Abstract
An alcohol test method and apparatus. The alcohol test method comprises: receiving gas exhaled by a testee from a gas channel (S101); measuring an alcohol content in the gas according to the gas exhaled by the testee from the gas channel (S102); obtaining a gas alcohol concentration value according to the measured alcohol content in the gas (S103); and calculating an output alcohol concentration value according to the gas alcohol concentration value (S104). By means of a method for conveniently measuring the alcohol concentration, the alcohol concentration of the gas exhaled by the testee can be rapidly measured.
Claims10
An alcohol test method, comprising:
- receiving gas exhaled by a testee from a gas channel;
- measuring an alcohol content in the gas according to the gas exhaled by the testee from the gas channel;
- obtaining a gas alcohol concentration value according to the measured alcohol content in the gas;
- and
- calculating an output alcohol concentration value according to the gas alcohol concentration value, wherein a measurement uncertainty coefficient is employed in calculating the output alcohol concentration value to adjust an accuracy of the output alcohol concentration value, and the measurement uncertainty coefficient varies with different alcohol concentrations.
An alcohol test apparatus, comprising:
- a receiving unit configured to receive gas exhaled by a testee from a gas channel;
- a measurement unit configured to measure an alcohol content in the gas according to the gas exhaled by the testee from the gas channel;
- a concentration calculation unit configured to obtain a gas alcohol concentration value according to the measured alcohol content in the gas;
- and
- an output unit configured to calculate an output alcohol concentration value according to the gas alcohol concentration value, wherein a measurement uncertainty coefficient is employed to adjust an accuracy of the output alcohol concentration value, and the measurement uncertainty coefficient varies with different alcohol concentrations.
