这项工作设计和讨论了通过光纤传输模拟脉冲的计算机数据获取系统,供中子发生器闭环控制之用,成功地在电位差为150KV两端间作了数据获取试验,模拟脉冲幅度的传送精度优于±1%。可推广应用于被控现场存在强电干扰的闭环控制系统或数据传输系统。
This work designs and discusses a computer data acquisition system for transmitting analog pulses over optical fiber for closed loop control of neutron generators. Data acquisition experiments were successfully conducted between both ends with a potential difference of 150 kV. The accuracy of the transmitted pulse amplitude was excellent At ± 1%. It can be widely used in the closed-loop control system or data transmission system where there is strong electric interference at the scene of the charge.
