Abstract
In the research of power line carrier data transmission, STC89C52 chip is selected as the core microprocessor and KQ130F carrier module as the receiving and transmitting carrier of the system. The optimization of modulation and demodulation rate and the reduction of bit error rate are realized by improving the programming algorithm in the transmission process. In the analog LED street lamp monitoring system, the PC performs the data transmission test by setting up the hardware test platform through the actual application process of the power line carrier to the terminal control.
