Research And Implementation Of Automatic Tuning System For High Power PSM Short Wave Transmitter

As the main channel for disseminating national politics and economic policies and the main means of leisure and entertainment,radio and television have begun to chase whether the performance of radio and television meets the above requirements.Traditional short-wave transmitters are not designed with automatic tuning functions,and they must rely on manual operations to achieve functions such as tuning and frequency replacement,resulting in adverse factors such as low efficiency and high cost.In addition,although some transmitters on the market currently have an automated system,there are problems such as inconvenient heat dissipation,large maintenance,frequent abnormalities,and slow operation.In order to improve the performance of radio and television,the automatic upgrading of short-wave transmitters is a method worth promoting and developing.This article conducts an in-depth study of thisFirst,the background,importance,significance and overall status of the research on short wave transmitters are summarized,and the research direction and structure level of the paper are clarified.Secondly,a lot of meticulous research is made on the composition and basic working principle of the high-power PSM short-wave transmitter system,and on this basis,the overall scheme of the high-power PSM short-wave transmitter automatic tuning system is designed.Finally,taking the overall plan as a guide,the hardware composition and design of the high-power PSM short-wave transmitter auto-tuning system are described in detail and tested and verified.Through FPGA and ARM embedded technology,the detailed design and hardware debugging verification of the interface communication between eachcomponent of the high-power PSM short wave transmitter automatic tuning system and the ARM and FPGA can not only reduce the interference of the magnetic field,but also ensure that the Normal operation in the corresponding environment.
