摘　　要：智能电网的快速发展使电力系统的架构越来越复杂,亟需开展电力无线专网规划实测设备研究与应用。为解决这个问题,设计了由现场可编程逻辑门阵列(FPGA)和AD9364组成的射频接收和频谱分析硬件系统。从FPGA实现角度详细说明了该系统各部分的功能实现。该射频接收机使用AD9364射频捷变收发器实现了分时长期演进(TD-LTE)230 MHz信号的接收,简化了射频接收机的硬件系统结构。为提高整体的频谱分析能力和速度,FPGA实现对接收信号的子信道划分并对子信道进行硬件快速傅里叶变换(FFT)操作。结果表明该接收机工作正常,能正常接收TD-LTE 230 MHz信号,频谱分析能力出色,该硬件系统可以用于电力无线专网规划的硬件部分使用。The rapid development of the smart grid makes the architecture of the power system more and more complex,and there is an urgent need to carry out research and application of measurement equipment for power wireless private network planning.To solve this problem,a hardware system for RF receiving and spectrum analysis composed of FPGA and AD9364 was designed.From the perspective of FPGA implementation,the function realization of each part of the system is explained in detail.The radio frequency receiver uses the AD9364 radio frequency transceiver to realize the time-sharing long-term evolution(TD-LTE)230 MHz signal reception,simplifying the hardware system structure of the radio frequency receiver.In order to improve the overall spectrum analysis capability and speed,FPGA realizes the sub-channel division of the received signal and performs the hardware FFT operation on the sub-channel.The result shows that the receiver works normally,can receive TD-LTE 230 MHz signal normally,and has excellent spectrum analysis ability.The hardware system can be used for the hardware part of electric power wireless private network planning.
