Description

Home network control system using zigbee communication

The present invention relates to a home network control system using Zigbee communication. More specifically, a home network that can remotely control fingerprint door locks, gas valve controllers, and window intrusion detectors using ZigBee or Ethernet communications after connecting to a home network server through the Internet using a mobile communication terminal. It relates to a control system.

Today, as digital technology advances, the distinction between existing technologies, industries, services, and networks, such as wired and wireless, broadcasting and telecommunications, online and offline, is blurring, and new types of converged products and services are emerging. As the era of digital convergence arrives, distance education, entertainment, health care, and information appliances control are possible by utilizing various IT (Information Technology) devices based on high-speed infrastructure. The home network system (House Network System) that makes it come into the spotlight.

In general, a home network system is a digital home system in which information in a home is connected to a network so that service is performed regardless of device, time, and place. In other words, the home network system connects various control devices in the home such as TV, refrigerator, air conditioner, PC, telephone, and lighting, and each room in the home such as a home room, kitchen, living room, and entrance through the Internet to connect mobile phones or PDAs (Personal Digital Assistants). It refers to a system that can control everything in the home using devices such as terminals, TVs and refrigerators. In order to enable such a home network system, home networking must be performed.

Home network systems use a variety of communication methods to implement remote control through a terminal or a device. There are two types of communication methods, a wired method and a wireless method.

Wired methods include Home Phone Networking Alliance (HomePNA) using telephone lines, Power Line Communication (PLC) using power lines, Ethernet and IEEE (Institute of Electrical and Electronics Engineers) 1394, Universal Serial Bus (USB), etc. Use In addition, the wireless method uses an infrared-infrared data association (IrDA) using infrared rays, a home radio frequency (RF) using a radio wave, a Bluetooth, a wireless local area network (UWB), and an ultra wide band (UWB). , IEEE 802.11, and the like.

Since the wired method uses an existing telephone line or a power line, an information appliance can be connected to a network at a low cost, and large-capacity multimedia communication is possible. In addition, since most of the information is connected to the power line can be used in any space, the information can be freely shared because the information is controlled by a single protocol (Protocol).

However, when configuring a home network system using a wired method, cable wiring such as a telephone line or a power line must be installed. In addition, not all electronic devices are connected to a power line, such as a battery powered device, and there are cases where power connection is not easy.

In addition, since a small amount of data is generally transmitted through a network such as turning on a TV or a lamp, adjusting an air conditioner temperature, or driving a washing machine on a home network system, a wireless method has recently been applied to operations on a home network system. .

This wireless method is convenient to use because it does not require cable wiring and the mobility of the terminal or device is guaranteed. In addition, the structure of the network is easy to change and easier to install and maintain than the wired method.

However, most current home network systems have terminal-oriented visual limitations, and basic infrastructure is inadequate.

According to the present invention as a technical idea for achieving the object of the present invention, by downloading and embedding the mobile content connection program 110, connected through the Internet 200 fingerprint door lock 510, gas valve controller ( 520, a mobile communication terminal 100 for remotely controlling any one selected from the window intrusion detector 530 and the CCTV camera and checking a control state;

Download the mobile content access program 110 of the mobile communication terminal 100 connected through the Internet 200, convert the access domain name of the mobile communication terminal 100 to an IP address, DDNS settings Management / DDNS server 300 for managing the;

A home network server (400) for overall management to transmit a remote control or a controlled state of a device transmitted from the mobile communication terminal (100) connected through the Internet (200);

A fingerprint recognition door lock 510, a gas valve controller 520, and a window intrusion detector 530 that are remotely controlled using Zigbee communication based on the control data of the home network server 400; And

Presenting a home network control system comprising a CCTV camera 540 remotely controlled using Ethernet communication based on the control data of the home network server 400.

According to the present invention as described above, after connecting to the home network server through the Internet using a mobile communication terminal using a ZigBee communication or Ethernet communication can remotely control the fingerprint door lock, gas valve controller, window detector, and the like. By doing so, it is easy to build a home network system such as video security and access control security, and the construction cost is reduced.

In addition, the user can easily check the security status of the home anytime, anywhere, there is an effect that can immediately respond in case of emergency or external intrusion.
