(English Abstract)
In this paper£¬ we implemented high-performance concurrent control system which manages whole RF systems with digital type and communicates with remote station on both wire and wireless networking. It consists of FPGA (Field Programmable Gate Array) part which controls forward/reverse LPA(Linear Power Amplifier), forward/reverse LNA(Low Noise Amplifier), channel card, wire/wireless TCP/IP£¬ etc£¬ master microprocess(AVR), which manages the whole control system, Slave microprocessor which communicates SA(Spectrum Analyzer) and observes frequency spectrum of each channel with the resolution of 5KHz£¬ 10 channel card microprocessor which independently observes each channel card and sets frequency synthesizer in channel card, and other peripherals and logics. The whole system is divided to two parts of H/W (hardware) and S/W (software) considering operational efficiency and concurrency, and implementation and cost. H/W consists of FPGA and microprocessor. We expected the optimized operation through H/W and S/W design and hybrid H/W architecture.
