The present invention relates to an input or output device of an electrical or electronic device or an electronic product, and more particularly to an input or output device of an electrical or electronic device or an electrical and electronic device for power line communication, and to control a plurality of terminals using the input and output device. It's about the system. Here, each of the terminals means an electrical or electronic device or an electrical or electronic product.

In general, all electrical or electronic devices or electronic products have separate input and output devices. Moreover, the input and power supplies are also separated independently.

Therefore, all electrical or electronic devices or electrical or electronic products have input terminals independent of the power supply terminals in order to receive the supply voltage. In addition, these days, almost all electrical or electronic devices or electrical or electronic products are supplied with a DC power supply voltage using an adapter and thus cannot receive an input signal through a power line.

As a result, in order to perform power line communication, an intermediate medium means that is electrically connected between the input terminal and the power line was inevitably required.

However, the provision of such intermediate media means separately between input terminals and power lines in all electrical or electronic devices or electrical or electronic products is quite cumbersome and the processing of intermediate media means such as wires has not been easy. Moreover, radio processing of intermediate media means required corresponding system resources and was not economical to manufacture.

1 is a block diagram showing the configuration of a control system using a conventional communication device.

In FIG. 1, the control main body 200 controls the terminal 300 by receiving predetermined data by wire or wirelessly by communicating the internal communication device 100 from the external communication device 30.

The above-described conventional technology is described in Patent No. 0400364, Patent No. 0475194, and Patent Application No. 2003-0006488, and thus will not be described in detail here.

In this case, in order for the control main body 200 to control the terminal 300, a large amount of one-to-one corresponding system resources were required. In other words, in the case of wireless communication between the control body 200 and each terminal 300, the cost of installing the modem system is added, as well as the communication protocol or between each terminal 300 and the control body 200. In many cases, even when the communication system was installed because the data formats were not compatible with each other, the control body 200 did not control each terminal 300. In addition, since wired communication is newly installed when wired communication is performed between the control main body 200 and each terminal 300, not only the wiring is complicated but also the space is not neatly processed.

Thus, development of a terminal control system using power line communication is in full swing.

2 is a general configuration diagram of a terminal control system using power line communication.

The power line communication transmitter 10 and the power line communication receiver 20 generally include a power line connection unit 1, a power line coupling unit 2, a modulation / demodulation unit 3, and an interface unit 4, respectively.

However, the terminal control system using the power line communication as described above is limited in the communication distance to the wired communication between the control main body 200 and each terminal 300 inevitably required an intermediate medium for long distance communication. Accordingly, recently developed home network systems perform long distance communication using the Internet and then short-range communication using power line communication. This approach, however, was vulnerable to mobility and required another wire.

In addition, one of the near-field wireless communication method between the control body 200 and each terminal 300 has been studied in the infrared communication method. However, this method has a limited range of infrared light emission and reception, so communication has been limited in interlayer (first or second floor) or curved or curved portions.
