Field of the Invention The present invention relates to integrated control of home appliances, and more particularly, to an integrated interface device for home appliances having improved efficiency by providing a data communication method and an interfacing standard for integrated control.

In general, each product such as a TV, a VCR, a refrigerator, a washing machine, etc. in a home has a separate control switch (SW) or a remote controller for remote controlling the device.

In order to operate home appliances, a user usually uses the control device to separately operate each device.

In the case of a TV, various functions such as channel selection, sound mode selection, wide function, and caption function are independently controlled / operated using a control device such as a remote controller that controls the system.

Similarly, in the case of a VCR, a separate control device is used to independently control / operate various functions such as scheduled recording, selective playback, and parental control.

In particular, these TVs and VCRs are closely related to each other and have different control schemes.

At present, methods for integrating and controlling these devices have been proposed.

In this way, a TV, a VCR, a washing machine, or the like incorporating a clock or timer function separately controls the operation mode settings, for example, the operation of the reservation mode.

The home appliance control method of the prior art has the following problems.

TV, VCR, washing machine, etc. with built-in clock or timer function control each operation mode setting, for example, operation of reservation mode separately, and it is difficult to operate efficiently when reservation / execution of operation mode.

The present invention has been made to solve the problems of the conventional method of controlling and operating the home appliance, and provides an integrated interface device for home appliances with improved efficiency by providing a data communication method and an interfacing standard for integrated control.

1 illustrates electronics used in homes, where each device is linked to a data bus channel.

The monitor manages the whole system and allows the user to display the control and status of each device.

Each household appliance connected to the data bus has its own ID number.

As described above, the data communication method in the system having the interface structure to enable the integrated control is as follows.

Communication data is composed of a series of Bit strings in a serial manner, as shown in FIG. That is, the format of the data transmitted through the communication data bus is specified. First, the ID number assigned to each device is selected in the ID area so that the data can be read and written by the desired device.

In the read / write area, data for determining whether to write or read data to the selected device is formatted.

In the Date, Hour, and Min areas, data is exported to update the currently set time.

The control code for setting the function of the device is then transmitted and has a status display data area to return its status.

Here, ID is 4bit, R / W: 1bit, Date: Year (8bit), Month, Day (4bit) Control Code: 8bit, Status Display Data: 1bit). That is, in the communication method according to the control of the integrated home appliance of the present invention, a total of 26 bit strings are transmitted or received. In this case, the time data is read from the clock ID # 1 connected in FIG. 1 and transmitted to each device.

Therefore, the timer unit that existed separately in each device is not configured in the other device.

This means that the time different from one device to another can be set to a certain number of minutes, and the function control of each device by reservation recording and alarm setting is integrated.

The interfacing required for the integrated control according to the present invention will now be described.

The first block of data transmitted through the data channel is an ID number. That is, it is determined whether the ID number of the 4-bit code is its own in preparation for receiving data from the IR sensor 32.

As shown in FIG. 4, the 1T period of the synchronization clock corresponds to 1 bit of incoming data, and the edge trigger 33 and the decoder 34 perform L and H discrimination in this section.

The decoder 34 first determines the data input during the 4T section.

For example, in the case of FIG. 4, it is assumed that a value of "1001" comes in, and if this value is its own, it is determined whether to accept data or output to the light emitting diode unit 38 during the next 1T. Here, 1T is a read / write bit. That is, in the 1st: 4T section (ID) and the 2nd: 1T section (Read / Write), will the decoder 34 continue to receive data after decoding the data, or the encoder 40 will send the desired data to the LED unit ( 38) to inform the control unit 35 whether to output through the role of blocking one of the two devices.
