摘　　要：介绍北京谱仪上的快控制系统的研究与设计。快控制系统主要由6种VME模块组成,它完成系统时钟和快控制命令的扇出和读出状态信号的处理与报警功能。根据不同的要求信号分别使用光纤串行和LVDS标准的差分并行两种数据传送方式。主要逻辑用现场可编程的逻辑器件(FPGA)实现,系统按照高速电路的设计要求设计。The Fast Control System（FCS） for BESⅢ is under development It is consisted of 6 types of VME modules The one task of FCS is to send trigger commands to DAQ, such as ‘pass level 1 trigger’ （L1） , clocks and some control signals. Another task is to collect read-out state informations from different electronics systems and give out error report. High- speed serial optical fiber transmission and LVDS techniques are used to transfer signals between the FCS and other systems. The high-speed digital design techniques are applied in circuits. The FPGAs are used for FCS logic implementations.
