Description

Smart home air-care system by use of blockchain-based shared processing of information of fine dusts}

The present invention relates to a technology for managing indoor air quality by controlling a ventilation system according to fine dust information.

In particular, the present invention shares a number of fine dust measurement information through a block chain within a living environment cluster that is geographically close and exposed to a uniform fine dust environment, so that the smart home terminal device accurately acquires the outdoor fine dust concentration and The present invention relates to a smart foam air management system that manages indoor air quality by interlocking ventilation systems and provides air quality management services by interlocking with other devices such as fine dust home appliances and artificial intelligence speakers.

Recently, as fine dust and yellow dust intensify, interest in air quality among living environments is increasing. In general, indoor spaces in the house are contaminated by harmful substances such as radon emitted from the cement of the wall, volatile organic compounds (TVOC) emitted from paints or adhesives, and fine particles generated during the cooking process. It is known that the most effective solution is to open a window or bring outside air into the room through the building ventilation system.

However, on days when the outside air is not clear, especially on days when the fine dust concentration is high, ventilation can be rather harmful to health. Fine dust is very small in size and does not filter through the bronchi, but penetrates deep into the alveoli, causing very serious respiratory diseases such as pneumonia and lung cancer.

Accordingly, it has become common sense that when trying to ventilate indoor air, it is necessary to determine whether to ventilate after checking the concentration of fine dust in the atmosphere through the Internet or a weather application on a smartphone just before that. However, maintaining such attention every time is quite difficult, sometimes mistakes are made, and it is sometimes difficult to determine what to do if the concentration of fine dust in the atmosphere is ambiguous.

Moreover, the concentration of fine dust in the atmosphere provided through the Internet or the weather application on a smartphone is also incomplete for practical use. The actual atmospheric environment around where the residents are located may be worse or better than the ones checked on the Internet or smartphone. While there are currently only a few hundred official air quality measurement facilities across the country, the concentration of fine dust in the atmosphere shows a significant difference even at a slight distance, so even if the information on fine dust provided through the Internet or smartphone is a reference level, the number is completely reliable.

Hereinafter, the present invention will be described in detail with reference to the drawings.

[Fig. 1] is a diagram showing an embodiment of a living environment cluster in the present invention.

In the present invention, the concept of a life environment cluster is used, which means an area that provides a substantially uniform outdoor air quality. In general, the concentration of atmospheric fine dust shows a significant difference even at distances of several kilometers to a short distance, depending on the presence or absence of reservoirs, roads, hills, roads, etc. and the direction of the wind.

Accordingly, the present invention proposes the concept of a spatial range in which the outdoor air quality is considered to be substantially uniform in everyday life, although it cannot be completely the same, and this is referred to as a'living environment cluster' in more detail.

[Fig. 1] shows a case in which a living environment cluster is set for each apartment complex as an embodiment of a living environment cluster. In general, for individual apartment complexes, it is not unreasonable to assume that the outdoor air quality is substantially uniform. Depending on the implementation example, a living environment cluster may be set by grouping a plurality of apartment complexes, or conversely, a plurality of living environment clusters may be set within one apartment complex. In setting the living environment cluster, a communication network topology configuration of a service provider providing a service to which the present invention is applied may be considered, and in this case, it is advantageous to set the living environment cluster in an individual complex.

As described later, in the present invention, a number of sensor devices for measuring the concentration of fine dust are installed outdoors, and they are grouped into a block chain in a living environment cluster unit, and their measurement information is shared in the form of a distributed ledger of the block chain. Perform a collective correction of the measured values. To enable such group correction, the concept of a living environment cluster in which outdoor air quality is substantially uniform is required.

[Fig. 2] is a diagram conceptually showing the overall configuration of a block chain-based smart home air management system according to the present invention.

In the present invention, the smart home air management system is a technology for managing indoor air quality where people spend a lot of time.In order to reduce human intervention as much as possible, the indoor ventilation is controlled by comparing and analyzing the indoor and outdoor atmospheric environments. It automatically controls the intensity of operation of the lamp. At this time, in order to accurately find out the outdoor atmospheric environment, the present invention utilizes a blockchain.

To this end, the smart home air management system according to the present invention includes a plurality of outdoor fine dust measuring devices 100 for measuring the concentration of fine dust outside a building, and a smart home terminal device for managing the indoor air quality of individual subscribers' houses ( 200), the building ventilation system 300 performing indoor ventilation opening and closing for individual subscribers' houses, the fine dust household appliance 400 performing the air cleaning function for the corresponding indoor space, and a user interface related to indoor air quality management. It is configured to include an artificial intelligence speaker 500 and a smart terminal 600 for performing, a living environment evaluation server 700 for managing outdoor fine dust concentration information for a plurality of areas.

First, the fine dust outdoor measuring device 100 is a device installed outdoors of a plurality of subscribers' houses and measuring the concentration of outdoor fine dust around each of them through fine dust sensors. At this time, the housing is not limited to an apartment or detached house, but also includes an office building or a school.

In the present invention, a group of outdoor fine dust measuring devices 100 constitute a block chain. Specifically, as described above with reference to [Fig. 1], a plurality of fine dust outdoor measurement devices 100 disposed in a living environment cluster that is geographically close and exposed to a uniform outdoor atmospheric environment Make up. It is not possible to know in detail the atmospheric environment in which each of the fine dust outdoor measuring devices 100 is placed. However, since it is estimated that the fine dust outdoor measuring devices 100 belonging to one living environment cluster are exposed to a uniform outdoor atmospheric environment, it is expected that the fine dust concentration will also measure a similar value.

The outdoor fine dust measurement devices 100 perform block chain updates according to a preset schedule (e.g., every 1 hour) and use the measured value of the outdoor fine dust concentration each generated in the corresponding block chain update cycle to the environmental information distribution ledger. Commit to (800). Through this, each outdoor fine dust measuring device 100 periodically measures the outdoor fine dust concentration (e.g., once every 10 minutes) and then acquires it in a certain time unit (e.g., 1 hour unit) in the time interval. One outdoor fine dust concentration measurement is shared.

Blockchain generally has the concept of a public digital transaction ledger in which transaction information generated on a network is duplicated and stored distributedly as many as the number of nodes shared among network participants. Blockchain technology is actively applied around cryptocurrency.In the present invention, blockchain technology is used to distribute and manage outdoor fine dust measurement information generated in a living environment cluster, and for this purpose, a number of outdoor fine dust measurement The device 100 and the smart home terminal device 200 participate in the digital ledger management of the blockchain as a kind of peer. The environmental information distributed ledger 800 is a form in which a number of transaction data are each configured like a block and connected to each other.A block is a block chain in which peers linking to the blockchain in the corresponding blockchain update cycle (e.g., 1 hour) Corresponds to the collection of created data packages. Due to the nature of the blockchain, which is based on a distributed network, data once entered in the distributed ledger 800 of environmental information cannot be modified without permission, so it is reliable.

On the other hand, the operating power of the outdoor fine dust measuring apparatus 100 may be supplied through a battery or a power cable, but it is preferable for installation efficiency to be configured to independently produce itself through a solar power generation module.

In addition, the outdoor fine dust measurement device 100 needs to be connected to an external network to perform a block chain update, and for this purpose, a short-range communication module (eg, a Bluetooth module) is provided. Considering the installation environment, since it is difficult for the fine dust outdoor measurement device 100 to have a broadband network connection function, it is connected to the smart home terminal device 200 installed indoors of the same house through a short-range communication module, and the smart home terminal device ( 200) to utilize the broadband communication function.

The smart home terminal device 200 is installed indoors of an individual subscriber's house, measures the indoor air quality of the subscriber's house through an air quality sensor, compares it with outdoor fine dust concentration information, and analyzes the indoor air of the corresponding subscriber house according to the result. It is a device that generates ventilation control information for management. For example, the smart home terminal device 200 may be implemented in the form of a set-top box or a wall pad.

The smart home terminal device 200 shares the environment information distributed ledger 800 by performing a block chain update according to a preset schedule (e.g., every 1 hour), by analyzing the environment information distributed ledger 800 A plurality of outdoor fine dust measurement devices 100 belonging to an environmental cluster may obtain measurement values of a plurality of outdoor fine dust concentrations generated in a corresponding blockchain update period (eg, during the last hour).

Since the living environment cluster is exposed to a uniform outdoor atmospheric environment, in theory, the fine dust outdoor measuring devices 100 belonging to the same living environment cluster should generate similar fine dust concentrations. However, since the fine dust sensors usable in the actual industry show considerable deviations in the measured values of fine dust according to temperature, humidity, wind speed and wind direction, the reliability of the measured values is considerably low. That is, due to the external environment, the fine dust sensors measure that the concentration of the fine dust is much lower than that of the real thing, or conversely, the concentration of the fine dust is much higher than that of the actual one.

Accordingly, the smart home terminal device 200 does not rely only on the measured value of the outdoor fine dust concentration generated by the fine dust outdoor measurement device 100 installed in matching with itself in the corresponding subscriber's house, but to the corresponding living environment cluster through a block chain. Consider a number of measurement values generated by the plurality of outdoor fine dust measurement devices 100 belonging to.

For example, in [Fig. 2], the smart home terminal device 200 is installed indoors in 3 building 2202 of a specific apartment, and the fine dust indoor measuring device 100 installed outdoors in 3 building 2202 connected to itself by Bluetooth. It is also possible to perform indoor ventilation of 3 building 2202 by receiving the measured value of the outdoor fine dust concentration from ). However, in the present invention, it is considered that it is difficult to trust the measured value of the outdoor fine dust concentration provided by the indoor fine dust measuring apparatus 100 installed outdoors in Building 3, No. 2202. Accordingly, a number of outdoor fine dust measurement devices 100 belonging to the corresponding living environment cluster, that is, outdoor measurement of fine dust installed in the same apartment complex, such as 1 building 1201, 2 building 704, 3 building 501, 3 building 2202, etc. The devices 100 receive and comprehensively deal with the outdoor fine dust concentration measured at the same time through the blockchain.

The smart home terminal device 200 calculates an estimated value of the outdoor fine dust concentration based on the measured values of the plurality of outdoor fine dust concentrations obtained through the blockchain. For example, it is possible to calculate an estimated value by calculating an average value for a plurality of measured values. Through this, an effect of collectively correcting measurement errors caused by external factors in each of the outdoor fine dust measuring apparatuses 100 is obtained.

Then, the smart home terminal device 200 generates ventilation control information for indoor air management of the subscriber's house according to the result of comparing and analyzing the indoor air quality measured by itself and the estimated value of the calculated outdoor fine dust concentration. . Indoor ventilation is performed according to the ventilation control information, and the air conditioner installed in the building is driven, the window switch is opened, or the air purifier is operated. At this time, it is possible to adjust whether or not to drive, intensity, and operating time in response to the ventilation control information.

The building ventilation system 300 is a device installed in an individual subscriber's house to open and close indoor ventilation, and may be a device installed in a building unit or a device installed in an individual unit. For example, a ventilation duct system, an air conditioner, and a window opening and closing device may be mentioned. The building ventilation system 300 according to the present invention is connected to the smart home terminal device 200 by wired or wirelessly, and performs indoor ventilation opening and closing in response to the ventilation control information generated by the smart home terminal device 200.

The fine dust household appliance 400 is a household appliance that cleans the air in the surrounding room in which it is placed, and may be implemented in the form of, for example, an air purifier. The fine dust household appliance 400 according to the present invention has a fine dust filtering member therein to perform indoor air cleaning, and is wirelessly connected to the smart home terminal device 200 (for example, Bluetooth), and the smart home terminal device ( In response to the ventilation control information generated by 200), the fine dust filtering operation on and off and the filtering operation intensity are controlled.

The artificial intelligence speaker 500 is a speaker device that exchanges queries and responses based on artificial intelligence using voices with subscribers, such as KT GiGA Genie, SKT NUGU, Google Assistant, Amazon Alexa, and the like. The artificial intelligence speaker 500 according to the present invention is wirelessly connected to the smart home terminal device 200 to receive the measured value of indoor air quality and the estimated value of the outdoor fine dust concentration, and store it in the interior temporarily or for a considerable period of time. When a voice inquiry is received, a voice response is provided.

To this end, when receiving a voice query from a subscriber, the artificial intelligence speaker 500 analyzes the voice query by interworking with an external AI service server. As a result of the voice query analysis, if the content of the voice query is normal, the response data provided from the AI service server is output as voice. On the other hand, as a result of the voice query analysis, if the voice query content relates to the ambient air quality, the measured value of the indoor air quality or the estimated value of the outdoor fine dust concentration is output as a voice in response to the voice query content.

The smart terminal 600 refers to a general smart phone or a tablet PC, and an environment management application interworking with the present invention is installed. The environment management application installed in the smart terminal 600 is wirelessly connected to the smart home terminal device 200 to receive indoor and outdoor air quality status and ventilation control information, and display it on the terminal screen, and a user manipulation input is displayed on the smart home terminal device 200. To be reflected in indoor ventilation control. In addition, by accessing the living environment evaluation server 700 via a wireless LAN or a mobile communication network, various types of information are provided and displayed.

The living environment evaluation server 700 continuously receives an estimated value of the outdoor fine dust concentration calculated from a plurality of smart home terminal devices 200 installed indoors of a plurality of subscribers' houses, and then divides it into a living environment cluster unit. Manage. Through this, it is possible to estimate the outdoor fine dust concentration in a living environment cluster unit, for example, in an apartment complex unit. In addition, in response to requests from external devices (eg, smartphones, computers, portal service servers), a service is implemented that provides information on the estimated value of the outdoor fine dust concentration for each living environment cluster.

[Fig. 3] is a diagram conceptually showing an example of a data structure input to a block chain in the present invention.

First, the outdoor fine dust measuring apparatus 100 measures the concentration of outdoor fine dust at a point where each of them is installed, and the related information is packaged and put into the blockchain. As an example, a'outdoor measurement device IP address' field that is identification information about who it is, a'outdoor measurement time' field indicating the time of fine dust measurement, and a'outdoor fine dust measurement value' field indicating the fine dust measurement result , And a'smart home terminal IP address' field indicating a path through which the information is transmitted.

Since the block chain is composed of a living environment cluster unit, the result of measuring the concentration of outdoor fine dust performed by a plurality of outdoor fine dust measuring devices 100 installed in the corresponding living environment cluster is input and collected in one block chain. do. Since the blockchain update is performed in a certain time unit, for example, every 1 hour, the information is distributed and shared to all devices belonging to the living environment cluster when the result of measuring the outdoor fine dust concentration is over a certain period of time.

The smart home terminal device 200 obtains the measurement result of the outdoor fine dust concentration that the plurality of outdoor fine dust measurement devices 100 put into the block chain in the previous block chain update cycle through the block chain, [Fig. 2 As described above, the obtained information is used for indoor ventilation control of the corresponding subscriber's house. In addition, in terms of information management of indoor ventilation control, the smart home terminal device 200 also packages data related to itself, such as its own IP address, indoor air quality measurement time, and indoor air quality measurement value, to the blockchain. Can be configured to put in.
