摘　　要：为了快速验证喷泉钟技术方案,设计搭建了一种基于Labview图形化编程环境的控制系统,硬件上使用标准信号板卡和商用外围电路模块,软件上采用主任务循环结合硬件触发的方式。经测试,控制系统的信号同步和控制精度可以达到μs量级,Ramsey谱线线宽为1.65 Hz,喷泉钟秒稳大约为1.18×10^(-12),满足了喷泉钟对激光、微波和数据采集等要素的基本控制要求,实现了喷泉钟的正常运行。In order to quickly verify the technical scheme of fountain clock,a kind of control system based on Labview graphical programming environment is designed,it uses standard signal boards and commercial peripheral circuit modules as hardwares,and programs the main task in a loop structure with hardware triggering.The test results show that the signal synchronization and control accuracy of the control system can reachμs magnitude,the Ramsey spectral line width is 1.65 Hz and the fountain clock’s stability is about 1.18×10^(-12) at 1 second.Therefore,the control system can meet the basic requirements of the fountain clock for laser,microwave,data acquisition and other elements,realizing the normal operation of the fountain clock.
