Abstract

The invention discloses a lung capacity test system based on a microphone of a mobile phone. The system comprises a microphone, a first bias circuit and a second bias circuit and a central processor. An anode of the microphone is connected with a first bias voltage power supply terminal by the first bias circuit; and a cathode of the microphone is connected with a second bias voltage power supply terminal by the second bias circuit. The anode of the microphone is connected with an ADC_MICP port of the central processor; and the cathode of the microphone is connected with an ADC_MICN port of the central processor. When testing is carried out, it is only needed for a tested person to blow at the microphone; and then the central processor can carry out analog-to-digital conversion on an analog signal received by the microphone; the volume of gas blown by the test person can be measured according to the analog signal as well as the lung capacity of the tested person is calculated; and moreover, a signal waveform chart of the lung capacity can be dynamically displayed in real time. In addition, according to the invention, scoring can be carried out on the measured lung capacity; and corresponded health prompting information is output according to the scoring result.

Description

technical field [0001] The invention relates to a mobile terminal, in particular to a lung capacity testing system based on a mobile phone microphone. Background technique [0002] As we all know, oxygen cannot be stored in the body, and people must inhale fresh air all the time, so breathing has a great impact on health. Vital capacity refers to the amount of gas that can be exhaled after one maximum inhalation and then the maximum capacity under the condition of unlimited time, which represents the maximum functional activity of the lungs at one time, and it is one of the important functional indicators reflecting the growth and development level of the human body. [0003] According to the 2000 national physique monitoring results released by the State Sports General Administration and the Ministry of Education, the vital capacity of men aged 40 to 69 dropped from 3347.2 ml to 2441.3 ml, and that of women dropped from 2362.3 ml to 1761.6 ml, a drop of 28% and 26% respecti...
