Embodiment Construction

[0022] Taking the domestic 220V / 50Hz low-voltage power line as the application object, the implementation method of the present invention will be described in detail in conjunction with the accompanying drawings and typical embodiments, but the scope of the present invention is not limited in any way.

[0023] Such as figure 1 As shown, the power line communication system using pulse modulation of the present invention includes a digital baseband signal processor 1 , a pulse generator 2 , a transmitting path 5 , a receiving path 11 , a coupler 6 and a power line 7 .

[0024] In more detail, the digital baseband signal processor 1 includes a transmitting unit 12 and a receiving unit 13 . Wherein, the transmitting unit 12 is connected with the pulse generator 2 , maps the original binary data into a corresponding digital signal, and transmits it to the pulse generator 2 . The receiving unit 13 is connected to the receiving path 11, and is used for processing the digital signal ...

Abstract

The invention relates to a data transmission technology adopting pulse modulation on a power line. The pulse modulation lies in that original binary data are mapped into corresponding digital signals through a digital baseband signal processor, the digital signals are transmitted to a pulse generator, the pulse generator generates corresponding simulated narrow pulse signals according to the different digital signals, and the simulated narrow pulse signals are directly loaded to the power line through a coupler.

Description

technical field [0001] The invention relates to the power line communication technology, in particular to a power line communication technology using pulse modulation on the power line medium. Background technique [0002] Power Line Communication technology (Power Line Communication) is a communication method that uses ordinary power lines as a communication medium to transmit data. It has the advantages of low cost, simple construction, convenient access, and easy expansion. It can be widely used in digital homes, intelligent buildings, and industrial Control, transportation and other fields. [0003] The power line itself is used to transmit power frequency sinusoidal AC signals, not for data transmission. Due to the complexity of the power line network structure and the diversity and time-varying nature of the load, the power line has its own unique defects as a communication medium, such as unpredictable noise, varying impedance, and signal attenuation. [0004] At pr...
