DETAILED DESCRIPTION OF THE INVENTION

FIG. 1?is a view illustrating a configuration of an IoT software platform?100?according to an exemplary embodiment. As shown in?FIG. 1, the IoT software platform?100?includes a D-platform?110, a P-platform?120, an M-platform?130, and an S-platform?140.

The D-platform?110?refers to a software platform that is installed at an IoT device?115?side, and the P-platform?120, the M-platform?130, and the S-platform?140?refer to software platforms that are installed at a server computer side separately or altogether.

The D-platform?110, which is an abbreviation of "Device platform", may be directly installed in the IoT device?115?or installed in an IoT adaptor mounted in the IoT device?115, and may be interlocked with the P-platform?120?and the M-platform?130and also may be interlocked with a smart device through an IoT application and an IoT website.

The IoT device?115?recited herein refers to general things to which the IoT is applied (for example, a TV, a mobile phone, a refrigerator, a washing machine, a vending machine, etc.).

The IoT adaptor is mounted in the IoT device?115?and enables the IoT device?115?to use IoT communication. The IoT adaptor includes a communication module to communicate through at least one of near field communication (NFC), Wi-Fi, Ethernet, 3^rd?Generation (3G), and long term evolution (LTE), and the D-platform?110?installed in the IoT adaptor provides various functions to be able to perform IoT communication.

The P-platform?120, which is an abbreviation of "Planet platform", performs functions like managing the IoT devices?115, managing the user, monitoring the IoT devices?115, and searching for the IoT devices?115. Specifically, the P-platform?120receives information on the IoT devices?115?from an IoT service provider?10?and registers the IoT devices?115. At this time, the information on the IoT devices?115?includes a device ID, a device name, a model name, a manufacturer, location information and device state information, and includes an address which is necessary when the IoT devices are connected (for example, an IP address, MSISDN, etc.).

The P-platform?120?authenticates a user who accesses the S-platform?130?to register and download an IoT application for an IoT service. The P-platform?120?stores personal information such as ID/PW and telephone number of the user to authenticate the user.

Also, the P-platform?120?may authenticate a developer who develops and registers an IoT-related mash-up service or a service user who uses a mash-up service.

In addition, the P-platform?120?may authenticate IoT service access of an IoT service user using an application of a smart device (for example, a smartphone, a tablet, etc.).

The M-platform?130, which is an abbreviation of "Mash-up platform", communicates with the D-platform?110?and forwards a control command of the service user using the IoT application or the IoT webpage to the IoT device?115.

The M-platform?130?registers an IoT mash-up service which is developed by a mash-up service developer?60. That is, the mash-up service developer?60?develops the IoT mash-up service and registers it at the M-platform?130. At this time, the mash-up service developer?60?may develop the IoT mash-up service using an IoT open application programming interface (API) provided by an open API server?150.

The IoT devices?115?transmit data generated by them to the M-platform?130?periodically, and accordingly, the M-platform130?collects the data generated by the IoT devices?115?and stores the data as a log, such that the data is used to provide various IoT mash-up services to the service user.

Also, the M-platform?130?may charge for the use of the IoT mash-up service and may store brief information on the IoT devices?115?(for example, ID, IP address, etc.).

The S-platform?140, which is an abbreviation of "Store platform", provides an application store function of providing an IoT application for an IoT service to the service user. To achieve this, the S-platform?140?provides an application search function. The S-platform?140?may search for an IoT application with reference to the ID of the IoT device?115?for the user to use an IoT function of the IoT device?115.

To achieve this, the S-platform?140?registers an IoT application which is developed by an IoT application developer?50.

The open API server?150?manages and provides an open API related to the IoT service. Specifically, the development company of the IoT device?115?develops the open API on the IoT device?115?when manufacturing the IoT device?115, and registers and stores the relevant open API at the open API server?150. That is, the open API server?150?may register, store, and manage various open APIs on the IoT devices?115?developed by various development companies.

The open API server?150?provides the stored open API to a developer who wants to develop an IoT service-related website, a mash-up service site, and an application. Accordingly, the developers are provided with relevant open APIs by the open API server?150?when developing the IoT service-related web-site, the mash-up service site, and the application, and develop the IoT services using the open APIs.

For example, when an IoT device manufacturer registers an open API which provides state information on the IoT device115?(for example, information on whether the IoT device?115?is out of order or not) at the open API server?150, the developer may search for the open API providing the state information from the open API server?150?and use the open API, and may implement a function of inquiring about the state of the IoT device?115?in the IoT service-related website, the mash-up service site, and the IoT application.

On the other hand, the IoT service user may directly access the IoT device?115?using an IoT application downloaded into a smart device?40, which is a kind of a mobile device, and may use the IoT service. At this time, the IoT device?115?may be connected with the smart device?40?by means of relay of the M-platform?130?or may be directly connected with the smart device?40?through peer to peer (P2P) communication and may provide the IoT service. In this case, the D-platform?110?of the IoT device?115?may indirectly communicate with the IoT application of the smart device?40?by means of relay of the M-platform?130?or may directly communicate with the IoT application using P2P communication.

The IoT software platform?100?having the above-described configuration has the D-platform?110, the P-platform?120, the M-platform?130, and the S-platform interlocked with one another, and provides various IoT services.

Hereinafter, a process in which the user of the smart device?40?uses an IoT service will be explained with reference to?FIG. 2.?FIG. 2?is a flowchart to illustrate a process in which the user of the smart device?40?uses the IoT service using the smart device?40.

When the user of the smart device?40?executes an IoT browser using the smart device?40, the IoT browser accesses the P-platform?120?(S210), and the P-platform?120?performs authentication to determine whether the user of the smart device?40has an authority to use the IoT service or not (S220).

When the user of the smart device?40?is an authorized user, the P-platform?120?forwards information on IoT devices to be displayed on the IoT browser (S230), and the IoT browser lists the IoT devices forwarded from the P-platform?120?(S240).

In operation S240, the IoT devices may be listed in the form of icons on a map or in the form of a text list.

When one of the IoT devices listed in operation S240?is selected by the service user, the IoT browser forwards the ID of the selected IoT device to the P-platform?120?and receives detailed information on the selected IoT device?115?from the P-platform?120?(S250). The detailed information may be displayed on the IoT browser at a request of the user of the smart device?40.

Also, the IoT browser forwards the ID of the selected IoT device to the S-platform?140, and receives an application list regarding the selected IoT device?115?from the S-platform?140?and displays the application list (S260). The applications displayed in operation S260?are applications for controlling the selected IoT device?115?remotely and receiving a mash-up service related to the selected IoT device?115.

Next, when one of the applications listed in the application list displayed in operation S260?is selected by the service user, the IoT browser requests the selected application from the S-platform?140?and downloads the application (S270).

After that, the smart device?40?executes the application downloaded in operation S270?and controls an operation of the IoT device?115?(S280).

Specifically, the smart device?40?may execute the downloaded application, access the D-platform?110?mounted in the IoT device?115?through the M-platform?130, and then control the operation of the IoT device?115.

When the M-platform?130?is not necessary in the middle according to a service, the smart device may execute the application downloaded in operation S270, directly access the D-platform?110?mounted in the IoT device?115, and control the operation of the IoT device?115.

Also, the smart device may execute the application downloaded in operation S270?and may be provided with the IoT mash-up service by the M-platform?130.

Through the above-described process, the IoT software platform?100?has the D-platform?110, the P-platform?120, the M-platform?130, and the S-platform?140?interlocked with one another and provides the IoT service through the application.

In?FIG. 2, the smart device?40?executes the downloaded application, accesses the D-platform?110?mounted in the IoT device?115, and controls the operation of the IoT device?115, or accesses the M-platform?130?and receive the IoT mash-up service.

However, the smart device?40?may control the IoT device?115?or receive the IoT mash-up service by accessing an IoT web page for controlling the IoT device?115?and providing the IoT mash-up service, rather than using the downloaded application.

Also, in the above-described exemplary embodiment, the IoT device is selected using the IoT browser. However, the IoT device may be selected in various ways. For example, the IoT device may be searched/selected by directly inputting an ID or a name of the IoT device, or may be selected by searching for a category of the IoT device. Also, the IoT device may be selected by obtaining an ID of the IoT device from a QR code attached to the IoT device, or may be selected by obtaining the ID using short-range communication such as NFC, Zigbee, Bluetooth, etc.

Hereinafter, the above-described IoT browser will be explained in detail. The IoT browser provides a function of allowing the user to search for and select an IoT devices on a map or a list, and a function of displaying a link connected to an application corresponding to the IoT device.

FIG. 3?is a view illustrating a screen of a map-based IoT browser?300?which is displayed on a screen of the smart device40?according to an exemplary embodiment. When the IoT browser is executed in the smart device?40?by the user, the smart device?40?authenticates the user through the P-platform, receives information on the IoT devices, and displays the IoT devices on the IoT browser?300.

As shown in?FIG. 3, the IoT browser?300, which is executed in the smart device?40?and displayed on the screen, displays icons?341,?342,?343,?351,?352,?353,?361, and?362?corresponding to various IoT devices on the map. The locations of the icons indicate locations of the IoT devices. Specifically, it can be seen from?FIG. 3?that the IoT browser?300?displays icons corresponding to IoT vending machines?341,?342, and?343, IoT surveillance cameras?351,?352, and?353, and IoT thermometers?361?and?362.

Also, the IoT browser?300?may display an icon of an IoT device that is accessible and an icon of an IoT device that is inaccessible in different forms. Specifically, the IoT browser?300?may display the icon of the IoT device that is accessible in color, and may display the icon of the IoT device that is inaccessible in black and white. For example, as shown in?FIG. 3, the IoT browser?300?may display the first IoT thermometer?361?and the second IoT thermometer?362?in black and white to indicate that they are inaccessible, and may display a third IoT thermometer?363?in color to indicate that it is accessible.

The IoT browser?300?displays a current location icon?310, a list view icon?320, a favorite register icon?330, a favorite list icon?335, a search icon, and a setting icon?380. The current location icon?310?is an icon that performs a function of moving to a current location of the user on the map.

The list view icon?320?performs a function of converting the IoT browser?300?from a map-based mode into a list-based mode. When the list view icon?320?is selected, the IoT browser?300?displays the IoT devices currently displayed on the screen in the form of a list.

The favorite register icon?330?is displayed in the shape of a star and performs a function of allowing the user to register a location currently displayed on the map or a currently selected IoT device?115?as a favorite. That is, when the map is displayed and the user selects the favorite register icon?330, the IoT browser?300?registers a center area of the currently displayed map as a favorite.

Also, when information on the IoT device?115?is displayed and the user selects the favorite register icon?330, the IoT browser?300?registers the IoT device?115?as a favorite.

The favorite list icon?335?displays a favorite list which is a list of IoT devices or locations that are set as favorites by the user. Specifically, when the favorite list icon?335?are selected, the IoT browser?300?displays the favorite list in the form of a pop-up window.

The setting icon?380?displays a setting screen for adjusting various setting values of the IoT browser?300. The IoT browser300?may display menus to set a base map, a user ID, a user password, whether to display only an activated IoT device or not, a search term tag, a number of IoT devices that are displayed on a single screen, etc. on the setting screen.

As described above, the IoT browser?300?displays icons of various functions on the screen.

Also, the IoT browser?300?may be displayed in a different layout according to a resolution of the smart device?40. Also, the IoT browser?300?may be configured using the base map set by the user (for example, one of Daum Map, Naver Map, and Google Map).

Also, the IoT browser?300?may select a map area to be initially displayed in various methods. The first method is receiving initial area setting information on a map area to be initially displayed from the P-platform?120?and determining the map area to be initially displayed according to the received initial area setting information. The second method is displaying the area that was displayed last as a map area to be initially displayed. The third method is displaying a current location of the user as a map area to be initially displayed.

As described above, the IoT browser?300?may display a variety of IoT devices based on the map, and, when a specific IoT device is selected, may display a list of applications corresponding to the selected IoT device, and may download and install an application.

Hereinafter, two methods for executing the IoT browser?300?will be explained. When the user selects an IoT browser icon or has a specific code read on an initial screen, the IoT browser?300?may be executed.

FIG. 4?is a view illustrating a first method for executing the IoT browser?300?by the user selecting an icon according to an exemplary embodiment. After the IoT browser?300?is downloaded and installed by the user, an IoT browser icon?410?is displayed on an initial screen?400?of the smart device?40?as shown in?FIG. 4. When the IoT browser icon?410?is selected by the user, the smart device?40?executes the IoT browser?300?and displays it on the screen.

As described, the user may execute the IoT browser?300?by selecting the initial screen icon.

FIG. 5?is a view illustrating a second method for executing the IoT browser?300?using a QR code according to an exemplary embodiment. The QR code is merely an example and the smart device?40?may execute the IoT browser?300?using a specific code which is obtained through various code means (for example, a bar code, a QR code, an RFID, NFC, etc.)

Specifically, the smart device?40?reads a QR code corresponding to the IoT devices?115?first (S510). The QR code corresponding to the IoT device?115?may be attached to the IoT device?115?or may be located nearby. The QR code includes a code value corresponding to information of the IoT device?115?in such a form that the code value can be executed in the IoT browser?300. The code value may include ID information of the IoT device?115.

After that, the smart device?40?analyzes the QR code and extracts the code value. Specifically, the smart device?40?may extract the code value of the QR code in the form corresponding to the information of the IoT device?115?like "iotbrowser://lot?id=xabxsd23x" as shown in?FIG. 5.

The smart device?40?executes the IoT browser?300?using the extracted code value, and displays the IoT browser?300?on the screen (S530). At this time, the smart device?40?obtains location information of the IoT device?115?from the P-platform120?using the extracted code value, and displays a map area corresponding to the location information of the IoT device115?on the initial screen of the IoT browser?300.

The smart device?40?searches for the IoT device?115?using the ID of the IoT device?115?included in the extracted code value, and displays a result of the searching on the screen (S540).

By reading the QR code using the smart device?40?through the above-described process, the user may directly search for and select the IoT device?115?corresponding to the QR code on the IoT browser?300.
