摘　　要：针对各种直径光纤的熔接需求,实现大直径光纤熔接和拉锥、小直径光纤快速熔接的目的,该系统采用启明星ZYNQ开发板作为主控,使用Verilog语言和Vivado软件编写并下载固定范围频率且占空比可调的PWM信号,通过ADS1256芯片采集电路中电流大小,进而对PWM信号占空比进行实时调整,使电极放电的电流强度维持在一个比较稳定的状态,从而构成了光纤熔接机的放电子系统。通过重复进行放电实验,得出在50%和40%占空比Boost升压、相位相差三分之一的PWM信号控制下,系统放电电弧相对均匀,且熔接效果最好。In response to the fusion requirements of various diameter optical fibers,the system aims to achieve the fusion and taper of large diameter optical fibers,as well as the fast fusion of small diameter optical fibers.The system uses the STAR ZYNQ development board as the main control,and uses Verilog language and Vivado software to write and download PWM signals with fixed frequency range and adjustable duty cycle.The ADS1256 chip collects the current size in the circuit,and then adjusts the duty cycle of the PWM signal in real-time,The current intensity of electrode discharge is maintained in a relatively stable state,thus forming the electron discharge system of the fiber optic fusion splicer.Through repeated discharge experiments,it was found that under the control of a PWM signal with a Boost voltage of 50%and 40%duty cycles and a phase difference of one-third,the discharge arc of the system is relatively uniform and the fusion effect is the best.
