Description

{System for Analyzing Contamination and Pollution Using Edge Computing and Wearable Sensor}

The present invention relates to a pollution measuring device. Specifically, it relates to a mask device and a cloud server in which a sensor capable of wireless communication is mounted on a mask.

The wearing of protective equipment such as masks is increasing due to infectious diseases such as Corona 19, SARS, and MERS, in which the virus spreads into the air through the droplets of an infected person and infects others.

Until now, the measures for infectious diseases have been carried out by confirming the presence or absence of an outbreak only through direct specimens and isolating contacts through epidemiological investigations after confirming the outbreak.

However, as can be seen from COVID-19, the importance of precautionary measures to prevent the initial spread of infectious diseases is rapidly increasing.

Therefore, in the future, there is a need for a system capable of detecting infectious disease risks in advance through a device and system that can accurately report in real time through a virus detection device in a wide area.

In general, sensor technology for measuring pollution levels can be divided into chemical reaction through thermal reaction, analysis through fine optics such as a microscope, and analysis according to the frequency measurement result through light reflection such as LED. Among them, low-power sensing technology using an electric (LED) sensor with low power consumption and low-power data communication technology such as NFC and RFID are combined to use technologies such as pollution and virus measurement.

However, the existing method of measuring the contamination level of a mask using an LED has a disadvantage in that it is difficult to accurately measure due to temperature, moisture, droplets, etc. caused by the user's breathing, and it is impossible to determine the type of virus attached to the measurement object. In this case, only the degree of contamination of the measurement object is measured using only the characteristics of the amount of light passing through the measurement object (attenuation amount) or the frequency shift of reflected light using one light emitting element and one light receiving element corresponding to one light emitting element. This is because the method of identification is being taken.

In addition, the existing mask contamination measuring device does not provide a method for enabling tracking of potential confirmed patients using the collected information. In addition, technology such as real-time analysis and personal information security is utilized by using edge computing technology to check and manage data results through NFC such as smartphones and smart pads.
