Design Of RSR Control System Based On SOPC

With the development of science and technology especially the technology of aeronautics and astronautics, the exploration ability of human become stronger and stronger. Deep space exploration includes the exploration and using of space outside the Earth in the 21st century. The application of software defined radio technology promotes the development of deep space exploration. So the study of radio science receiver (RSR) is significant for deep space exploration.Firstly, this thesis concluded several representative receivers which were designed by some various research institutes in China and abroad, and analyzed the characteristics of their hardware. Besides, this thesis studied the design characteristics and control systems of several Radio Science Receivers of Southeast University (SEU), then proposed an solution of control system in RSR’s FPGA based on System on Programmable Chips (SOPC) technology. So the RSR won’t need the separate control system module any more. And the cost of resource is decreased. This design will make the design of RSR’s hardware and software easier and more efficient and improve the reliability of RSR system. This thesis designed the SOPC platform respectively from two aspects of hardware and operating system software platform mainly for self-designed RSR system. Via the requirement analysis of RSR control system and the study of characteristics of RSR’s hardware and software system, this design used MicroBlaze soft core processor as the main processor and designed the hardware platform of RSR’s control system based on it in FPGA. Then, this design used PetaLinux system as the operation system of RSR’s control system and completed its kernel cutting and transplantation successfully.At last, this design completed the design of control application software of RSR, including the configuration of the clock chip with two kinds of clock signals of 2304MHz and 288MHz, the design of ADC configuration with 1.152Gsps Sampling Rate in Four-channel Mode, the implementation of network communication in digital processing module by light weight internet protocol and the necessary driver program and so on.
