Recently, the effect on the human body due to the deterioration of air quality, which is getting worse due to fine dust and other pollutants, has been highlighted recently.

In addition, in order to minimize contact with the air due to outdoor activities, the interest in indoor air quality is increasing due to the restriction of living space such as work space or refraining from going out.

In order to purify indoor air, various devices for improving air quality have been developed, but the development has been biased toward air quality improvement devices suitable for general office or residential spaces.

A general office space or residential space forms an open space to allow the flow of air that is naturally introduced from the outside, whereas a ship forms a closed space to prevent the inflow of low-temperature air or seawater in extreme cold areas, and Since the inflow is made forcibly, it is not easy to apply the previously developed air quality improvement device.

In particular, a duct, which is an air passage formed in the upper part of the cabin, is used so that the inflow of outside air is made. There was a problem of contaminating other cabins by the circulating duct.

In recent years, there is an urgent need for technology development for a method that can easily perform this along with the demand for a method to improve the air quality of the cabin.

In addition, the duct has an external inlet through which air is introduced from the outside; It is installed in parallel with the outer inlet and is formed of a circulation port through which air is introduced from the cabin; and a supply port through which air is supplied to the cabin. It is a technical feature to be supplied.

In addition, the sensor unit and the purification unit are separately installed in each cabin, and the control unit is installed in a single unit in the integrated control room to control the control of the sensor unit and the purification unit in an integrated manner.

In addition, the purifying unit is detachably installed in the supply port, and a UV lamp and a photocatalytic filter are technically characterized.

In addition, there is provided a method for improving air quality using a smart air purifying device for a cabin, comprising: an outside air inflow step of introducing air from the outside through the outside inlet; a circulating air inlet step in which air is introduced from the cabin through the circulating port at the same time as the outside air inlet step; a sterilizing air supply step of sterilizing the air supplied to the duct in the outside air inlet step and the circulating air inlet step through the sterilization device and supplying air to each cabin through the supply port; a measuring step of measuring fine dust and air components of the air supplied in the air supply step using the sensor unit installed in each cabin; a transmitting step in which the measured value obtained in the measuring step is transmitted to the control unit; a matching step in which the measured value received in the transmitting step is matched with the purification unit installed in each cabin; a screening step performed simultaneously with the matching step, in which cabins requiring air quality improvement are selected using the measurement values received in the transmitting step; A solution deriving step in which the air quality improvement solution of the cabin selected in the screening step is derived; and a control step in which the solution obtained in the solution deriving step is performed by the purification unit matched in the matching step.

The present invention according to the above configuration can expect the following effects.

In the case of a very large ship, the number of cabins is very large, but the present invention can minimize the effect on the human body of the crew boarding the ship because it can be managed in an integrated manner.

In particular, in the case of ships, in that the cabin is very simplified and miniaturized to accommodate the maximum amount of cargo or manpower in a limited space, the effect on the human body from the air quality in the cabin is large, so the effect will be greater. .

Conventionally, as the air supplied through the duct is supplied to the cabin at once, air pollution on one side may cause a chain reaction that causes air pollution on the other side, but by the sensor unit and the purification unit provided for each cabin Appropriate measures can be taken for each cabin, so that air quality can be improved quickly and effectively.

The air supplied through the duct is first sterilized to purify the air, and then the air quality can be easily improved by performing the air purification according to the situation for each cabin.

The smart air purification apparatus for a cabin according to a preferred embodiment of the present invention consists of a duct 100 , a sensor unit 200 , a control unit 300 , and a purification unit 400 as shown in FIG. 1 .

First, look at the duct 100.

The duct 100 generally refers to a hollow pipe to which a fluid is supplied, and may be a generic term for the entire outdoor air supply pipe for supplying outdoor air to the cabin.

The duct 100 may be made of various materials, but considering that it is a ship, it is made of a metal material, but considering that air is supplied to the cabin via this, stainless steel or aluminum material with a low possibility of corrosion or contamination It may be preferable to consist of

In general, the configuration of the duct 100 may be buried or buried in the upper part of the ceiling of the cabin. In detail, an outer inlet 110 through which air is introduced from the outside, and a circulation port 130 through which air is introduced and circulated from the cabin are formed on one side, and the air introduced into the outer inlet 110 and the circulation port 130 is formed on one side. A main line is formed so as to move to a position close to each cabin, and air can be introduced through the supply port 150 formed in each cabin by branching from the main line to each cabin.

The supply port 150 formed in each cabin is formed in the upper part of the cabin, so it may be preferable to let the introduced air fall from the upper part to the lower part.

The air introduced into the cabin can be circulated by the circulation system. Simply, the air inside the cabin is discharged from the cabin through the vent formed in the cabin and flows back into the duct 100, but the above-described circulation port 130 It may be a circulation system to be introduced through the

As described above, the duct 100 is provided with an external inlet 110 and a circulation port 130 on the side where air is introduced, and is provided in the cabin so that the air introduced into the external inlet 110 and the circulation port 130 is supplied. A supply port 150 may be formed on the shaft formed in contact.

A sterilizer 170 may be further provided between the external inlet 110 and the circulation port 130 and the supply port 150 .

In detail, the air introduced into the outer inlet 110 and the circulation port 130 is merged and mixed in the main line. Air introduced into the sphere 130 may be primarily purified by sterilization.

The sterilized air may be branched from the main line and supplied to each cabin through the supply port 150 , and the air supplied to the cabin may be secondarily purified by a purification unit 400 to be described later.

The sterilization device 170 may be anything by heat or using ultraviolet rays and a photocatalyst.

Next, look at the sensor unit 200 .

A sensor, which detects certain elements, generally means to sense a physical change such as a position or speed, but here it can be collectively referred to as sensing a component of air and measuring a physical quantity thereof.

In detail, the sensor unit 200 may include a PM sensor for measuring fine dust, a CO ₂ sensor for measuring air components such as carbon dioxide or volatile organic compounds, and a Volatile Organic Compounds (VOC) sensor.

The sensor unit 200 is provided with communication means so that the measured value is transmitted accurately and easily to the control unit 300, which will be described later, and can be connected by wired or wireless communication, and can be individually installed in each cabin. can

The position of the sensor unit 200 may be located anywhere, such as the upper or lower part of the cabin, but the supply port 150 of the duct 100 is a place where the inflow of air is active for easy measurement of fine dust or air components. It may be desirable to be installed nearby, but inside the cabin.

Next, look at the control unit 300 .

The control unit 300 may play a role of receiving the measurement result data transmitted from the above-described sensor unit 200, determining whether each cabin is contaminated, and deriving a solution for air purification using this.

In addition, it is possible to determine whether to operate the sterilizer 170 and the purification unit 400 so that the derived solution can be applied, and to issue a control command to perform the operation.

In order to perform the role, the control unit 300 may be provided with a communication means for receiving measurement result data and transmitting a control command for performing a solution.

The control unit 300 may be provided for each cabin, but it may be preferable to install a single control unit in the integrated control room to perform integrated analysis of measurement result data and to individually perform solutions for each cabin.

In particular, when a plurality of cabins are provided, such as a very large ship, it is more efficient to control each cabin individually than to control each cabin individually, and for this reason, the inflow of outside air is also performed by an integrated means such as the duct 100 .

The control unit 300 has a display means, so that the measurement result data and the result of the solution derived for air purification can be visually displayed.

Additionally, the control unit 300 is connected to the user's mobile terminal (M) to communicate with each other so that the above-described measurement result data, air purification solution, and air purification state can be easily accessed without being limited to the user's location.

The control unit 300 derives an air purification solution using the received measurement result data, but it may also be possible to use big data.

The degree of contamination of each cabin may be different depending on the measurement result data. The UV lamp (not shown) and the photocatalytic filter (not shown), which are components of the purification unit 400, which will be described later, have an appropriate level according to the degree of contamination of each cabin. It can be controlled to operate with

The solution may be to derive an appropriate operating level of the purification unit 400, and additionally, to prevent the circulation of contaminated cabin air, it is determined whether the circulation port 130 is opened or closed, or Determining whether to close the external entrance 110 to prevent the inflow may also correspond to a solution.

Finally, the purification unit 400 will be examined.

The purification unit 400 may be a generic term for purifying air through removal or filtration of fine dust or harmful air components in the incoming air.

The purification unit 400 may be individually installed in each cabin, and whether or not its operation and operation level may be controlled according to the degree of pollution of each cabin.

The purification unit 400 may be detachably installed in the supply port 150 of the duct 100, and as described above, the supply port 150 is preferably located in the upper part of the cabin, so the purification unit 400 is also It may be located at the top of the cabin.

The shape of the purification unit 400 may be configured as a hollow box, and a UV lamp and a filter may be provided therein, and it may be possible to open it to facilitate replacement and inspection of internal components.

The purification unit 400 may include a communication means in order to control the execution of the solution derived from the control unit 300 .

The purification unit 400 is provided with a filtration filter for filtration of fine dust, and may serve to decompose and purify viruses or harmful gases by means of a UV lamp and a photocatalytic filter.

A method of improving air quality using the above-described components will be described.

The measurement value obtained in the measuring step (S400) may be transmitted as data to the control unit 300 by a communication means that may be provided in the sensor unit 200 in a transmitting step (S500).

As described above, the transmitting step ( S500 ) may be performed by connecting the sensor unit 200 and the control unit 300 by wire or wirelessly.

The measurement value received to the control unit 300 in the transmission step S500 may be subjected to a matching step S600 in which the measurement value is assigned to the purification unit 400 installed in each cabin within the control unit 300 .

As designating precisely which purifying unit 400 the received measured value is the measured value, it may serve to enable a solution to be derived for each cabin to be performed at an accurate point.

A selection step (S700) of determining whether pollution is present using the measured value and selecting a cabin requiring air quality improvement may be performed simultaneously with the matching step (S600).

Pollution using the measured value may be determined by a predetermined pollution determination logic, and when it is determined as pollution by the determination logic, the cabin requiring air quality improvement may be managed through screening.

A solution derivation step (S800) in which an air quality improvement solution is derived using the measured value of the cabin selected in the screening step (S700) may be performed.

The air quality improvement solution may be derived by big data analysis using a database stored in the server of the control unit 300 .

The derived solution may be to determine whether or not the purification unit 400 is operated and the operation level, and the solution to the purification unit 400 matched in the matching step ( S600 ) is controlled by the command of the control unit 300 . Air quality may be purified by step S900.

The control step ( S900 ) may be performed manually by the user or automatically performed by the control unit 300 .

The measured values obtained in each of the above steps, selection of cabins requiring air quality improvement, derived solutions, etc. may be visually shared by the control unit 300 to the user's mobile terminal M through a communication connection.

The air in the cabin whose air quality has been improved through the control step (S900) can be reintroduced into the cabin by circulation, and the method of improving the air quality described above sequentially from the circulating air introduction step (S200) can be continuously made.
