光纤通信控制器的设计初衷是在效率、成本、个性化、稳定性等方面对光纤通信质量进行提升,但以往的控制器未能实现光纤通信信号平稳控制。因此,设计一种光纤通信中的信号平稳控制器,其在嵌入式电子控制之上设计三层环状分布式控制结构,采用串行同步控制方法稳定光纤通信信号。控制器选择低压正发射极耦合逻辑接口进行控制命令的光纤串行传输,通过“飓风”系列EF1C12型号的FPGA进行整体管控,并对JTAG配置电路实施设计,进一步完善了控制器控制功能。实验结果表明,所设计的控制器实时性强、可靠性高,能够实现对光纤通信信号的平稳控制。 The original design of optical fiber communication controller is to improve the quality of optical fiber communication in terms of efficiency, cost, personalization and stability, but the former controller failed to achieve the smooth control of optical fiber communication signal. Therefore, the design of a signal smoothing controller in optical fiber communication designs a three-layer annular distributed control structure on the embedded electronic control, and uses a serial synchronous control method to stabilize the optical fiber communication signal. The controller chooses the low-voltage positive emitter-coupled logic interface to carry out the serial control of the optical fiber transmission. The system is controlled by the “Hurricane” series EF1C12 FPGA and the JTAG configuration circuit is designed to further improve the controller control function. The experimental results show that the designed controller has high real-time and high reliability, and can realize the smooth control of optical fiber communication signal.
