Power line carrier communication experiment platform and experiment method

Abstract

The invention discloses a power line carrier communication experiment platform which comprises a sending end, a receiving end, a power line, a first LED output module, a second LED output module, a first single-chip microcomputer small system, a second single-chip microcomputer small system, a first carrier communication module, a second carrier communication module, a first coupling circuit, a second coupling circuit and a main control circuit. According to the invention, the first single-chip microcomputer small system reads a switching input quantity, codes the switching input quantity and sends the switching input quantity to the first carrier communication module for modulation, the switching input quantity is coupled to a power line through the coupling circuit, the second coupling circuit receives a carrier signal and transmits the carrier signal to the second carrier communication module, and the received carrier signal is demodulated and then transmitted to the second single-chip microcomputer small system for processing. The power line carrier communication experiment platform enables students to carry out power line carrier communication experiments on the platform, understand the characteristics of the communication technology, expand the scope of knowledge and exercise the practical ability, and further can deepen the understanding of the unique communication mode principle of power line carrier communication.

Description

technical field [0001] The invention relates to the technical field of electronic communication, in particular to an experimental platform for power line carrier communication. Background technique [0002] In electrical majors such as electronic information engineering, communication engineering, electronic science and technology, automation, and electrical engineering, communication experiments are an important experimental teaching content. The contents involved mainly include serial asynchronous, infrared, Ethernet, CAN, etc. , 232, 485, Modbus, Profibus, Zig-Bee, WiFi, 2.4G, etc. Power line communication (PLC) is a communication method that uses power lines as the transmission medium to perform data transmission and information exchange through carrier waves. It is widely used in street lamp control systems, remote automatic meter reading, and park energy-saving management and control. However, as a communication method that does not require a dedicated transmission me...
