Abstract

A home server and a control method thereof are provided to provide a state value of a home device more rapidly and definitely by verifying a state value of a home device and providing the state value for a user interface device. A control method of a home server comprises the following several steps. The home server receives a state value from a home device(S410). If a user interface device requests the state value of the home device(S420), the home server transmits a stored state value to the user interface device(S430). At this time the home server verifies a procedure for transmitting a stored state value to the user interface device and verifies the stored state value in parallel. The verification method is as follows. The home server requests a state value to the home device(S440), and receives the requested state value(S450). The home server compares the received state value with the stored one, and if the received state value is different from the stored one, the home server retransmits the received state value to the user interface device(S460).

Preferably, the controller requests a state value from the home device, and when the requested state value is received, a state value determination unit determining whether the stored state value matches the received state value, and a determination result. And a state value processor for retransmitting the received state value to the user interface device when the stored state value and the received state value do not match.

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

On the other hand, a home device according to an embodiment of the present invention and a user interface device displaying the state of the home device is connected, the control method of the home server in which the state value of the home device is stored, the state value from the user interface device If requested, transmitting the stored state value to the user interface device, and verifying the stored state value.

Preferably, the verifying includes requesting a status value from the home device, receiving the requested status value, determining whether the stored status value and the received status value match, and determining a result. And if the stored state value does not match the received state value, retransmitting the received state value to the user interface device.

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

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

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

The home device 100 transmits a state value indicating its state information to the home server 200. At this time, the status value is periodically transmitted to the home server 200, and even if there is a status value request from the home server 200, it may transmit its own status value to the home server 200.

Here, the state value of the home appliance 100 may be, for example, a state value for the air conditioner may be an address, an operation mode, a desired temperature, a value for an indoor temperature, and the like. The value for the time, the number of rinses, the remaining time, and the like, and the state value for the lamp may be the value for the address and the power supply state.

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

The home server 200 includes a storage 210 and a controller 220.

The home server 200 may receive a status value from the home device 100 and request a status value from the home device 100. In addition, when there is a request for a status value from the UI device 300, the home server 200 may transmit the status value to the UI device 300.

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

The storage unit 210 may update and store the state value of the home device 100 under the control of the controller 220.

At this time, the stored state value of the home device 100 includes the unique address information for the home device 100, since the home device 100 can be provided in plurality in accordance with the home state value for each home device 100 Information about can be configured in the form of a table. Accordingly, the status value of the home device 100 can be conveniently managed using the address information.

The controller 220 controls the overall operation of the home network system. In addition, when there is a state value request from the UI device 300, the controller 220 verifies the state value stored in the storage 210 while transmitting the state value stored in the storage 210 to the UI device 300. can do. A detailed description will be described later with reference to FIG. 3.

The UI device 300 may request a status value from the home server 200 and may receive the requested status value from the home server 200. Accordingly, the UI device 300 may display a 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, or the like.

In addition, the UI device 300 may receive the status value of the home device 100 from the home server 200 twice. That is, the status value may be immediately received after the status value request, and the next status value may be sequentially retransmitted. This means that the first received status value is an error value.

At this time, the UI device 300 displays the state value transmitted first, and when the state value is retransmitted next, the UI device 300 changes the initial state value to the next state value and displays it.

Meanwhile, in the present embodiment, the home server 200 has been described as verifying the stored state value. However, as a modification of the present invention, the UI device receives the first / second state value from the home server and verifies it. It is also possible to implement. Here, the first state value refers to a state value stored in the home server, and the second state value refers to a state value received by requesting a home device.

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

Accordingly, when the primary state value and the secondary state value coincide, the primary state value is displayed. On the other hand, when the primary state value and the secondary state value do not match, the secondary state value can be displayed.

The above operation of the UI device may be implemented through the following algorithm.

Int [] cacheStatus = new int [deviceCount];

int [] realStatus = new int [deviceCount];

boolean [] displayed = new boolean [deviceCount];

for (int i = 0; i <deviceCount; i ++) // Display status value by number of home devices

{

  displayed = true; // save visibility

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

}

if (cacheStatus [i]! = realStatus [i]) // If the primary and secondary status values are different

{

cacheStatus [i] = realStatus [i]; // change primary state value to secondary state value

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

{displayed (cacheStatus [i]);} // Display Changed Status

 } 』

Here, cacheStatus is the primary status value, realStatus is the secondary status value, and deviceCount is the number of home devices existing on the home network system.

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

3 and 2, the controller 220 includes a state value determiner 221 and a state value processor 223. When the controller 220 receives a state value request from the UI device 300, the controller 220 transmits the state value stored in the storage 210 to the UI device 300.

In addition, the controller 220 may verify a state value stored in the storage 210.

That is, the state value determination unit 221 may request the state value from the home device 100, and when the requested state value is received, may determine whether the stored state value and the received state value match.

The state value processor 223 may process the state value according to the determination result of the state value determiner 221. That is, the state value processor 223 may retransmit the received state value to the UI device 300 when the stored state value and the received state value do not match.

In addition, the state value processing unit 223 may update the state value stored in the storage unit 210 to the received storage value.

The above-described operation of the controller 200 may be implemented through the following algorithm.

Int [] cacheStatus = new int [deviceCount];

int [] realStatus = new int [deviceCount];

List conflict = new List ();

sendData (cacheStatus); // Send to saved state UI device

RequestRealData (); // request status from home device

for (int 1 = 0; i <deviceCount; i ++) // Compare Status By Number Of Home Devices

{if (cacheStatus [i]! = realStatus [i]) // If the stored and received status values are different

  {cacheStatus [i] = realStatus [i]; // update the saved status with the received status

   addList (realStatus [i]); // add status to resend

   }

}

rsend (conflict); // resend status value

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

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

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

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

At this time, the stored state value is verified in parallel with the process of transmitting the stored state value to the UI device. Here, the verification method is as follows.

Request a status value to the home device (S440), and receives the requested status value (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 and the received state value do not match, the received state value is retransmitted to the UI device (S460).

Meanwhile, if the stored state value and the received state value match, no operation is performed.

As a result, it is possible to provide a state value of the home device more quickly and accurately.

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