The present invention is a wireless home network system using a network, even if the access point is changed by visiting a neighboring home with a portable controller, the user can access the home server through the home server of the visiting home The present invention relates to a wireless home network system that can control the home appliances of its own home, as well as monitor the status of the home appliance, thereby extending the range of the controllable area and increasing control convenience.

Recently developed wireless home network system is connected to one or more home appliances and a home server that can centrally control the network network built in the building to enable mutual operation control.

The network network underlying the wireless home network system can be used as a power line installed in a building without establishing a separate LAN line. Therefore, by receiving power through the power line and using it as a network network, it is possible to transmit data such as control signals to a plurality of home appliances connected to the power line, thereby reducing the cost of building a network system in the building, and It has the advantage of being easier.

However, in the network system using the above power line, each home or office residing in a common building in which a single power line is constructed cannot distinguish signal transmission and reception through the power line. There was a problem that can be transmitted to the device.

This problem is not only limited to wireless home network systems based on power lines, but also occurs in wireless home network systems that transmit and receive data by radio signals (RF signals).

That is, the wireless home network system through the wireless network network has the advantage that can control each home appliance without space constraints and the initial network construction cost is low, but the control issued from one home due to the strong propagation characteristics of the RF signal There is a problem that a signal propagates to other homes and causes signal interference between neighbors.

In addition, due to the characteristics that the wireless signal is easily interfered by an obstacle, a wall, etc., an unwanted control error may occur when a user issues a control signal while moving within a radius that can be communicated. This will be described with reference to FIG. 1.

In the case of a common building such as an apartment, a complex server 30 is constructed to relay radio signals transmitted and received in one or more buildings (expressed as a complex).

Each home may be one or more home appliances to be controlled, a home server 10 that relays or issues a signal through network communication, and a moving user may perform operation control or status monitoring on a predetermined home appliance. And a portable controller 20 such as a PDA which issues a control signal and displays a control state.

 If a user of home A (HOME_A) visits a neighboring home (HOME_B) with the portable controller 20, he accesses the home server (10 ') of home B (ACCESS POINT) of the visited home. Since communication is attempted, home appliances of A household cannot be controlled. That is, since the wireless communication with the home server 10 of the A household is impossible, the household appliances of the A household are in an uncontrollable state. That is, the home server 10 'of the B household only recognizes the PDA2 20' registered as a client as a portable controller, so the PDA1 20 cannot control the operation of the home appliance of the B household. Use only as an access point.

As described above, in the wireless home network system through the wireless network, the access point to be connected is changed as the portable controller 20 is moved, thereby making it impossible to wirelessly connect to the home server installed in the home. There was a problem that it could not be done.

The present invention has been made to solve the above problems of the prior art, the object of which is to send a message to the home server of the home by using a message specification with a unique user ID added to the header, and a unique ID inherent in the message By suggesting the algorithm to switch the user's handheld controller, even if the access point is changed by visiting a neighboring home, the home server of the visiting home can be connected to his home server, thereby controlling the operation of home appliances or An object of the present invention is to provide a wireless home network system for smoothly performing status monitoring.

The wireless home network system according to the present invention for solving the above problems is to notify the operation control or status change of one or more client home appliances connected to the network network built in the home, and to the control command message received through the network Portable control to send and receive messages through the home server controlling the operation of the home appliance according to the built-in user ID, the home server and the wireless network, and issue a control command message with a unique ID of the registered home server. A home server, which is connected to a home server of each home and has a database storing device information and user IDs of at least one connected home server, is connected to another home server and a home server to which the portable controller is registered. It just includes a server that switches messages sent and received between them.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, the configuration of the wireless home network system of the present invention will be briefly described.

The network constructed for home networking is not limited in its kind, such as a power line, a wired LAN, a telephone line, but the present invention illustrates a home network system that transmits and receives messages wirelessly, such as a wireless LAN or a Bluetooth standard.

First, the home servers 100 and 100 'control and manage a plurality of home appliances recognized as clients by transmitting and receiving a message through a wired network N or a wireless network. Therefore, the home server (100, 100 ') monitors the operation status, such as operation standby / operation progress / completion of the operation of a plurality of home appliances, and details such as detailed adjustment of the activated function among the unique functions of each home appliance Store information and manage it.

The portable controller 200 or 200 ′ is a device connected to the home server to enable the user to check status information or control operations of network home appliances in the home, and transmit and receive messages wirelessly with the home server. Representatives include PDAs, notebooks, and web pads.

Of course, the controller includes not only the portable controllers 200 and 200 ', but also a device such as a desktop computer connected to a wired network N and capable of inputting control commands and checking results.

The only server 300 is a kind of relay server that is shared with home servers 100 and 100 'arranged for each home, and functions as a portal server. Therefore, the complex server does not specify only an apartment complex, but is a concept of a server that manages a group when a home (office) in which a home server is installed forms one or more groups.

To this end, only the server 300 can be connected to each home server (100, 100 ') through the Internet network or can form a network group directly through a wired / wireless network, the number of home servers belonging to the jurisdiction group Manage user IDs. The user ID is a unique ID given to one home server, and an IP address is an example.

That is, general home appliances, portable controllers, and the like, which communicate with the home servers 100 and 100 ', issue a message having a new format including the user ID, which is illustrated in FIG. 2.

The format of the message is

{Header | command index | command code | command definition | argument ...},

As the command code, the definition, the argument value, and the like are combined and recognized as a control command, the operation of the device to be controlled is controlled.

In this case, the header includes not only length information of the entire message, but also a user ID uniquely assigned to the home server. Therefore, even if a given home appliance (eg, a portable controller) that issues the message is located in any home, the user ID is embedded in the message that is always issued.

 Therefore, any home server (100, 100 ') or only the server 300 of the home that has received the message can determine which home server is the portable control device (200,200') that issued the message. By reading the included user ID, it switches to the home server of the home and delivers the message.

3 and 4 illustrate a first embodiment and a second embodiment of a wireless home network system to which such a message is applied.

The first embodiment of FIG. 3 relates to a process of requesting a predetermined operation control by issuing a control command message by a portable controller moving to a neighboring home and confirming a result thereof, and the second embodiment of FIG. The present invention relates to a process of notifying a network change state detected by a server to a portable controller that has moved to a neighboring home.

First, referring to the first embodiment, as a user visits home B (home B) with the portable household appliance 200, the portable controller recognizes and accesses the home server 100 ′ of home B as an access point. . However, since the portable controller 200 is a client of the home server 200 of the home A (Home_B), the portable controller 200 does not have the control authority for the network home appliance of the home B. (①)

A user inputs a control command for a predetermined home appliance in the A household through the portable controller 200, and the portable controller issues a control command message including a user ID.

Receiving the control command message, the home server 100 'of the B family reads the user ID included in the message and transfers the corresponding message to the server 300 only when it is inconsistent with its user ID.

The complex server 300 stores device information about a plurality of home servers belonging to a jurisdiction group and information on a user ID uniquely assigned to each home server 100. Thus, the complex server refers to a database table and displays a corresponding message. To transmit to the home server 100 of A home. (③)

At this time, since the server 300 is aware that the portable controller 200 is connected to the B family, a notification message about an event issued by the home server 100 of the A family for a predetermined time from the point of time when the portable controller 200 is connected. B is set to transmit to the portable controller 200 connected to the home server of the home. The predetermined time is a value that can be changed and set by the producer and sets a normal outing time for visiting a neighboring family.

The home server 100 of the A household which receives the control command message from the complex server 300 issues a control signal so that the home appliance that is the control target connected to its network N performs the operation. Generate a result message regarding the control result. (④)

The generated result message is only returned to the access point (home server of home B, 100 'of the B household) to which the portable controller is currently connected via the server 300, and finally delivered to the portable controller. Therefore, the user can check the control result through the portable controller 200. (⑤)

Referring to the second embodiment of FIG. 4, as the user visits home B with a portable home appliance, the portable controller 200 recognizes and accesses the home server 100 ′ of home B as an access point. At this time, only the server 300 stores the connection state of the portable controller 200 based on the current home server of the B family.

When the status of the network home appliance in the A home, which is controlled by the home server 100 of A home, is changed, the home server detects an event for changing the status and generates a notification message.

The notification message is only transmitted to the server 300. If the notification message is within a predetermined time from the time of the first connection in the first embodiment, the complex server sends the notification message as B home home server (as set). 100 '). (②)

Similarly, the home server 100 'of the B household transmits the notification message to the portable controller 200. (③) As a result, a user who is visiting the neighboring family is generated at his home through the portable controller 200. You can check the network change status (e.g. alarm operation) (④).

The configuration of the home server 100 and the complex server 300 for this is as shown in FIG.

The home server 100 may include a communication unit 110 connected to a home appliance through a wired network network N, a wireless communication unit 120 receiving a control command message of a portable controller connected through a wireless network network; Microcomputer 130 for controlling the operation of the home appliance according to the control command input via the self-input control command or the network, and issuing an event notification message about the network state change, and one or more connected to the network It is configured to include a database 140 that stores device information, user setting information, and the like for home appliances. In this case, the control command message includes a user ID uniquely assigned to the home server having jurisdiction.

In addition, the home server 100 further includes an input unit 150 through which a control command is input by itself, and an output unit 160 which outputs a network change state according to the control signal of the microcomputer 110. Since the output unit 140 can be used as a touch panel device integrated with the input unit 130, a user interface environment can be more easily implemented.

In addition, the server 300 is a database 330 that stores the device information and the user ID uniquely assigned to each home server of the plurality of home servers (100, 100 ') forming the same network group, the plurality of home servers and control commands And a communication unit 310 for transmitting and receiving a message or a notification message, and a microcomputer 320 for switching a message transmitted and received through the communication unit to a corresponding device based on the details stored in the database.

As described above, the wireless home network system according to the present invention has been described with reference to the illustrated drawings. However, the present invention is not limited by the embodiments and drawings disclosed herein, and the technical idea of the present invention is within the scope of protection. Application is possible by those skilled in the art.

In the wireless home network system of the present invention configured as described above, an algorithm for switching a message to a home server of a corresponding home based on a message standard having a unique user ID embedded therein and a user ID embedded in the message is implemented in a server only. As a result, even if the access point is changed by visiting a neighboring home with a portable controller, the home server of the visited home can be used to control the status of home appliances and to monitor the status of home appliances. While extending the range, the home server controls the home appliance only in the case of a control command from a portable controller registered according to the user ID, thereby improving security when accessing from another home network, and greatly increasing convenience of control.
