The present invention relates to a system for controlling various devices at a remote location, and more particularly, to an apparatus and method for controlling various home devices at a remote location by using a short message of a mobile phone.

Nowadays, due to the rapid development of the industry, telephones and various home appliances such as TVs, VCRs, audio, microwaves, washing machines, refrigerators, etc. are widely used in all homes or offices for work.

In addition, such home appliances are developed and used in the remote control device (hereinafter referred to as a remote controller) mostly by those skilled in the art in order to meet the tendency to seek better convenience of users. Therefore, many home appliances are equipped with a control function so that the user can easily remotely control the remote control.

However, the remote control is capable of remote control of the device only at a nearby remote location (usually within 20m) due to its technical characteristics, and when an obstacle such as a wall is blocked between the remote control and a home device, or the user wants to control the device from outside the home. If there was a problem that can not be used. Therefore, users are not satisfied with this and seek for better convenience of use.

For example, something has been sought from the outside that can be used to control desired devices in the absence of a telephone or the like.

In recent years, in order to meet the needs of users, devices for remotely controlling home appliances using telephones have been developed one after another and used in various devices (Korean Patent Publication No. 1996-020299).

1 is a view showing the configuration of a remote control system for remotely controlling home appliances using a telephone according to the prior art.

As shown in FIG. 1, a control unit 2 provided separately in the telephone 1 is connected through an interface line 7, and the control unit 2 is connected to a plurality of household appliances, that is, a washing machine through each control line 8. (3), TV (4), light bulb (5) and various household appliances (6).

Therefore, when the user inputs a data value for remote control by controlling a device through a telephone from the outside, the control unit 2 controls the telephone 1 and the interface line 7 through the connection structure as described above. In response to a remote signal input from the outside through the control line 8 to control the power supply or other necessary functions of the corresponding equipment.

However, such a conventional remote control system can perform only the controllable operations by controlling the on / off of the power source or the simple switching operation in the control of each device, and perform various functions of the corresponding devices. There is a limit.

In addition, in order to transmit a control signal to a corresponding device through a telephone, a corresponding device must be selected from among a plurality of devices, and a predetermined data value must be input to the selected corresponding device through numbers, special characters, etc. for control. You will feel very complicated steps and hassles.

In addition, in order to control all kinds of home appliances, the user must know all the preset data values for each device in order to control precisely. It will be almost impossible to remember correctly every time, in conjunction with control.

In order to solve this problem, the user may separately enter a guidebook in which the control content and the data value are interconnected so that the data value may be input through the guidebook whenever the user controls the device. Rather, it is a hassle to find a guidebook for control.

In addition, continuous input of numbers or special characters is likely to input wrong data values when inputting, and this mistaken data value may cause malfunction of home appliances, which may cause a very dangerous or difficult situation. There will be.

In order to solve this problem, instead of inputting numeric values or special characters, a fixed menu is provided on the display window of the mobile terminal by using the WAP contents provided in advance by using WAP of the mobile phone. By searching and selecting this, it may be provided to control the washing machine in a remote place.

In addition, in order to inform the external user of the current operation state of the device to be controlled, the device detects the current operation state of the corresponding device and performs a predetermined signal processing, and then the state detection signal of the device to the external user through the display window of the mobile phone. Will be delivered.

At this time, in order to transmit the signal to the outside by the operation state of the device, a separate signal processing unit for the current state signal must be added to each device.

However, this method has no choice but to provide only a control command limited to the portable terminal to the menu, which also has its limitation in controlling the corresponding device.

That is, when all the control commands of the device are provided on the display window of the portable terminal, many key operations must be performed to retrieve the corresponding control commands, and the depth from the main menu to the execution operation menu for control will be provided very deeply. Therefore, not only the search takes a long time, but also causes the complexity of the search menu, which gives the user a difficulty in use.

Accordingly, the present invention has been made to solve the above problems, and provides a character recognition home automation system for controlling home appliances in a remote place using control command data converted through a short message of a mobile phone through an external server.

The measured data value is compared with the stored data value to determine whether it is a control command corresponding to the household device configured through the home automation system, It consists of a system controller 150, and a home device 160 that performs the operation corresponding to the data value sent from the system controller 150 to transfer the data value.

In this case, the home appliance 160 is a home automation system including a TV, a VCR, an audio, a microwave oven, a washing machine, a refrigerator, a dishwasher, and the like, and has a structure connected to communicate with the system controller 150.

In addition, each of the home appliances 160 has a serial number, and the system controller 150 searches for a serial number among data values input from the outside and transmits a control signal to the corresponding device, or transmits each series to the outside. Along with the number, the current status information of each household device is transmitted.

The system controller 150 is preferably a home personal computer (PC) having an external communication connection device such as a modem, a LAN card, or a wireless communication connection device.

In addition, the short processing server 120 finds a data value using a natural language processing method, and combines a dictionary meaning of each word in a sentence of a short message called from an SMS (Short Message System) center 110 or a sentence. Determining the meaning of the control means to compare with the previously stored data value to detect and combine the data value.

With reference to the accompanying drawings, the operation of the character recognition home automation system and the method for controlling home appliances using the same according to the present invention configured as described above will be described in detail as follows.

3 is a flowchart illustrating a method of controlling a home appliance using a text recognition home automation system according to the present invention.

Referring to FIG. 3, first, a user at a remote location requests an authentication for controlling a home device 160 after accessing a remote control server 140 using his portable terminal 100. (S10).

At this time, the authentication request, the user makes a call to the mobile communication center 130, accesses the set home automation and enters their ID and password. Then, the mobile communication center 130 transmits the input ID and password to the remote control server 140.

In this way, the remote control server 140 receiving the ID and password compares the member information previously stored in the member authentication DB with the input ID and password to determine whether to permit authentication (S20).

In the case of the non-member as a result of the determination, the guide according to the registration procedure is transmitted to the mobile communication center 130 together with the "authentication failure" message, and the mobile communication center 130 requests the user's portable terminal 100 for authentication. ) To be displayed on the display window (S30).

In addition, if the result of the determination of the authentication permission is a member, and transmits the "Authorization permission" message to the mobile communication center 130, the mobile communication center 130 transmits to the mobile terminal 100 of the user who requested the authentication Will be displayed. At this time, the remote control server 140 simultaneously transmits the current status of the plurality of devices 160 connected to the home automation system of the user who has been “authenticated” and transmits the same to the portable terminal 100 of the user. To be displayed.

To this end, the remote control server 140 is present in a plurality of devices 160 connected to the home automation system in the home through communication through a modem, a LAN card, etc. attached to the corresponding home system control unit 150. You will receive the status from time to time.

Accordingly, the user can remotely check the current state of the device 160 in the home that he wants to control. In this case, checking the current state of the home device is a user's option, and when confirmation is not necessary, only authentication permission may be requested.

When the authorization is completed, the user is connected to the SMS (Short Message System) center 110.

At this time, the connection with the SMS center 110 transmits an "authentication permission" message to the user's portable terminal 100 through the mobile communication center 130, and the mobile communication center 130 is connected to the corresponding mobile terminal ( 100 is directly connected to the SMS center 110.                     

Here, even if the connection is not made immediately due to the user's rejection, the mobile communication center 130 notifies the SMS center 110 that the portable terminal 100 has received the authentication permission. Therefore, the user can access the SMS center 100 through the portable terminal 100 for a predetermined time after the authentication permission.

Alternatively, by separately transmitting a code number for authorizing the authentication to the "authentication permission" message transmitted to the user's portable terminal 100, the user inputs the transmitted code number when connecting to the SMS center 110 later. It may be connected to the SMS center 110.

When the connection with the SMS center 110 is made in this manner, the user transmits a short message for controlling the corresponding device through the portable terminal 100 (S40).

Then, the SMS center 100 stores the short message input from the portable terminal 100, and then transmits the stored short message to the short text processing server 120. In this case, the SMS center 100 transmits the information of the corresponding user together with the short message transmitted to the short processing server 120, which informs the fact that the mobile terminal has received the authentication permission. Will be sent.

The information of the corresponding user includes a number of a portable terminal, an IP address of a system controller located at a remote location, and a serial number of the corresponding device.

The short message processing server 120 generates a data value according to one control command by detecting and combining any one or a plurality of previously stored data values using a natural language processing method (S50). ).                     

In this case, the short processing server 120 stores the components and control commands of the home automation system for each user in advance through a user DB, which is a member of the home automation system. The configuration of the user DB separately / additionally to update / replace the contents stored in the user DB, or the user DB through the communication between the home system control unit 150 and the short processing server 120 through the remote control server 140 The contents of the home automation system stored in the home are updated / replaced so that they can be automatically updated / replaced at any time.

In addition, the control command of each device stored in the user DB is continuously upgraded for a new product through a manufacturer, a company or a separate control command service company.

As an example, a short message is inputted as a short message called to a short processing server storing data values according to each device, such as "turning on the washing machine and starting washing to a standard course!" As follows.

A sentence of the called short message is classified for each word.

That is, after classifying as "washing machine", "power source", "on", "standard course", "washing", "start", each word is determined in a dictionary meaning of the sentence.

First, a serial number corresponding to a washing machine is detected as a data value stored in a corresponding user DB in the short processing server 120 through the word "washing machine". In this case, when there are a large number of washing machines in the home, the user transmits a short message such as the first, second, and third washing machines or the washing machine 1, the washing machine 2, etc. which are previously agreed between the short processing server 120 and the user to the SMS center 110. Done. If the short message is not input according to the device of the same model, the short message processing server 120 receives an error message via the remote control server 140 through the mobile communication center 130 and the user portable terminal 100. Will be sent to.

In this way, among the plurality of home appliances composed of home automation systems, data values according to the washing machine are detected in the user DB.

Subsequently, the words "power" and "on" are used to determine the meaning of the sentence in a dictionary meaning to detect data values for turning on the power of the selected washing machine. At this time, the "power source" has the same data value as "power" and the like having the same dictionary meaning, and the "on" has the same data value as "turn on" and the like having the same dictionary meaning.

Subsequently, the words "standard course", "laundry", "beginning", etc. are identified in a dictionary meaning, and each data value corresponding thereto is detected. In this case, each word is detected with the same data value between words having the same dictionary meaning.

Finally, the detected data values are combined into one to determine the meaning of the sentence and the data values are generated according to the final control command.

The generated data value is transmitted to the corresponding home system controller 150 through the remote control server 140 (S60), and the system controller 150 reads the input data value and stores the data value previously stored in the memory. And the transmitted data value are compared (S70).

When the data value stored in the memory has the same data value, the data value stored in the memory is calculated.

In this case, in comparing the input data value with the pre-stored data value, an error range generated due to a high frequency or a low frequency due to an error and noise of a transmission line is appropriately applied to define a data value positioned within the error range as the same data value. do.

In addition, it is preferable to transmit the data value stored in the memory of the system controller 150 in the home to the corresponding device 160 without using the transmitted data value to reduce the operation error of the corresponding device according to the error range ( S90).

As a result of the comparison, when it is determined that there is no data value in which the input data value and the data value previously stored in the memory match, the system controller 150 passes the mobile communication center 130 via the remote control server 140. Sends an error message to the user's portable terminal 100 through.

At the same time, the remote control server 140 immediately recognizes that the operation of the corresponding device 160 is not performed by the transmitted data value, and does not change the contents according to the current state of the corresponding device. According to the time set in step 160, the user may be able to solve an error that occurs when the user inquires the state of the device before receiving the current state information.

Subsequently, when a data value according to a control command is transmitted from the system controller 150 to the corresponding device 160, the corresponding device 160 executes an operation of the corresponding device corresponding to the input data value. The current state is transmitted back to the system controller 150 (S100).

Then, the system controller 150 transmits the input state information of the corresponding device 160 to the remote control server 140 to update the state information according to the corresponding device input to the remote control server 140.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the 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.

As described above, the character recognition home automation system and the method of controlling a home appliance using the same have the following effects.

First, the user can increase the convenience of the user because the user can control the operation of the device in the home using an external communication device from a remote location regardless of the place.

Second, by separately installing a short processing server in the outside, it is possible to more stably control the home appliances in the home through a short message from a remote location.

Third, anyone can easily control home appliances from a remote location while minimizing the economic burden on installing a home automation system.
