Description

Communication field using power line magnetic field and its system {Magnetic field based power transmission line communication method and system}

The present invention relates to a method and system for using a power line network as a communication network with a general power transmission function, and more particularly, to telephone (voice) communication through a magnetic field component of electromagnetic radiation formed along a power line. It relates to a communication method and system using a power line magnetic field capable of information communication between subscribers, including.

Conventional technologies using power lines as communication media are known in the 1930's (US Pat. Nos. 2,032,360, 2,264,385 and 2,264,396) developed for telephony in an outlying area. These systems suffer from the technology of superimposing carriers on the electrical components of electromagnetic radiation formed along power lines, but with the limitations of analog bandwidth, attenuation of signals, and the inability to handle more than one call at the same time.

In addition, other conventional analog-based systems (US Pat. No. 5,565,450) relate to the transmission of carrier frequencies above 1 MHz between power transformers, but also to power line electromagnetic fields that interfere with transmission signals when power is supplied to electrical equipment connected to the power wiring network. There is a problem that noise occurs.

On the other hand, in order to solve the noise problem of the analog transmission, a method of transmitting a digital signal instead of an analog carrier using a digital packet (US Patent Nos. 5,554,968, 5,559,377 and 4,471,399) has been proposed, The technology uses the electrical components of the electromagnetic radiation of the power line, which still causes the transmitted signal to mix with other signals while passing through the power line, causing communication disturbances such as noise and interference, or distorting data while passing through the transformer. There is a problem.

Accordingly, the present invention has been invented in view of the above-mentioned problems, and the power wiring network, which is already constructed, is used as a communication medium, but unlike the conventional electric field elements of the power line, it is formed around the power line when electricity flows. By using the magnetic field area as a medium for information transmission, the purpose of the present invention is to provide a more stable data transmission, a faster transmission speed and an economical and efficient communication system.

The actual flux does not attenuate to zero and provides a flux envelope 64. The magnetic envelope envelope focuses the synthetic perforated lens 60 on a magnetic field around the power line 26 and then outputs the MASER 50. At this time, the power line 26 serves as a magnetic waveguide for outputting the coherent acoustic signal of the MASER 50. Preferably, the amplitude of the transmission medium is typically about 10% smaller than the amplitude of the electromagnetic wave carried by the power line so that no excessive radiant energy is generated beyond the range of the general power network.
