Description

Home Automation Method based on Jini}

The present invention relates to a genie-based home automation method, and more particularly, to a home automation method for remotely controlling devices in a home through a mobile communication terminal by installing a centralized service look up server. will be.

Jini is a Java-based network-distribution technology announced by Sun that enables the identification of peripherals on a network, regardless of protocol, and is used for home automation.

Since Genie generally uses existing Java technology, devices providing Genie services must be equipped with a Java virtual machine to operate according to Java programs. Communication between devices uses Remote Method Invocation (RMI).

The existing Genie service registers a service that can be provided by each device having the Java virtual machine, and then each device requests a service provided by another device, and the device that receives the service provides the service. Works. Due to the above method, Genie has an advantage of allowing a general home appliance to directly access a network such as the Internet without a separate operating system.

Genie services enable DVD drivers, digital cameras, disks, and printer computers to provide printing, data storage, and computation services to each other as soon as they are connected to the network. For example, when a disk is plugged into a network plug, TVs, refrigerators, language labs, and computers in the room can recognize it as a data storage service and share it with each other as needed to store data.

Each device providing a Genie service performs both a role of providing a service and a client of requesting a service. A device with a service function registers its service with a look up server (typically a PC plays this role), and a device that needs that service receives another service by applying for a service registered with the lookup server. You can use the functions of the system.

However, as described above, the home automation by Genie can only control the devices inside the home through a PC, and cannot remotely control the devices inside the home.

In the present invention, in order to solve the problems of the prior art as described above, a mobile communication requesting the control of the device to the home network server and the home network server to collectively register the service of the equipment providing the Genie service in a specific region The present invention proposes a home automation method that can control devices in a home using a terminal.

In order to achieve the above object, the genie-based home automation method according to the present invention connects a home network server and a device providing a Genie service through the Internet, thereby providing services of the devices providing the Genie service to the home. Registering with a network server (a); (B) providing user-controllable device information using the registration information in step (a) when the user requests a home automation service using the mobile communication terminal; (C) providing a list of services that the selected device can provide if the user selects a specific device; When the user selects a specific service, the home network server may include transmitting a control command of the user to the specific device selected by the user.

Another feature of the present invention is that the home network server further comprises providing the necessary software to the apparatus for providing the Genie service.

In addition, the present invention, when registering the devices for providing the Genie service to the home network server in the step (a), the same device to provide the same service by separating the service class and the user class is managed in one service class, the user When the service request of the user class and the service class, characterized in that applied together.

Hereinafter, a preferred embodiment of a genie-based home automation method according to the present invention will be described in detail with reference to the accompanying drawings.

1 illustrates a system configuration for implementing a genie based home automation method according to an exemplary embodiment of the present invention.

As shown in FIG. 1, a system configuration for implementing the present invention includes a mobile communication terminal 10, a short message center 11, a home network server 12, and devices 13 for providing Genie services. It is done by

In order to implement the present invention, a server for collectively managing the functions of each device providing a Genie service in a specific region is required. In the present invention, a server having such a function will be referred to as a home network server 12. Conventionally, the PC generally manages the equipment that provides the Genie service in a home, but since it is not easy to directly interface with the PC outside the home, the functions of each device providing the Genie service are collectively registered and controlled. You need a server. According to a preferred embodiment of the present invention, it is preferable that the apparatus 13 for providing the Genie service and the home automation server connect with an Internet protocol. If the device providing the Genie service is a wireless device, it cannot be directly connected to the server, so a local home network server (not shown) is used to transmit data to the local home network server using Bluetooth technology. The local home network server forwards the received data to the wired home network server. The service locator inside the home network server returns the appropriate service class among the registered services.

The mobile communication terminal 10 is used as an equipment for controlling a device providing a service outside the home. Control commands for the device 13 providing the Genie service are made through a short message. Therefore, a short message corresponding to a user's control command is transmitted to the short message center 12, and the short message center is a device for providing a genie service that can be controlled by the user by transmitting the received control command to the home network server. Give an order

2 is a flowchart illustrating a genie-based home automation method according to an exemplary embodiment of the present invention.

When the server providing the Genie service is connected to the home network server, as shown in FIG. 2, first, the service provided by each device 13 is registered in the home network server 12 (S20).

3 illustrates an example in which a TV providing a Genie service registers its service in a home network server.

As shown in FIG. 3, the home network server sends a register class to the TV to enable communication with the TV. The register class refers to the class that stores the function of each device. The TV registers the TV by sending services available through this register to the home network server. After registration, the TV's functions and environment settings are managed by the home network server 12.

Unlike a conventional lookup server, a home network server needs to register and manage a relatively large number of devices, so it is necessary to utilize storage space efficiently. According to a preferred embodiment of the present invention, for this purpose, it is preferable to separately manage a service class for managing the same type of devices together and a user class for managing user information. The same service menus are registered for devices A and B, which are devices of the same type, because allocating and managing storage space for each user wastes storage space. When a user requests a service, the service class and the user class may be applied together to use the storage space more efficiently.

When the registration of the devices providing the Genie service to the home network server is made, the user requests the home automation service using the mobile communication terminal (S21).

4 illustrates an example in which a user requests a service using a mobile communication terminal.

As shown in FIG. 4, when a user connects a mobile communication terminal with a home network server through a short message center to request a home automation service, the home network server recognizes the user who requested the service and can control the user. The list of devices is provided as text information through the short message center (S22).

When controllable device information is provided to the mobile communication terminal, the user selects a device to be controlled from the provided device list (S23). Selecting a particular device provides the user terminal with a list of functions that the device can service and that is registered on the home network server. As shown in FIG. 4, if there is a rice cooker, a TV, and a refrigerator as a device that can be controlled by the user, when the user selects the rice cooker, a list of rice time reservation and alarm when the rice cooker can provide is provided. will be.

The user selects a specific service that a specific device can provide using the mobile communication terminal (S24).

The control command corresponding to the service selected by the user is transmitted to the home network server (S25), and the device providing the Genie service performs the service selected by the user through communication with the home network server (S26).

The user can directly control a specific device using the mobile communication terminal, as well as control other devices through the device under control. 5 illustrates an example of controlling a device providing another Genie service through a device providing a Genie service.

In FIG. 4, when the user selects a service called alarm upon completion, the home network server provides a menu on how to provide an alarm service. 3, a TV alarm, a radio alarm, and a fluorescent lamp alarm are provided in this manner. If the user selects a TV alarm, the cooker needs to control the TV. 4 illustrates this case.

When the user selects the alarm service using the mobile terminal when the TV is completed, the cooker recognizes that the user has selected the alarm service through the TV through communication with the home network server (51). The home network server sends a register class 52 to communicate with the home network server to perform the service to the rice cooker where the original task will start.

The cooker finds a service in the home network server when the rice is cooked through the register class (53). At this time, the service function of the selected TV is returned to the rice cooker (54). When the rice is ready, the cooker uses the downloaded TV's service function class to call the TV to alert the TV, and the TV sends an alarm signal by turning on the power or displaying an indication that the rice is complete. .

As described above, according to the Genie-based home automation method according to the present invention, a mobile communication terminal can be used to control devices that provide Genie services in the home from outside the home, and can be upgraded through centralized management. There is an advantage that can easily provide the software. In addition, since the device can be controlled through an interactive text message module, which is provided by the Genie service, the device can be easily controlled than other home automation systems. In addition, since the home network server performs service registration and management instead of the limited terminal, the terminal simply provides an interface with the user, thereby reducing the load on the terminal.
