Description

Wireless home gateway system for wireless data communication

The present invention relates to a wireless home gateway system for wireless data communication. In particular, in case of crime prevention / disaster prevention / fire prevention, such as visitor confirmation, gas leak during sleep (or at bedtime), fire, etc., wireless data communication between door phone linked with wireless home gateway (G / W) and external mobile communication terminal is possible. It relates to a wireless home gateway.

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.
