Description

Home automation system using portable terminal loaded remote control function

The present invention relates to a home automation system using a portable terminal equipped with a remote control function, and includes a home appliance (for example, a door phone, an indoor light, a TV, a VTR, an air conditioner, a refrigerator, etc.) to which the remote control function is mounted and controlled. The present invention relates to a home automation system using a portable terminal equipped with a remote control function for downloading a control signal code value from a home automation center or a PC and remotely controlling a specific home appliance through a wired / wireless communication network, an infrared ray, or an RF method.

In general, the remote control is currently used as a remote controller of many home appliances. However, since the signal system varies depending on the type of semiconductor applied to the infrared remote controller, the home appliance had to have a separate remote controller for the device. Therefore, when there are many home appliances, it is inconvenient to manage each remote control because a plurality of remote controls must be used. To solve this, a universal remote controller has been developed that integrates multiple remote controllers into one. However, even using such a universal remote control, it is difficult to apply to new home appliances, etc., and has a disadvantage in size and weight. In particular, since the home universal remote control can be used by the whole family, even if the remote control is integrated with a plurality of remote controls do not know the place where it can be a lot of time to find a remote control when needed.

On the other hand, the number of subscribers of mobile communication services has exploded in recent years, and the base has expanded to the point where most people now have mobile communication terminals. In the early days, these mobile terminals were mainly used to provide voice services for calls between subscribers. A mobile communication terminal is generally used by a subscriber, but when providing only a voice service, it can never be said that the time actually used by the subscriber is large. In other words, it can be said that a mobile communication terminal usually uses a large portion of call waiting time and a ratio of time in which communication is actually performed. Recently, the mobile communication service is not limited to the voice service, but also provides various data communication such as text information and image information. As a result, the use rate of the mobile communication terminal has increased, and it performs various functions provided by the mobile communication service.
