Description

technical field [0001] The invention relates to the technical field of automatic tuning, in particular to an automatic tuning control system based on a single-chip microcomputer and FPGA. Background technique [0002] Automatic tuning technology refers to automatically adjusting the high-frequency loop components of the transmitter to the resonance position corresponding to the frequency according to the currently specified operating frequency during the tuning process. When the upper computer sends a certain frequency information, the main control board will automatically reach the preset position according to the frequency information, and complete the frequency preset. At the same time, affected by the weather and geographical location, it is necessary to measure the power amplifier current, power amplifier voltage, middle tank current, middle tank voltage, antenna current, and antenna voltage to make the tuning state reach a pure resistance state, automatically adjust th...
