An embodiment of the present invention provides a method for measuring lung capacity, as shown in fig. 1, the method includes:
101. and receiving a gas voltage signal, and converting the gas voltage signal into a digital signal.
Wherein, gas voltage signal is for the voltage signal that will acquire the gas flow rate through the pressure sensor of chip form, the gas flow rate is the gas that the user passed through the mouthpiece exhalation, and the process buffer spreads into to pressure sensor in to the realization converts the gas flow rate into gas voltage signal, measures the numerical value of vital capacity to the gas flow rate promptly. In addition, in order to monitor and process the gas voltage signal, the gas voltage signal needs to be converted into a digital signal.
It should be noted that the principle of converting the gas flow rate into the gas pressure signal in the embodiment of the present invention is to use a fluid mechanics principle equation:
wherein Q is total gas flow, s is the sectional area of the test tube, V is gas flow rate, P is pressure, K is a constant coefficient, t1,t2To measure time. Wherein
The integral summation can be achieved by accumulating the data a number of times, p being measured by the pressure sensor.
In addition, in order to improve the utilization efficiency of the vital capacity measuring method of the embodiment, in the corresponding hardware device, the configured pressure sensor is a pressure sensor in the form of a chip, such as an XGZP6847 gas pressure sensor, the chip adopts a DIP package form, the pressure sensor is integrated with a digital conditioning chip as a sensitive element, the two sides of the PCB are respectively provided with the SOP-packaged pressure sensor and a signal processing circuit chip, and zero point offset, temperature drift, sensitivity deviation and nonlinear phenomena generated by the sensor can be digitally compensated, so that a standard voltage signal after calibration and temperature compensation is generated. The XGZP6847 model gas pressure transmitter module is small in size and easy to install, and can calibrate an output signal according to user requirements. In this embodiment, the XGZP6847 may be used to provide a relatively accurate high-level analog output voltage signal proportional to the measured pressure, and then transmit the data to the single chip for processing and conversion.
102. And monitoring the state information of the digital signal through a microprocessor, and sending voice prompt information to a voice broadcast device or sending alarm information to a buzzer according to the state information.
The state information includes initial information, process information, and end information, where the initial information is a voltage value of initial insufflation gas, which is generally 0, when a user performs a spirometry, and the voltage value may have a value other than 0 only in a case where the user does not perform a reset. The process information is a voltage value that gradually changes with the gas flow rate, and the end information is a voltage value at which the gas flow rate stops changing, so that the total change value of the gas flow rate, that is, the value of the vital capacity can be calculated from the state information.
It should be noted that, in the embodiment of the present invention, in order to enable a user to grasp the situation of the vital capacity at any time, when the state information changes at any time, a prompt is sent by using a voice broadcaster or a buzzer according to different state information, for example, when the start information and the process information are monitored, in order to inform the user of the current state of the vital capacity measurement, the voice broadcaster may be used to broadcast the voice prompt information, and when the end information is monitored, in order to prompt the user to end the measurement, an alarm is sent by using the buzzer.

In order to avoid the interruption of the gas flow rate during the process of measuring the vital capacity by the user, it is necessary to analyze whether the voltage signal in the process information is a continuously incremented voltage value, so as to monitor the voltage value as an uninterrupted voltage increment value at any time, where the preset time interval may be 5 seconds, 10 seconds, and the like, that is, the voltage increment value in a time period is sent through the voice broadcaster every other time period, for example, every 5 seconds, the current voltage increment value in 3 seconds is broadcast through the voice broadcaster as 20, and the corresponding increased vital capacity value is 100, which is not specifically limited in the embodiment of the present invention. When the voltage signal in the analyzed terminal information is a continuously unchanged voltage value or the voltage value is 0, the fact that the user does not blow gas is indicated, the vital capacity measurement is finished, and a second alarm signal is sent to a buzzer to inform the user of the end of the measurement.
