BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a home network control device and a method thereof, and more particularly, to a home or office in which a single Public Switched Telephone Network (PSTN) number (line) is registered. The present invention relates to a home network control apparatus using a short message service and a method thereof, which are suitable for remotely controlling simultaneously or individually (air conditioner, washing machine, etc.) through a single line.

In general, home networking refers to realizing information sharing and home automation through a network in a home. The home network that is in the spotlight now is not simply installing a LAN in the home, but ultimately, the Institute of Electrical and Electronics Engineers (IEEE) 1394, home RF (Radio Frequency), Bluetooth, etc. The next-generation interface means using organically connected home appliances such as audio, video, and refrigerators and computers in the house. As digital TVs become popular and DVDs (Digital Video Disks), digital camcorders, and digital video recorders become popular, people's demand for them will increase, and market formation and popularization will naturally occur.

Conventional technologies for such home networking include an air conditioner control system and a method of operating the same using a telephone network of Patent Application No. 10-2002-0075976.

1 is a block diagram of a system for controlling a single device of a home network using a conventional telephone network, and shows an example of an air conditioning control system using a telephone network.

Here, reference numeral 10 is an air conditioner having an outdoor unit and an indoor unit, 20 is a telephone, and they are connected to a public telephone switching network.

Thus, in general, an air conditioner is composed of an outdoor unit and an indoor unit, and the refrigerant circulating in the outdoor unit and the indoor unit forms a heat cycle of compression, condensation, expansion, and evaporation, and performs indoor air cooling or cooling.

Recently developed home network systems connect home appliances to networks built in homes or buildings, and use home appliances with home appliances that have high-speed processing and storage of data to perform server functions, or dedicated homes. Server appliances can be connected to a network to centrally control multiple home appliances.                         

In addition, as the home server has a gateway function to connect to the external Internet network, the remote controller can connect to the home server in the building and perform status monitoring and control command input of various home appliances controlled by the home server.

However, such a home network system requires a local area network (LAN) line to be built in a home or a building for smooth signal processing between home appliances connected to the network network, and a high speed internet network is used to remotely control the home network system. Since the preconditions that need to be formed at the national level are required, there is a limitation that it cannot be directly applied to regions or countries where the distribution of the Internet network is insignificant and large buildings or apartments.

Therefore, a control system of an air conditioner using an existing public switched telephone network has been developed to input a control command remotely to a plurality of air conditioner systems installed inside a home or building and perform condition monitoring of the air conditioner. 1 is a block diagram of an air conditioner control system using a telephone exchange network.

It is internally connected through a telephone network as a plurality of air conditioners are connected to a telephone terminal in a home or building, and as the telephone network is connected to the other party through an exchange, it is possible to transmit and receive signals through the telephone network with the outside. Therefore, the remote controller can operate the telephone 20 to make a call in a building or home where an air conditioner is installed, and input a control command by operating a button unit of the telephone 20, and the control command signal is transmitted to the air conditioner through the public switched telephone network. 10) to perform a control operation.

Fig. 2 is a block diagram of a multi-device control system of a home network using a conventional telephone network, and shows a configuration example of an air conditioner control system using a telephone network.

As shown here, a plurality of air conditioners 10 capable of transmitting and receiving signals through a telephone network; Remote electronic device such as a computer, which is newly registered by inputting setting information of the plurality of air conditioners 10 and a control program which can input a control command to some or all of the registered plurality of air conditioners 10, is driven. It is composed of

3 is a flowchart illustrating a method of operating a multi-device control system of a home network using a conventional telephone network.

As shown therein, a first step (ST1 to ST5) of executing the control program to register setting information regarding the plurality of air conditioners 10; Selecting a air conditioner to control and inputting a control command (ST6); A third step ST7 to ST10 of generating a control command data packet based on the setting information registered in the first step and automatically transmitting the control command data packet to the telephone network to which the air conditioner selected in the second step is connected.

The operation of the prior art will be described in detail with reference to the accompanying drawings.

First, in the prior art, the setting information of the air conditioner is registered so that control of the plurality of air conditioners 10 is automatically performed. For this purpose, a registration window using graphic images is provided on the screen so that the user can easily check the registration status, and the remote controller can display the installation location of the air conditioner, the phone number connected to the air conditioner, and remarks using the display window. When entering the control command, it is possible to check the setting information of the air conditioner.                         

The plurality of air conditioners 10 installed indoors for air conditioning are connected through an internal telephone network as they are physically connected to a telephone terminal of an installation place, and the internal telephone network is connected to a public telephone switching network via an exchange. Therefore, the remote controller may dial a telephone number provided to the internal telephone network and input a control command to the plurality of air conditioners 10.

When a plurality of air conditioners 10 are engaged with the same phone number, a unique ID is given to distinguish each air conditioner.

A public switched telephone network is a telephone network for a typical subscribing telephone service that provides voice and data exchange services to a large number of subscribers through an exchange office. The local switch switches several times depending on the telephone number dialed by the caller. As the telephone number is accessed, the telephone number is connected to the receiver.

The remote electronic device 30 is a device in which a control program is driven to output the status of a plurality of air conditioners and input control commands. The remote electronic device is a device having a built-in wired or wireless modem so as to be connected to a public switched telephone network. The controller includes an input / output unit to externally output an input of a control command through a control program and a result of performing the control command.

The remote controller may operate a control program driven by the remote electronic device 30 to input a control command to the air conditioner to be controlled, check the control state transmitted from the air conditioner, and the control program may be a GUI (Graphic User Interface). It is designed to provide the convenience of control operation to the user.                         

Therefore, the remote controller selects an ID given to the air conditioner to be controlled by operating a control program and inputs a control command. Thus, the ID of the specific air conditioner can be designated and controlled to be selected, and the plurality of air conditioners 10 are all selected. Alternatively, all can be released.

In order to control a plurality of air conditioners connected to a telephone number and to be connected through a telephone network, new settings are registered in a database by inputting setting information of a plurality of air conditioners. As part or all of 10) is inputted, control data can be quickly communicated with the air conditioner.

Therefore, when the control program is executed (ST1), an access is attempted by accessing a database storing the setting information of the air conditioner.

When the setting information is loaded, the control target is designated by selecting the number or ID of the air conditioner to be controlled by operating the control program (ST2).

If there is no setting information of the air conditioner or the database is inaccessible (ST3), an error occurs because the control program cannot designate an individual air conditioner and terminates the program, or requests a new registration (ST4).

The controller inputs the installation location, telephone number, ID, remarks, etc. of the air conditioner, and sets a communication port connected to the air conditioner to newly register the air conditioner (ST5).

When the air conditioner is selected, input control commands such as operation mode, wind direction, and air volume (ST6) and click the operation button. When the ID of the air conditioner, the telephone number connected to the air conditioner, and the communication port are already stored in the setting information, one transmission data packet including the control contents is generated (ST7).

After detecting whether the port is already set (ST8), if the port is closed, data communication is impossible, and if the port is open, control is terminated. After transmitting (ST9) and receiving the data packet, the air conditioner performs a control operation according to the control command included in the data packet (ST10).

The air conditioner generates the control state data after performing the control operation and sends the control state data to the remote electronic device to check the control state of the air conditioner through the control program of the remote electronic device.

The prior art will be described again by dividing the control into a single device and the control of a plurality of devices as follows.

First, in the case of a device control method using a conventional wired public telephone network, one device is usually controlled at a time, and there is no protocol for simultaneously controlling a plurality of these devices.

In other words, only one device was controlled at a time by the defined method, and the same product group or other company's products could not be controlled.

In addition, when controlling a plurality of devices were controlled using a device (Computer, etc.) that acts as a separate server.

1) Operation example of single device                         

It contains a call reception module inside the device, a controller module unique to the device, and an interface module for connection between the two modules.

In the basic operation, the device's own control module operates the device through user's operation (direct operation or remote control operation), and in the case of remote operation, the control module interfaced with the output of the module receiving the signal of the remote terminal performs the operation. do.

The operation signal at this time uses DTMF (Dual Tone Multi Frequency).

Thus, in the conventional single device operation, the voice band of the public switched telephone network is opened after the control device responds to the user's call, and then the user dials a number corresponding to a predetermined code.

For example, in the case of an air conditioner, if a user presses a predetermined number after answering a device, the air conditioner is operated or the air conditioner is stopped to control the operation.

2) Example of operation of multiple devices

This basically requires a separate device (Computer, etc.) for integrated control in a technology similar to the operation of a single device, each device is connected to the corresponding computer.

So remote signal reception is received by the computer and remote control of multiple devices.

In the case of controlling a plurality of devices, a control command is input to a separate server or computer based on a database that contains information of each device, or automatically controlled using data that is directly input or configured through a keyboard.

A plurality of devices are connected to one server, and the device and the server computer are controlled through serial communication.

However, this conventional technology has the following problems.

That is, since the control proceeds to some number configuration existing on the phone, it is difficult to set various conditions, the usability is poor, and there is a limit that a simple ON / OFF function is mainly used.

In addition, the operation of the plurality of devices was performed by separate control software using devices such as separate servers and computers. However, this is simply difficult to apply to all products, in the case of home (Home) has a problem that there is a limitation to install and use a separate server.

Accordingly, the present invention has been proposed to solve the above-mentioned conventional problems, and an object of the present invention is to provide a plurality of or multiple types of FSK processing apparatuses in a home or office where one wired public telephone network number (line) is registered.

Referring to the operation of the present invention in more detail as follows.

First, the short message service center 100 transmits the data transmitted from a remote location to the corresponding control target device 300 through the public switched telephone network (PSTN) and the number and unique ID (2 bytes) of the short message service center 100. Settable), control device number (settable to 1 byte), and FSK data are transferred between the first ring signal and the second ring signal.

Then, the plurality of control target devices 300 receiving the FSK signal at the same time check the contents of the data, and the device connects the line path only in the case of the content of the corresponding device, and the channel associated signaling (CAS) is performed. It will receive a signal and send an ACK signal.

The control target device 300 receives the CAS signal, processes it, sends an acknowledgment signal, an ACK-C signal, and waits for reception of body data including control data.

The type of body message comes as a control signal.

Thus, a response signal is sent after the reception of the body data is completed.

Then the operation is terminated by the termination parameter.

At this time, the field of the control data can be configured as shown in FIG.

This may be configured to include a short message service center number, a control target device ID (2 bytes), and a control target device number (1 byte).

Thus, the control data message may be configured as, for example, 0xXA (xxxx 1010b), whereby the control data may be transmitted from the short message service center 100 to the corresponding control target device 300.

In addition, in the control data message, the control target device ID (2 bytes) and the control target device number (1 byte) are the fields after the received short message service center number field, which causes the general short message service (SMS) data. And control SMS data are divided.

In addition, the ID of the control target device, which is a unique ID, may be configured as 2 bytes. For example, the boiler may be assigned to 0x01, the air conditioner to 0x02, the TV to 0x03, and a total of 255 codes may be allocated to the standard equipment. . Of course, increasing the allocation byte of the control device ID can also increase the number of control devices that can be allocated.

In addition, the control target device number can be configured as 1 byte, for example, living room air conditioner 0x01, study room air conditioner 0x02, home air conditioner 0x03, etc., and can be assigned to a total of 15 identical devices. In addition, increasing the allocation byte of the control device number can also increase the number of the same number of devices that can be allocated.

Meanwhile, the parameters may include the following.

1) EUC (Equipment Under Control) on / off parameter

2) EUC operation time start / end parameter

3) EUC temperature setting parameter

And the like are included in the control data message and passed to the controlled device (EUC) 300.

When transmitting the control data transmission message from the control unit 230 in the FSK processing unit 200 to the control target device 300, a field as shown in FIG. 7 may be formed and sent.

In addition, when the control target device 300 transmits a control data reception message to the control unit 230 in the FSK processing unit 200, a field as shown in FIG. 8 may be formed and sent.

Therefore, the FSK processing unit 200 transmits a control data transmission message when receiving the operation result of the control target device 300, and in the control data transmission message after the operation is started in the control target device 300 according to the transmitted contents. The execution result can be transmitted by using the included reply number parameter to receive a reply.

The result transmission from the control target device 300 uses a terminal response parameter (for example, can be used as 0x07) included in the control data transmission message (see FIG. 8) in the standard SMS protocol.

In addition, the ID of the control target device 300 and the control target device number are transmitted to the FSK processing unit 200.

On the other hand, in the case of reservation control, regardless of the time at which the user sends the message to the short message service center 100, the short message service center 100 sets the operation time + start time + time required for the operation in the control data message parameter. Send the message at the time considered.

On the other hand, the terminal user interface is performed as follows.

That is, the terminal applies a standard user interface (UI) for inputting control data.

In addition, the standard user interface selects the control target device 300 so that the lower input parameters are automatically aligned.

For example, if you select a boiler, the submenu displays temperature setting parameters. And if you select the rice cooker to set the cooking time completion parameters. In addition, when the light is selected, the light on / off time setting parameter is displayed.

As described above, the present invention is to remotely or simultaneously control a plurality of devices or a plurality of devices equipped with an FSK processing device through a single line in a home or office where one wired public telephone network number is registered.
