue pointed out: the motion body weight that not only contributes to the preservation of health, can also reduce the risk of chronic diseases such as suffering from hypertension, apoplexy, coronary heart disease, diabetes, colon cancer, breast cancer and osteoporosis." guide " suggestion adult should add up to be equivalent to above body movement of 6000 step of walking every day.Both domestic and external studies show that, the walking movement that takes large step, significantly swing arm is best to sanatory effect.
Passometer is convenient for carrying, easy and simple to handle, make people can monitor the walking step number of oneself every day, thereby obtained to use more and more widely.Human body when walking, the intermittence on sole and ground bump can make centre of body weight produce up-down vibration with the walking Frequency Synchronization in the direction perpendicular to ground, utilizes vibration transducer to detect moving up and down of centre of body weight, just can count the step number of walking.
At present, the structure from the vibration transducer of passometer has two kinds of mechanical sensor and electronic sensors.Mechanical sensor utilizes the wobble quality piece in the sensor to detect moving up and down of centre of body weight, be subjected to volume restrictions, mechanical sensor only has a wobble quality piece (sensitive direction), must to vertically wear when therefore using, make the sensitive direction of mechanical sensor perpendicular to ground, could the human body center of gravity move up and down.Electronic sensor is owing to adopting 3 axle microelectromechanical systemss (Micro Electro Mechanical Systems, hereinafter to be referred as MEMS) accelerometer, three mutually orthogonal sensitive directions are arranged, therefore no matter how 3 axis accelerometers are placed, and can detect moving up and down of gravity center of human body.
There is following defective in existing passometer:
(1) no matter be to adopt mechanical sensor or 3 axle MEMS micro-mechanical accelerometers, detection all be the up-down vibration of centre of body weight, the meter step, the result was subject to the impact that the extraneous vibrations such as elevator, the vehicles disturb;
(2) record is carried out in all foot's landings (step number), can't add up taking large step and effective step number of swing arm significantly, easily allow the user mislead.
Summary of the invention
The objective of the invention is to propose a kind of wrist formula step count set based on upper arm swing, arms swing number of times when detecting walking by sensor calculates step number, therefore the vertical vibration that the extraneous factors such as elevator, the vehicles is caused is disturbed insensitive, and the effective walking step number when only recording arms swing.
The wrist formula step count set based on upper arm swing that the present invention proposes comprises:
Shell is used for the swing of input arm, and shell is fixed on the arm by wrist strap;
Mass, for generation of with the motion of arms swing opposite direction, mass is fixed by screws in an end of flexure strip;
Flexure strip is used for supporting mass, and the displacement of mass is converted to the flexural deformation of flexure strip, and the other end of flexure strip is fixed by screws on the shell;
Resistance strain gage, the strain that both sides produce when being used for flexure strip flexural deformation is converted to resistance variations, and resistance strain gage is affixed on the both sides of flexure strip;
Electric bridge is used for the resistance variations of resistance strain gage is converted to change in voltage, and two resistance strain gages access respectively two adjacent in electric bridge arms;
Amplifying circuit is used for the voltage signal of electric bridge output is amplified, the input end of amplifying circuit and the output terminal of described electric bridge be connected;
Shaping circuit is used for the voltage signal of amplifying circuit output is shaped as square-wave signal, and the input end of shaping circuit is connected with the output terminal of described amplifying circuit;
Counting circuit is used for the pulse number of shaping circuit output is counted, and the input end of counting circuit is connected with the output terminal of shaping circuit;
Display screen is used for the count results that the demonstration counting circuit is exported, and the input end of display is connected with the output terminal of described counting circuit.
The wrist formula step count set based on upper arm swing that the present invention proposes, utilize spring leaf-mass system to experience arms swing, count by the number of oscillations that detects arm, because its sensitive direction is parallel to ground, therefore disturb to external world the health vertical vibration that causes insensitive; If the amplitude of arms swing is less, the flexural deformation that flexure strip produces is also little, causes the output voltage of amplifying circuit less than the shaping circuit threshold value, shaping circuit no pulse output signal; After only having the paces of increasing and amplitude swing arm, wrist formula step count set just begins counting.Therefore, what the wrist formula step count set that the present invention proposes showed is the significantly swing arm walking step number that body-building effect is had obvious effect, really walking step number, intensity and distance is carried out effective monitoring.
