Fig. 2 is the portable terminal vital capacity detection method with vital capacity measuring ability of the embodiment of the invention.

The specific embodiment

Vital capacity is meant under in unlimited time situation, the gas flow that do one's best and breathed out again after maximum inhale, and this represents the once maximum functional activity amount of lung, is one of important function criterion of reflection human body growth level.

A kind of portable terminal and vital capacity detection method thereof of the present invention with vital capacity measuring ability, clearer, clear and definite for making the object of the invention, technical scheme and advantage, below develop simultaneously embodiment to further explain of the present invention with reference to accompanying drawing.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.

A kind of portable terminal that the embodiment of the invention provides with vital capacity measuring ability; As shown in Figure 1; Comprisecentral processing unit 110; The real-time induction installation ofmike 120,air velocity density 130, volumedata blood processor 140,data storage device 170,distance detection device 150, apart fromconversion equipment 160, anddisplay screen 180.

Wherein, saidmike 120 is used to respond to the breath amount that the measured breathes out that receives.The real-time induction installation 130 of said air velocity density is connected with saidmike 120, the current rate of the breath amount that is used formike 120 is received and the volume high-low signal that lasting duration is converted into sound respectively and the lasting duration signal of sound; Induced air-flow in the present embodiment mainly is to make a decision through converting sound to, and the intensity of air-flow and time remaining length are converted into the volume height of sound and the persistent period length of sound.Concrete transfer principle is that known for example recently popular what blow that the skirt recreation adopts is exactly this technology.

Said volumedata blood processor 140 is connected with the real-time induction installation 130 of said air velocity density; Be used for obtaining the volume high-low signal of said sound and the lasting duration signal of sound from the real-time induction installation 130 of air velocity density; And be volumetrical current rate and lasting duration signal with the volume high-low signal of this sound and the lasting duration conversion of signals of sound, and this volumetrical current rate and lasting duration signal are carried out the volume treatment conversion is measured's vital capacity volume signals.Concrete realization can be adopted the device software (device of measurement gas pressure in the simulating reality) that an analogy U type pipe is installed.Utilize the difference of liquid in the U type pipe to come the volume calculated signal.

Saiddata storage device 170, be used to store this portable terminal of measuring in advance under distance to a declared goal with the mean error offset of standard vital capacity.

Wherein, this portable terminal can be through following method acquisition with the mean error offset of standard vital capacity under distance to a declared goal.D111, at first test out a plurality of people's standard vital capacity in advance through the vital capacity measuring instrument of standard; D112, measure the reference vital capacity (specifically being described in detail later) of above-mentioned a plurality of people's vital capacity volume signals conduct through mike, mike, the real-time induction installation of air velocity density, the volume data blood processor of embodiment of the invention portable terminal then; D113, with above-mentioned standard vital capacity of measuring and the difference that compares with reference to vital capacity, be this portable terminal under distance to a declared goal and the mean error offset of standard vital capacity.

Saiddistance detection device 150 is used to detect measured's measuring distance between position and the mike of exhaling; 3cm etc. for example.

Saidly be connected with saiddata storage device 170,distance detection device 150 respectively apart fromconversion equipment 160; Be used for obtaining said measuring distance fromdistance detection device 150; And according to this portable terminal under distance to a declared goal with the mean error offset of standard vital capacity, calculate the vital capacity error compensation value that under this measuring distance, should compensate automatically.

Saidcentral processing unit 110 is respectively with said volumedata blood processor 140, be connected apart fromconversion equipment 160; Be used for obtaining said measured's vital capacity volume signals from volumedata blood processor 140; And from obtaining said vital capacity error compensation value apart fromconversion equipment 160, and this vital capacity volume signals is added the actual vital capacity that the above vital capacity error compensation is worth the measured.

Saiddisplay screen 180 is connected with saidcentral processing unit 110, is used for the vital capacity that the measured is actual and shows.

In the present embodiment, said furtherdata storage device 170 also is connected with saidcentral processing unit 110, is used to store the actual vital capacity test result values of measured in a predetermined amount of time.

Saidcentral processing unit 110 also is used for the actual vital capacity test result values of measured in a predetermined amount of time is treated to trendgram and is shown to the user through display screen, and exports related advisory information automatically according to the actual vital capacity test result values of measured in a predetermined amount of time.For example detect numerical value low (comparing with regime values) when vital capacity, explain that body takes the photograph the ability of oxygen ability and combustion gas, the oxygen supply of inside of human body is just not abundant, and a few thing of body just can not be normal.In case body needs the wretched insufficiency that the situation (like long-time study, work, strenuous exercise time) of lot of consumption oxygen will the presence of oxygen supply; Thereby cause such as bad reflections such as headache, dizzy, uncomfortable in chest, lethargy, absent minded, hypomnesis, insomnias; This not only can influence study and work, and can give the healthy many losses that can't retrieve that cause.Just can provide some of the recommendations through display screen automatically in the present embodiment; As " physical training can obviously improve vital capacity; for example can be regular do some chest expandings, free-standing exercise exercise such as raise one's arm; adhere to durable race, swim, play soccer, play basketball, turning back run etc., can reach more than 6000 milliliters as middle-distance runner and swimmer's vital capacity.That a kind of method of selection it should be noted that no matter all will persevere doing constant practice ability effectively.Because physical training can obviously increase the strength of respiratory muscle, improve the elasticity of lung, the degree of depth of breathing is strengthened, deepen, improve and improve the efficient and the function of pulmonary respiration ".

Wherein, said distance detection device is the infrared distance measuring pick off.Said data storage device can be a memorizer.The portable terminal of present embodiment can be mobile phone.

Have the operation principle of the portable terminal of vital capacity measuring ability based on the foregoing description, the embodiment of the invention also provides a kind of portable terminal vital capacity detection method with vital capacity measuring ability, and as shown in Figure 2, it mainly may further comprise the steps:
