[0192] FIG. 3 is a block diagram for explaining a specific configuration of the electronic device (100) of FIG. 2, according to one embodiment.

[0193] Referring to FIG. 3, the electronic device (100) may include at least one of a processor (111), a projection device (112), a memory (113), a communication interface (114), an operation interface (115), an input / output interface (116), a speaker (117), a microphone (118), a power supply (119), a driving unit (120), a sensor unit (121), or a moving device (122).

[0194] The configuration illustrated in Fig. 3 is merely an example of various embodiments, and some configurations may be omitted and new configurations may be added. The contents already described in Fig. 2 are omitted.

[0195] At least one processor (111) may be implemented as a digital signal processor (DSP), a microprocessor, or a time controller (TCON) that processes a digital signal. However, the present invention is not limited thereto, and may include one or more of a central processing unit (CPU), a micro controller unit (MCU), a micro processing unit (MPU), a controller, an application processor (AP), a graphics-processing unit (GPU), a communication processor (CP), or an advanced reduced instruction set computer (RISC) machines (ARM) processor, or may be defined by the relevant terminology. At least one processor (111) may be implemented as a system on chip (SoC) having a built-in processing algorithm, a large scale integration (LSI), or may be implemented in the form of a field programmable gate array (FPGA). At least one processor (111) may perform various functions by executing computer executable instructions stored in a memory (113).

[0196] The projection device (112) is a configuration that projects an image externally. According to various embodiments of the present disclosure, the projection device (112) can be implemented using various projection methods (e.g., a CRT (cathode-ray tube) method, an LCD (Liquid Crystal Display) method, a DLP (Digital Light Processing) method, a laser method, etc.). For example, the CRT method has the same principle as a CRT monitor. The CRT method magnifies the image with a lens in front of the cathode-ray tube (CRT) and displays the image on the screen. Depending on the number of cathode-ray tubes, it is divided into a single-tube type and a three-tube type, and in the case of a three-tube type, the red, green, and blue cathode-ray tubes can be implemented separately.

[0197] Another example is the LCD method, which displays images by transmitting light from a light source (e.g., a backlight) through a liquid crystal display. LCD methods are divided into single-panel and three-panel types. In the case of the three-panel type, the light from the light source is separated into red, green, and blue by a dichroic mirror (a mirror that reflects only a specific color of light and transmits the rest). After passing through the liquid crystal, the light can be focused again into a single point.

[0198] Another example is the DLP method, which displays images using a DMD (Digital Micromirror Device) chip. A DLP projection device may include a light source, a color wheel, a DMD chip, and a projection lens. Light output from the light source can be colored as it passes through the rotating color wheel. The light passing through the color wheel is input to the DMD chip. The DMD chip contains numerous micromirrors and reflects the light input to the DMD chip. The projection lens can play a role in magnifying the light reflected from the DMD chip into an image size.

[0199] Another example is a laser system that uses a Diode Pumped Solid State (DPSS) laser and a galvanometer. A multi-color laser uses three DPSS lasers, one for each RGB color, with their optical axes overlapped by a special mirror. The galvanometer includes a mirror and a high-power motor that moves the mirror at high speeds. For example, the galvanometer can rotate the mirror at up to 40 kHz / sec. The galvanometer is mounted according to the scan direction, but since projectors typically scan in a planar manner, the galvanometer can also be positioned separately along the x and y axes.

[0200] The projection device (112) may include various types of light sources. For example, the projection device (112) may include at least one light source among a lamp, an LED, and a laser.

[0201] The projection device (112) can output images with a 4:3 screen ratio, a 5:4 screen ratio, or a 16:9 wide screen ratio depending on the purpose of the electronic device (100) or the user's settings, and can output images with various resolutions such as WVGA (854*480), SVGA (800*600), XGA (1024*768), WXGA (1280*720), WXGA (1280*800), SXGA (1280*1024), UXGA (1600*1200), and Full HD (1920*1080) depending on the screen ratio.

[0202] The projection device (112) can perform various functions for adjusting the output image under the control of at least one processor (111). For example, the projection device (112) can perform functions such as zoom, keystone, quick corner (4 corner) keystone, and lens shift.

[0203] Specifically, the projection device (112) can enlarge or reduce the image depending on the distance from the screen (projection distance). That is, the zoom function can be performed depending on the distance from the screen. At this time, the zoom function may include a hardware method that adjusts the screen size by moving the lens and a software method that adjusts the screen size by cropping the image, etc. When the zoom function is performed, the focus of the image needs to be adjusted. For example, the method of adjusting the focus includes a manual focus method, an electric focus method, etc. The manual focus method refers to a method of focusing manually, and the electric focus method refers to a method of automatically focusing using a motor built into the projector when the zoom function is performed. When performing the zoom function, the projection device (112) may provide a digital zoom function and an optical zoom function that performs the zoom function by moving the lens through the driving unit (120).

[0204] The projection device (112) can perform a keystone correction function. If the height is not right for front projection, the screen may be distorted upwards or downwards. The keystone correction function refers to a function that corrects a distorted screen. For example, if distortion occurs in the left and right directions of the screen, it can be corrected using horizontal keystone, and if distortion occurs in the up and down directions, it can be corrected using vertical keystone. The quick corner (4 corner) keystone correction function is a function that corrects the screen when the center area of ​​the screen is normal but the corner areas are not balanced. The lens shift function is a function that moves the screen as it is when the screen is off the screen.

[0205] The projection device (112) can automatically analyze the surrounding environment and projection environment without user input to provide zoom / keystone / focus functions. Specifically, the projection device (112) can automatically provide zoom / keystone / focus functions based on the distance between the electronic device (100) and the screen detected by a sensor (depth camera, distance sensor, infrared sensor, light sensor, etc.), information about the space in which the electronic device (100) is currently located, information about the amount of ambient light, etc.

[0206] The projection device (112) can provide a lighting function using a light source. In particular, the projection device (112) can provide a lighting function by outputting a light source using an LED. According to one embodiment, the projection device (112) can include one LED, and according to another embodiment, the electronic device (100) can include a plurality of LEDs.

The mapping table (1100) may include account information and identification information of edge devices corresponding to the account information. The mapping table (1100) may be obtained through purchase history.

[0327] The identification information of the edge device (200) may indicate a unique number. One edge device (200) may have one unique number.

[0328] FIG. 12 is a drawing for explaining an operation of checking whether an edge device (200) is connected to a server (400) according to one embodiment.

[0329] The server (400) may store mapping information including account information and identification information of the edge device (200) (S1205). Mapping information related to the edge device (200) may be included in a mapping table. The mapping table may be a table generated based on multiple purchase histories. The mapping table may be updated based on additional purchase information.

[0330] With mapping information stored in the server (400), the electronic device (100) can determine whether a preset event for IoT environment analysis is identified (S1210). IoT environment analysis may include analyzing the network environment to indicate whether the edge device (200) is connected to the server (400).

[0331] The preset events for IoT environment analysis may include at least one of an event in which a user input for IoT environment analysis is received, an event in which a preset cycle arrives, an event in which an IoT environment analysis request is received from a server (400), an event in which the electronic device (100) is in a standby state (powered but not performing a specific function), an event in which a new edge device is identified in the IoT network (10), and an event in which an edge device that is disconnected from the IoT network (10) is identified.

[0332] When a preset event for IoT environment analysis is identified (S1210-Y), the electronic device (100) may perform a scan operation for IoT environment analysis (S1215). According to one embodiment, the electronic device (100) may move to perform the scan operation.

[0333] The electronic device (100) can request a connection status from the edge device (200) (S1220). The edge device (200) can receive a connection status request from the electronic device (100). The edge device (200) can check whether it is connected to the server (400) (S1221). The edge device (200) can obtain status information indicating whether it is connected to the server (400). The edge device (200) can check whether it is in a state where it can connect to the server (400). The edge device (200) can obtain status information as a result of the check. The status information can include at least one of a state where connection to the server (400) is possible or a state where connection to the server (400) is impossible.

[0334] The edge device (200) can transmit at least one of the identification information or status information of the edge device (200) to the electronic device (100) (S1222).

[0335] FIG. 13 is a diagram for explaining a permission table required for an edge device (200) to connect to a server (400), according to one embodiment.

[0336] Referring to FIG. 13, the server (400) may store an authorization table (1300). The authorization table (1300) may be information required for the edge device (200) to connect to the server (400). The authorization table (1300) may contain authorization information assigned to each edge device. The authorization information assigned to each edge device may vary depending on the type of edge device. For example, authorization information (ABC) for air purifiers (#A001, #A002, #A003) may be different from authorization information (DEF) for TVs (#T001, #T002, #T003). The authorization information may be described as confirmation information or an authorization code. Even if the identification information of the edge devices (200) is all different, some authorization information may be assigned in an overlapping manner.

[0337] The reason authorization information is required is to prevent edge devices from being indiscriminately registered with the server (400). Edge devices should be registered with the server (400) only by designated users or designated electronic devices (100). This is because edge devices should be controlled only by users.

[0338] In one embodiment, different edge device identification information may result in different authorization information. If the same authorization information is used for the same model, unauthorized users may gain access to multiple devices of the same model. To address this issue, different authorization information can be matched to each edge device's identification information.

[0339] FIG. 14 is a diagram for explaining an operation of obtaining connection information required for an edge device (200) to be connected to a server (400) according to one embodiment.

[0340] Step S1422 of FIG. 14 may correspond to step S1222 of FIG. 12.

[0341] When at least one of identification information or status information is identified from the edge device (200), the electronic device (100) can identify whether a preset event in which the edge device (200) is not connected to the server (400) has been identified based on the status information (S1430).

[0342] According to one embodiment, step S1430 may partially overlap with step S1210 of FIG. 12. For example, it is assumed that the preset event in step S1210 is an event that identifies a disconnected edge device (200). If an edge device (200) that is disconnected from a server (400) is identified in step S1210, the electronic device (100) can once again check whether the edge device (200) is connected to the server (400) through step S1430. Step S1430 may be described as an operation for identifying an event in which the edge device (200) is not connected to the server (400). The preset event mentioned in step S1210 may be described as a first event group, and the preset event mentioned in step S1430 may be described as a second event group.

[0343] According to one embodiment, a situation in which the edge device (200) is not connected to the server (400) can be identified by performing only step S1430 without performing step S1210 of FIG. 12. The electronic device (100) can identify that the edge device (200) is not connected to the server (400) based on the status information. For example, the electronic device (100) can repeatedly perform operations S1422 and S1430 until it identifies the edge device (200) that is not connected to the server (400).

[0344] If an event in which the edge device (200) is not connected to the server (400) is not identified (S1430-N), the electronic device (100) may repeatedly perform steps S1422 and S1430. For example, the electronic device (100) may repeatedly perform operations S1422 and S1430 until an edge device (200) that is not connected to the server (400) is identified.

[0345] When a preset event is identified that the edge device (200) is not connected to the server (400) (S1430-Y), the electronic device (100) can transmit at least one of a request for authorization information, account information, or identification information of the electronic device (100) to the AP device (300) (S1431).

[0346] The AP device (300) can receive at least one of a request for permission information, account information, or identification information of the electronic device (100) from the electronic device (100). The AP device (300) can transmit at least one of the request for permission information, account information, or identification information of the electronic device (100) to the server (400) (S1432).

[0347] The server (400) may receive at least one of a request for authorization information, account information, or identification information of the electronic device (100) from the AP device (300). The server (400) may determine whether the transmitted account information and identification information match the mapping information (S1440). The server (400) may determine whether the account information and identification information transmitted from the electronic device (100) are included in the mapping table.

[0348] If the account information and identification information do not match the mapping information (S1440-N), the server (400) may transmit a notification to the AP device (300) indicating that the identification information does not match (S1441).

[0349] The AP device (300) can receive a notification from the server (400) indicating that the identification information is inconsistent. The AP device (300) can transmit the notification indicating that the identification information is inconsistent to the electronic device (100) (S1442).

[0350] The electronic device (100) may receive a notification from the AP device (300) indicating that the identification information is inconsistent. The electronic device (100) may provide guide information indicating that the identification information is inconsistent (S1443).

[0351] If the account information and identification information match the mapping information (S1440-Y), the server (400) can obtain authorization information corresponding to the identification information (S1445). The authorization information may represent information for authenticating the authority required for the edge device (200) to connect to the server (400). The server (400) can transmit the authorization information to the AP device (300) (S1446). The AP device (300) can receive the authorization information from the server (400).

[0352] The AP device (300) can receive authorization information from the server (400). The AP device (300) can transmit the authorization information to the electronic device (100) (S1447).

[0353] The electronic device (100) can receive authorization information from the AP device (300). The electronic device (100) can generate (or obtain) connection information including at least one of account information, authorization information, AP information, and address information (S1448).

[0373] After the connection information is stored, the electronic device (100) can transmit the connection information to the edge device (200) (S1750). The connection information may include at least one of account information, permission information, AP information, or address information.

[0374] The edge device (200) can receive connection information from the electronic device (100). Based on the connection information, the edge device (200) can obtain at least one of account information, permission information, AP information, or address information (S1751). For example, if the permission information stored in advance matches the permission information obtained through the electronic device (100), the edge device (200) can decide to initiate a connection operation with the server (400).

[0375] The edge device (200) can determine whether pre-stored permission information is identified (S1752). The edge device (200) may pre-store permission information on its own. The edge device (200) can compare the pre-stored permission information with permission information acquired through the electronic device (100). The edge device (200) can determine whether the pre-stored permission information matches the permission information acquired through the electronic device (100). The edge device (200) can determine whether to initiate a connection operation with the server (400) through the comparison operation of the permission information. For example, if the pre-stored permission information matches the permission information acquired through the electronic device (100), the edge device (200) can determine to initiate a connection operation with the server (400).

[0376] If the previously stored authorization information is not identified (S1752-N), the edge device (200) can transmit a notification indicating no authorization to the electronic device (100) (S1754).

The authorization information stored within the server (400) may be the authorization information acquired in step S1445 of FIG. 14.

[0383] If the authorization information is not identified (S1760-N), the server (400) may transmit a notification indicating lack of authorization to the AP device (300) (S1761). The AP device (300) may receive the notification indicating lack of authorization from the server (400). The AP device (300) may transmit the notification indicating lack of authorization to the electronic device (100) (S1762). The electronic device (100) may receive the notification indicating lack of authorization from the AP device (300). The electronic device (100) may provide guide information for notifying lack of authorization (S1763). The operations of steps S1763 and S1754 may correspond. The guide information indicating lack of authorization may include a guide screen. The guide screen is described in FIG. 15.

[0441] In the IoT network (20) of FIG. 22, the electronic device (100) and the edge device (200) are described as being directly connected. In the IoT network (30) of FIG. 24, the electronic device (100) and the edge device (200) may not be directly connected. The electronic device (100) and the edge device (200) may be connected via an AP device (300). In addition, the terminal device (100-5) may be connected to the electronic device (100) and the edge device (200) via the AP device (300), and may also be directly connected to the electronic device (100).

[0442] For example, an electronic device (100) and an edge device (200) can be connected to an AP device (300) using a Wi-Fi communication module. The electronic device (100) and the edge device (200) can exchange information through the AP device (300).

[0443] The electronic device (100) and the edge device (200) may not perform direct communication with each other using a Bluetooth communication module.

[0444] Figure 25 is a drawing for explaining troubleshooting measures according to preset events.

[0445] The troubleshooting table (2500) of FIG. 25 may include troubleshooting information including troubleshooting actions. Problems may occur in the environment of an IoT network. The electronic device (100) may identify the cause of the problem and perform actions to resolve the problem. The electronic device (100) may store the troubleshooting table (2500). The troubleshooting table (2500) may include multiple cause(s) of the problem and actions (or measures) corresponding to the cause(s).

[0446] The operation of the edge device (200) performing a connection with the server (400) in a factory initialized state can be described as an on-boarding operation.

[0447] An operation of performing reconnection when the edge device (200) has already performed a connection with the server (400) and the connection with the server (400) is disconnected due to a specific cause can be described as a recovery operation.

[0448] The electronic device (100) can identify a preset event (such as an abnormal connection) related to an IoT network. The electronic device (100) can identify the cause of the preset event related to the IoT network.

[0449] The electronic device (100) can receive status information from the edge device (200). The related operations are described in FIG. 12. Based on the status information, the electronic device (100) can identify whether the edge device (200) is normally connected to the server (400).

[0450] The status information may include at least one of information indicating whether a connection to the server (400) is possible (e.g., normal connection or non-connection) or cause information (e.g., no connection history, AP device unresponsive, server unresponsive, unknown).

[0451] The electronic device (100) can determine the status of the edge device (200) as normal based on status information indicating a normal connection. If the edge device (200) is in a non-connected state (e.g., status information indicating non-connection), the electronic device (100) can determine whether to perform an onboarding operation or a recovery operation on the edge device (200) based on the status information.

[0452] For example, if the cause of the problem is a lack of connection history, the electronic device (100) may perform an onboarding operation. The electronic device (100) may transmit at least one of account information, permission information, AP information, and address information to the edge device (200) to connect the edge device (200) to the server (400).

[0453] For example, if the cause of the problem is an unresponsive edge device (200), the electronic device (100) can perform a first recovery operation. The electronic device (100) can transmit a control command to the edge device (200) to reboot the power of the edge device (200). The electronic device (100) can transmit a command to the edge device (200) to turn on the power of the edge device (200).

[0454] For example, if the cause of the problem is an unresponsive AP device, the electronic device (100) may perform a second recovery operation. The electronic device (100) may retransmit at least one of the permission information or the AP information to the edge device (200). The edge device (200) may retry connection with the AP device (300) based on at least one of the retransmitted permission information or the AP information.

[0455] For example, if the cause of the problem is a server failure, the electronic device (100) may perform a third recovery operation. The electronic device (100) may retransmit at least one of account information, permission information, and address information to the edge device (200). The edge device (200) may retry connecting to the server (400) based on at least one of the retransmitted account information, permission information, and address information.

[0456] For example, if the cause of the problem is unknown, the electronic device (100) may perform a fourth recovery operation.
