Description

Home Automation System by the combined remote controller

The present invention relates to a system for controlling a function of an electronic product controlled by an infrared remote control by connecting an existing integrated remote control (eg, Hanaro remote control) to the main board of our remote controller by wire and wireless. Devices can only use simple on / off control using wired and bus lines, and intelligent control is impossible. Accordingly, there is a need for a new type of system for controlling devices in a home or a corresponding space with a single device of a remote controller without attaching an attached control receiver to an existing device.

In recent years, the popularity of cyber apartments has been increasing. Basically, high-speed Internet networks in apartment complexes have been established, and Internet access services and local community services centered on various local lives have become common through various media such as PCs and TVs. Home automation systems are being developed that can remotely control home appliances and lighting fixtures with orders. Especially, Internet TV provides various information necessary for life such as newspapers, culture, sports, travel and health information, as well as shopping and stocks. Transactions, banking, and medical treatment can be handled regardless of location and time, saving time and economic costs for residents, as well as various home security services and information appliances such as remote meter reading, parking management, and fingerprint recognition. The 21st century new concept residential environment aimed at the safety and convenience of residents through connection. It is being made. The problem is that in order to use these home automation system services, a system must be built where remote control of home appliances and doors is desired. It is currently only available in some cyber apartments with systems from the time of construction. This means that the cost of applying existing technology to the first building is not high enough to meet the budgets of the building companies, and the cost of building the building is very difficult to add these functions to a single house. In this regard, an integrated processor that can simplify home automation system that is easy to apply in a realistic manner and needs to be simplified is needed.

Accordingly, in the present invention, to solve the problems as described above,

In order to provide complete control of home automation with a single control system when the user has internet access, communication is possible via the Internet. As a main device, commands can be transmitted from the data server while performing TCP / IP communication with the data server. Remote controller that controls the environment and status of various electronic products and equipments by communicating with remote controller by providing remote controller that transmits the status of lower equipment to server, DIO which controls on / off of near-siron, light, fluorescent lamp The system is composed of a controller, a keypad controller for arming and disarming, a power line modem that can control on / off of remote lights, fluorescent lamps and boilers.

The configuration and operation of the home automation system by the integrated remote controller of the present invention will be described below.

First of all, in the overall configuration, the user connects to the data server through the Internet, and sends commands to the subordinate equipment through the integrated remote controller that performs TCP / IP communication with the data server. At this time, the integrated remote controller is connected to DIO controller, keypad controller, power line modem, remote controller and wired / wireless to transmit the user's command to the subordinate device and check the status of the subordinate device to transmit the information to the main data server.

It performs TCP / IP communication with the data server and transmits commands from the data server and transmits the status of the underlying equipment to the data server.

a) It detects the signal from the sensor while communicating with the DIO controller and stores the camera's video in the main memory and sends the video data to the data server, and shuts off the main power in case of a disaster (fire, gas leak) and the data server. It transmits the emergency situation and transmits the camera's image data when requesting video communication.

b) Communicate with the keypad controller to arm and disarm.

c) Control remote equipment through power line modem.

d) Communicate with air conditioners, boilers, TVs, VCRs, etc. while communicating with the Rico controller, and specify the reservation and setting of temperature and humidity, and set the program recording and reservation of TVs, VCRs, etc.
