The subject of the invention is a method of remotely evaluating the alcohol content in the exhaled air, applicable for conditioning access to workplaces using a computer application. The creation of an appropriate model allows the development of a virtual assistant supporting the work of a person supervising sobriety at the workplace.
So far, methods of remote monitoring and verifying the sobriety of employees are known, including remote measurement of alcohol content in exhaled air and informing the employer about its result based on telecommunications systems, with the possibility of remotely blocking access to the workplace. Known solutions do not include technology that enables the detection of counterfeits, as well as mistakes in the identification of the person for whom the measurement is made, with the possibility of self-learning.
As part of the solution, according to the invention, a set of activities was developed, including data preparation, transformation, and analysis to create an optimal device and user identification model.
From the Canadian description of the invention CA2906116 there is known a method of monitoring sobriety by means of a handheld device for breath testing, which, after receiving the alcohol concentration value in the exhaled air, generates a signal containing data on the content of the breath.
The substance and user identification data are sent wirelessly via the cellular network to the receiving station.
The American invention US2020191769A1 discloses a method of remotely monitoring sobriety by means of wireless devices connected via a communication network, providing users with various forms of alerts in the form of electronic messages.
From another US description of the invention, US2020256848, a user sobriety monitoring system is known. The system may include a test device that generates a signal on the content of the substance. The test device may further include a mouthpiece and a user identification device. The user identification device may generate user identification data in response to the user's breath and may transmit it from the testing device to the monitoring station. The test device may further include at least one LCD screen or a light emitting diode (“LED”). At least one of the LCD screens or the LEDs may display at least one randomly generated visible identification mark.
On the other hand, from also the American description of the invention US2020388117 there is known a method of monitoring sobriety by means of a handheld breath testing device which, after receiving a user's breath, generates a signal containing the substance content data and user identification data and wirelessly transmits the signal to the receiving station, in which the breath testing device includes a fingerprint reader.
The aim of the invention is to develop a method for measuring the alcohol content in the exhaled air of users, leveling the possibility of a false and incorrect measurement as to the device and user.
Solving the problem of automatic identification according to the proposed method allows for continuous evaluation of the recognition model.
As used herein, the word control refers to verification and taking into account a factor, in this case, the factor being the level of exhaled alcohol.
