Description

System and method for controlling remotely using RF ID using RF ID

The present invention relates to a remote control system, and more particularly, to a remote control apparatus and method using the RF ID (Identifier) and the device.

In general, the remote control is equipped with a variety of functions each electronic set has through the transmission of radio frequency at a controlled frequency to a TV or video tape recorder, audio, air conditioner, cable broadcasting converter, satellite broadcasting converter, fan and other electronic sets. It is a device to control.

As described above, a remote controller for remotely controlling an electronic device set uses different frequency bands to prevent malfunctions of other devices by the makers producing the electronic device sets and the electronic device sets. Each remote control is provided.

Therefore, when using a plurality of sets of electronic devices, in order to remotely control each set of electronic devices need to operate a desired function through a remote control corresponding to each set of electronic devices, various complex problems in selecting a function This was derived.

In particular, if any remote control is lost due to careless handling of the user, in order to operate the corresponding electronic device set, the user manually manipulates the buttons provided on the electronic device set and selects a channel of the desired channel or other devices provided in the electronic device set. It caused an inconvenient problem to choose the function of.

Accordingly, in order to remotely control a plurality of electronic device sets with a single remote controller, an integrated remote controller having a control frequency code is set and used for each electronic device set produced by each manufacturer and a manufacturer.

This integrated remote control is implemented in several ways. The simplest method is to database the code of a supported device and store the database directly in the remote control's memory. In this method, the user finds the device he wants to control from the code table provided and inputs it directly. In this case, some models support updatable databases.

 Another way is product search via the Internet. In this case, the integrated remote control manufacturer provides control codes for products available on the Internet. The user connects to the Internet, downloads the code of the desired product, and updates the remote control. At this time, the remote control is equipped with an interface for receiving data by connecting to a device such as a PC or a network interface for directly accessing the Internet.

 Finally, there is a remote controller that implements the learning function. In this case, the user can copy the remote control of the device to be controlled with the integrated remote control and then control the device with the integrated remote control. Copying the remote control means inputting codes into the integrated remote control while the user directly operates one code corresponding to each key of the original remote control.

However, the biggest problem of the conventional integrated remote control technology is the difficulty in use. For example, in order to control the device, the user has to go through several steps to input the integrated remote control. If a new product comes out, it is necessary to check whether it supports this product. You must wait until it is unavailable or the database is updated. If it is impossible to update the database of the integrated remote control, you cannot register a new product and use it. Some products support the learning function, but to use this function, the user has to enter the keys one by one and use the learning function.

 In addition, the company that makes the product must manage the code values used in the remote control database and input new information about the product each time a new product is released.

 In addition, since the remote control itself has too much spec because it needs to add a function such as network or PC synchronization, the user is burdened in terms of price, operation method and size.

An object of the present invention is to provide a remote control device and method for remotely controlling a device using an RF ID.

Another object of the present invention is to provide a device with a built-in RF ID.

The device of FIG. 2 includes an RF ID chip unit 220 for providing control code information according to an ID request of the remote controller 120 and a device controller 230 for controlling a function operation according to IR control data of the remote controller 120. Equipped.

First, referring to the RF ID chip unit 220, the RF transceiver 212 extracts a code from a radio signal received from the remote controller 120 or converts a control code into a radio signal.

The memory unit 216 stores device control codes. For example, the control code may be 1) a device unique ID or a classifiable ID for identifying a company name, device type, device specification, etc., 2). Control basic data, 3). IR codes corresponding to the control key may be classified. Here, for example of the control basic data

4 is a flowchart illustrating a remote control method of a device and a remote control period using the RF ID according to the present invention.

First, the remote controller 120 searches for a device using a radio wave radiated to the device 110 (step 410).

In operation 420, the device 110 transmits an ID response message to the remote controller 120.

Subsequently, the remote controller 120 analyzes the ID response message to check whether the device type TV and the control target exist (step 430).

Subsequently, the remote controller 120 requests IR control data from the device 110 (step 440).

Subsequently, the device 110 transmits the control data stored in the RF ID chip to the remote controller 120 (step 450).

For example, the IR code transmission scheme may be configured as shown in Table 1. IR codes are slightly different for each company and have different transmission frequencies.

Brand Coding scheme Carrier Frequency (kHz) Code Length (bits) Canon Space 37.5 32 Goldstar Space 39.2 32 Philips Shift 36 14 Sony Pulse 40 15

The carrier frequency is the transmission frequency carrying the code and the code length is the actual IR code length. According to how the coding scheme configures logical data 1 and 0, three methods shown in FIG. 5 may be used, namely, (a) Space coded Signal, (b) Shift coded signal, and (c) Pulse coded signal.

Therefore, the device 110 must transmit control basic data such as coding scheme, carrier frequency, and code length of Table 1 before transmitting the IR control code value. In addition, the actual IR code includes a header code and a stop code to distinguish the product, so the header and stop codes are sent in advance rather than the header and stop codes for every IR code. It would be more efficient to transmit. Accordingly, the control data format transmitted through the RF ID chip can be configured as in the following example.

    Coding scheme: (Space, T = 550us)

    2.Carrier Frequency: (39.2 kHz)

    3.Code Length: (Header Code Length: 24T, Control Code Length: 6bits, STOP Code Length: 25T)

    4.Header Code: 111111111111111100000000 (1: Pulse High, 0: Pulse Low)

    5.Stop code: 1111111111111111000000001 (1: Pulse High, 0: Pulse Low)

    6.Control code (where 1,0 is Space coded signal)

        Power Key: 101010

        Mute Key: 100001

        -...

Subsequently, the remote controller 120 stores the control basic data and the IR code received from the RF ID chip in the device in the memory (step 460).

 Subsequently, a setting operation for controlling the device from the stored control basic data and the IR code is performed (step 470). Here, the setting operation is to adjust various parameters to fit the device 110 using control basic data and IR code information.

Accordingly, when the remote controller 120 receives the control basic data and the IR code information, the remote controller 120 generates a carrier frequency through its own timer like the IR control method of a general integrated remote controller, and generates an IR control code for a key value input by a user according to a coding scheme. Transmit (step 480).

When a user registers a device once by storing an IR code for each device, the user can select and control a desired device 110 in the remote controller 120 without re-registration.

Finally, when the device 110 receives the IR control data for the corresponding key from the remote controller 120 (step 490).

The present invention is not limited to the above-described embodiment, and of course, modifications may be made by those skilled in the art within the spirit of the present invention.

As described above, according to the present invention, the user can control all the home appliances through one remote control device without any other help, and only the user needs to control the home appliance before the user controls the home appliance. To register. In addition, device manufacturers can easily implement an integrated remote control by simply inserting an RF ID chip containing an IR code into the device. It also provides a basic way of home network and home control technology to tie home appliances.
