The present invention relates to a home server and a control method thereof, and more particularly, to a home server and a control method thereof that verify state values of a home appliance and provide the same to a user interface device.

In general, a home network system refers to a network in which various home appliances are connected to each other to enjoy convenient, safe and economical living services at home and outside. With the development of digital signal processing technology, refrigerators and washing machines, which are called white household appliances, are increasingly digitalized. As home system operating technology and high speed multimedia communication technology are concentrated on digital appliances and new types of information appliances are emerging, Home network system has been developed.

Such a home network system can be classified into a data network, an entertainment network, and a living network depending on the type of service provided.

Here, the data network refers to a type of network constructed for exchanging data or providing Internet service between a PC and peripheral devices, and an entertainment network is a network between home appliances that handle audio or video information, Type. A living network is a network constructed for simple control of devices such as home appliances, home automation, and remote meter reading.

The home network system configured in the home includes a home server capable of controlling the operation of other home appliances or monitoring the status, a function of responding to the request of the home server according to the characteristics of home appliances or other factors, And a home appliance having a function of notifying the user of information about the home appliance.

1 is a flowchart for explaining a general home server control method.

Referring to FIG. 1, the home server periodically receives and stores state values from a home appliance (S10). Thus, if there is a status value request from a user interface (UI) device (S20), the stored status value is transmitted (S30).

At this time, a caching miss occurs and a state value of the home device stored in the home server becomes different from a state value of the actual home device.

That is, although the state value of the home device stored in the home server can be quickly provided to the user interface device, a problem different from the state value of the actual home device may occur, so a method for providing a more accurate state value Is emerging.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems and it is an object of the present invention to provide a home server capable of verifying the state value of the home appliance and providing the state value of the home appliance to the user interface device, And a control method.

In order to achieve the above object, a home server according to an embodiment of the present invention and a home server connected to a user interface device for displaying the state of the home device include a storage unit for storing state values transmitted from the home device, And a controller for transmitting the stored status value to the user interface device when the status value is requested from the user interface device, and verifying the stored status value.

Preferably, the controller requests a state value from the home appliance, and when the requested state value is received, a state value determiner that determines whether the stored state value matches the received state value, And a status value processor for retransmitting the received status value to the user interface device if the stored status value does not match the received status value.

The status value processor may update the status value stored in the storage unit corresponding to the received status value if the stored status value does not match the received status value.

Meanwhile, a home server according to an embodiment of the present invention and a user interface device for displaying the state of the home device are connected, and a control method of a home server in which state values of the home device are stored, Transmitting the stored state value to the user interface device if there is a request, and verifying the stored state value.

Preferably, the verifying step may include: requesting a state value from the home appliance, receiving the requested state value, determining whether the stored state value matches the received state value, And retransmitting the received status value to the user interface device if the stored status value does not match the received status value.

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

2 is a block diagram illustrating a home network system having a home server according to an embodiment of the present invention.

2, the home network system includes a home appliance 100, a home server 200, and a user interface device (hereinafter, referred to as a UI (User Interface) device 300).

The home device 100 transmits a status value indicating its own status information to the home server 200. [ At this time, the state value is periodically transmitted to the home server 200, and even when there is a state value request from the home server 200, the state value can be transmitted to the home server 200.

For example, the state value for the air conditioner may be an address, an operation mode, a desired temperature, a value for a room temperature, etc., and a state value for the washing machine may be an address, The time, the rinse number, the value for the remaining time, and so on, and the status value for the lamp may be a value for the address and power state, and so on.

The home appliance 100 may be implemented as a product such as a washing machine, a refrigerator, an air conditioner, a gas valve control device, an automatic door device, and a lamp.

The home server 200 includes a storage unit 210 and a control unit 220.

The home server 200 can receive the status value from the home device 100 and request the status value to the home device 100. [ The home server 200 may transmit the status value to the UI device 300 when there is a status value request from the UI device 300. [

The storage unit 210 stores various programs necessary for the home network system. In addition, the storage unit 210 may store the state value transmitted from the home appliance 100.

The storage unit 210 can update the state value of the home appliance 100 under the control of the controller 220 and store the updated state value.

Since the state value of the stored home device 100 includes unique address information for the home device 100 and a plurality of home devices 100 may be provided according to the assumption, Can be configured in the form of a table. Accordingly, the state value of the home appliance 100 can be conveniently managed by using the address information.

The control unit 220 controls the overall operation of the home network system. The control unit 220 transmits the status value stored in the storage unit 210 to the UI device 300 when the status value is requested from the UI device 300 and verifies the status value stored in the storage unit 210 can do. A detailed explanation will be given later in Fig.

The UI device 300 requests the state value from the home server 200 and receives the requested state value from the home server 200. [ Accordingly, the UI device 300 can display the state value of the transmitted home device 100. The UI device 300 may be implemented as a control device such as a PDA, a personal computer (PC), a wall pad, a home pad, and the like.

Also, the UI device 300 can receive the status value of the home appliance 100 from the home server 200 twice. That is, the status value can be received immediately after requesting the status value, and the next status value can be retransmitted sequentially. This means that the state value of the first transmission is an error value.

At this time, the UI device 300 displays the initially transmitted status value, and when the status value is retransmitted next, the initial status value is changed to the next status value and displayed.

Meanwhile, in the present embodiment, it is described that the home server 200 verifies the stored state value. However, as a modification of the present invention, the UI device may receive the first / second state value from the home server and verify Can also be implemented. Here, the first state value means a state value stored in the home server, and the second state value means a state value received and requested by the home device.

Specifically, the UI device compares the first state value received from the home server with the second state value.

Thus, when the first state value and the second state value coincide, the first state value is displayed. On the other hand, when the first state value and the second state value do not match, the second state value can be displayed.

The above-described operation of the UI device can be implemented through the following algorithm.

"Int [] cacheStatus = new int [deviceCount];

int [] realStatus = new int [deviceCount];

boolean [] displayed = new boolean [deviceCount];

i <deviceCount; i ++) // display the status value as many as the number of home appliances

{

  displayed = true; // Save visibility

  displayed (cacheStatus [i]); // display status value

}

if (cacheStatus [i]! = realStatus [i]) // If the first state value and the second state value are different

{

cacheStatus [i] = realStatus [i]; // Change the first state value to the second state value

if (displayed == true) // if the status value is displayed

{displayed (cacheStatus [i]);} // Display changed status values

 } "

Here, cacheStatus is a primary state value, realStatus is a secondary state value, and deviceCount is the number of home appliances residing on the home network system.

3 is a block diagram illustrating a configuration of a control unit according to an embodiment of the present invention.

3 and 2, the control unit 220 includes a state value determination unit 221 and a state value processing unit 223. [ The control unit 220 transmits the status value stored in the storage unit 210 to the UI device 300 when there is a status value request from the UI device 300. [

The control unit 220 may verify the state value stored in the storage unit 210. [

That is, the state value determination unit 221 requests the state value from the home appliance 100, and when the requested state value is received, it can determine whether the stored state value matches the received state value.

The state value processing unit 223 can process the state value according to the determination result of the state value determination unit 221. [ That is, the state value processor 223 can retransmit the received state value to the UI device 300 if the stored state value does not match the received state value.

The status value processing unit 223 may update the status value stored in the storage unit 210 to the received stored value.

The above-described operation of the control unit 200 can be implemented through the following algorithm.

"Int [] cacheStatus = new int [deviceCount];

int [] realStatus = new int [deviceCount];

List conflict = new List ();

sendData (cacheStatus); // Saves the saved state values to the UI device

RequestRealData (); // Request status values from your home device

i <deviceCount; i ++) // compare the state values by the number of home devices

{if (cacheStatus [i]! = realStatus [i]) // If the stored state value is different from the received state value

  {cacheStatus [i] = realStatus [i]; // Update saved state value to received state value

   addList (realStatus [i]); // Add state value to retransmit

   }

}

rsend (conflict); // Resend state value "

Here, cacheStatus is a state value stored in the home server 200, realStatus is a state value received from the home device 100, and deviceCount is the number of home devices existing on the home network system.

4 is a flowchart illustrating a method of controlling a home server according to an exemplary embodiment of the present invention.

Referring to FIG. 4, a home server receives a status value from a home appliance (S410). At this time, the state value of the home appliance can be periodically transmitted and stored in a predetermined list form.

If there is a state value request of the home appliance from the UI device (S420), the state value stored in the UI device is transmitted to the UI device (S430).

At this time, the stored state values are transmitted to the UI device and the stored state values are verified in parallel. Here, the verification method is as follows.

The state value is requested by the home appliance (S440), and the requested state value is received (S450). Thereafter, it is determined whether the stored state value and the received state value match.

If it is determined that the stored state value does not match the received state value, the received state value is retransmitted to the UI device (S460).

On the other hand, if the stored state value matches the received state value, no operation is performed.

Thereby, it is possible to provide a state value of the home appliance more quickly and accurately.

As described above, according to the present invention, the state value of the home appliance can be verified and provided to the user interface device, thereby providing a state value of the home appliance more quickly and accurately.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be understood that various modifications may be made by those skilled in the art without departing from the spirit and scope of the present invention.
