Problems solved by technology

[0003] figure 1 The power line channel noise amplitude-frequency characteristic diagram is shown. It can be seen that the power line channel is a nonlinear time-varying, fast-fading system. It is a very challenging task to estimate channel delay and eliminate burst noise interference. High data rate High signal-to-noise ratio is required, and conventional HPLC does not work reliably for OFOM techniques that work well in wireless communications

Abstract

The invention relates to a high-speed reliable Internet of Things power broadband carrier system, and the system is characterized in that a sending end comprises a zero crossing point detection circuit which is used for detecting a zero crossing point of a power line; a modulation circuit which is used for modulating a signal to a power line carrier at a zero crossing point; and a transmitting circuit which is used for transmitting the modulated signal through the power line.

Description

technical field [0001] The present application relates to the technical field of the next generation information network industry, and in particular to a high-speed and reliable Internet of Things power broadband carrier HPLC (High-speed Power Line Carrier, high-speed power line carrier) system. Background technique [0002] HPLC is a high-speed power line carrier, also known as broadband power line carrier, which is a broadband power line carrier technology for data transmission on low-voltage power lines. The broadband power line carrier communication network is a communication network that uses power lines as the communication medium to realize the aggregation, transmission and interaction of low-voltage power users' electricity consumption information. Broadband power line carrier mainly adopts Orthogonal Frequency Division Multiplexing (OFDM) technology, and the frequency band uses 2MHz-12MHz. Compared with the traditional low-speed narrowband power line carrier techno...
