Description of the invention (>) Power line transmission / reception devices 103 and 105 for receiving data; and an interface unit for transmitting and receiving data between terminal devices such as personal computers 101 and 107 102 and 106. However, the communication method used in the power line transmitting / receiving device according to the conventional technology has a problem that the reliability of the communication is reduced according to the load change. This is because the ON / OFF operation of various electrical devices connected to the power line and the This is due to the inherent noise environment generated by these electrical installations. That is, the communication method such as FSK or PSK adopted between the transmitting / receiving terminals is not good because of the noise environment around the power line and the load effect of various loads connected to the power line, so its impedance, That is, the transmission line constant varies greatly, so the signal transmission rate is low and the signal detection is not so reliable. In addition, the low signal transmission rate through the power line and the low reliability in signal detection are also caused by the difficulty in synchronously controlling the signal transmitted through the power line, because the characteristics of the line vary with the transmission channel or noise. And change.

Description of the Invention (>)Receiving; The device 'has a simple constituent circuit and is capable of transmitting and receiving a pulse data signal reliably through an electric power line at an ultra-high speed in an asynchronous manner. Still another object of the present invention is to provide an asynchronous power line transmitting / receiving device which uses a pulse data signal transmitter system whose pulse data signal is a 1-period sinusoidal shock pulse (1-period sinusoidal Shock pulses are hereinafter referred to as' pulse data signals,). To achieve these and other advantages, and in accordance with the purpose of the present invention 'as embodied and broadly described herein, it is provided with an asynchronous power line transmission / reception device comprising A transmission pulse of a digital terminal of a personal computer becomes a pulse data signal and transmits the pulse data signal to the pulse data transmission signal circuit of the other party through a power line, and a transmission circuit having a circuit for transmitting the power line through its receiving terminal Receives a pulsed data signal transmitted from the other party, removes noise, amplifies the pulsed data signal to a specific level and intercepts the amplified and level-cleaved pulsed data signal higher than a specific level A receiving circuit of the unit; a pulse data signal separation and detection unit for separating a transmitted pulse wave with a positive (+) pulse and a negative chirp pulse equivalent to a positive edge and a negative edge; and a pulse wave reproduction unit, It is used to set the positive (+) pulse interval of the pulse data signal separation and detection unit to a positive (+) set pulse. And the pulse interval of the negative pulse is positive (+) reset pulse, corresponding to the 1-period pulse data signal on the time base to configure these pulses as a pulse-setting-reset pair and pulse reset -Set the pair and only select the first pulse of each pair, so that if the selected pulse is a set pulse, 7 paper sizes are applicable to the Chinese National Standard (CNS) A4 (210 X 297 mm) '---------- · ϋΜΙ — order --------- line — (Please read the notes on the back before filling out this page) 488137 A7 B7 V. Description of the invention (屮), A high-level signal pulse wave system is generated, and if the selected pulse wave is a reset pulse wave, a low-level pulse wave signal system is generated to reproduce a transmission data pulse signal and transmit it To a PC interface. In addition, in the asynchronous power line transmitting / receiving device of the present invention, the positive edge and the negative edge of the data pulse are converted into a pulse data signal having mutually opposite potentials to be transmitted, so the transmission characteristics are independent of the What is the background noise or the load change of the power line? Both are fixedly maintained at y | x. At the same time, in the asynchronous power line transmitting / receiving device of the present invention, although it may occur when the load operates or changes in the power line The random pulse noise pulse wave has a higher level than the background noise of the power line (with the amplitude of the [// V] unit), reaching about 20 to 50 [dB] (10 to 300 times), but Since the period of a pulse noise pulse usually exhibits a low frequency characteristic expressed in [// sec], the pulse noise pulse wave can be compared with a pulse having a high frequency characteristic with a period of several nanoseconds [nsec] or less. Data signals are segmented and can be removed by frequency separation methods. Therefore, because the noise is completely removed by a noise removal unit using a two-stage processing frequency separation method (taking into account even random special noise), it is used in this data pulse The reliability of the reproduction unit to reproduce the data pulse is highly improved, and ultra-high data transmission can be achieved by a transmitter system having a pulse data signal with a period of [nsec] or less.

Description of the invention () In the receiving device, it may occur when the load of the power line changes. The amplitude of the noise pulse of the random pulse has a high level of about 20 to 50 dB, which is 10 to 300 times higher than the amplitude of the background noise of the power line with the amplitude of the micro-voltage unit ([AV]), and the noise of the pulse is The pulse width has a low frequency characteristic expressed in microseconds ([β sec]). However, because the time width of the pulse data signal has a high frequency characteristic below several nanoseconds ([nsec]), the noise pulse can be removed by filtering through a frequency separation method. Therefore, the noise removing unit adopting a frequency separation method that takes into account the 2-stage processing of even a series of random special noises completely removes the noise, so the data pulse wave reproduction unit can reproduce reliable data Pulse wave. At the same time, the data can be transmitted at an ultra-high speed due to the transmission method of the pulse data signal having a time width lower than several nanoseconds ([nsec]). As described so far, the asynchronous power line transmitting and receiving device according to the present invention, due to the low signal attenuation characteristics of the power line, and the electrical concentric plug with respect to the pulse data signal transmitted with a specific time width Because of the signal decay effect, low-level signals can be transmitted through power lines. At the same time, since the transmitted signal level is low, the electromagnetic interference (EMI) problem does not occur, and when the data is transmitted to a remote location, its fixed signal transmission characteristics can still be maintained. In addition, the asynchronous power line transmitting and receiving device can be applied to an ultra-high-speed power line communication network (LAN) architecture, a CCTV network architecture, a factory automation architecture, an underground wireless relay network architecture, and a radius of 2-3 kilometers, and豕 庭 电 窃 5 network architecture, or can be applied to control 14 This paper size applies Chinese National Standard (CNS) A4 specification (210 X 297 mm) 1J n ϋ m · ^^ 1 ϋ ϋ ϋ 1 · ^ ϋ nn 0 ^ 1.
