基于STM32及FPGA的双冗余网路切换系统的设计与实现

Dual Redundant Net Switching Equipment Based on STM32 and FPGA

针对批量双冗余网络切换测试效率低的问题,设计了一种使用LCD触摸屏作为人机交互界面,可根据输入要求定时、外部触发、手动切换自动完成双冗余网络切换的测试模块。模块包括STM32单片机电路、FAGA控制电路、触摸液晶屏单路与双冗余网络切换电路组成,通过触摸屏输入控制或者串口命令控制可实现8路双冗余网络A、B通道的切换。实际测试结果表明,切换后的网络信号质量良好、性能稳定。该设计使用简单,运行稳定可靠。

Dual redundant net are widely used today,while the special test environment and technology is not synchronously developed.To solve this problem,a kind of testing system of T Dual redundant net switching equipment based on STM32MCU and FPGA is designed in this paper.The designed system contains MCU used STM32 circuit,FPGA controlling circuit,TFLCD displaying circuit and dual redundant net switching circuit.This testing system is simple and small,while it can switch8 dual redundant net channels using TFLCD.This system performed accurately,stably and reliably.
