Description

Internet of Things-based smart automatic power home appliance control device and method {IoT-based smart automatic power home appliance control device and method}

The present invention relates to an IoT-based smart automatic power home appliance control apparatus and method, and more particularly, when a user transmits his/her location information to a server through an app installed in his/her terminal, the server Styler, washing machine, air purifier, robot vacuum cleaner, humidifier and dehumidifier provided in the personal living space according to the user's proximity to the personal living space by calculating the distance and arrival time from the living space (home, office, etc.) To provide a smart automatic power home appliance control device and method based on the Internet of Things by automatically operating or stopping home appliances and lighting such as electric appliances and lighting based on personal information and control information stored in advance by the user. it's about

Recently, as portable terminals such as smartphones have been expanded and distributed, they have become a necessity of modern people. Portable terminals allow access to most home appliances and lighting installed in homes or offices through the Internet anytime, anywhere. However, there is still a problem in that each individual user has to intentionally access the Internet and directly control the device or control it through complicated settings.

Therefore, by allowing the user to automatically adjust the home appliances or lighting installed in his/her personal living space according to the user's location in the process of going to work or leaving the office with the terminal in possession, control of the corresponding home appliance or lighting is improved. It can be performed efficiently, and this efficient control ultimately results in saving energy consumption. That is, the concept of optimizing the consumption of energy by efficiently using it rather than unconditionally saving energy is required.

Efficiency of energy consumption is to use as much energy as necessary and not to waste it, and ultimately, to obtain convenience as much as energy consumed. Energy conservation will eventually affect environmental problems, and it is essential to reduce unnecessary energy consumption in order to preserve the environment well.

Therefore, there will be a continuous demand for monitoring and control technology for user-centered energy efficiency to change awareness of environmental issues and to improve inefficient energy use. Due to the increasing demand for carbon reduction and energy efficiency improvement, budget reduction and low-carbon technology are needed through reduction of energy consumption in buildings, and IT technology development is necessary to meet the resulting low-carbon green growth industrial policy. In particular, a customized energy saving technology for each site, which is a site that consumes energy, is required, and an energy saving system technology in a personal space that can manage energy saving for power devices including heating and cooling, lighting, or a combination thereof is required. have.

Examples of practical application of energy saving system include building energy management based on hardware solutions including building automatic control system (software), intelligent building system (IBS), home network, video system, mobile or intelligent transportation system (ITS), etc. There is an example where the system was built and serviced, and the application of IBS to skyscrapers is being expanded in complex development projects such as U-Town. In addition, the field of energy use is divided into electricity, water, heating and cooling, lighting, electric heat or power.

We are trying to control energy facilities by finding the conditions that can achieve the maximum effect with less energy by subdividing them into three categories and analyzing them through pre-simulation based on the data collected through the monitoring function.

However, despite these efforts, in the case of large buildings, only energy management for the majority of employees is performed in summer or winter. Aggravation may also occur. This phenomenon is a side effect of not having personalized control over energy consumption.

Hereinafter, the smart automatic power home appliance control device 100 , the data collection device 300 , the data server 400 , the sensor device 500 and the home appliance 600 will be described first, and then the smart automatic power home appliance About the control device 100

Next, I would like to explain in more detail.

The user terminal 200 is at least one terminal capable of monitoring in real time the operating status of home appliances and peripheral devices installed in various facilities for each personal living space, and a PC or smart phone capable of remote monitoring by wire or wirelessly. , a tablet PC, or a combination thereof. In addition, the user terminal 200 may adjust the power used by predictive control by a predefined program, and may sequentially control the load according to the priority order. In addition, it is possible to provide an emergency notification service to the manager's mobile terminal in the event of a monitoring that can check the power usage in real time and an emergency situation, and detect the location of the user terminal 200 in real time to display the user's location information as a smart automatic power home appliance. It may be provided to the device control device 100 .

Here, the predictive control may be simple, for example, by setting a timer to operate and stop the home appliance 600 in advance, and more complicatedly according to human body detection or season, age, daytime and nighttime. Power control can be performed differently. For example, when the demand for electricity in summer is at a peak, it is possible to control to save electricity as much as possible. In addition, it is possible to block radiant heat by sequentially operating home appliances or closing curtains to block external sunlight in several managed spaces during peak times in summer when power consumption is at its peak.

all.

In addition, it is also possible to set the level of importance according to the type of home appliance 600 such as a styler, a washing machine, an air purifier, a humidifier and a dehumidifier, and to set a differential control accordingly. For example, in the case of a facility where air cleaning is important, the control of the air purifier can be prioritized over other washing machines to be controlled.

For the user terminal 200 , a user interface may be provided differently depending on the terminal, and the user interface may be provided in a customized manner according to the characteristics of the personal living space in the data server 400 . That is, when the user inputs conditions such as the type and time of the home appliance 600 to be controlled for the personal living space and sets a template designating a frame for the user interface, the data server 400 generates the user interface accordingly. to provide

At this time, each user interface does not require a separate compilation process, and is created and provided at any time upon a user's request. This defines the behavior of each part including the menu, button, and input window constituting the user interface frame and maps them to implement the desired user interface. There are several types of these frames and

When provided to the user as a fleet, the user designates a desired template, and when the data server 400 is notified, the data server 400 prepares and provides a user interface with the template selected by the user. In addition, when the user terminal 200 is a mobile terminal, the mobile terminal uses a GPS device, WiFi, Zigbee, Bluetooth, and a beacon signal provided therein to obtain the current location information of the user terminal 200 . It may be transmitted to the smart automatic power home appliance control device 100 in real time.

In addition, the user terminal 200 supports a mobile web app based on HTML5, and can transmit location information and setting information to the data server 400 by executing the web app independently on the OS or device of the user terminal 200 . have.

The data collection device 300 can remotely control the home appliance 600 including a styler, a washing machine, an air purifier, a robot cleaner, a humidifier, a dehumidifier, or a combination thereof through an individual sensor device 500 or a smart integrated sensor node. It is a device that collects and transmits environmental information. The data collection device 300 can collect data directly from various environmental sensor devices 500 including temperature, humidity, air pollution, CO2 or fire sensors or from a smart integrated sensor node using low-power wireless communication (Zigbee). have. In particular, it includes a gateway function for interworking with the smart automatic power home appliance control device 100 capable of monitoring the state of an air purifier or humidifier through the Internet or a mobile communication network.

The data server 400 controls the home appliance 600 based on environmental information including temperature, humidity, illuminance, air pollution level, or a combination thereof for each location of the sensor device for each site, thereby providing the optimal solution required for each site. It is equipped with intelligent middleware that allows it to be operated as a state. It can be used conveniently by linking the sensor device (including video camera) installed to monitor the indoor condition of each site and the user operating program (the operation scenario of each space created according to the user's requirements). This is especially true for personal life. It is possible to name the middleware applicable to space, etc., and to install and operate it in the data server 400 .

The intelligent middleware receives the usage conditions of the site from the user so that the smart automatic power home appliance control device 100 operates as the user wants, and once the user specifies various usage conditions for the operation of the site Accordingly, the data server 400 provides an operation scenario of the corresponding space, and the corresponding space is controlled accordingly. Of course, it is also possible to designate a priority for the control of the home appliance 600 in the conditions of use, and the conditions can be variously designated according to time, place, season, user, or a combination thereof.

The designation of the conditions can be performed through the monitoring user interface of the user terminal 200 or the app of the smartphone, and it is also possible to input a control operation as well as monitoring through the user interface.

In particular, the designation of conditions for each user may be based on the user's personal information first, but in the present invention, it is preferable to perform the control operation based on the setting information previously set by the user.

In other words, intelligent middleware includes a site management function, a sensor abstraction function, a sensor information management function, a conditional information management function, a spatial information filtering capability, a situational recognition function, a situational judgment normalization function, and the like.

First, the site management function refers to a function to manage sensor information of multiple sites, the sensor abstraction function refers to a function to summarize and manage sensor information of the same type and the same condition, and the sensor information management function registers various sensor information and perform management functions. In addition, the condition information management function operates the condition information input device,

Conditional information is input based on the Conditional Data Markup Language (CDML), and the information target is an abstract sensor, group unit, and the condition information is composed of period type, target type, and value type. In addition, the spatial information filtering capability analyzes the sensing data arriving at the same time from the data collection device to identify and provide error-prone data and non-functioning sensors.

In addition, the context-aware function refers to data processing by applying related rules according to the necessary rules for various context-aware requirements existing in each application field. The normalization function of the situation judgment generally refers to processing the situation judgment conclusion as a result of normalizing it, although it is very subjective and diverse. This allows the ability to drive connected devices via SMS, ARS processing, and data collection devices (gateways).

Here, the data collection device 300 and the data server 400 can be configured to be integrated into any one, and in the present invention, for convenience of explanation, the data collection device 300 and the data server 400 are integrated. to data collection server

let it be named

The sensor device 500 may detect environmental information including human body detection, temperature, illuminance, humidity, air pollution, CO2, or a combination thereof, and may transmit various kinds of detected environmental information to the data collection device 300 at this time. Such a sensor device may transmit in the form of digital data to the data collection device 300 through Zigbee, RFID or NFC, or directly convert a signal sensed by the sensor device to digital, or directly transmit it in the form of an analog signal. . The detection signal transmitted as an analog signal must be converted to digital in the data collection device 300 and collected. Therefore, it is preferable that the sensor device 500 converts the analog detection signal into digital data and then transmits it to the data collection device 300 through a short-range communication (NFC) means.

Next, the home appliance 600 is a styler, a washing machine, an air purifier, a robot cleaner, a humidifier, a dehumidifier, or a combination thereof, and the home appliance 600 is controlled by the smart automatic power home appliance control device 100 .

And it is more preferable that the IoT-based smart automatic power home appliance control device of the present invention is applied to the environment of a personal living space including a home, an office, or a combination thereof.

In addition, when the user having the user terminal 200 approaches the personal living space, the user terminal 200 periodically transmits location information, so that it is provided inside the personal living space according to the degree of proximity to the personal living space. Home appliances such as stylers, washing machines, air purifiers, robot vacuums, humidifiers and dehumidifiers and lighting can be operated separately.

In addition, the smart automatic power home appliance control device 100 can build a database by normalizing the device information and environmental information of various home appliances 600, and has a built-in touch screen that provides context-aware control through an inference engine. is a control device. The smart automatic power home appliance control device 100 can control home appliances installed in various facilities, including stylers, washing machines, air purifiers, robot cleaners, humidifiers, dehumidifiers, or combinations thereof, which are commonly used at home. The normalization refers to the process of increasing the storage efficiency by removing overlap between the device information and the environmental information of various home appliances 600, which is related to the maintenance and management of consistent information between the specific environmental control device and the environmental information.

This is a necessary process for Lee. Here, the home appliance 600 refers to home appliances such as a styler, a washing machine, a robot cleaner, a humidifier, a dehumidifier, and an air purifier that are commonly used in personal living spaces.

This home appliance 600 can maintain a comfortable and comfortable indoor environment of the personal living space through remote control using the user terminal 200, and the time it takes for the user to drive the home appliance 600 in the personal living space can save

To this end, environmental information of the personal living space can be collected from the sensor device 500, and the environmental information varies according to the external temperature or weather according to the time of day and night according to the season, so not only the internal environment but also the external environment. It may also include information about the environment.

Since the internal environment has a sensitive effect on the control of the home appliance 600, real-time measurement results are used, and information on the external environment may be preset or designated as weather information or setting of sunrise and sunset times. In addition, the user may set and store user personal information such as the user's body temperature and health condition using the user terminal 200 .

In order to apply this environmental information to the actual home appliance 600, personal information and personal location tracking are used in the customized smart automatic power home appliance power control device 100. Data processing for use as meaningful information in the control device This is called the normalization process. For example, when a specific measurement value is collected from an air pollution sensor and input, it may be necessary to divide the air pollution value into several grades so as to be suitable for use in the control device. In addition, even in the case of human body detection, when a certain person's body temperature is sensed and the home appliance 600 is controlled therefrom, it is necessary to define the indoor environment according to the number of people from which the human body detection result is sensed.

The reasoning engine is a process for executing an algorithm for deriving an appropriate control value of the home appliance 600 based on the environmental information measured and collected from the sensor device 500, and in the present invention, the measured data collected by the inference is set to a threshold After defining the degree of controlling each home appliance 600 when it is within and exceeding the range of the threshold value compared with the value, the home appliance 600 is continuously compared with the real-time measured value of the environment information with the threshold value Derive a control value of (600). In this case, the threshold value is determined by utilizing weather information and season information including temperature, weather, wind or wind speed in addition to the measured values from the sensor device 500 for the indoor environment.

In addition, the environmental information including weather information, season information, or measured indoor temperature and the control value of the home appliance 600 are stored in the database, and the mapping relationship between them is always updated, so that a more accurate control value can be derived. It is controlled so that it can be customized and adapted to each space. This is because the state of each individual living space is completely different, and it is meaningless to derive a uniform control value from it. This is a so-called heuristic control method.

That is, even when the user of the personal living space operates the home appliance 600 , it is possible to detect the contents of the corresponding control to determine what kind of environment a person who actually uses the corresponding personal living space wants. These results are used as an empirical rule to control the corresponding used space.

Through the control method, a more sophisticated and efficient control result can be achieved by eventually controlling the home appliance 600 by recognizing the situation of the corresponding personal living space as close to the actual environment as possible.

In addition, the smart automatic power home appliance control device 100 can individually control each home appliance 600 according to the location information of the user terminal 200 and the control information of the home appliance 600 from the data server 400 . may be

Hereinafter, when a user gradually approaches a personal living space such as a personal office or studio with a mobile terminal, how far away the user is from the personal living space In addition, as the user moves away from the personal living space, the process of performing automatic power home appliance control so as to block the operation of the home appliance step by step will be described in more detail.

In this case, the location information may be the current location of the user, and the control information may be the operation state information and the expected driving time of the home appliance 600 in the personal living space, such as a home or office, which is a personal living space.

Accordingly, the user terminal 200 of the present invention may perform the Internet of Things to perform communication between each home appliance 600 and the user terminal 200 .

The Internet of Things (IoT) is a technology that connects to the Internet by embedding sensors and communication functions in various objects. Things connected to the Internet of Things should have a unique IP that can identify themselves and be connected to the Internet, and sensors may be embedded to acquire data from the external environment.

On the other hand, the user terminal 200 sets the personal information location information and control information set by the user. In addition, it is possible to remotely control the home appliance 600 provided in the personal living space through the user terminal 200 . In addition, when the user has the user terminal 200 and is adjacent to an office, house, inside a vehicle, or any personal living space including these, the styler, washing machine, and air Devices such as a purifier, a robot vacuum cleaner, and a humidifier operate individually to set a personal living space in a state set by the user.

Thereafter, a list of home appliances provided in the personal living space may be output, and the user may operate a desired home appliance by selecting or touching each list. In addition, when the user selects the humidifier from the list of home appliances, the operating state of the humidifier is output, and the expected time of arrival of the user to the personal living space and the operating time of the humidifier may be output and provided to the user. In addition, an operation cancel selection area is provided to turn off the power of the humidifier in operation.
