Description

Home network system and method using wireless communication network {Home network system and method using mobile network}

The present invention relates to a home network system and method using a wireless communication network. In particular, the wireless home gateway (G / W) and home automation (H / A) are integrated into the network so that when a visitor checks, prevents (or goes to bed) gas leakage, fire, etc. Or a home security management system that automatically informs the nearest fire / police office of the situation.

In the case of a video door phone used to recognize a visitor's visit at home, there is no way to respond by a visitor's call if there is no person in the house. For example, there is no way to inform the landlord when someone calls or an important person visits in an emergency, and they cannot cope efficiently in an emergency.

The home automation system that improves the disadvantages of the video door phone refers to the automation of home and housekeeping. The main systems include home security for home security and disaster prevention, home security, electricity and gas control, and meters. There are energy systems such as house control (automatic measurement and automatic cooking equipment), energy, lighting, heating and cooling, and hot water management.

For example, it is possible to automate the management of a house by switching a switch at a certain time to operate a video, a cassette, to lock a door, to control the temperature of a room or a bath, and to prevent gas leakage.

In such a home automation system with various functions, remote call and remote control using a telephone network is possible, but the function of the door phone (or video door phone) is only a peripheral device controlled by the home automation system. For example, in case of an emergency or a visitor, the home automation system can call a pre-entered telephone number through a landline telephone line (PSTN) or a LAN (LAN) to notify an emergency or to speak with a visitor.

However, in such a case, the caller can talk to the visitor, but cannot see his / her face by video, and because the connection is made through a PSTN or a LAN, the connection time is increased by passing through various exchange stations and base stations, and the connection rate is low.

In addition, the video memory video door phone, which can automatically record and preserve the visitor's appearance and visit time when not in the house, provides recording, but can not talk while viewing the visitor and the visitor in real time. There is a problem that can be confirmed only when you enter the house.

The following well-known technique is proposed as a conventional technique for solving this problem.

First, "application number; 10-2001-0003862, the title of the invention; the video door phone interlocking with the mobile phone and its control method" is provided with a mobile phone RF module assigned a unique number is directly connected to the mobile phone and the user Visitors were able to check through and make calls.

However, the known 10-2001-0003862 technology has a disadvantage in that its application range is limited to mobile phone devices by providing an RF module and a signal recognition unit assigned with a unique number.

In addition, "Application No .; 10-2000-0029902, Name of the invention; Intelligent door video phone and door remote opening system using the same" means that if there is no person in the house, the visitor's visit to the landlord is sent to the landlord at the remote site. The door can be opened by manipulating the door through the videophone.

However, the known 10-2000-0029902 technology includes a call signal receiving unit, a telephone number storage unit, and a transmitting unit, so that only a voice call is input to a telephone number previously input by a control program for transmitting a visit signal to a wired telephone or a mobile phone. The disadvantage is that it is possible.

In addition, "Application No .; 20-2001-0023181, Name of the Invention; Automatic Visitor Checking Service System in the Absence of Home" goes through the visitor authentication process when there is a visitor in the home and passes the visitor information to the remote host by SMS. I was contacted.

However, the well-known 20-2001-0023181 technology is constructed as an interphone device inside a home, an external interface with a keypad, and a home server in the home, and transmits the visitor's message information to a mobile phone, thereby real-time voice call and video with the visitor in the absence. The disadvantage is that the call is not possible.

As described above, the conventional techniques are not commercialized due to the weak reproducibility of the technology that can be actually applied and reproduced.

First, when the visitor presses the call button 101 of the door phone 100 attached to the front door, a call signal is generated and the call signal is transmitted to the door phone in the home through the wired home gateway 110 (S200).

The home gateway 110 of the door phone 100 displays a call signal for a predetermined time to determine whether there is a person in the home.

Here, the predetermined time represents, for example, the time until the preset call bell rings once or twice in five cycles (S202).

If there is a response to the call signal during the predetermined time period, it is determined that there is a person in the home and connected with the door phone of the home (S204), thereby enabling a call with the visitor (S206).

As a result of the determination, when there is no response to the call signal after a certain time, the home gateway 110 of the door phone 100 transmits the call signal to the external mobile communication terminal 160 through the CDMA module 106. It is to be connected to the mobile communication terminal 160 of the user.

At this time, the home gateway 110 of the door phone 100 transmits a call signal sequentially to the telephone number of the mobile communication terminal 160 set in advance by setting the priority (S208).

In addition, the camera 102 of the door phone 100 captures the image of the visitor and transmits the captured image to the external mobile communication terminal 160 in a predetermined calling order through the wireless home gateway 110. By doing so, the user receives the visitor's image along with the call signal.

In this state, the user recognizes the visitor's call through the external mobile communication terminal 160 and confirms the visitor's identity through the liquid crystal display of the mobile communication terminal 160.

At this time, when the external mobile communication terminal 160 is busy or absent, the mobile communication terminal 160 stores the message for the call signal and retransmits after a predetermined time elapses (S212).

If the user does not want to talk to the visitor to output the missed message through the speaker 104 of the door phone 100 by remote control of the mobile communication terminal 160 (S214).

If you want to call the visitor by identity verification (S216), the user remotely controls the external mobile communication terminal 160, the visitor's video through the liquid crystal display and the visitor's voice through the microphone / speaker, respectively By connecting to the output (S218) it is possible to make a voice call and a video call between the visitor and the user from a remote location (S220).

FIG. 5 is a flowchart illustrating an operation process when a situation such as crime prevention / disaster prevention / fire prevention occurs during absence (or sleeping) according to the present invention.

First, in the absence (or when going to bed), the user operates the HA device 140 including the security device 141, the lighting / temperature control device 142, the remote meter reading device 143, the information appliance 144, and the like. Set the state (S300).

At this time, the various sensors and the HA controller 145 in the security device 141 of the HA device 140 is operated to maintain a security state that can detect crime, disaster prevention, fire, etc. that can occur in the home in the absence. (S302)

In this state, when an abnormal detection signal such as unauthorized intrusion, fire, or gas leak is detected by the detection sensor in the home (S304), the HA controller 145 transmits the detected abnormal detection signal to the home gateway 110 (S306). )

At this time, the home gateway 110 compares and analyzes the reference data in the database (DB) and the detected abnormal detection data with each other (S308).

When the result of the comparison analysis of the data (S310), the abnormal detection data is determined to be above the reference value, the home gateway 110 transmits the abnormal detection data through the wireless communication network 150, the mobile communication terminal 160, PDA 165 and police station / Send to fire station 170 respectively.

At this time, the home gateway 110 of the door phone 100 determines the priority and sequentially transmits a call signal to the telephone number of the preset mobile communication terminal 160. Of course, the PDA 165 uses the same method.

In addition, the home gateway 110 transmits the abnormality detection data to the PC 190 or the SMS 195 through the Internet network 180 (S312).

Therefore, if there is a crime / disaster / fire prevention such as intruder monitoring, gas leakage, fire, etc. in the absence, it automatically notifies the relevant situation to an external mobile communication terminal (or PDA, PD, SMS, etc.) and the nearest fire / police station. As a result, property loss can be reduced.

As described above, according to the home network system according to the present invention, by integrating a wireless home gateway (G / W) and home automation (H / A) functions to build a home network, various HA devices can be easily controlled from a remote location. Of course, if there is a visitor in the house in the absence, it is possible to confirm the visitor through a quick identification procedure, and to make a voice call and a video call with the visitor if necessary.

In addition, in case of absence or going to bed, in case of crime prevention / disaster prevention / fire prevention such as invader monitoring, gas leakage, fire, etc., it is automatically controlled by external mobile communication terminal (or PDA, PD, SMS, etc.) By informing, the loss of property and personal injury can be minimized.
