Abstract

PURPOSE: A method for remotely controlling a home network is provided to share programs and user interfaces of another sub controllers and a network controller even when a local server of a main controller has a mobile IP, thereby enabling access to a browser of the main controller. CONSTITUTION: A home network completes a basic file setup(S10). A local server sets a port, and sets a socket(S20). The local server rewrites a basic connection file by using an IP address obtained through the set socket and the port(S30). If a product is controlled under an inner network environment(S40), the home network decides whether the product is directly controlled by a main controller or sub controllers(S50). If the product is controlled by the sub controllers, a user executes an abbreviated icon supplied through a GUI interface screen(S90). A browser checks the IP address and the port of the basic connection file, and connects with the local server(S100). Browsers of the sub controllers transmit a set product monitoring command or a product control command to the local server of the main controller(S110). The local server controls an operation of the product by using a network control program, or monitors the product(S120), and displays result data on screens of the sub controllers(S130).

Description

Method for remote control in home network

The present invention relates to a home network system, and more particularly to a method for performing remote control of a product through an external device when the local server has a floating IP.

In the early stages of home automation to automatically control home appliances in each home or remote area, each device was controlled separately using a telephone or infrared rays. Nowadays, a home network system that establishes a network between home appliances using communication means and has a controller for controlling the network is integrated and is approaching commercialization.

Referring to the schematic configuration of such a home network system, as shown in FIG. 1, a plurality of home electronic devices, such as a refrigerator, an air conditioner, a microwave oven, a washing machine, a personal computer (PC), and the like are connected through a communication bus to construct a home network. do.

In this case, Figure 1 is a case in which the microcomputer of each product has a serial communication function and directly connected to the communication bus, even if the microcomputer of each product does not have a serial communication function or uses a power line as a communication line, Is equipped with a communication module to form a home network.

And a controller for controlling the home network should be installed to control the network of the home network configured as described above.

However, since most personal computers are currently equipped with a personal computer, the personal computer is used without a separate controller. Therefore, it can be used as a network controller by installing an application program for controlling the network on the PC.

In this case, no problem occurs when the controller uses only one main controller, but a problem occurs when a product is to be controlled through another sub controller.

In other words, when the local server in the main controller has a floating IP scheme, when it is desired to manage and control a specific product by a device other than the controller (sub-controller), the control is possible only through the main controller.

Therefore, the sub controller must know the IP address of the local server to connect to the local server, thereby controlling a specific product.

However, if the local server of the main controller has a dynamic IP scheme, the sub server other than the main controller cannot know the IP address of the local server, and thus connection to the local server is impossible, which makes it impossible to control a specific product.

Accordingly, in order to control and manage a specific product, the user has to move to a specific place where the main controller is located.

Accordingly, an object of the present invention is to provide a method for remotely controlling a plurality of products connected to a home network through a plurality of other sub-controllers in addition to the main controller.

It consists of including.

Other objects, features and advantages of the present invention will become apparent from the following detailed description of embodiments taken in conjunction with the accompanying drawings.

A preferred embodiment of a remote control method of a home network according to the present invention will be described with reference to the accompanying drawings.

2 is a view showing the overall configuration showing the external network environment of the home network system according to the present invention.

Referring to FIG. 2, a web server 11 is connected to a web server 11 through a browser 10 of an external PC through an internet network, or a server according to a wireless application protocol, that is, a WAP, is connected to a portable communication terminal 20. Connect to the server and input the control or monitoring command of the home product 61. Then, the remote control server 31 that controls the communication from the outside to the home network environment transmits the input command to the main controller 50, which is the home network controller.

At this time, looking at the home network environment, the first and second sub-controller 41 of the general PC, a plurality of products 61 controlled by the first and second sub-controller 41, and the first, 2 is connected between the sub controller 41 and the products 61 by wire (LAN) or wireless (for example, Bluetooth: bluetooth) to the user control command and user control via the remote control server 31 of the external environment A main controller which monitors the commands and performs control of each product 61 in accordance with the monitored control commands and transmits the results to the first and second sub-controllers 41 and the remote control server 31; 50).

At this time, the main controller 50 has its own browser 51 providing a user interface in the form of a corresponding graphical user interface (GUI) through the stored GUI data 52, and the own browser 51 or the first and second PCs. The operating state of the product 61 is monitored or operated by using a preset network control program 54 in accordance with a user control command input from a browser in the 41 and a user control command input through the remote control server 31. It is composed of a local server 53 for controlling and transmitting the results to be displayed on the remote control server 31 and the browser of itself or the first and second sub-controller 41.

In the home network configured as described above, when the local server 53 uses a dynamic IP method other than the fixed IP method, the user can access the main controller 50 and the main controller 50 from the outside through the Internet. Only the control of the product directly through) can be made, and access to the main controller 50 by the first and second sub-controller 41 in the home becomes impossible.

Therefore, the first and second sub-controllers 41 have a disadvantage in that they cannot use the management of each product or the operation control for file transfer.

As a method for solving this problem, the following describes an interface method between the browser in the first and second sub-controllers 41 and the local server 53 in the main controller 50 in the home network system configured as described above.

3 is a flowchart illustrating a remote control method of a home network according to the present invention.

Looking in detail with reference to Figure 3 as follows.

First, a folder is created in the main controller 50, and the generated folder is set to be shared. A server program for controlling the corresponding product is installed, and the installed program is set to be a basic access file in the shared folder set above.

Finally, after generating shortcut icons in the first and second sub-controllers 41, the shortcut icons are set to point to the default connection file set above, thereby completing the basic file setting (S10).

Subsequently, for the dynamic IP method, the local server 53 sets a port for TCP / IP communication. Then, a socket for transmitting / receiving data from the local server 53 to the remote control server 31 and the first and second sub controllers 41 and vice versa and obtaining an IP address of the corresponding product is set. (S20).

Then, the set basic access file is rewritten using the IP address and port obtained through the set socket and stored in the shared folder. In the basic connection file rewritten in the main controller 50, the IP address and port obtained from the browser are shared and set to be accessible from the outside (S30).

On the other hand, when controlling the product in the internal network environment (S40), it is determined whether the product is controlled directly from the main controller 50 or the sub-controller 41 (S50).

As a result of the determination (S50), when the product is controlled by the sub controller 41, the user is provided by the local server 53 of the main controller 50 connected by wire or wirelessly in the first and second sub controllers 41. The shortcut icon provided through the GUI interface screen is executed (S90).

Then, the browser 41 accesses the shared folder stored in the local server 53 in the main controller 50 and checks the corresponding IP address and port in the recreated basic connection file to connect to the local server 53 ( S100).

The browser in the first and second sub-controllers 41 sets the product monitoring command or the product control command, and then sends the set product monitoring command or the product control command to the local server 53 in the connected main controller 50. Transmit (S110).

Subsequently, the local server 53 controls or monitors the operation of the product 61 by using the network control program 54 according to the transmitted product monitoring command or operation control command (S120), and then returns the result data. The first and second sub controllers 41 are displayed on the screen through the GUI interface screen (S130).

Therefore, the user controls the operation state of the product 61 by inputting a monitoring command or an operation control command through the first and second sub-controllers 41, such as a PC installed in each room, even without using the network controller 50 directly. In addition to monitoring, monitoring can also be performed.

In addition, when the main controller 50 is directly used (S50), except that data is not transmitted to the outside, a product monitoring command or a product control command is received (S60), and a network control program ( After performing product control and monitoring using 54) (S70), providing a GUI interface to the user is the same (S80).

In addition, when controlling the product in an external network environment (S40), first, the user accesses the web server 11 through the Internet using a third sub-controller 10 connected to the Internet, or a fourth communication terminal such as a mobile phone. The sub controller 20 is connected to the swap server 21 (S140).

Then, a product monitoring command or a product control command is input using a network control program provided by the web server 11 or the swap server 21 (S150).

Subsequently, the web server 11 or the swap server 21 accesses the local server in the same manner as described above (S100), and then transmits the monitoring command or control command to the main controller 50 through the remote control server 31. Transmit (S110).

The main controller 50 controls the operation of the product 61 according to the control command, and monitors the operating state of the product 61 according to the monitoring command (S120).

As a result, the data is transmitted to the web server 11 or the swap server 21 through the remote control server 31 again. Subsequently, the web server 11 or the swap server 21 displays the product control result or the monitoring result data on the browser 10 screen of the third sub controller or the display window of the communication terminal 20 of the third sub controller via the Internet. (S130).

Therefore, the user can control each product connected to the network through the first to fourth sub-controllers 41, 10 and 20, not the main controller 50, and also control the operation state of the product. You can check it.

As described above, the remote control method of the home network according to the present invention can share a program and a user interface of a separate sub-controller and a network controller even if the local server in the main controller has a dynamic IP. It can be connected and provides the convenience of the network controller to the user, and also improves the efficiency of the system.

Those skilled in the art will appreciate that various changes and modifications can be made without departing from the spirit of the present invention.

Therefore, the technical scope of the present invention should not be limited to the contents described in the embodiments, but should be defined by the claims.
