2 is a flowchart illustrating a cloud-based smart home service method according to an exemplary embodiment.

2, the cloud-based smart home service method according to an embodiment proceeds to the following process. First, the home cloud receives a user request from a user terminal (201). The home cloud converts the protocol of the received user request to communicate with the Internet information appliance and transmits the protocol to the home gateway (202). The home gateway transmits the user request received from the home cloud to the internet information appliance (203). The Internet information appliance transmits the Internet information appliance related information to the home gateway according to the received user request (204). The home gateway transmits the received Internet information appliances related information to the home cloud (205). The home cloud stores the received Internet information appliances related information in a database and transmits the information to the user terminal (206).

The home cloud receives a user request sent by the user terminal. User requests include real-time monitoring requests, control requests, and information retrieval requests.

If the user request is a real-time monitoring request or control request, the virtual home gateway of the home cloud converts the protocol of the user request to enable communication between the Internet home appliances and the home cloud. The protocol of the home cloud uses TCP / IP. There are various types of wired / wireless protocols such as TCP / IP, Wi-Fi, PLC, ZigBee, etc. according to the purpose and performance of each Internet information appliance. The protocol can be installed in a virtual home gateway in the home cloud and used in the home cloud. The protocol-converted user request is sent to the data relay manager of the home gateway. The data relay manager transmits the user request received from the home cloud to the corresponding Internet information appliance. The Internet information appliance transmits the Internet information appliance related information back to the home gateway based on a user request received from the home gateway.

If the user's request is a real-time monitoring request, Internet Information Appliances can provide information about Internet Information Appliances, including various environmental information such as temperature and humidity, air condition, presence of people, and information that are collected and measured in the environment. Send to home gateway. If the user request requests control of the Internet information appliance, the Internet information appliance operates under the control of the user request and transmits the information related to the Internet information appliance to the home gateway including the performance result according to the operation. And the home gateway transmits the Internet information appliances related information received from the Internet information appliances to the home cloud.

The home cloud stores internet information appliances related information received from the home gateway. In addition, the server generates metadata having attribute information for quick retrieval and mapping of stored Internet information appliances-related information, and stores the metadata. And the received Internet information appliances related information is transmitted to the user terminal.

In addition, the information related to the Internet home appliances may be periodically stored in the home cloud according to the user's settings. If the user wants to periodically store the information related to Internet information appliances, the home cloud periodically requests the information related to Internet information appliances from the home gateway. The home gateway transmits the received request to the internet information appliance, and the internet information appliance transmits the internet information appliance related information to the home gateway according to the received request. The home gateway transmits the received Internet information appliances related information to the home cloud. The home cloud stores the received Internet information appliances related information. If the received user request is an information retrieval request, the home cloud searches for metadata stored in a database based on the received user request, selects information related to Internet information appliances requested by the user, and transmits the information to the user terminal.

3 is a flowchart illustrating a cloud-based smart home service method when a risk situation occurs according to an embodiment.

Referring to FIG. 3, internet information appliances installed in a home measure information related to a surrounding environment through various sensors provided. For example, Internet information appliances related to air conditioning and heating measure indoor and outdoor temperatures, and air purifiers measure the condition of internal air. Other information electronic appliances measure a variety of information, such as human access and gas leak detection. Home gateways consider this a dangerous situation if the information about the surrounding environment measured and collected by Internet home appliances is in an abnormal range compared to the threshold. If the risk occurs, communication between the home gateway and the home cloud cannot be guaranteed. Therefore, when a risk occurs, the home gateway itself transmits a danger signal as well as the communication with the existing home cloud. In addition, it transmits a command to cope with the danger situation to the Internet Information Appliance. Internet home appliances perform emergency actions according to commands received from the home gateway.

The aforementioned countermeasure in case of occurrence of a risk situation can be applied even when a communication failure between the home gateway and the home cloud occurs. When a network failure occurs between the home gateway and the home cloud, the home gateway transmits it to the user terminal and the Internet information appliances are controlled through the home gateway. This enables control and management of basic Internet information appliances even in the event of a sudden network failure.

When a new Internet information appliance is added to the home and connected to the home gateway, the device change detection unit of the home gateway automatically detects it and collects information related to the Internet information appliance having information on the corresponding internet information appliance. The home gateway transmits the received internet information appliances related information to the home cloud. The home cloud identifies the added Internet information appliances based on the received information on the Internet information appliances and transmits the facts to the user terminal. In addition, changes in Internet-related information appliances are stored in a database. In this process, a new ID is assigned to the Internet information appliance added at the request of the user.

Although the present invention has been described in detail with reference to the above preferred embodiments, the present invention is not limited to the above embodiments, and various modifications may be made by those skilled in the art within the scope of the technical idea of the present invention. Do.
